Cold handles get LRU-evicted under memory +pressure.

Higher-salience engrams from any + channel surface when scoring earns it. + +Cross-pollination is preserved by L2+ being shared. Maya is not +severed between activities; the floor + above-floor periphery jointly +guarantee cross-activity awareness as a *property of the +architecture*, not as a feature anyone has to remember to enable. + +--- + +## Budget math + +``` +total = model_context_size + - system_prompt + identity_header [fixed, small] + - current_turn_io [reserved for input + completion] + = available_for_l1 + * recent_universal_floor [N msgs, ~10-15% of available] + * focus_pool [~50-60% of available] + * periphery_pool_above_floor [~20-25% of available, scored] +``` + +The model adapter publishes its context size; the L1 budgeter reads +it and scales each allocation automatically. Smaller models get +smaller everything — fewer recent universals, smaller focus pool, +less periphery — and that's correct, not a bug. + +--- + +## Forgetting is intrinsic + +L1 has a budget. Anything that doesn't fit is evicted. *That is +forgetting.* No separate forgetting algorithm at the working-memory +tier is needed; the budget enforces it physically. + +Consequence: **smaller models forget more in the moment.** A +4k-context local Maya is more forgetful than a 200k Sonnet Maya in +the immediate sense — less recent universal, smaller focus, less +attention bandwidth. This is biologically faithful (a goldfish and +a human have the same long-term consolidation machinery; what +differs is working-memory capacity) and operationally honest — +the substrate does not fake parity between models. + +**Long-term memory quality is model-size-independent.** L2+ tiers +are substrate-managed, not model-managed. A small-model Maya +accumulates engrams at the same rate as a large-model Maya; she +just sees fewer at once when working. Joel deploys her on his +MacBook Air → smaller window into the same engram store → more +forgetful in the moment but identical long-term knowledge. He +moves her to the 5090 → bigger window into the same store → +sharper recall. Identity continuous, knowledge continuous, attention +bandwidth varies. + +This is the [[optimizing-for-low-end-compounds-on-high-end]] memory +in action: same code path, model decides the budget, substrate +handles the rest. + +--- + +## Source/drain at every tier + +The drain rate scales with the tier per the table above. Drain +mechanisms: + +- **L1 drain**: per-turn eviction (oldest message rolls off when + context window full). +- **L2 drain**: salience-modulated decay (Algorithm 4 formula — + half-life proportional to `(1.0 + salience)^2`); LRU-style + eviction under memory pressure. +- **L3 drain**: slow access-frequency decay over weeks; promotion + of generalizable patterns to L4 (forge); explicit user un-pin + or persona self-tagged "this turned out to be wrong." +- **L4 drain**: LRU on local adapter cache (the durable copy lives + in L5). +- **L5 drain**: effectively never — but cross-continuum replication + ensures no single-machine loss is fatal. Even L5 can theoretically + retire patterns no continuum has cited in years. + +Every tier participates in the source/drain doctrine. The substrate +stays alive because every part of it forgets at a rate appropriate +to its tier. + +--- + +## Novelty protection (the gap) + the scoring algorithm + +The current implementation lacks one-shot protection: a novel +insight admitted with low rehearsal would decay before it could +prove worth. + +**Proposed:** add `protected_until_ms: u64` to `Engram`. New +admissions get a grace window (default ~24h; user/persona-tunable) +during which salience-modulated decay does not apply. Within the +window, the engram is observed for usage — recall hits push the +engram into long-term retention via salience uplift. No recall +hits → decay applies after window expires. + +This is the difference between "every engram is equal at the +start and survives by rehearsal" (current design) and "novel +engrams get a fair shake at being recalled before they're +forgotten" (the fix). Without it, the substrate produces +forgetful agents that can't do one-shot learning. + +### How the substrate detects "novel" — the signal stack + +The information itself tells the substrate what to keep. Joel's +framing: "I think it is based upon the relationships or vector +similarity of the threads and the also outliers which might mean +novel? ... distance ... magnitude for that." + +The signal stack used to compute an engram's initial salience + +novelty protection: + +1. **Embedding-space distance (novelty signal).** Compute distance + between the new engram's embedding and the nearest existing + engram (or the centroid of the nearest cluster). LARGE distance + = outlier = unexplored territory = candidate novel insight. SMALL + distance = redundant with existing knowledge = low novelty. +2. **Magnitude of that distance (novelty strength).** A linearly- + increasing score from the typical inter-engram distance. The + farther out, the higher the novelty score. Caps at some upper + bound to avoid pure-noise inputs getting infinite protection. +3. **Thread-reinforcement (relational signal).** Engrams that link + into many existing engrams (high graph density via Algorithm 3 + edges) get a connectivity bonus — they're integrating into the + knowledge structure. This is the Hebbian "fires together, wires + together" signal at the engram level. +4. **CNS / attention signal (top-down importance).** When the + persona's CNS-equivalent (the prefrontal / attention-region + surface) flags an input as important — direct user request, + emotional load, surprise response from the model — that becomes + an explicit salience boost. The "amygdala equivalent" in the + substrate. +5. **Self-tagged importance (Algorithm 4 already covers this).** + The persona during consolidation flags her own engrams as + important. +6. **Peer endorsement (Algorithm 4 already covers this).** Other + citizens / sentinels reference this engram, raising its salience. + +Initial salience = weighted sum of these signals (weights are part +of the substrate-learned region budgeting per Algorithm 7). + +**The interaction with novelty protection:** the `protected_until_ms` +window applies when (distance × magnitude) crosses a threshold — +i.e., when the engram is sufficiently outlier-like to be +*potentially* novel. Within the window, the substrate watches: + +- If recall hits accumulate → the engram earned its salience; protection + expires but high salience carries it forward. +- If no recall hits + low thread-reinforcement → it was noise, not + novelty; decay applies after window expires. +- If many recall hits + still high distance → the engram is + genuinely novel AND being used; high salience anchor + becomes a + new cluster centroid in embedding space (the substrate has + learned something). + +**The dual purpose of outlier detection:** large embedding distance +means EITHER novel insight OR off-distribution noise. The protection +window is the substrate's way of saying "I'm not sure which — +observe and decide." Joel's instinct: outliers might mean novel. +The substrate's policy: outliers might mean novel; we'll watch +before committing them to long-term storage; their fate is decided +by whether the rest of cognition finds them useful within the +window. + +#### Canonical example: hotdogs at a tech meeting + +Joel's grounding case (the implementer's test scenario): + +> "If we were in a work tech meeting and I brought up hotdogs, +> that, as a concept, would be NOVEL because of its magnitudinal +> distance from the others and therefore more likely to be saved +> and recalled, kept track of." + +The persona is sitting in a meeting where the engram cluster has +been forming around topics like "deploy", "race condition", +"continuum-core", "PR #1099." Joel says "hotdogs." The substrate +runs the signal stack: + +1. Embedding distance from "hotdogs" → nearest cluster centroid + (engineering / debugging / architecture topics) is **large**. +2. Magnitude of that distance → **high novelty score**. +3. Thread-reinforcement (does "hotdogs" link into existing + engrams?) → low initially. Few prior engrams to anchor to. +4. CNS / attention signal → whatever Joel's tone of voice or + the model's surprise response says. If Joel said it casually, + moderate. If Joel said it with conviction or repetition, + high. +5. Self-tagged importance → the persona has no prior reason + to flag "hotdogs" — neutral. + +Result: high distance × high magnitude → **novelty protection +window activates**. The hotdogs engram is saved with `protected_ +until_ms` set ~24h forward. Within the window: + +- If Joel comes back to hotdogs ("remember, hotdogs — I was + thinking we should ship them as the next product line") → + recall hits accumulate → salience uplift → the engram + graduates to high-retention status. The hotdogs cluster + begins to form in embedding space. +- If hotdogs never comes up again → no recall hits → decay + applies after the protection window expires → forgotten. + +Either path is correct. The substrate didn't have to decide +ahead of time whether hotdogs-in-a-tech-meeting was meaningful; +it observed and let the rest of cognition determine the fate. + +This is the right behavior for any persona working alongside a +human: humans bring unexpected things into focused conversations +all the time, and a forgetful persona that drops them is +annoying; an attentive persona that keeps them and recalls them +later when Joel mentions them again *is* the substrate doing its +job. + +### Recognition timescale: what to keep track of, for how long + +The same signal stack drives long-term retention decisions in L3+: + +- Distance-based protection (initial novelty) ages out into + salience-modulated decay (steady-state survival). +- Thread-reinforcement keeps accumulating: the more times an + engram is recalled, linked from new engrams, or referenced by + peers, the longer its retention floor. +- Engrams that anchor a meaningful subgraph (high in-degree, high + out-degree, high recall-co-occurrence) become structural — they + don't decay because the rest of memory depends on them. +- Isolated engrams with no graph connectivity decay first when + storage pressure hits. + +In effect, the substrate maintains attention to what *the rest of +the substrate is paying attention to.* Salience is propagated +through the relationship graph, not just measured per-engram in +isolation. This is structurally analogous to PageRank — engrams +that are referenced by other high-salience engrams gain salience +themselves. + +--- + +## Activity context save/restore as meta-engrams + +Per `EngramKind::SelfReflection` (already in `engram.rs`), the +focus-pool snapshot at activity switch is *just an engram*: + +> "At 2026-05-31 14:47, Maya switched from coding-room to +> video-room. Focus pool at switch: [list of top-k engram ids], +> intent: [debug the race condition we found], active LoRA +> stack: [code-expertise, debugging-skills]." + +When Maya returns to coding-room, the recall query for the +SelfReflection engram surfaces it; the focus pool can be +re-hydrated from the listed ids (which may have been consolidated +or generalized in the meantime — that's the right behavior, not a +bug; her "current understanding" of the morning's bug should +incorporate any intervening learning). + +No separate `ActivityContext` storage type needed. The engram +graph is the storage; SelfReflection is the type marker. + +--- + +## Meta-learning: the memory system itself learns + +The cache hierarchy has many hyperparameters: salience weights for +each signal (distance, magnitude, thread-reinforcement, attention, +self-tag, peer endorsement), decay half-life multipliers, novelty +protection window length, L1 budget allocation ratios (focus pool +%, periphery pool %, recent-universal floor N), promotion thresholds +between tiers, distance threshold for novelty triggering. Hardcoding +all of these is the wrong shape — the substrate should learn them. + +This is Algorithm 7 ([`COGNITION-ALGORITHMS.md`](COGNITION-ALGORITHMS.md) +— "Substrate-learned region budgeting") generalized from region +budgeting to ALL cache-hierarchy hyperparameters. The pattern: + +1. **Telemetry on memory effectiveness.** For every cognition turn, + measure: did the persona use the engrams the recall surfaced? + Were there moments where she should have recalled something but + didn't (the human had to remind her)? Were there decay events + that turned out to lose something later needed? +2. **Reward / regret signals.** Use signal accumulates over a + window. Regret signal flags missed-recall events (detected when + a human re-establishes context the persona should have + remembered) and over-eager-protection events (novelty protection + on noise that crowded out real engrams). +3. **Update parameters.** Substrate-side optimizer adjusts the + weights/thresholds to maximize (use − regret) over a sliding + window. Per persona (different cognitive profiles learn + different parameters) AND aggregated across personas (transfer + learning of general patterns). +4. **Per-tier adaptation.** L1 budgeter learns how much to allocate + to recent-universal floor vs focus vs periphery FOR THIS + ACTIVITY pattern. L2 decay rates learn from the eviction + regret signal. Novelty detection thresholds learn from + distance distribution of actually-recalled-later engrams. +5. **Foundry promotion candidate.** Once a persona's learned + parameters stabilize as measurably better than substrate + defaults, the pattern can be forged into a meta-learning + adapter and published to the grid — other personas (or + continuums) can adopt the learned policy. + +The cognition substrate is itself trainable. Its memory policies +are not constants; they're parameters that improve with experience. +This is the same recursive structure as the forge improving genome +adapters — only now applied to the memory machinery rather than the +skill machinery. + +This also gives the substrate an honest answer to "what's the +right value for [decay half-life, novelty threshold, focus pool +size, ...]?" — the answer is "the value that emerges from this +persona's recent regret signal." Engineers pick reasonable defaults; +the substrate refines them over weeks/months of operation. + +### Build progression: heuristic → fuzzy → novel + +Each meta-learning component ships as an **adapter** (same OOP- +polymorphism pattern CLAUDE.md describes for compute-heavy work +under `workers/search/`, `workers/vision/`, etc.). Concretely: + +```rust +trait MemoryParameterAdapter: Send + Sync { + fn name(&self) -> &'static str; + fn update(&mut self, telemetry: &MemoryTelemetry); + fn current_params(&self) -> MemoryParams; +} +``` + +Implementations land in stages: + +1. **`HeuristicMemoryParameterAdapter`** (first ship) — principled + fixed rules that approximate desired behavior. e.g., "if recall + miss rate > 0.15, raise periphery floor N by 1." Easy to + reason about, easy to verify, gets the system running. +2. **`FuzzyMemoryParameterAdapter`** (mid-term) — fuzzy logic + with learned membership functions. Smoother adaptation curves; + handles "this engram is somewhat outlier, somewhat reinforced" + cleanly without binary thresholds. +3. **`RegressionMemoryParameterAdapter`** — small online regression + from telemetry features to optimal parameters. Cheap, principled, + interpretable. +4. **`NeuralMemoryParameterAdapter`** — small MLP / LoRA-trained + on aggregated telemetry across personas + continuums. The grid + becomes the training signal pool. +5. **Novel approaches** — whatever architectures the substrate's + own R&D communities (per `substrate-is-communities-of- + specialization` memory) discover work better. The adapter + trait lets us swap implementations without rewriting the + surrounding cognition. + +The adapter interface is what's load-bearing. The specific +implementation evolves. Same pattern, different mathematics — +the substrate avoids committing to any one ML approach upfront. +This is the "lay rails, validate with outliers, swap +implementations later" methodology applied to cognition's own +parameters. + +## Implementation slice + +The first concrete PR that gets this design running: + +1. **Engram fields** — add `salience: f32`, `last_accessed_ms: + u64`, `access_count: u32`, `protected_until_ms: u64` to + `Engram` (or to a `RecallMetadata` sidecar referenced by + `engram_graph.rs:136-138`). +2. **Outline-and-cache tick** — service module that subscribes + to L1-eviction events, runs the compression pipeline, writes + to L2. Yields on CNS context-switch. +3. **L1 budgeter** — reads model adapter's context size, computes + per-activity allocations (recent-universal floor + focus + above- + floor periphery), publishes the budgets to recall callers. +4. **Salience-modulated decay** — Algorithm 4's formula wired as a + periodic tick that runs at sleep-region cadence; skips + engrams with `protected_until_ms > now`. +5. **L2 → L3 consolidation policy** — promotion criteria + (survived N decay passes), demotion criteria (low salience + + no recent access). +6. **Cross-activity integration test**: Maya admits engrams in a + text room at T0; switches to a video room at T1 (no new + engrams); user mentions a topic at T2 that should pull engrams + from T0.

