… (S054) api-server captured the token once at boot while the secrets handler called loadOrCreateApiToken() fresh on every request; an external rotation or an unwritable token dir left the two permanently disagreeing about the current token. getApiToken/reloadApiToken share one in-memory cache between both consumers, and a persist failure now logs a warning instead of failing silently.
…pid after binds Boot failures on the prod path used to leave a live-pid zombie: a stale rt.pid could get written before the socket/API binds even attempted, so a failed boot exited without ever removing it. runDaemon() now wraps its body in try/catch (log.fatal + flush + exit 1 on any failure), and rt.pid is only written once both servers.socket and servers.api are assigned. installCrashHandlers gains an opts.booting predicate: unhandledRejection is fatal + exit 1 while true (boot phase, nothing worth staying up for), and logs only (today's behavior) once bootPhase flips to "ready" right before "daemon ready".

Review fix (round 1): runDaemon() now catches and exit(1)s internally on boot failure, so startDaemon()'s outer try/catch never runs, and its JSDoc claiming otherwise was misleading. Replaced with a one-line comment stating the real constraint.

A pre-startDaemon throw (e.g. a corrupt events.db) now lands in daemon-stderr.log instead of vanishing down a discarded fd 2. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
…linked or case-variant root matches lsof (S097)
…ery root retainedTrashRoot now takes the pool root directly (join(poolRoot, ".trash")) instead of deriving .worktrees/.trash from repoPath. retireTree derives the pool root from dirname(path), the root the tree actually lives in, so a legacy tree retains under the old root and a new tree under the new pool root with no migration step. ensureInfoExclude only runs when that pool root sits inside the repo. reapExpiredTrash now takes an array of roots (matching reapTrashInRoots) so reapRepoTrash in worktree-reconciler.ts sweeps both the legacy <repo>/.worktrees and the configured cfg.root for expired retained trees, not just one hardcoded location.
…uctive callers abort on a dropped write setKvValueCritical (kv-blob.ts) and replaceEndpointClaimsCritical (endpoint-claims-store.ts) retry on busy and report whether the write landed, instead of warn-and-drop. saveRegistry and saveClaims now return that boolean; saveRegistry only bumps the epoch on a landed write. patchTree (handlers/worktree.ts) returns the boolean; the provision claim aborts with claim-write-failed on a dropped write instead of proceeding as though it owned the tree. create.ts's final registry flip aborts the same way, leaving the row "creating" for the reconciler's existing orphan sweep to retry.

…sion), caller pid and multiplexers/editors spared
…sh aborts the pass stashChangesAsync now returns the GitResult instead of void. freshenOne checks the push exit code and the resolved Desktop marker before ever setting stashName, aborting (fail + return false, no pop) on either failure, and re-checks git status is clean before the ff, mirroring autoReturnMain's existing re-check.
…p emits a user-visible event Gate freshenCandidate's main branch behind loadWorktreeAppConfig().enabled (idle-main freshen touches the user's live checkout, so it stays opt-in even when the worktree:freshen daemon handler is invoked directly, bypassing runOnce's own pass-level gate). Re-check blockers for main right after the discard reset, before the stash block: a blocker there means the user started editing during the fetch's up-to-5-minute window, so freshenOne aborts without stashing and without counting it as a failure. A failed stash pop is now a hard failure: popStash returns a boolean, emits worktree:stash-conflict on pop failure, and the post-ff call site fails the pass instead of silently continuing.
…uses a changed tree
… of pruning it A registered worktree path absent from git ground truth for one pass no longer gets pruned outright: it holds for MISSING_PRUNE_PASSES (3) consecutive passes, tracked via TreeRecord.missCount, before the row is dropped. A path that reappears clears missCount. The unconditional git worktree prune is skipped for a pass where any registered tree's parent directory is currently unreadable. scrapTree now refuses to trash a directory with no .git entry, so a desynced registry row can't rm -rf content rt did not create.
…nto ephemeral ownership adopt's final promotion block (the foreign hand-made path, not the parking-lot branch) now leaves a tree exactly as reconcileRepoRegistry stamped it (kind unmanaged) unless the caller passes --claim, which promotes it to ephemeral/claimed/merge as before. Payload, handler data, CLI output (human + json), and the command-tree-def flag all carry claim through; the adopt handler test is flipped to pin unmanaged as the default and adds a claim:true case.

📝 WalkthroughWalkthroughThis PR hardens worktree storage, persistence, reconciliation, disposal, restoration, endpoint claims, adoption, and CLI behavior. It also adds daemon status reporting, command-tree wiring, tests, and reference documentation. ChangesWorktree engine hardening
Estimated code review effort: 5 (Critical) | ~120 minutes Merge Risk:🟠 High · up to This PR adds destructive worktree restoration and endpoint lifecycle changes, but the current implementation can accept path segments outside the configured pool, leave partially restored worktrees behind after failure, and mishandle a few release and liveness edge cases. Those issues can cause unintended filesystem changes, failed retries, or overly broad endpoint release, so the PR should not merge until the high-impact restore paths are fixed.

In `@commands/endpoint.ts`:
- Line 163: Update the argument parsing around roleFlagIdx and roleValueIdx to
reject --role when it has no following value or when the next token is
option-like, before endpointRelease sends the release request. Preserve valid
role values, and add coverage for both --role and --role --json.
In `@lib/daemon/handlers/worktree.ts`:
- Around line 616-623: Validate treeName in the restore handler before
constructing the withTreeLock key or calling restoreTree: reject path separators
and the dot segments "." and ".." with the existing no-target failure response.
Keep valid tree names and the subsequent restoreTree flow unchanged.
In `@lib/endpoint/allocator.ts`:
- Around line 144-147: Update resolveClaim so a renewal or new claim never
persists a PID identity with an unavailable startTime: when pidStartTime(pid)
returns undefined, fail the claim operation or preserve the existing verified
identity without overwriting it. Ensure recycled-PID protection remains intact,
and add a regression test covering renewal when pidStartTime is unavailable.
In `@lib/state/__tests__/db.test.ts`:
- Line 180: Update the schema inspection in the database test to retain the
Database instance, read table_info into columnsBefore, then explicitly call
close() on that instance before continuing.
In `@lib/state/db.ts`:
- Around line 324-328: Update ensureEndpointClaimsStartTimeColumn so a
concurrent duplicate-column failure from ALTER TABLE is treated as success when
start_time now exists, while still propagating unrelated database errors;
preserve the existing no-op path when PRAGMA table_info already finds the
column.
In `@lib/worktree/restore.ts`:
- Around line 204-210: In lib/worktree/restore.ts at lines 204-210 and 224-225,
update the restore flow after git worktree creation to remove the newly created
worktree and branch before returning copy-failed or register-failed. Reuse the
existing cleanup mechanism, keep the retained entry intact until restoration
fully succeeds, and apply the same compensation at both affected failure sites.
In `@website/docs/reference/worktree/restore.mdx`:
- Line 15: Update the worktree restore usage syntax to show the tree argument as
optional, changing the command declaration from the required tree form to [tree]
[flags] while leaving the rest of the documentation unchanged.
