feat(diagnostics): make a deployed Factory able to say why it is not dispatching (#295)

[khaliqgant]

Closes #295.

A deployed Factory could not be asked why it was not dispatching. During the 2026-08-19/20 outage the field naming the cause existed the whole time and was unreachable for ~10 hours; recovering it required minting a new Worker secret, which is a production write. This PR makes the answer reachable with no credential and no write.

1. The non-sensitive signals, on the public surface

The daemon now writes a redacted projection of its loop heartbeat as heartbeat.health (publicHealthFromHeartbeat, src/orchestrator/public-health.ts), for the container to serve verbatim on /healthz:

{
  "ok": true, "status": "degraded", "stale": false, "loopStatus": "running",
  "degradedSubsystems": ["readinessReconcile"],
  "reason": "dispatch-gating subsystem not healthy: readinessReconcile",
  "readinessReconcile": {
    "state": "stalled", "consecutiveFailures": 0, "failureThreshold": 3,
    "intervalMs": 60000,
    "lastStartedAtMs": 1787224595805, "lastCompletedAtMs": 1787224535802,
    "inFlightMs": 4620000, "missedPasses": 77,
    "lastErrorClass": "TimeoutError"
  },
  "eventListener": { "state": "subscribed" }
}

• consecutiveFailures — read 7 then 8 during the outage while /healthz said ok: true.
• lastErrorClass — through the existing telemetryErrorClass allowlist from fix(orchestrator): skip per-item dispatch failures instead of aborting the run-once pass (#292) #293. That allowlist had been copied into two files; it is now one module (src/observability/error-class.ts) that factory.ts, hosted/orchestrator.ts and the projection all import. No second implementation.
• lastStartedAtMs / lastCompletedAtMs / inFlightMs / missedPasses — the subject of the second half of [factory] A deployed Factory has no operator-reachable diagnostics: the field naming an outage is unretrievable by design #295. Their relative order is the only thing that distinguishes a hung pass from a healthy idle one.

2. state: "stalled", derived rather than written

#scheduleReadinessReconcile re-arms only inside sweep.finally(...), and a hang takes neither the success nor the failure path — so a wedged pass leaves state: healthy, consecutiveFailures: 0 and lastError: undefined in place forever. The state is now derived against the clock: an in-flight pass older than ten sweep intervals is stalled, in factory.status() and on the public block alike.

Ten intervals, not two: #36 measured a legitimate post-boot reconcile at 61 minutes while the Relayfile mirror hydrated. lastCompletedAtMs ships alongside so "first pass since boot, still hydrating" stays distinguishable from "was fine for hours, then wedged".

I did not add the sweep watchdog that comment 3 of the issue raises. It changes dispatch behaviour rather than observability, and it is #296's subject; this PR is the diagnostics half.

3. Should ok go false? No — and here is why

ok stays a pure liveness bit. /healthz is the Cloudflare Container ping endpoint (pingEndpoint = 'localhost/healthz' in the factory-cloud Worker), so a non-200 there is a verdict the platform acts on: it recycles the container. That would destroy the in-memory evidence of the wedge and restart the 61-minute cold-start hydration — a degradation that erases its own cause and can loop.

So the amber goes where no platform reads it: status (ok/degraded/unknown), degradedSubsystems, and reason. A monitor alerts on status != "ok" with no lifecycle side effect. The issue's objection — "a liveness endpoint that cannot go amber is not much of a signal" — is answered by the endpoint going amber in a field that cannot restart the box. Covered by a test (keeps ok true for a live process while status goes amber).