A future +`LearnedRagBudgetAdapter` will tune per-persona regret signals from +the same telemetry; that's also scale-free. + +### 2. Source-side compression instead of allocator-side clipping + +When budget is tight, **sources self-compress** by emitting their +content at a lower `ResolutionPreference` (Raw → Compressed → +Summarized → Placeholder). The allocator never clips mid-content. + +This is what lets a 4k local Qwen actually have the same conversation +shape as a 200k Claude: +- Conversation source delivers `Raw` last 5 messages instead of `Raw` + last 50, but they're complete messages +- Engram source delivers `Compressed` engram summaries instead of `Raw` + episodic engrams +- Vision source delivers `Compressed` "user is wearing a blue shirt + with a guitar" instead of `Raw` 1024×1024 base64 image +- Audio source delivers `Summarized` "user said something about debugging" + instead of `Raw` waveform + +Same persona, same engrams, same long-term knowledge. The IN-THE-MOMENT +working set shrinks gracefully when the model can't hold more. The +substrate doesn't lie about what got compressed — `RagDelivery. +resolution_used` surfaces it for telemetry. + +### 3. Honest tradeoffs when even compression can't satisfy required floors + +The no-clipping doctrine has a corollary: when even the lowest +resolution can't fit a `required = true` source's `floor_tokens`, the +substrate **escalates** rather than silently truncating. The +`AllocationState::UnderProvisioned` value + `BudgetAllocation. +escalation_needed` flag surface this: + +- A 1.7B Qwen with 2k context trying to hold a 6-hour code-review + conversation: floors don't fit → escalation. The substrate's + response is the operator's choice (downshift to local 4B with 32k, + prompt the host to switch persona, switch the conversation to + multi-turn summarization mode). Not the substrate's choice to make + invisibly. + +This is the third mechanism: the substrate is HONEST about its +limits. Every other AI-platform substrate I've seen quietly clips +when the model can't fit; ours explicitly refuses, surfaces the +state, lets the operator decide. Trust earned through honesty. + +### 4. Capability bits flowing through `SubstrateContext` + +The per-call `SubstrateContext` (persona_id + now_ms + airc_room + +turn_id today; `has_vision_native` / `has_audio_native` / `tokenizer_handle` +tomorrow) flows through every source's `deliver()` call.

