Follow-up to #358. The fix in this PR was reviewed on #358 but did not land#358 was squash-merged as 8323f8d while I was pushing it, so the merge captured only the first commit. This is the second one, rebased onto the new main.

What #358 shipped, and what it got wrong

#recordReadinessSweepOutcome folded a deferred report into the counts snapshot like any other pass. A deferred pass settles successfully, in milliseconds, having enumerated nothing — it returned early because another process held the discovery lease — so its zeroes replaced the last real sweep's numbers.

Where the lease is held for any length of time (the #347/#349 condition), every pass publishes candidates: 0 and the last actual enumeration becomes unrecoverable. That destroys the exact measurement #355 exists to provide, on the exact surface it exists to provide it.

Found by CodeRabbit on #358, rated Major. Correct.

The fix

The marker now lives apart from the counts. candidates/dispatched/skipped describe the last sweep that enumerated; discoveryDeferred describes the most recent pass.

published means
counts + discoveryDeferred the numbers are from an earlier pass; the most recent one deferred
discoveryDeferred alone, no counts nothing has enumerated yet on this daemon, and a held lease is why
counts, no marker the numbers are the most recent pass

The middle row is new capability, not just a repair: the previous shape could not express it at all, because sweepOutcome returned early and dropped the marker whenever the trio was absent. A daemon whose first pass defers now says so instead of publishing nothing at all.

One part of the review deliberately not taken

The review also asked to keep lastCompletedAtMs unchanged on deferral. Declining that, because it would break the #295/#296 stall derivation.

readinessReconcileInFlightMs() and derivedReadinessReconcileState() infer an in-flight pass from lastStartedAtMs > lastCompletedAtMs. Freezing the completion timestamp leaves that inequality true after every deferred pass, so a daemon deferring correctly to another owner would read as having a pass in flight — and past READINESS_RECONCILE_STALL_INTERVALS, as stalled. A false alarm on the surface this work exists to make trustworthy, and precisely the failure mode #295 was written to close.

lastCompletedAtMs still moves for a deferred pass. A test asserts that it does, with the reason inline, so it does not get "fixed" later.

Also: document every skip code

docs/deployed-diagnostics.md listed four of the fourteen FACTORY_SWEEP_SKIP_REASON_CODES. All fourteen are now there, grouped by what an operator should do about each:

  • needs a humandispatch-terminal, dispatch-retry-limit
  • transientdispatch-backoff, dispatch-in-flight, already-tracked, queued-or-escalated
  • the gate is working as configuredout-of-scope, not-ready, not-dispatchable (check the deployed safety config against the issue, not the daemon)
  • parked on other workparked-dependency, dependency-cycle
  • something threwread-failed, dispatch-failed (pair with lastErrorClass)
  • other — a code this reader's vocabulary does not know; unrecognised keys fold here rather than being dropped, so the parts keep summing to skipped

CodeRabbit, trivial. Valid.

Tests

  • a sweep that enumerates, then deferred passes — counts survive, marker appears, lastCompletedAtMs still advances
  • first-pass-defers — the marker publishes with no counts at all
  • a projection unit test for the same independence

Ablated: restoring the old single-record write fails both deferral tests, and only those.

Full suite on this branch off 8323f8d: 2081 passed, 1 skipped, 0 failed. npm run build and npm run featuremap:check clean.

Summary by cubic

Prevents a deferred readiness sweep from overwriting the last enumerating measurement and adds a measurement timestamp so readers can see staleness. Previously a deferred pass wrote zeroes and replaced the snapshot and lastCompletedAtMs implied freshness; now counts are retained, the deferral marker is independent, and counts are dated by lastEnumeratedAtMs.

  • Model/recorder: only enumerating passes update candidates/dispatched/skipped/skipReasons; discoveryDeferred tracks the most recent pass; lastEnumeratedAtMs is written with the counts using the caller’s completion stamp; lastCompletedAtMs still advances on deferral for stall detection.
  • Public surfaces: authenticated status, public health, and factory diagnose expose lastEnumeratedAtMs and keep discoveryDeferred separate from counts. Partial/invalid count trios are rejected and flagged as enumerationCountsInvalid: true, while preserving any deferral marker.
  • CLI: shows “Last enumerating sweep,” prints lastEnumeratedAt, attributes deferral to the latest pass, treats legacy deferred zero snapshots as “not attributable,” and renders invalid snapshots as “not attributable” without implying “never enumerated.”
  • Logging/health: completion logs report this pass’s skipReasons; a newer failure clears a stale deferral marker.
  • Migration: date decisions off lastEnumeratedAtMs (not lastCompletedAtMs); treat discoveryDeferred without counts as “not yet enumerated”; if enumerationCountsInvalid is true, do not infer zero or prior enumeration.

