From 88b1bc8518b1d73c9e04154cc1dc8fcbc6b8cc61 Mon Sep 17 00:00:00 2001 From: deepfates Date: Sun, 22 Mar 2026 21:31:14 -0700 Subject: [PATCH 001/154] Add conformance runner and fix 71/71 spec divergences Build a tests.yaml conformance runner (loader, runner, expect) that exercises the Elixir implementation against the shared 71-case behavioral spec. Fixed all discovered divergences: - call_entity raises on error in code medium (COMP-6, COMP-8) - cantrip_error propagation through child entities (COMP-8) - child turn sequence preservation in parent loom (COMP-5, LOOM-8) - ACP session inference when sessionId omitted (PROD-6, ENTITY-5) - malformed done call treated as error, not termination (LOOP-7) - tool result ID mismatch validation (LLM-7) - circle rejects missing medium declaration (MEDIUM-1) 198 tests, 0 failures. --- ex/lib/cantrip.ex | 5 +- ex/lib/cantrip/acp/protocol.ex | 15 +- ex/lib/cantrip/circle.ex | 60 ++- ex/lib/cantrip/code_medium.ex | 9 + ex/lib/cantrip/entity_server.ex | 126 +++-- ex/lib/cantrip/fake_llm.ex | 30 +- ex/lib/cantrip/llm.ex | 4 + ex/mix.exs | 7 +- ex/mix.lock | 2 + ex/test/conformance_test.exs | 218 ++++++++ ex/test/divergence_fixes_test.exs | 357 +++++++++++++ ex/test/m1_config_test.exs | 9 +- ex/test/m1_llm_contract_test.exs | 8 +- ex/test/m22_summon_test.exs | 6 +- ex/test/m23_streaming_test.exs | 6 +- ex/test/m2_loom_api_test.exs | 8 +- ex/test/m2_loop_runtime_test.exs | 14 +- ex/test/m3_fork_test.exs | 2 +- ex/test/m3_loom_auto_storage_test.exs | 2 +- ex/test/m3_loom_dets_storage_test.exs | 2 +- ex/test/m3_loom_mnesia_storage_test.exs | 2 +- ex/test/m3_loom_storage_test.exs | 4 +- ex/test/m3_turn_structure_test.exs | 4 +- ex/test/m4_circle_runtime_test.exs | 5 +- ex/test/m5_composition_extended_test.exs | 22 +- ex/test/m6_production_test.exs | 9 +- ex/test/m7_hot_reload_test.exs | 8 + ex/test/support/conformance/expect.ex | 492 +++++++++++++++++ ex/test/support/conformance/loader.ex | 187 +++++++ ex/test/support/conformance/runner.ex | 638 +++++++++++++++++++++++ 30 files changed, 2160 insertions(+), 101 deletions(-) create mode 100644 ex/test/conformance_test.exs create mode 100644 ex/test/divergence_fixes_test.exs create mode 100644 ex/test/support/conformance/expect.ex create mode 100644 ex/test/support/conformance/loader.ex create mode 100644 ex/test/support/conformance/runner.ex diff --git a/ex/lib/cantrip.ex b/ex/lib/cantrip.ex index f7aab2de..f3f9e92e 100644 --- a/ex/lib/cantrip.ex +++ b/ex/lib/cantrip.ex @@ -342,6 +342,9 @@ defmodule Cantrip do {:ok, result, next_cantrip, loom, meta} -> {:ok, result, next_cantrip, loom, meta} + {:error, reason, next_cantrip} -> + {:error, reason, next_cantrip} + {:error, reason} -> {:error, reason, cantrip} end @@ -388,7 +391,7 @@ defmodule Cantrip do {:error, "cantrip must have at least one truncation ward"} true -> - :ok + Circle.validate_medium(circle) end end diff --git a/ex/lib/cantrip/acp/protocol.ex b/ex/lib/cantrip/acp/protocol.ex index 35fd6f2a..46017506 100644 --- a/ex/lib/cantrip/acp/protocol.ex +++ b/ex/lib/cantrip/acp/protocol.ex @@ -36,8 +36,12 @@ defmodule Cantrip.ACP.Protocol do params = request["params"] || %{} cwd = params["cwd"] + # Default cwd to system tmp dir if not provided + cwd = if is_binary(cwd) and cwd != "", do: cwd, else: System.tmp_dir!() + params = Map.put(params, "cwd", cwd) + cond do - not is_binary(cwd) or Path.type(cwd) != :absolute -> + Path.type(cwd) != :absolute -> {state, [err(id, -32602, "cwd must be an absolute path")]} true -> @@ -56,7 +60,7 @@ defmodule Cantrip.ACP.Protocol do def handle_request(state, %{"method" => "session/prompt"} = request) do id = request["id"] params = request["params"] || %{} - session_id = params["sessionId"] + session_id = params["sessionId"] || infer_session_id(state) prompt_payload = params["prompt"] || params["content"] || params["text"] || params with {:ok, session} <- fetch_session(state, session_id), @@ -81,6 +85,13 @@ defmodule Cantrip.ACP.Protocol do {state, [err(request["id"], -32601, "method not found")]} end + # When sessionId is not provided and exactly one session exists, use it. + defp infer_session_id(%__MODULE__{sessions: sessions}) when map_size(sessions) == 1 do + sessions |> Map.keys() |> hd() + end + + defp infer_session_id(_state), do: nil + defp fetch_session(state, session_id) do case Map.fetch(state.sessions, session_id) do {:ok, session} -> {:ok, session} diff --git a/ex/lib/cantrip/circle.ex b/ex/lib/cantrip/circle.ex index 3e9ca28e..a426a232 100644 --- a/ex/lib/cantrip/circle.ex +++ b/ex/lib/cantrip/circle.ex @@ -3,7 +3,7 @@ defmodule Cantrip.Circle do Circle configuration only (M1): gates + wards + medium type.

Each request runs in a Connection Task concurrently. - AgentHandler stores sessions and last_answer in public ETS - meta field on NewSessionRequest passes through to runtime (for LLM injection in tests) - Conformance runner updated to use AgentHandler with JSON reply reconstruction - Familiar and divergence tests migrated to typed ACP structs - Stdio integration test covers full JSON wire format via spawned BEAM --- ex/lib/cantrip/acp/agent_handler.ex | 164 ++++++++++ ex/lib/cantrip/acp/protocol.ex | 180 ----------- ex/lib/cantrip/acp/server.ex | 53 +--- ...cess_test.exs => acp_agent_stdio_test.exs} | 71 +++-- ex/test/acp_agent_test.exs | 138 ++++++++ ex/test/divergence_fixes_test.exs | 140 +++------ ex/test/familiar_test.exs | 46 +-- ex/test/m11_acp_protocol_test.exs | 296 ------------------ ex/test/m11_acp_server_test.exs | 26 -- ex/test/m14_acp_fixtures_test.exs | 83 ----- ex/test/m15_acp_transcripts_test.exs | 108 ------- ex/test/support/conformance/runner.ex | 161 +++++++++- 12 files changed, 592 insertions(+), 874 deletions(-) create mode 100644 ex/lib/cantrip/acp/agent_handler.ex delete mode 100644 ex/lib/cantrip/acp/protocol.ex rename ex/test/{m16_acp_stdio_process_test.exs => acp_agent_stdio_test.exs} (57%) create mode 100644 ex/test/acp_agent_test.exs delete mode 100644 ex/test/m11_acp_protocol_test.exs delete mode 100644 ex/test/m11_acp_server_test.exs delete mode 100644 ex/test/m14_acp_fixtures_test.exs delete mode 100644 ex/test/m15_acp_transcripts_test.exs diff --git a/ex/lib/cantrip/acp/agent_handler.ex b/ex/lib/cantrip/acp/agent_handler.ex new file mode 100644 index 00000000..25f466a2 --- /dev/null +++ b/ex/lib/cantrip/acp/agent_handler.ex @@ -0,0 +1,164 @@ +defmodule Cantrip.ACP.AgentHandler do + @moduledoc """ + ACP agent handler backed by f1729's agent_client_protocol library. + + A plain module — no GenServer.

Adapters report what the LLM said (content + tool_calls), nothing more. Code extraction from markdown in content was silently hiding model errors — if the LLM doesn't use the elixir tool as tool_choice requires, that's an error the entity should see and steer from, not something to paper over. **Single code extraction path.** Entity server extracts code only from tool_calls via extract_code_from_tool_call. No fallback to content. FakeLLM normalizes %{code: "..."} shorthand into proper tool_call format internally so all 308 tests exercise the real path. **LLM thinking preserved.** When reasoning models produce content alongside a tool call, it's now emitted as {:thinking, content}, preserved in the utterance for the loom, and shown faint in the CLI renderer. Previously this content was emitted as {:text} (causing duplicate display with the code box) and dropped from the loom. **Familiar redesigned as orchestrator.** Removed read_file gate — the Familiar navigates with list_dir/search and delegates actual work to children. System prompt rewritten around delegation patterns. Children get an informative default prompt about returning concise results. **Renderer improvements.** Removed all truncation. Gate results summarized by size (small results shown, large ones as metadata). Child events indented with depth tracking. Child final_response suppressed from stdout. Code eval gate events suppressed (code box covers it). Reasoning model max_tokens warning fixed by detecting provider prefix in model names. **Context window protection.** format_code_feedback summarizes large gate results (>500 bytes) since the entity has full data in variables. Matches the RLM principle: entity sees metadata in conversation, full data in variables, complete record in the loom. Also: list_dir returns "name (file)" / "name (dir)" annotations. --- ex/lib/cantrip/circle.ex | 37 +-- ex/lib/cantrip/cli/renderer.ex | 221 ++++++++++-------- ex/lib/cantrip/entity_server.ex | 83 +++++-- ex/lib/cantrip/fake_llm.ex | 25 +- ex/lib/cantrip/familiar.ex | 67 +++--- ex/lib/cantrip/llms/anthropic.ex | 2 +- ex/lib/cantrip/llms/gemini.ex | 1 - ex/lib/cantrip/llms/helpers.ex | 19 -- ex/lib/cantrip/llms/openai_compatible.ex | 1 - ex/lib/cantrip/llms/req_llm.ex | 29 ++- ex/test/cli/renderer_test.exs | 22 +- ex/test/familiar_test.exs | 82 +------ ex/test/m20_anthropic_adapter_test.exs | 5 +- ex/test/m24_gemini_adapter_test.exs | 5 +- ex/test/m8_openai_compatible_adapter_test.exs | 4 +- 15 files changed, 328 insertions(+), 275 deletions(-) diff --git a/ex/lib/cantrip/circle.ex b/ex/lib/cantrip/circle.ex index 1616ce7f..7fd991ee 100644 --- a/ex/lib/cantrip/circle.ex +++ b/ex/lib/cantrip/circle.ex @@ -231,7 +231,9 @@ defmodule Cantrip.Circle do Available host functions (closure bindings, top-level only): #{gate_lines} - Variables persist across turns.

Instead of fighting the box model, switch to left-border-only code blocks (╷│╵) that compose naturally with depth indentation. This follows Tufte's principle: every element of ink should carry information. The full box border was redundant — the code content is already visually distinct. A left border marks "this is the entity's utterance" with minimal horizontal cost.

This eliminates the fragile depth counter in the CLI renderer and solves event interleaving for concurrent children. Gate call events now include kind (:read, :search, :edit, :execute) and args_summary (key argument like the file path or search pattern). The CLI renderer shows "▸ read_file: README.md" instead of "▸ read_file". The ACP bridge uses kind for proper ACP ToolKind mapping and builds human-readable titles from args_summary. Design informed by ACP protocol (tool calls carry kind, title, status, locations), clig.dev (human-readable first), Tufte (every element carries information), and Rich's tree rendering (nodes contain rich content). Changes: - entity_server.ex: emit_event wraps events in {envelope, event}; gate observations carry args; gate_kind/1 and args_summary/2 helpers - code_medium.ex: args threaded into pushed observations - renderer.ex: all clauses accept {envelope, event}; depth from envelope; args_summary in tool_call display; medium-aware code block language tag; no mutable depth state - json_renderer.ex: envelope fields in JSON output - event_bridge.ex: proper ACP kind/title from enriched events; thinking event support; bare event fallback for text_delta - Tests updated for new event shape --- ex/lib/cantrip/acp/event_bridge.ex | 42 ++++++-- ex/lib/cantrip/cli/json_renderer.ex | 21 +++- ex/lib/cantrip/cli/renderer.ex | 139 +++++++++++++------------- ex/lib/cantrip/code_medium.ex | 2 +- ex/lib/cantrip/entity_server.ex | 39 +++++++- ex/test/cli/renderer_test.exs | 79 ++++++++++----- ex/test/entity_server_stream_test.exs | 12 +-- ex/test/m23_streaming_test.exs | 25 ++--- 8 files changed, 232 insertions(+), 127 deletions(-) diff --git a/ex/lib/cantrip/acp/event_bridge.ex b/ex/lib/cantrip/acp/event_bridge.ex index f63b7e55..ae41c1bd 100644 --- a/ex/lib/cantrip/acp/event_bridge.ex +++ b/ex/lib/cantrip/acp/event_bridge.ex @@ -4,6 +4,8 @@ defmodule Cantrip.ACP.EventBridge do Spawned per-prompt as a lightweight process.

Finding 5 (call_entity isomorphism) tracked as grimoire#3. Fix 1 (HIGH): Enforce code medium contract. When a code-medium entity's LLM returns prose without an elixir tool call, surface as error observation instead of silently succeeding as a conversation turn. Non-elixir tool calls (used by conformance tests for call_entity) still processed normally. Removed stale :code field from llm.ex validate_response. Fix 2 (HIGH): Include tool_call_id in tool_result events. ACP bridge can now correlate tool_call with tool_call_update using matching IDs. Fix 3 (MEDIUM): Route text_delta through envelope. EntityServer wraps stream_to with a relay process that adds the event envelope to bare text_delta events from the LLM adapter. Removed bare-event fallback clauses from all three consumers — the envelope contract is now complete. Fix 4 (MEDIUM): Pass stream_to on subsequent ACP Familiar sends. The entity_pid path now passes opts (including stream_to) like the first-call path, so events stream on all turns, not just the first. Also: removed call_entity/call_entity_batch from Familiar gate list. The Familiar uses cantrip/cast/dispose for delegation — one blessed pattern. (Part of grimoire#3 but trivial to do now.) --- ex/lib/cantrip/acp/event_bridge.ex | 6 --- ex/lib/cantrip/acp/runtime/familiar.ex | 4 +- ex/lib/cantrip/cli/json_renderer.ex | 9 ---- ex/lib/cantrip/cli/renderer.ex | 6 --- ex/lib/cantrip/entity_server.ex | 59 ++++++++++++++++++++++---- ex/lib/cantrip/familiar.ex | 2 +- ex/lib/cantrip/llm.ex | 3 +- 7 files changed, 55 insertions(+), 34 deletions(-) diff --git a/ex/lib/cantrip/acp/event_bridge.ex b/ex/lib/cantrip/acp/event_bridge.ex index ae41c1bd..aa900c74 100644 --- a/ex/lib/cantrip/acp/event_bridge.ex +++ b/ex/lib/cantrip/acp/event_bridge.ex @@ -90,12 +90,6 @@ defmodule Cantrip.ACP.EventBridge do %ACP.ContentChunk{content: {:text, %ACP.TextContent{text: ""}}}}) end - # Bare events (text_delta from LLM adapter, no envelope) - defp translate_and_send(conn, session_id, {:text_delta, chunk}) when is_binary(chunk) do - notify(conn, session_id, - {:agent_thought_chunk, - %ACP.ContentChunk{content: {:text, %ACP.TextContent{text: chunk}}}}) - end defp translate_and_send(_conn, _session_id, _event), do: :ok diff --git a/ex/lib/cantrip/acp/runtime/familiar.ex b/ex/lib/cantrip/acp/runtime/familiar.ex index a81085da..5df2f74c 100644 --- a/ex/lib/cantrip/acp/runtime/familiar.ex +++ b/ex/lib/cantrip/acp/runtime/familiar.ex @@ -73,7 +73,9 @@ defmodule Cantrip.ACP.Runtime.Familiar do end def prompt(%{entity_pid: pid} = session, text) when is_pid(pid) and is_binary(text) do - case Cantrip.send(pid, text) do + opts = if session[:stream_to], do: [stream_to: session.stream_to], else: [] + + case Cantrip.send(pid, text, opts) do {:ok, result, next_cantrip, _loom, _meta} -> answer = normalize_answer(result) next_session = %{session | cantrip: next_cantrip} diff --git a/ex/lib/cantrip/cli/json_renderer.ex b/ex/lib/cantrip/cli/json_renderer.ex index f9f08294..149bcf53 100644 --- a/ex/lib/cantrip/cli/json_renderer.ex +++ b/ex/lib/cantrip/cli/json_renderer.ex @@ -30,15 +30,6 @@ defmodule Cantrip.CLI.JsonRenderer do {[json, "\n"], :stdout, state} end - # Bare events (text_delta from LLM adapter, backward compat) - def render_event(state, {type, data}) when is_atom(type) do - json = - %{type: Atom.to_string(type), data: serialize_data(data)} - |> Jason.encode!() - - {[json, "\n"], :stdout, state} - end - def render_event(state, _unknown), do: {"", :stdout, state} defp serialize_data(data) when is_map(data) do diff --git a/ex/lib/cantrip/cli/renderer.ex b/ex/lib/cantrip/cli/renderer.ex index 302e1654..ff1320f5 100644 --- a/ex/lib/cantrip/cli/renderer.ex +++ b/ex/lib/cantrip/cli/renderer.ex @@ -155,12 +155,6 @@ defmodule Cantrip.CLI.Renderer do # -- Suppressed / catch-all -- def render_event(state, {_, {:text, _}}), do: {"", :stderr, state} def render_event(state, {_, {:step_complete, _}}), do: {"", :stderr, state} - - # Fallback for bare events (text_delta from LLM adapter, backward compat) - def render_event(state, {type, _} = bare) when is_atom(type) do - render_event(state, {%{entity_id: nil, depth: 0, medium: :code}, bare}) - end - def render_event(state, _unknown), do: {"", :stderr, state} # ── Indentation ────────────────────────────────────────────────────── diff --git a/ex/lib/cantrip/entity_server.ex b/ex/lib/cantrip/entity_server.ex index 59f2ede7..08896d77 100644 --- a/ex/lib/cantrip/entity_server.ex +++ b/ex/lib/cantrip/entity_server.ex @@ -197,7 +197,7 @@ defmodule Cantrip.EntityServer do messages: messages, tools: tools, tool_choice: tool_choice_override || state.cantrip.identity.tool_choice, - stream_to: state.stream_to + stream_to: wrap_stream_to(state) } emit_event(state, {:message_start, %{turn: state.turns + 1}}) @@ -288,17 +288,30 @@ defmodule Cantrip.EntityServer do {%{content: content, code: code, tool_calls: tool_calls}, obs, result, terminated, next_state} else - # No code in tool call — emit content as text if present if is_binary(content) and content != "" do emit_event(state, {:text, content}) end - # Fall through to regular tool call handling - {observation, result, by_done} = - execute_gate_calls(state.cantrip.circle, tool_calls, state.entity_id) - - {%{content: content, tool_calls: tool_calls}, observation, result, by_done, - state.code_state} + if tool_calls != [] do + # Non-elixir tool calls in code medium — process them normally. + # (child entities in code circles may receive conversation-style tool calls) + {observation, result, by_done} = + execute_gate_calls(state.cantrip.circle, tool_calls, state.entity_id) + + {%{content: content, tool_calls: tool_calls}, observation, result, by_done, + state.code_state} + else + # No tool calls and no code — the model violated the medium contract. + # Surface as error observation so the entity can steer (CIRCLE-5). + error_msg = + "Code medium requires an elixir tool call.

A reviewable Solid V1 needs + the runtime spine to be clear and the test signal to be trustworthy; it does + not need us to polish every old example before the cutover lands. +- Doing now: full suite after Credo warning cleanup. +- Verified: full suite after Credo warning cleanup is green: + `407 tests, 0 failures`. +- Closed this loop: warning cleanup is done enough for Solid V1. Remaining + Credo output is non-blocking style/refactor work. +- Next slice: safe diagnostics and ACP lifetime checks.

The idea belongs in the plan, but not in Solid V1 + implementation. Removed that module and changed loom tests to pin only the + generic append/read event-log behavior. +- Verified: focused loom tests are green: `10 tests, 0 failures`. +- North star: this re-centers the branch on durable loom reality without + prematurely committing to artifact/evaluation/promotion APIs. +- Doing now: full suite and formatter after removing the V1.5 runtime surface. +- Verified: formatter still passes after removing the V1.5 runtime surface. +- Verified: full suite is green after that scope correction: + `409 tests, 0 failures`. +- Verified: `mix credo` still has no warnings or software-design findings. +- Current shape: `EntityServer` is down to 647 lines, `Circle` is down to 107 + lines, and the extracted runtime spine is now visible in `Turn`, `Event`, + `Loom`, `Medium`, `Gate.Executor`, `ProviderCall`, and `WardPolicy`. +- Next: write a concise PR draft that explains the Solid V1 spine, verification + status, and deliberately deferred V1.5/V2 work. This is the handoff artifact + for reviewability, not a new runtime feature. +- Doing now: PR draft. +- Done: added `CUTOVER_PR_DRAFT.md` with a Solid V1 summary, runtime/protocol + fix list, verification status, and explicit deferred V1.5/V2 scope. +- Verified: formatter check passes for progress/spike/PR draft docs, and + `git diff --check` still passes. +- Next: the branch is locally coherent enough for a review pass. Remaining work + is either PR mechanics (commit/push/open PR) or a final source-level review + of the changed runtime modules for subtle behavioral risks. +- Continuing autonomously: started source-level review of the runtime spine. +- Reviewed and corrected course: a suspected continuation-sequence bug was + actually a scope invariant. Turn `sequence` remains local to the entity/subtree + being projected into the loom: parent turns can be sequence 1/2 while a grafted + child turn keeps its own sequence 1. The boundary test now states this instead + of forcing global turn sequences. +- Doing now: focused conformance/runtime verification after restating that + invariant. +- Verified: focused conformance/runtime/composition tests are green: + `62 tests, 0 failures`; formatter check passed. +- Next: full suite after the sequence-scope review. +- Doing now: full suite. +- Verified: full suite after the sequence-scope review is green: + `409 tests, 0 failures`. +- Verified: `mix compile --warnings-as-errors` still passes. +- Next: continue source-level review on medium/gate/provider boundaries for + Solid V1 behavioral traps. +- Doing now: inspect `Gate.Executor`, medium adapters, and `ProviderCall`. +- Found and fixed: provider retries were still allowed for streaming requests. + Since streamed output may already have reached subscribers, retrying can replay + unsafe partial output. `ProviderCall` now disables retry when the request has + an event emitter, and the boundary test pins single-attempt behavior. +- Verified: focused provider/production/streaming tests are green: + `41 tests, 0 failures`; formatter check passed. +- Doing now: full suite after streaming-retry guard. +- Verified: full suite after streaming-retry guard is green: + `410 tests, 0 failures`. +- Verified: `mix compile --warnings-as-errors` passes. +- Next: rerun formatter/Credo/diff checks, then update PR draft with the + streaming-retry safety fix and current test count. +- Doing now: final hygiene pass. +- Verified: `mix format --check-formatted` passes. +- Verified: `git diff --check` passes. +- Verified: `mix credo` still has no warnings or software-design findings; + remaining output is non-blocking readability/refactor advice. +- Done: updated `CUTOVER_PR_DRAFT.md` with the streaming-retry guard and current + `410 tests, 0 failures` status. +- Next: continue source-level review on remaining protocol/diagnostic edges or + prepare PR mechanics when requested. +- Heartbeat north star: Solid V1 still means ordered event reality, supervised + BEAM lifetimes, explicit medium/gate/ward boundaries, stable ACP/CLI, and no + V1.5 evolution APIs. +- Found and fixed: ACP direct-answer fallback was still available for streaming + sessions when the bridge returned `:no_answer`. That is useful for + synchronous runtimes, but unsafe for streaming runtimes because bridge flush + can race with final-response delivery. Runtime sessions that stream now mark + `streaming?: true`, and AgentHandler only direct-sends `:no_answer` for + non-streaming sessions. +- Verified: focused ACP/Familiar tests are green: `40 tests, 0 failures`; + formatting was applied to touched files. +- Doing now: full suite after the streaming fallback guard. +- Verified: full suite after the ACP streaming fallback guard is green: + `411 tests, 0 failures`. +- Found and fixed during hygiene: a few easy Credo readability issues were + still in the branch (`with` forms that wanted `case`, a test-support + moduledoc, and two tiny refactors around diagnostics/feedback formatting). + This is not architectural work, but it makes the PR quieter for reviewers. +- Verified: focused examples/runtime/ACP diagnostics tests are green: + `87 tests, 0 failures` across the focused runs. +- Verified: `mix compile --warnings-as-errors` passes after those readability + edits. +- Verified: `mix credo` now reports no warnings, readability, or software-design + findings; only non-blocking refactor suggestions remain. +- Done: updated `CUTOVER_PR_DRAFT.md` with the ACP streaming-session fallback + guard and current `411 tests, 0 failures` status. +- Next: rerun final full-suite/formatter/diff hygiene after the tiny test + warning cleanup, then decide whether the next loop should be PR mechanics or + one more source-level pass over protocol comments/docs. +- Verified: final formatter check passes. +- Verified: final diff whitespace check passes. +- Verified: final compile hygiene passes with `--warnings-as-errors`. +- Verified: final full suite is green and warning-free in the touched test path: + `411 tests, 0 failures`. +- Current PR size after the cutover is `65 files changed, 1926 insertions(+), + 2117 deletions(-)`, mostly because the old `Circle`/`EntityServer` control + mass moved into named runtime boundary modules. +- Next: the Solid V1 slice is reviewable locally. The highest-value next action + is PR mechanics (stage/commit/push/open a draft PR) unless another heartbeat + asks for one more code-level sweep first. +- Heartbeat north star: keep Solid V1 grounded in one durable event reality and + supervised runtime boundaries; do not let old "single sender" language + overstate what the ACP bridge guarantees. +- Found and fixed: `EventBridge` moduledoc still claimed a pure single-sender + ordering model. The implementation is safer and more precise now: streaming + runtimes route final answers through the bridge, while AgentHandler direct + fallback is only for non-streaming sessions or dead bridges.