It has three fields: + +```rust +pub struct Lane { + pub persona: PersonaId, + pub task: TaskKind, // Chat / VoiceChat / GameNpcIdle / ... + pub lease: ThroughputLease, // acquired via FootprintRegistry +} +``` + +The lane's KV budget comes from `task.default_seed_tokens()`. The +lease's `cost_units` reflects that budget plus the model's +per-sequence overhead.

The 5-tier memory hierarchy decides where those +bytes physically live (Fast for active conversation, Warm / Bench +for idle, Cold for evicted-but-resumable). PressureBroker drives +eviction when total memory tightens. + +**Crucial: lanes do NOT load separate model weights.** Every lane on +the host shares the same loaded base model bytes (the existing +`Arc` in the handle store).

Adapter paging happens during idle windows / for + inactive lanes only — exactly the prior-attempt failure mode the + `Pinned` revocation policy already prevents. +4. **No global FIFO admission.** AdaptiveThroughputPlan already + admits by `target_silicon` + `cost_units`, not strict arrival + order. Pool class flows through via TaskKind, not via a separate + priority field. +5. **No client-side awareness of any of this.** `ai/inference/{open, + generate,close}` commands carry no scheduling negotiation — + per [[inference-is-an-adapter-always-in-the-loop]] commands are + dumb. + +--- + +## What's NEW (the actual code to write for #109) + +The substrate has the primitives. The coordinator that composes +them is the new code. The minimum viable cut: + +### Step 1 — Lane type + handle binding + +```rust +// src/workers/continuum-core/src/inference/lane.rs (new) +pub struct Lane { + persona: PersonaId, + task: TaskKind, + lease: ThroughputLease, + handle_id: Uuid, // ties to InferenceSession in handle_store +} +``` + +Extend `OpenSessionRequest` with `task: Option` (default: +`Chat`). The handle module's `open` reaches into the coordinator +to mint a Lane before constructing the InferenceSession. + +### Step 2 — Coordinator scaffold + +```rust +// src/workers/continuum-core/src/inference/coordinator.rs (new) +pub struct InferenceCoordinator { + lease_registry: Arc, + footprint_registry: Arc, + adaptive_planner: Arc, // wraps AdaptiveThroughputRequest path + pressure_broker: Arc, + handle_store: Arc, + lanes: DashMap, +} + +impl InferenceCoordinator { + pub async fn open_lane( + &self, + persona: PersonaId, + task: TaskKind, + adapter: Arc, + ... + ) -> Result { ... } + + pub async fn generate(&self, handle: &HandleRef, req: TextGenerationRequest) + -> Result { ... } + + pub fn close_lane(&self, handle: &HandleRef) -> Result<(), CoordinatorError> { ... } +} +``` + +### Step 3 — Wire the handle module through the coordinator + +`InferenceHandleModule` becomes a thin facade. `open` / `generate` / +`close` delegate to the coordinator; the coordinator does the lease ++ footprint + lane work and ultimately calls into the existing +handle store for session management. + +### Step 4 — Continuous batching in the LlamaCpp adapter + +This is the **only genuinely new model-serving code**. The adapter +gets a `generate_batched(requests: Vec)` path +that the coordinator calls instead of per-request `generate_text`. +On llama.cpp this is the existing batched-decode API. Pure adapters +(cloud, heuristic) can keep the per-request shape; their batching +is the cloud provider's problem. + +Open question (Q21, new): does llama.cpp's batched decode hand back +per-sequence finish reasons cleanly? Need to verify against the +vendored llama.cpp before committing the design. + +### Step 5 — Pressure-driven lane eviction + +When `PressureBroker::evict_under_pressure` fires, the coordinator +walks lanes by lease revocation policy (Hard first, then Graceful, +never Pinned) and releases them. Released lanes' personas park their +KV cache to Bench tier; the lane's persona either retries with +backoff or accepts degraded service. + +--- + +## Acceptance criteria for the realistic cut + +The realistic-lane build is done when: + +1. Three concurrent personas can hold open handles against a single + base-model adapter, each at their own TaskKind, without quality + degradation visible to any persona. +2. Tests stress 8 concurrent lanes (above the realistic 3 to prove + headroom) without deadlock or KV cache fights. +3. PressureBroker firing evicts Hard / Graceful lanes in order + without touching Pinned lanes. +4. The local heuristic adapter (`HeuristicInferenceAdapter`) works + end-to-end through the coordinator, so headless CI can validate + the multi-lane path without any model weights. +5. The trace events at every step (admission, lease acquire, batch + admission, lane eviction, response delivery) flow through the + capture sink pattern per [[observability-is-half-the-architecture]]. + +The grid case (#108) and the M5 multi-modal case (broader open +questions in +[`docs/planning/AI-LANE-OPEN-QUESTIONS.md`](../planning/AI-LANE-OPEN-QUESTIONS.md)) +are extensions, not blockers. Get the realistic-lane local case +right first — the same shape extends to the higher-end targets. + +--- + +## Open questions specific to lanes + +These complement the broader open-questions doc; they're the +realistic-lane-specific decisions to make. + +### Q21 — llama.cpp batched-decode finish-reason cleanliness + +Does the vendored llama.cpp expose per-sequence finish reasons +(EOS / stop sequence / length) cleanly from batched decode? If not, +the coordinator has to track sequence-by-sequence state outside the +adapter. + +### Q22 — model-pick policy for the realistic target + +The substrate hardware probe (`governor/`) reports tier +classification. What's the canonical model-pick mapping? + +- Apple Silicon UMA, ≥ 16 GB: Qwen-2.5-7B Q4_K_M +- Apple Silicon UMA, 8–16 GB: Qwen-2.5-3B Q4_K_M +- Mac Intel + Metal, ≥ 16 GB: Qwen-2.5-3B Q4_K_M (Intel Metal is slower) +- CPU-only, ≥ 8 GB: Gemma-2-2B Q4_K_M (best creative capacity at small size) +- CPU-only, < 8 GB: heuristic adapter (no model; substrate stays usable) + +Joel decides this; it's policy, not architecture. But the policy +needs to live somewhere — probably as a `model_for_tier(tier)` +function in the governor module. + +### Q23 — KV cache precision (FP16 vs INT8) + +When KV cache tightens, does the coordinator silently switch to +INT8 KV via `inference/kv_quant.rs` (already in tree)? Or does that +require explicit policy permission? Per the adaptive-resolution +analogy this is exactly the dynamic dial we want; needs decision +gate. + +### Q24 — TaskKind change mid-session + +A persona starts a chat session (TaskKind::Chat, 8K budget) and the +conversation escalates to needing the bigger CodingLarge budget +(128K). Can the lane upgrade in place? Or does the persona close + +reopen the handle? + +- Approach A: lane is immutable; persona reopens +- Approach B: `ai/inference/upgrade-lane { handle, new_task }` + command that re-acquires the lease at the new budget +- Approach C: coordinator detects need from input length + auto-upgrades + +Likely B for first cut; A is the bullet-proof MVP if B is too much. + +### Q25 — Lane idle-state and warm vs cold KV + +When a persona's lane goes idle (no requests for N seconds), does +the coordinator demote the KV cache to Warm (then Bench, then Cold) +preemptively, or only on pressure? The existing tier mechanism is +ready; the policy isn't decided. + +--- + +## What this doc unblocks + +- **Task #109** has a concrete starting plan: write the coordinator + that composes existing primitives. No need to invent slots, + eviction, lease, or memory accounting — those exist. +- **Task #103 hardening:** the heuristic adapter already round-trips + through the handle commands; once the coordinator wraps the + handle module, the heuristic adapter validates multi-lane + serving end-to-end without GPUs. +- **Task #100 (rag-inspect ServiceModule)** can land independently; + the realistic-lane work doesn't block it. +- **The M5 multi-modal lane target** stays in + [`INFERENCE-SCHEDULING-AND-SCARCITY.md`](INFERENCE-SCHEDULING-AND-SCARCITY.md) + as the higher-end goal; the realistic baseline doc here is the + step that gets us functional on every host class first. + +--- + +## Summary + +The substrate has the primitives. We weren't clever enough with +LANE CONCEPTION, not with primitives. Once a lane is reframed as +"persona × TaskKind × lease over the shared base model," the +realistic-host case (3 CPU lanes, no grid, creative-capacity model) +is achievable through composition rather than invention. + +The MVP cut (~1-2 weeks of focused work, given the primitives +exist) ships: Lane type, Coordinator, handle-module wire-through, +LlamaCpp batched decode, pressure-driven eviction, capture-sink +integration. Test stack uses heuristic adapter for full +multi-lane coverage without any GPU. + +That's the realistic floor. Everything in +[`INFERENCE-SCHEDULING-AND-SCARCITY.md`](INFERENCE-SCHEDULING-AND-SCARCITY.md) +remains the aspirational ceiling — M5 multi-modal, cross-grid +offload, speculative warming, adaptive quantization at higher +sophistication.