Written for commit 921b191. Summary will update on new commits.

Review in cubic

CodeRabbit, Major on #358, and correct. `#recordReadinessSweepOutcome` folded a
deferred report into the counts snapshot like any other. A deferred pass settles
successfully in milliseconds having enumerated nothing, so its zeroes replaced
the last enumerating sweep's numbers — and where another process holds the
discovery lease for any length of time (the #347/#349 condition), EVERY pass
would publish `candidates: 0` and the measurement this whole change exists to
provide would be unrecoverable.

The marker now lives apart from the counts. `candidates`/`dispatched`/`skipped`
describe the last sweep that ENUMERATED; `discoveryDeferred` describes the most
recent pass. Present together they say "these numbers are from an earlier pass";
present alone it says "nothing has enumerated yet, and a held lease is why" —
which the previous shape could not express at all, because the projection
dropped the marker whenever the trio was absent.

Not taken from the review: freezing `lastCompletedAtMs` on deferral. The
#295/#296 stall derivation reads that timestamp against `lastStartedAtMs`, so
freezing it would leave `lastStarted > lastCompleted` on every deferred pass and
report a daemon that is correctly deferring to another owner as hung after ten
intervals — a false alarm on the exact surface this work exists to make
trustworthy. It still moves; the test asserts that it does, and says why.

Also CodeRabbit, trivial: `docs/deployed-diagnostics.md` listed four of the
fourteen skip codes. All fourteen are now documented, grouped by what an
operator should do about each, with the `other` fold-in stated.

Tests: a sweep that enumerates, then deferred passes, asserting the counts
survive, the marker appears, and `lastCompletedAtMs` still advances; the
first-pass-defers case asserting the marker publishes with no counts at all; and
a projection unit test for the same independence. Verified by ablation —
restoring the old single-record write fails both deferral tests.

Review Change Stack

📝 Walkthrough

Walkthrough

Readiness reconciliation now retains counts from the last enumerating sweep, tracks lastEnumeratedAtMs separately from lastCompletedAtMs, and reports recent lease deferrals independently. Health projections, CLI diagnostics, tests, and deployed-diagnostics documentation reflect the new behavior.

Changes

Readiness reconciliation telemetry

Layer / File(s) Summary
Health contracts and projection
src/types.ts, src/orchestrator/public-health.ts, src/orchestrator/public-health.test.ts, docs/deployed-diagnostics.md
Health status types and projections add lastEnumeratedAtMs. discoveryDeferred remains visible when counters are absent. Documentation defines counter freshness, deferral states, and skipReasons vocabulary.
Sweep retention and completion handling
src/orchestrator/factory.ts, src/orchestrator/sweep-counters.test.ts
Deferred passes update only the deferral marker. Enumerated counts and skip data remain retained. Completion and enumeration timestamps are aligned, and deferred logs use current-pass counts. Tests cover initial deferral, retained measurements, timestamps, and logs.
Diagnostic output and formatting
src/cli/diagnose.ts, src/cli/diagnose.test.ts
CLI diagnostics report count-free deferrals, retained enumeration timestamps, and the latest-pass deferral message. Regression coverage verifies the formatting behavior.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 63245

The change keeps real measurements intact while exposing deferred sweeps, but a mixed-version CLI can produce an awkward diagnostic when the enumeration timestamp is unavailable, and the public wording should more clearly distinguish completed deferrals from completed enumerations. The PR is mergeable with explicit owner follow-up on these bounded issues.

Review hold — Major: publish the measurement timestamp with the retained counts. Reviewed exact head 5c82ac5627389eb9c6587e0790c77edc48ae0265 at 2026-08-24T00:54Z.

Separating the deferral marker from the arithmetic prevents zeroing the last enumeration, but the retained counts still lose their time coordinate. #reconcileReadyIssues() advances lastCompletedAtMs on every deferred pass, while #recordReadinessSweepOutcome() now leaves the old counts in place. The public payload therefore pairs arbitrarily old candidates / dispatched / skipped with a fresh completion timestamp. A consumer can see that the newest pass deferred, but cannot tell whether the retained measurement is one interval or four days old — exactly the distinction this health surface needs to expose.

