fix(refocus): a selectable time budget, and a failure report that survives slow attempts - #1475
Conversation
…rness kill, and one delivery per occupant Three problems in the refocus hook, each reproduced first by running the real hook under the harness's kill with stub lookups: - No supported way to give a slow trace more time. A larger inner timeout would still be killed at the registrations' 5 s. OPENRIG_REFOCUS_BUDGET_MS (4,500 to 55,000 ms) now selects the hook's budget. Each lookup's cap scales with it, and the refocus.cjs registrations allow 60 s on both harnesses. The other hooks stay at 5 s. - Lookups each under their own 2 s cap could together pass 5 s. The harness killed the hook, nothing was delivered, and no failure was recorded, so three in a row raised no issue. Every lookup, the first `rig queue whoami` included, is now cut to what's left of the budget. A lookup with no time left reports its gap, and the attempt delivers what it has and records the failure. - Overlapping hook runs for one occupant lost a PostCompact that landed during a delivery, and two overlapping prompts delivered the same refocus twice. State reads and writes now take a per-occupant lock file, held for milliseconds, never across the trace. A prompt claims the delivery, and an overlapping prompt leaves it alone. At the end the state is re-read, and only the pending the delivery claimed is cleared. A claim left by a killed hook lapses after the budget plus 2 s. With no budget selected, the delivered payload is byte-identical to before in every measured case that finished. The one changed default is a fire that used to be killed: it now ends as a reported gap. A hook that hangs outside its lookups can now hold a prompt for up to 60 s instead of 5 s. openrig-core goes to 0.1.12 so installed copies pick this up.

Retry lock acquisition instead of proceeding without ownership.
lock() returns after one second without setting lockHeld, but both callers continue to read and persist state. A concurrent hook can therefore overwrite a pending event or delivery claim without owning the lock.
An immediate exit is not a safe fix for the non-prompt branch. That branch persists PostCompact and other pending events only after the lock call. The hook registrations provide no repository-owned retry or durable handoff for an event skipped by that exit. Keep retrying lock acquisition, or add an equivalent durable fallback, before any state read-modify-write.

…t, and never write state without the lock Two gaps in the previous commit: - The issue report after a third failed attempt still got min(1.5 s, 4.5 s - uptime). An attempt that used its whole budget therefore spawned the report with a ~1 ms timeout, every time, so that episode was never reported. Hosted CI caught it. The report now gets its own 1.5 s after the hook's budget, which still ends well inside the 60 s outer bound. - A hook that waited 1 s for an occupant's lock went on without it, reopening the race the lock closes. It now waits past the stale age. A live holder keeps the lock for milliseconds, and a killed one's lock is broken at 5 s, so the wait always ends holding the lock. Only a lock file that can't be created at all (an unwritable state folder) leaves the hook going on without it, rather than failing the turn. The expiry test's stub now answers an issue report after 200 ms, so a near-zero report timeout fails it on every run instead of sometimes. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

…orded inside the 60 s bound After the budget, a delivery can still spend up to 1.5 s on the failure report and up to 6 s waiting for the occupant's lock to record its outcome. At a 55 s budget that could pass the registrations' 60 s, and a hook killed there would leave its claim and pending state behind, so the refocus could be delivered again. The longest budget is now derived: 60 s - 1.5 s - 6 s - 0.5 s margin = 52 s. The registrations stay at 60 s. The default (4.5 s) is unchanged. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

The trace gap is what tells the 52 s limit from 55 s. The elapsed-time bound only checks that the hook ended, so it now allows 30 s instead of leaving under 400 ms for start-up and post-trace handling. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
…s no owner; main's default results
Round 2 of the review:
- The state lock moves to refocus-lock.cjs and is owner-safe:
- A lock holds its owner's token and is released only by that owner.
- A stale lock (its owner killed) is taken over by moving it aside and
checking it is the one seen stale. A competitor's fresh lock moved
by mistake is put back, so two hooks never both hold it.
- Every path ends by its deadline. Something at the lock path that
can't be read or moved (a directory, a dangling link, an unwritable
folder) fails at once instead of spinning to the 60 s kill.
- A hook that can't take the lock goes on as it did before there was
a lock, and says so on stderr.
- A delivery claim now lasts as long as its owner can still be running
(budget + failure report + closing lock + 0.5 s), so no second prompt
delivers while the first is alive. After a killed hook, re-delivery
waits that long (12.5 s by default).
- With no budget selected, every lookup keeps its fixed 2 s cap,
unclipped, so a default fire gives main's result, content-REF seats
included. A selected budget still scales and clips the lookups.

…, not taken for a dangling link After a read found the lock gone, any lstat hit was reported as a dangling link. If the holder released and another hook took a fresh lock in between, the waiter gave up and went on without the lock while it was held. Now only a symbolic link at the path is a dangling link; anything else is waited for, within the deadline. The default-parity test's lookups now take 1.7 s rather than 1.9 s each. Together they still pass the old 5 s bound, but each leaves room under its 2 s cap for a slow runner's process start-up. Hosted CI's macOS daemon run timed out the content REF at 1.9 s.

…p the budget and the report window The lock could not be made exclusive with path-based file operations: a stale takeover acts on a path, not on the lock it inspected. So this change no longer claims to serialize overlapping hook runs. Removed: refocus-lock.cjs, the delivery claim, pendingSeq, and their tests. The hook is main's again, plus: - OPENRIG_REFOCUS_BUDGET_MS, from 4,500 to 52,000 ms (pinned, not derived), scaling and clipping the lookups only when selected; - default lookups keeping main's fixed 2 s caps and old-CLI retry; - the failure report getting its own 1.5 s after the attempt's lookups, measured from the actual elapsed time, so a slow default attempt's third failure is still reported; - the 60 s refocus.cjs registrations (every other hook unchanged). Overlapping hook runs for one occupant keep main's behaviour: a PostCompact can be lost, or a refocus delivered twice. That gap stays open. The tests now characterize it instead of asserting a fix, and check that a claim or pendingSeq left on disk by the earlier candidate doesn't stop a hook delivering what is due.

Approved at 01b74ee. A seat can give a slow refocus trace more time with OPENRIG_REFOCUS_BUDGET_MS (default 4,500 ms, the current behaviour; up to 52,000 ms), and a slow attempt's failure report now gets its own window. Both change-only reviews and the required CI (8/8) pass at this head, and the merge with current main is clean.

What a user gets
A seat can give a slow refocus trace more time, and a slow attempt is reported honestly. This is a budget-and-reporting
change. It is not full refocus parity: overlapping hook runs are still not serialized (see "Not resolved").

OPENRIG_REFOCUS_BUDGET_MSin a seat's environment, from 4,500 ms (the default) to52,000 ms. With a budget selected, each lookup's cap scales with it (the trace gets about 23 s at 52 s) and every
lookup is clipped to what's left, so a slow attempt ends as a reported gap. A single 45 s trace call is not provided.

slow default attempt's third failure still files the issue. An unconfirmed report keeps its id for the next attempt,
as before.
Not resolved
Two hook runs for the same seat and occupant are still not serialized, as on
main. If they overlap, a PostCompactrecorded during a delivery can be lost, and one refocus can be delivered twice. This is reproduced between hook processes
(the tests characterize it). Whether a harness overlaps these events for one session is not established, so the gap is
open, not shown to be safe. A per-occupant lock was tried in this PR and removed: a stale-lock takeover with path-based
file operations can't guarantee one holder.