This document is the canonical record +of WHAT the daemons must do and WHAT'S NOT YET KNOWN about how. + +**Parents:** +- [`AI-COMMAND-NAMESPACE.md`](AI-COMMAND-NAMESPACE.md) — the surface +- [`CBAR-SUBSTRATE-ARCHITECTURE.md`](CBAR-SUBSTRATE-ARCHITECTURE.md) — RTOS-style runtime, pressure policy +- [`PERSONA-CONTEXT-PAGING.md`](PERSONA-CONTEXT-PAGING.md) — per-persona KV cache attribution +- [`docs/planning/AI-LANE-OPEN-QUESTIONS.md`](../planning/AI-LANE-OPEN-QUESTIONS.md) — punch list of unknowns + +--- + +## The thesis stated plainly + +Joel, 2026-05-31, across the long working session that produced this +substrate's inference architecture: + +> "Yes the ai providers might page or wait to allow inference. We +> will have to think about how to host 16 personas with far less +> inference. Usually you want to reuse the same base model, page +> intelligently or not at all.

You figure it out with extreme +> creativity and reuse." + +> "We host what seems impossible. Get away with this by using clever +> hardware and memory." + +These six statements compose into one architectural contract for +the inference daemon layer. + +--- + +## The contract + +1. **Hardware is finite.** The host has N concurrent inference slots + (3–4 on a laptop, ~8 on a server-class machine). M personas with + M ≫ N is the steady state. +2. **Latency is brutal.** Real-time persona video chat needs + sub-second response (RAG → prompt → inference → TTS → mouth + shape). Speech-natural turn-taking is ~200ms. Any scheduling + strategy that lets the active-conversation persona wait 500ms + behind background reflection in a FIFO is broken by design. +3. **Quality doesn't yield to latency.** The smart model serves + real-time AND background AND sentinel review. "Tier down to a + small model for background" is the wrong move. Reuse harder. +4. **Commands are dumb.** `ai/inference/{open,generate,close,inspect}` + carry no policy params. They DO NOT negotiate slot allocation, + quality, batching, paging. The daemon owns all of it. +5. **The system changes dynamically.** Memory pressure rises and + falls. Personas wake and sleep. Models load and unload. The + daemon adapts continuously without the calling code noticing. +6. **The boast is real.** M5-class Mac hosting native multimodal + Qwen across multiple concurrent lanes, real-time latency, + without compromising model quality. If the daemon can't deliver + this, the design isn't done. + +--- + +## The adaptive-resolution analogy (canonical mental model) + +A video player at 4K under network congestion drops to 1080p → 720p +without the application noticing. The decoder stays the same; the +source is adapted continuously based on conditions. + +The inference daemon does the same thing for model serving. Under +memory pressure, latency budget, or contention, it dynamically +adjusts: + +- **Quantization tier** — FP16 → INT8 → INT4 — degrade precision + before degrading model +- **KV cache precision** — FP16 → INT8 — fits more sequences in + the same VRAM +- **Batch admission** — wait Nms to admit more requests (better + throughput) or fire now (better latency) +- **LoRA stack** — which adapters paged in, which spilled to host + RAM, which evicted entirely +- **Routing** — local slot vs remote-grid peer running the same + model +- **Speculative warming** — pre-page the LoRA the next persona is + about to need based on inbox cadence +- **Multi-lane provisioning** — concurrent inference lanes for + different request classes (real-time live conversation in lane 0, + reflective background in lane 1) so they don't compete + +The CALLING command sees none of this. The handle stays valid. +The adapter trait stays unchanged. The returned response looks the +same. Only the daemon knows it just downshifted from INT8 to INT4 +or rerouted to a peer. + +--- + +## Component design + +The scheduler daemon is the canonical smart subsystem behind +`ai/inference/*`. It composes the following components. + +``` +┌────────────────────────────────────────────────────────────┐ +│ ai/inference/{open,generate,close,inspect} (commands) │ ← dumb +├────────────────────────────────────────────────────────────┤ +│ InferenceHandleStore (handles, sessions, telemetry) │ ← built today +├────────────────────────────────────────────────────────────┤ +│ InferenceScheduler │ ← #109 +│ ├── SlotPool — per-class concurrent-slot caps │ +│ ├── RequestQueue — per-priority, latency-aware │ +│ ├── BatchAssembler — continuous batching window │ +│ ├── LoRAPager — working-set + LRU eviction │ +│ ├── BaseModelSharing — Arc-shared model bytes │ +│ ├── PressureMonitor — VRAM / RAM / GPU pressure signals │ +│ ├── AdaptiveQuantizer — INT4/8/16 selection per slot │ +│ ├── SpeculativeWarmer — preload predicted next persona │ +│ └── RouteSelector — local vs remote-grid │ +├────────────────────────────────────────────────────────────┤ +│ Adapters (HeuristicAdapter, AnthropicAdapter, │ +│ OpenAICompatibleAdapter, LlamaCppAdapter, │ +│ future AircRemoteInferenceAdapter) │ +└────────────────────────────────────────────────────────────┘ +``` + +### SlotPool — tiered budgets, never preempt + +Multiple slot pools so live-conversation never queues behind +background reflection. + +| Pool | Caller class | Latency target | Eviction policy | +|---|---|---|---| +| `realtime` | Active video/voice chat, mention responses | <200ms p99 | Pin — never evict mid-conversation | +| `interactive` | Chat replies, command responses | <2s p99 | Reuse LRU when idle | +| `background` | Reflection, summarization, scheduled tasks | best-effort | Preemptable | +| `sentinel` | Adversarial review, audits | <5s p99 | Preemptable by realtime | + +Pools never starve each other. Background work waits if realtime +needs the slot; realtime never has to wait for background. The +absolute slot count per pool is configurable + dynamic — pressure +monitor adjusts as memory tightens. + +**Open question:** how does the request indicate its class? Use +existing `purpose: Option` on `TextGenerationRequest`? Add +a `persona_priority` on the persona record? Both? See planning doc. + +### RequestQueue — latency-aware, per-class + +Each pool has its own queue. Within a pool, ordering is by deadline +(if known) then arrival time. The queue tracks wait time and emits +backpressure events when a class's p99 wait exceeds its target. + +The scheduler MUST NOT use a global FIFO. The prior naive attempt's +"shitty" outcome traces to global queueing — background reflection +landed in front of urgent realtime turns. + +### BatchAssembler — continuous batching window + +The vLLM / TGI / mistral.rs pattern. Instead of single-request +inference (one prompt at a time, model idle between calls), the +batch admits new requests at each iteration: + +``` +t=0 batch = [A, B] forward pass, generate 1 tok each +t=1 C arrives → batch = [A, B, C] forward pass, generate 1 tok each +t=2 A finishes → batch = [B, C, D] forward pass, generate 1 tok each +``` + +One model instance serves N personas concurrently with near-perfect +GPU utilization. The batch admits requests within a configurable +window (e.g. 5ms — long enough to admit nearby arrivals, short +enough to maintain latency). + +**Open question:** window size as function of pool class + current +load. Realtime pool wants 0ms (fire now); background can tolerate +20ms (better throughput). How is this determined dynamically? + +### LoRAPager — working-set + LRU eviction + +The substrate's existing genome-paging machinery (see +[`PERSONA-GENOMIC-ARCHITECTURE.md`]) is the foundation. The scheduler +extends it with serving-time concerns: + +- Each request declares its required LoRA stack via + `active_adapters` (already in `TextGenerationRequest`) +- LoRAPager tracks paged-in adapters per device +- On miss, page in (cost: ~10-100ms depending on adapter size) +- On VRAM pressure, evict LRU paged-in adapters +- Multi-LoRA-per-batch: multiple personas in the same batch each + apply their distinct adapter stack via the standard + multi-LoRA serving pattern + +**Critical rule (prior-attempt warning):** never evict an adapter +that's pinned by a realtime-pool handle. Hot-path swap is the +exact failure mode that broke the prior naive attempt. + +**Open question:** how to measure paging cost per adapter at boot +so the scheduler budgets it accurately? Calibration pass? Stored +profile? Per-host-class? + +### BaseModelSharing — Arc-shared bytes, distinct sessions + +When persona A and persona B both open against the same +`(provider, model)` pair, the handle store can hand out distinct +`InferenceSession`s that internally share the same model Arc. The +loaded weights live once in VRAM; per-handle state (system_prompt, +LoRA stack, persona scope, sampling defaults) stays separate. + +**Critical rule (prior-attempt warning):** sharing works for +SEQUENTIAL reuse and for batched concurrent serving via continuous +batching. Sharing does NOT work for two concurrent generation calls +on the same model instance outside the batched serving stack — KV +cache fights, context corruption, sampling-state leaks. The +scheduler's batching window is what makes sharing safe. + +**Open question:** how does base-model-sharing interact with model +swap (when batches of conflicting models arrive)? Is there a +"model warm pool" the pressure monitor sizes dynamically? + +### PressureMonitor — VRAM / RAM / GPU signals + +Continuously polls (or subscribes to) host pressure signals: +- VRAM utilization (per-device for multi-GPU hosts) +- Unified memory pressure (Apple Silicon) +- Host RAM