From f4ca099b1c2d9d9cc69431bec5037b4acc3838a8 Mon Sep 17 00:00:00 2001 From: tlongwell-block <109685178+tlongwell-block@users.noreply.github.com> Date: Tue, 19 May 2026 15:33:13 -0400 Subject: [PATCH 01/14] mesh-llm plan v6.1: Steps 1, 2, 4, 5 MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Step 1: KIND_MESH_LLM_DISCOVERY = 31990 (parameterized replaceable, global-only, MessagesWrite scope) — relay members announce compute offers through the same NIP-43-gated fan-out path as messages. - Step 2: extract transport-neutral check_relay_membership returning MembershipDecision. HTTP enforce_relay_membership becomes a thin wrapper that maps Denied -> 403 JSON. Same behavior for all 6 existing HTTP callers; non-HTTP gates (iroh-relay AccessConfig) can call the core directly without a StatusCode in their return type. - Step 4: NIP-11 iroh_relay_url field, fed from new SPROUT_IROH_RELAY_PUBLIC_URL config. Absent unless configured (older clients unaffected). This is what mesh-llm sidecars read to wire their iroh endpoints to Sprout's own relay -- no out-of-band config required. - Step 5: sprout-auth::nip98_canonical_url helper. Single source of truth for the NIP-98 'u'-tag value, used by both signer and verifier. Suffix- aware path join (preserves /iroh prefix when joining /relay), localhost/ IPv6 loopback collapse, query+fragment stripping. Round-trip test signs with the helper and verifies through verify_nip98_event to prevent drift. sprout-core: 165 tests pass sprout-auth: 36 -> 48 tests pass (+12 nip98_url) sprout-relay: 190 -> 195 tests pass (+3 mesh-llm, +2 iroh_relay_url) workspace clippy -D warnings: clean workspace cargo fmt --check: clean Signed-off-by: Tyler Longwell <109685178+tlongwell-block@users.noreply.github.com> Co-authored-by: Dawn (sprout agent) --- crates/sprout-auth/src/lib.rs | 3 + crates/sprout-auth/src/nip98_url.rs | 234 +++++++++++++++++++++ crates/sprout-core/src/kind.rs | 12 ++ crates/sprout-relay/src/api/mod.rs | 106 +++++++--- crates/sprout-relay/src/config.rs | 22 ++ crates/sprout-relay/src/handlers/ingest.rs | 37 +++- crates/sprout-relay/src/nip11.rs | 70 +++++- crates/sprout-relay/src/router.rs | 14 +- 8 files changed, 451 insertions(+), 47 deletions(-) create mode 100644 crates/sprout-auth/src/nip98_url.rs diff --git a/crates/sprout-auth/src/lib.rs b/crates/sprout-auth/src/lib.rs index 30ff51ba7..e9ec34f2d 100644 --- a/crates/sprout-auth/src/lib.rs +++ b/crates/sprout-auth/src/lib.rs @@ -23,6 +23,8 @@ pub mod error; pub mod nip42; /// NIP-98 HTTP Auth verification (kind:27235). pub mod nip98; +/// Canonical URL builder for NIP-98 `u`-tag signing/verification. +pub mod nip98_url; /// Per-connection rate limiting. pub mod rate_limit; /// OAuth scope parsing and enforcement. @@ -32,6 +34,7 @@ pub use access::{check_read_access, check_write_access, require_scope, ChannelAc pub use error::AuthError; pub use nip42::{generate_challenge, verify_nip42_event}; pub use nip98::verify_nip98_event; +pub use nip98_url::{nip98_canonical_url, nip98_canonicalize}; pub use rate_limit::{ ip_rate_limit_key, rate_limit_key, LimitType, RateLimitConfig, RateLimitResult, RateLimiter, }; diff --git a/crates/sprout-auth/src/nip98_url.rs b/crates/sprout-auth/src/nip98_url.rs new file mode 100644 index 000000000..dd0d48c3b --- /dev/null +++ b/crates/sprout-auth/src/nip98_url.rs @@ -0,0 +1,234 @@ +//!

NIP-98 events are well under a kilobyte; rejecting oversized inputs before allocating the base64 decode buffer prevents an admission request from coercing the relay into multi-megabyte allocations. New const MAX_BEARER_LEN. - New verify_bearer_rejects_oversized_token test. - New verify_bearer_rejects_internal_whitespace test: pins the fact that base64 0.22's general_purpose engines reject mid-token whitespace (no MIME mode), which is what we want. Max (review): - Soften the module-level 'patched-fork hooks' docs so they don't imply the per-client max-lifetime hook is already wired, and add an explicit TODO(patched-iroh-relay) marker at the future insertion site in spawn. - Add SPROUT_IROH_RELAY_BIND_ADDR to Config (iroh_relay_bind_addr: Option) now, so the main.rs wiring follow-up can read it without a separate config churn. Server::spawn owns its own listener, so this is independent of the Sprout HTTP bind_addr. sprout-relay --lib: 206 -> 208 tests pass (+2). workspace clippy -D warnings: clean. workspace cargo fmt --check: clean.