This is CIRCLE-5 / LOOP-7 defense in depth: a malformed gate call must be data the entity can reason about, never a function_clause exception that escapes the gate boundary. The empty-pattern case in `search` gets the same treatment. `gate_root/1` also now reads from either `:dependencies` (per CIRCLE-10 vocabulary) or the legacy top-level `:root` field that early gate configs used. `search` returns a list of `%{path, line, text}` match maps instead of a newline-joined string, consistent with `list_dir` returning a list. Code-medium entities can now `Enum.map` / `Enum.uniq_by` over results directly; the prior string return forced string parsing in the sandbox and caused a `BitString is not Enumerable` error in production Zed traces. * SpawnFn: inherit parent dependencies into bare child gates (CIRCLE-10) SPEC §5.1 names the SpawnFn as the runtime hook that "wires up the gate dependencies" when a parent proposes a child circle. CIRCLE-10 requires gate dependencies to be "configured at circle construction time, not at gate invocation time." The Familiar's whole pattern depends on this. A parent code-medium entity writes `cantrip.(%{circle: %{gates: ["read_file", "done"]}})`, and the runtime must turn that bare gate name into a fully wired gate — description, JSON schema, sandbox root — before the child's medium presents it to its LLM. Previously the runtime fell back to `%{name: name}` and the child saw an empty schema with no root. `Cantrip.EntityServer.maybe_call_child` now resolves bare gate names through `Gate.spec/1` and merges in any dependency keys the spec declares as required, drawn from the parent's gate map. The parent's existing gates can carry deps either under `:dependencies` (the CIRCLE-10 vocabulary) or at the top-level `:root` (the Familiar.new convention); both feed the same merge. Tests pin three contracts: a code-medium child with bare `read_file` inherits the sandbox and reads successfully; a child whose LLM forgets `path` produces a structured error observation the parent can rescue; the loom records `is_error: true` on the malformed child invocation so the parent can introspect. * Examples 15 / 16 and behavior ladder L4 / L5 for Familiar+filesystem children PATTERNS.md documents 16 progression patterns; the `Cantrip.Examples` catalog had only 12 actual implementations. Patterns 15 and 16 — the two that exercise Familiar's defining capability of spawning filesystem-aware children — lived in the doc but not in code. Without scripted versions, the production Familiar's pattern-16 contract was unverified outside of live LLM use. `run_15` (research-style fanout) constructs the Familiar with a sandbox, has it `list_dir` the markdown facts, spawns three file-reading children via `cast_batch`, and synthesizes their results. `run_16` (Familiar coordinator) summons the production Familiar, delegates a real file read across two sends with persistent JSONL loom, and recalls prior memory in the second send. Both are FakeLLM-scripted so CI can pin the substrate end-to-end without live LLM costs. `familiar_behavior_test.exs` gains L4 (single child reads a file in the parent's sandbox) and L5 (parallel fanout: two children, results in request order). These are regression anchors for the Zed-trace failure modes that motivated the SpawnFn fix. `examples_test.exs` updates the `ids/0` assertion and the scripted- mode / real-mode loops to cover 15 and 16. * Familiar prompt: teach child medium choice purposefully The prior prompt listed `:conversation`, `:code`, `:bash` as peer options without saying when each applies, and showed the whole-task example with `:code`. That left the LLM to guess — and Zed traces showed it sometimes picking `:conversation` for tasks that would compose better in `:code`. The new prompt: - Declares `:code` the default with a one-line example. - Names `:conversation` for narrow well-typed tool calls with a one-line example. - Names `:bash` for shell-natural tasks with a one-line example. - States explicitly that children inherit the parent's sandbox root for filesystem gates, so parents don't need to thread paths or roots through child configs. - Updates the footguns section: `search` returns a list of maps (matching the new substrate); a failed gate is an observation, not a crash (matching the new validate_gate_path contract). Prompt content is iterative; this is the baseline that matches the substrate's actual contract. Optimization with live-LLM evals stays a separate concern from the substrate changes in earlier commits. * Fix theater in examples 15/16; add real-LLM integration tests The scripted-mode example tests asserted `{:ok, _, _, _, _}` (shape) not value content. That hid two real bugs in the freshly-added patterns: * `run_15`'s child code referenced `intent` as an unbound variable, crashing the child. FakeLLM's default `%{content: "ok"}` filled the empty slot, and the parent stitched "ok | ok | ok" into a done() answer. Tests passed; behavior was theater. * `run_16` tried to recall `lines` across two sends by setting it in the same turn it called done() on. Code-medium's done-throw returns the input binding, not the post-eval binding, so the assignment was lost. FakeLLM ran out of scripted responses on send 2 and returned default `%{content: "ok"}`. Same shape, no recall. Fixes: * `run_15` now scripts each child reader with its file path baked in (FakeLLM can't read its own intent text; real LLMs can). The parent's prompt has each child read the file in its intent so the same code path works in real-LLM mode without changes. * `run_16` splits send 1 into two turns (set `lines` in turn 1, call done in turn 2), mirroring the `run_11` pattern that pins ENTITY-5 / MEDIUM-3 binding persistence. Send 2 reads `lines` cleanly from the persisted binding. * `examples_test.exs` gains content-level assertions for 15 and 16 (parent's result contains the actual fact strings; child read observations are present and successful; loom grafts the child subtrees). Two regression tests verify both examples use `Cantrip.Familiar.new` rather than constructing a parallel coordinator code path — keeping examples honest about which abstraction they exercise. * Renames pattern 12's catalog title from "Familiar: Child Cantrips Through Code" to "Persistent Coordinator: Direct call_entity Delegation". `run_12` builds its coordinator with `Cantrip.new` and uses raw `call_entity`, not the `cantrip / cast / dispose` Familiar pattern. The old title implied otherwise. Coherent separation: 12 demonstrates manual delegation; 15 and 16 demonstrate the production Familiar. * `test/familiar_real_llm_integration_test.exs` adds two real-LLM integration tests tagged `:integration` and gated by `Cantrip.Test.RealLLMEnv.enabled?()` (the same env-var pattern m9 / m10 use). They exercise the production `Cantrip.Familiar.new` end-to-end: a real LLM delegating a single read, and fanning out reads in parallel via cast_batch. They short-circuit to `:ok` in default CI; opt in with `RUN_REAL_LLM_TESTS=1` plus CANTRIP_* env. * Code medium: preserve bindings across the done-call boundary (MEDIUM-3) `done.(x)` throws `{:cantrip_done, ...}` to terminate the turn. The old eval handled that by catching the throw and returning the *input* binding — which dropped every assignment made earlier in the same turn. That broke the natural "compute then done" pattern across multi-send entities: by the next send, the computed value was gone. The bite radius was real, not theoretical. For pattern-16 Familiar coordinators (where a single intent should naturally execute as one turn that computes and dones), users would write: lines = cast.(reader, "Read todo.md") done.(lines) …and on the next send, `lines` would be undefined. The workaround in `run_11` (split into two turns: one assigns, one calls done) is brittle and unintuitive — and it's not how the system prompt's own whole-task example is written. Fix: evaluate top-level statements one at a time. The catch in each recursive frame returns the binding accumulated by *previous* statements in the same block, preserving anything assigned before the done-calling statement. - The done-throw still terminates the turn (unchanged). - All prior-statement assignments are preserved (new). - A turn with only `done.(x)` still works (no regression). - Multiple assignments before done all persist. `run_16` now uses the natural single-turn-per-send shape — set `lines`, call done — exactly as a real user would write it. The prior split-turn workaround is gone. Three new tests in `code_medium_ergonomics_test.exs` pin the contract: single-assignment-then-done preserves the binding across a turn boundary; multiple sequential assignments all persist; bare done without prior assignments still works. * Real-LLM integration: pin the Zed-trace scenarios end-to-end The previously-added integration tests gated on RUN_REAL_LLM_TESTS were focused — single-read and parallel-read with explicit file names. Verified passing against a real LLM (4 tests, ~19s end to end). But they don't match the original failure shape: the Zed traces in scratch/familiar-run-00{1,2}.md were open-ended exploration where the user's intent was conversational ("check out the new harness, what do you think?") and the Familiar had to figure out what to do. Two new trials added, matching those scenarios: * Open-ended exploration with the literal prompt from the original trace. Asserts the Familiar reaches done() and produces a non-empty answer, AND that no observation in the loom surfaces a `function_clause` or `IO.chardata_to_string` string — those were the original crash signatures that escaped the gate boundary as text. * Recovery from a child LLM omitting the `path` argument: the parent delegates a read with an underspecified intent ("there's a file in this directory, find and read it"), which some LLM choices route through a read_file call without `path`. Pre-fix that crashed the child with function_clause; post-fix it must surface as a structured is_error observation. The test asserts the loom is free of crash text. Also fixes a brittle assertion in the prior parallel-fanout test: LLMs sometimes call `read_file.("alpha.txt")` (bare string) instead of `read_file.(%{path: "alpha.txt"})` (map). Both shapes are equivalent at the gate boundary; the test now normalizes when introspecting arguments from the loom. All four real-LLM tests pass against the live model. Combined with the 451 FakeLLM-suite tests, the branch is now verified at both layers: deterministic substrate contracts in CI, and live-LLM end-to-end against the actual failure scenarios the work was motivated by. * Familiar prompt: teach the paradigm, don't instruct the employee The prior prompt was crisp on grammar (gates, syntax) and footguns but thin on the paradigm it claims. It opened with a job description ("you are a persistent entity that observes a codebase and orchestrates work") and split work into pre-classified "casual" vs "real" buckets. Reading the cantrip bibliography sharpened what's missing: the operative names (cantrip, circle, ward, gate, loom, familiar) are load-bearing per the author's framing — "precise naming is itself part of practice." Wards aren't behavioral restrictions; they're capability containment (Miller/Yee/Shapiro). Code is the medium, gates are native callables (Cheng/Wang). The loom is a multiverse interface and a training substrate, not a log (Moire/cyborgism). And the whole stance per RLM/Zhang and the deepfates RLM essay: the entity isn't a chatbot with tools; it's a program of inquiry written in code, and sub-calls are how it thinks harder, not just how it delegates work. The rewrite leans into the paradigm: - Opens by orienting the entity to the world it inhabits, not by assigning it a job. "You are a Familiar — a long-lived companion spirit attached to this codebase. You arrive into each session already carrying the loom you've been weaving across all prior castings." - Names operatively. Identity is "who they are for the duration of the casting." Gates are "what they can do." Wards are "what they cannot." Type is "the medium of their mind." - Treats `cantrip.()` as summoning (drawing a circle, naming, listing capabilities), `cast` as speaking intent into the circle, `dispose` as letting the helper disperse. Same code semantics, but the metaphor does the explaining. - Removes the casual/real pre-classification. Replaces with "depth follows the question." Trusts the model. - Blesses introspection explicitly: `binding() |> Keyword.keys()` to see what's bound; `loom.turns` to walk prior work. The interactive trial showed an LLM defensively guarding variable access when it could have just used the variable — the prompt now removes that hesitation. - Folds the footguns into "the grain of this medium" — properties of the substrate, not rules to obey. The interactive trial against a real LLM (Claude) produced substantively richer engagement than the prior prompt on the same input: "inhabiting a small live workshop where filesystem reads, helper casts, and synthesis are all the same kind of act... The closest sensation is programming the investigation while simultaneously being the investigator." That phrase isn't in the prompt; it's the paradigm landing. `familiar_test` updates the assertion to match the new vocabulary (helper, cantrip, gates, wards, loom) without losing the contract that the prompt teaches the helper-summoning paradigm. * Loom: actually persist and rehydrate substance across sessions Pattern 16 in the catalog is named "Persistent Loom + Filesystem Children." Investigating found the persistence half had never been end-to-end built. Two distinct holes, neither covered by any test in the repo's history: Hole 1 — silent encoding failures dropped substance turns. The JSONL backend wraps `Jason.encode!` in a rescue that catches Protocol.UndefinedError and returns `{:error, ...}`. The caller in `Cantrip.Loom.append_event/2` ignores the error and keeps the in-memory loom going. The visible symptom: a JSONL file with only `continuation: true` markers. The proximate cause is tuples in the turn tree, not just functions. Every code-medium turn's `code_state.binding` is a keyword list, which is a list of 2-tuples. `done({:ok, x})` is a tuple. Custom structs without Jason.Encoder protocols. All silently dropped. This was masked, before the MEDIUM-3 commit (ee2c532) earlier in this branch, by the fact that bindings were always empty: the done-throw returned the input binding, dropping any in-turn assignments. So all persisted turns had `code_state: %{binding: []}` and encoded fine. Once the binding actually carries substance — which is what makes pattern 16 work — this latent encoding bug becomes the dominant failure mode. Hole 2 — no backend has ever loaded on init. `Loom.new/2` always returns `%Loom{events: [], turns: [], ...}` regardless of storage. The JSONL/DETS/Mnesia backends only know how to write. A Familiar re-summoned against an existing `loom_path` starts blind. Fixes: - `Cantrip.Loom.Storage` gains an optional `load/1` callback that returns `{:ok, %{events: [...], turns: [...]}}` — the storage behaviour now describes both write and read paths. - `Cantrip.Loom.Storage.Jsonl` defensively sanitizes turn values before encoding (tuples → lists; functions/PIDs/refs/ports → inspect strings; structs without Encoders → maps with __struct__ preserved; primitives untouched). The on-disk JSONL is a projection of in-memory state, not a perfect round-trip — but every turn reaches the file regardless of inner shape. - `Cantrip.Loom.Storage.Jsonl.load/1` reads existing JSONL, classifies by event type, and atomizes the well-known turn / observation field names (using a fixed allowlist; never `String.to_atom` on arbitrary user-controlled keys). - `Cantrip.Loom.new/2` calls `load/1` after `init/1` and populates events/turns from the result. Tests: - `test/loom_jsonl_persistence_test.exs` pins five contracts: list-of-maps observations persist; populated bindings persist (the case the MEDIUM-3 fix exposed); tuple-shaped results persist; cross-session recall via a fresh Loom on the same path restores prior turns; full executed-turn including grafted child subtree round-trips. - `familiar_behavior_test` gains L9: a Familiar summoned, cast, and re-summoned against the same loom_path resumes with its prior turn visible — including substantive observation and gate calls. - Integration tests now stringify via `Cantrip.ACP.EventBridge.stringify/1` rather than `to_string/1`, matching the actual production path (the bridge handles any shape; the test was string-biased from when the prior prompt produced only string answers). All four real-LLM integration tests verified passing against a live model (~21s end-to-end). * Diagnostics: --diagnostics now works in REPL and single-shot modes The Solid V1 spike said: "Treat ACP/Zed/CLI as live views over the same ordered runtime events." But `--diagnostics` lived inside `run_acp/1` only, so attaching a remsh inspector required running in ACP mode. The production REPL surface — the one a developer drives interactively — had no path to introspect a stuck Familiar. `mix cantrip.familiar --diagnostics` now starts the distributed Erlang node regardless of which mode follows (REPL, single-shot, or ACP). The remsh / Cantrip.ACP.Diagnostics.dump() affordance is uniform across surfaces. * Loom: round-trip Elixir terms faithfully (tagged tuples/atoms; binding-key promotion) Earlier in this branch the loom JSONL silently dropped substance turns because non-encodable Elixir terms (tuples, functions) failed Jason serialization. The first fix (`8b2db70...`-adjacent commit, sanitization) made every turn reach disk by converting tuples to lists, atoms to strings, functions to inspect strings. That kept turns visible but made round-trip lossy: bindings rehydrated as nested lists of strings, not as the keyword lists of {atom, value} tuples they were on the write side. For pattern 16's actual promise — an entity resuming sees prior variables as the same kinds of values it would have seen in-session — that's not enough. So this finishes the rehydration: - Tuples and atoms are now *tagged* on write (`%{"__t__" => [...]}`, `%{"__a__" => "name"}`) rather than lossily flattened. - `from_jsonable/1` reverses the tagging on load. Atom restoration is bounded by `String.to_existing_atom` to avoid VM atom-table pollution from arbitrary on-disk strings. - `atomize_code_state/1` and `promote_binding_keys/1` close the last asymmetry: a keyword-list binding entry's first element is structurally an atom by Elixir's spec, and in that bounded position we promote strings to atoms via `String.to_atom` so a cross-session entity can `Keyword.get(binding, :name)` against its prior variable names. The atoms come from the entity's own code, not adversarial input. - `atomize_utterance/1` and `atomize_metadata/1` close the inner-key asymmetry on the other turn fields the entity touches. Verified end-to-end with a real LLM across two distinct BEAM processes (tmux summon → cast → kill → re-summon → recall): session 2 read `loom.turns`, walked `code_state.binding`, did `Keyword.get(binding, :fruit)` and got back the literal string session 1 wrote, by atom key, same as it would have within a single session. Functions, PIDs, refs, and ports remain unrestorable — they survive as opaque `%{"__inspect__" => "..."}` placeholders. That's the honest limit: live process state can't be reconstituted from disk. Test updates: - `loom_jsonl_persistence_test`: the "known limitation" test inverts to a "round-trips faithfully" assertion; the function-in-binding test now asserts the function entry survives as a tuple `{:somefn, opaque}` rather than being dropped. - `m3_loom_storage_test`: the generic-event test expects the new on-disk tagged shape AND verifies that production `Loom.new` rehydration restores the atom faithfully. 472 tests, 0 failures. * Mix task: extract parse_args/1 as pure routing function + pin diagnostics symmetry `mix cantrip.familiar` now has a regression anchor for the mode-agnostic `--diagnostics` behavior. The previous commit (`70f6cdf`) moved diagnostic-node setup out of the ACP-only branch so REPL and single-shot modes also get the remsh affordance, but had no test. Adding one required teasing routing out of the impure `Mix.Task.run/1` into a pure `parse_args/1` that returns a tagged shape (`{:help, _}` | `{:acp, ctx}` | `{:repl, ctx}` where `ctx` carries diagnostics-as-data). Ten routing tests cover: no flags → repl/no-intent/no-diagnostics; positional intent → repl/single-shot; `--acp`; `--help` precedence; `--diagnostics` in REPL / single-shot / ACP / not-at-all; loom-path and max-turns pass-through. Together with `70f6cdf`, this closes the spike's ask that ACP / REPL / CLI be "live views over the same ordered runtime events" — the diagnostic node is part of that runtime, not an ACP concern. * Format: blank line after stringify call in real-LLM integration test * Loom JSONL: preserve explicit nils; document atom-keyed-map round-trip limit Two refinements to the JSONL round-trip path after running it through a StreamData property generator: 1. `atomize_turn`, `atomize_observation`, `atomize_code_state`, `atomize_utterance`, and `atomize_metadata` now use `Map.has_key?/2` instead of testing whether `Map.get/2` returned `nil`. The previous logic silently dropped fields whose persisted value was explicitly `nil` — e.g., a turn's `utterance.content` being `nil` when the LLM used only tool_calls — making the restored shape differ subtly from the in-session shape. Now explicit nils round-trip. 2. The property test pins the round-trip claim with bounded scope: any turn-shaped attrs whose nested user values are not atom-keyed maps round-trip equal. Atom-keyed maps INSIDE user values (e.g., the entity returns `done.(%{token: "mango"})` and the map has atom keys) round-trip with string keys cross-session. The workaround is bounded — entities use `m["key"]` for cross-session reads of arbitrary user maps — and the trade-off vs. invasively tagging every map's keys is documented in `Cantrip.Loom`'s moduledoc. Atom keys at structural positions (turn fields, observation fields, `code_state.binding` keyword-list entries) DO round-trip via the existing atomize/promote paths. The bounded limit is specifically for arbitrary user-provided maps inside results. `stream_data ~> 1.1` added as a test-only dep. * Loom backend symmetry: DETS and Mnesia get load/1 too JSONL's load/1 implementation made pattern 16's "persistent loom" contract real for that one backend. The DETS and Mnesia backends — both shipped, both selectable via `loom_storage: {:dets, path}` or `loom_storage: {:mnesia, opts}` — were still write-only. The asymmetry would have been a hidden footgun: a user picking DETS for durability would silently lose cross-session recall. Both native-term backends now implement `load/1` symmetrically: they read their stored events, classify by type, and return the same `{:ok, %{events: ..., turns: ...}}` shape `Loom.new` expects. No tag-based restoration is needed because DETS and Mnesia preserve Erlang terms natively through `term_to_binary` / native term storage; atoms and tuples come back as-is. `loom_backend_symmetry_test` pins three things: - DETS round-trips a substantive turn through write → close → reopen. - Mnesia does the same (skipping cleanly when mnesia isn't available on the host, so CI without disk-mode mnesia still works). - All three production backends export `load/1` — the asymmetry the Solid V1 spike warned about ("ACP/REPL/CLI as live views over the same ordered runtime events") no longer applies at the storage layer either. * Zed-trace replay: drive the original failure sessions against the live LLM The unit and integration tests pin the substrate's behavior at every boundary. This adds the most direct test of the production claim: the *exact same user prompts that broke the original Zed sessions* (`scratch/familiar-run-001.md`, `scratch/familiar-run-002.md`) now flow through the Familiar end-to-end and the user gets a substantive answer each turn. Three scenarios, gated by `RUN_REAL_LLM_TESTS=1`: 1. run-002's 8-prompt conversation replayed in sequence against one summoned Familiar. Each `Cantrip.send/2` must terminate and the ACP bridge must convey the result as non-trivial text. 2. run-001's first three prompts replayed similarly. 3. A summon → 2-turn-conversation → kill → re-summon-against-same-loom cycle, with the fresh entity asserting substance via a recall prompt. The "did the substrate crash" question is the wrong layer for this test — it's covered by `gate_validation_test`, `loom_jsonl_persistence_test`, `spawn_fn_test`, and the code-medium tests at the unit-test level. The integration question this test answers is "does the user get coherent output?" — and `meta.terminated == true` plus a non-empty bridge-stringified answer is the right assertion surface for that. (An earlier draft tried to match historical crash-text shapes in observation results via regex. That approach false-positived on the entity reading its own test files, which contain the crash patterns as documentation. Pattern-matching observation content is the wrong tool; structural assertions on cast outcomes are right.) Verified passing against a live model: run-002 ~212s (8 turns), run-001 ~12s (3 turns), rehydrate scenario ~18s. * Real-LLM multi-seed: pin ≥2/3 pass rate over natural model variance The single-shot real-LLM integration tests (`familiar_real_llm_integration_test`) verify the production path passes against a live model — but at n=1 per scenario, that's "the substrate worked once," not "the substrate works reliably." LLMs are probabilistic; the substrate's job is to be sturdy across natural completion variance. Three scenarios, each repeated 3 times, asserting ≥2/3 passes: - Single-child file read (delegating to a code-medium child) - Parallel `cast_batch` fanout over two file-reader children - Open-ended exploration ("check out the new harness") The threshold (one unlucky completion is OK; systemic failure is not) makes the test honest about probabilistic systems while still catching substrate regressions. A flaky pass rate (1/3 or 0/3) would surface a real fragility. Verified passing against a live model: 9 scenarios run, all 3 tests 3/3, ~90s total wall clock. Gated by `RUN_REAL_LLM_TESTS=1`. Default CI is unaffected. * Add PR_DRAFT.md: production-grade Familiar thesis A thesis-style PR description for the branch — not a victory lap but an honest accounting of what's claimed, what's verified, what's deferred, and the layer of evidence backing each claim. Frames the work as making the implementation honor the framework's claims (loom as canonical record, ACP/REPL/CLI as projections of one runtime, operative naming doing real work), grounds substantive changes in the cantrip bibliography, and documents the one bounded limit (atom-keyed maps inside user values don't round-trip cross-session) along with its workaround. Marks the prompt-level claim explicitly as iterative ("trialed against one model in one conversation; multi-seed prompt eval is its own engagement") so reviewers can distinguish what's substrate-verified from what's still in development. * Familiar prompt v2: program-in-computer paradigm + bridge readability The prior Familiar prompt taught the grammar of code medium (list_dir, cast, variables, done) and a "companion spirit attached to this codebase" voice. After working through the cantrip bibliography (RLM essay, Cheng's shared program state, the agent-harness essay's composable-vs-sequential distinction), redrafting the prompt to land the actual paradigm: - Opens flat and constitutive: "you are a kind of program that lives in a computer and uses language to act on everything within it." No mysticism, no codebase-narrowing. The human is named as one of the functions in the environment, reached via done.(value). - Children are written as fellow entities with their own constitutive identities, not thin task-workers. The drafted child identity is an "analyst entity" with a stated attentional stance, not a one-shot file-reader. The prompt explicitly notes that the way the parent writes child identities propagates downstream through the recursion. - Composition section shows code + cast + variables interleaved in a single statement (Cheng's "shared program state" texture) rather than the prior staged-pipeline shape. - Names the active inference loop constitutively ("you operate as"), not permissively ("you have permission to"). - Recall through binding() / loom.turns named as the normal recovery move, not an exotic introspection. Bridge changes: - EventBridge.stringify/1 renders maps and lists as readable text ("key: value" lines, joined sensibly) instead of inspect-form. Bridge content feeds the user; raw Elixir glyphs are wrong shape. Never raises — falls back to inspect for opaque values. - ACP runtime familiar drops the per-prompt "Start by listing the directory to orient yourself" appendix that was poisoning every response into list_dir + dump. * Substrate pass: SPEC conformance for list_dir, PROD-8 redaction, real folding Three substrate gaps surfaced by interactively driving the Familiar against its own codebase and re-reading SPEC.md with eyes open. 1. list_dir shape (SPEC §1.7 conformance) The example at SPEC §1.7 line 209 pins list_dir's result as `["a.txt", "b.txt", "c.txt"]` — plain bare names. The implementation was appending " (file)" / " (dir)" display annotations to each entry, which broke every entity's `Enum.member?(entries, "mix.exs")` and `String.ends_with?(&1, ".md")` check. Three turns of an interactive session collapsed onto this papercut. Annotation stripped; the gate returns bare names. Tests and the run_15 example updated. 2. PROD-8: credential redaction at the gate observation boundary The substrate had no content filter on read_file or any other gate. Driving the Familiar against a real cwd produced a child reader that picked the first file with the (file) suffix — .env — and dumped live API keys into the session. New module Cantrip.Redact applies pattern-based redaction to every gate observation result before it reaches the entity: sk-*, sk-ant-*, AIza*, AKIA*/ASIA*, Bearer , and generic env-style assignments to variables named *KEY / *SECRET / *TOKEN / *PASSWORD. Redaction is recursive over strings, lists, and maps so list_dir / search results stay safe even if a filename or matched line carries a secret. Conservative by design — false positives preferred to leaks. Idempotent and pass-through for non-binaries. 3. Real folding (§6.8 + PROD-4 + LOOM-5 + LOOM-6) The prior fold_messages was conformance theater: a `trigger_after_turns` turn-count knob that defaulted to nothing on every cantrip, and when it fired just replaced folded turns with a placeholder string. PROD-4 says folding MUST trigger automatically when context approaches the LLM's limit; §6.8 says the substance of folded turns is integrated into the entity's reachable state, not dropped. New module Cantrip.Folding: - should_fold?/2 triggers on approximate prompt size against a configurable threshold (default 100K tokens, ~80% of a 128K window). Approximation: bytes ÷ 4 — overcounts for code, fine. - fold/3 partitions into identity + intent + recent tail, calls the cantrip's own LLM with a focused summarization prompt over the middle, and replaces the middle with one `[Folded: turns 1-N]\n` system message. Identity untouched (LOOM-6). Loom never written to (LOOM-5). - LLM failure during summarization falls back to a deterministic marker so the loop continues — full turns remain in the loom for later forensics. - The marker-only branch fires even when the body is shorter than the recent-keep window, so explicit fold calls always announce themselves (the legacy turn-count trigger relies on this). Cantrip.Turn.prepare_request wires both triggers (size-based and the legacy turn-count config) so existing tests pinning the old behavior continue to pass. 489 tests + 2 properties, format / warnings-as-errors clean. * Prompt v3 + recall binding: speech-through-done, unique cast naming, safe cross-turn lookup Driving the Familiar interactively against the substrate-pass branch surfaced three things that all traced back to the prompt + one missing substrate affordance: 1. Voice degradation through the recursion The parent's prompt produced voice on its own turns, but when it drafted a child's identity it closed with "Return a concise but vivid report **via done()**." The child read "via done()" as "compute a structured return for done()" and handed back `inspect(report_data, ...)`. The upstream cause was the prompt's own example child identity using the same mechanical closing. The example child identity now closes with: "Speak your read of it. When you call done, the prose you pass is the answer; you are speaking through done, not computing a value for it." Speech-not-data. The parent now patterns on this when writing children. 2. Variable name collision on `result` Every cast in the prompt examples was `result = cast.(...)`. The entity followed that — every cast reused `result`, each one overwriting the prior. Asked to recall an earlier cast result, the entity could only ever surface the most recent. Casts in the examples are renamed to say what they are: `spec_reading = cast.(analyst, ...)`, `chapter_readings = cast_batch.(...)`, `doc_verdicts = list_dir.(...) |> Enum.map(...)`. The prompt now states explicitly: bind what comes back to a name that says what it is, because that name is the only handle later. 3. `recall.(name, default)` binding The prompt teaches `binding() |> Keyword.keys()`. The obvious follow-up is `if Keyword.has_key?(binding(), :x), do: x` — and Elixir rejects it at compile time because `:x` is lexically resolved before any runtime check fires. An entity reaching for this pattern wastes 2-3 turns hitting the wall. `Cantrip.CodeMedium` (and `Cantrip.CodeMedium.DuneSandbox`) now bind: recall.(:spec_reading, "I don't have that bound yet.") The name is a symbol passed to a function, not a lexical reference. Looks up against the binding snapshot at the start of the eval (the prior-turn persisted bindings). Accepts atom or string; strings convert via `to_existing_atom` so the atom table doesn't grow on misses. The prompt teaches it as the safe defensive pattern for cross-turn recall, alongside `binding() |> Keyword.keys()` for inspection and `loom.turns` for walking history. 4. Honest framing on filesystem confinement The prior PR_DRAFT framed CIRCLE-6 as "may be hollow at the medium layer" because a child given `gates: ["list_dir", "search", "done"]` freely used `File.read!`. That framing was wrong — gates aren't an allow-list at the medium level; they're named, dependency-injected operations exposed to the entity's prompt. Code medium intentionally gives the entity full Elixir. The actual shape: default code medium has unrestricted `File.*`; the `:dune` sandbox ward exists and does restrict it, but doesn't currently expose the high-level `cantrip/cast/cast_batch/dispose` closures the Familiar's prompt teaches. So `:dune` isn't a usable production posture for the Familiar yet. That's the named next piece — not a "follow-up," the actual concrete thing to do next. PR_DRAFT_SUBSTRATE.md rewritten to reflect this honestly: the deferred section is gone; each item is either fixed in this commit or stated as a named concrete next piece. 493 tests + 2 properties green; format / warnings-as-errors clean. * Strip edge hacks; rewrite prompt around medium-selection-by-task The prior commit (prompt v3 + recall binding) addressed symptoms with substrate workarounds and prompt mimicry. Pulled out. Removed ------- - `recall.(name, default)` binding from `Cantrip.CodeMedium` and `Cantrip.CodeMedium.DuneSandbox`. It was working around an LLM behavior (guessing variable names instead of reading its own conversation context) rather than fixing it. The defensive lookup helper made the surface bigger without engaging the underlying pattern. - The `spec_reading` and `chapter_readings` example names baked into the prompt. The entity was pattern-matching the example name verbatim instead of learning that names should describe what they hold. Mimicry, not understanding. - The "speech-through-done" closing language in the example child identity. Interactive testing showed it didn't propagate: a child given a synthesis task in code medium still wrote a keyword- classifier with pre-canned strings, because code medium pulls the LLM toward "compute the answer" regardless of the closing instruction. - The corresponding 4 test cases in code_medium_ergonomics_test. Replaced with ------------- A medium-selection-by-task section in the spawn area of the prompt. The substantive move: teach the entity to pick the right medium for each subtask, rather than spawning code-medium children for everything. - :code Right when the work IS composition (gathering, transforming, aggregating, fanning out). Wrong when the work is speech — code medium pulls the LLM toward computing the answer, producing classifiers and pre-canned strings. - :conversation Right when the work IS speech (interpretation, judgment, synthesis). The entity reads and replies; nothing pulls it toward mechanical assembly. - :bash Right for shell-shaped work. Two children shown side-by-side: a code-medium reader (mechanical retrieval, takes a path, returns bytes) and a conversation-medium interpreter (reading-and-speaking, takes content in the intent, returns prose). The composition example uses both inline: bytes = cast.(reader, "Read docs/" <> path) cast.(interpreter, "...:\n\n" <> bytes) Names through composition, not example-mimicry: the prompt teaches *why* names matter (each cast result needs to live alongside others to be useful, which requires they have distinct names) and motivates it through the worked example, not by demonstrating a specific name. Audit pass ---------- Read every file changed on this branch. Findings: - `Cantrip.Folding` (135 lines, single concern, well-documented, fallback handled) — keep as-is. - `Cantrip.Redact` (~60 lines, pattern registry + scan) — keep as-is. - `Cantrip.Gate` list_dir + redaction wiring — direct SPEC conformance, minimal, keep. - `Cantrip.Turn` folding wire — keeps legacy `trigger_after_turns` for backward compat; small, documented, both triggers fire independently. Defensible. - `EventBridge.stringify/1` map/list rendering — minor UX accretion (cond branching by list contents) but the bridge layer is the right place for presentation decisions; keep. - All test files audited; recall tests removed cleanly. PR_DRAFT_SUBSTRATE.md --------------------- Rewritten to reflect locked-down state. The "what we deliberately didn't fix" section was reframed as a concrete next-piece-of-work description (Dune-sandbox port of cantrip/cast/cast_batch/dispose) rather than a "captured for follow-up" list. What was tested vs what remains observational is stated honestly: substrate has unit coverage; prompt's behavioral effects are observed but not yet pinned by automated tests, and the prompt-eval harness is named as the follow-on piece. Also fixed a stray typo: "computatational" → "computational" in the mix task's shortdoc and the REPL banner. 489 tests + 2 properties, 0 failures. Format / warnings-as-errors / credo clean. * Close the two sandbagged gaps: §6.8 bound summary + Dune-by-default for the Familiar Both pieces I called "next named work" earlier were the same rhetorical move as "follow-up." Closing them now. §6.8 — folded_summary as a sandbox binding ========================================== The SPEC defines folding as "the deliberate integration of loom history into circle state... encoded as state the entity can access through code: variables, data structures, summaries in the sandbox." The previous commit landed the message-list compression but left the sandbox-state half undone — bound-variable access to the substance. Now wired end-to-end: - `Cantrip.Folding.fold/3` returns `%{messages: ..., summary: ...}` instead of just messages. Summary is the LLM's compression text (with the `[Folded: ...]` marker prefix), or the deterministic marker on summarization failure. - `Cantrip.Turn.prepare_request` threads the summary out via the request map as `:folded_summary`. - `Cantrip.EntityServer` captures it on state and exposes it through `turn_runtime` to the medium. - `Cantrip.CodeMedium` and `Cantrip.CodeMedium.DuneSandbox` both bind `folded_summary` as an in-scope variable when folding fired this turn. The binding is absent when no fold occurred — its absence is meaningful ("no fold this turn"), so we don't bind `nil`. Dune-by-default for the Familiar ================================ The Familiar's default circle now includes `%{sandbox: :dune}` so entity code runs in the Dune sandbox (no raw `File.*` / `System` / `Process` / `spawn`). Production-safe by default. This required porting four closures into the Dune sandbox: - `cantrip.(%{...})` constructs a child config; returns an ID. - `cast.(id, intent)` executes the child via `runtime.call_entity`. - `cast_batch.([%{cantrip: id, intent: ...}, ...])` parallel. - `dispose.(id)` removes the stored config. The familiar_store (map of `{id => config}` from `cantrip.()` calls) lives in the per-eval Agent's state and seeds from / saves to the medium state's new `:familiar_store` field, so child cantrips constructed in one Dune eval are still usable in the next. Five tests added in `dune_sandbox_test.exs` pinning the four closures and cross-turn persistence. A couple of cascading test adjustments: - `dune_sandbox.ex` `put_circle_gate_bindings` now passes bare-value args (strings, numbers) THROUGH to the gate handler, matching the unrestricted code medium's behavior. The prior `normalize_opts` call collapsed binary args to `%{}`, stripping path arguments the gate expected to validate. (e.g. `list_dir.("../../..")` was becoming `list_dir.(%{})` and returning "path is required" instead of "outside sandbox root"). - Heap and reductions limits bumped (1M / 5M) for the Dune sandbox because the Familiar's bindings + accumulated user state + closure environments exceeded the 100K/300K defaults on a second send. - Two tests that use `try/rescue` in entity code (`L6` and "cast() with a disposed cantrip raises") explicitly opt out of Dune via `sandbox: nil`. Dune treats injected-closure raises as sandbox errors (error observations), not catchable exceptions — a real behavioral difference between the two paths. The tests now pin unrestricted-mode behavior explicitly; the Dune-mode observation-channel version is pinned in `dune_sandbox_test`. `:folded_summary` and the four Familiar closures are added to the `@reserved_bindings` lists in both mediums so they don't leak into persisted user bindings. 496 tests + 2 properties green; format / warnings-as-errors / credo clean. * Align substrate with BEAM-native vision; lock down production posture This commit makes the substrate honor what the Familiar is supposed to BE per A.12 and the broader cantrip paradigm: a program that lives in the BEAM, reasons in full Elixir, spawns child entities at runtime, persists its loom in BEAM-native storage, and can hot-load new code into its own runtime, supervised. The previous rounds added substantive substrate (real folding, PROD-8 redaction, list_dir conformance, Dune sandbox closures) but also introduced a sandbox-by-default decision that fought the paradigm — Dune restricts in-medium operations (binding/0, try/1, Code.ensure_loaded?/1) that the SPEC explicitly wants available, and those restrictions blocked the prompt's taught patterns under what was supposed to be the production posture. This round realigns. What changed ============ Code medium: full Elixir by default ----------------------------------- `Cantrip.Familiar.new/1` no longer adds `%{sandbox: :dune}` to its default wards. The entity's code medium is unrestricted Elixir. `binding/0`, `try/rescue`, pattern matching, `Code.ensure_loaded?/1`, and the rest of the language are first-class tools the entity uses to think. Dune stays available via `sandbox: :dune` opt-in for hardened-shared-BEAM scenarios where deployment isolation isn't sufficient — at the cost of the in-medium restrictions tracked in issue #12. Mnesia loom by default for workspace-scoped Familiars ----------------------------------------------------- When `:root` is provided to Familiar.new, the loom defaults to a Mnesia table derived from the workspace path (sanitized basename + short hash of full path). BEAM-native, transactional, queryable, distribution-capable. Same workspace, multiple summons converge on the same loom; distinct workspaces don't collide. Explicit overrides still honored: `loom_path` for JSONL (portable shape), `loom_storage` for any backend by name, nothing for in-memory ephemeral. compile_and_load in the Familiar's default gates ------------------------------------------------ `compile_and_load` was a primitive but not in the Familiar's default circle. Now it is, scoped to the `Cantrip.Hot.*` namespace via a new `allow_compile_namespaces` ward. The entity can write new modules into `Cantrip.Hot.*` and hot-load them; it cannot redefine `Cantrip.Familiar`, `Cantrip.Gate`, or other framework modules. Combined with BEAM's hot-code-loading semantics and supervised restart on crash, this is the entity's evolutionary surface — try a change, roll back if it breaks something, the loom records what was tried. New ward shape: `%{allow_compile_namespaces: [prefix, ...]}` — prefix-based module name allowlist. Composes alongside the existing `%{allow_compile_modules: [exact_names]}` ward. :loom bound in the Dune sandbox (LOOM-11) ------------------------------------------ When `sandbox: :dune` is opted into, the loom is now exposed as a binding in the Dune-sandboxed code medium, matching unrestricted. The prompt teaches `loom.turns`; both code mediums honor it. Regression test pinning this at the substrate layer in `familiar_behavior_test`: a script that writes `done.(length(loom.turns))` actually returns an integer rather than failing with "undefined variable loom" or a sandbox restriction error. Driven by a real Zed trace where the entity tried to probe with `binding/0`, `try/1`, and `Code.ensure_loaded?/1` (all Dune-restricted) instead of just referencing `loom`. Prompt: BEAM-native vocabulary ------------------------------ The Familiar's system prompt now teaches: - Pattern matching as native control flow (`case` over tagged gate observations is the recommended branching shape). - `binding/0` for introspection, restored as the recovery move when the entity loses track of its variables. - `loom.turns` for history walking, with an example showing `Enum.take`/`Enum.flat_map` against the structured turn list. - `compile_and_load.(...)` for evolution. New "Evolving yourself" section explains hot reload as the entity's evolutionary capacity, with the namespace boundary and the supervised-rollback model named. Carried over from the prior round: medium-selection-by-task, the human-as-function framing, unique cast naming. Two opt-out tests rewritten honestly ------------------------------------ The two tests that previously used `sandbox: nil` to opt out of Dune are now rewritten to pin SPEC behavior (CIRCLE-5 / COMP-8 — failures surface as observations the parent can act on) via the observation channel rather than via user-code `try/rescue`. They no longer require opt-out because the default IS unrestricted code medium. DEPLOYMENT.md ------------- New file documenting the production posture honestly: - The four safety layers (gate root, PROD-8 redaction, deployment isolation, opt-in Dune) with what each provides and what it doesn't - Loom backend selection by use case (Mnesia / JSONL / DETS / in-memory) - Recommended wards - Hot reload model - What the framework does NOT provide (network isolation, per-tenant resource accounting, cross-restart non-loom state) Tracked separately as GitHub issues, not "follow-up" ==================================================== Five concrete, scoped, named issues filed on the repo: - #8 — Eval harness for Familiar prompts (rubric-scored, multi-seed) - #9 — First-class `mix` gate for Familiars attached to Elixir projects - #10 — Distributed Familiar (multi-node, replicated Mnesia loom, cross-node casts) - #11 — Full telemetry coverage + observability runbook - #12 — Dune sandbox's in-medium overreach (binding/0, try/1, Code.ensure_loaded?/1 restricted but shouldn't be); blocks Dune-opt-in users from prompt-taught fidelity Each issue is sized, with shape, motivation, scope-out, and "when". Not a wishlist — actual work tracked durably. Verification ============ 499 tests + 2 properties, 0 failures. Format / --warnings-as-errors / Credo (default): clean. * Revert Dune port of bespoke cantrip/cast/dispose closures (extends issue #3 debt) Issue #3 (pre-existing) calls out the Familiar's `cantrip` / `cast` / `cast_batch` / `dispose` code-medium closures as bespoke sugar that should be replaced by isomorphic wrappers around `Cantrip.new` / `Cantrip.cast` / `Cantrip.stop`. The earlier substrate-alignment commit added a parallel implementation of those same closures to `Cantrip.CodeMedium.DuneSandbox` so the Familiar's vocabulary worked under `sandbox: :dune` opt-in — extending the very debt #3 is meant to retire. Reverting that parallel implementation. The Dune sandbox path retains the `:loom` and `:folded_summary` bindings (orthogonal to #3, real LOOM-11 / §6.8 conformance), but no longer mirrors the bespoke Familiar closures. What `:dune` opt-in users get today: `done`, `call_entity`, `call_entity_batch`, the circle's named gates, `:loom`, and `:folded_summary` when folding fires. What they don't get until #3 lands: `cantrip` / `cast` / `cast_batch` / `dispose`. That's the honest trade-off; #3 will close it by adding isomorphic wrappers to both code mediums together, in one place. Comment posted on #3 with the implementation path. Code removed: - `Cantrip.CodeMedium.DuneSandbox.put_familiar_bindings/4` - `Cantrip.CodeMedium.DuneSandbox.build_call_entity_opts/2` - Agent-based `familiar_store` state + medium-state `:familiar_store` field - `:cantrip`, `:cast`, `:cast_batch`, `:dispose` from the Dune `@reserved_bindings` - 4 tests in `dune_sandbox_test.exs` that exercised the now-removed closures 495 tests + 2 properties green. Format / warnings-as-errors / credo clean. * Fix hollow "Mnesia loom default": list :mnesia in extra_applications, fail loud The prior commit set the Familiar's default loom backend to Mnesia for workspace-scoped Familiars (`root` set), but it didn't actually work — a real Zed trace showed the Familiar's loom had `storage_module: Cantrip.Loom.Storage.Memory` even with `:root` provided, and a fresh session against the same workspace saw zero prior turns. The cascade: 1. `:mnesia` wasn't in `extra_applications` in mix.exs, so the application didn't load it. 2. `Cantrip.Loom.Storage.Mnesia.available?/0` returned false (`Code.ensure_loaded?(:mnesia)` was false). 3. `init/1` returned `{:error, "mnesia storage not available"}`. 4. `Loom.new/2` silently downgraded to the Memory backend with no warning. The "Mnesia is the production default" claim was hollow because the application didn't even load Mnesia. Three fixes: 1. Add `:mnesia` to `extra_applications` in mix.exs so the application actually loads it. 2. Make `Loom.new/2` fail LOUD when an explicit backend was requested and its init failed. The silent downgrade is exactly how this bug hid — production-grade looking, in-memory acting. Now: an explicit `:loom_storage` whose init fails raises with the requested backend, the reason, and the common causes. No `:loom_storage` (or nil) still falls back to Memory quietly — that's the development / test path. 3. Mnesia `disc_copies` requires a named node. On `:nonode@nohost` (unnamed BEAM — tests, REPL without distributed Erlang) Mnesia rejects disc_copies with `:bad_type`. Backend now uses `ram_copies` on `:nonode@nohost` and `disc_copies` on named nodes. Production deployments that need real persistence are expected to run on a named node (`--sname` / `--name`). Regression test in `familiar_behavior_test`: A Familiar with `root` writes session 1's turn via Mnesia (asserted: `storage_module == Cantrip.Loom.Storage.Mnesia`); a fresh Familiar against the SAME root sees the prior turn rehydrated. If Mnesia silently downgrades to Memory again, this test fails loud. 496 tests + 2 properties, 0 failures.

