feat(health): publish the sweep's candidate/dispatched/skipped counts (#355) - #358
Conversation
…#355) A readiness sweep on the live container completed in 843ms with `state: healthy`, `consecutiveFailures: 0`, no `lastError`, `fleetControlPlane: closed`, `eventListener: subscribed` and a free dispatch slot — and dispatched none of seven eligible issues in routed repos. Every published subsystem read green through a total dispatch outage, because none of them measures what the sweep actually did. The sweep's own completion log already carries the three numbers that split this in half: - `candidates > 0` — it SAW those issues and REJECTED them, so the bug is in eligibility evaluation. - `candidates == 0` — it NEVER PULLED them, so the bug is upstream in discovery/ingestion. Two different bugs with two different owners, and the line separating them goes to container stdout, which does not reach `wrangler tail`. This puts it on the evidence surface instead. `readinessReconcile` now carries `candidates`, `dispatched` and `skipped` from the last *completed* sweep — the same tense as `lastDurationMs`, dated by `lastCompletedAtMs`, left untouched by a pass that failed. They travel as a group, all present or none, so nothing can publish one pass's `dispatched` beside another's `candidates`. Absent and zero are deliberately different. A sweep that ran and found nothing publishes `0`; a daemon that has not finished a sweep publishes nothing at all. That distinction is the whole point — the projection uses `optionalCount`, not `counter()`, which would have collapsed both into `0` — and it is what tells "never ran" from "ran and found nothing". Two fields make a zero readable rather than merely visible: - `skipReasons` splits `skipped` by `FACTORY_SWEEP_SKIP_REASON_CODES`, a closed fourteen-value vocabulary recorded at the skip site, never matched out of the operator text — a rename would otherwise collapse every bucket into `other`. `dispatch-terminal` and `dispatch-retry-limit` are the two that never clear on their own. `#dispatchBlockReason` returns its code alongside its message for the same reason. - `discoveryDeferred: 'sweep-in-flight'` names the sweep that returned immediately because another process held the discovery lease. It completes healthy in milliseconds having enumerated nothing, so on counts alone it is indistinguishable from a sweep that queried every repo and found no work — opposite diagnoses, identical `candidates: 0`. Counts only, by construction, per the existing `fleetControlPlane` and #315 occupant rules: no issue keys, paths or titles. `skipReasons` is the only field whose KEYS arrive from a remote record, and an object key publishes as readily as a value, so the reader rebuilds it from its own copy of the vocabulary and folds anything unrecognised into `other` — which keeps the parts summing to `skipped` rather than silently dropping a bucket. `factory diagnose` renders both, and the final "dispatching: readinessReconcile is healthy" verdict — the line that was true and useless tonight — now ends with the last sweep's arithmetic. Tests: a must-fire/must-not-fire pair over a real live daemon and a real sweep (never a hand-set status field), plus a CONTROL asserting each expectation throws on the other's fixture, so a hard-wired counter cannot satisfy both. Also pinned: the periodic reconcile as well as the startup backfill, absent-until-swept, the skip-reason split, the deferred sweep, and redaction of the serialized record. Verified by ablation — removing the periodic recorder, the backfill recorder, the deferred field, or the absent/zero distinction each fails exactly one of them, and hard-wiring the counters fails the control specifically.

Merging. This is the instrument the whole incident has been missing, and it is built to the standard I asked for plus one thing I did not think to ask for. Zero vs absent, done properly. This was the requirement most likely to be quietly fudged and you nailed it: And the comment explaining why — "Deliberately NOT The leak vector you closed. Rebuilding the skip breakdown key by key from this module's own enum copy, rather than passing through whatever keys arrive, stops an unknown value reaching the unauthenticated surface by being used as an object key. That is a real vector and not an obvious one — the surface stays numbers-only even if an upstream skip reason is added later.
On the declined thread: I checked your reasoning rather than inheriting CodeRabbit's acceptance of it, because the objection landed near the ambiguity I care most about. A lease deferral reporting zero candidates is safe specifically because Bar cleared: 5/5 green at Next it needs to reach production — publish, bump, deploy — and then one |

#359) * fix(health): a deferred sweep must not erase the last real measurement 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. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> * fix(health): date the retained counts with their own measurement timestamp 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.

#361) * feat(health): publish why a dispatch attempt failed, as a bounded enum `skipReasons` (#358) told us the live container skips 27 candidates every sweep and that 5 of them are `dispatch-failed` — with the control-plane breaker closed, the fleet agent online and `readinessReconcile` healthy. That bucket is a count. It says the sweep got all the way to dispatching and dispatch threw; it does not say what threw, and the message that would say so goes to the daemon's stdout, which does not reach the deployed container's operator. This is the second level of the same breakdown, built the way #358 built the first: - `dispatchFailures` is the total, published as a zero once a sweep completes. `skipReasons` omits zero counts, so on that field alone "every dispatch succeeded" and "this producer has never heard of dispatch failures" are the same absence — and 0.1.72 is in production being exactly the second thing. - `dispatchFailureReasons` splits it by a closed vocabulary. Counts only, keys rebuilt from this side's own list rather than taken from the record, unknown codes folded into `other` so the parts still sum. The code is recorded at the skip site from the thrown value, never parsed back out of the operator-facing `reason` — a reworded message would silently empty a bucket. Classification follows the cause chain, because `contextualError` and the control-plane guard both rethrow wrapped. When nothing named matches, the *phase* that threw is the answer: `unclassified-gate` / `-triage` / `-dispatch`. A unit that failed in triage never reached the fleet, and on a surface carrying no messages the phase is the only thing left that still says who should look. #292's own tests now pin those codes: the `TypeError: fetch failed` case from #291 is `unclassified-triage`, not a fleet fault. `dispatchFailures` is deliberately NOT joined to the all-or-nothing candidates/dispatched/skipped trio. Requiring it would drop a 0.1.72 daemon's whole sweep block — deleting the counters that are currently the only view of the outage. Tests drive the real writer: a live daemon whose real dispatch really throws. Ablated five ways — absent coerced to zero, zero dropped as uninteresting, unknown codes dropped instead of folded, the skip site not classifying, and the incoming string used as an object key — each caught by the assertion that names it.