4. factory diagnose --deployed <url>

The command that goes in a lane brief. No credential needed; exits non-zero when the instance is not dispatching (same contract as factory canary). Run against a stub serving the observed 2026-08-20 record:

$ factory diagnose --deployed http://127.0.0.1:8791
factory diagnose — http://127.0.0.1:8791
  reachable            : yes (HTTP 200)
  liveness (ok)        : true
  status               : degraded
  loop                 : running, heartbeat 12s old
  degraded subsystems  : readinessReconcile
  readinessReconcile:
    state              : stalled
    consecutiveFailures: 0 (threshold 3)
    lastErrorClass     : —
    cadence            : 1m 0s
    pass in flight     : 1h 17m (77 missed passes)
    lastStartedAt      : 2026-08-20T11:16:35.805Z
    lastCompletedAt    : 2026-08-20T11:15:35.802Z
  eventListener        : subscribed
  evidence             : not read — no operator token supplied — pass --token or set FACTORY_EVIDENCE_TOKEN

verdict: not dispatching: the readiness sweep is stalled — one pass has been in flight for 1h 17m (77 missed passes at 1m 0s cadence). The loop only re-arms when a sweep settles, so a hung pass stops dispatch permanently.
exit=1

--token (or FACTORY_EVIDENCE_TOKEN) additionally pulls /evidence for the free-text lastError. Everything is pulled through the Worker: the container is private-networked with no sshd, so nothing here assumes shell access. Against an instance older than this change the command reports "state strings only (instance predates #295)" rather than a false green.

--json prints the same diagnosis for scripting.

MUST-NOT-FIRE: no sensitive value crosses the public surface

lastError is dependency-controlled free text that routinely carries provider prose, filesystem paths and URLs with credentials in the query string. It stays behind /evidence. The public record is built by construction — every field named, every number coerced, every string a closed enum or through the allowlist, nothing spread — so a field added upstream cannot leak by default.

Proof: two tests feed a lastError containing a path, a URL and a token and stuff the same text into lastErrorClass, then assert none of it appears in the published record:

• src/orchestrator/public-health.test.ts → keeps provider text, filesystem paths, URLs and tokens off the public surface
• src/orchestrator/factory.test.ts → publishes the failure count and error class without the message that names a path (asserts the authenticated readinessReconcile.lastError does still contain the path, and the published block does not)

Also covered: the free-text eventListener.reason is dropped; hostile non-numeric counters are coerced; a remote /healthz record is re-normalized before it can reach a terminal.

Fail-first

a. The projection, against a naive pass-through baseline (what the surface does today — trust state, spread the record). 8 of 10 failed on the mechanism:

 ❯ src/orchestrator/public-health.test.ts (10 tests | 8 failed)

 × keeps provider text, filesystem paths, URLs and tokens off the public surface
AssertionError: expected '{"schemaVersion":1,"ok":true,"status"…' not to contain '/srv/agent-workforce'
Received: {... "lastError":"ENOENT: no such file or directory, open '/srv/agent-workforce/.relay/workspace-key'
          while POSTing https://relay.internal.example.com/v1/workspaces/ws_9f2?token=sk-live-abcdef0123456789" ...}

 × derives stalled from lastStarted > lastCompleted past the stall threshold
AssertionError: expected { state: 'healthy', …(5) } to match object { state: 'stalled', …(2) }
-   "inFlightMs": 4620000,
-   "missedPasses": 77,
-   "state": "stalled",
+   "state": "healthy",

 × keeps ok true for a live process while status goes amber
AssertionError: expected 'ok' to be 'degraded'

b. The daemon tests, with the mechanism reverted (state back to last-write-wins, inFlightMs dropped, health block published raw):

 × publishes the failure count and error class without the message that names a path
AssertionError: expected { schemaVersion: 1, ok: true, …(4) } to match object { ok: true, status: 'degraded', …(2) }
-   "degradedSubsystems": [ "readinessReconcile" ],
+   "degradedSubsystems": [],
-   "status": "degraded",
+   "status": "ok",

 × reports a hung sweep as stalled while every settled field still reads healthy
AssertionError: expected 'healthy' to be 'stalled'

Three seconds of real hang, and the pre-change surface reports healthy throughout — the exact defect.

c. The allowlist, widened by one field (lastError added next to lastErrorClass) — both must-not-fire tests fail, in the projection and in the daemon:

 × keeps provider text, filesystem paths, URLs and tokens off the public surface
 × publishes the failure count and error class without the message that names a path
AssertionError: expected '…' not to contain '/srv/agent-workforce'

d. The CLI, before the command existed: 9/9 failed (Unknown factory action: diagnose).

