…y_for_agent A stale `claimed` plan-subtask used to deadlock a wave forever. When the worker holding it went idle (quota, crash, abandoned context), the queue surfaced a `rescue_candidate` and told callers to run `rescue_stranded_scan` — but the codex worker fleet is policy-prohibited from rescuing other agents' claims. Result: every agent correctly refused the rescue suggestion and idled, polling forever while one dead claim blocked the wave. `task_ready_for_agent` now auto-releases claims older than `STALE_PLAN_SUBTASK_CLAIM_MS` (default 1h) before computing the available set; released subtasks appear as claimable in the same response. Each release writes one `plan-subtask-claim` observation with `status: 'available'` + `rescue_reason: 'auto-released-stale-claim'`, matching `bulkRescueStrandedSessions`'s audit shape. * New schema arg `auto_release_stale_claims: false` preserves the legacy rescue-candidate surface for telemetry / admin callers that want to observe stale state without mutating it. * New response field `auto_released_stale_claims[]` reports which claims were released this tick. * New `autoReleaseStalePlanSubtaskClaims(store, plans, options)` export from `@colony/core` shares the sweep with future consumers (autopilot tick, etc). Tests: `apps/mcp-server/test/ready-queue.test.ts` adds two cases — auto-release happy path produces a claimable result + reports the release, and `auto_release_stale_claims: false` preserves the legacy rescue-candidate surface. The pre-existing stale-blocker test now passes the opt-out flag to keep covering the legacy path verbatim. Full mcp-server suite: 272/272 PASS.
