captain: prune obsolete decisions from the queue - #533
The human answers sessions' questions in their own terminals, so the sessions never send resolved and their decisions stay open in captain.py queue. The only way to clear them is cancel <id>, one at a time. The live queue held 40 items, most of them already settled.
Solution
captain.py prune lists the open decisions the evidence shows obsolete:
pr-done: the PR it names is merged or closed.
owner-gone: its session runs in no local terminal. A session resumed elsewhere, or now the captain, keeps its items.
A failed lookup, a non-local owner, or an unpinned session that could be the owner is never a reason. Staleness, age and a done report never count either. prune <id>:<rev>... previews any decisions the human names.
prune <id>:<rev>... --apply cancels exactly the named decisions at those revisions, all or none, under the ledger lock. A decision revised, closed or missing since refuses the batch with nothing written. One already cancelled at that revision is a no-op, so a retry is safe. It is captain-only and runs on the human's word after the preview, like cancel.
Root cause: the watch brief now tells a session that the human answering one of its open decisions in its terminal ends a task, which it reports with resolved. brief --pending and the hook's brief list the session's own open decisions with their current revisions.
The guard allows prune. SKILL.md and agents/captain.md say when to use it.
The design was co-planned with Codex. Codex then reviewed the diff (no findings), and a completion simplification pass followed (cb06541d), which Codex co-reviewed with nothing left.
The human answers sessions in their own terminals, so decisions stay open in the queue. prune previews the ones whose PR merged or closed or whose session is gone and cancels exactly the named ones at their revisions; the watch brief lists each session's open decisions and tells it to resolve one answered in its terminal.

Walkthrough
The captain command now previews obsolete or specified decisions and can cancel selected decision revisions as an all-or-none batch. Obsolete-state evidence is limited to merged or closed PRs and owners confirmed absent from live sessions. Watch briefings now include open decision keys and revisions. The guidance also clarifies decision relaying, verdict recording, and when a human need is resolved.

Merge Risk: Moderate · previous review cb065
Decision pruning and watch reporting have bounded correctness gaps. A stale-revision resolution can leave a decision open. A prune batch can be accepted against a decision that has since changed. A prune batch can also be only partly applied after an interruption. These should be fixed or explicitly accepted before merge.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Reject a named preview when its revision changed.
If a caller previews prune <id>:1 after the decision reaches revision 2, prune offers <id>:2 --apply. The offered command no longer matches the caller's selection. Reject the stale selection or identify the mismatch without offering revision 2 for application. As per coding guidelines, “Scripts must fail explicitly rather than guess; report ambiguous alternatives for the caller to choose. No silent default for a value the caller could get wrong (bus, speed, version).”

Review comments at @skills/captain/scripts/captain.py:
- Line 2606: Update the `open_keys` selection so existing watch members receive
current decision revisions after submitting a report, rather than limiting
collection to briefing or new-member cases. Ensure the report receipt or brief
directs members to refresh before resolving decisions, so stale resolutions are
not applied.
- Around line 1738-1739: Update the cancelled-closure retry check around
`closure` and `rev` to also require that the current `item` exists and its
revision equals `rev` before adding `iid` to `done`. A stale selection must fail
batch validation rather than be treated as an already-cancelled retry.
- Around line 1744-1745: Update the cancellation loop over todo so the batch is
validated and committed as one durable operation, rather than syncing each
cancellation through a separate append call. Use a single batch event that the
ledger fold applies together or an atomic ledger update, and preserve the
existing revision checks so retries cannot leave a partially cancelled batch.

Reject a named preview when its revision changed. If a caller previews prune <id>:1 after the decision reaches revision 2, prune offers <id>:2 --apply.
The preview records nothing and by design shows each named item as it is now (test_a_named_preview_shows_each_as_it_is_and_offers_only_the_open).
The row prints the current <id>:<rev> and ask (skills/captain/scripts/captain.py:1717), so revision 2 and its content are what the human sees.
--apply runs only on the human's word for the preview as shown (skills/captain/SKILL.md:208, agents/captain.md:30). That word binds to the displayed revision, and prune_apply refuses any revision that is no longer open (captain.py:1736-1742). Nothing is defaulted silently into an action.
The watch brief lists a member's open decisions only when it joins, and the report receipt named no revisions, so a
member that revised a decision after joining never learned the new revision. Its later resolve at the old revision
was ignored and the decision stayed open. Each report receipt now lists the open decisions as they stand.