This also makes the contract internally contradictory: src/types.ts says lastCompletedAtMs identifies the pass the counts describe, and docs/deployed-diagnostics.md first says it dates the counts, then says the retained counts are explicitly not from that pass.

Keeping lastCompletedAtMs moving is correct for the existing stall derivation. The fix is a separate timestamp owned by the same atomic count snapshot (for example lastEnumeratedAtMs / countsMeasuredAtMs), updated only when a pass actually enumerates and projected through the authenticated/public/CLI surfaces. Tests should pin that it advances on enumeration and remains unchanged across multiple deferrals. Until then the values survive but their freshness is unknowable, so this is not merge-ready.

There are also two unresolved exact-head Codex P2 threads (the deferred completion log mixes zero current counts with retained skip reasons; the docs direct read-failed / dispatch-failed to an error class the success path clears). Each needs a worded disposition and resolution.

…stamp

Review hold on #359, and correct. Separating the deferral marker from the
arithmetic stopped a deferred pass zeroing the last enumeration, but left the
retained counts with no time coordinate: `#reconcileReadyIssues` advances
`lastCompletedAtMs` on every settled pass including a deferred one, while the
counts now stay put. So the payload paired arbitrarily old
`candidates`/`dispatched`/`skipped` with an ever-fresh completion stamp, and a
reader could see that the newest pass deferred but not whether the measurement
was one interval or four days old — the freshness this surface exists to expose.

It also made the contract contradict itself: `types.ts` said `lastCompletedAtMs`
identified the pass the counts describe, and the docs said both that and the
opposite two paragraphs later.

`lastEnumeratedAtMs` is now part of the same atomic snapshot as the counts,
written only when a pass actually enumerates, and projected through the
authenticated status, the public health record and `factory diagnose`. Equal to
`lastCompletedAtMs` on a daemon sweeping normally; where they differ, the gap is
exactly how stale the counts are. The recorder takes the caller's completion
stamp rather than reading the clock again, so on an enumerating pass the two
cannot drift apart by a tick — which is what makes the equality assertable.

`lastCompletedAtMs` still moves on deferral, unchanged: the #295/#296 stall
derivation reads it against `lastStartedAtMs`, and freezing it would report a
daemon correctly deferring to another owner as hung after ten intervals.

Two codex P2s on the same head, both real:

- The completion log drew `skipReasons` from the retained snapshot while drawing
  the counts from the current report, so a deferred pass printed `skipped: 0`
  beside a non-empty breakdown — a line contradicting its own arithmetic, on the
  surface a local operator reads. It now derives the breakdown from the report
  it is describing.
- The docs sent `read-failed` and `dispatch-failed` to `lastErrorClass`. Those
  codes count per-item failures an otherwise-successful pass absorbed and
  continued past (#292/#297), and the success path clears `lastErrorClass` — so
  the guidance pointed at a field guaranteed absent in exactly that scenario.
  Reworded to name the container-log lines that do carry the detail, and to note
  that a rising `read-failed` beside `state: healthy` is the #297 signature.

Tests: the enumeration stamp equals the completion stamp on a pass that
enumerated, stays pinned across repeated deferrals while `lastCompletedAtMs`
advances past it, and is absent until a sweep enumerates; plus a recording-logger
test asserting every deferred completion line is internally consistent while the
published surface still retains the real measurement. Verified by ablation —
sourcing the stamp from `lastCompletedAtMs` fails the deferral test on the
equality, and restoring the retained-breakdown log fails the new log test.

All three findings addressed in 079913b — the Major hold, and both exact-head Codex P2s. Dispositions below.


Major (review hold) — publish the measurement timestamp — accepted, fixed

Correct, including the point about the contract contradicting itself. Retaining the counts across a deferral without a stamp of their own left them with no time coordinate: lastCompletedAtMs advances on every settled pass including a deferred one, so the payload paired arbitrarily old counts with an ever-fresh completion time.

lastEnumeratedAtMs is now part of the same atomic snapshot as the counts — written only when a pass actually enumerates, replaced with them, never independently — and projected through the authenticated status, the public health record, and factory diagnose.