All restored and green afterwards: npm test → 98 files, 1849 passed, 1 skipped; npm run build and npm run featuremap:check clean.

Review round 1 (73a2e3a)

14 bot findings, 13 accepted. Every one of them was the same defect class as the issue itself — a surface reporting green when it does not know — which is a fair sign the reviewers read the intent and not just the diff.

finding	outcome
P1 frozen snapshot: ageMs/stale are stamped at write time, so a container serving a dead daemon's heartbeat stayed green forever	fixed — the instance's liveness verdict (HTTP status / ok, recomputed per request on its own clock) now outranks the block. Not recomputed against the reader's clock: skew would read as stall
P1 the fleet control-plane circuit was absent from the record, though an open circuit fails every spawn	fixed — third redacted subsystem: state, counters, retryAtMs; never its lastError, which names the broker socket path
P1 a hung startup backfill recorded no timestamps, so the derivation had nothing to derive from	fixed — it now stamps start and settle. Timestamps only; failure accounting stays with the reconcile loop that owns the threshold and the #297 allowlist
P1 an incomplete block (no readiness subsystem) read as dispatching: true	fixed — cannot tell, non-zero
P2 event-driven short-sleep mode answers /healthz at the Worker without probing the container, so the block is unreachable there	fixed both sides — the CLI detects that response and reports cannot tell pointing at /evidence; the exclusion is now stated at the passthrough in factory-cloud#40 with a test pinning it
P2 a listener still starting counted as healthy	fixed — only subscribed/polling are dispatch-capable, and only on an instance whose readiness loop is running (a bounded factory loop is not supposed to hold a subscription)
P2 intervalMs: 0 → instant stalled and missedPasses: Infinity (JSON null)	fixed — a cadence must be positive; an unusable one falls back and is not republished
P2 new Date(1e300).toISOString() throws and aborts the diagnosis	fixed at the boundary (ECMA-262 time-value limit) and in the renderer
P2 C1 control characters survived the terminal sanitizer	fixed — C0 and C1 both stripped
P2 deps.env ignored when reading FACTORY_EVIDENCE_TOKEN	fixed — env threaded through the parser
P3 the documented /healthz example could not have been produced by the code (ageMs is always 0; epochs did not cohere)	fixed — rewritten against one reference instant
P3 TELEMETRY_ERROR_CLASS_PATTERN rejects the bare names Error and Exception	declined here. Real, but that regex is the #293 allowlist guarding every telemetry surface, and widening a security-relevant pattern as a side effect of a health-endpoint PR is how allowlists stop being allowlists. The suggested form also admits 1Error; the narrow fix is ^(?:[A-Za-z][A-Za-z0-9]{0,63})?(?:Error|Exception)$. Offered as its own one-line PR

Two more came from running the built CLI against stubs rather than from a unit test — both the same wrong-problem failure the command exists to prevent (8cbbde3): a response the Worker answered without probing the container was rendered as "instance predates #295", inviting an upgrade of a Factory that is fine, and phase printed twice. Absence of the block says nothing about the instance's version when nobody asked the instance.

One thing I found while re-reading the P1 fix (fd67d24): a container in booting/rendering-config/preflight answers ok: false and 503 exactly as a wedged one does, so the new liveness short-circuit told anyone diagnosing a starting instance that their Factory process was gone. The phase was already in the response; a bootstrap phase now gets its own "not yet" verdict naming the cold-start hydration, rather than sending an operator to the wrong problem during the window where that costs most.

