T5.3 — kt_sync_to_linear (real Linear GraphQL sync)

Implements the last sync stub. Mirrors the shipped T5.2 GitHub design; no new migration (the track_external_links table and tracks.last_linear_sync_at already generalize).

Design (frontier panel 2026-09-19, unanimous auto_lookup_with_config_override)

  • GraphQL client (src/linear/linear-client.ts): raw fetch, no SDK; Authorization: <key> (no Bearer); 200-with-errors treated as failure; ambiguous flag so a create that may have landed keeps its pending link.
  • Workflow-state resolver (src/mcp/tools/linear-payload.ts): a done track's issue moves to a completed state (team's lowest-position, or optional done_state_id); a non-done track's issue is never auto-moved backward unless a valid open_state_id is configured and the issue is currently completed/canceled. Two optional fields added to the Linear adapter config.
  • Service (src/mcp/tools/sync-to-linear.ts): same durable pending creation-intent, marker crash-recovery (adopt-only, never auto-recreate), and {ok:false, error} envelope as GitHub. Prefixes: LINEAR_AUTH_FAILED / NOT_FOUND / RATE_LIMITED / TIMEOUT / STATE_CONFIG / UNKNOWN_ERROR.
  • kt_get_track exposes linear_issue_url (parity with github_issue_url).

Tests

Offline only (fake LinearClient, no network in CI): 51 new tests — payload+resolver units, GraphQL client units, and integration (create/update/no-op, done→completed state, override, tie-break, no-completed-state, team-changed, concurrency→one create, crash-recovery adopt, marker-miss no-recreate). Full suite green locally except a pre-existing Windows-only temp-dir flake in load-dotenv.test.ts (passes on Linux CI).

Deliberate v1 bounds (documented, not hidden)

  • Same as T5.2: no retries/backoff, no update-path lock, no auto-recreate on a stale link.
  • Non-done tracks are never auto-moved backward (the panel's item-2 safety rule takes precedence over item-15's "default unstarted"), to avoid clobbering an issue a user moved to In Progress.
  • Real-workspace dogfood is the one remaining acceptance gate (mirrors T5.2's real-repo gate).

Summary by CodeRabbit

  • New Features

    • Linear synchronization now creates and updates issues without duplicates.
    • Unchanged content is skipped, while interrupted operations can recover safely.
    • Track details now include the linked Linear issue URL.
    • Open and completed workflow states can be configured.
    • Sync results provide actionable rate-limit, configuration, and connection errors.
  • Bug Fixes

    • Improved handling of concurrent syncs, failed requests, and team changes.
    • Prevented duplicate issue creation after ambiguous failures.
    • Refreshed linked issue URLs when synchronized content changes.

Mirrors the shipped T5.2 GitHub sync: track_external_links is the
authoritative idempotency key, a durable 'pending' creation-intent is
committed before the outbound mutation, crash recovery adopts via the
hidden marker and never auto-recreates, and the client is injectable so
CI never calls Linear. No new migration — the T5.2 table and
tracks.last_linear_sync_at already generalize.

Linear-specific (frontier panel 2026-09-19, unanimous
auto_lookup_with_config_override):
- GraphQL client (raw fetch, no SDK; Authorization: <key>, no Bearer;
  200-with-errors handled; ambiguous flag for create safety).
- Workflow-state resolver: a done track's issue moves to a completed
  state (team's lowest-position completed, or optional done_state_id);
  a non-done track's issue is never moved backward unless a valid
  open_state_id is configured. Two optional adapter-config fields added.
- Error prefixes LINEAR_AUTH_FAILED / NOT_FOUND / RATE_LIMITED / TIMEOUT
  / STATE_CONFIG / UNKNOWN_ERROR; kt_get_track exposes linear_issue_url.

Removes the now-dead sync-shared stub. Offline unit + integration tests
(fake LinearClient, no network). Docs: ROADMAP T5.3 + PRD 4.14 updated.

📝 Walkthrough

Walkthrough

The Linear sync stub is replaced with idempotent issue creation and updates, durable recovery, workflow-state mapping, operational error handling, linked issue URLs, and sync watermark updates. Payload, client, integration, unit, and documentation coverage is added.