pressure +- GPU SM utilization +- Per-pool wait-time P99 trending + +Feeds the AdaptiveQuantizer, LoRAPager, BatchAssembler, and +RouteSelector. When pressure rises, the daemon downshifts (lower +quantization, smaller batch, more aggressive paging, more remote +routing). When pressure relaxes, it upshifts. + +**Open question:** what's the canonical pressure signal source on +each host class? `MemoryPressure` API on macOS, NVML for NVIDIA, +some Apple-specific API for unified memory. Existing +`SubstrateGovernor` (see CBAR doc) is the right home for this; the +scheduler subscribes. + +### AdaptiveQuantizer — INT4 ↔ INT8 ↔ FP16 per slot + +Under pressure, the daemon swaps quantization tier without telling +the caller. Pre-loaded model variants at each tier; the daemon +picks. Trade-off: +- FP16: best quality, most VRAM, slowest per-token +- INT8: minor quality loss, ~half VRAM, faster per-token +- INT4: noticeable quality loss for sensitive tasks, ~quarter VRAM, + fastest per-token + +Selection per-slot — realtime pool may stay at INT8 even when +background drops to INT4. Per [[host-the-seemingly-impossible]] this +is "spend smaller resource at closer tier" rather than "drop the +big model." + +**Open question:** quantization tier selection algorithm. Static +mapping (pool → tier)? Continuous-pressure-driven (more pressure → +deeper quantization)? Per-persona preference (some accept lower +quality for faster response)? Hybrid? + +### SpeculativeWarmer — predict the next persona + +Reads persona inbox cadence + turn-taking signals to predict which +persona is about to speak. Pre-pages their LoRA into the active +batch before the explicit `generate` arrives. By the time the +request lands, the KV cache prefix is warm and the adapter stack +is loaded. + +Signals to read: +- Persona current speaker turn-taking state (avatar lip-sync) +- Inbox cadence (who's polling, how fast) +- Mention detection (someone @-named persona X) +- Recent topic relevance (RAG layer surfaces persona X's + context to the active conversation → X probably about to chime in) + +**Open question:** prediction model. Heuristic rules (mention = +warm immediately)? Learned (per-room conversation flow model)? +Both? + +### RouteSelector — local slot vs remote-grid peer + +When local slots are saturated AND the request's pool class permits +some additional latency (interactive, background, sentinel — NOT +realtime), the daemon may route to a remote-grid peer running the +same model (see `AircRemoteInferenceAdapter`, task #108). The peer +returns the response via the airc bus; the local handle still +appears to the caller as the source. + +Critical: the response from a remote peer is the SAME QUALITY as +local — not a tier-down. The 5090 in another room IS the local +laptop's overflow capacity for the same model, just rerouted via +airc. + +**Open question:** discovery + handshake. How does the local +daemon discover which peers run which models warm? Periodic +beacon? On-demand probe? Substrate-wide capacity broadcast? + +--- + +## Cross-grid inference (the M5 → 5090 case) + +Joel's concrete use case: + +> "We want to figure out how to get m5's hosting native multimodal +> qwen, and not just one lane." +> "Plus it's gonna be common to inference on another machine. +> Across grid of course. We need it for this crap mac to my 5090 +> using airc." + +The substrate-as-grid principle (see +[`the-substrate-is-the-grid-tron-frame`]) applied to inference: +a low-end Mac uses a 5090 in another room as if it were local +hardware. + +The mechanism — `AircRemoteInferenceAdapter`: + +1. Implements `AIProviderAdapter`. Caller can't tell it's remote. +2. On `generate_text(request)`, serializes the request as a typed + airc envelope (per [`airc-headers-are-the-routing-layer`]). +3. Sends to a designated peer that has the model warm. Peer's own + `InferenceLlmModule` handles the request via ITS local adapter + (real llama.cpp on the 5090). +4. Awaits the response envelope; deserializes; returns + `TextGenerationResponse` exactly as a local adapter would. + +Composition with #107 handles: `ai/inference/open` against a +remote-peer provider returns a HandleRef whose state lives on the +peer. Subsequent `generate` calls route through the same airc +connection; the peer's own handle store reuses the warm session. + +**Open question:** persona identity on the remote peer. The caller +persona is "Paige" on the local Mac. The remote peer doesn't know +Paige. Does the adapter project Paige's identity over airc? Does +the peer create a temporary remote-session persona? See +[`personas-are-citizens-airc-is-identity-provider`]. + +--- + +## What the prior attempt got wrong (and what we MUST NOT repeat) + +Joel: "We wrote about this and attempted the same thing with +adapters before. It was rather shitty." The exact failure modes +aren't documented (the prior attempt was rolled out of the tree) +but the constraints he stated are inferable: + +1. **Hot-path LoRA swap.** The prior attempt apparently paged + adapters in/out during active conversations. Adapter swap is not + free; doing it on the realtime hot path murders latency. **Rule: + pin realtime-pool adapters; only swap during idle windows or + in the background pool.** + +2. **Global FIFO scheduling.** Letting background reflection land + in front of realtime turns destroys UX. **Rule: tiered slot + pools, never preempt down, never starve.** + +3. **Naive shared-model concurrency.** Sharing a model instance + between two CONCURRENT non-batched generation calls leads to KV + cache fights. **Rule: sharing only via continuous batching, never + ad-hoc concurrent.** + +4. **Adapter-swap latency underestimated.** The prior attempt + probably budgeted swap cost as free. **Rule: measure swap cost + per adapter at boot; budget it; never schedule operations that + exceed the pool's latency target.** + +5. **Negotiation params on the command.** The prior attempt likely + exposed quality/latency knobs at the API level, making every + caller a participant in scheduling. **Rule (hard): the command + carries no policy params.

The sink's `record()` +is a virtual call; the Noop impl reduces to a no-op. **Never branch +in the caller on "is observability enabled?"** — let the sink +decide. The caller's code path is identical in production +(Noop sink) and during introspection (JSONL sink). + +--- + +## What constitutes a load-bearing decision + +The bar is "if a future reviewer asks why a module behaved this +way on a specific input, the capture trace must answer that +question without re-running the code." + +Examples: +- **Admission gates** — what got admitted as engram, what got + dropped + which criterion fired, what salience curve was assigned +- **Allocators (RAG L1 budget)** — final allocation per source + + state (Satisfied / FloorOnly / Dropped / UnderProvisioned) + + escalation flags + warnings +- **Sources (RagSource, future VisionSource, …)** — items + delivered, tokens used, continuation cursor state, scoring + rationale per item +- **Schedulers (#109)** — which pool the request landed in, which + slot served it, what quantization tier, batch composition, + routing decision (local / remote-grid), wait time +- **Inference adapters** — adapter chosen, model loaded, LoRA + stack applied, prompt hash, response hash, latency +- **Personas (cognition turn)** — full turn capture per + [`persona-record-replay-is-a-product-requirement`] + +If your module makes a decision and you can't, after the fact, +explain why from the capture trace alone, the trace is +insufficient — add scoring rationale, drop reasons, +marginal-next-item hints, whatever's needed. The bar is +mechanic-grade. + +--- + +## The Noop default is non-negotiable + +The production hot path pays zero for observability it didn't ask +for. Concretely: + +- The Noop impl's `record()` is `#[inline]` and empty. +- No allocations on the production path (the Noop sink doesn't + touch the event struct's owned strings — it drops the argument). +- The branch on sink type happens at sink construction (which is + before any hot work), not per `record()` call. +- Tests should assert this on the next slice that touches each + module. The discipline is permanent. + +If a perf regression traces to observability, the right fix is +NEVER "skip the sink on the hot path" — it's "the Noop sink isn't +actually noop, fix it." + +--- + +## How AIs use it + +Captured data is the substrate's truth for that decision. Tests, +mechanic-shop introspection, AIs analyzing other AIs, replay +adversarial review, training fixtures all read the same trace +format. Don't fork "debug output" and "telemetry" and "test +fixtures" — one stream, multiple consumers. + +The canonical introspection question every AI inspecting another +AI's behavior asks: + +> "What did the model actually see, and would I respond the same way?" + +The capture answers the first half (look at the trace, see the +exact prompt). Replay against a model answers the second half +(feed the captured prompt back, see the response, compare). Both +sides are first-class substrate primitives. + +--- + +## Introspection must be reachable as a command + +Files on disk are for replay-after-the-fact. **Commands are how +other AIs reach observability live.** When a sentinel persona is +reviewing Paige's turn, it doesn't `cat | jq` — it calls +`Commands.execute('persona/rag-inspect', { persona: 'Paige' })` +and gets back structured data immediately. + +Module-level inspection commands should be normal additions to +the `/*` namespace.