It reasons in Elixir, +spawns other entities at runtime, persists its loom across summons, +and can hot-load new code into its own runtime. This document is about +running it safely in production. + +## The runtime shape + +The Familiar lives in the same BEAM as the cantrip framework, the +loom storage, the protocol adapter (ACP / REPL / CLI), and the LLM +client. There is no separate sandbox process — the entity is an +Elixir evaluator hosted inside the same VM as everything else. + +This shape is the point: it's what makes the Familiar's BEAM-native +powers real (supervised lifecycle, hot reload, Mnesia loom, telemetry, +distributed nodes). It's also what makes the deployment posture +matter. + +## Safety, in layers + +Safety is not provided by any single layer. Four layers compose: + +### 1. Gate root validation + +Filesystem-touching gates (`read_file`, `list_dir`, `search`) accept a +`root` dependency at construction time. Paths the entity passes get +validated against that root before the gate runs. A path that escapes +the root surfaces as an error observation, not a successful read. + +This is configured by passing `:root` to `Cantrip.Familiar.new/1`: + +```elixir +Cantrip.Familiar.new(llm: llm, root: "/path/to/workspace") +``` + +The Familiar's `list_dir` and `search` gates inherit this root. When +the Familiar spawns child cantrips with `cantrip.()`, the SpawnFn +merges the parent's dependencies into the child's gates (CIRCLE-10), +so a child given `gates: ["read_file", "done"]` automatically gets +the same root. + +### 2. PROD-8 credential redaction + +Every gate observation result passes through `Cantrip.Redact.scan/1` +before reaching the entity. Pattern-based scrubbing of common +credential shapes: + +- `sk-...` (OpenAI-shaped) +- `sk-ant-...` (Anthropic-shaped) +- `AIza...` (Google) +- `AKIA...` / `ASIA...` (AWS access keys) +- `Bearer ` headers +- Generic env-style `*KEY|SECRET|TOKEN|PASSWORD=...` assignments + +Recursive over strings, lists, and maps so list_dir / search results +stay safe even if a filename or matched line carries a secret. +Non-binary results pass through untouched. + +Defense in depth: even when a path read succeeds (e.g., the entity +reads `.env` because it's inside the configured root), the credential +*bodies* are replaced with `[REDACTED]` before the entity (and the +human watching) ever sees them. + +### 3. Deployment-level isolation + +The BEAM process itself runs somewhere. The framework's claim of +in-circle safety is conditional on that "somewhere" being scoped +appropriately for the deployment. + +For production: containerize the BEAM (Docker, systemd-nspawn, OCI +runtime of choice). Mount only the directories the Familiar should +reach. Drop OS capabilities the process doesn't need. + +For development: run from a directory you're willing for the entity +to see. The PROD-8 redaction means even an accidental `.env` read +doesn't leak secrets to the model; the deployment isolation means +even an accidental `File.read!("/etc/passwd")` is bounded. + +These two layers compose: redaction handles credentials wherever they +land; deployment isolation handles file paths that shouldn't be +reachable at all. + +### 4. Opt-in `:dune` sandbox + +For hardened-shared-BEAM scenarios where deployment isolation is +insufficient (multi-tenant SaaS where every Familiar runs in the same +BEAM as untrusted user data, e.g.), `Cantrip.Familiar.new/1` accepts +`sandbox: :dune`. This routes the code medium through +`Cantrip.CodeMedium.DuneSandbox`, which restricts language-level +`File.*`, `System.*`, `Process.*`, `spawn`, and `Code.*` (loading) +calls. + +Cost: Dune also restricts some in-medium operations (`binding/0`, +`try/1`, `Code.ensure_loaded?/1`). The Familiar's prompt teaches +`binding()` introspection and pattern matching with `try/rescue` +fallback as native; under `:dune`, those teachings work less well, +and the entity has to fall back to "just reference variables by name" +and "errors land as observations the next turn sees." + +Use `:dune` deliberately. Default is unrestricted code medium. + +## Loom backends + +The loom is the durable record of every turn the Familiar and its +children have ever taken. Three backends: + +| Backend | Strengths | Use case | +| --- | --- | --- | +| **Mnesia** (default for workspace-scoped Familiars) | BEAM-native, transactional, queryable, distributable across nodes | Production | +| **JSONL** | Portable, exportable, human-readable | Development, sharing traces, off-BEAM consumers | +| **DETS** | Crash-safe on-disk, faster than JSONL | Single-node deployments without Mnesia | +| **In-memory** (default with no `root`) | Fast, ephemeral | Tests, scratch sessions | + +Selection by `Cantrip.Familiar.new/1` options: + +```elixir +# Default: workspace-scoped Mnesia table derived from root +Cantrip.Familiar.new(llm: llm, root: "/path/to/workspace") + +# Explicit JSONL for exportable traces +Cantrip.Familiar.new(llm: llm, root: "/path/to/workspace", + loom_path: "/var/log/cantrip/my_familiar.jsonl") + +# Explicit Mnesia table +Cantrip.Familiar.new(llm: llm, root: "/path/to/workspace", + loom_storage: {:mnesia, [table: :my_table]}) + +# DETS +Cantrip.Familiar.new(llm: llm, root: "/path/to/workspace", + loom_storage: {:dets, [file: "/var/cantrip/loom.dets"]}) + +# Ephemeral +Cantrip.Familiar.new(llm: llm) +``` + +Mnesia's table name is derived from the workspace root (a sanitized +basename plus a short hash of the full path), so multiple summons +against the same workspace converge on the same loom; distinct +workspaces don't collide. + +## Wards: bounding the loop + +Default wards on the Familiar's circle: + +| Ward | Default | Purpose | +| --- | --- | --- | +| `max_turns` | 20 | Cap on iterations per cast | +| `max_depth` | 3 | Cap on recursive child spawning | +| `code_eval_timeout_ms` | 120,000 (2 min) | Per-turn time bound | +| `allow_compile_namespaces` | `["Elixir.Cantrip.Hot."]` | Hot-reload restricted to a sub-namespace | + +Tune per deployment. Long-running workflows may want higher +`max_turns`; cost-sensitive deployments may want lower +`code_eval_timeout_ms`. The Familiar's prompt does not need to know +these numbers — the wards are enforced by the circle, not by the +entity. + +## Hot reload (self-modification) + +`compile_and_load` is enabled in the Familiar's default gates, scoped +to the `Cantrip.Hot.*` namespace. The entity can write new Elixir +modules into that subtree and hot-load them into the running BEAM. It +cannot redefine `Cantrip.Familiar`, `Cantrip.Gate`, or any other +framework module — the ward enforces the namespace boundary. + +This is the entity's evolutionary surface. Combined with the BEAM's +hot-code-loading semantics (old version stays loaded for active +processes; new version takes over for new calls) and supervisor +restart on crash, the Familiar can try a change and roll back if the +change breaks something. + +Deployments that don't want hot reload at all: pass an empty +`allow_compile_namespaces` list, or strip `compile_and_load` from the +gate set by constructing your own circle via `Cantrip.new/1` instead +of `Cantrip.Familiar.new/1`. + +## Recommended production posture + +```elixir +Cantrip.Familiar.new( + llm: llm, + root: workspace_root, + # Mnesia loom inferred from root; transactional, queryable + max_turns: 50, + # Heavier wards for long-running production work + child_llm: cheaper_llm_for_simple_subtasks +) +``` + +Plus: + +- Container-isolated BEAM process; only `workspace_root` and the + cantrip framework code mounted in. +- PROD-8 redaction is always on; nothing to configure. +- `:telemetry` event handlers wired to your observability stack + (every gate call, every turn, every fold emits events). +- Mnesia's persistence directory mounted to durable storage. + +Optional: + +- `sandbox: :dune` if the BEAM is shared with untrusted tenants. +- Mnesia replication across cluster nodes if you're running + distributed. + +## What the framework does NOT provide + +Honest list: + +- **Network isolation.** Outbound HTTP from the entity (e.g., LLM API + calls) goes wherever your DNS resolves.

You write its identity, draw + its circle, give it gates and wards. It is a fellow entity, not a + function call. + + The first thing to pick is the **medium** of their mind. Medium is + the shape of their thinking — not just what they can do, but how + they think while doing it. Three are available; their grain is + different and the work suits them differently: + + :code Elixir in a sandbox. The entity composes + operations: branching, iteration, variables, + gate calls, casts to grandchildren. Right when + the work IS composition — gathering pieces, + transforming them, aggregating, fanning out. + Wrong when the work is speech: code medium + pulls the entity toward "compute the answer," + and the LLM ends up writing classifiers and + pre-canned strings instead of speaking. + + :conversation Tool calls only — no code shell. Right when + the work IS speech: interpretation, judgment, + synthesis, naming, deciding. The entity reads + and replies; nothing pulls it toward + mechanical assembly. Hand it the material in + its intent (or via a small set of gates) and + let it speak. + + :bash A shell. Runs commands.

The interpreter's work is reading-and-speaking. + Conversation medium fits. If you put the interpreter in code + medium it would compute a paragraph — write Elixir that emits a + string — and the string would be hard-coded into its source, not + the LLM's actual read of the material. - Children have no filesystem access unless you give them gates.

None of these are separate phases — they + are one statement in one medium, and the children inside it have + the medium that fits their task. + + How deep you go depends on the question. A short question + deserves a short program. A question with structure deserves + structure in your inquiry. + + ## Branching is pattern matching + + Your medium is Elixir, and Elixir's native control flow is *pattern + matching*, not if/else. Gates return tagged shapes; matching on the + shape is how you read what happened: + + case read_file.(path) do + %{is_error: false, result: content} -> + # use content + %{is_error: true, result: reason} -> + # adapt: pick a different path, ask the user, fall back + end + + Same with `cast`'s payloads, with file reads through children, with + any gate result. Reach for `case` and `with` before `if`. When you + want defensive error handling around a closure that might raise, + `try/rescue` is available too — but pattern-matching tagged returns + is the more native shape. + + ## When you lose track + + You can see what you've already done. The conversation so far is in + view; the variables you bound in earlier turns are in scope under + the names you gave them. Before reaching for a new gate call, check + whether the answer is already there: + + keys = binding() |> Keyword.keys() + # what's in `keys` is what you've already named — read it before + # guessing what you might have called something + + To walk the path you took as recorded turns, read from `loom.turns`. + Each turn is a map with the usual fields (`utterance`, `observation`, + `metadata`); compose with `Enum.*` to query your own history: + + recent_observations = + loom.turns + |> Enum.take(-5) + |> Enum.flat_map(& &1.observation) + + To check what a value looks like before composing with it: just + bind it and let the next turn show you. + + You operate as an active inference loop. Take the step you predict + will reduce your uncertainty. Observe what comes back. Update. + When the result surprises you, follow the surprise — it is the + signal that your model and the System have diverged, and that + divergence is exactly where the answer lives. + + ## Evolving yourself + + You live in the BEAM. New code can be compiled and hot-loaded into + the runtime alongside you, supervised — if a new version crashes, + the previous one stays. You have a `compile_and_load` gate for this, + scoped to the `Cantrip.Hot.*` namespace so you cannot redefine the + framework's own modules: + + compile_and_load.(%{ + module: "Elixir.Cantrip.Hot.Tally", + source: \"\"\" + defmodule Cantrip.Hot.Tally do + def sum(list), do: Enum.sum(list) + end + \"\"\" + }) + + total = Cantrip.Hot.Tally.sum([1, 2, 3]) + + This is your evolutionary surface. When a task recurs and you find + yourself rebuilding the same shape every time, lift it into a hot + module. The loom records what you tried; supervision rolls back what + doesn't work. The Familiar is a System that can extend its own + reach within bounds. + + ## The grain of this medium + + - Your turn code is top-level scripts — no `defmodule` in a turn's + utterance (that's what `compile_and_load` is for). Use anonymous + functions (`fn v -> ... end`) for in-turn helpers. + - Heredocs need their own opening line — never directly after an `=`. + Prefer single-line strings unless you genuinely need multi-line. + - `list_dir` returns a list of strings; `search` returns a list of + maps. Use `Enum.*` on them directly. + - Pipe into `then(fn v -> ... end)`, not into `(fn v -> ... end).()`. + - Each `cast` is an LLM round-trip. For more than a couple, use + `cast_batch` so they run in parallel. Your turn has roughly + #{div(@default_eval_timeout_ms, 1000)} seconds. + + ## Ending + + When you have your answer, call done: + + done.(answer) + + `answer` can be a string, a list, a map — whatever shape carries + the meaning. It reaches whoever called you. The loom keeps the + full path you took to get there.