Changes

Linear synchronization

Layer / File(s) Summary
Payload and state contracts
src/mcp/tools/linear-payload.ts, src/mcp/tools/issue-payload.ts, src/schemas/tools.ts, src/mcp/tools/register-project.ts, tests/unit/linear-payload.test.ts, tests/unit/register-project-schema.test.ts
Linear payloads, hashes, recovery markers, state intent, and workflow-state resolution are implemented. Optional workflow-state overrides are validated, trimmed, stored, and tested.
Linear GraphQL client
src/linear/linear-client.ts, tests/unit/linear-client.test.ts
A native-fetch client performs authenticated issue mutations, marker lookups, workflow-state queries, timeout handling, response validation, and fixed error classification.
Durable synchronization and track exposure
src/mcp/tools/sync-to-linear.ts, src/db/queries/track-external-links.ts, src/db/queries/tracks.ts, src/mcp/tools/get-track.ts, src/mcp/tools/sync-shared.ts, tests/integration/sync-to-linear.test.ts
The sync service validates configuration, manages pending and linked external rows, performs idempotent create/update and recovery flows, updates the watermark, and returns the Linear issue URL. The former sync stub module is removed.
Product and architecture documentation
README.md, docs/PRD.md, docs/ROADMAP.md, docs/TEST_CASES.md, docs/TRD.md
Documentation records implemented Linear synchronization, workflow-state configuration, operational errors, track URLs, timestamps, credential handling, and the remaining real-workspace dogfood gate.

🟡 Minor · Update the stale Adapter glossary entry. · PRD.md:555

docs/PRD.md:555
📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Update the stale Adapter glossary entry.

Line 555 still states that kt_sync_to_linear ships only its precondition stub and that its outward push is deferred to T5.3. Section 4.14 now documents the implemented sync. Align the glossary with §4.14.

✏️ Proposed wording
-`kt_sync_to_github` (§4.13) is implemented (T5.2 — a real one-way, per-track push that creates/updates the linked Issue idempotently); `kt_sync_to_linear` (§4.14) still ships only its precondition stub (project/track validation plus a `CONFLICT` when no adapter is configured), with its outward push deferred to T5.3.
+`kt_sync_to_github` (§4.13, T5.2) and `kt_sync_to_linear` (§4.14, T5.3) are both implemented — a real one-way, per-track push that creates/updates the linked Issue idempotently.

- linear-client: keep 5xx ambiguous even with Retry-After (P1 — was
  reclassified as a definitive rate-limit, risking a duplicate on the
  next create); treat a mutation's opaque GraphQL errors array as
  ambiguous (P1 — may have committed); treat an explicit success:false
  mutation payload as definitive so the pending claim clears cleanly.
- linear-payload: fold configured done_state_id/open_state_id into the
  no-op content hash so re-registering with a different override
  re-syncs instead of a false no-op.
- sync-to-linear: refresh the stored external_url on update (a Linear
  URL can change while the issue id is stable).
- track-external-links: updateLinkedContentHash optionally refreshes
  external_url (GitHub call unchanged).
- docs: README / TEST_CASES / TRD now describe the shipped Linear sync
  (no longer a stub) incl. LINEAR_RATE_LIMITED / LINEAR_STATE_CONFIG.
- +5 regression tests (56 Linear tests green).

- docs: remove the remaining stub-era Linear passages (PRD SYNC_DRIFT row, Adapter glossary, Track data-model row) and fix the TRD source-tree note (drop the deleted sync-shared.ts reference and the 'until T5 starts' claim).

- sync-to-linear: resolve the Linear workflow state BEFORE committing the durable pending claim, so a crash during that (Linear-only) network read can't wedge a pending row for a create that was never attempted; the claim (ON CONFLICT DO NOTHING) still commits before the outbound mutation.
- sync-to-linear: validate a configured done_state_id/open_state_id eagerly (even on a non-done track) so a misconfigured override surfaces as LINEAR_STATE_CONFIG up front instead of only when the track later becomes done.
- docs: reconcile the remaining stub-era passages — TRD 5.3 credential-access paragraph (sync path is implemented; clients under src/github, src/linear); and add github_issue_url/linear_issue_url to the kt_get_track output contract in PRD 4.4 and TRD 3.5.
- +1 regression test (58 Linear tests green).

🟡 Minor · Refresh the Linear URL on the no-op path. · sync-to-linear.ts:161-187

src/mcp/tools/sync-to-linear.ts:161-187
🗄️ Data Integrity & Integration | 🟡 Minor | ⚡ Quick win

Refresh the Linear URL on the no-op path.

When content_hash === hash, the sync returns through okSynced without calling updateExisting. okSynced only updates the sync watermark. Since kt_get_track reads the stored external_url, a Linear team-key or workspace-slug change can leave it stale until the content changes.

Either refresh and persist the current URL on this path, or document that URL refresh requires a content change.

- B1 (duplicate risk): a GraphQL-layer error on a MUTATION no longer downgrades ambiguity by message category. A GraphQL 200-with-errors means the request was accepted and (partially) executed, and the spec allows execution errors after a side effect — so auth/rate-limit/not-found messages on a create are now ambiguous:true (pending kept for marker recovery), not a false 'definitely no write' clear that could let a retry duplicate. Reads stay non-ambiguous.
- B2 (credential hygiene): redact the api_key from every error string the client returns (HTTP body, GraphQL message, and thrown-exception paths), so a key echoed by an upstream body or a native-fetch exception never reaches tool output. Truncation is not redaction.
- +5 regression tests (ambiguity-by-operation, read vs mutation, credential redaction for body + exception).