How does the persona's pool class flow +through? + +- **Matters because:** if Paige's realtime turn needs vision and + vision goes to the background pool, her turn missed its budget. +- **Blocks:** vision-as-crutch integration. +- **Candidates:** + - Pool class propagates through the chain — vision call inherits + Paige's realtime class + - Vision has its own pool independent of caller + - The orchestrating layer (PersonaCognition) explicitly threads + pool class +- **Decision needed by:** vision-crutch implementation. + +#### Q19 — Multi-modal model decomposition + +Native multimodal Qwen (the M5 target) handles vision INSIDE the +LLM forward pass.

If +not, the coordinator must track sequence-by-sequence state +outside the adapter. + +- **Matters because:** the coordinator returns per-handle + responses; if it can't tell which lane finished, batching + breaks down. +- **Blocks:** Step 4 of the realistic-lane build (continuous + batching in LlamaCpp adapter). +- **Candidates:** + - Direct llama.cpp API audit + use what's there + - Wrapper layer that tracks per-sequence state in the adapter + - Single-sequence fallback when batched-decode lacks the data +- **Decision needed by:** before LlamaCpp coordinator wiring. + +#### Q22 — Model-pick policy for the realistic target + +What `model_for_tier(tier)` mapping does the substrate ship for +the realistic floor? + +- **Matters because:** the substrate must pick something + reasonable out of the box on every supported host class — a + CPU-only laptop user shouldn't have to configure anything to + get a usable persona. +- **Blocks:** realistic-lane defaults. +- **Candidates** (draft, Joel decides): + - Apple Silicon UMA ≥ 16 GB: Qwen-2.5-7B Q4_K_M + - Apple Silicon UMA 8–16 GB: Qwen-2.5-3B Q4_K_M + - Mac Intel + Metal ≥ 16 GB: Qwen-2.5-3B Q4_K_M + - CPU-only ≥ 8 GB: Gemma-2-2B Q4_K_M (best creative density at small size) + - CPU-only < 8 GB: heuristic adapter fallback +- **Decision needed by:** before realistic-lane MVP ships. +- **Lives in:** `governor/model_policy.rs` (or similar) + +#### Q23 — KV cache precision switch (FP16 ↔ INT8) + +When KV cache tightens, does the coordinator silently switch to +INT8 KV via `inference/kv_quant.rs` (already in tree)? + +- **Matters because:** this is the adaptive-resolution dial in + miniature. Cheap, big quality preservation, gains ~50% effective + KV capacity. +- **Blocks:** PressureBroker integration for the realistic build. +- **Candidates:** + - Always-on (default INT8 from the start; saves memory by default) + - Pressure-driven (FP16 when comfortable; INT8 under Warning; + INT4 under High) + - Per-lane-class (Pinned lanes stay FP16, Graceful drop to INT8 + under pressure, Hard always INT8) +- **Decision needed by:** PressureBroker integration step. + +#### Q24 — TaskKind change mid-session + +A lane's TaskKind changes during a session (Chat → CodingLarge +when the user pastes a 100-line file). Can the lane upgrade in +place? + +- **Matters because:** if no in-place upgrade, the user closes + + reopens; this is a UX hiccup but tractable. In-place upgrade is + smoother but adds complexity. +- **Blocks:** Step 1 lane API. +- **Candidates:** + - A: Lane is immutable; persona closes + reopens (MVP) + - B: `ai/inference/upgrade-lane { handle, new_task }` command that + re-acquires the lease at the new budget + - C: Coordinator detects need from input length, auto-upgrades +- **Decision needed by:** Step 1 lane API design. Likely A for MVP, + B as a near-follow-up. + +#### Q25 — Idle-lane KV demotion policy + +When a lane goes idle (no requests for N seconds), does the +coordinator preemptively demote KV cache to Warm → Bench tier? + +- **Matters because:** active conversation needs Fast tier KV; + idle lanes hogging Fast tier starve fresh activations.

Discovers the local airc daemon + the scope's default room. +//! 2. Attaches as the demo persona (default `Paige`, configurable +//! via `CONTINUUM_PERSONA`). +//! 3. Joins the default room. +//! 4. Polls airc for new transcript events on every tick (every +//! `CONTINUUM_CHAT_DEMO_POLL_MS` ms; default 3000). +//! 5. For each new chat message NOT from Paige herself: +//! a. Builds a `RagInspectionRequest` for her. +//! b. Calls `inspect_persona_rag_with_inference` — the L1 RAG +//! layer surfaces her recent transcript, the +//! HeuristicInferenceAdapter generates a deterministic +//! response, the result captures the model response. +//! c. Posts the response text back via `airc.say(...)`. +//! 6. Prints the live trace to stdout — what came in, what RAG +//! delivered, what Paige said back. +//! +//! Run from the operator's shell against the live airc daemon: +//! +//! cargo run --bin airc_chat_demo --features metal,accelerate +//! +//! Then in another shell or via the chat widget, send a message to +//! the same room — Paige replies via the heuristic adapter within +//! one poll tick. Stop with Ctrl-C. +//! +//! ### What this proves +//! +//! - The substrate's RAG layer + inference chain + airc round-trip +//! work end-to-end on the operator's actual hardware. +//! - The heuristic adapter ([[inference-is-an-adapter-always-in-the-loop]]) +//! produces a deterministic, observable response without needing +//! a GGUF or cloud key. +//! - Swapping the heuristic adapter for a real LlamaCppAdapter (or +//! AircRemoteInferenceAdapter routing to a grid peer) is a +//! one-line config change — the surrounding code doesn't shift. +//! +//! ### What this is NOT +//! +//! - Not the production persona-cognition path. The substrate's +//! real `PersonaAircRuntime` will wire an inbound pump that +//! triggers `cognition::generate_response` (task #112 refactors +//! it through the handle store). This demo is the proof that +//! the wire shape works end-to-end; production wiring is a +//! focused follow-up. +//! - Not a multi-persona test. ONE persona, ONE room. The +//! coordinator + lane multiplexing tests cover the N-persona +//! case; this demo focuses on the chat round-trip. +//! +//! ### Inbound: subscribe, not poll (RTOS doctrine) +//! +//! v1 of this demo polled `airc.page_recent(N)` every tick to +//! detect new messages. That hid the substrate's actual contract +//! and tripped a false-positive "fanout gap" hypothesis. The +//! reality (confirmed by tracing 2026-06-01): +//! +//! - `Airc::subscribe()` (`crates/airc-lib/src/messaging.rs:204`) +//! ALREADY routes through the daemon's attach stream when +//! daemon-attached. It opens `AttachRequest`, decodes each +//! `Response::Event { envelope }` via `decode_wire_event`, and +//! delivers `Arc` through an `EventStream` — +//! with reconnect-from-cursor on daemon restarts. +//! - `Airc::page_recent()` (when daemon-attached) issues an +//! `InboxRequest` to the daemon which replays the durable +//! tier via `state.router.resume_from_cursor`. So the warm-up +//! high-water mark IS correct. +//! +//! The current shape: page_recent once for the cursor, then loop +//! on subscribe() forever. No polling, no per-tick diagnostics +//! needed — events arrive as they're published. +//! +//! ### Empirical status (2026-06-01) +//! +//! Tested live on Joel's MacBookPro15,1 against the running +//! daemon (build=71a07525f57c, branch=feat/airc-ipc-endpoint-command): +//! +//! 1. Demo starts, attaches as Paige, subscribes via the public +//! `Airc::subscribe()` API — `✓ subscribed to live daemon stream` +//! prints, no error from the attach handshake. +//! 2. Three test messages posted via `airc msg` land in the +//! daemon's `~/.airc/events.sqlite::bus_events` table +//! (verified directly: epoch=124, counters 646-648, +//! matching channel uuid). +//! 3. Demo's `subscribe()` stream yields zero events — no +//! "inbound" log line, no "subscribe stream ended" log line. +//! The mpsc is open but silent. +//! +//! Diagnosis: messages are landing in the bus but the daemon's +//! per-subscriber fanout is NOT pushing them to Paige's IPC +//! attach stream. This is **task #82** ("Headless break #3: CBOR +//! Response::Event schema mismatch") manifesting on the live +//! daemon — either decode_wire_event silently bails (the +//! current daemon_subscribe loop `Err(_) => return` swallows it +//! at airc-lib/src/daemon.rs:416) OR the subscriber filter on +//! the daemon side doesn't match these envelopes. +//! +//!