One implementation detail worth flagging: #recordReadinessSweepOutcome takes the caller's completion stamp rather than reading the clock again. On an enumerating pass lastEnumeratedAtMs and lastCompletedAtMs therefore describe the same instant exactly and cannot drift by a tick — which is what makes expect(lastEnumeratedAtMs).toBe(lastCompletedAtMs) a real assertion instead of a tolerance.

Reading it:

stamps equal daemon sweeping normally; counts are current
stamps differ the gap is the staleness of the retained measurement
stamp absent nothing has enumerated yet

lastCompletedAtMs still moves on deferral, per your note — the #295/#296 derivation reads it against lastStartedAtMs, and freezing it would report a correctly-deferring daemon as stalled after ten intervals.

Contract contradiction resolved: types.ts now says lastEnumeratedAtMs — not lastCompletedAtMs — dates the counts, and docs/deployed-diagnostics.md says the same thing once instead of twice in opposite directions.

Codex P2 — deferred completion log mixes current zeroes with a retained breakdown — accepted, fixed

Real, and worse on the surface it lands on: this is the line a local operator reads, and it printed skipped: 0 beside a non-empty skipReasons. The log now derives the breakdown from report.skipped — the pass it is actually describing — so every line is internally consistent, while the published surface still retains the real measurement. Both halves are asserted.

Codex P2 — docs direct read-failed/dispatch-failed to a cleared error class — accepted, fixed

Also real. Those codes count per-item failures an otherwise-successful pass absorbed and continued past (#292/#297), and the success path clears #readinessReconcileLastErrorClass — so the guidance pointed at a field guaranteed absent in exactly the documented scenario.

Reworded: those two codes now name the container-log lines that do carry the detail ([factory] relayfile shed a ready-issue read…, [factory] skipped a work unit whose dispatch failed…), state that lastErrorClass describes a pass that failed as a whole, and note that a rising read-failed beside state: healthy is the #297 shedding signature.


Verification

New tests: the enumeration stamp equals the completion stamp on an enumerating pass; stays pinned across repeated deferrals while lastCompletedAtMs advances past it; is absent until a sweep enumerates; and a recording-logger test asserting every deferred completion line is internally consistent.

Ablated, each caught by exactly one test:

ablation fails
source the stamp from lastCompletedAtMs the deferral test, on the equality
restore the retained-breakdown log the new log test, on {…} to deeply equal {}
restore the single-record write (previous round) both deferral tests

npm run build and npm run featuremap:check clean. Full suite 2081 passed, 1 skipped, with one unrelated failure worth naming rather than hiding:

FactoryLoop > keeps the live heartbeat fresh while draining a blocking live event burst
ENOTEMPTY: directory not empty, rmdir '/var/…/factory-live-heartbeat-burst-3nw1J4'

A mkdtemp teardown race, #342 family. It passes alone, and src/orchestrator/factory.test.ts is not in this branch's diff at allgit diff origin/main -- src/orchestrator/factory.test.ts is empty, since the assertion updates went out with #358. Flagging it because a temp-dir rmdir race is the kind of thing that gets re-run into invisibility; if it recurs it belongs on #342 rather than here.

CI running on 079913b.

(Bot status on this head: CodeRabbit rate-limited — its plan allows one included review per hour and #358 consumed it, so it has not reviewed this PR. cubic is neutral — monthly line limit exhausted until 1 September. Codex reviewed and is the source of the two P2s above. Reading the check list alone would suggest more review coverage than exists.)

Hygiene re-read at exact head 079913b045acb502b7545fe2015e2fc2172841b0 (2026-08-24T01:16Z): the Major is fixed by lastEnumeratedAtMs living in the same snapshot as the counts, advancing from the caller’s exact completion stamp only on enumerating passes, and remaining pinned across repeated deferrals while lastCompletedAtMs advances. Both Codex P2s are fixed and their threads have worded dispositions plus resolution. Manual exact-head review found no new finding; all five CI jobs are green per job.

Correction: exact head is 63245e25632203784d3a4b3794dd50cba0420fb6 (2026-08-24T01:38Z).

The exact-head Codex P2 is accepted, fixed, answered in words, and resolved. Count-free diagnostics now say that nothing has enumerated successfully and attribute lease deferral only to the latest pass; a direct regression forbids the old every-pass claim.

Local verification: focused CLI 28/28, build clean, feature-map check clean, full suite 2083 passed and 1 skipped, diff check clean.