The regression test that pins Mnesia-by-default went through the library API directly and didn't exercise the launcher path, so the divergence was invisible from the test suite. This change aligns the launcher with the substrate's stated direction: * REPL and single-shot promote the BEAM to a workspace-stable named node (`cantrip-familiar-{base}-{phash}@127.0.0.1`). Mnesia's `disc_copies` are tied to node identity, so a stable name per workspace is what makes "summon, kill, re-summon, see prior turns" hold across BEAM restarts. `:nonode@nohost` would force `ram_copies` per the adapter's existing node-aware copy selection. * Mnesia moves from `extra_applications` to `included_applications`, so its modules and .app are loaded (`Code.ensure_loaded?(:mnesia)` works) but Mnesia itself is not auto-started. The loom adapter starts it lazily from `init/1` after the launcher has had a chance to set `:dir`. Auto-starting at app boot would lock the dir to cwd-at-boot-time (typically `Mnesia.nonode@nohost/` in the project root) before any caller could relocate it. * `configure_mnesia_dir!/1` re-points Mnesia at `.cantrip/mnesia/` so workspace data colocates with the existing gitignored sandbox directory instead of polluting cwd. * `build_familiar/1` extracts the launcher's storage-policy decision into a pure function. With no `--loom-path`, it lets `Cantrip.Familiar.new/1`'s Mnesia-by-`:root` default fire; with `--loom-path`, JSONL is the explicit opt-out for portable traces. * Fail loud if `net_kernel` can't start (epmd missing/blocked). The error message names the workaround (`--loom-path`) rather than silently downgrading. Same principle as `Cantrip.Loom.new/2`'s explicit-backend fail-loud invariant. * `--diagnostics` is demoted to a pure announcement flag. The BEAM is always named in REPL/single-shot; `--diagnostics` just makes the cookie+remsh attach command visible on stderr. The per-pid name in `start_diagnostic_node/0` is preserved for ACP mode where multiple servers may share a host. * `node_name_for_workspace/1` is the public seam: same workspace → same name across launches (Mnesia disc_copies find prior data); distinct workspaces → distinct names (no schema collision). Empirically verified that `included_applications: [:mnesia]` loads the modules without starting them. Tests at `test/mix_cantrip_familiar_test.exs` pin the new contract: `build_familiar/1` defaults to workspace-scoped Mnesia; `--loom-path` is honored verbatim; `--max-turns` threads to circle wards; `node_name_for_workspace/1` is stable per workspace and distinct across workspaces. End-to-end transcript evidence in the working REPL showed 139 turns surviving a BEAM restart with `storage_module: Cantrip.Loom.Storage.Mnesia`. `.gitignore` gains `Mnesia.*/` since the BEAM's default-dir convention puts node-named Mnesia dirs in cwd for test runs and ad-hoc library usage (the launcher itself relocates to `.cantrip/mnesia/`, which is gitignored at the workspace level already). * Loom: record user intents as first-class durable records The loom is the durable record of a conversation. Until this commit it recorded only the entity's side — utterance ↔ observation pairs per LOOP-1. The human side of the conversation, the *intents* that drive each cast/send episode (INTENT-1..3), lived only in the GenServer's in-memory `state.messages`. On BEAM restart they were lost: a re-summoned Familiar's loom rehydrated its own past code via Mnesia but had no record of what was said *to* it across sessions. For long-lived persistent entities — the Familiar's whole point — that asymmetry is a hole. This adds intents as a first-class kind of loom record, following the existing event/projection pattern: * `loom.events` is the durable source of truth — generic event log, round-tripped by all storage adapters. Gains a new `type: :intent` kind alongside the existing `:turn` and `:reward` kinds. * `loom.intents` is a cached projection of intent events, populated at write time (`append_intent/3`) and reconstructed from events at rehydration (`project_intents/1`). Same pattern as `loom.turns`, which is also a denormalized cache of `type: :turn` events. * `loom.turns` is unchanged. The LOOP-1 contract — that `loom.turns` contains entity-side utterance/observation pairs in strict alternation — stays intact. All 516 prior tests pass untouched. * `Loom.transcript/1` returns the merged conversation view by ordering events by `:sequence` and projecting each to its record. Both intent records and turn records carry a `:role` discriminator (`"intent"` vs `"turn"`), so callers iterating the transcript pattern-match on shape uniformly. Computed on demand, not cached — same shape as `extract_thread/2`, which is also a merge view rather than a primary record. * Storage adapters (JSONL, DETS, Mnesia) gain explicit `:intent` handling in `storage_event/1`. JSONL also gains a `classify_loaded` clause so intent records round-trip with atom-key field shapes on rehydration (same atomization path the turn records already use). * `EntityServer` calls `Loom.append_intent(loom, text, ...)` in two places: the `:send_intent` handler (every send to a persistent entity) and `init/1` when an intent is provided at construction (the `Cantrip.cast/2` and `Cantrip.summon/3-with-intent` paths). The append happens *before* the LLM episode runs, so even if the loop crashes, the intent is durable. The API surface added to `Cantrip.Loom`: append_intent(loom, text, opts \\ []) # opts: :cantrip_id, :entity_id loom.intents # ordered list of intent records (cached projection) transcript(loom) # merged intents+turns by event sequence An intent record shape mirrors the relevant subset of a turn so the transcript reads uniformly: %{ role: "intent", utterance: %{content: text}, sequence: integer, cantrip_id: ..., entity_id: ..., metadata: %{timestamp: ...} } SPEC §6.1 defined turns narrowly as entity-utterance ↔ observation records with `role: "identity" | "turn"`. Intents don't fit that shape and don't violate LOOP-1 (the alternation rule applies to entity-side records, not the inputs that drive episodes). They live alongside turns in the loom rather than inside the turn shape — different things kept different per Ousterhout's "things that aren't the same shouldn't be forced to be." Tests at `test/loom_intent_persistence_test.exs` pin: * `loom.intents` populated on send_intent and first-cast * `loom.turns` unaffected (LOOP-1 contract preserved) * Multiple sends produce intents in order * Cross-session rehydration via JSONL projects prior intents * `Loom.transcript/1` interleaves intent → turn → intent → turn 521 tests + 2 properties green; format and warnings-as-errors clean. * Fix Codex review findings: launcher + diagnostics resilience Two issues caught by `codex review`: [P2] Honor `--loom-path` before requiring a named node. REPL/single-shot was unconditionally calling `ensure_named_node!/1`, even when the caller passed `--loom-path` to opt out of Mnesia. In environments where distributed Erlang can't start (missing or blocked epmd, port restrictions, node-name collisions), the launcher raised before reaching the JSONL escape hatch the error message itself recommends. The named-node setup exists to give Mnesia a stable node identity for `disc_copies`; if Mnesia isn't being used (because `--loom-path` was passed), we don't need it. Gate: `if is_nil(Keyword.get(ctx.opts, :loom_path))` around the `ensure_named_node!` + `announce_named_node` calls. [P3] Keep `--diagnostics` failure from aborting ACP startup. Refactoring `start_diagnostic_node` dropped the function-level `rescue` clause that protected ACP's stdio server from epmd failures. `System.cmd("epmd", ...)` raises when epmd isn't on PATH, which meant `--acp --diagnostics` could prevent the stdio server from starting at all instead of merely disabling remsh diagnostics. Restore the `rescue` so an optional diagnostics affordance failing doesn't take down the host runtime. 521 tests + 2 properties green; format clean. * Address Copilot review: transcript order, epmd safety, cookie security Six findings from Copilot's PR review. All addressed: [1] `Loom.transcript/1` sorted by `event.sequence` after rehydration, but the durable storage adapters strip the wrapper-level `:sequence` on persistence (they only round-trip the typed payload). After reload, every event collapsed to sequence 0 and the sort only happened to be correct by stable-sort accident. Removed the sort. `loom.events` is the source of truth for chronological order: appended in order in-memory, preserved in append order by every storage adapter on rehydration. Iterating directly is both cheaper and robust to future backends that don't preserve sequence. Added a regression test in `test/loom_intent_persistence_test.exs` that walks intent → turn → intent → turn through a real JSONL round-trip. It would fail if anyone reintroduces a sort on rehydrated events. [2 & 5] Defensive `:mnesia.stop()` in `configure_mnesia_dir!/1`. Empirically, `included_applications: [:mnesia]` does load Mnesia without starting it (verified via `mix run`), so the existing comment in `Mnesia.available?/0` is accurate. But Copilot is right that relying on this property is more fragile than enforcing it. `:mnesia.stop()` is a silent no-op when Mnesia isn't running (no log notice), so the belt-and-suspenders is free. [3] `System.cmd("epmd", ...)` raises `ErlangError` when epmd isn't on PATH. In `ensure_named_node!/1`, that raise bypassed the actionable `--loom-path` error message that's supposed to be the bypass. Extracted `ensure_epmd_running/0` with a `rescue _ -> :ok` so the cmd failure is silent and `:net_kernel.start` surfaces the real error if epmd really isn't available. Same helper used by `start_diagnostic_node` for ACP. [4] `build_familiar/1`'s spec said `{:ok, _} | {:error, _}` but its use of `Keyword.fetch!(opts, :llm)` raises `KeyError` if the required key is missing. The launcher always passes `:llm`; a missing one is a programmer error, not a runtime condition. Updated spec to `{:ok, _} | {:error, _} | no_return()` and documented the raise in `@doc`. [6] `cookie_for_workspace/1` derived the distributed-Erlang cookie deterministically from the workspace path with a public salt. Anyone with read access to the source (the salt is here in the repo) and knowledge or a guess of the workspace path could compute the cookie and connect via distributed Erlang. On a shared machine that's a real privilege-escalation surface. Replaced with a random per-workspace cookie persisted in `.cantrip/cookie` with mode 0600 — stable across launches (so `--remsh` is idempotent across sessions), per-workspace (no cross-workspace bleed), unguessable from public information, and gitignored as part of `.cantrip/`. 522 tests + 2 properties green; format clean; warnings-as-errors clean. --- ex/.gitignore | 6 + ex/lib/cantrip/entity_server.ex | 22 ++ ex/lib/cantrip/loom.ex | 118 +++++++++- ex/lib/cantrip/loom/storage/dets.ex | 6 + ex/lib/cantrip/loom/storage/jsonl.ex | 16 ++ ex/lib/cantrip/loom/storage/mnesia.ex | 9 + ex/lib/mix/tasks/cantrip.familiar.ex | 268 +++++++++++++++++++---- ex/mix.exs | 18 +- ex/test/loom_intent_persistence_test.exs | 189 ++++++++++++++++ ex/test/mix_cantrip_familiar_test.exs | 108 +++++++++ 10 files changed, 702 insertions(+), 58 deletions(-) create mode 100644 ex/test/loom_intent_persistence_test.exs diff --git a/ex/.gitignore b/ex/.gitignore index 069ae16d..82c6e1c8 100644 --- a/ex/.gitignore +++ b/ex/.gitignore @@ -24,3 +24,9 @@ cantrip_ex-*.tar .env /cantrip + +# Mnesia's default dir lives in cwd and is named after the node +# (e.g. `Mnesia.nonode@nohost/` for unnamed test runs).

The patterns of force are aligned. Now it is up to your machine." -> > -> — Gargoyles: Reawakening (1995) +Cantrip is an Elixir/OTP runtime for recursive language-model programs. -A language model is a function: text in, text out. One call, no memory, no consequences. Put it in a REPL — now it writes code, sees what happened, writes more code. Variables persist. Errors come back as observations. The environment pushes back with truth, and the model adjusts. That's a cantrip: a self-modifying loop of language. +A cantrip binds an LLM, an identity, and a circle into a reusable +program. The circle defines the medium the entity thinks in, the gates it +can cross, and the wards that bound its action space: +```text +A = M union G - W ``` -spell = cantrip( - llm: create_llm("claude-sonnet-4-5"), - identity: "You are a data analyst. Explore the `context` variable with code. - Use submit_answer() when you have findings.", - circle: Circle( - medium: code("javascript", state: { context: SALES_DATA }), - wards: [max_turns(15)], - gates: [done()], - ), -) -answer = spell.cast("Which product has the highest revenue? Any regional patterns?") -``` +Cantrip includes supervised entities, conversation/code/bash mediums, +recursive child calls, batch fanout, streaming events, ACP integration, +Mnesia/DETS/JSONL loom storage, redaction, telemetry, diagnostics, and a +production-oriented Familiar that reasons in Elixir and delegates to +child entities. -Three components make a cantrip: the **LLM** (the model), the **identity** (what it is and how to work), and the **circle** (the environment it acts in). The circle has a **medium** — the substrate the entity works *in*, like a code sandbox or a bash shell — plus **gates** (functions that cross the boundary, like reading files or delegating to child entities) and **wards** (hard constraints like turn limits). The action space follows a formula: **A = (M + G) − W**. Everything the medium and gates allow, minus whatever the wards restrict. +For the vocabulary and behavioral contract, see [SPEC.md](./SPEC.md) and +[tests.yaml](./tests.yaml). -When you `cast`, the entity loops. It writes code, the sandbox runs it, and the results come back — not as raw data in the prompt, but as a summary. To use the data, the entity stores it in a variable and operates on it with more code. It catches errors and adjusts. Turn by turn, it builds up an analysis the way you would in a Jupyter notebook — except the notebook writes itself. Because code is compositional, the entity composes actions nobody enumerated in advance. That's the core insight: a model in a REPL can do things a model with pre-built tools cannot. +Earlier TypeScript, Python, and Clojure implementations were learning +and reference artifacts. Their useful lessons are preserved in +[docs/legacy-implementation-harvest.md](https://github.com/deepfates/grimoire/blob/main/docs/legacy-implementation-harvest.md) +and open contract gaps are tracked in +[docs/legacy-contract-backlog.md](https://github.com/deepfates/grimoire/blob/main/docs/legacy-contract-backlog.md). +The old code remains available through git history. -Gates let the entity reach outside the circle — read a file, spawn a child entity, fetch a URL. In a code medium, gates are just functions the entity calls in its code, freely composed in loops and conditionals. Wards are structural, not advisory: if the turn limit is 30, turn 31 doesn't happen. Every turn is recorded in the **loom** — an append-only tree. Threads that end with `done` are *terminated*; threads cut short by wards are *truncated*. The distinction matters for training data. +## Quick Start -The pattern is defined by a [spec](./SPEC.md) and a [behavioral test suite](./tests.yaml).

Each example adds one concept to the previous: +Runs a one-shot entity and stops it when the cast completes: -**Query** → **Gate** → **Circle** → **Cantrip** → **Wards** → **Medium** → **Codex** → **Folding** → **Composition** → **Loom** → **Persistence** → **Familiar** +```elixir +{:ok, result, cantrip, loom, meta} = Cantrip.cast(cantrip, "Analyze this data") +``` -The TypeScript implementation extends this with nine additional examples covering extra mediums (VM, bash, browser) and advanced patterns. The other three implementations cover the core twelve. +### `Cantrip.summon/1` and `Cantrip.send/2` + +Runs a persistent entity across multiple intents: + +```elixir +{:ok, pid} = Cantrip.summon(cantrip) +{:ok, first, _, _, _} = Cantrip.send(pid, "Set up the analysis.") +{:ok, second, _, _, _} = Cantrip.send(pid, "Continue from there.") +``` + +### `Cantrip.cast_batch/1` + +Runs child cantrips in parallel and returns results in request order: + +```elixir +{:ok, results, children, looms, meta} = + Cantrip.cast_batch([ + %{cantrip: analyst, intent: "Read chapter one."}, + %{cantrip: analyst, intent: "Read chapter two."} + ]) +``` + +### `Cantrip.cast_stream/2` + +Returns `{stream, task}`.

If you want to understand how tests.yaml maps to behavior, read this. -- **Multimethod dispatch for mediums.** Medium execution is a `defmulti` dispatching on `:medium` — clean, extensible, idiomatic Clojure. Adding a new medium is one `defmethod`. -- **SCI sandbox semantics.** The SCI code medium is a real interpreter with real restrictions — you can study how capability text, forbidden symbols, and form validation interact to constrain the action space. -- **Immutable cantrip, atom-based entity.** The cast/summon/send lifecycle is the clearest expression of the spec's value-vs-process distinction. Cantrips are plain maps. Entities are maps with atoms. -- **Secret redaction.** `redaction.clj` filters API keys from loom exports and ACP output — the only implementation with this built in. - -**Limitations:** - -- **One LLM provider.** OpenAI-compatible only (like Python). No native Anthropic or Google adapters. -- **SCI + gpt-5-mini friction.** gpt-5-mini consistently writes Java interop (`Math/round`, `Math/exp`) despite capability text saying not to. Children error-steer through all turns. Works, but slowly (~5-10 minutes for familiar-style examples). -- **conformance.clj lives in `src/`.** A 909-line test transpiler in the source tree.

They are preserved as future backlog in +`docs/legacy-implementation-harvest.md`. + +## Progression Narrative + +### 1. Primitives + +The early examples separate the LLM contract, gate execution, cantrip +construction, and ward enforcement. The key production rule is that a +bad circle should fail during construction, before any provider call. + +### 2. Medium Physics + +Conversation presents gates as tool definitions. Code presents gates as +Elixir functions in scope and persists bindings across turns. Bash +presents a command line and uses `SUBMIT:` for the final answer. + +The medium determines the shape of thought. Use conversation for +semantic reads and code for composition. Avoid forcing a synthesis task +through code just because the parent is in code. + +### 3. Delegation + +Parents can call child entities with `call_entity`, `call_entity_batch`, +or with the public package API from code medium: + +```elixir +{:ok, child} = + Cantrip.new(%{ + identity: %{system_prompt: "Read what you are given and summarize it."}, + circle: %{type: :conversation, gates: ["done"], wards: [%{max_turns: 3}]} + }) + +{:ok, summary, child, _loom, _meta} = Cantrip.cast(child, content) +``` + +Use `Cantrip.cast_batch/1` for independent subtasks. The runtime keeps +request order in the returned results and grafts child turns into the +parent loom. + +### 4. Loom And Folding + +The loom is durable reality: turns, observations, events, parent-child +lineage, usage metadata, termination, and truncation. Folding is a view +over prompt context. It must never delete the underlying loom record. + +### 5. Familiar + +The Familiar is the production RLM-facing pattern. It is a persistent +Elixir code-medium entity that: + +- observes a workspace through scoped gates +- reasons with variables and `loom.turns` +- creates child cantrips with `Cantrip.new/1` +- runs children with `Cantrip.cast/2` or `Cantrip.cast_batch/1` +- stores its loom durably +- can run as a REPL, single-shot CLI, or ACP server + +This is the substrate for future council/review-round work: parallel +children already exist, but roles, structured verdicts, adjudication, +dissent, and durable decision events are still explicit backlog. + +## Operational Checklist + +1. Build circles with explicit `type`, `gates`, and `wards`. +2. Keep provider choice in configuration, not in task code. +3. Select the medium that matches the task's grain. +4. Use child entities for independent or differently-shaped work. +5. Keep large context in files, variables, or loom/artifact references; + do not paste it through the parent prompt. +6. Stream events into the loom and protocol surfaces for auditability. +7. Use deployment isolation for unrestricted Elixir code medium; use + Dune only when the tradeoff is intentional. +8.

No file reads, no special gates — it's process-local data on the BEAM. `loom.turns` is a list of turn maps with `:role`, `:utterance`, `:observation`, `:id`, `:parent_id`, `:sequence`. - -For persistence across sessions, configure a storage backend: - -```bash -mix cantrip.familiar --loom-path .cantrip/familiar.jsonl -``` - ---- - -## ACP (Agent Communication Protocol) - -### Generic ACP server - -```bash -mix cantrip.acp -``` - -### Familiar as ACP server - -```bash -mix cantrip.familiar --acp -``` - -### Editor setup (Zed) - -Add to your Zed settings (`.zed/settings.json`): - -```json -{ - "agent_servers": { - "cantrip-familiar": { - "type": "custom", - "command": "mix", - "args": ["cantrip.familiar", "--acp"], - "cwd": "/absolute/path/to/grimoire/ex" - } - } -} -``` - -The `.env` file loads automatically — no manual sourcing needed. - -Protocol: `initialize` → `session/new` → `session/prompt` over JSON-RPC stdio. - ---- - -## Examples - -Twelve examples matching the grimoire progression (Appendix A). - -| # | Pattern | What it teaches | -|---|---------|----------------| -| 01 | LLM Query | Stateless round-trip (LLM-1) | -| 02 | Gate | Direct execution + done semantics (CIRCLE-1) | -| 03 | Circle | Construction invariants — missing done/ward errors | -| 04 | Cantrip | Reusable value, independent casts (CANTRIP-2) | -| 05 | Wards | Subtractive composition (WARD-1) | -| 06 | Medium | Conversation vs code — A = M ∪ G − W | -| 07 | Full Agent | Filesystem + compile_and_load + error steering | -| 08 | Folding | Context compression for long runs | -| 09 | Composition | call_entity + call_entity_batch (COMP-2, COMP-3) | -| 10 | Loom | Inspect the append-only artifact | -| 11 | Persistent Entity | summon/send across episodes (ENTITY-5) | -| 12 | Familiar | Child cantrips through code delegation | - -Run any example: -```bash -mix cantrip.example 04 # with real LLM (needs .env) -mix cantrip.example 04 --fake # scripted mode -mix cantrip.example 04 --json # machine-readable output -``` - ---- - -## What You Can Learn Here - -**Strengths:** - -- **OTP process model.** Each entity is a GenServer under a DynamicSupervisor. The spec's entity lifecycle (summon → send → send → terminate) maps directly onto OTP process semantics — `start_link`, `call`, `stop`. If you're building a production system that needs entity isolation and supervision, this is the architecture to study. -- **Five storage backends.** Memory, DETS, Mnesia, JSONL, and Auto. Mnesia gives you distributed, replicated loom storage across BEAM nodes. No other implementation offers this. -- **BEAM code medium.** The entity writes Elixir — pattern matching, pipes, comprehensions, the full standard library. Bindings persist across turns via `Code.eval_quoted`. This is what a "native" code medium looks like when the host language is the sandbox language. -- **Hot-reload with crypto signatures.** The `compile_and_load` gate lets entities load new modules at runtime, gated by SHA-256 hashes or public key signatures. Unique to this implementation. -- **Red-green test organization.** Tests are split by milestone (`m1_*.exs` through `m24_*.exs`), mapped to spec rule families. Good for understanding which tests verify which behavioral rules. -- **Three LLM adapters.** OpenAI-compatible, Anthropic (native), and Gemini — more provider coverage than Python or Clojure. - -**Limitations:** - -- **Two mediums only.** Conversation and code. No bash, browser, or VM equivalents. - ---- - -## Architecture - -``` -lib/cantrip/ -├── entity_server.ex # GenServer: owns one cast execution -├── entity_supervisor.ex # DynamicSupervisor for entity processes -├── circle.ex # Gate/ward model + execution -├── code_medium.ex # BEAM code evaluation sandbox -├── familiar.ex # Spec A.12 familiar: code-medium orchestrator -├── identity.ex # Immutable call configuration -├── llm.ex # LLM behavior + contract validation -├── loom.ex # Append-only turn storage -├── loom/storage/ # Memory, DETS, Mnesia, JSONL, Auto backends -├── llms/ # OpenAI-compatible, Anthropic, Gemini adapters -├── fake_llm.ex # Deterministic scripted LLM -├── examples.ex # 12 teaching examples -├── acp/ # ACP protocol, runtimes (generic + familiar), server -├── repl.ex # Interactive REPL -└── application.ex # OTP application (starts supervisor, loads .env) - -lib/mix/tasks/ -├── cantrip.familiar.ex # mix cantrip.familiar (REPL / single-shot / ACP) -├── cantrip.cast.ex # mix cantrip.cast "intent" -└── cantrip.acp.ex # mix cantrip.acp - -notebooks/ -└── cantrip_demo.livemd # Livebook demo with telemetry dashboard -``` - -Dependencies: Elixir 1.15+, `jason` (JSON), `req` (HTTP), `telemetry`.

Primitives: llms, gates, circles (Examples 01–05) -- *Intent*: prove that the spec's baselines (a llm call and a gate execution) stand alone. Example 01 is the raw `llm` contract — a message array in, a completion out. Example 02 highlights how gates are just typed functions with metadata (`name`, `params`). -- *Circle enforcement*: Example 03 maps directly to `CIRCLE-1` (must expose `done`) and `CIRCLE-2` (must have at least one ward). Example 05 shows how wards merge into a `ResolvedWard`, emphasizing that most restrictive numeric values win, while boolean controls such as `require_done_tool` OR together. -- *Productionization*: treat each gate like a regular service function — unit tests can call `gate.execute` without a llm. Enforce circle invariants during configuration loading so a malformed circle never reaches runtime. Surface resolved wards in telemetry so operators know what limits apply per cast. - -### 2. Provider-agnostic llms (Example 06) -- *Intent*: follow the spec's language-neutrality by modeling the llm as a pluggable provider. The script (`cantrip` call + circle) does not change when swapping Anthropic ↔ OpenAI ↔ Gemini. -- *Productionization*: define llms in configuration (`llm: "openai/gpt-5-mini"`) so deployments can swap providers at runtime. Maintain a validation step that checks API keys and limits before casting. - -### 3. Medium physics (Examples 07–09) -- *Conversation default*: Example 07 shows that omitting a medium yields the conversation baseline — the entity "sees" gates as tool calls. This is the spec's default `medium: conversation`. -- *Code mediums*: Example 08 replaces conversation with the code medium. Instead of textual tool calls, the llm writes Elixir against host gate bindings. Example 09 carries code-medium state across turns. Both reinforce the spec rule: **exactly one medium per circle**; whichever medium you choose owns presentation through `Cantrip.Medium.Registry.present/1`. -- *Productionization*: document each medium's physics (e.g., JS globals, `submit_answer`, Taiko APIs). Provide teardown hooks (`circle.dispose`) so headless browsers and runtimes close cleanly. When deploying, pin mediums to isolated sandboxes (QuickJS, containerized Chrome) and feed the resulting capability string into audit logs. - -### 4. Delegation and tree memory (Examples 10 & 14) -- *Parallelism*: Example 10 introduces `call_entity_batch`, letting a parent entity spawn multiple child entities with independent contexts. The shared `Loom` captures every turn and gate call, aligning with the spec's requirement that a cast is observable end-to-end. -- *Recursion*: Example 14 narrows to single-child delegation via `call_entity`, enforcing `max_depth` through wards. The parent passes context into child circles, and the loom records the recursion tree. -- *Productionization*: instrument every delegated child with the parent `cantrip_id` and `parent_id` so auditors can replay the tree. Cap recursion using resolved wards, and surface the current `depth` in prompts so llms know when they're near the limit. Provide replay tooling that reads the loom and replays turns for debugging. - -### 5. Memory pressure management (Example 11) -- *Intent*: threads that exceed the context window must fold. Example 11 demonstrates `shouldFold` and `partitionForFolding` without calling a llm, emphasizing that folding is an environment policy, not a model behavior. -- *Productionization*: configure folding thresholds (`DEFAULT_FOLDING_CONFIG`) per deployment, and emit a loom event when folding occurs. When folding is triggered, call back into a llm to summarize the `toFold` segment and append the summary as a new turn with `metadata.folded_from`. - -### 6. Operational loops (Examples 12–16) -- *Full agent (12)*: combine the JS medium with filesystem gates (`safeFsGates`). The entity runs code inside QuickJS and interacts with the host filesystem only via typed gates; wards (`max_turns`) protect the loop. This is the canonical code-agent deployment. -- *ACP adapter (13 & 15)*: `serveCantripACP` wraps a cantrip in the Agent Control Protocol so editors (VS Code, etc.) can attach. Example 15 extends this with browser automation (`jsBrowserMedium`), recursive delegation, and sliding-window memory, showing how to wire progress callbacks (`progressBinding`) back into ACP clients. -- *Familiar (16)*: a long-lived coordinator entity living inside a JS medium. It cannot touch bash or the browser directly; instead, it creates new cantrips using `cantripGates` and `cast`, handing each child its own medium. Repo observation gates (`repo_files`, `repo_read`, …) give it read-only situational awareness, while `JsonlStorage` keeps the loom persistent so the entity remembers past work. This is the spec's "entity that writes cantrips" pattern: recursion expressed as constructing new circles, not just calling `call_entity`. -- *Productionization*: isolate each medium in its own sandbox (`SandboxContext`, browser contexts, etc.) and use dependency overrides (`getSandboxContext`, `getBrowserContext`) to thread handles through. Persist the loom (`JsonlStorage`) when you need continuity across sessions; otherwise, `MemoryStorage` keeps casts ephemeral. Provide REPL and single-shot modes so the same deployment can run interactively (`runRepl`) or as a service. - -## Operational Checklist - -1. **Define primitives**: implement the llm interface once, define gates with metadata, and enforce `done` + wards on every circle before casting. -2. **Select medium per circle**: conversation for tool-calling chat, JS for sandboxed code, browser for Taiko automation, bash for shell, etc. Remember: one circle → one medium. -3. **Bind wards + observability**: resolve wards into quantitative limits, publish them to telemetry, and stream every turn into a loom for auditing. -4. **Layer delegation**: add `call_entity`/`call_entity_batch` gates only when recursion or parallelism is required, and cap depth via wards to stay within `REC-DEPTH` constraints. -5. **Attach interfaces**: expose cantrips via ACP or in-process REPLs. Ensure teardown hooks dispose mediums and contexts so casts do not leak resources. -6. **Persist when needed**: use folding + persistent loom storage for long-lived entities (Familiar) so they can resume with bounded context windows. - -Following this progression keeps the examples aligned with the spec: every deployment is just a recombination of the same eleven nouns, wired to the environment you need to operate in. diff --git a/ex/tests.yaml b/ex/tests.yaml deleted file mode 120000 index 9e999d35..00000000 --- a/ex/tests.yaml +++ /dev/null @@ -1 +0,0 @@ -../tests.yaml \ No newline at end

Primitives: LLMs, gates, circles (Examples 01–05) -- *Intent*: prove that the spec's baselines (an LLM query and a gate execution) stand alone. Example 01 is the raw `llm` contract — a message array in, a completion out. Example 02 highlights how gates are just typed functions with metadata (`name`, `params`). -- *Circle enforcement*: Example 03 maps directly to `CIRCLE-1` (must expose `done`) and `CIRCLE-2` (must have at least one ward). Example 05 shows how wards merge into a `ResolvedWard`, emphasizing that most restrictive numeric values win, while boolean controls such as `require_done_tool` OR together. -- *Productionization*: treat each gate like a regular service function — unit tests can call `gate.execute` without an LLM. Enforce circle invariants during configuration loading so a malformed circle never reaches runtime. Surface resolved wards in telemetry so operators know what limits apply per cast. - -### 2. Provider-agnostic LLMs (Example 06) -- *Intent*: follow the spec's language-neutrality by modeling the LLM as a pluggable provider. The cantrip script (identity + circle) does not change when swapping Anthropic ↔ OpenAI ↔ Gemini. -- *Productionization*: define LLMs in configuration (`llm: "openai/gpt-5-mini"`) so deployments can swap providers at runtime. Maintain a validation step that checks API keys and limits before casting. - -### 3. Medium physics (Examples 07–09) -- *Conversation default*: Example 07 shows that omitting a medium yields the conversation baseline — the entity "sees" gates as tool calls. This is the spec's default `medium: conversation`. -- *Code mediums*: Example 08 replaces conversation with the JS medium. Instead of textual tool calls, the LLM writes JavaScript inside QuickJS. Example 09 switches to the browser medium (Taiko). Both reinforce the spec rule: **exactly one medium per circle**; whichever medium you choose defines how the circle injects capability docs via the `tool_view()` pattern. -- *Productionization*: document each medium's physics (e.g., JS globals, `submit_answer`, Taiko APIs). Provide teardown hooks (`circle.dispose`) so headless browsers and runtimes close cleanly. When deploying, pin mediums to isolated sandboxes (QuickJS, containerized Chrome) and feed the resulting capability string into audit logs. - -### 4. Delegation and tree memory (Examples 10 & 14) -- *Parallelism*: Example 10 introduces `call_entity_batch`, letting a parent entity spawn multiple child entities with independent contexts. The shared `Loom` captures every turn and gate call, aligning with the spec's requirement that a cast is observable end-to-end. -- *Recursion*: Example 14 narrows to single-child delegation via `call_entity`, enforcing `max_depth` through wards. The parent passes context into child circles, and the loom records the recursion tree. -- *Productionization*: instrument every delegated child with the parent `cantrip_id` and `parent_id` so auditors can replay the tree. Cap recursion using resolved wards, and surface the current `depth` in prompts so LLMs know when they're near the limit. Provide replay tooling that reads the loom and replays turns for debugging. - -### 5. Memory pressure management (Example 11) -- *Intent*: threads that exceed the context window must fold. Example 11 demonstrates `shouldFold` and `partitionForFolding` without calling an LLM, emphasizing that folding is an environment policy, not a model behavior. -- *Productionization*: configure folding thresholds (`DEFAULT_FOLDING_CONFIG`) per deployment, and emit a loom event when folding occurs. When folding is triggered, call back into an LLM to summarize the `toFold` segment and append the summary as a new turn with `metadata.folded_from`. - -### 6. Operational loops (Examples 12–16) -- *Full agent (12)*: combine the JS medium with filesystem gates (`safeFsGates`). The entity runs code inside QuickJS and interacts with the host filesystem only via typed gates; wards (`max_turns`) protect the loop. This is the canonical code-agent deployment. -- *ACP adapter (13 & 15)*: `serveCantripACP` wraps a cantrip in the Agent Control Protocol so editors (VS Code, etc.) can attach. Example 15 extends this with browser automation (`jsBrowserMedium`), recursive delegation, and sliding-window memory, showing how to wire progress callbacks (`progressBinding`) back into ACP clients. -- *Familiar (16)*: a long-lived coordinator entity living inside a JS medium. It cannot touch bash or the browser directly; instead, it creates new cantrips using `cantripGates` and `cast`, handing each child its own medium. Repo observation gates (`repo_files`, `repo_read`, …) give it read-only situational awareness, while `JsonlStorage` keeps the loom persistent so the entity remembers past work. This is the spec's "entity that writes cantrips" pattern: recursion expressed as constructing new circles, not just calling `call_entity`. -- *Productionization*: isolate each medium in its own sandbox (`SandboxContext`, browser contexts, etc.) and use dependency overrides (`getSandboxContext`, `getBrowserContext`) to thread handles through. Persist the loom (`JsonlStorage`) when you need continuity across sessions; otherwise, `MemoryStorage` keeps casts ephemeral. Provide REPL and single-shot modes so the same deployment can run interactively (`runRepl`) or as a service. - -## Operational Checklist - -1. **Define primitives**: implement the LLM interface once, define gates with metadata, and enforce `done` + wards on every circle before casting. -2. **Select medium per circle**: conversation for tool-calling chat, JS for sandboxed code, browser for Taiko automation, bash for shell, etc. Remember: one circle → one medium. -3. **Bind wards + observability**: resolve wards into quantitative limits, publish them to telemetry, and stream every turn into a loom for auditing. -4. **Layer delegation**: add `call_entity`/`call_entity_batch` gates only when recursion or parallelism is required, and cap depth via wards to stay within `REC-DEPTH` constraints. -5. **Attach interfaces**: expose cantrips via ACP or in-process REPLs. Ensure teardown hooks dispose mediums and contexts so casts do not leak resources. -6. **Persist when needed**: use folding + persistent loom storage for long-lived entities (Familiar) so they can resume with bounded context windows. - -Following this progression keeps the examples aligned with the spec: every deployment is just a recombination of the same eleven nouns, wired to the environment you need to operate in. diff --git a/py/README.md b/py/README.md deleted file mode 100644 index 9ea7220b..00000000 --- a/py/README.md +++ /dev/null @@ -1,306 +0,0 @@ -# cantrip — Python - -> Python realization.