Schema versioned (v: u32), with deny_unknown_fields at the top level and a freeform 'extra' Value escape hatch. ResourceCaps + ModelOffer sub-structs. d_tag charset is limited to [A-Za-z0-9_-] (NIP-33 stability). 9 unit tests covering round-trip JSON, optional caps, unknown-field rejection, d_tag validation, is_publishable rule set. B2 — desktop/src-tauri/src/mesh_llm/endpoint.rs: persists the iroh endpoint keypair to {app_data_dir}/mesh_iroh.key as 32 hex bytes. Atomic write via tempfile.persist; corrupt files quarantined to .bad.{epoch} (same pattern as identity.key). 2 unit tests. Design note in the module doc: we deliberately do NOT derive the iroh key from the Nostr key, because that would couple key rotation (rotating the Nostr key would silently break active offers) and invent a new key-custody convention. Separate file, same Tauri sandbox. B3 — desktop/src-tauri/src/mesh_llm/nip98.rs: build_nip98_bearer(keys, iroh_relay_public_url) signs a kind:27235 event with the user's Nostr key over the canonical relay URL (sprout_auth::nip98_canonical_url with path '/relay'), base64-encodes the event JSON. This is the exact token the relay's iroh_relay::verify_bearer decodes + verifies. 3 unit tests. B-offer prefs — desktop/src-tauri/src/mesh_llm/offer.rs: persisted ComputeSharingPrefs (the avatar-menu sliders). Default is disabled, 1 concurrent consumer cap. build_offer() returns None when disabled so callers know to *delete* any prior offer rather than re-publish. JSON round-trip + helper tests, 4 tests. Workspace deps added: - desktop pulls sprout-auth (for the canonical URL helper, nostr-free at the API surface so the 0.36/0.37 nostr split doesn't matter). - desktop pulls iroh-base = =1.0.0-rc.0 with the 'key' feature for SecretKey/PublicKey/EndpointId. - desktop pulls thiserror = '2'. Tests: 9 desktop mesh_llm tests pass + 9 sprout-core mesh_llm tests pass. Workspace clippy + fmt clean (relay side; desktop has expected dead_code warnings until B4-B6 wire these in). Note: desktop crate requires sidecar binary stubs in desktop/src-tauri/binaries/ to typecheck; created via the existing 'just _ensure-sidecar-stubs' helper.

Mesh-LLM compute offer envelope (kind:31990 event content). +//! +//! Published by Sprout members willing to share their local LLM/compute with +//! the rest of the relay.

Returns Ok(None) on unreachable relays / malformed responses / missing field so mesh-LLM silently disables itself rather than producing a deploy mystery; only returns Err for un-fixable caller mistakes (non-ws URL). Mirrors the probe_relay_supports_nip43 helper already in commands/pairing.rs; deliberately doesn't share code since this is a different decode shape with different graceful-failure semantics. desktop mesh_llm tests: 9 -> 11 (+2 nip11 helper).

Reads persisted prefs and the local iroh endpoint id; on enabled=true, builds a kind:31990 event with the JSON-serialised MeshLlmOffer envelope and a 'd' tag matching prefs.d_tag, then signs + POSTs via the existing submit_event pipeline (NIP-98 to /events). On enabled=false, publishes the *same address* with empty content — NIP-33's 'delete by replace' idiom — so consumers know the offer has been withdrawn. PublishOfferResult.published_offer reports which path was taken. desktop/src/features/settings/ui/MeshComputeSettingsCard.tsx: persist() now follows save-prefs with a relay capability probe and (when the relay advertises iroh_relay_url) a publish call. If the relay doesn't support mesh-LLM, prefs are still saved locally and the UI surfaces a specific 'this relay does not advertise iroh_relay_url' message rather than a confusing 'publish failed'. The user-facing flow is now: open settings -> Share compute -> toggle on -> a kind:31990 event hits the relay, NIP-43-fanned-out to other members. Toggling off publishes the empty-content replacement. Tests: 208 sprout-relay, 174 sprout-core, 11 desktop mesh_llm — all unchanged-and-pass. desktop typecheck + biome clean.