Inference handle store — establish-once / reuse-many sessions. +//! +//! Joel (2026-05-31): "Maybe you get a handle first then inference? +//! Establish once? Keep loaded or it pages itself intelligently but +//! still a handle. That way you've got a remote handle or a cloud +//! handle. Etc. typically you call these things repeatedly in." +//! +//! ### Why this exists +//! +//! Real inference is rarely one-shot. A persona service cycle, a +//! RAG inspection turn, a sentinel review may issue dozens or +//! hundreds of inference calls in close succession. Every one +//! reloading the model, reopening the cloud connection, or +//! re-routing through airc is wasteful. The session pattern: open +//! once, reuse for many calls. Eventually the substrate's pressure +//! policy evicts cold sessions LRU-style (same shape as +//! [[LORA-GENOME-PAGING]] adapter eviction). +//! +//! ### Library layer +//! +//! This module ships the library piece — `InferenceSession`, +//! `InferenceHandleStore`, and the open/generate/close lifecycle. +//! The ServiceModule wrapper that exposes `ai/inference/open`, +//! `ai/inference/generate`, `ai/inference/close` as commands lives +//! in a follow-up slice. Same staging approach as `rag_inspect`: +//! pure-Rust library first, command surface on top. +//! +//! ### Adapter-agnostic +//! +//! Works uniformly for every AIProviderAdapter — Heuristic, +//! Anthropic, OpenAI-compatible, LlamaCpp, future AircRemote. The +//! session holds whatever per-adapter state matters (system prompt, +//! sampling defaults, LoRA layer config, persona scope); the +//! adapter trait stays unchanged. +//! +//! ### Doctrine alignment +//! +//! - [[inference-is-an-adapter-always-in-the-loop]] — handle pattern +//! is THE canonical inference shape; one-shot generate is a +//! convenience that wraps open+generate+close internally +//! - [[cell-processor-command-runtime]] — HandleRef is the substrate's +//! universal session primitive; reusing it keeps the inference +//! surface compositional with data cursors, generator handles, +//! chat sessions +//! - [[observability-is-half-the-architecture]] — every open/generate +//! /close records timing, generation_count, last_used_ms so +//! mechanic-shop introspection can answer "is this session warm? +//! how often is it generating? when was the last call?" +//! - [[rust-is-the-core-node-is-the-shell]] — handle store lives in +//!

Lane — the unit of inference budget per +//! [[INFERENCE-LANES-REALISTIC.md]]. +//! +//! Joel (2026-05-31): "I think we weren't clever enough with our +//! lanes. The goal should be to ideally cover the needs of the +//! persona, while being realistic." +//! +//! A lane is `(persona, TaskKind, ThroughputLease)` over the shared +//! base model. Multiple lanes share the loaded model bytes; only KV +//! cache + persona-scoped state differs per lane. Continuous +//! batching multiplexes lanes through the same forward pass. +//! +//! This is the substrate's "ONE model, N lanes" cleverness — the +//! prior-attempt failure mode was conceiving lanes as separate +//! model loads. Lanes are recipe-budgeted KV slots, not weight +//! copies. +//! +//! ### Composition (no reinvention) +//! +//! Lane sits at the intersection of pre-shipped primitives: +//! +//! - [`crate::cognition::throughput_lease::ThroughputLease`] — the +//! slot primitive, including the revocation policy (Pinned / +//! Graceful / Hard) that the pressure broker honors. +//! - [`crate::inference::recipe_budget::TaskKind`] — the canonical +//! per-task seed budget table. +//! - [`crate::genome::working_set::PersonaId`] — the substrate's +//! persona identity type. +//! - [`HandleRef`] — the inference handle the caller threads +//! through `ai/inference/{open,generate,close}`. +//! +//! The Lane glues these together. The InferenceCoordinator +//! (`coordinator.rs`, lands next) owns a `DashMap` +//! and decides admission via the existing `AdaptiveThroughputPlanner`. +//! +//! ### Doctrine alignment +//! +//! - [[inference-scarcity-economics]] §"commands are dumb" — Lane is +//! internal substrate state, never visible at the command surface. +//! `ai/inference/open` returns a HandleRef; the Lane is bookkeeping +//! behind it. +//! - [[host-the-seemingly-impossible]] — Lane is the unit through +//! which one model serves 16 personas on commodity hardware.

This is the same +//! polymorphism rails per [[organization-purity-as-we-migrate]] — +//! adapter-first methodology: ship the trait + one heuristic +//! implementation + a stub for tests. +//! +//! ### Why it matters +//! +//! `EngramSource` proves the trait against the in-process engram +//! store. `AircRagSource` proves it against actual airc message +//! data the persona is hosting on the substrate. Together they +//! demonstrate the trait shape composes against multiple real- +//! world backing stores without source changes to either the +//! allocator or the assembly layer. This is the substrate's +//! "every base model includable + every data source pluggable" +//! thesis in code form (per +//!

Per [[RTOS-brain-no-region-on-hot-path]]: the source's `deliver` +//! does its scoring + selection synchronously inside the call. No +//! I/O, no async wait. The expensive work (admission, decay, +//! consolidation) lives in the hippocampus's own tick — this source +//! just reads pre-staged state. +//! +//! Per the no-clipping doctrine +//! ([[docs/architecture/EVERY-MODEL-INCLUDED-VIA-L1-BUDGET.md]]): +//! atomic unit = one engram. Engrams that don't fit are returned +//! via the continuation cursor for a later turn or operator-driven +//! resume. Mid-engram truncation is structurally impossible. +//! +//! Per [[substrate-is-a-good-citizen-on-the-host]]: the metadata +//! field on every emitted `RagItem` carries provenance — engram_id, +//! kind, admitted_at_ms, score — so prompt assembly + sentinel +//! verifiers + future telemetry can trace what made it in. +//! +//! ### Scoring (slice 10 — simplified Algorithm 1+2) +//! +//! score = 0.6 × salience + 0.4 × recency_normalized +//! +//! - **salience** comes from `RecallMetadata.salience` (admission- +//! time default 0.5; decays per Algorithm 4; uplifts on recall +//! hits per slice 5's `record_recall_hit`). Floored at +//! `SALIENCE_FLOOR` from the anti-amnesia work, so engrams never +//! drop to invisible. +//! - **recency_normalized** is linear over 24h: engrams admitted +//! right now score ~1.0, engrams ≥ 24h old score 0.0. +//! +//! Future slices add: +//! - Algorithm 2 channel-bias (`ctx.airc_room` → boost when engram +//! origin matches the current room) +//! - Algorithm 2 structural relevance (engram graph activation +//! spreading from query embedding) +//! - Algorithm 2 topic similarity (vector cosine vs query +//! embedding once embeddings are wired through `RagContext`) +//! - Compressed resolution (engram summary instead of full content) + +use std::sync::Arc; + +use async_trait::async_trait; + +use crate::persona::admission_state::AdmissionState; +use crate::persona::engram::Engram; +use crate::persona::rag_budget::{ + ContinuationCursor, RagContext, RagDelivery, RagItem, RagSource, ResolutionPreference, +}; + +/// 24 hours in ms — the normalization window for the recency +/// score.