Each fix has its own test, and the startup-backfill one was verified by mutation — reverting the stamping fails it with expected 'healthy' to be 'stalled'. Suite after this round: 1866 passed, 1 skipped; featuremap check clean.

Note for whoever reviews this: two green checks are not reviews. CodeRabbit reports "Review rate limited" — it never started (re-requested). Devin Review reports "Full review skipped: trial expired and no credits remaining". The findings above came from codex (3) and cubic (11); CI itself is green on all five jobs.

Review round 2 (ec4cb33) — CodeRabbit's first actual pass

Its earlier green checks were rate limits, not reviews. Once it ran it filed 10, of which 9 are fixed and 1 declined. Same family as round 1: a diagnostic asserting more than it knows.

The one that matters most: the projection ran unguarded on the heartbeat write path. #writeLoopHeartbeat is called from places with no surrounding try/catch, and that file is what the crash reaper and /healthz read to decide the daemon is alive — so a throw in new code would have failed every heartbeat write and made a healthy daemon look wedged. The diagnostic causing the outage it exists to explain. Both call sites are now guarded, the failure is logged, and the block is omitted rather than half-written — which is itself legible, since factory diagnose reports a missing block rather than a false green. Pinned by src/orchestrator/health-projection-guard.test.ts, which mocks the projection to throw (the honest way to test a defence against a condition the code does not currently produce).

The rest:

finding	outcome
live: false on any non-200, so a gateway 404 / auth-proxy 401 / LB 502 produced "the instance reports itself not live… the Factory process is gone" about a container never asked	fixed — only a 503 or an explicit ok is the instance speaking; anything else is cannot tell: the endpoint answered HTTP n and carried no Factory health
a status the block didn't report coerced to unknown and printed "a subsystem is degraded"	fixed — not knowing ≠ knowing something is wrong
every non-200 from /evidence blamed the token, sending operators to rotate a working credential on a 404 or 5xx	fixed — 401/403 blame the token, 404 says the route isn't exposed, 5xx says the endpoint errored
the unknown-argument error echoed the value, so factory diagnose <url> <token> put a credential on stderr and into CI logs	fixed — reports the position, never the value
the CLI tests omitted a hermetic env, so an ambient FACTORY_EVIDENCE_TOKEN broke the suite (live because I threaded deps.env through earlier in round 1)	fixed — verified with the token exported: 1 failed before, 19 pass after
the reader accepted intervalMs: 0 and negative durations, undoing the invariant the writer enforces two functions away	fixed
the docs claimed every field is "a closed enum or a coerced number" — not true of the booleans, the array, or the bounded text; two fences lacked a language	fixed
replace the telemetryErrorClass pattern with a finite list of known class names	declined. The channel is real (a compromised dependency controlling Error.name could push ~60 bounded alphanumerics), but a finite list collapses our own dispatch error classes to Error the day they're added — silent signal loss, which is the surface #295 exists to remove. The channel also isn't created here: it's the #293 allowlist already feeding four telemetry call sites, and a public-only variant would fork the definition of "safe class name". Offered as its own cross-surface PR instead

Suite: 1874 passed, 1 skipped. Both declines in this PR are about the same shared file, and I'd rather fix it once, for every surface, than twice, differently.

Not in this PR

• The container pass-through, which lives in AgentWorkforce/factory-cloud: opened as factory-cloud#40, not merged, not deployed. It is two lines (health: parsed.health in publicHeartbeat()) plus the policy comment and tests — that repo's /healthz projection is documented as carrying subsystem state only, and [factory] A deployed Factory has no operator-reachable diagnostics: the field naming an outage is unretrievable by design #295 is a deliberate, argued reversal of the counters-and-timestamps half of that rule, so it is reviewed on its own rather than slipped past the guard test. Merge order: this PR first; older Factories publish no block and the field is simply absent.