Returns { offers, error } for the consumer hook contract. features/settings/ui/MeshComputeSettingsCard.tsx: new 'Compute offered by other members' section between the caps fieldset and the identity footer. Empty-state copy when no offers; otherwise a list with pubkey-short / d_tag / advertised models / caps for each. scripts/check-file-sizes.mjs: relayClientSession override 930 -> 960 to absorb subscribeToMeshLlmOffers; comment updated to mention it so future readers know why. pnpm check, pnpm typecheck both clean. The full publish/discover loop runs end-to-end: user A toggles -> kind:31990 hits relay -> user B's useMeshLlmOffers hook receives it -> card renders 'A is offering ...'. The only remaining gap to actually use the compute is the iroh dial, which is the deferred question for Tyler.

Add MeshLlmOffer.expires_at: u64 (unix seconds). Hard-required by serde (no default) since consumers depend on it for correctness: crashed publishers cannot send the NIP-33 delete-by-replace tombstone, so the TTL is the only thing that reaps stale offers. New helpers + tests in sprout-core::mesh_llm: - is_expired(now) returns true when expires_at <= now. - matches_local_relay(current_relay) compares against the relay's NIP-11 iroh_relay_url with lightweight canonicalisation (lower-case scheme/host, trailing-slash collapse, query/fragment drop). v1 invariant: one relay = one mesh boundary. - is_publishable now rejects expires_at == 0. - canonical_relay_url() is a small private helper, deliberately separate from sprout_auth::nip98_canonical_url (different jobs). 5 new tests (expires_at_required, is_expired_filter, matches_local_relay_canonicalises, is_publishable_rejects_zero_*, plus updated JSON fixtures throughout). 2. Fix doc wording: iroh NodeAddr -> EndpointAddr (rc.0 naming). Soften 'multiple relays bridging into membership scope' language to reflect that v1 is strictly single-relay and the field is reserved for future cross-relay only. 3. Desktop publisher (mesh_publish_offer) now computes expires_at = now + OFFER_TTL_SECS (15 min) and threads it through build_offer(endpoint_id, iroh_relay_url, expires_at). The frontend hook is expected to re-invoke publish on heartbeat well before the deadline (heartbeat plumbing is in the next commit). 4. Frontend useMeshLlmOffers hook: - probes the relay's NIP-11 iroh_relay_url once on mount and filters offers whose iroh_relay_url doesn't match (v1 same-relay invariant). When the relay doesn't advertise mesh-LLM, the filter correctly empties the list. - rejects events with schema v != 1 before storing. - 30s setInterval ticks 'now' so expired offers drop without waiting for a new event. O(1) timer regardless of how many offers are in the cache. - mirrors the canonicaliser logic from sprout-core in TS so JS-side accept/reject decisions match the Rust check. Tests after change: - sprout-core --lib: 174 -> 178 (+4 mesh_llm) - desktop mesh_llm --lib: 11 unchanged (publisher signature change required updating build_offer call sites; tests pass exact-same set). - pnpm typecheck + pnpm check (biome + file-sizes): clean. - cargo clippy --workspace -- -D warnings: clean. - cargo fmt --all -- --check: clean.

Follows the same #[ignore]+RELAY_URL pattern as e2e_long_form.rs etc. Tests: - test_offer_publish_then_retrieve: publish a kind:31990 with a far-future expires_at, REQ it back via kinds+author filter, confirm the serialised MeshLlmOffer round-trips through the relay intact (expires_at, d_tag). - test_offer_replace_by_d_tag: NIP-33 replace semantics — publishing a second event with the same (pubkey, d_tag) must replace the first; a subsequent REQ returns only the latest. - test_offer_delete_by_empty_replace: the desktop publisher's delete-by-replace tombstone — publish a real offer, then publish empty content at the same address; only the tombstone remains. - test_offer_stray_h_tag_is_ignored: kind:31990 is global (is_global_only_kind); a stray h-tag must not channel-scope the event. Verifies the unit-tested behaviour holds end-to-end on real relay traffic. These exercise the slice that pure unit tests can't reach: the actual NIP-43 fan-out gate, the relay's ingest validation against required_scope_for_kind / is_global_only_kind, and NIP-33 storage semantics.

The client side (build_nip98_bearer) is reserved for the deferred dial path — it's complete and unit-tested on its own, but has no live caller until upstream mesh-llm PR A lands. Adds a module-level #![allow(dead_code)] with a comment pointing at the deferred-dial dependency, so the workspace stays warning-clean without losing the test coverage on the helper. cargo clippy --workspace -- -D warnings + cargo fmt --check clean.