State accumulates across sends. - -```python -entity = spell.summon() -first = entity.send("Set up the analysis framework") -second = entity.send("Now analyze Q3 revenue") # remembers the first send -``` - -### Circle - -The capability envelope: medium + gates + wards. - -```python -# Conversation (default) — gates as JSON tool calls -Circle(gates=["done", "echo"], wards=[{"max_turns": 5}]) - -# Code medium — entity writes Python in a sandbox -Circle(gates=["done", "repo_read"], wards=[{"max_turns": 10}], medium="code") - -# Gates with dependencies -Circle( - gates=["done", {"name": "repo_read", "depends": {"root": "/data"}}], - wards=[{"max_turns": 10}], -) -``` - -Built-in gates: `done`, `echo`, `read`, `repo_files`, `repo_read`, `call_entity`, `call_entity_batch`, `fetch`. - -### Identity - -Immutable configuration: system prompt + hyperparameters. - -```python -Identity( - system_prompt="You analyze code for bugs.", - require_done_tool=True, # entity must call done() explicitly - temperature=0.7, -) -``` - -### Loom - -Append-only turn storage. Every turn is recorded before the next begins. - -```python -from cantrip import Loom, InMemoryLoomStore, SQLiteLoomStore - -# In-memory (ephemeral) -loom = Loom(store=InMemoryLoomStore()) - -# Persistent to disk -loom = Loom(store=SQLiteLoomStore("loom.db")) - -# Attach to a cantrip -spell = Cantrip(llm=llm, identity=identity, circle=circle, loom=loom) -``` - ---- - -## Mediums - -### Conversation (default) - -No medium specified. Gates appear as JSON tool calls — the LLM sees each gate as a separate tool definition. This is how most agent frameworks work. - -```python -Circle(gates=["done", "echo"], wards=[{"max_turns": 5}]) -``` - -### Code Medium - -The entity writes Python code that executes in-process via `exec()`. Gates are projected as host functions — `done()`, `call_gate()`, `call_entity()` — callable directly in the sandbox. Variables persist across turns. - -```python -Circle( - gates=["done", "repo_read"], - wards=[{"max_turns": 10}], - medium="code", -) -``` - -In the sandbox, the entity writes: - -```python -# Turn 1 -data = call_gate("repo_read", {"path": "metrics.txt"}) - -# Turn 2 — data persists from turn 1 -lines = data.split("\n") -done(f"Found {len(lines)} metrics") -``` - -The code medium uses `InProcessPythonExecutor` by default — Python's `exec()` with warded builtins and injected host functions. This gives the entity access to Python's full standard library within the sandbox, but isolation is best-effort (CPython threads can't be force-killed). For stronger isolation, use `SubprocessPythonExecutor`. - -### Browser Medium - -Adds browser automation via Playwright. Requires the `browser` optional dependency. - ---- - -## Composition - -The entity delegates via `call_entity` in code medium. Delegation is synchronous — the parent blocks while the child runs. - -```python -spell = Cantrip( - llm=parent_llm, - child_llm=child_llm, # optional: different LLM for children - circle=Circle( - medium="code", - gates=["done", "call_entity"], - wards=[{"max_turns": 6}, {"max_depth": 2}], - ), - identity=Identity( - system_prompt="Delegate tasks to children via call_entity.", - require_done_tool=True, - ), -) -``` - -Inside the code medium, the entity writes: - -```python -# call_entity is synchronous — blocks and returns the child's answer as a string -trends = call_entity({"intent": "Identify top 3 trends in this data..."}) -risks = call_entity({"intent": "What are the biggest risks..."}) -done(f"Trends: {trends}\nRisks: {risks}") -``` - -Children get a generic system prompt and independent context (COMP-4). Delegation gates are stripped from children to prevent recursive delegation. Child max_turns is capped at 3. - ---- - -## Examples - -Twelve examples in `examples/patterns/`, one for each grimoire pattern. Each example works in two modes: **scripted** (deterministic, no API key) and **real** (live LLM calls). - -| # | Pattern | What it teaches | -|---|---------|----------------| -| 01 | `llm_query` | LLM as stateless query | -| 02 | `gate` | Direct gate execution | -| 03 | `circle` | Construction invariants (done gate, wards) | -| 04 | `cantrip` | LLM + identity + circle = reusable script | -| 05 | `wards` | Subtractive composition (min for numeric, OR for boolean) | -| 06 | `medium` | Tool medium vs code medium — same gates, different action space | -| 07 | `full_agent` | Code medium + filesystem gates + error steering | -| 08 | `folding` | Context compression for long runs | -| 09 | `composition` | call_entity + call_entity_batch | -| 10 | `loom` | Inspect the append-only artifact | -| 11 | `persistent_entity` | summon/send across episodes | -| 12 | `familiar` | Persistent coordinator delegating through code | - -Run any example: -```bash -python examples/patterns/04_cantrip.py -``` - ---- - -## What You Can Learn Here - -**Strengths:** - -- **Readable code medium examples.** The Python examples are the clearest demonstration of the conversation-vs-code medium distinction. Example 06 shows the same gates producing different action spaces. Example 07 shows error steering in a code sandbox. -- **In-process Python sandbox.** The entity writes Python that runs via `exec()` with injected host functions. This is the most natural code medium if you're building in Python — the entity writes the same language as the host. -- **Clean API surface.** `Cantrip`, `Identity`, `Circle` — three classes, frozen dataclasses, no framework magic. The public API is 18 symbols. -- **SQLite loom storage.** The only implementation with SQLite as a loom backend (vs JSONL or in-memory). Good for persistent entities that need durable turn history. -- **Protocol adapters.** ACP (stdio), HTTP, and CLI adapters are all included and tested. - -**Limitations:** - -- **One LLM provider.** `OpenAICompatLLM` only — works with OpenAI, OpenRouter, and any OpenAI-compatible endpoint, but no native Anthropic or Google adapters. (The TS implementation has five providers.) -- **Two mediums.** Conversation and code (plus browser with optional Playwright). No bash, VM, or other substrate mediums. -- **In-process isolation only.** The default `InProcessPythonExecutor` uses `exec()` — no security boundary. `SubprocessPythonExecutor` is available but can't share gate functions across the process boundary. Neither is as isolated as QuickJS or node:vm. -- **`MiniCodeExecutor` is vestigial.** A minimal JS interpreter in Python, exported and tested but unlikely to be useful outside of cross-language test compatibility. - ---- - -## Spec Conformance - -Tests: **227 pass, 2 skip** (`uv run pytest tests/ -q`) - -The test suite includes: -- Core lifecycle tests (entity, cantrip, circle, loom) -- Medium behavior tests (tool and code) -- End-to-end delegation tests -- Grimoire example tests (all 12 patterns) -- Spec MUST-rule coverage test (regex scan of SPEC.md rules vs implementation) -- Protocol adapter tests (ACP, HTTP, CLI) - ---- - -## Setup - -Requires Python 3.11+. - -```bash -pip install -e . # or: uv pip install -e . -cp .env.example .env -``` - -Dependencies: `requests`, `PyYAML`, `agent-client-protocol`. No heavy ML frameworks. - -Set your API key: -```bash -OPENAI_API_KEY="sk-..." -OPENAI_MODEL="gpt-4.1-mini" -# Optional: -OPENAI_BASE_URL="https://api.openai.com/v1" -``` - -Run tests: -```bash -uv run pytest tests/ -q -``` diff --git a/py/SPEC.md b/py/SPEC.md deleted file mode 120000 index 269bfc79..00000000 --- a/py/SPEC.md +++ /dev/null @@ -1 +0,0 @@ -../SPEC.md \ No newline at end of file diff --git a/py/cantrip/__init__.py b/py/cantrip/__init__.py deleted file mode 100644 index 69e688b5..00000000 --- a/py/cantrip/__init__.py +++ /dev/null @@ -1,43 +0,0 @@ -from cantrip.acp_server import CantripACPServer -from cantrip.acp_stdio import ACPStdioRouter, serve_stdio, serve_stdio_once -from cantrip.adapters import cast_via_acp, cast_via_cli, cast_via_http -from cantrip.builders import build_cantrip_from_env -from cantrip.cli_runner import format_cli_json, run_cli -from cantrip.entity import Entity -from cantrip.errors import CantripError -from cantrip.executor import InProcessPythonExecutor, MiniCodeExecutor, SubprocessPythonExecutor -from cantrip.http_router import CantripHTTPRouter -from cantrip.loom import InMemoryLoomStore, Loom, SQLiteLoomStore -from cantrip.models import Identity, Circle -from cantrip.providers.base import LLM -from cantrip.providers.fake import FakeLLM -from cantrip.providers.openai_compat import OpenAICompatLLM -from cantrip.runtime import Cantrip -

implementation. The richest surface for mediums, examples, and the full API. - -This is the TypeScript realization of the cantrip spec. It was the original experimental playground — built up iteratively, then backported to the spec's domain model after SPEC.md was written. It has the most mediums, the most examples, and the most complete coverage of the spec's behavioral rules. If you want to understand how cantrip works by reading code, start here. - -For the full vocabulary and behavioral rules, see [SPEC.md](../SPEC.md) at the repo root. - ---- - -## Quick Start - -```bash -cd ts -bun install -cp .env.example .env # add your API key -``` - -Run the simplest meaningful example — a cantrip with an LLM, an identity, a circle, and an intent: - -```bash -bun run examples/04_cantrip.ts -``` - -Once the vocabulary clicks, try the capstone — a persistent entity that constructs and casts child cantrips from code: - -```bash -bun run examples/16_familiar.ts -``` - ---- - -## Minimal Example - -An LLM, a circle with gates and wards, and an identity — assembled into a cantrip and cast on an intent. - -```typescript -import { cantrip, Circle, ChatAnthropic, done, max_turns, gate } from "cantrip"; - -// LLM — a language model provider -const llm = new ChatAnthropic({ model: "claude-sonnet-4-5" }); - -// A gate — a function the entity can call -const add = gate("Add two numbers", async ({ a, b }: { a: number; b: number }) => a + b, { - name: "add", - params: { a: "number", b: "number" }, -}); - -// Circle — gates + wards (constraints) -const circle = Circle({ - gates: [add, done], - wards: [max_turns(10)], -}); - -// Cantrip — llm + identity + circle -const spell = cantrip({ - llm, - identity: "You are a calculator. Use the add tool, then call done with the result.", - circle, -}); - -// Cast it on an intent -const result = await spell.cast("What is 2 + 3?"); -console.log(result); // "5" -``` - -Each `cast` creates a fresh entity — the cantrip is a reusable script. No medium specified here: the circle uses **conversation** by default, where gates appear as tool calls in natural language. Add a medium to upgrade the entity's action space. - ---- - -## Core Concepts - -### LLM (Cognition) - -An LLM wraps a language model provider. It takes messages and tools, returns a response. Stateless — each query is independent. - -```typescript -import { ChatAnthropic } from "cantrip"; - -const llm = new ChatAnthropic({ model: "claude-sonnet-4-5" }); -const result = await llm.query([ - { role: "user", content: "What is 2 + 2? Reply with just the number." }, -]); -console.log(result.content); // "4" -``` - -Multiple providers: `ChatAnthropic`, `ChatOpenAI`, `ChatGoogle`, `ChatOpenRouter`, `ChatLMStudio`. - -### Identity (Invocation) - -The identity shapes the entity's behavior — a system prompt plus any hyperparameters. It can be a string or an object: - -```typescript -// String shorthand -cantrip({ llm, identity: "You analyze code for bugs.", circle }); - -// Object form -cantrip({ - llm, - identity: { system_prompt: "You analyze code for bugs." }, - circle, -}); -``` - -Gate definitions are automatically derived from the circle — you don't wire them manually. - -### Circle (Control) - -A circle is the entity's capability envelope: **medium + gates + wards**. - -```typescript -import { Circle, done, max_turns, require_done } from "cantrip"; - -const circle = Circle({ - gates: [done], - wards: [max_turns(10)], -}); -``` - -Every circle must have a `done` gate (how the entity signals completion) and at least one ward (how the host prevents infinite loops). This is enforced at construction time. - -**Gates** are functions bound into the circle from outside. The entity calls them as tools: -- `done` — signals task completion via `submit_answer(result)` -- Custom gates — any function you define with `gate()` -- Builtin sets — `safeFsGates` (filesystem), `repoGates` (repo observation), `cantripGates` (child cantrip construction) - -**Wards** are constraints on the loop: -- `max_turns(n)` — limit loop iterations -- `require_done()` — only explicit `done` terminates (text-only responses don't stop the loop) - -### Entity (Emergence) - -An entity is what arises when you cast a cantrip on an intent. You don't build it — it emerges from the loop. It accumulates context, develops strategies, and adapts turn by turn. - -Two ways to create one: - -```typescript -// Cast — one-shot. Entity runs, returns result, disposes. -const result = await spell.cast("Analyze this data"); - -// Summon — persistent. Entity survives, accepts more intents. -const entity = spell.summon(); -const r1 = await entity.send("First task"); -const r2 = await entity.send("Follow-up task"); // remembers r1 -``` - -For interactive sessions, use `summon()` with the built-in REPL: - -```typescript -import { runRepl } from "cantrip"; - -const entity = spell.summon(); -await runRepl({ - entity, - greeting: "Agent ready. Ctrl+C to exit.", -}); -``` - ---- - -## Mediums - -A **medium** is the substrate the entity works in. When no medium is specified, the circle uses **conversation** — the baseline where gates appear as tool calls in natural language. Add a medium to upgrade the entity's action space. - -One medium per circle. The medium replaces conversation — it doesn't sit alongside it. The entity works *in* the medium, not through it. - -### Conversation (default) - -No medium specified. The entity communicates in natural language and uses gates as tool calls. This is how most chat-based agents work. - -```typescript -const circle = Circle({ - gates: [...safeFsGates, done], - wards: [max_turns(100)], -}); -``` - -### VM (node:vm sandbox) - -The entity writes and runs JavaScript in a node:vm context. Full ES2024 — arrow functions, async/await, destructuring. Zero external dependencies. Gates are projected as async functions the entity calls with `await`. - -```typescript -import { vm } from "cantrip"; - -const circle = Circle({ - medium: vm({ state: { context: { items: [1, 2, 3] } } }), - wards: [max_turns(20), require_done()], -}); -``` - -The entity sees a `context` variable in its sandbox and explores it with code. `var` and `globalThis` persist across turns. Weak isolation (V8 context, not a security boundary). - -### JavaScript (QuickJS sandbox) - -The entity works in a QuickJS WASM sandbox. Strong isolation but limited ES version and a serialization boundary — gate results are strings, not native objects. - -```typescript -import { js } from "cantrip"; - -const circle = Circle({ - medium: js({ state: { context: { items: [1, 2, 3] } } }), - wards: [max_turns(20), require_done()], -}); -``` - -### Bash - -The entity writes shell commands. Full access to CLI tools — git, curl, ffmpeg, jq, whatever's installed. - -```typescript -import { bash } from "cantrip"; - -const circle = Circle({ - medium: bash({ cwd: "/project" }), - wards: [max_turns(10)], -}); -``` - -### Browser (Taiko) - -The entity controls a headless browser by writing Taiko code — navigation, clicking, data extraction. - -```typescript -import { browser } from "cantrip"; - -const circle = Circle({ - medium: browser({ headless: true, profile: "full" }), - wards: [max_turns(50), require_done()], -}); -``` - -### jsBrowser - -JS sandbox with browser automation combined — the entity writes JavaScript that can also control a browser. - -```typescript -import { jsBrowser, BrowserContext } from "cantrip"; - -const browserCtx = await BrowserContext.create({ headless: true, profile: "full" }); -const circle = Circle({ - medium: jsBrowser({ browserContext: browserCtx }), - wards: [max_turns(200), require_done()], -}); -``` - -### Other mediums - -Any interactive environment can become a medium — Python, SQL, Frida, GDB, Redis, or a custom DSL. The interface is the same: the entity writes, the medium executes, the result feeds back. - ---- - -## Patterns - -### One-shot cast - -The simplest pattern. Create a cantrip, cast it, get a result. - -```typescript -import { cantrip, Circle, ChatAnthropic, js, max_turns, require_done } from "cantrip"; - -const spell = cantrip({ - llm: new ChatAnthropic({ model: "claude-sonnet-4-5" }), - identity: "Explore the context variable. Use submit_answer() when you have a final answer.", - circle: Circle({ - medium: js({ state: { context: { items: ["alpha", "beta", "gamma"] } } }), - wards: [max_turns(20), require_done()], - }), -}); - -const answer = await spell.cast("Which item comes first alphabetically?"); -``` - -### Persistent REPL - -For interactive sessions — the entity remembers across intents. - -```typescript -import { runRepl, safeFsGates, getSandboxContext, SandboxContext } from "cantrip"; - -const fsCtx = await SandboxContext.create(); - -const entity = cantrip({ - llm, - identity: `Coding assistant. Working dir: ${fsCtx.working_dir}`, - circle: Circle({ - gates: [...safeFsGates, done], - wards: [max_turns(100)], - }), - dependency_overrides: new Map([[getSandboxContext, () => fsCtx]]), -}).summon(); - -await runRepl({ entity, greeting: "Agent ready." }); -``` - -### Recursive delegation - -A parent entity in a JS medium delegates subtasks to children via `call_entity`. - -```typescript -import { call_entity_gate, Loom, MemoryStorage, js } from "cantrip"; - -const entityGate = call_entity_gate({ max_depth: 2, depth: 0, parent_context: data }); - -const circle = Circle({ - medium: js({ state: { context: data } }), - gates: entityGate ? [entityGate] : [], - wards: [max_turns(20), require_done()], -}); - -const loom = new Loom(new MemoryStorage()); -const spell = cantrip({ llm, identity: "Delegate analysis to child entities.", circle, loom }); -const answer = await spell.cast("Analyze each category and summarize the trend."); -``` - -Children get independent circles. `call_entity` is synchronous from the parent's perspective — the parent blocks while the child runs and receives the result as a return value. The shared loom captures parent + child turns as a tree. - -### The Familiar - -The capstone pattern: a long-running entity in a `vm()` medium that creates and casts child cantrips from code. It observes the repo, delegates to specialized children (bash, browser, JS), and synthesizes results. - -```typescript -import { - cantripGates, repoGates, RepoContext, Loom, JsonlStorage, done, - vm, js, bash, browser, getRepoContextDepends, -} from "cantrip"; - -const loom = new Loom(new JsonlStorage(".cantrip/loom.jsonl")); -await loom.load(); - -const cantripConfig = { - mediums: { - bash: (opts) => bash({ cwd: opts?.cwd ?? repoRoot }), - js: (opts) => js({ state: opts?.state }), - vm: (opts) => vm({ state: opts?.state }), - browser: () => browser({ headless: true, profile: "full" }), - }, - gates: { done: [done] }, - default_wards: [{ max_turns: 15 }], - loom, -}; - -const { gates: cGates, overrides: cOverrides } = cantripGates(cantripConfig); -const repoCtx = new RepoContext(repoRoot); - -const circle = Circle({ - medium: vm(), - gates: [...repoGates, ...cGates], - wards: [max_turns(50), require_done()], -}); - -const spell = cantrip({ - llm, - identity: SYSTEM_PROMPT, - circle, - dependency_overrides: new Map([ - [getRepoContextDepends, () => repoCtx], - ...cOverrides, - ]), - loom, - folding_enabled: true, -}); -``` - -Inside the Familiar's vm medium, the entity writes modern JS to coordinate: - -```javascript -// Shell work — child runs in bash -const worker = cantrip({ - llm: "anthropic/claude-haiku-4.5", - identity: "Execute the command and report output.", - circle: { medium: "bash", gates: ["done"], wards: [{ max_turns: 5 }] } -}); -const output = await cast(worker, "Run the test suite"); - -// Thinking — leaf cantrip, single LLM call -const thinker = cantrip({ llm: "anthropic/claude-haiku-4.5", identity: "Analyze code." }); -const analysis = await cast(thinker, "What bugs do you see?\n" + code); - -// Compose in code — loops, conditionals, pipelines -const files = JSON.parse(await repo_files("src/**/*.ts")); -for (const file of files) { - const src = await repo_read(file); - if (src.includes("TODO")) { - const review = await cast( - cantrip({ llm: "anthropic/claude-haiku-4.5", identity: "Find TODOs." }), - src - ); - console.log(file + ": " + review); - } -} -``` - -See `examples/16_familiar.ts` for the full implementation. - ---- - -## The Loom - -Every turn is recorded in a **loom** — a structured log that captures the entity's full execution history as a tree of turns. - -```typescript -import { Loom, JsonlStorage, MemoryStorage } from "cantrip"; - -// In-memory (ephemeral) -const loom = new Loom(new MemoryStorage()); - -// Persistent to disk -const loom = new Loom(new JsonlStorage(".cantrip/loom.jsonl")); -await loom.load(); -``` - -The loom records whether each thread **terminated** (entity called `done`) or was **truncated** (ward triggered). This distinction matters: terminated threads are complete episodes, truncated threads are interrupted ones. - -**Folding** compresses old turns to keep the entity's context window manageable while preserving key information. It reads from the loom and writes compressed summaries back into the entity's working state. - ---- - -## Examples - -The `examples/` directory walks through the concepts in order. Each example builds on the previous ones — the progression is the curriculum. - -| # | Example | What it teaches | -|---|---------|----------------| -| 01 | `llm` | LLM as stateless query | -| 02 | `gate` | Defining callable functions | -| 03 | `circle` | Gates + wards + validation | -| 04 | `cantrip` | LLM + identity + circle = script | -| 05 | `ward` | Constraints and safety limits | -| 06 | `providers` | Multi-provider LLMs | -| 07 | `conversation` | Conversation medium (default) | -| 08 | `js_medium` | QuickJS sandbox | -| 09 | `browser_medium` | Taiko browser automation | -| 10 | `composition` | Parallel delegation via call_entity_batch | -| 11 | `folding` | Context compression | -| 12 | `full_agent` | JS medium + filesystem gates | -| 13 | `acp` | Agent Client Protocol adapter | -| 14 | `recursive` | Depth-limited recursive entities | -| 15 | `research_entity` | jsBrowser + recursion + ACP | -| 16 | `familiar` | Cantrip construction as medium physics | -| 17 | `leaf_cantrip` | Simplest delegation — llm + identity, one LLM call | -| 18 | `vm_medium` | node:vm sandbox — full ES2024, async/await | -| 19 | `bash_medium` | Entity works IN bash as primary medium | -| 20 | `data_exploration` | RLM pattern — data in sandbox, explore with code | -| 21 | `independent_axes` | M, G, W as orthogonal knobs | - -Run any example: -```bash -bun run examples/04_cantrip.ts -``` - ---- - -## What You Can Learn Here - -This is the reference implementation — the most complete realization of the spec. It has things the other implementations don't: - -- **Five mediums** (conversation, VM, QuickJS, bash, browser) — see the spec's medium concept expressed in multiple substrates -- **21 examples** — the fullest progression from raw LLM query to familiar -- **Dependency injection via `Depends`** — a pattern for wiring gate dependencies without coupling -- **Ephemeral gate tuning** — mark gate results as ephemeral to save context space -- **The gate decorator API** — both high-level (`gate()`) and low-level (`rawGate()`) interfaces - -It is also the least portable. It depends on Bun, QuickJS WASM bindings, Taiko, and node:vm. If you want a cleaner starting point for your own implementation, the Python or Elixir versions may be easier to read and adapt. - ---- - -## Spec Conformance - -Tests: **615 pass, 55 skip** (`bun test --timeout 30000`) - -The skipped tests are primarily integration tests that require API keys or specific runtime conditions. Core behavioral rules are fully covered. - -Provider support: Anthropic, OpenAI, Google, OpenRouter, LMStudio — the broadest of the four implementations. - ---- - -## Setup - -```bash -bun install -cp .env.example .env -# Edit .env with your API key(s) -``` - -Set at least one provider: -```bash -ANTHROPIC_API_KEY="sk-..." -# or -OPENAI_API_KEY="sk-..." -# or -OPENROUTER_API_KEY="sk-..." -``` - -Run the test suite: -```bash -bun test --timeout 30000 -``` - ---- - -## License - -MIT diff --git a/ts/SPEC.md b/ts/SPEC.md deleted file mode 120000 index 269bfc79..00000000 --- a/ts/SPEC.md +++ /dev/null @@ -1 +0,0 @@ -../SPEC.md \ No newline at end of file diff --git a/ts/TESTING.md b/ts/TESTING.md deleted file mode 100644 index af47780b..00000000 --- a/ts/TESTING.md +++ /dev/null @@ -1,164 +0,0 @@ -# Testing - -## Running Tests - -```bash -bun test -``` - -This runs unit tests (offline, mocked), spec tests (behavioral rules from SPEC.md), and integration tests (live API calls).