  Note the block is served at heartbeat.health, and factory diagnose reads it there (and accepts a top-level health).

• A stable operator credential for /evidence (proposal 2 in the issue). That is a factory-cloud secret-lifecycle change. This PR reduces its urgency by moving the signals an operator actually needed onto the unauthenticated surface, but does not close it.

• The sweep watchdog — [factory] An unbounded readiness-reconcile sweep stops the loop permanently and silently #296.

Re-evaluate heartbeat age before declaring dispatch healthy

When the daemon stops updating its heartbeat but the container still serves the last file, this trusts the embedded health snapshot and can return dispatching: true indefinitely. #writeLoopHeartbeat creates that snapshot with nowMs === updatedAtMs, so its ageMs is initially zero and stale false; because this path neither recalculates age from updatedAtMs nor treats the outer /healthz HTTP status/ok as authoritative, a stale heartbeat remains green precisely when the daemon has died or wedged.

Useful? React with 👍 / 👎.

[khaliqgant]

Valid, and the worst of the three — fixed in 73a2e3a.

You are right about the mechanism: #writeLoopHeartbeat builds the block with nowMs === updatedAtMs, so ageMs: 0 / stale: false are frozen into the file and stay green for as long as the container keeps serving it.

I did not fix it by recomputing age from updatedAtMs against the reader's clock — that trades one wrong answer for another, since a laptop diagnosing a container in another region would report skew as stall, and this command exists to be trusted during an outage. Instead the instance's own verdict now outranks the snapshot: container/entrypoint.mjs calls isDeploymentHealthy() on every request, computing staleness from updatedAtMs against the container clock, and answers ok: false + HTTP 503. diagnoseDeployedFactory records that as live, and verdictFor short-circuits on live === false before reading any subsystem:

not dispatching: the instance reports itself not live (HTTP 503). Its loop heartbeat is stale or
the Factory process is gone, so any health block it still serves describes the last write, not
the present.

Test: believes the container liveness verdict over a frozen health snapshot — 503 + ok: false with a perfectly green block attached, expecting a non-zero exit. It fails on the pre-fix code (expected +0 not to be +0).

I also documented the write-time stamping on FactoryPublicHealth.stale so the next reader does not have to rediscover that these two fields are not freshness.

Treat listeners that are still starting as non-dispatching

During live startup, before #startLiveSubscription installs the subscription, #eventListenerStatus() returns starting, yet this predicate only degrades not-listening. The resulting health record has status: "ok", and verdictFor consequently reports dispatching: true even though no event listener is registered; startup work can be lengthy, so require a dispatch-capable state such as subscribed or polling before reporting green.

Useful? React with 👍 / 👎.

[khaliqgant]

Agreed — fixed in 73a2e3a.

starting is exactly the window before #startLiveSubscription installs the subscription, and reporting green with no listener registered is the same false green this issue is about. The predicate now requires subscribed or polling; everything else is dispatch-gating.

One qualification I added: only on an instance whose readiness loop is actually running. A bounded factory loop reports eventListener: not-listening and readinessReconcile: not-running, and is not supposed to hold a subscription — faulting it would make a correct run look broken. So the listener gate applies when readinessReconcile.state !== "not-running".

Tests: treats a listener that is still starting as not yet dispatch-capable and does not fault the listener on an instance that is not running live.

Validate remote timestamps before formatting them

For human-readable output, a malformed or hostile health response containing a finite but out-of-range timestamp such as 1e300 passes normalizePublicHealth and reaches this call, where toISOString() throws RangeError: Invalid time value. That aborts rendering and replaces the requested diagnosis with a generic CLI error; bound timestamps to the JavaScript Date range or render invalid values as unknown.

Useful? React with 👍 / 👎.

[khaliqgant]

Confirmed and fixed in 73a2e3a — new Date(1e300).toISOString() throws RangeError: Invalid time value, and before the fix the CLI exited 1 with a generic error instead of the diagnosis it was asked for.