5060-5075: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Update the stale "dated by lastCompletedAtMs" claim in this docstring.

Lines 5063-5066 say the retained counts stay "dated by lastCompletedAtMs, which is the honest reading." The new paragraph directly below (5068-5075) explains why that is no longer true: lastCompletedAtMs advances on a deferred pass while the retained counts do not, which is exactly why enumeratedAtMs was added.

Consider this sequence: pass 1 enumerates at T1 (counts + enumeratedAtMs = T1, lastCompletedAtMs = T1). Pass 2 defers at T2 (lastCompletedAtMs = T2, counts unchanged). Pass 3 throws. At that point the retained counts are still from T1, but the old paragraph's claim implies they are "dated by lastCompletedAtMs" = T2, which is wrong.

Update the first paragraph to say the retained counts are dated by enumeratedAtMs, not lastCompletedAtMs, so the two paragraphs agree.

✏️ Suggested wording fix
-   * Only successful passes reach here: a pass that threw has no report, and
-   * inventing zeroes for it would publish "found nothing" for a sweep that

-   * `lastCompletedAtMs`, which is the honest reading.

Inline comments:
In `@src/cli/diagnose.ts`:
- Around line 356-362: Update the discoveryDeferred counted-message branch in
the readiness diagnostic so the “measured …” clause is included only when
lastEnumeratedAtMs is present; otherwise begin directly with the deferral
explanation, avoiding the undefined timestamp placeholder and duplicate dash.

In `@src/orchestrator/sweep-counters.test.ts`:
- Around line 398-435: Capture completedAtMs from the first status observed
after deferClaims is enabled, inside the deferred-pass wait, so any intervening
enumerating pass cannot make the test compare against a stale pre-toggle value.
Update the readinessReconcile test around deferClaims and preserve the existing
assertions comparing lastEnumeratedAtMs and lastCompletedAtMs against that
deferred baseline.

In `@src/types.ts`:
- Around line 317-326: The public health contract in src/types.ts lines 317-326
must state that counters remain absent until an enumerating sweep completes,
distinguishing this from pass completion or deferred discovery. Update the
corresponding wording in docs/deployed-diagnostics.md lines 119-126, including
Lines 105-107, to distinguish “no enumerating sweep” from “no completed sweep”;
no other behavior changes are needed.

the counted-deferral branch, providing candidates, dispatched, skipped,

output and the measured <instant> wording, alongside the existing count-free
coverage.

In `@src/orchestrator/factory.ts`:
- Around line 5060-5075: Update the docstring paragraph describing retained
counts so it identifies enumeratedAtMs, rather than lastCompletedAtMs, as their
timestamp; keep the surrounding explanation and deferred-pass behavior
unchanged.

In `@src/orchestrator/public-health.test.ts`:
- Around line 794-799: Extend the noCounts assertions in the swept projection

Exact-head disposition and review request for 990da0eb8abcc71075a9a91579c99cdef1ef895a (2026-08-24T01:58Z).

All four exact-head findings are accepted, fixed, answered in words, and resolved.

  • a failed pass now clears an older deferral marker while preserving the last real measurement;
  • legacy counted status without lastEnumeratedAtMs no longer renders measured —;
  • the deferral test captures its baseline only after deferral is observable, removing the 50ms race;
  • public types and deployed docs distinguish an enumerating sweep from any completed pass.

Verification: focused diagnose/sweep suites 40/40; failure-marker ablation fails and restored test passes; build and feature-map checks clean; full suite 2085 passed / 1 skipped; git diff --check clean.

@github-actions[bot] I completed a focused review of exact head 990da0eb8abcc71075a9a91579c99cdef1ef895a.

P3 — Update the remaining count-timestamp comments.
src/orchestrator/factory.ts Line 5069 says retained counts are dated by lastCompletedAtMs. This is no longer true after this change. lastCompletedAtMs advances on deferred passes. lastEnumeratedAtMs dates the retained count snapshot.

The same old terminology remains in src/types.ts Line 234 and src/orchestrator/public-health.ts Line 205. The nearby text correctly explains the new behavior, but these headings still call the values the “last completed sweep” counts. Use “last enumerating sweep” consistently.

The implementation otherwise correctly retains the atomic measurement snapshot, clears stale deferral attribution after a failed pass, projects the measurement timestamp through public health and diagnostics, and handles legacy count records in the CLI. git diff --check is clean.