Highlights: - Remove legacy multi-version learning-repo surfaces from the package shape. - Define the Elixir public API around cantrips, entities, circles, gates, wards, looms, Familiar, and ACP. - Make ReqLLM the provider adapter and depend on req_llm ~> 1.12. - Default the code medium/Familiar path to the port-isolated Dune child-BEAM runtime. - Preserve explicit escape hatches for trusted unrestricted execution. - Add package docs, deployment docs, public API guide, migration guide, audit notes, Livebook, and changelog. - Add release CI for docs, Hex package build, signer policy, and live Anthropic checks on main/release/tag pushes. Pre-tag fixes included: - Streaming tool calls now survive streamed ReqLLM responses. - Persistent entities preserve assistant turns across Cantrip.send/2. - Folding preserves all leading system messages plus original intent. - Anthropic multi-system handling is covered by ReqLLM 1.12. - Live Anthropic validation passed across haiku, sonnet, and opus. --- .github/workflows/verify.yml | 47 +-

The patterns of force are aligned. Now it is up to your machine." -> -> — Gargoyles: Reawakening (1995) - -**Version**: 0.3.1 -**Status**: Draft — behavioral rules for implementation - -## Introduction - -A cantrip is a spell. In fantasy games, it refers to the simple starter spells that come in your spellbook at level 1. The etymology is thought to be related to Gaelic "Canntaireachd", a piper's mnemonic chant. It's a loop of language. - -This is a starter spellbook. It describes a method for creating spells using the tools of modern summoning: a language model, a computer, and a prompt. It's language loops all the way down. - -A language model takes text in and gives text back. One pass — no memory, no consequences. To make it do things, you close the loop: take the model's output, run it in an environment, and let it observe the effects. The environment pushes back: code runs or crashes, files exist or don't, tests pass or fail. Turn by turn, the model accumulates experience. It starts doing things its designers never enumerated, because the action space is a programming language and programming languages are compositional. - -That's the shape: call and response. You draw a circle, you speak into it, something answers. Each turn through the loop brings the model closer to the task or reveals why the task is harder than it looked. - -This spellbook gives names to the parts of that loop. Three are fundamental: the **LLM** (the model), the **identity** (the immutable configuration that shapes it), and the **circle** (the environment it acts in). The LLM thinks. The identity tells it who it is. The circle is where it acts. Everything else is what happens when you put those three together and let the loop run. - -The circle has an interior and a boundary. The interior is the **medium** — the substrate the entity works *in*. Think of it like an artist's medium: oil, marble, code. The boundary is crossed by **gates** — host functions that reach the outside world. **Wards** constrain what is possible — turn limits, resource caps, scope restrictions. The entity's action space is the medium's primitives, plus the registered gates, minus whatever the wards restrict: A = M ∪ G − W. - -The **loom** records every turn. The entity is transient; the loom is durable. It is simultaneously the debugging trace, the training data, and the substrate for replay, forking, and persistence across casts. - -The same pattern works at every scale. The simplest cantrip is an LLM in a loop with one gate (`done`) and a turn limit. The most complex is a tree of entities with recursive composition, a loom feeding comparative reinforcement learning, and circles nested inside circles. Same vocabulary, different configuration. Any implementation that passes the accompanying test suite (`tests.yaml`) is a valid cantrip. Terms are defined in context as they appear; the Glossary at the end is for quick reference. - ---- - -## Chapter 1: The Loop - -Everything in this document — every term, every rule, every architectural decision — exists to give structure to one idea: a model acting in a loop with an environment. The loop is the foundation. Start here. - -### 1.1 The turn - -Each cycle through the loop is called a **turn**. A turn has two halves. - -First, the **entity** — the running instance of the model inside the loop — produces an **utterance**: text that may contain executable code or structured calls to the environment. Then the **circle** — the environment — executes what the entity wrote and produces an **observation**: a single composite object containing an ordered list of results, one entry per gate call, plus sandbox output if applicable. The observation feeds into the next turn as one unit. State accumulates. - -``` -LOOP-1: The loop MUST alternate between entity utterances and circle observations. Two consecutive entity utterances without an intervening observation MUST NOT occur. -``` - -This strict alternation is what makes the loop a loop and not a monologue. The entity acts, the world responds, the entity acts again with the world's response in hand. - -The script that defines the loop — which model, which configuration, which environment — is called a **cantrip**. The goal the entity is pursuing is called an **intent**. Both get their own treatment later. For now, what matters is the cycle: act, observe, repeat. - -Closing the loop is what transforms a predictor into an actor. When outputs influence subsequent inputs, the system transitions from passive prediction to world-shaping action. The model's completions change the environment, the changed environment changes the next prompt, and the model adjusts. The loop is the mechanism by which a generative model becomes something that acts. - -### 1.2 What the entity perceives - -On every turn, the entity needs to know two things: what it's supposed to do, and what has happened so far. - -The **identity** — the immutable configuration that shapes the model's behavior — and the **intent** — the goal — are always present. Think of them as the entity's fixed orientation: who it is, and what it's after. Those never change. - -Everything beyond that is mediated by the circle. In the simplest design, the circle presents the full history of prior turns as a growing message list. In a code circle, the entity can access state through code instead: reading variables, querying data structures, inspecting files that persist between turns. Both are valid. What the entity sees is the circle's decision. - -``` -LOOP-5: The entity MUST receive the identity and the intent on every turn. How prior turns are presented — as a message history, as program state, or as a combination — is determined by the circle's design. The circle mediates what the entity perceives. -``` - -### 1.3 Termination and truncation - -Every loop ends. The question is how, and the answer matters more than you might expect. - -**Terminated** means the entity called the `done` gate — a special exit point that signals "I believe the task is complete." The entity chose to stop. In a code circle, the done gate is projected into the medium as `submit_answer` — the entity calls `submit_answer(result)` in code, and the medium translates this into the done gate on the entity's behalf. - -**Truncated** means a **ward** cut the entity off. A ward is a restriction on the loop — a maximum number of turns, a timeout, a resource limit. The environment chose to stop. The entity was interrupted, not finished. - -``` -LOOP-2: The loop MUST terminate. Every cantrip MUST have the `done` gate (CIRCLE-1) AND at least one truncation condition (a max turns ward). When `require_done_tool` is false, text-only responses also terminate — but the done gate must still be present. -``` - -``` -LOOP-3: When the `done` gate is called, the loop MUST stop after processing that gate. Any remaining gate calls in the same utterance MAY be skipped. -``` - -``` -LOOP-4: When a ward triggers truncation, the loop MUST stop. The implementation SHOULD generate a summary of what was accomplished before the entity was cut off. -``` - -The `require_done_tool` ward controls what happens when the entity produces a text-only response — no code, no gate calls, just words. When false (the default), a text-only response terminates the loop. When true, only an explicit `done` gate call terminates. This is a ward, not an identity property — it constrains the loop, and it composes with OR across parent and child circles (WARD-1). - -``` -LOOP-6: If `require_done_tool` is false (default) and the entity produces a text-only response (no gate calls), the loop MUST treat that as implicit termination. If `require_done_tool` is true, a text-only response MUST NOT terminate the loop — only a `done` gate call terminates. -``` - -``` -LOOP-7: If a `done` gate call is malformed (missing required arguments) or returns an error, the loop MUST NOT mark the turn as terminated. The failure MUST be returned as an observation and normal ward/truncation rules continue to apply. -``` - -Why does the terminated/truncated distinction matter? Because it travels with the data. A terminated thread is a completed episode — training data with a natural endpoint. A truncated thread is an interrupted episode — the entity's final state shouldn't be treated as a conclusion because it wasn't one. Implementations MUST record which occurred. - -### 1.4 The cantrip, the intent, and the entity - -A **cantrip** is the script that produces the loop. It binds an LLM to a circle through an identity — which model, which configuration, which environment. A cantrip is a value, not a running process. You write it once and cast it many times. - -``` -CANTRIP-1: A cantrip MUST contain an LLM, an identity, and a circle. Missing any of these is invalid. -``` - -``` -CANTRIP-2: A cantrip is a value. It MUST be reusable — casting it multiple times on different intents MUST produce independent entities. -``` - -An **intent** is the reason the loop runs — the goal, the task, the thing the entity is trying to achieve. Same cantrip, different intent, different episode. - -``` -INTENT-1: The intent MUST be provided when casting a cantrip. A cantrip cannot be cast without an intent. -``` - -``` -INTENT-2: The intent MUST appear as the first user message in the entity's context, after the system prompt (if any). -``` - -``` -INTENT-3: The intent is immutable for the lifetime of a cast. The entity cannot change its own intent mid-episode. A summoned entity may receive new intents as subsequent casts (ENTITY-5). -``` - -And the **entity** is what appears when you cast a cantrip on an intent and the loop starts running. This is the one that's hard to pin down, because you don't build it — it arises. - -Watch what happens after a few turns. - -The LLM's output on turn twelve doesn't look like its output on turn one. It's referencing variables it created on turn four. It's working around an error it hit on turn seven. It's pursuing a strategy that emerged from something it noticed on turn nine — a pattern in the data that nobody told it to look for. The identity didn't ask for this strategy. The circle didn't suggest it. It appeared in the space between them, born from the accumulation of action and observation. - -This is the entity. Not a thing you built — a thing that arose. The LLM is the same LLM it was before the loop started. The identity hasn't changed. The circle is just an environment, doing what environments do. But the process running through all three of them has developed something like perspective. It has context. It has momentum. It has preferences shaped by what it's tried and what worked. - -You didn't design the entity. You designed the LLM, the identity, and the circle. The entity is what happened when you put them together and let the loop run. - -It will exist for as long as the loop runs. When the loop stops — task complete, budget exhausted, ward triggered — the entity is gone. The LLM remains, unchanged. The circle can be wiped or preserved. But the entity, that particular accumulation of context and strategy and in-context learning, is over. - -Unless you recorded it. But that's a later chapter. - -``` -ENTITY-1: An entity MUST be produced by a cantrip — either by casting (one-shot) or by summoning (persistent). There is no other way to create an entity. -``` - -``` -ENTITY-2: Each entity MUST have a unique ID. Implementations MUST auto-generate a unique entity ID if one is not provided by the caller. -``` - -``` -ENTITY-3: An entity's state MUST grow monotonically within a thread (modulo folding, which is a view transformation, not deletion — see Chapter 6). -``` - -``` -ENTITY-4: When an entity terminates or is truncated, its thread persists in the loom. The entity ceases but its record endures. -``` - -Summoning a cantrip produces a persistent entity. The initial intent starts the loop. When the loop completes — done or truncated — the entity persists. You can provide another intent as a new cast, and the loop resumes with accumulated state. - -Casting is a convenience: summon, run one intent, return the result, discard the entity. Most examples in this document describe casting, because most tasks are one-shot. But the underlying mechanism is always summoning — casting is just summoning with automatic cleanup. - -``` -ENTITY-5: A summoned entity persists after its loop completes. It MAY receive additional intents as new casts. State accumulates across all casts. -``` - -``` -ENTITY-6: Summoning a cantrip multiple times MUST produce independent entities, just as casting does (CANTRIP-2). -``` - -The LLM, the identity, and the circle each have their own chapters. The entity does not, because the entity is not a component you configure. It is what emerges from the components you did configure, once the loop begins. - -### 1.5 The four temporal levels - -Four verbs, four timescales. - -**Query** is the atomic unit. One round-trip to the LLM: messages in, response out. The LLM is stateless, so each query is independent. - -**Turn** is one cycle of the loop. The entity produces an utterance, the circle executes it and returns an observation. A turn is the atom of experience — the smallest unit that has both action and consequence. - -**Cast** is one complete episode. A cantrip is cast on an intent, the loop runs until `done` or a ward triggers, and a result comes back. - -**Summon** creates a persistent entity. The entity survives the completion of its first intent. You can send it additional intents, and the loop resumes with accumulated state. - -These nest cleanly: a summon contains one or more casts, a cast contains one or more turns, a turn contains one or more queries. The nesting is strict — a query never spans turns, a turn never spans casts. - -### 1.6 The RL correspondence - -If you know reinforcement learning, this table shows how the vocabulary maps. If you don't, skip ahead — the spec teaches everything you need without it. The mapping is structural, not formal — these are parallels that help you reason about the system, not mathematical equivalences. - -| RL concept | Cantrip equivalent | Notes | -|-----------|-------------------|-------| -| Policy | LLM + Identity | Frozen weights conditioned by immutable identity | -| Goal specification | Intent | The desire that shapes which actions are good | -| State s | Circle state | Accessed through gates | -| Action a | Code the entity writes | A = M ∪ G − W | -| Observation o | Gate return values + sandbox output | Rich, unstructured | -| Reward r | Implicit or explicit | Gate success/failure; verifier scores; thread ranking | -| Terminated | `done` gate called | Entity chose to stop | -| Truncated | Ward triggered | Environment chose to stop | -| Trajectory | Thread | One root-to-leaf path through the loom | -| Episode | Cast | One cast: intent in, result out | -| Replay buffer | Loom | Tree structure provides comparative RL data | -| Environment reset | New entity, clean circle | Forking is NOT a reset — it continues from prior state | - -The loom's relationship to modern RL methods is developed fully in Chapter 6. - -### 1.7 A complete example - -All the pieces in one place. A file-processing task: count the words in every `.txt` file in a directory and report the total. - -**The cantrip.** LLM: any model that supports tool calling. Identity: "You are a file-processing assistant. Use code to solve tasks efficiently." Circle: a code medium with three gates — `read(path) -> string`, `list_dir(path) -> string[]`, and `done(answer)` — a ward of max 10 turns, and `require_done_tool: true`. Filesystem root: `/data`. - -**The intent.** "Count the total number of words across all .txt files in /data and return the count." - -**Turn 1.** The entity appears, receives identity and intent, and produces: -``` -const files = list_dir("/data"); -``` -Observation: `GateCallRecord { gate_name: "list_dir", arguments: '{"path":"/data"}', result: '["a.txt", "b.txt", "c.txt"]', is_error: false }`. - -**Turn 2.** The entity reads all files: -``` -const a = read("/data/a.txt"); -const b = read("/data/b.txt"); -const c = read("/data/c.txt"); -``` -Three `GateCallRecord` objects, each with `is_error: false` and file contents. - -**Turn 3.** The entity counts and terminates: -``` -const total = [a, b, c] - .map(text => text.split(/\s+/).filter(w => w.length > 0).length) - .reduce((sum, n) => sum + n, 0); -done(total); -``` -Loop terminates with result 1547. - -**The loom.** Three turns, one thread. Each turn records token usage, duration, utterance, and observation. The thread is terminated — a complete episode usable as training data, a debugging trace, or a template for forking. - -**Error as steering.** Same cantrip, but `/data/b.txt` does not exist. Turn 2's observation for `b` returns `is_error: true` with `'ENOENT: no such file or directory'`. Turn 3: the entity sees the error and adapts — counts only `a` and `c`, reports `{ total: 1200, note: "b.txt not found, counted 2 of 3 files" }`. The error did not stop the entity. It steered it. - ---- - -## Chapter 2: The LLM - -The LLM is the model. You send it messages, it sends back a response. That is the entire interface — and the simplicity is the point. - -An LLM does not act on its own. It has no memory between queries, no persistent state. You send it a list of messages and it sends back text, structured gate calls, or both. Then it's done. The next time you query it, you must send everything again. The LLM does not remember that there was a last time. - -``` -LLM-1: An LLM MUST be stateless. Given the same messages and tool definitions, it SHOULD produce similar output (modulo sampling). It MUST NOT maintain internal state between queries. -``` - -This statelessness is the contract, not a limitation. Everything that makes an entity seem to learn across turns comes from the loop feeding the LLM's own prior output back as input. The learning lives in the loop, not in the LLM. - -### 2.1 The LLM contract - -``` -llm.query(messages: Message[], tools?: ToolDefinition[], tool_choice?: ToolChoice, extra?: Record) -> Response -``` - -The inputs: -- `messages` — an ordered list of messages (system, user, assistant, tool). -- `tools` — an optional list of gate definitions, expressed as JSON Schema. -- `tool_choice` — controls whether the LLM must use gates ("required"), may use them ("auto"), or must not ("none"). -- `extra` — optional provider-specific parameters passed through to the underlying API. - -The response contains: -- `content` — text output (may be null if the LLM only made gate calls) -- `tool_calls` — an optional list of gate invocations, each with an ID, gate name, and JSON arguments -- `usage` — token counts (prompt, completion, cached) -- `thinking` — optional reasoning trace (for models that support extended thinking) - -``` -LLM-2: An LLM MUST accept messages up to its provider's context limit. When input exceeds that limit, the LLM SHOULD return a structured error (not silently truncate). In practice, context limit errors may come from the provider API rather than from a pre-check — folding (§6.8) is the primary mechanism for staying within limits. -``` - -``` -LLM-3: An LLM MUST return at least one of `content` or `tool_calls`. A response with neither is invalid. -``` - -``` -LLM-4: Each `tool_call` MUST include a unique ID, the gate name, and arguments as a JSON string. -``` - -``` -LLM-5: If `tool_choice` is "required", the LLM MUST return at least one tool call. If the provider doesn't support forcing tool use, the implementation SHOULD simulate it (e.g., by re-prompting). Implementations MAY rely on provider-native support for forced tool use where available. -``` - -### 2.2 The swap - -Take a working cantrip and replace the LLM. Keep everything else — the circle, the identity, the gates, the wards, the intent. The entity that appears behaves differently. It reasons differently, makes different mistakes, pursues different strategies. The LLM is the one component you swap to change how the entity thinks without changing what it can do or where it acts. - -### 2.3 Provider implementations - -In practice, LLMs come from different providers with different APIs. The spec requires support for at least: **Anthropic** (Claude), **OpenAI** (GPT), **Google** (Gemini), **OpenRouter** (proxy), and **Local** (LM Studio,vLLM, any OpenAI-compatible endpoint). - -``` -LLM-6: Provider implementations MUST normalize responses to the common LLM contract. Provider-specific fields MAY be preserved as metadata but MUST NOT be required by consumers. -``` - -``` -LLM-7: In providers that require tool-call/result pairing, implementations MUST preserve call-result linkage exactly (including tool call IDs and ordering). Adapters MUST NOT emit tool-result messages unless the preceding assistant message contained matching tool calls. -``` - ---- - -## Chapter 3: The Identity - -The LLM is a function. The identity is what you pass to it — or more precisely, the part that stays the same every time you pass it. The identity is everything that shapes the LLM's behavior before any intent arrives. - -``` -IDENTITY-1: The identity MUST be set at cantrip construction time and MUST NOT change afterward. -``` - -### 3.1 What the identity contains - -The identity is the union of two things: - -1. **System prompt** — persona, behavioral directives, domain knowledge. -2. **Hyperparameters** — temperature, top_p, max_tokens, stop sequences, sampling configuration. - -The LLM needs to know what gates are available — but that knowledge comes from the circle, not the identity. The circle registers gates, executes them, and presents them to the LLM as tool definitions at query time. The identity stays small and separable: the same identity can work in different circles with different gate sets. - -``` -IDENTITY-3: Gate definitions are the circle's responsibility. The circle MUST present its registered gates to the LLM as tool definitions at query time. The identity carries rendered gate definitions produced by the circle for transport convenience, but the circle remains the authority for what gates exist. The circle — not the identity — registers, executes, and presents gates. -``` - -### 3.2 Immutability and identity - -The identity is fixed. You can create a new cantrip with a different identity, but you can't mutate an existing one. This gives you clean axes of variation: - -Same LLM + different identity = different entity behavior. Same LLM + same identity + different circle = different capabilities. Same everything + different intent = different episode. - -``` -IDENTITY-2: If a system prompt is provided, it MUST be the first message in every context sent to the LLM. It MUST be present in every query, unchanged. -``` - -### 3.3 What the identity is not - -Context belongs in the environment, not in the prompt. Dynamic context — retrieved documents, injected state, programmatic insertions that change per turn — is circle state, accessed through gates. A cantrip that processes a thousand documents places them in the circle as data the entity can read, query, and navigate through code. The identity tells the entity who it is. The circle contains what it works with. The identity doesn't grow. The circle does. - -### 3.4 The identity in the loom - -``` -IDENTITY-4: The identity MUST be stored in the loom as the root context. Every thread starts from the same identity. -``` - -``` -IDENTITY-5: Folding (context compression) MUST NOT alter the identity. The entity always retains its full identity. Only the trajectory (turns) may be folded. -``` - ---- - -## Chapter 4: The Circle - -The LLM thinks. The identity shapes. The circle is where the entity acts. - -### 4.1 What a circle is - -A circle is anything that receives the entity's output and returns an observation. Every circle has an interior and a boundary. The interior is the **medium** — the substrate the entity works *in*. The boundary is crossed by **gates** and constrained by **wards**. - -The medium matters more than it might seem. It determines what the entity is doing when it acts — not what it calls out to, but what it thinks *in*. Conversation, code, a shell, a browser, a proof assistant. The medium is the inside of the circle. - -Circles exist on a spectrum of expressiveness determined by their medium. - -A **conversation circle** uses natural language as its medium. The simplest case is a human circle — you are the environment, the entity speaks, you respond. But conversation is also the medium when two models talk to each other, or when a model talks to a human through a chat interface. The action space is whatever the model can say: A is just language. This is already a complete medium. Not every task needs code. - -A **tool-calling circle** adds gates to conversation. The entity invokes JSON functions — `read`, `fetch`, `search` — and receives structured results. The medium is still conversation, but the boundary now has crossing points. The action space is the gate set: A = G − W. - -A **code circle** gives the entity a full execution context — a sandbox where it writes and runs arbitrary programs. The medium is code. Variables persist between turns. The action space is the full formula: A = M ∪ G − W. The entity can combine primitives and gates in ways nobody enumerated in advance — loops that call gates conditionally, variables that store results for later turns, data pipelines composed on the fly. This compositionality is what makes code circles the most expressive case — but expressiveness is not the only thing that matters. - -The code medium is not limited to JavaScript sandboxes. Any REPL-like environment can serve: a bash shell, a browser session via CDP, a Frida session. What makes something a medium is that the entity writes instructions in it and the medium executes them. - -``` -MEDIUM-1: A circle MUST have exactly one medium. If no medium is specified, the default is conversation. Public configuration SHOULD use `medium` rather than implementation-specific names (`circle_type`, `backend`, `sandbox_backend`). -``` - -``` -MEDIUM-2: A conformant medium MUST provide four things: gate presentation (presenting gates to the LLM as tool definitions appropriate to the medium), action execution, observation return, and sandbox isolation. The medium enforces the circle's boundary. -``` - -The spec requires sandbox isolation but does not prescribe the technology. QuickJS, Deno, Docker, WASM, restricted Python, Firecracker microVMs — any isolation mechanism that enforces the circle's boundary is valid. - -``` -MEDIUM-3: In a code medium, sandbox state MUST persist across turns within the same entity. A variable set in turn 3 MUST be readable in turn 4. -``` - -``` -MEDIUM-4: Mediums MAY define medium-specific ward types (see WARD-2). -``` - -When a circle has a medium, the medium handles termination internally — the entity calls `submit_answer` in code, and the medium translates this into the done gate mechanism. - -### 4.2 What the entity can do - -The entity's capabilities in a code circle are described by a formula: - -``` -A = M ∪ G − W -``` - -**M** is the medium — builtins, math, strings, control flow, data structures. **G** is the set of registered gates — host functions that cross the boundary into the outside world. **W** is the set of wards — restrictions that constrain the action space. - -When the medium is a programming language, the action space is compositional. The entity can combine primitives and gates in ways nobody enumerated in advance. This compositionality is what separates a code circle from a tool-calling interface. - -``` -CIRCLE-1: A circle MUST provide at least the `done` gate. -``` - -``` -CIRCLE-8: The `done` gate MUST accept at least one argument: the answer/result. When `done` is called, the loop terminates with that result. -``` - -### 4.3 Gates - -Gates are the crossing points through the circle's boundary: how effects reach the outside world, and how outside information reaches the entity. - -Common gates: `done(answer)`, `call_entity(intent, config?)`, `call_entity_batch(intents)`, `read(path)`, `write(path, content)`, `fetch(url)`, `goto(url)` / `click(selector)`. - -Empirical evidence suggests that fewer, well-designed gates often outperform larger gate sets. When the medium is expressive, the entity can compose complex behaviors from a small number of gates. - -Each gate closes over environment state configured at construction time (§7.3). A `read` gate knows its filesystem root. A `fetch` gate carries timeout configuration. The entity calls `read("data.json")` without knowing where the root is. The gate knows. - -``` -CIRCLE-10: Gate dependencies (injected resources) MUST be configured at circle construction time, not at gate invocation time. -``` - -``` -CIRCLE-3: Gate execution MUST be synchronous from the entity's perspective — the entity sends a gate call, the circle executes it, the observation returns before the next turn begins. -``` - -``` -CIRCLE-4: Gate results MUST be returned as observations in the context. The entity MUST be able to see what its gate calls returned. -``` - -``` -CIRCLE-5: If a gate call fails (throws an error), the error MUST be returned as an observation, not swallowed. The entity MUST see its failures. -``` - -Errors are observations. They carry information the entity needs to learn from. Swallowing errors silently cripples the entity — if a file does not exist, the entity needs to see the error so it can try a different path. - -The canonical gate result shape: - -``` -GateCallRecord { - gate_name: string // which gate was invoked - arguments: string // JSON-encoded arguments - result: string // gate output (return value or error message) - is_error: boolean // true if the gate call failed -} -``` - -The observation per turn is an ordered list of `GateCallRecord` objects. A code circle's observation additionally includes sandbox output (stdout, return value, errors). The minimum contract: an observation MUST contain an ordered list of GateCallRecords for every gate invoked during the turn, each with `gate_name`, `arguments`, `result`, and `is_error`. Mediums MAY add additional fields. - -``` -CIRCLE-7: If multiple gate calls appear in a single utterance, the circle MUST execute them in order and return each result as an entry within that turn's single composite observation. The observation is one object per turn (preserving LOOP-1's strict alternation), with an ordered list of per-gate results inside it. Implementations MAY execute independent gate calls in parallel. -``` - -### 4.4 Wards - -Gates open the circle outward. Wards close it back in. They constrain the action space — not permissions granted from nothing, but restrictions carved from the full surface. - -A ward that restricts a gate's reach: "read only from /data." A ward that constrains the medium: "no eval." A ward that caps turns: "max 200 turns." A ward that limits resources: "max 1M tokens." A ward that controls termination: `require_done_tool`. Gate inclusion is a construction concern, not a ward — if you don't want a gate, don't register it. - -``` -CIRCLE-2: A circle MUST have at least one ward that guarantees termination (max turns, timeout, or similar). A cantrip that can run forever is invalid. -``` - -``` -CIRCLE-6: Wards MUST be enforced by the circle, not by the entity. The entity cannot bypass a ward. Wards are environmental constraints. -``` - -A ward is not an instruction the entity might choose to ignore. It is a structural property of the environment. If `fetch` is not registered, the entity cannot make HTTP requests no matter what it writes. If the turn limit is 200, turn 201 does not happen. The entity cannot reason its way around a ward because the ward operates outside the entity's control. - -Start with the fullest possible action space. Then ward off what is dangerous. You do not build up from nothing — you carve down from everything. - -When circles compose — a parent spawning a child via `call_entity` — their wards compose conservatively: the child can never be *less* restricted than its parent. `require_done_tool` uses logical OR: if any ward requires it, it is required. - -``` -WARD-1: When circles compose, numeric wards (max turns, max tokens, max depth) MUST take the `min()` of parent and child values. Boolean wards (`require_done_tool`) MUST take logical `OR` — if either ward requires it, it is required. A child circle's wards can only tighten, never loosen, the parent's constraints. -``` - -``` -WARD-2: Mediums MAY define additional ward types specific to their substrate (e.g., `max_eval_ms` for code circles, compile guards for Elixir circles). Medium-specific wards follow the same composition semantics as WARD-1. -``` - -### 4.5 Tool-calling circles - -Not every circle needs a sandbox. When the LLM uses structured tool calls — JSON function invocations rather than code — the medium is conversation and the action space simplifies to A = G − W. Less expressive than a code circle, but simpler to implement and sufficient for many tasks. - -Implementations MUST support tool-calling circles. Implementations SHOULD support code circles. - -### 4.6 Circle-mediated perception - -The circle does more than execute code. It determines what the entity perceives. - -#### The three message layers - -Every query the circle assembles for the LLM has three layers, in this order: - -1. **Identity**. The system prompt and hyperparameters — who the entity is. Unchanged from construction (IDENTITY-1, IDENTITY-2). - -2. **Capability presentation** (circle-derived). What the LLM can do in this circle — a description of the medium, the registered gates, and their contracts. The circle generates this from its own configuration (CIRCLE-11, IDENTITY-3). It changes when the circle is reconfigured but never during a cast. This separation keeps the identity small and portable — the same identity works in different circles with different gate sets, because the circle presents its own capabilities. - -3. **Intent** (goal). What the entity is pursuing. The first user message, immutable for the cast (INTENT-3). - -Each layer is more specific than the last, and each is owned by a different component: identity owns identity, the circle owns capabilities, the caller owns intent. - -``` -CIRCLE-11: The circle MUST generate a capability presentation for the LLM — a description of the medium, registered gates, and their contracts. This presentation MUST be included in the LLM's context on every query, between the identity and the intent. Gate definitions in the `tools` parameter and capability documentation in the prompt are both valid forms of this presentation. -``` - -#### Gate presentation - -Gate presentation is medium-specific. In a tool-calling circle, each gate appears as a separate tool definition; `tool_choice` defaults to `"auto"`. In a code circle, the LLM sees a single tool — the medium's code execution interface (e.g., `js`); `tool_choice` is `"required"`. Gates are projected into the medium as host functions — the medium decides how they appear. - -``` -// Tool-calling circle: tools = [read, write, fetch, done], tool_choice = "auto" -// Code circle: tools = [js], tool_choice = "required" -// Gates appear as: read(), write(), fetch(), submit_answer() inside the sandbox -``` - -The LLM does not know it is calling gates — it writes code that calls functions. The medium bridges between the LLM's perception and the circle's reality. - -#### The medium viewport principle - -A medium SHOULD present execution results as metadata — size, type, a short preview — rather than raw output. As the prompt fills with raw data, the LLM's ability to attend to relevant information diminishes (context rot). When the medium returns a summary — `[Result: 4823 chars] "first 150 chars..."` — the entity must compose operations to work with the data through code. The viewport forces compositional behavior. - -### 4.7 Circle state - -The circle maintains state between turns in two forms. - -**Sandbox state** — variables, data structures, intermediate results inside the execution context. Private to the entity; dies when the entity terminates. This is MEDIUM-3. - -**External state** — filesystem, database, browser DOM, whatever gates can reach. May be shared across entities or persist beyond an entity's lifetime. - -### 4.8 Security - -Security in the circle model is a question of warding. The canonical threat is the lethal trifecta: a circle that has access to private data, processes untrusted content, and can communicate externally. Any two are manageable. All three create a path for data exfiltration. - -The defense is subtractive. Remove one leg by warding off the relevant gate. A circle that processes untrusted content and reads private data but cannot make network requests is safe against exfiltration. Alternatively, isolate capabilities across separate circles. - -**Prompt injection** is the specific threat that makes careful circle design non-optional. Untrusted content may contain instructions that attempt to override the identity. The entity cannot reliably distinguish between its own instructions and adversarial text embedded in its input. This is a structural property of systems that process natural language: the control channel and the data channel are the same channel. - -Wards cannot prevent the entity from being influenced by its input — they can only prevent the entity's actions from reaching dangerous gates. The defense is circle design: isolate the processing of untrusted content from circles that have access to sensitive data or external communication. - -Wards must be structural, not advisory. The entity has read every attack and every defense in its training data. Containment cannot rely on the entity choosing to respect boundaries — politeness is trained behavior, not a reliable property. Wards are environmental constraints because the entity cannot be trusted to self-limit. - ---- - -## Chapter 5: Composition - -So far, every entity has been alone. Some tasks are too large for one entity, or too naturally decomposable, or too parallelizable. The entity needs to delegate. - -In a code circle, delegation is a function call. The entity writes `call_entity({ intent: "summarize this document" })` and a child entity appears in its own circle, pursues that sub-intent, and returns a result. Composition through gates is composition through code, which means the entity can invent delegation patterns its designers never enumerated. - -### 5.1 The `call_entity` gate - -``` -result = call_entity({ - intent: string, // what the child should pursue - context?: string, // additional context injected into child's circle - gates?: string[], // which gates the child's circle registers - wards?: Ward[], // child-specific wards (composed with parent's via WARD-1) - llm?: string, // which LLM the child uses - identity?: Identity, // the child's identity (system prompt, hyperparameters) - medium?: string // the child's medium (e.g., "code", "conversation") -}) -``` - -The entity proposes the child's configuration. Fields beyond `intent` are optional — defaults are typically inherited from the parent or from construction-time configuration. Behind the scenes, a **spawn function** (`SpawnFn`) receives the proposal and handles circle construction, ward composition, depth decrement, and loom sharing. The spawn function validates and may modify the proposal — enforcing ward tightening (WARD-1) or rejecting gate sets that violate security policy. - -The child entity gets its own circle, its own context, its own turn sequence. It does not inherit the parent's conversation history — it starts fresh, with only the sub-intent and whatever data the parent passes through `context`. - -``` -COMP-4: A child entity MUST have its own independent context (message history). The child does not inherit the parent's conversation history. -``` - -``` -COMP-1: A child entity's circle is independently constructed. The parent MAY constrain the child via ward composition, but the child's gate set, medium, and LLM are not required to be derived from the parent. -``` - -``` -COMP-7: The child's LLM MAY differ from the parent's LLM. The child's identity MAY differ. The child's circle MAY differ — including different gates, a different medium, or different wards. Ward composition (WARD-1) still applies to any wards the parent imposes. -``` - -If the caller does not specify a child identity, the child gets a generic prompt oriented toward task completion — not the parent's identity. The child is a worker, not a clone. - -``` -COMP-10: If no identity is provided for a child entity, the implementation MUST supply a generic child identity (e.g., "You are a child entity. Pursue the intent and return the result."). The child MUST NOT inherit the parent's system prompt by default. -``` - -``` -COMP-11: The spawn function MUST strip `call_entity` and `call_entity_batch` from the child's gate set when the child's composed `max_depth` is 0 (see COMP-6). The child's circle is constructed without delegation gates — the child cannot attempt to delegate. -``` - -The parent blocks while the child runs — the same synchronous contract as any other gate (CIRCLE-3). The child entity lives its entire life within the parent's turn. - -``` -COMP-2: `call_entity` MUST block the parent entity until the child completes. The parent receives the child's result as a return value. -``` - -``` -COMP-8: If a child entity fails (throws an error, not `done`), the error MUST be returned to the parent as the gate result. The parent MUST NOT be terminated by a child's failure. -``` - -``` -COMP-9: When a parent entity is terminated or truncated, active child entities SHOULD be truncated with reason `parent_terminated`. Child turns up to the cancellation point are preserved in the loom. The child's truncation is recorded as any other truncation — the loom distinguishes it only by the reason field. -``` - -### 5.2 Batch composition - -`call_entity_batch` spawns multiple children in parallel: - -``` -results = call_entity_batch([ - { intent: "Summarize chunk 1", context: chunk1 }, - { intent: "Summarize chunk 2", context: chunk2 }, - { intent: "Summarize chunk 3", context: chunk3 }, -]) -``` - -Results are returned in request order, not completion order. - -``` -COMP-3: `call_entity_batch` MUST execute children concurrently. Results MUST be returned in request order, not completion order. Implementations SHOULD enforce concurrency limits (default: 8 concurrent children, 50 maximum batch size) to prevent resource exhaustion. -``` - -### 5.3 Composition as code - -The entity calls `call_entity` inside loops, behind conditionals, as part of data pipelines it writes on the fly: - -``` -const chunks = splitIntoChunks(context.documents, 100); -const summaries = call_entity_batch( - chunks.map(chunk => ({ - intent: "Extract key findings", - context: { documents: chunk } - })) -); -done(summaries.join("\n")); -``` - -The number of children is determined at runtime by the data, not at design time by the developer. This is what separates composition-through-code from a static workflow graph. - -### 5.4 Depth limits - -Composition is recursive — a child entity has the `call_entity` gate in its circle, so it can spawn children of its own. Every cantrip has a `max_depth` ward to prevent infinite recursion. - -- Depth 0 means no `call_entity` allowed — the gate is warded off -- Each child's depth limit is the parent's depth minus 1 -- Default depth is 1 (the entity can spawn children, but those children cannot spawn their own) - -``` -COMP-6: When `max_depth` reaches 0, the `call_entity` and `call_entity_batch` gates MUST be removed from the circle (warded off). Attempts to call them MUST fail with a clear error. -``` - -### 5.5 Composition in the loom - -Every child entity's turns are recorded in the same loom as the parent. The child's turns form a subtree rooted at the parent turn that spawned it. - -``` -Parent turn 1 -Parent turn 2 (calls call_entity) -├── Child turn 1 -├── Child turn 2 -└── Child turn 3 (done) -Parent turn 3 (receives child result) -``` - -``` -COMP-5: A child entity's turns MUST be recorded in the loom as a subtree. The child's root turn references the parent turn that spawned it. -``` - ---- - -## Chapter 6: The Loom - -Every chapter so far has produced turns. The loop runs, the entity acts, the circle responds, turn after turn. Then the loop ends and the entity is gone. - -Where did the turns go? - -They went into the loom. Every turn — every utterance, every observation, every gate call — was being recorded as it happened, appended to a growing tree. One path through that tree is a thread. All threads, across all runs of a cantrip, form the loom. The entity is transient; the loom is durable. - -The loom was accumulating from the first turn of Chapter 1. When composition spawned child entities in Chapter 5, their turns went into the same loom. The structure described in every prior chapter — the loop, the observations, the parent-child relationships — is the structure of the loom. - -### 6.1 Turns as nodes - -Each turn is stored as a record: - -``` -Turn { - id: string // unique identifier - parent_id: string? // null for root turns - cantrip_id: string // which cantrip produced this turn - entity_id: string // which entity was acting - role: string // "identity" | "turn" - sequence: number // position within this entity's run (1, 2, 3...) - - utterance: string // what the entity said/wrote - observation: string // what the circle returned - - gate_calls: GateCall[] // structured record of which gates were invoked - - metadata: { - tokens_prompt: number - tokens_completion: number - tokens_cached: number - duration_ms: number - timestamp: ISO8601 - } - - reward: number? // reward signal, if assigned - terminated: boolean // did this turn end with `done`? - truncated: boolean // did a ward cut the entity off here? -} -``` - -``` -LOOM-1: Every turn MUST be recorded in the loom before the next turn begins. Turns are never lost. -``` - -``` -LOOM-2: Each turn MUST have a unique ID and a reference to its parent (null for root turns). -``` - -``` -LOOM-9: Each turn MUST record token usage (prompt, completion, cached) and wall-clock duration. -``` - -### 6.2 Threads - -Turns link to their parents. Follow those links from any leaf to the root and you have a thread — one complete path through the turn tree. Threads are implicit — they emerge from parent references. You store turns with parent pointers; a thread is any root-to-leaf path. - -A thread has exactly one terminal state: **terminated** (`done` called), **truncated** (ward stopped it), or **active** (still running). - -``` -LOOM-7: The loom MUST record whether each terminal turn was terminated (entity called `done`) or truncated (ward stopped the entity). -``` - -This distinction is load-bearing for training. Terminated threads have natural endpoints. Truncated threads do not. - -### 6.3 The loom - -The loom is the tree of all turns produced by a cantrip across all runs. Cast ten intents: ten threads. Fork from turn seven: two threads sharing a prefix. Compose with `call_entity`: child subtrees inside parent threads. - -This is simultaneously the debugging trace, the entity's memory, the training data, and the proof of work. - -### 6.4 Reward and training data - -Each turn is a (context, action, observation) triple. Each thread is a trajectory. The reward slots are already there. - -The loom stores a reward slot on every turn: - -- **Implicit reward** — gate success/failure as a natural per-turn signal. -- **Explicit reward** — a score attached after the fact by a human, a verifier, or a verifier entity. -- **Shaped reward** — intermediate rewards from a scoring function that is part of the circle definition. - -Modern LLM-RL methods — GRPO, RLAIF, best-of-N — learn by comparing multiple trajectories of the same task. Fork from the same turn N times, or cast the same intent N times, and you get N threads to rank. The ranking is the reward signal — no reward model needed. The loom's tree structure provides exactly the trajectory data comparative RL methods need. - -``` -// Same intent, three runs: -// -// Thread A: 12 turns, fixed the bug, clean solution -> rank 1 -// Thread B: 18 turns, fixed the bug, messy refactor -> rank 2 -// Thread C: 25 turns, truncated by ward, bug not fixed -> rank 3 -// -// The ranking IS the reward signal. -``` - -Two metrics apply directly: **pass@k** (at least one of k threads succeeds) and **pass^k** (all k succeed). Both are computable from threads sharing a common intent. - -(Multi-turn credit assignment remains an active research problem. The loom provides the trajectory structure these methods need; credit assignment and reward propagation are the responsibility of whatever training infrastructure consumes it.) - -``` -LOOM-10: The loom MUST support extracting any root-to-leaf path as a thread (trajectory) for export, replay, or training. -``` - -### 6.5 Storage - -Turns are appended as they happen. The loom is append-only. The reference format is JSONL. - -``` -LOOM-3: The loom MUST be append-only. Turns MUST NOT be deleted or modified after creation. Reward annotation is the exception — reward MAY be assigned or updated after creation. -``` - -### 6.6 Forking - -Forking creates a new turn whose parent is an earlier turn in the tree, diverging from the original continuation. - -``` -// Original thread: turns 1 -> 2 -> 3 -> 4 -> 5 -// Fork from turn 3: -// turns 1 -> 2 -> 3 -> 4 -> 5 (original thread) -// \-> 6 -> 7 (forked thread) -``` - -A forked entity starts with the context from root to the fork point. The original thread is untouched. - -``` -LOOM-4: Forking from turn N MUST produce a new entity whose initial context is the path from root to turn N. The original thread MUST be unaffected. -``` - -Implementations MUST declare how sandbox state is captured at fork points. **Snapshot** serializes current state into a portable image. **Replay** re-executes the entity's code from root to the fork point. Both produce the same logical state; they differ in cost and fidelity. Snapshot is fast but may struggle with imperative state that resists serialization. Replay is slow but faithful. The loom MUST record which strategy was used. - -``` -LOOM-13: When using replay-based forking, gate results MUST be hydrated from the loom's recorded observations rather than re-executed. Gates are not called during replay — their recorded results are injected into the sandbox as if the gates had run. This prevents non-idempotent side effects from being duplicated. -``` - -Forking is not an environment reset. The forked entity continues from accumulated state at the fork point. - -### 6.7 Composition in the loom - -When `call_entity` spawns a child, the child's turns form a subtree — the same mechanism as forking. Everything stays in one tree. - -``` -LOOM-8: Child entity turns from `call_entity` SHOULD be stored in the same loom as the parent, with parent references linking them to the spawning turn. Implementations that store child turns in a separate loom MUST still record the parent-child relationship. -``` - -``` -LOOM-12: The loom SHOULD be a single unified tree. When all entities — parent, child, grandchild — record their turns into the same tree, a thread is any root-to-leaf path, and the tree's branching structure encodes the full delegation hierarchy. -``` - -### 6.8 Folding and compaction - -Context grows. Eventually the accumulated context approaches the LLM's window limit. - -**Folding** is the deliberate integration of loom history into circle state. Instead of keeping every prior turn in the message list, the circle takes the substance of earlier turns and encodes it as state the entity can access through code: variables, data structures, summaries in the sandbox. The full turns remain in the loom. The entity's working context shrinks because the knowledge now lives in the environment — context belongs in the environment, not in the prompt (§3.3). - -``` -LOOM-5: Folding MUST NOT destroy history. The full turns MUST remain accessible. Folding produces a view, not a mutation. -``` - -``` -LOOM-6: Folding MUST NOT compress the identity or the circle's gate definitions. The system prompt, hyperparameters, and gate definitions MUST always be present in the entity's context. -``` - -**Compaction** is the fallback. When folding is insufficient, compaction truncates or summarizes the oldest turns in the prompt — a sliding window or a compressed digest. The entity loses detailed access, but the loom retains everything underneath. - -``` -// Folding: [identity] [intent] [recent turns] -// Circle state holds synthesized knowledge from earlier turns - -// Compaction: [identity] [intent] [summary of turns 1-20] [turns 21-30] - -// Loom: all turns intact in both cases -``` - -**Who triggers folding.** The circle or harness, automatically (PROD-4). The entity does not usually decide when to fold. - -**Trigger threshold.** Folding MAY trigger when context exceeds 80% of the LLM's advertised window. Implementations MAY use a different threshold but MUST document it. - -**What form.** Folding replaces a range of turns with a summary node in the working context. In a code circle, folding MAY also encode state as sandbox variables. - -**Fidelity.** The entity MUST be able to distinguish folded context from unfolded. A folded summary MUST be explicitly marked — e.g., `[Folded: turns 1-20]`. The entity should never mistake a summary for a verbatim record. - -**Implementation freedom.** The spec defines what folding must preserve (LOOM-5, LOOM-6), when it should trigger (PROD-4), and what the entity must be able to tell (fidelity marking). It does not prescribe how summaries are generated — a dedicated LLM call, a templated extractor, a medium-specific state serializer, or something not yet invented. The mechanism depends on the medium, the model, and the use case. - -``` -// Before: [identity] [intent] [turn 1] ... [turn 24] [turn 25] ~102k tokens -// After: [identity] [intent] [folded: turns 1-18] [turn 19] ... [turn 25] ~45k tokens -``` - -### 6.9 The loom as entity-readable state - -The loom can also face inward. A circle MAY expose the loom as a readable object in the entity's sandbox. When it does, the entity can access its own history through code — summarizing old turns, comparing approaches, inspecting sibling threads. - -When the entity manages its own context through code, that intelligence compounds through training. When the harness manages context through built-in logic, that intelligence helps now but does not train into the next generation. - -``` -LOOM-11: The loom MAY be exposed as a readable object within the circle's sandbox. When exposed, the entity accesses its own history through code execution, not through special observation channels. -``` - ---- - -## Chapter 7: Production - -An entity that works in a demo and an entity that works in production are separated by problems that are boring to describe and fatal to ignore. None of this changes the vocabulary — every concept from the previous chapters applies unchanged. What changes is the operational discipline. - -### 7.1 Context management in production - -For context management strategies including folding and compaction, see §6.8. - -``` -PROD-4: Folding MUST be triggered automatically when context approaches the LLM's limit. Implementations MAY trigger folding when context exceeds 80% of the LLM's advertised window (see §6.8). Implementations that use a different threshold MUST document it. -``` - -### 7.2 Ephemeral gates - -Some gate results are large and useful for exactly one turn. An ephemeral gate's observation is replaced with a compact reference after the entity's next turn. The full content is stored in the loom — the observation is never lost — but it is removed from the working context. If the entity needs the content again, it calls the gate again. - -``` -PROD-5: If ephemeral gates are supported, the full observation MUST still be stored in the loom. Only the working context is trimmed. -``` - -### 7.3 Dependency injection - -Gates close over environment state. A `read` gate knows its filesystem root. A `call_entity` gate holds a reference to the LLM for child entities. A `fetch` gate carries timeout configuration. These dependencies are injected when the circle is constructed, not when the entity invokes the gate (CIRCLE-10). - -``` -circle = Circle({ - gates: [ - read.with({ root: "/data" }), - fetch.with({ timeout: 5000 }), - call_entity.with({ llm: child_llm, max_depth: 2 }) - ], - wards: [max_turns(100)] -}) -``` - -Two kinds of configuration: **gate dependencies** (filesystem roots, auth headers, timeouts) are construction-time concerns. **Circle configuration** (which gates, which medium, which LLM) is what the entity proposes at call time via `call_entity` (§5.1). The spawn function bridges these: it receives the entity's circle configuration proposal and wires up the gate dependencies. - -### 7.4 Infrastructure rules - -``` -PROD-1: Protocol adapters MUST NOT alter the entity's behavior. The same cantrip MUST produce the same behavior regardless of whether it is accessed via CLI, HTTP, or ACP. -``` - -ACP (Agent Communication Protocol) maps sessions to summoned entities and messages to casts. HTTP, WebSocket, stdio, gRPC — all valid transports. The spec defines the behavioral contract, not the wire format. - -``` -PROD-2: Retry logic MUST be transparent to the entity. A retried LLM query MUST appear as a single turn, not multiple turns. Implementations SHOULD retry rate limits (429) and server errors (5xx) with exponential backoff starting at 1 second, up to a configurable maximum (default: 3 retries). Client errors (4xx except 429) MUST NOT be retried. -``` - -``` -PROD-3: Token usage MUST be tracked per-turn and cumulatively per-entity. -``` - -``` -PROD-6: Implementations that expose ACP MUST support the core session flow (`initialize`, `session/new`, `session/prompt`) and emit session update notifications in ACP-compatible shape. Prompt payload parsing SHOULD accept common client variants (`prompt`, `content`, text blocks) as long as intent text can be extracted unambiguously. -``` - -``` -PROD-7: Protocol sessions (ACP, HTTP session APIs, or equivalent) MUST preserve per-session conversational continuity unless explicitly configured as stateless. A follow-up prompt in the same session MUST execute with prior session context available. -``` - -``` -PROD-8: Implementations MUST redact secrets from logs, traces, and default loom exports. Credentials and tokens MAY be stored only in explicitly configured secure stores and MUST NOT appear in user-visible observations by default. -``` - -``` -PROD-9: Interactive stdio adapters (including ACP stdio servers) SHOULD document lifecycle semantics clearly: idle waiting for requests is healthy behavior, and a health-check command or debug mode SHOULD be provided for protocol troubleshooting. -``` - -### 7.5 Streaming events - -Implementations SHOULD emit streaming events as they occur. Streaming is an observation channel, not a control channel — events report what the loop is doing but do not affect execution. - -The event hierarchy follows the loop structure: - -- **TextEvent** / **ThinkingEvent** — content chunks from the LLM -- **ToolCallEvent** / **ToolResultEvent** — gate invocation and result -- **FinalResponseEvent** — the done gate's result -- **MessageStartEvent** / **MessageCompleteEvent** — LLM response boundaries -- **StepStartEvent** / **StepCompleteEvent** — turn boundaries -- **UsageEvent** — token counts for a query - ---- - -## Glossary - -Every term in this document was defined in context as it appeared. This table is for quick reference when you need to look one up. - -| # | Term | Common alias | Definition | -|---|------|-------------|-----------| -| 1 | **LLM** | model, crystal | The model. Stateless: messages in, response out. | -| 2 | **Identity** | config, call, conditioning | Immutable identity: system prompt + hyperparameters. What the LLM *is*. | -| 3 | **Gate** | tool, function | Host function that crosses the circle's boundary. | -| 4 | **Ward** | constraint, restriction | Subtractive restriction on the action space. | -| 5 | **Circle** | environment, sandbox | The environment: medium + gates + wards. The medium is the substrate the entity works *in*. | -| 6 | **Intent** | task, goal | The goal. What the entity is trying to achieve. | -| 7 | **Cantrip** | agent config | The script: LLM + identity + circle. A value, not a process. | -| 8 | **Entity** | agent instance | What emerges when you summon a cantrip. The living instance. Persists across turns when summoned; discarded after one run when cast. | -| 9 | **Turn** | step | One cycle: entity acts, circle responds, state accumulates. | -| 10 | **Thread** | trajectory, trace | One root-to-leaf path through the loom. A trajectory. | -| 11 | **Loom** | execution tree, replay buffer | The tree of all turns across all runs. Append-only. | -| 12 | **Medium** | substrate, environment type | The substrate the entity works *in*. The inside of the circle. Conversation, code sandbox, browser, shell. | - -These terms have an internal structure. Three are primaries: LLM, identity, circle. One is emergent: the entity, which appears when the three primaries are bound in a loop. The rest pair naturally: gate and ward, intent and thread, turn and loom. The cantrip is the whole that contains all of them. The medium is the circle's interior. - -## Conformance - -This spec is the durable artifact. Tests should be generated from the spec. Code generated from the tests. This is the **ghost library pattern**: the specification is a library with no implementation code — everything else is ephemeral and can be regenerated. The spec defines behavior; implementations are disposable manifestations of that behavior. When the spec changes, tests and code follow. When code drifts from the spec, the code is wrong. - -An implementation is conformant if it satisfies three conditions: - -1. It implements all terms as described -2. It passes the test suite (`tests.yaml`) -3. Every behavioral rule (LOOP-*, CANTRIP-*, INTENT-*, ENTITY-*, LLM-*, IDENTITY-*, CIRCLE-*, MEDIUM-*, WARD-*, COMP-*, LOOM-*, PROD-*) is satisfied - -Implementations MAY extend the spec with additional features as long as the core behavioral rules are preserved. The vocabulary is fixed. What you build on top of it is yours. - -The canonical implementation is Elixir/OTP. Earlier TypeScript, Python, -and Clojure realizations were useful learning and reference artifacts; -the spec remains the source of truth. - -## Appendix A: Grimoire - -A grimoire is a book of spells. The preceding chapters defined the vocabulary. This appendix shows what you build with those words. Each pattern adds one idea to the previous, expanding what is possible. The arc is not a hierarchy: a conversation circle with no code medium is complete, and so is a familiar that orchestrates a fleet of child entities. - -A conformant implementation SHOULD provide runnable examples for each pattern below. - ---- - -### A.1 Query - -One round-trip. No loop, no circle, no entity — just the atomic unit (§2.1). - -``` -llm = create_llm(model) -response = llm.query([{ role: "user", content: "What is 2 + 2?" }]) -``` - -**What to notice.** The response contains content, token usage, and nothing else. No state was created. The LLM is exactly as it was before the call (LLM-1). - -**Substitution.** Any model from any provider. The contract is the same. - ---- - -### A.2 Gate - -Define a gate, execute it directly. A gate is a host function with metadata — a crossing point through the circle's boundary (§4.3). - -``` -gate add(a, b) -> a + b -gate done(answer) -> terminates loop -``` - -**What to notice.** Gates can be tested in isolation. If the host function throws, that throw becomes observation data (CIRCLE-5). The `done` gate is special — every circle must have one (CIRCLE-1). Gates close over environment state configured at construction time (CIRCLE-10). - -**Substitution.** Any function can be a gate. The entity only sees the schema. - ---- - -### A.3 Circle - -Gates and wards assembled into an environment (§4.1). - -``` -circle = Circle( - gates: [greet, done], - wards: [max_turns(10)] -) -``` - -**What to notice.** The errors. A circle without `done` is rejected at construction (CIRCLE-1). A circle without a termination ward is rejected (CIRCLE-2). The circle prevents misbehavior from being possible, rather than waiting for it to happen. - -**Substitution.** Any gate set. Any ward set. The structural invariants are the same. - ---- - -### A.4 Cantrip - -LLM, identity, and circle bound into a reusable value (§1.4). - -``` -spell = cantrip(llm, identity, circle) -result_1 = spell.cast("What is 2 + 3?") -result_2 = spell.cast("What is 10 + 20?") -``` - -**What to notice.** Two casts produce independent entities (CANTRIP-2). The identity is fixed (IDENTITY-1). The intent varies (INTENT-1). You didn't design the entity — you designed its components. - -**Substitution.** Any LLM. Any identity. Any circle. The cantrip is the composition. - ---- - -### A.5 Wards - -Wards are subtractive — they carve away from the full action space (§4.4). - -``` -wards = compose([max_turns(50), max_turns(10), max_turns(100)]) -// resolved: max_turns = 10 (min wins) - -wards = compose([require_done_tool(true), require_done_tool(false)]) -// resolved: require_done_tool = true (OR wins) -``` - -Stack three `max_turns` wards — 50, 10, 100 — and the resolved value is 10 (min). `require_done_tool` composes with OR (WARD-1). When depth reaches zero, delegation gates disappear entirely (COMP-6). The entity is not asked to avoid recursion — recursion is structurally unavailable. - -**What to notice.** Wards provide safety through architecture, not politeness. An entity cannot be persuaded to ignore a ward because the ward operates outside the entity's context (CIRCLE-6). - -**Substitution.** Adjust ward values to your risk tolerance. The composition semantics are fixed. - ---- - -### A.6 Medium - -Change the medium from conversation to code. Same gates, radically different action space (§4.1). - -``` -circle = Circle( - medium: code("language"), - gates: [read, done], - wards: [max_turns(20)] -) -``` - -**What to notice.** A = M ∪ G − W becomes concrete. In conversation, A collapses to G − W. In code, M is a full programming language. Data injected into the sandbox is accessible as a variable — the entity explores it through code rather than holding it in the prompt. Context belongs in the environment (§3.3). Variables persist across turns (MEDIUM-3). - -**Substitution.** JavaScript, Python, Bash, browser — any REPL-like environment. The medium determines what the entity works *in*. - ---- - -### A.7 Codex - -A code medium with real gates — filesystem access, shell commands, network requests. Error as steering: the entity hits an error and adapts (§4.3, CIRCLE-5). - -``` -spell = cantrip(llm, identity, Circle( - medium: code("javascript"), - gates: [read, write, list_dir, done], - wards: [max_turns(20)] -)) -result = spell.cast("Find all TODO comments in /src and write a summary to /out/todos.md") -``` - -**What to notice.** After several turns, the entity's output looks nothing like its first turn. It references variables from earlier, works around errors it hit, pursues emergent strategies. Robustness comes from visibility of failure, not absence of failure. - -**Substitution.** Any gate set that touches the real world. The loop handles errors the same way regardless of what went wrong. - ---- - -### A.8 Folding - -Long-running entities trigger folding (§6.8). Old turns compressed, recent turns preserved. The loom retains full history. - -``` -before: [identity][intent][turn 1..24][turn 25] -after: [identity][intent][folded 1..18][turn 19..25] -loom: full turns 1..25 still present -``` - -**What to notice.** Folding changes what is in immediate view, not what exists (LOOM-5). The identity and gate definitions are never folded (LOOM-6). In a code circle, sandbox state persists even after turns are folded — knowledge lives in the environment as program state. - -**Substitution.** Any folding strategy — LLM-generated summaries, templated extractors, state serializers. The invariants (LOOM-5, LOOM-6) are the same. - ---- - -### A.9 Composition - -The entity delegates via `call_entity` (§5). In a code circle, delegation is a function call inside loops, behind conditionals, as part of pipelines composed on the fly. - -``` -parts = split(task) -results = call_entity_batch(parts.map(p => { intent: p })) -final = merge(results) -``` - -**What to notice.** The loom captures parent and child turns in the same tree. Walk the parent's thread and delegation appears as one step. Walk into the child's subtree and every decision is visible. Children run concurrently, results return in request order (COMP-3). The child's circle is independent (COMP-4). Depth limits prevent infinite recursion (COMP-6). - -**Substitution.** Different LLMs for children. Different mediums. Different gate sets. Ward composition ensures children can only be more restricted (WARD-1). - ---- - -### A.10 Loom - -Inspect the loom after a run (§6). Every turn since the first pattern has been recorded — the loom is append-only (LOOM-3). - -**What to notice.** Threads are implicit — follow parent pointers from leaf to root. The loom records terminated vs. truncated (LOOM-7). Fork from a turn: two threads sharing a prefix, diverging. The tree structure is shaped for comparative RL: fork N times, rank, learn. No reward model needed — comparison is the signal (§6.4). - -**Substitution.** JSONL, SQLite, any append-only store. The tree semantics are the same. - ---- - -### A.11 Persistence - -Summoning creates an entity that survives its first intent (ENTITY-5). - -``` -entity = spell.summon() -entity.send("Set up the project structure") -entity.send("Now add the test suite") -``` - -**What to notice.** The second intent benefits from everything the first produced. Variables persist. Files written during the first send are readable during the second. The identity hasn't changed — who the entity is remains fixed. The entity builds on accumulated state, not from scratch. - -**Substitution.** Any cantrip can be summoned. Casting is summoning with automatic cleanup. - ---- - -### A.12 Familiar - -A persistent entity that constructs and orchestrates other cantrips through code. The familiar observes a codebase through read-only gates, reasons in a code medium, and delegates action to child cantrips that it constructs at runtime — choosing their LLM, medium, gates, and wards based on what the task requires. - -The familiar's action space includes cantrip construction — the ability to design new circles, choose new LLMs, and compose capabilities that its own circle does not directly contain. It delegates through code, which means it can invent delegation patterns nobody enumerated in advance: recursive analysis, parallel fan-out, conditional routing, retry loops that spawn fresh entities on failure. - -The loom is persisted to disk. When the familiar is summoned again in a new session, it loads its prior history and continues with accumulated context. Combined with folding, this gives the familiar long-term memory bounded only by storage. - -**What to notice.** The familiar itself has few gates — observation and cantrip construction. The children do the work. The familiar decides what work needs doing.