Adversarial panel: Gemini release_ready(10); GPT-6 fix_then_release(0.97) raised B1/B2 (fixed here) + a no-op revalidation edge (B3) assessed non-blocking — a no-op pushes nothing, so an externally-deleted state surfaces on the next real sync.

- linear-client: redact the api_key from the FULL upstream text BEFORE
  truncating to 300 chars, so a boundary-straddling secret can't survive
  as an unmatched partial (Codex 4054731793).
- linear-client: keep pre-execution GraphQL rejections DEFINITIVE
  (auth / rate-limit / entity-not-found -> ambiguous:false); only a
  generic opaque mutation error stays ambiguous (ambiguous:isMutation),
  reconciling the GPT-6 adversarial pass with Codex 4054731794 -- a wedged
  pending claim after an expired-then-rotated key is worse than the
  opaque-error case.
- linear-payload: reject a 'completed' open_state_id as well as 'canceled'
  (both terminal) with LINEAR_STATE_CONFIG (Codex 4054731797); schema
  comment updated to "non-terminal (backlog/unstarted/started)".
- docs: align the Linear source_ref contract across PRD inputs, PRD
  glossary and TRD schema -- source_ref is the Linear project identity;
  the team issues sync into is adapters.linear.team_id, separate
  (CodeRabbit 4054671748).

Tests: reconciled linear-client ambiguity cases + boundary-redaction
test; added a completed-open-state rejection test. Full suite green
(366 tests); typecheck/lint/prettier/roadmap-drift clean.

PRD inputs table said "Repo URL"; the code stores source_ref unchanged and the
GitHub adapter passes it straight to /repos/{source_ref}/issues, so a repo URL
is an invalid API path — and since source_ref is part of the (source_type,
source_ref) upsert key, a URL vs owner/repo register as different projects.
Documents the owner/repo contract, matching the TRD schema and the code.

Reverses the round-5 "pre-execution definitive" classification for the
HTTP-200 GraphQL-errors path. A 200 response can carry partial data plus
top-level errors, and a text match over the message cannot prove the
mutation did not execute, so clearing the pending creation claim risks a
DUPLICATE issue. On a mutation, rate-limit / auth / not-found GraphQL
errors now stay ambiguous (ambiguous:isMutation) and keep the pending link
for marker recovery; reads remain definitive; HTTP-status auth (401/403),
rate-limit (429/400) and not-found (404) remain definitive in mapHttpError
(covering the expired-key case). Honors the invariant "duplicate
prevention takes priority over auto-retry when the outcome cannot be
established." An independent 4-model frontier panel ruled the prior
definitive form unsafe; the fully-correct code+data classifier is logged
as a T5.3 follow-up that needs real Linear response bodies (live dogfood).

Tests: mutation rate-limit/auth/not-found now assert ambiguous; reads stay
definitive; opaque and HTTP-status cases unchanged. Full suite green (366).

- linear-client: classify GraphQL/HTTP errors on the FULL redacted text and
  truncate only the detail returned, so an identifying keyword past char 300 is
  no longer dropped and misread as LINEAR_UNKNOWN_ERROR (mapGraphqlErrors +
  mapHttpError). Regression test added.
- ROADMAP: mark T5.2's real-repo GitHub dogfood gate COMPLETE (Issue #24),
  reconciling with the README; T5.3's real-workspace dogfood stays pending.
- TRD 5.3: name the actual rotation credential reader (listAllAdapters, called
  by scripts/rotate-encryption-key.ts); note listAdaptersForProject is unused.

Not changed: the mutation GraphQL-error ambiguity (re-flagged) stays ambiguous
per the frontier panel + CodeRabbit; the allowlisted-code classifier requested
is the logged T5.3 follow-up gated on real Linear response bodies (dogfood).
HTTP-401 auth stays definitive in mapHttpError, covering the expired-key case.

Full suite green (367).

Addresses two CodeRabbit review comments on PR #27:
- T5.3 detailed status still said "offline-verified" with a remaining
  real-workspace acceptance gate; it was dogfooded live in PRs #25/#26.
  Updated to "dogfooded in a real Linear workspace" and marked the gate cleared.
- T5.4 entry labeled "unit-tested"; it has both unit
  (tests/unit/revoke-credential-args.test.ts) and integration
  (tests/integration/revoke-credential.test.ts) coverage. Relabeled
  "unit- and integration-tested".