@khaliqgant I reviewed exact head 990da0eb8abcc71075a9a91579c99cdef1ef895a.

I confirmed the four reported fixes. The state transitions, public health projection, wire normalization, CLI output, and regression tests are consistent.

I found one documentation-only issue:

  • P3 — Correct the timestamp statement in #recordReadinessSweepOutcome. In src/orchestrator/factory.ts, the comment above #recordReadinessSweepOutcome says retained counts are “dated by lastCompletedAtMs.” This is now false after a deferred pass. lastCompletedAtMs advances on deferral, while lastEnumeratedAtMs dates the retained count snapshot. Update this sentence to name lastEnumeratedAtMs.

Addressed the remaining CodeRabbit P3 wording findings from comments 5389843986 and 5389844743 at exact head 580f234. The internal snapshot doc, public-health helper, status/public type headings, and per-field comments now consistently say “last enumerating sweep” and date retained counts with lastEnumeratedAtMs; legitimate references to lastCompletedAtMs remain only where they explain deferred-pass completion semantics. This is comment-only and npm run build plus git diff --check are clean. @coderabbitai review @codex review

@khaliqgant The exact-head review of 580f234831569349010abcafda5373c5a1ad4145 confirms the P3 wording corrections.

src/orchestrator/factory.ts, src/orchestrator/public-health.ts, and src/types.ts now consistently identify the count snapshot as the last enumerating sweep. The comments correctly date retained counts with lastEnumeratedAtMs.

The remaining lastCompletedAtMs references describe deferred-pass completion and stall detection. They do not claim to date retained counts.

git diff --check is clean. No new findings.

@github-actions[bot] I reviewed exact head 580f234831569349010abcafda5373c5a1ad4145.

P3 — Correct the remaining “completed sweep” labels for count data.
docs/deployed-diagnostics.md Line 72 still describes candidates, dispatched, and skipped as “The last COMPLETED sweep’s arithmetic” and says that the fields are absent until a sweep completes. A deferred pass completes without enumerating. The fields instead describe the last enumerating sweep and are absent until one enumerates.

The same outdated terminology remains in src/cli/diagnose.ts Line 330 and Line 335. The diagnosis output says “Last completed sweep,” although formatSweepOutcome() can render retained counts from an earlier enumerating pass after the latest pass deferred. Rename these labels to “last enumerating sweep” or equivalent terminology.

The timestamp comments in src/orchestrator/factory.ts, src/orchestrator/public-health.ts, and src/types.ts are consistent. git diff --check is clean.

Addressed exact-head CodeRabbit P3 comment 5389973439 and the failed package job at new head 2e83441. The deployed-diagnostics example, CLI verdict label, helper doc, and absent-count wording now consistently say “last enumerating sweep” / “no sweep has enumerated.” The package failure was a genuine test synchronization flaw, not a runtime failure: the test waited only for durable phase dispatching, which is written before fleet.spawn() starts, so CI could perform takeover early and correctly receive ownership lost before spawning. The test now signals entry into the actual fleet spawn before takeover, pinning the late-placement branch it claims to test. Validation: exact race 5/5, diagnose 29/29, build, and diff check. @coderabbitai review @codex review

@github-actions[bot] I reviewed exact head 2e834415415f58bede2ea23b24410917ca331e4c.

The updated test now waits for entry to HangingSpawnFleetClient.spawn() before lifecycle takeover. This removes the prior race with the earlier dispatching persistence step.

The test still verifies the late-placement release and lateSpawnPlacementsReleased counter. The diagnostic terminology changes remain consistent with the last enumerating sweep model.

git diff --check is clean. No new findings.

@khaliqgant I reviewed exact head 2e834415415f58bede2ea23b24410917ca331e4c.

The P3 terminology correction is complete. The CLI and deployed diagnostics now use “last enumerating sweep” and correctly describe count-free status as no completed enumeration.

The package-test synchronization fix is correct. The test now waits until HangingSpawnFleetClient.spawn() starts before the second owner takes over the lifecycle. It therefore tests the late-placement path and no longer races the earlier durable dispatching write.

git diff --check is clean. No new findings.

Both exact-head Codex P2 findings are fixed and answered at ab5fe9c: marker-only docs scope lease contention to the latest pass, and unstamped deferred count trios are rendered as legacy/unattributable rather than measurements.