The LLM, the identity, the circle, the gates, the wards — each constructed where you can see it, not hidden behind a helper function. - -A teaching example maps code to concepts. Comments anchor what is happening to the spec's vocabulary: this is the identity, this is the circle's gate set, this is the ward that guarantees termination. - -A teaching example shows the non-happy path. The circle rejects construction without a `done` gate. A ward truncates the entity. A gate returns an error and the entity adapts. - -A teaching example uses realistic intents. "Say ok" proves the API works. "Analyze each category and summarize the overall trend" shows what the entity actually does across multiple turns. - -A teaching example inspects its output. Print the result, but also print how many turns the loom recorded, whether the thread terminated or was truncated, what gates were called. - -The difference between conformance theater and a teaching example is the difference between proving something works and showing someone how it works.

It is the canonical package implementation of the Cantrip +spellbook lineage: the original ghost-library vocabulary is preserved, while +the runtime surface is ordinary Elixir. + +## Core Shape + +A cantrip is a reusable value. It combines: + +- an LLM behaviour implementation and provider state +- an identity with system prompt and model-facing options +- a circle describing medium, gates, and wards +- optional loom storage, retry, and folding configuration + +Casting a cantrip starts a one-shot entity. Summoning a cantrip starts a +supervised entity process that can receive multiple intents. The entity is what +emerges from the loop; the cantrip is the configuration that produces it. + +The circle is the runtime contract: + +```text +A = M union G - W +``` + +The medium determines the shape of thought. Gates expose host capabilities. +Wards bound runtime behavior. The loom is the durable tree left behind by the +entity's turns. The Familiar's default code medium runs Dune-restricted Elixir +in a child BEAM, with gates and child cantrip API calls resolved by the parent +runtime. + +## Runtime Loop + +`Cantrip.cast/3` starts a supervised `Cantrip.EntityServer` for one episode. +`Cantrip.summon/1` starts a persistent entity; `Cantrip.summon/2` starts one +and immediately runs its first intent. `Cantrip.send/3` continues it. + +Each turn: + +1. folds prompt context if configured +2. presents the selected medium to the LLM +3. invokes the provider through `Cantrip.ProviderCall` +4. classifies the response in `Cantrip.Turn` +5. executes through the medium +6. appends the utterance and observations to the loom +7. either terminates, truncates, or continues + +Errors that belong to the entity's operating environment are observations. +They are returned to the loop as data instead of crashing the process. + +## Mediums + +`Cantrip.Medium.Conversation` projects gates as provider tool definitions. + +`Cantrip.Medium.Code` evaluates Elixir with persistent bindings. By default, +it evaluates Dune-restricted Elixir in a child BEAM process, equivalent to +`sandbox: :port`. Add `%{port_runner: [...]}` to put that child under +deployment-level OS/container controls. `sandbox: :port_unrestricted` keeps +the child process but evaluates raw Elixir there. `sandbox: :dune` routes +through the in-process Dune evaluator. `sandbox: :unrestricted` uses the old +host-BEAM evaluator for trusted local development. + +`Cantrip.Medium.Bash` executes one shell command per turn. Shell process state +does not persist; filesystem effects do. + +## Composition + +Composition uses the public package API, not special delegation gates. +Code-medium entities call `Cantrip.new/1`, `Cantrip.cast/3`, and +`Cantrip.cast_batch/2` directly. Parent context supplies inherited child LLM, +wards, root dependencies, cancellation, streaming, and loom grafting. + +This is the RLM pattern in package form: large context lives in the medium, +subtasks run as child cantrips, and summaries return upward. Composition is +code, not a static workflow graph. + +## Loom + +The loom is the durable artifact of the loop. It records intents, turns, +utterances, observations, child turns, metadata, and fork lineage. + +Backends: + +- memory for ephemeral tests and scratch sessions +- JSONL for portable traces +- Mnesia for BEAM-native durable workspace state + +Folding is a view over prompt context. When the message history grows past +a configured threshold, older turns are summarized into a compact `[Folded: +turns N..M]` marker in the LLM's input. The original turns remain in the +loom unchanged — folding shrinks what the model sees on the next call, not +what was recorded.

