## v2.6.11-close-hooks-staging — 2026-06-01
The two v2.6 follow-ups left after `v2.6.10-lifecycle-hardening`. **Server close-hook caller:** `apps/server` (BooChat) now fire-and-forgets BooCoder's Phase-3 close hooks so warm agent backends + worktrees tear down *immediately* on delete/archive instead of waiting for the idle-evict/reaper backstop — a new `coder-notify.ts` `notifyCoderClose(kind,id)` (reusing the v2.6.2 `BOOCODER_URL` reach, never-rejects) is `void`-called after the WS frame at session-delete (`POST /api/sessions/:id/close`) and chat archive / archive-all / delete (`POST /api/chats/:id/close`); an unreachable coder can never block or fail the user's delete/archive. **Staging-boundary hint (task 3.7):** the BooCoder DiffPanel now shows a muted one-liner when the selected provider can't see another agent's unapplied worktree edits — native boocode selected + external-agent-staged changes (or vice-versa) → "<agent>'s edits live in its worktree — BooCode won't see them until applied" — derived purely from the per-change `agent` + current provider, no new state. 6 new server tests (`coder-notify`), 537 server tests pass; web + server tsc/build clean. **With these the v2.6 openspec is fully closed** — only the live Smoke 2/2b/3 remain (manual exercise).
## v2.6.10-lifecycle-hardening — 2026-06-01 ## v2.6.10-lifecycle-hardening — 2026-06-01
v2.6 Phase 3 (the last phase) — lifecycle hardening of the warm-process backends. **Idle eviction + LRU cap:** the agent pool runs a 60s sweep that evicts backends/sessions idle past `AGENT_POOL_IDLE_TTL_MS` (30 min default) and any beyond `AGENT_POOL_MAX_LIVE` (10, LRU) — **never a busy one** (in-flight turn, double-checked via a new `isBusy()` backend hook); the worktree persists (DB-backed) and the next turn re-spawns + reattaches. The eviction/LRU/restart decisions are factored into a pure `lifecycle-decisions.ts` (modeled on the inference `selectPruneTargets` pattern). **Crash recovery:** lifts openchamber's health-monitor + busy-aware-restart + consecutive-failure + stale-busy-grace state machine into `opencode-server.ts` (with port reclaim) and `warm-acp.ts` — an opencode server crash settles in-flight turns as failed, marks the rows `crashed`, and recreates fresh sessions (a fresh server can't hold the old in-memory id), while a warm-ACP child crash re-`session/new`s next turn; the F.1 turn-guard and U.6 usage are preserved (their tests still pass). **Worktree reaper:** a periodic reaper removes orphan on-disk worktrees (no live `worktrees` row, 1h grace) behind a superset-style preflight that skips dirty/unpushed/unmerged work, with Paseo-style soft-delete (`status='archived'`). Plus close hooks (`/api/chats/:id/close`, `/api/sessions/:id/close`, awaiting the apps/server caller) and diff re-baseline after `apply_pending`. Built test-first — 35 new tests (`lifecycle-decisions` 22, `agent-pool` 13) + a DB-opt-in reconnect integration test; 215 coder tests pass, tsc + build clean. **This completes v2.6** (Phase 0–3 + F.1 + Phase 1-UX). Remaining follow-ups (out of v2.6 scope): the apps/server close-hook caller, the 3.7 DiffPanel staging-boundary hint (frontend), and live Smoke 2/2b/3. v2.6 Phase 3 (the last phase) — lifecycle hardening of the warm-process backends. **Idle eviction + LRU cap:** the agent pool runs a 60s sweep that evicts backends/sessions idle past `AGENT_POOL_IDLE_TTL_MS` (30 min default) and any beyond `AGENT_POOL_MAX_LIVE` (10, LRU) — **never a busy one** (in-flight turn, double-checked via a new `isBusy()` backend hook); the worktree persists (DB-backed) and the next turn re-spawns + reattaches. The eviction/LRU/restart decisions are factored into a pure `lifecycle-decisions.ts` (modeled on the inference `selectPruneTargets` pattern). **Crash recovery:** lifts openchamber's health-monitor + busy-aware-restart + consecutive-failure + stale-busy-grace state machine into `opencode-server.ts` (with port reclaim) and `warm-acp.ts` — an opencode server crash settles in-flight turns as failed, marks the rows `crashed`, and recreates fresh sessions (a fresh server can't hold the old in-memory id), while a warm-ACP child crash re-`session/new`s next turn; the F.1 turn-guard and U.6 usage are preserved (their tests still pass). **Worktree reaper:** a periodic reaper removes orphan on-disk worktrees (no live `worktrees` row, 1h grace) behind a superset-style preflight that skips dirty/unpushed/unmerged work, with Paseo-style soft-delete (`status='archived'`).