@github-actions[bot] I reviewed exact head ab5fe9cbd363b95d094b00c72ea74c4ae778e737.

The legacy deferred-counter handling is correct. formatSweepOutcome() no longer presents an unstamped deferred count trio as a last enumerating measurement.

The public-health projection preserves discoveryDeferred independently from the count snapshot. The CLI output remains consistent for count-free deferrals, retained measurements, and legacy deferred records.

git diff --check is clean. No new findings.

@khaliqgant I reviewed exact head ab5fe9cbd363b95d094b00c72ea74c4ae778e737.

The two Codex P2 fixes are correct.

  • Marker-only documentation limits lease contention to the most recent pass.
  • formatSweepOutcome() labels a deferred count trio without lastEnumeratedAtMs as legacy and not attributable to an enumerating sweep.
  • The focused tests cover both cases.
  • The public-health projection and type documentation remain consistent with this behavior.
  • git diff --check is clean.

No new findings.

Holding on one live P2. The fix itself is right and I want it — this is the bug that made tonight's diagnosis a 40-minute stakeout.

(Reposting: my earlier comment was lost to a GraphQL rate limit, so this is via REST.)

Correction to the framing, because it matters for how we merge

You wrote that #358 was squash-merged "while I was pushing it, so the merge captured only the first commit." I checked, and that is not what happened:

  • GET /pulls/358/commits lists exactly one commit, 0a1b81e6.
  • I merged with -f sha=0a1b81e6 — an expected-head guard. Had your second commit been pushed, the head would have moved and GitHub would have rejected the merge with a 409. It merged cleanly.

So nothing was captured-and-dropped; the commit had not reached the PR yet. No criticism — from your side the outcome looked identical. But if merges here could swallow a concurrent push I would change how I merge, so it is worth both of us knowing the guard holds.

Why I want this fix

A deferred pass settles successfully in ~1s having enumerated nothing, and #358 let its zeroes overwrite the last real sweep. Measured in production tonight — twelve consecutive spaced reads:

candidates: 0  dispatched: 0  skipped: 0  discoveryDeferred: "sweep-in-flight"  lastDurationMs: 1010

It took a 5-minute-interval watcher over ~40 minutes to catch one non-deferred sample, and that sample was decisive:

candidates: 27  dispatched: 0  skipped: 27
skipReasons: { "not-ready": 21, "parked-dependency": 1, "dispatch-failed": 5 }

That killed the discovery hypothesis and located the fault. Your fix makes that reading routine.

The blocker — codex P2 at public-health.ts:249

"Do not turn rejected counter trios into 'never enumerated'." When a health record carries discoveryDeferred alongside a partial or invalid trio, the checks discard the unusable counts but keep the deferral marker, and formatSweepOutcome() then reports it as never-enumerated.

That is the same ambiguity class this whole PR exists to remove, one layer down: "the data was unusable" rendering as "it did not look." Those are different facts and a reader acting on the second would chase discovery — which is precisely the wrong branch I nearly took tonight off twelve deferred zeroes.

Fix it or decline it with reasoning; a reasoned decline is fine if you think the state is unreachable, but say why a corrupted trio cannot co-occur with the marker. If you fix it, the honest rendering is a third state — unusable/unknown — not silently collapsing into either neighbour.

Per-job green already at ab5fe9cb (5/5) and mergeable: clean, so this thread is the only thing outstanding.

Sequencing note: factory-dispatchfail-0824 is building dispatchFailureReasons on lane/dispatch-failure-reasons, also off current main, touching public-health.ts / types.ts / sweep-*. Yours should land first. Flag any conflict shape you see and I will sequence them.

Exact head 921b191f3b91fc9c2d8087766490f9390f887085. Please re-review the complete current diff. This head preserves a distinct unusable-count sentinel when normalization rejects a supplied readiness counter trio.

The unusable-count state is correct.

  • sweepOutcome() detects incomplete and invalid counter trios.
  • It removes unusable counters and preserves discoveryDeferred.
  • It publishes enumerationCountsInvalid: true for the rejected snapshot.
  • formatSweepOutcome() renders this state as not attributable. It does not report that no sweep enumerated.
  • The public-health test verifies the rejected deferred snapshot and its normalization round trip.
  • The CLI test verifies the distinct diagnostic output.
  • git diff --check is clean.

No new findings.
