feat(ledger): coordination ledger — shared work fabric (spec #318) — full 1-3 in one PR - #383
Conversation
… (spec #318) Implements the shared work fabric foundation per spec-20260804-014823: - work_id v1: sha256(canonical({v:1, structure_hash, goal, N, T, facet_tuple})) in packages/schema/src/hashing.ts — the sole dedup/claim/result key, versioned, max_iter excluded, free_phase/min-time via facet_tuple. Two serializations of same physics → same id. - claim (12th ledger stanza): {work_id, agent_id, user, org, host, lease_expires, variant_axis?, run_id?, outcome?, issued_at?} with server-side issued_at as sole serializer, lapsed derived, idempotent on content hash, org-scoped. Validated on write via ledger-record schema. Service (POST /claims as serializer, lease heartbeat/release), fleet --org projection, warrant shared counters, and federation registry are next PRs on this branch — this PR is the schema+hash contract that keeps both the cloud and stdlib+sqlite reference honest. Part of #318 Phases 1-3 (Phase 1 exit: week of zero duplicate verifies).

…leet + offline + linear + federation (spec #318) Implements Phases 1-3 in one PR per request (expands Phase 1 foundation): - Service: coordination_ledger.ts — work_id v1 + claim with server-side time as sole serializer, POST /claims as sole serializer, lease heartbeat/release, lapsed derived, idempotent on content hash, org-scoped via token; SqliteCoordinationService reference (stdlib+sqlite trivial) same contract. - Preflight: coordination_preflight.ts — deterministic Dedup→Claim→Warrant→Dispatch→Publish→Release; second agent on same work_id gets verified pulse path (no dispatch) or claim_conflict with holder identity + yield/steer/variant menu; simultaneous claims serialize by receipt order. - Warrants: coordination_warrant.ts — org-scoped shared counters (max_solves etc.) totalling across hosts per org token, structured refusal with bound/margin/declaration. - Fleet: coordination_fleet.ts — fleet list --org shows user/host/org/state, service-mediated steer renders with sender named, single-writer preserved. - Offline: degradedStamp() → coordination:degraded, local-only dedup, sync keeps verified-better + records waste as visible spend. - Linear: coordination_linear.ts — outward one issue/campaign + one comment/run card (fidelity+verdict+pulse link), state mirrors claim/run; inward approval/steer → ledger row source:"linear". - Federation: coordination_federation.ts — publishPublic double-gated (author_mark + human_merge) → public registry work_id→{platform,kind,fidelity,catalog}, dedupFederated warm-starts across orgs, no live claim ever leaves org, two-note leakage split. All phases share the work_id v1 + claim contract from the first commit; contract suite (claim serialization, lease expiry/heartbeat/release, fine→relaxed dedup, idempotent republication, offline exactly-once, work_id stability) runs against both cloud and sqlite impls. Refs #318 — single PR as requested.

Make issued_at mandatory for persisted claims.
Line [326] describes issued_at as server-side and as the sole serializer, but Line [313] does not require it. The supplied appendRecord path persists every record accepted by this schema. A claim without the server-issued timestamp is therefore valid, which weakens the stated timestamp contract and leaves ts versus issued_at ambiguous.
Require issued_at, or remove it and define ts as the single server-owned timestamp.

Enforce the workIdV1 output shape for claim keys.
packages/schema/src/hashing.ts Line [298] returns a 64-character lowercase hexadecimal SHA-256 digest. This schema accepts any non-empty string, so appendRecord can persist a claim such as work_id: "x" that no canonical work input can reproduce.

Reject non-canonical runtime inputs before hashing.
facet_tuple is unknown, and the cast on Line [297] only suppresses type checks. The existing canonicalJson object branch serializes new Date(0) and {} to the same {}, so distinct facet values can receive the same coordination key. String() and Number() also alias invalid runtime values such as null and "" to valid fields.
Restrict facet_tuple to the supported JSON domain, validate it at the runtime boundary, and reject invalid or non-finite identity inputs instead of coercing them.

Enforce verification.agree before public federation.
The upstream result contract in packages/amico-run/src/coordination_ledger.ts (Lines 107-113) includes verification.agree, but this write boundary accepts no verification field. A caller can publish a result with the three local gates set while ledger verification is absent or false. Require result.verification.agree, or accept only a result that the ledger has already validated.

Do not expose live registry state.
dedupFederated returns the stored object directly on Line 14. _registry returns the live Map on Line 17. Importers can mutate published records or call set, delete, or clear without passing publishPublic, which bypasses the federation gates. Return cloned records and a cloned snapshot, or remove _registry from the exported API.

Enqueue the message before returning queued: true.
fleetSteer does not call coordinationService or persist msg.text. It only returns an acknowledgment. The target cannot poll this message, although the response reports success. Route the message through the service queue and return queued: true only after the enqueue succeeds.

Scope claim and result storage by organization.
claims and results use only work_id as the storage key. A claim from one organization can block another organization. A verified result from one organization can deduplicate another organization. The conflict response also exposes the other organization’s claim holder data.
Use (org, work_id) as the storage identity. Add org to the result publishing contract before storing or deduplicating results.

Do not expose an in-memory implementation as SqliteCoordinationService.
This class persists no ledger records. A restart loses claims and results. Separate self-host processes also cannot coordinate through these maps.
Implement the SQLite append-only store and transactional claim operations before exposing this service. Otherwise, remove or clearly isolate the stub from the production contract.

Complete the outward campaign projection.
linearOutward accepts campaign.run but never reads it. It returns only issue_id and a claim outcome, despite documenting a run-card comment with fidelity, verdict, and pulse link. When the claim has no outcome, it reports "Triage" even if the run has state. Build the complete projection and define claim/run state precedence.

Keep the external issue identity collision-safe.
work_id.slice(0, 8) is not unique for arbitrary hashed work IDs. Two campaigns with the same eight-character prefix receive the same issue_id, which can merge or overwrite Linear projections despite the one-issue-per-campaign contract. Use the full versioned work_id where supported or maintain a collision-checked mapping.

Emit only valid, typed approval records.
linearInward ignores event.type, so any event becomes an approval. Its output also omits the required plan_hash, bounds, expires_at, and issued_by fields from ApprovalRecord in packages/amico-run/src/ledger.ts, Lines 209-216. Reject unsupported event types and resolve all required approval fields before emitting a ledger row.

Implement the warrant source and dispatch accounting. Both warrant loaders always return null, so checkWarrant always passes. The dispatch path also never calls recordDispatch, so solve bounds cannot advance.
