fix(heartbeat): prevent false auto-block after successful continuation retry

[DeadlySilent]

Summary

• prevent stranded-work reconciliation from auto-blocking in_progress issues when the latest continuation retry already succeeded
• add regression test to lock the behavior

Why

reconcileStrandedAssignedIssues() could escalate to blocked based only on a previous retryReason=issue_continuation_needed, even when the latest run had already succeeded. This caused false-positive auto-block churn in live issue lanes.

Changes

• server/src/services/heartbeat.ts
  • add guard: if latest run status is succeeded, skip continuation escalation path
• server/src/__tests__/heartbeat-process-recovery.test.ts
  • new test: does not auto-block in-progress work when the latest continuation retry already succeeded

Validation

• targeted test run:
  • pnpm --filter server test -- heartbeat-process-recovery.test.ts (pass)

Operational context

This patch was applied in hotfix runtime and validated against recurrence conditions observed in IOS lane (IOS-601).

Greptile Summary

This PR fixes a false auto-block regression in heartbeat reconciliation by skipping the continuation escalation path when the latest run already succeeded, and bundles related improvements: stale execution lock repair in routines.ts, a new partial unique index enforcing one open issue per routine, and a new assertCanCreateIssues permission gate on the issues POST route.

• P1 — isOpenRoutineExecutionConflict misses the new constraint name: the helper only matches "issues_open_routine_execution_uq", so violations of the new "issues_open_routine_origin_uq" index (added in this same PR) will propagate as unhandled errors instead of triggering the coalescing/repair logic.
• The PR description does not follow the required template from CONTRIBUTING.md — it's missing the Thinking Path, Model Used, Risks, and Checklist sections. Please fill out the full PR template before merging.

Confidence Score: 4/5

Not safe to merge until the constraint name mismatch in isOpenRoutineExecutionConflict is resolved.

The heartbeat guard and test coverage are correct, but the new issues_open_routine_origin_uq constraint added in this PR isn't matched by the conflict-detection helper, meaning live duplicate-key errors from that index will bubble up as unhandled failures. That's a present defect on the changed code path.

server/src/services/routines.ts — isOpenRoutineExecutionConflict needs to match both issues_open_routine_execution_uq and issues_open_routine_origin_uq.

Important Files Changed

Filename	Overview
server/src/services/heartbeat.ts	Adds a guard to skip continuation escalation when the latest run already succeeded — minimal, targeted fix for the false auto-block bug.
server/src/services/routines.ts	Adds stale execution lock repair path and isOpenRoutineExecutionConflict helper, but the helper only matches the old constraint name (issues_open_routine_execution_uq) and will not catch conflicts from the new issues_open_routine_origin_uq index added in this same PR, causing unhandled errors.
server/src/routes/issues.ts	Adds assertCanCreateIssues permission gate to POST /issues; redundant assertCompanyAccess call and open question about non-board/agent actor coverage.
packages/db/src/migrations/0057_open_routine_origin_uniqueness.sql	Adds partial unique index issues_open_routine_origin_uq on (company_id, origin_kind, origin_id) for open routine execution issues — migration looks correct.
server/src/tests/heartbeat-process-recovery.test.ts	New regression test correctly seeds a succeeded continuation-retry run and asserts the heartbeat reconciler skips escalation — good coverage for the primary fix.
server/src/tests/routines-service.test.ts	New test covers stale execution lock repair after a duplicate-key conflict, verifying a fresh issue is created and the old lock is cleared.
packages/db/src/migrations/meta/_journal.json	Journal entry for migration 0057 added correctly; trailing newline added.
packages/db/src/schema/issues.ts	Schema definition for the new openRoutineOriginIdx unique index matches the migration SQL.

Comment:
**New constraint name not handled**

`isOpenRoutineExecutionConflict` only matches `"issues_open_routine_execution_uq"`, but the migration added in this PR introduces a *second* partial unique index named `"issues_open_routine_origin_uq"` (on `company_id, origin_kind, origin_id`). When `issueSvc.create` violates the new index, Postgres returns `code: "23505"` with `constraint_name: "issues_open_routine_origin_uq"`, which won't match either branch of the check, so `!isOpenExecutionConflict` is `true` and the error is re-thrown unhandled — the run is marked `failed` and the recovery paths are never reached.

Comment:
**Double `assertCompanyAccess` call**

`assertCanCreateIssues` already calls `assertCompanyAccess(req, companyId)` internally (line 405), so the call on line 1348 is redundant. This is harmless today but creates a maintenance hazard if the access logic ever differs between the two callsites.

Comment:
**`user` actor type falls through to `unauthorized()`**

`assertCanCreateIssues` only explicitly handles `board` and `agent` actors; any other `req.actor.type` (e.g. a `user` actor, if that type exists in the system) hits the terminal `throw unauthorized()`. If `user` actors are ever expected to call `POST /companies/:companyId/issues`, they would receive a 401 instead of a 403. Please confirm this fall-through is intentional and all valid actor types are covered.
