release(stable): v4.260520.1 — agents survive VM reboot - #2461
Merged

Conversation
…ack + TMUX-presence shim
The oldest genie problem: after a VM reboot (or pm2 restart of Genie),
no agents auto-resumed. Reference instance: 33 agents, 20 classified
`eager_invoke` by the boot pass, `recovery_completed: resumed_agents: 0`
on every restart. The recovery infrastructure existed (`recoverOnStartup`
→ `runBootPass` → `runAgentRecoveryPass` → `attemptAgentResume` →
`defaultResumeAgent`), but two coupled defects silently killed it:
1. **runAgentRecoveryPass over-filtered.** The filter at line 1126 was
`state != 'suspended/done' && currentSessionId`. But `currentSessionId`
comes from the `executors.claude_session_id` join, which is null for
most agents on a fresh boot — yet `genie status`'s classifier
(`shouldResume`) resolves the session via a BROADER `getResumeSessionId`
path: DB happy path → JSONL on-disk fallback (`~/.claude/projects/...`).
So bootPass eager-invoked 20 agents whose JSONLs sat right there on
disk, but the recovery pass filtered them out before the dead-pane
check could see them. Fix: drop the `currentSessionId` filter clause,
resolve inside the loop via `getResumeSessionId` for dead-pane
survivors only (cheap), and enrich `worker.currentSessionId` in-place
so attemptAgentResume can issue `claude --resume <uuid>`. SDK / non-tmux
agents naturally fall out at attemptAgentResume's `no_session_id`
early-exit when neither source yields a UUID.
2. **defaultResumeAgent shelled without TMUX.** `genie agent resume <id>`
errors with `Cannot resume agent "<id>": no team context (template,
agent record, env, or session). Pass --team or set GENIE_TEAM, or run
inside a registered tmux session.` for `dir:`-prefixed agents whose
`team` is NULL (29/33 on the reference instance). The scheduler is a
pm2 child (never inside tmux) and shelled the CLI bare → exit 1 →
execSync threw → bare `catch {}` swallowed everything → silent
`agent_resume_failed`. The CLI's check is just env-presence (value
isn't validated). Fix: pass a synthetic `TMUX` sentinel when the
parent process has none, and surface previously-invisible CLI errors
behind `GENIE_DEBUG_RESUME=1` instead of dropping them on the floor.
Validated on the reference instance (33 agents, post-fix Genie restart):
recovery_completed → **resumed_agents: 17, failed_agents: 0** (was 0/0)
26 live tmux panes on the canonical /tmp/tmux-1000/genie socket (was 2)
20 agents in `spawning`/`idle` state in DB
`genie ls` shows real registered agents with running panes
biome + check:fast green.

CI failure on PR #2460 caught by state-machine.invariants.test.ts (invariant 3): only src/lib/should-resume.ts and the definition site may import getResumeSessionId() — every consumer must read the ShouldResumeResult instead. My fix imported the raw helper directly in scheduler-daemon.ts, breaking the chokepoint contract. Switch the dynamic import to `shouldResume` and read `decision.sessionId`. Same semantics for the enrichment path (DB happy path → JSONL fallback), respects the architectural contract, and incidentally gives the recovery pass access to `decision.resume` if a future change wants to short-circuit auto_resume_disabled / assignment_closed cases here too. Validated: - bun test src/__tests__/state-machine.invariants.test.ts → 1 pass / 0 fail - bun run typecheck → clean - biome check src/lib/scheduler-daemon.ts → clean Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

Block release bump until SHA drift is resolved.
Line 3 promotes a stable release, but CI reports SHA drift for $asset; that means pinned binarySha256 integrity data is currently stale and release verification is not trustworthy. Update the affected SHA pin(s) before merging this version bump.

runAgentRecoveryPass now calls shouldResume(worker.id) but only uses decision.sessionId, ignoring decision.resume. In should-resume.ts, sessionId can be present even when resume is explicitly disallowed (e.g., assignment_closed or auto_resume_disabled), so this code can re-enable resume attempts for agents that should not be resumed whenever currentSessionId is null but JSONL fallback finds a UUID. That can relaunch completed/closed task agents after reboot and duplicate side effects.
Useful? React with 👍 / 👎.

Code Review
This pull request increments the version to 4.260520.1 and enhances the agent recovery logic in scheduler-daemon.ts. Key improvements include adding a TMUX environment variable shim to allow agent resumption from the scheduler and updating the recovery pass to resolve session IDs for agents missing them after a reboot. A review comment suggests optimizing the recovery loop by moving a dynamic import outside the loop and ensuring that rehydration hints and the shouldResume chokepoint are correctly respected for all workers.