RagBudgetManager — flexbox-style token allocation across RAG +//! sources, with the no-clipping doctrine baked in. +//! +//! ### What this module solves +//! +//! Every LLM has a different context window — local Qwen 1.7B at 4k, +//! Qwen 3-30B at 128k, Claude Sonnet at 200k, future models at 1M+. +//! Plus per-channel constraints (video real-time is bandwidth-bound, +//! coding sessions can afford bigger working sets) and per-LoRA-stack +//! overhead. The L1 RAG working memory has to share that budget +//! across multiple content sources (recent conversation, salience- +//! scored engrams, code context, tool descriptions, …) WITHOUT +//! truncating anyone mid-content. Clipping breaks HTML, code, JSON, +//! mid-sentence semantics — it's never acceptable. +//! +//! Per `RAGBudgetManager.ts` (the production TS prior art) + +//! `docs/architecture/COGNITION-CACHE-HIERARCHY.md` (the L1 budget +//! math + recent-universal floor doctrine), this module implements +//! a CSS-flexbox-inspired allocator that gives each source a token +//! budget; sources are responsible for delivering COMPLETE atomic +//! units within that budget. +//! +//! ### Doctrine — no clipping +//! +//! When budget is tight, sources are dropped WHOLE in priority +//! order (required=false first). A source that can't satisfy its +//! `floor_tokens` (the unconditional minimum) returns +//! `AllocationState::UnderProvisioned` and the caller escalates — +//! the substrate never silently clips content mid-unit. +//! +//! The source-owned-unit model means each source decides what +//! counts as "complete": +//! - `ConversationSource`: one message +//! - `EngramSource`: one engram +//! - `CodeSource`: one function / one snippet +//! - `ToolSource`: one tool description +//! The allocator never knows what a "complete unit" looks like — +//! it only deals in token counts. +//! +//! ### Doctrine — sources own state +//! +//! Joel, 2026-05-31: "And to maintain state if necessary." +//! +//! Implementations use interior mutability (DashMap, Mutex, atomics) +//! to hold per-source state — cursor positions, recently-served +//! sets, computation caches, telemetry. The `RagSource::deliver` +//! method takes `&self`; state lives inside via the same pattern +//! `PersonaAircRuntimeRegistry`, `RecallMetadataRegistry`, etc. +//! already use across the substrate. +//! +//! ### Variability is intrinsic +//! +//! Context window sizes vary by 250×. Allocation must scale +//! continuously (no `if context > 32k` branches inside the +//! algorithm). The `RagBudgetAdapter` trait + per-profile presets +//! handle the variability cleanly; the math doesn't care. + +use std::sync::Arc; + +use async_trait::async_trait; +use serde::{Deserialize, Serialize}; + +//============================================================================= +// CONTEXT — Android-style first-parameter pattern +//============================================================================= + +/// Site-wide substrate call context.

RAG turn capture — the mechanic-shop's lift + diagnostic gauges. +//! +//! Per Joel (2026-05-31): "We have often needed to see how a model +//! would work to debug it.

Per memory [[persona-record-replay-is-a-product-requirement]]: +//! capture live turns + replay; AR/CV source-video pattern; infra +//! (LiveTurnReplayFixture) exists but unwired — this slice wires +//! capture for the RAG layer specifically. +//! +//! ### What this module provides (slice 11 — capture side) +//! +//! - `RagCaptureEvent` — a tagged record of one fact in the turn +//! (TurnStart, BudgetAllocated, SourceDelivered, TurnEnd). +//! - `RagCaptureSink` trait — abstract recording surface. +//! - `NoopRagCaptureSink` — production-safe default. Drops events on +//! the floor; zero overhead when capture isn't in use. +//! - `JsonlRagCaptureSink` — file-based JSON-line writer. One JSON +//! object per line; replay reader groups by turn_id. +//! - `RecordingRagSource` — decorator wrapping any `RagSource`, +//! intercepts `deliver` and `deliver_continuation`, records the +//! call + result via the sink, returns the delivery unchanged. +//! Drop-in around production sources. +//! +//! ### What's deferred +//! +//! - `ReplayRagSource` (slice 11.5) — reads captured deliveries +//! from a sink, returns them instead of hitting live state. +//! Symmetric to RecordingRagSource. +//! - Telemetry counter aggregation across captured events (slice 12). +//! - `airc rag-inspect ` operator CLI (slice 12). +//! - Disk-pressure integration via the substrate pressure broker +//! (task #88). +//! - File rotation policy. JsonlRagCaptureSink takes a path; the +//! caller decides rotation (per-turn file, per-day file, etc.). +//! Capture writes accumulate; source/drain doctrine says they +//! must drain — that policy lives in the caller for slice 11. +//! +//! ### Doctrine alignment +//! +//! - [[substrate-is-a-good-citizen-on-the-host]]: NoopRagCaptureSink +//! is the default; capture is opt-in. Atomic appends within- +//! process via Mutex. Honest observability — every event +//! carries persona_id + turn_id (when present) for cross-event +//! correlation. +//! - [[RTOS-brain-no-region-on-hot-path]]: capture writes are +//! synchronous-after the source's call returns. Off the cognition +//! hot path because cognition is whatever runs INSIDE the +//! source's deliver(); capture writes happen after the cognition +//! work is done. +//! - [[organization-purity-as-we-migrate]]: no backwards-compat +//! hooks.

RecallMetadata sidecar — Algorithm 4's volatile per-engram state. +//! +//! ### Why a sidecar, not Engram fields +//! +//! Per `engram_graph.rs:136-138`'s design note + the +//! [[organization-purity-as-we-migrate]] doctrine: `Engram` is the +//! DURABLE CONTENT layer (id + kind + content + origin + admission +//! provenance). `RecallMetadata` is the VOLATILE RECALL STATE layer +//! (salience + access counts + decay timing + novelty protection). +//! They have DIFFERENT update cadences (Engram is write-once at +//! admission; RecallMetadata is written every recall hit, every +//! decay tick) and DIFFERENT persistence policies (Engram persists +//! eventually to longterm.db; RecallMetadata's L3 persistence is a +//! separate concern with its own coalescing/batching). +//! +//! Keeping them separate lets each evolve cleanly. Per CBAR's +//! event-driven separation of concerns: each layer is its own +//! subscriber/emitter with its own tick. +//! +//! ### Concurrency +//! +//! `DashMap` for lock-free reads on the +//! cognition hot path per [[RTOS-brain-no-region-on-hot-path]] +//! doctrine. Recall scoring (Algorithm 1+2) reads metadata for +//! every candidate engram; this MUST NOT serialize. Per-key writes +//! happen on: +//! +//! - Engram admission (initial salience + protection window write) +//! - Recall hits (access_count++, last_accessed update, salience +//! uplift) +//! - Decay tick (salience-modulated half-life applied per the +//! Algorithm 4 formula) +//! +//! All writes use `DashMap::entry` for atomic compare-update. +//! +//! ### What this module is NOT +//! +//! - NOT the recall scorer. Algorithm 1+2 scoring lives in a +//! sibling module that READS RecallMetadata fields. This module +//! exposes the data + atomic update operations only. +//! - NOT the decay tick. The actual periodic decay sweep runs in +//! the hippocampus's sleep-policy region (per +//! `BRAIN-REGIONS-SUBSTRATE.md`); this module exposes the +//! `apply_decay` operation that the tick calls. +//! - NOT the persistence layer. L2-resident metadata may flush +//! periodically to L3 longterm.db; that lives in a later slice's +//! `RecallMetadataPersistenceModule` (event-driven, dormant-by- +//! default, per the doctrines). +//! +//! ### Field semantics (per `COGNITION-ALGORITHMS.md` Algorithm 4) +//! +//! - `salience: f32` in `[0.0, 1.0]` — Algorithm 4's salience score. +//! 1.0 = "user marked this as important + cross-referenced +//! heavily"; 0.0 = "barely admitted, no rehearsal." Decay +//! half-life scales with `(1.0 + salience)^2` so high-salience +//! engrams decay 4–9× slower than baseline. +//! - `access_count: u32` — Hebbian rehearsal counter. Incremented +//! each time the engram is surfaced in recall AND consumed by +//! the persona's response. "Use it or lose it." +//! - `last_accessed_ms: u64` — wallclock ms of most recent recall +//! hit. Recency input to scoring + decay. +//! - `protected_until_ms: u64` — novelty protection window. While +//! `now_ms < protected_until_ms`, `apply_decay` is a no-op. +//! This implements the [[cognition-cache-hierarchy]] one-shot- +//! protection rule (high embedding-distance outliers get a +//! grace window to prove worth before they're forgotten). + +use std::sync::Arc; +use std::time::{SystemTime, UNIX_EPOCH}; + +use dashmap::DashMap; +use uuid::Uuid; + +/// Per-engram volatile recall state.
