Source: Issue #3433

Closes #3433

Automated Status Summary

Scope

The keepalive runner-dispatch debounce is keyed on (head_sha, provider) and records a
dispatch as completed regardless of whether the agent produced anything. When an agent
run 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.

Observed live on 2026-09-13. stranske/Doc-Lineage #23 and stranske/Manager-Mosaic #22
each had one codex run whose sandbox failed to initialize:

bwrap: loopback: Failed RTM_NEWADDR: Operation not permitted

Codex reported this as a successful run ("Status: ✅ Success", 0 tasks complete, no
commit). Every later dispatch attempt then returned:

{"prior_status": "completed", "reason": "duplicate-completed", "should_dispatch": "false"}

Both PRs sat frozen at iteration 1/12 for four hours while the hourly keepalive sweep ran
past them.

Context for Agent

Related Issues/PRs

Tasks

  • In .github/workflows/agents-keepalive-loop.yml (consumer copy: templates/consumer-repo/.github/workflows/agents-81-gate-followups.yml), distinguish a productive completion (commit or task delta) from an unproductive one; only a productive completion burns the (head_sha, provider) key.
  • In .github/workflows/agents-keepalive-loop.yml, surface both numbers when refusing duplicate-completed: prior commits, prior task deltas, and what would drain the block.
  • In .github/workflows/agents-keepalive-loop.yml, add a bounded escape hatch: after N consecutive unproductive completions on the same head, allow one re-dispatch.
  • Add a regression in tests/workflows/test_keepalive_dispatch_debounce.py proving a completed-but-zero-output dispatch record does not block the next dispatch for the same head.

Acceptance criteria

  • Run pytest tests/workflows/test_keepalive_dispatch_debounce.py -q and retain output in the PR body.
  • The new test asserts that a completed dispatch with zero commits and zero task deltas yields should_dispatch: true on the next evaluation for the same head.
  • Deliberate-break gate: revert the productivity check so any completed record burns the key → the new test must FAIL → restore.

Summary by CodeRabbit

  • New Features

    • Keepalive processing now tracks productive progress through commits and completed tasks.
    • Unproductive completions can be retried automatically, with cooldowns to prevent excessive repeat runs.
    • Completion summaries now include completed-task progress for more accurate status reporting.
    • Hourly recovery checks can bypass normal debounce limits when needed.
  • Bug Fixes

    • Progress summaries now use current checklist results instead of stale prior state.
  • Documentation

    • Updated guidance covering productivity checks, retries, cooldowns, and recovery behavior.

🗄️ Data Integrity & Integration | 🟠 Major | ⚡ Quick win

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.

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 docs/keepalive/GoalsAndPlumbing.md section #3436 shipped without, in #3440.

Not ported: the require_productivity opt-in flag and the tasks_completed_delta second signal. The merged implementation reaches the same place through an unmeasured-means-terminal default, and a single productivity verdict avoids two independent notions of "productive" drifting apart. If the checkbox-only case turns out to matter in practice, that signal belongs inside the one verdict.

…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.

* 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.