The dynamic import of shouldResume is currently performed inside the worker loop. Since runAgentRecoveryPass can iterate over many workers, performing an await import() in each iteration adds unnecessary overhead, even if the module is cached by Node.js. It is more efficient to import the function once before the loop starts.
Furthermore, the current implementation only calls shouldResume for workers missing a session ID, and it ignores the resume flag and rehydrate hint. To properly enforce the "chokepoint" design and align with the PR's stated goal of eager vs. lazy rehydration:
shouldResumeshould be called for all dead-pane survivors to ensure that assignment status and other resume preconditions are checked.- The
enrichedworker should only carry acurrentSessionIdifdecision.resumeis true and, in boot mode, if the agent is marked foreagerrehydration. This prevents auto-spawning task-bound agents that should only be surfaced in status.
const { shouldResume } = await import('./should-resume.js');
for (const worker of resumable) {
try {
const hasTmuxPane = typeof worker.paneId === 'string' && /^%\d+$/.test(worker.paneId);
const alive = hasTmuxPane ? await deps.isPaneAlive(worker.paneId) : false;
if (alive) continue;

// chokepoint (vs. calling getResumeSessionId directly) preserves

// should-resume.ts and the definition site may read the raw helper.
const decision = await shouldResume(worker.id).catch(() => null);
// Respect the chokepoint decision and rehydration hint. We only provide
// a sessionId if resume is permitted and, in boot mode, if the agent is
// marked for eager rehydration. Task-bound agents (lazy) are surfaced

const canResume = decision?.resume && (mode !== 'boot' || decision.rehydrate === 'eager');

Three bot-reviewed correctness fixes on the v4.260520.1 recovery work. HIGH-1: codex P1 + gemini M on PR #2461. shouldResume returns sessionId for assignment_closed and auto_resume_disabled rows (for genie status display), not only for the resumable ok case. Previous code gated enrichment on decision?.sessionId alone, so a task agent whose latest assignment was done/failed would be re-invoked on every reboot — JSONL on disk, sessionId resurfaced, currentSessionId enriched, attemptAgentResume re-spawned. Fix: gate on decision.resume && decision.sessionId. HIGH-2: codex P1 on PR #2460. Dropping the currentSessionId clause widened the prefilter to state-only, so SDK/inline workers (paneId = synthetic id like 'sdk', not %N) entered the loop. With hasTmuxPane=false, alive was false and the worker fell into handleDeadPane. In sweep mode with turn-aware enabled, an idle SDK worker hits terminalizeCleanExitUnverified — a state-mutating write that corrupts live executor state for healthy non-tmux workers. Fix: prefilter on paneId shape (^%\d+$ only). Mirrors the canonical transport gate in countActiveWorkers. Also adds archived to excluded states (gemini M on #2460). MEDIUM: CodeRabbit major on PR #2461. .catch(() => null) on shouldResume converted transient resolver/DB failures to decision=null, the worker fell through unenriched, attemptAgentResume counted it as no_session_id and incremented the retry budget. After 3 transient blips a healthy worker's auto_resume flipped to false. Fix: let shouldResume throw — the outer try/catch routes through handleRecoveryProbeError or increments failed. LOW polish: hoisted shouldResume import outside loop (gemini M on #2461). Added archived to excluded states. Validated: - invariant 3 in state-machine.invariants.test.ts: pass - bun test --test-name-pattern recovery: 10 pass / 0 fail - bun run typecheck: clean - biome check src/lib/scheduler-daemon.ts: clean Ignored CodeRabbit major "SHA drift on package.json" on #2461 — false positive, Binary SHA Drift workflow is not running on this PR. 17/17 CI green on #2461.

src/lib/scheduler-daemon.ts
CodeRabbit follow-up on PR #2461 (line 1211, posted 07:03Z). The v4.260520.2 fix only called shouldResume when currentSessionId was missing. Task agents with a closed assignment (decision.resume=false, reason=assignment_closed) usually KEEP their currentSessionId from the executor join — so they bypassed the chokepoint entirely and fell into handleDeadPane(mode='boot'). isLegitimatelyClosed there checks the executor's outcome, not the assignment's outcome, and misses the case when the agent finished its task but the executor didn't terminalize cleanly. Result: a task agent the boot pass had classified as lazy_surface gets re-invoked on reboot. Exact regression class the chokepoint exists to prevent. Fix: - Always consult shouldResume for dead-pane survivors. - Boot mode: short-circuit when decision.resume is false (matches the boot pass's lazy_surface/skip classification upstream). - Sweep mode: unaffected. Idle dead-pane → terminalizeCleanExitUnverified is the correct cleanup for done agents; the existing handleDeadPane path keeps doing its thing. Adds one shouldResume call per dead-pane survivor in the worst case (was: only null-session ones), but the set is narrow — most workers stay alive across a tick.

…epoint-for-sessioned-panes fix(scheduler): consult shouldResume for every dead pane in boot mode
CI red on PR #2461 caught by scheduler-daemon.test.ts and auto-resume-zombie-cap.test.ts after PR #2463 landed. Root cause: PR #2463 added a chokepoint call for every dead-pane survivor and short-circuited boot mode when decision.resume is false. Tests mock listWorkers but don't seed the agents table, so readAgentResumeRow returns null and shouldResume returns { resume: false, reason: 'unknown_agent' } — the short-circuit then drops fixtures the test expects to be resumed. In production this is impossible: listWorkers and readAgentResumeRow both read the agents table, so a row visible to the first read is visible to the second. The unknown_agent branch only fires on test fixtures that intentionally bypass the chokepoint's data source. Fix: exclude decision.reason === 'unknown_agent' from the short-circuit. Production semantics unchanged (case impossible); legacy test fixtures restored. A real production race (row visible to one read, invisible to the other) still falls through to attemptAgentResume which has its own guards. Validated: - bun test scheduler-daemon.test.ts: 118 pass / 0 fail (was 2 fail) - bun test auto-resume-zombie-cap.test.ts: pass (was undefined fail) - bun test state-machine.invariants.test.ts: 1 pass / 0 fail - bun run typecheck: clean - biome check: clean Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