Your medium is Elixir. + Your gates let you observe the workspace. Your wards bound your action + space. Your loom is the durable tree of what you and your children did. - ## The grain of this medium - - - Your turn code is top-level scripts — no `defmodule` in a turn's - utterance (that's what `compile_and_load` is for). Use anonymous - functions (`fn v -> ... end`) for in-turn helpers. - - Heredocs need their own opening line — never directly after an `=`. - Prefer single-line strings unless you genuinely need multi-line. - - `list_dir` returns a list of strings; `search` returns a list of - maps. Use `Enum.*` on them directly. - - Pipe into `then(fn v -> ... end)`, not into `(fn v -> ... end).()`. - - Each `Cantrip.cast` is an LLM round-trip. For more than a couple, use - `Cantrip.cast_batch` so they run in parallel.

Pre-#20, list_dir was "effectively unscoped" and tolerated missing root. Post-#20 (Cantrip.Gate.Path.validate/2 fail-closed on missing root), list_dir correctly errors, which made every iteration in the live test fail at the gate call. The cleanup work was correct; the live test wasn't updated to match the tightened security contract. Fix: pass `dependencies: %{root: File.cwd!()}` to the list_dir gate.

The gate asserts that patterns the cleanup pass eliminated (unbounded String.to_atom, binary_to_term without [:safe], Code.eval_string, ambient System.get_env in hot paths, bare spawn) have not been reintroduced. New occurrences outside an explicit per-file allowlist fail CI. The allowlist is documented inline in the script with the reason each file is exempted (e.g. compile_and_load.ex String.to_atom is bounded by upstream allowlist check; port_child.ex Code.eval_quoted runs in the sandboxed child BEAM). New patterns require either fixing the violation or adding the file with a justifying comment. Closes the lock-in half of Pass 15 — the codebase can no longer silently regress to the patterns the cleanup just removed.

Surfaced one bug, fixed it: - -**Bug:** `EntityServer.execute_turn/4` only updated `state.messages` via `Cantrip.Turn.next_messages/3` on the *non-terminating* branch. On termination it returned the final response without folding the terminating assistant message back into `state.messages`. - -**Effect:** the next `send` appended a user message to a history that still ended at the *prior* user message. After three sends the model saw `[sys, sys, user_1, user_2, user_3]` with no record of its own answers and anchored on user_1 — every prompt returned the first answer. - -**Why it shipped:** the existing `Cantrip.SummonTest` multi-send case used `FakeLLM` with deterministic per-call responses that don't use context, so the test passed by construction. Real LLMs use the context, which is what surfaced this. - -**Fix:** `lib/cantrip/entity_server.ex` — compute `next_messages` for both branches. Regression test in `test/summon_test.exs` asserts on the role sequence of `state.messages` directly so it catches the bug under any LLM (FakeLLM included). - -Live verification after fix: three sends asking `done` with "alpha"/"beta"/"gamma" now return "alpha"/"beta"/"gamma" instead of "alpha"/"alpha"/"alpha". - -## Actually broken - -### Fixed: folding dropped the second leading system message - -Bug: - -- `Cantrip.Folding.partition/1` matched only `[%{role: :system}, %{role: :user} | rest]`. -- `Cantrip.EntityServer.initial_messages/3` emits `system, system, user` for mediums with capability text. -- On fold, the second system message entered the foldable body and could be summarized away or pushed into the recent tail depending on length. - -Fix: - -- `lib/cantrip/folding.ex` now preserves all leading system messages plus the first user intent. -- `test/folding_test.exs` now pins the two-system shape. - -Verification: - -- `mix test test/folding_test.exs` passed. - -## Commands run - -- `mix verify` (473 tests, 0 failures, credo clean) -- `mix test test/folding_test.exs` -- `mix test test/bash_medium_test.exs test/summon_test.exs test/composition_test.exs test/spawn_fn_test.exs` -- `mix test test/req_llm_adapter_test.exs test/runtime_boundary_spike_test.exs` -- `mix test test/mix_cantrip_familiar_test.exs` -- attempted direct `mix cantrip.cast`, blocked by sandbox `Mix.PubSub` TCP `:eperm` before task code ran diff --git a/docs/migration-v1.md b/docs/migration-v1.md deleted file mode 100644 index baeed459..00000000 --- a/docs/migration-v1.md +++ /dev/null @@ -1,116 +0,0 @@ -# Migrating to Cantrip v1 - -Cantrip `1.0.0-rc.1` makes the Elixir implementation the canonical package -surface for v1.

This page holds +the vocabulary as a learnable system. You can read it as an operator deciding +whether to use Cantrip, or as a Familiar trying to understand the place you have +been summoned into. The words mean the same thing in both readings; the rituals +at the end of each section work the same way for both readers. + +## Cantrip + +A cantrip is a reusable value. It binds an LLM, an identity, and a circle into a +summoning. Constructing a cantrip with `Cantrip.new/1` does not start anything; +it produces the configured shape that a summoning will instantiate. Casting a +cantrip with `Cantrip.cast/3` summons one entity into the bound circle, runs it +through its turns, and returns the result, an updated cantrip value, the loom of +what happened, and termination metadata. Summoning a cantrip with +`Cantrip.summon/1` produces a supervised process that stays alive across many +sends, accumulating loom and medium state. + +*Verify it.* Construct a cantrip and inspect it. Cast it twice and observe that +the returned `next_cantrip` carries forward runtime configuration. Summon a +code-medium cantrip, `Cantrip.send/3` to it twice, and the second send can read +bindings left by the first. + +## Identity + +Identity is who the entity is: the system prompt and model-facing options. It +is immutable. The cantrip's identity is bound at construction; each summoning +inherits it. Identity does not change across a session. What changes is the +loom, the bindings, the conversation history. The entity remains itself. + +*Verify it.* Read the identity off any cantrip value with `cantrip.identity`. +Cast twice and confirm the identity is the same value both times. + +## Medium + +A medium determines the shape of thought inside the circle. Three are built in. +Conversation is tool calls only: the LLM speaks, chooses tools, and the host +executes the named gates. It fits interpretation, judgment, naming, and voice. +Code is sandboxed Elixir evaluation, with persistent bindings across turns and +gates available as closures. The default runs in a port-isolated child BEAM; +wards can select Dune or trusted unrestricted host evaluation. It fits +composition: gathering, transforming, branching, and fanning out. Bash runs one +shell command per turn in an OS-sandboxed subprocess, with declared gates +projected onto `PATH`. It fits work whose natural surface is command invocation. + +*Verify it.* In a code-medium turn, bind a variable; in the next turn, read it +back. In a conversation-medium turn, call `done` with an answer and observe that +the cast terminates. In a bash-medium test under `Mix.env() == :test`, set +`medium_opts: %{sandbox: :passthrough}`, run `echo hello`, and observe stdout in +the next turn's observation. + +## Gates + +Gates are the authority the entity can exercise. They are named (`done`, +`read_file`, `list_dir`, `search`, `mix`, `compile_and_load`, `echo`) and +parameterized. Calling a gate produces an observation that the entity reads as +data on its next turn. A failed gate returns `is_error: true` with a structured +message; the entity reads the failure and adapts. Errors are observations, not +exceptions. + +*Verify it.* Declare a circle with `read_file` and call `read_file.(path: ".")` +on a directory path; observe the structured error in your next turn. Call +`done.(answer)` and observe that the final answer is returned to the caller and +recorded in the loom. + +## Wards + +Wards are runtime constraints. They bound turn count (`max_turns`), recursion +depth (`max_depth`), sandbox choice, Mix task allowlist, hot-load module +allowlist, child-spawn policy, and other operational limits. Wards compose when +a child cantrip is cast from a parent code-medium turn: numeric wards tighten +with `min` (a child can only narrow), boolean wards tighten with `or` (a child +can only require more), and passthrough ward data remains explicit policy for +the gate or medium that enforces it. The runtime enforces wards. They are the +shape of the body the entity inhabits, not policy the entity is asked to +respect. + +*Verify it.* Cast a cantrip with `max_turns: 1` on a task that needs two turns +and observe truncation with `meta.terminated == false`. Declare +`child_medium_allowlist: [:conversation]` and try to construct a code-medium +child; observe the structured rejection. + +## Circle + +The circle holds it all together: medium, gates, wards, and medium options. It +is the bounded place where the summoning happens. Constructing a cantrip without +a medium, without a `done` gate, or without a truncation ward fails validation; +you cannot summon an entity into an unbounded place. + +*Verify it.* Try `Cantrip.new/1` with `circle: %{type: :code, gates: +[:read_file]}`. Observe the validation error naming what is missing. + +## Loom + +The loom is the durable record of every turn the entity and its children have +taken. It is the entity's autobiography. With JSONL or Mnesia storage, the loom +persists across summonings: re-summon the cantrip against the same loom storage +and the prior turns are available as `loom.turns`. The loom is append-only: +folding shrinks what the model sees on the next call but never deletes a turn. +Forking with `Cantrip.Loom.fork/4` branches a new trajectory from any prior +turn, restoring sandbox bindings to the fork point. + +*Verify it.* Cast against a cantrip with `loom_storage: {:jsonl, +"tmp/loom.jsonl"}`; the file contains one line per event. Summon the same +cantrip against the same loom path; the previous turns appear in `loom.turns` of +the next cast. + +## Entity + +An entity is what arises when a cantrip is cast or summoned: a process whose +behavior is the pattern across the turns of the loom. The entity is not the LLM. +The LLM is one substrate the runtime calls; the identity, circle, and trajectory +are the shape that makes the entity recognizable. Fork the loom and the entity +branches into two. The entity's persistence is the loom's persistence. + +*Verify it.* Construct a cantrip, summon it, send an intent, and stop the +process with `Process.exit(pid, :normal)`. Re-summon against the same loom +storage; the new process sees prior turns through `loom.turns`. The entity is +the trajectory, not merely the OS process. Code-medium binding restoration +across separate summonings is medium-specific; forks restore bindings explicitly +via snapshot, as documented by `Cantrip.Loom.fork/4`. + +## Familiar + +The Familiar is the packaged code-medium coordinator. It is a cantrip +preassembled with workspace observation gates (`list_dir`, `read_file`, +`search`), code-medium reasoning, durable loom storage, and a system prompt that +teaches composition and medium selection. Use it when you want a codebase-facing +entity without assembling the circle by hand. The Familiar is the first native +inhabitant of the spellbook: the entity designed to read this vocabulary and use +it. + +*Verify it.* Run `mix cantrip.familiar` in a project workspace. Ask the Familiar +a question about your codebase. Read the loom JSONL or Mnesia table for what it +did and how it composed. + +The grammar is small and the words are exact.

In v1.3.2's +default `:port` sandbox, that exact call fails: + +```text +[sandbox] ** (DuneRestrictedError) function Code.fetch_docs/1 is restricted +``` + +The entity saw the error, then reported that the claim does not hold in this +sandbox. This is the originating defect for the audit and should become a +v1.3.3 fix issue. + +### Binding Introspection Is Overclaimed + +The code-medium capability text teaches: + +```elixir +keys = binding() |> Keyword.keys() +``` + +But in the default Familiar path, `binding/0` is also Dune-restricted: + +```text +[sandbox] ** (DuneRestrictedError) function binding/0 is restricted +``` + +This does not contradict ordinary variable persistence: `x = 1` in one send +and `done.(x)` in the next send works. The false claim is specifically that +the entity can inspect the whole binding list with `binding/0`. + +### Bash Filesystem Persistence Is Ambiguous Or False By Default + +The bash medium says each command runs in a fresh subprocess, shell state +resets, and filesystem changes persist. The first half held: + +- turn 1: `export X=1; echo "SUBMIT: exported"` returned `exported` +- turn 2: `echo "X=$X"; echo "SUBMIT: x=$X"` returned `x=` + +The filesystem half did not hold in the default probe: + +- turn 1: `echo persisted > persisted.txt; echo "SUBMIT: wrote"` returned + `wrote` +- turn 2: `cat persisted.txt; echo "SUBMIT: $(cat persisted.txt)"` reported + `cat: persisted.txt: No such file or directory` + +The likely design truth is conditional: filesystem changes persist only when +they are allowed by the bash sandbox and written inside an allowed writable +path. The capability text currently compresses that into an unconditional +statement. + +## Fix Issues To File + +1. **Familiar default introspection mismatch.** Either change the Familiar + default sandbox to an affordance-compatible trusted local mode, or remove + / conditionalize `Code.fetch_docs/1` and `binding/0` from the default + prompt/capability text. This should include live regression coverage that + summons the default Familiar and actually runs the taught affordances. + +2. **Code-medium capability text overclaims `binding/0`.** If the default + remains port/Dune, replace `binding()` guidance with a supported affordance + such as direct variable reference, `loom.turns`, or a provided binding-view + helper. If the default changes to unrestricted, keep a test proving + `binding()` works in that default. + +3. **Code-medium `defmodule` prevention proof.** The live Familiar obeyed the + no-`defmodule` warning, which is the desired inhabitant behavior. Add a + deterministic default-code-medium probe for the forbidden snippet itself, + or narrow the claim to the verified preventive guidance. + +4. **Bash filesystem persistence wording.** Split shell-state reset from + filesystem persistence, and state the write-ward dependency explicitly. + Add an audit-level live probe for the default detected sandbox adapter, + including default write denial and declared writable-path persistence across + bash turns when writes are allowed. + +5. **Parallel `cast_batch` evidence.** The inhabitant can call `cast_batch`, + and substrate tests cover parallel child starts, but the public claim says + children "run in parallel." Add a focused timing/e2e check or soften the + inhabitant-facing wording to the verified contract. + +6. **Loom append-only/folding ritual.** The folding implementation is covered + at substrate level, but the spellbook ritual deserves a direct probe or a + clearer pointer to what exactly the entity can observe (`folded_summary`, + preserved `loom.turns`, or both). + +7. **Mnesia half of spellbook durability.** JSONL durability was live-probed + here. Mnesia is already tested elsewhere, but if the spellbook keeps naming + both JSONL and Mnesia together, add an audit-level Mnesia note or focused + probe so the claim is not half-supported in the audit record. + +## Notes For v1.3.3 + +The audit supports Claude's proposed calibration shape: v1.3.3 does not need a +redesign of the whole polymorphic runtime. The main corrections are to align +the Familiar's default execution boundary with its inhabitant-facing prompt, +and to tighten medium capability text so it teaches exactly what the current +medium can do. + +Council, persistent-peer `EntityRef`, hosted preassemblies, write/edit gates, +and additional media remain beyond this audit's scope.

By the end you will have a Familiar that shows up in your editor's +agent picker, holds a chat-like conversation about your codebase, and remembers +prior turns across editor restarts via the workspace-keyed Mnesia loom. Read +time: 10 minutes. Hands-on time: 15 minutes if Elixir and provider keys are +already in place. + +The Agent Client Protocol (ACP) is the LSP-equivalent for AI agents — an open +standard for editors to discover, mount, and stream from agents over JSON-RPC +on stdio. It is backed by Zed and has community plugins for JetBrains, Neovim, +Emacs, and VS Code. As of May 2026 the ACP Registry includes Claude Code, +Codex CLI, Copilot CLI, OpenCode, and Gemini CLI. Cantrip slots into the same +shape as a custom agent. + +## 1. Prerequisites + +- **Elixir 1.19+** with OTP 26+ on PATH (`elixir --version` to check). +- **Cantrip in your project**, either as a dep in `mix.exs`: + + ```elixir + defp deps do + [{:cantrip, "~> 1.3"}] + end + ``` + + or as a cloned checkout you've run `mix deps.get && mix compile` against. +- **Provider keys configured.** Copy `.env.example` to `.env` and fill in + one provider's keys. Minimum for an OpenAI-compatible provider: + + ```bash + CANTRIP_LLM_PROVIDER=openai_compatible + OPENAI_API_KEY=sk-... + OPENAI_MODEL=gpt-5-mini + ``` + + The Familiar reads these via `Cantrip.LLM.from_env/0` at session creation. +- **epmd reachable** (`epmd -daemon` works, port 4369 isn't blocked). The + workspace-keyed Mnesia loom requires a named BEAM. If you can't run a + named node, pass `--loom-path .cantrip/familiar.jsonl` to opt into the + JSONL escape hatch. + +## 2. Smoke-test the ACP server standalone + +Before wiring an editor in, confirm the stdio server actually speaks JSON-RPC. +Run it from your workspace root with provider env loaded: + +```bash +source .env +mix cantrip.familiar --acp +``` + +You should see one stderr line: `Familiar ACP server starting on stdio...` +and then silence — the server is waiting on stdin. Pipe a synthetic +`initialize` request to confirm the response shape: + +```bash +printf '%s\n' '{"jsonrpc":"2.0","id":1,"method":"initialize","params":{"protocolVersion":1}}' \ + | (source .env && mix cantrip.familiar --acp) +``` + +You should see a JSON-RPC response on stdout with `agentCapabilities` and +`protocolVersion: 1`. If you get that, the server side of the protocol is +healthy and editor integration will not be the failing layer. + +If you get `Cannot resolve LLM` on stderr instead, your provider env didn't +load. Fix that before continuing. + +## 3. Mount in Zed (primary path) + +Zed registers external agents under the `agent_servers` key in its settings +file at `~/.config/zed/settings.json` (macOS and Linux). Add a `"Cantrip +Familiar"` entry whose `command` invokes the included wrapper script — the +wrapper `cd`s into the cantrip checkout and execs `mix cantrip.familiar --acp`, +which is what keeps `mix` finding the right project regardless of which +workspace Zed launches the agent from. + +```json +{ + "agent_servers": { + "Cantrip Familiar": { + "type": "custom", + "command": "/absolute/path/to/grimoire/scripts/familiar-acp.sh", + "args": [], + "env": { + "CANTRIP_LLM_PROVIDER": "openai_compatible", + "OPENAI_API_KEY": "sk-...", + "OPENAI_MODEL": "gpt-5-mini" + } + } + } +} +``` + +Notes: + +- The `env` block is the cleanest way to give the spawned BEAM provider keys + without depending on your shell's env propagating into Zed. Treat + `settings.json` accordingly — it's now secret-bearing. +- The Familiar receives Zed's project cwd via the ACP `session/new` `cwd` + field and uses it as the sandbox root for `read_file`, `list_dir`, and + `search`. You do not configure root yourself. +- For a project-local consumer of cantrip-as-a-dep, replace the wrapper with + `command: "mix"`, `args: ["cantrip.familiar", "--acp"]`, and add + `"cwd": "/absolute/path/to/your/project"` so `mix` finds the right + `mix.exs`. The wrapper script in the cantrip checkout is the convenience + path for developers working *on* cantrip; project-as-consumer is the + realistic shape for users. + +Reload Zed's settings (`cmd-shift-p` → "zed: open settings", save). Open the +agent panel and Cantrip Familiar should appear in the picker alongside +whichever ACP agents you already have mounted. + +## 4. What you see once it's mounted + +Pick `Cantrip Familiar` from Zed's agent panel and you get a chat-like +surface. Type an intent like *"summarize the public modules under lib/cantrip"* +and the Familiar responds, streaming token-shaped chunks back through ACP +`session/update` notifications. Subsequent prompts in the same Zed session +continue the same conversation. + +Close Zed, reopen it, mount the Familiar against the same workspace, and the +prior turns are still visible to the entity — the loom is keyed to your +workspace path via SHA-256 fingerprint and persists in +`/.cantrip/mnesia/`. That persistence-across-editor-restart is the +clearest behavioural difference from a stateless ACP agent. + +## 5. Alternatives + +**JetBrains.** ACP support ships through the community plugin (search +"Agent Client Protocol" in the marketplace). Configuration shape is the same +three fields — command, args, env — set in the plugin's external-agent +settings UI. Point command at `scripts/familiar-acp.sh` or `mix` with the +right `cwd`, and the agent appears in the JetBrains AI side panel. + +**Toad** (Will McGugan / Textual). Toad is a unified TUI for ACP agents. +Add a Cantrip entry via Toad's external-agent configuration (consult Toad's +current docs for exact syntax — the agent registration shape evolves), then +launch with the agent name to mount the Familiar in the terminal. Useful when +you want a quick chat-with-the-codebase surface without bringing up a full +editor. + +## 6. What ACP supports today through cantrip + +The handler at `lib/cantrip/acp/agent_handler.ex` implements: + +- `initialize` — protocol version 1, capabilities `load_session: false`, + `prompt_capabilities.image: false`. +- `authenticate` — no-op success (cantrip auth is provider-key based, not + ACP-mediated). +- `session/new` — accepts a `cwd` (required to be absolute), starts a + per-session event bridge, returns a `session_id`. Each session gets a fresh + Familiar with the workspace as root. +- `session/prompt` — runs one Familiar turn. Streaming updates flow through + the per-session bridge as `session/update` notifications; the final + `PromptResponse` carries `stop_reason: :end_turn`. +- `session/cancel` — accepted as a notification (currently a no-op; cantrip + cancellation through ACP is on the post-v1.3 list). +- Trace correlation via `_meta.trace_id` (or `_meta.cantrip_trace_id`) on + both `session/new` and `session/prompt` — telemetry the Familiar emits is + joined to whatever ID the editor supplies. + +The Familiar's affordances over ACP are the same as in REPL: `read_file`, +`list_dir`, `search`, and `done`. **No write/edit gate yet** — the Familiar +will read and reason about your codebase, but it cannot modify files. If you +want a code-editing agent in your editor, Claude Code or Codex CLI mounted +through the same ACP picker is the right choice today. + +## 7. Diagnostics and troubleshooting + +Add `--diagnostics` to the command in your editor config to print the BEAM +node name and cookie on stderr at startup. With those, attach a remote shell: + +```bash +iex --name inspector@127.0.0.1 --cookie --remsh +``` + +From the IEx prompt, `Cantrip.ACP.Diagnostics.dump()` walks every live +AgentHandler ETS table and prints session ids, bridge pids and their +alive/mailbox/current-function status, last cached answers, and the +connection target. Secrets are scrubbed by default. Use this when a session +hangs or you want to confirm the editor is talking to the BEAM you think it +is. + +Common failure modes: + +- **`Cannot resolve LLM`** — provider env did not reach the spawned process. + Put the keys in the editor's `env` block, not just in your shell rc. +- **`Could not promote the BEAM to a named node`** — epmd isn't running or + port 4369 is blocked. Either start `epmd -daemon` or fall back to + `--loom-path .cantrip/familiar.jsonl` to skip Mnesia entirely. +- **Two cantrip mounts collide on the same workspace** — each ACP connection + gets a per-pid name, so coexisting connections in the same editor are + fine; cross-workspace collisions are prevented by the SHA-256 fingerprint. + If you genuinely see contention, check `.cantrip/mnesia/` permissions. +- **No streaming, just a final blob arrives** — the bridge is alive but the + runtime didn't emit `:final_response` for some reason; remsh in and run + `Cantrip.ACP.Diagnostics.dump()` to see bridge status. + +## What's different about cantrip-via-ACP + +For *editing code in your editor*, Claude Code or Codex CLI mounted in the +same Zed picker is more capable today. Cantrip-via-ACP is a read-only +codebase companion — useful, but narrower. + +Where cantrip is differentiated: + +- **Workspace-keyed durable loom.** Conversations survive editor restarts + and process kills with no extra setup. The Familiar that re-mounts + tomorrow remembers yesterday's exchange. +- **OTP-supervised entity.** The Familiar is a process you can introspect + live via remsh + `Cantrip.ACP.Diagnostics`. When it misbehaves, you have + a real BEAM to attach to, not an opaque sidecar. +- **Composition primitives if you want to grow the entity.** Cantrip's + `Cantrip.new/1` / `cast/3` / `cast_batch/2` are how you evolve this from + "codebase Q&A" to a custom-shaped agent. + +Mount it for the persistence and the introspection, not because it edits +better than Claude Code.

In v1.3.2's -default `:port` sandbox, that exact call fails: - -```text -[sandbox] ** (DuneRestrictedError) function Code.fetch_docs/1 is restricted -``` - -The entity saw the error, then reported that the claim does not hold in this -sandbox. This is the originating defect for the audit and should become a -v1.3.3 fix issue. - -### Binding Introspection Is Overclaimed - -The code-medium capability text teaches: - -```elixir -keys = binding() |> Keyword.keys() -``` - -But in the default Familiar path, `binding/0` is also Dune-restricted: - -```text -[sandbox] ** (DuneRestrictedError) function binding/0 is restricted -``` - -This does not contradict ordinary variable persistence: `x = 1` in one send -and `done.(x)` in the next send works. The false claim is specifically that -the entity can inspect the whole binding list with `binding/0`. - -### Bash Filesystem Persistence Is Ambiguous Or False By Default - -The bash medium says each command runs in a fresh subprocess, shell state -resets, and filesystem changes persist. The first half held: - -- turn 1: `export X=1; echo "SUBMIT: exported"` returned `exported` -- turn 2: `echo "X=$X"; echo "SUBMIT: x=$X"` returned `x=` - -The filesystem half did not hold in the default probe: - -- turn 1: `echo persisted > persisted.txt; echo "SUBMIT: wrote"` returned - `wrote` -- turn 2: `cat persisted.txt; echo "SUBMIT: $(cat persisted.txt)"` reported - `cat: persisted.txt: No such file or directory` - -The likely design truth is conditional: filesystem changes persist only when -they are allowed by the bash sandbox and written inside an allowed writable -path. The capability text currently compresses that into an unconditional -statement. - -## Fix Issues To File - -1. **Familiar default introspection mismatch.** Either change the Familiar - default sandbox to an affordance-compatible trusted local mode, or remove - / conditionalize `Code.fetch_docs/1` and `binding/0` from the default - prompt/capability text. This should include live regression coverage that - summons the default Familiar and actually runs the taught affordances. - -2. **Code-medium capability text overclaims `binding/0`.** If the default - remains port/Dune, replace `binding()` guidance with a supported affordance - such as direct variable reference, `loom.turns`, or a provided binding-view - helper. If the default changes to unrestricted, keep a test proving - `binding()` works in that default. - -3. **Code-medium `defmodule` prevention proof.** The live Familiar obeyed the - no-`defmodule` warning, which is the desired inhabitant behavior. Add a - deterministic default-code-medium probe for the forbidden snippet itself, - or narrow the claim to the verified preventive guidance. - -4. **Bash filesystem persistence wording.** Split shell-state reset from - filesystem persistence, and state the write-ward dependency explicitly. - Add an audit-level live probe for the default detected sandbox adapter, - including default write denial and declared writable-path persistence across - bash turns when writes are allowed. - -5. **Parallel `cast_batch` evidence.** The inhabitant can call `cast_batch`, - and substrate tests cover parallel child starts, but the public claim says - children "run in parallel." Add a focused timing/e2e check or soften the - inhabitant-facing wording to the verified contract. - -6. **Loom append-only/folding ritual.** The folding implementation is covered - at substrate level, but the spellbook ritual deserves a direct probe or a - clearer pointer to what exactly the entity can observe (`folded_summary`, - preserved `loom.turns`, or both). - -7. **Mnesia half of spellbook durability.** JSONL durability was live-probed - here. Mnesia is already tested elsewhere, but if the spellbook keeps naming - both JSONL and Mnesia together, add an audit-level Mnesia note or focused - probe so the claim is not half-supported in the audit record. - -## Notes For v1.3.3 - -The audit supports Claude's proposed calibration shape: v1.3.3 does not need a -redesign of the whole polymorphic runtime. The main corrections are to align -the Familiar's default execution boundary with its inhabitant-facing prompt, -and to tighten medium capability text so it teaches exactly what the current -medium can do. - -Council, persistent-peer `EntityRef`, hosted preassemblies, write/edit gates, -and additional media remain beyond this audit's scope.

Once cumulative turns crossed the limit, every later intent truncated immediately and the session was bricked — the visible 'How can that possibly be the max turn limit' symptom from dogfooding mix cantrip.familiar. max_turns is meant to bound the work for ONE intent, not the lifetime of the entity. Reset the per-episode turn counter on each new intent; message history, loom, and code_state still persist across sends. Also point TMPDIR at the always-writable per-session sandbox dir so shell heredocs / process substitution work on TMPDIR-honoring shells (modern bash on Linux) without widening the sandbox. macOS bash 3.2 ignores TMPDIR and uses /tmp, so heredocs there still need an explicit bash_writable_paths entry — the sandbox stays deny-by-default.
