Preserve productive evidence on duplicate completion writes.
A repeated record_completion call uses the default zero values and overwrites an earlier productive record. The next should_dispatch(..., require_productivity=True) call then permits retry-unproductive for work that already produced progress.
If prior is terminal and has the same key, merge its normalized progress into the new record. Add a regression case that records commits=1, repeats completion without progress arguments, and confirms duplicate suppression remains active.

There was a problem hiding this comment.
The final assertion follows dispatch(storage, head="b" * 40), which starts a different head and explicitly resets the streak. The same-head post-cooldown completion is asserted to remain in unproductive-cooldown immediately above it. The named suite passed all sixteen cases on this exact implementation. Please re-evaluate the finding with the intervening new-head dispatch included; the duplicate productive-completion finding is separate and is routed to recovery.

Superseded by #3436, which merged for #3433 and closed it. Closing this rather than reviving it, because the branch now conflicts with main across the same files. Crediting what this PR got right, since it is not nothing: the timed cooldown here is a better design than the one I merged. #3436 expired its retry allowance into a refusal that only a new head commit could clear, which is the original deadlock two runs later; this PR expired it into a wait that time alone clears. I have ported that, plus the Not ported: the |
…wn, not a latch (#3440) * fix(keepalive): expire the unproductive retry allowance into a cooldown, not a latch The #3433 fix granted a bounded number of re-dispatches after a zero-output run and then refused until the head changed. That refusal is the ORIGINAL deadlock moved two runs later: only the agent being refused could push the commit that would clear it. The allowance now expires into a 30-minute cooldown measured from the last completion. Time alone clears it and the hourly keepalive sweep wakes it, so nothing the gate forbids is needed to open it. A `completed_at` that cannot be parsed lets the dispatch through -- a gate that cannot measure itself must fail toward motion rather than hold the loop shut on the strength of its own blindness. The design came from the fleet's own parallel attempt at #3433 (#3435), which reached the cooldown before I did; that PR is superseded by the merged #3436 but was right about this. Its documentation gap is closed here too: docs/keepalive/GoalsAndPlumbing.md now carries the full decision table, the unmeasured-vs-unproductive distinction, and why the expiry is a timer. Deliberate-break gate: making the cooldown never expire fails test_dispatch_resumes_once_the_cooldown_has_elapsed and test_unmeasurable_cooldown_fails_toward_motion; restoring it passes. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * test(keepalive): pin cooldown re-arming after expiry Review was right that the expiry test alone cannot tell a working re-arm from two regressions: a tally that keeps climbing (so each window is measured from an ever-staler completion) and an expired window that never closes again (so a permanently broken runner is re-dispatched forever). The new test records a second zero-output completion after the first cooldown expires and asserts both a fresh refusal and the capped tally.

Automated Status Summary
Scope
The keepalive runner-dispatch debounce is keyed on
(head_sha, provider)and records adispatch as
completedregardless of whether the agent produced anything. When an agentrun exits reporting success but did no work, the key is burned for that head, and the only
thing that can change the head is a commit from the very agent the debounce now refuses to
dispatch. That is a closed latch: clearing it requires the action it forbids.