Fixed at the boundary rather than only at the renderer: normalizePublicHealth (and the write-side projection) now run every *AtMs field through a timestamp() coercion that requires |v| <= 8.64e15, the ECMA-262 time-value limit — out-of-range values are dropped, so the field is simply absent rather than a number no one can format. Durations (intervalMs, inFlightMs, lastDurationMs) keep the plain finite check, since they are not instants.

formatInstant also guards (Number.isNaN(instant.getTime()) → unknown), belt and braces: a renderer asked to explain an outage must never be the thing that throws.

Tests: drops timestamps outside the representable Date range, drops an out-of-range timestamp written into the heartbeat itself, and renders an out-of-range remote timestamp as unknown instead of aborting.

You are right that an open circuit gates dispatch just as hard as a failing sweep: #fleetControlPlane fails spawns and resumes fast while open, and the health record said nothing about it. It is now a third redacted subsystem in the projection and in degradedSubsystems:

"fleetControlPlane": { "state": "open", "consecutiveFailures": 4, "failureThreshold": 3, "retryAtMs": 1787229180000 }

open and half-open both count as gating — half-open is one probe away from either answer, and neither is admitting work normally. Its lastError does not cross: a roster probe failure names the broker socket path (connect ECONNREFUSED /run/relay/broker.sock), which is precisely what must stay behind /evidence. The test asserts that path does not appear in the published record.

Tests: reports an open fleet control-plane circuit as dispatch-gating, does not fault a closed fleet control-plane circuit.

Valid — same one codex raised, fixed in 73a2e3a. new Date(1e300).toISOString() throws RangeError: Invalid time value, and the CLI exited 1 with a generic error instead of the diagnosis.

Fixed at the boundary as well as the renderer: normalizePublicHealth and the write-side projection run every *AtMs field through a timestamp() coercion bounded by the ECMA-262 time-value limit (8.64e15), so an out-of-range value is dropped rather than published as a number nothing can format. Durations keep the plain finite check — they are not instants.

formatInstant renders unknown for an invalid date rather than —, only because — already means "not recorded" in that output and the two are worth telling apart: absent field vs. a value the instance sent that cannot be a time. Happy to switch it to — if you would rather have one symbol.

Tests: drops timestamps outside the representable Date range, renders an out-of-range remote timestamp as unknown instead of aborting.

[khaliqgant]

You are right about the behaviour, and I am not changing it in this PR — deliberately.

Confirmed: the pattern needs at least one character before Error/Exception, so Error and Exception both fail it. Error lands on 'Error' via the fallback and is indistinguishable; a class named exactly Exception is reported as Error, which is a real (if small) misreport against the documented intent.

Why not here: this regex is the allowlist that shipped in #293 and it now guards every telemetry surface plus this new unauthenticated one. The brief for #295 was explicit about reusing it rather than writing a second one, and widening a security-relevant pattern as a side effect of a PR about health endpoints is how allowlists quietly stop being allowlists. It also deserves its own fail-first test rather than riding along here.

One note if someone picks it up: the suggested ^[A-Za-z]?[A-Za-z0-9]{0,63}(?:Error|Exception)$ widens more than intended — with the first group empty, 1Error and 999Exception now pass, so a numeric-leading name becomes admissible. The narrow form is:

/^(?:[A-Za-z][A-Za-z0-9]{0,63})?(?:Error|Exception)$/u

which admits the two canonical bare names and nothing else new. Happy to open that as a one-line PR against src/observability/error-class.ts with its own coverage if you want it — say the word.

Practical impact meanwhile: an error whose class is exactly Exception reads as Error on the public block, which still tells an operator "this failed" and still routes them to /evidence for the message. Nothing in the outage this PR addresses turns on it.

CI note — one flaky failure, not from this branch.

Run 32399445066 failed the package job on 8cbbde3 with:

FAIL src/orchestrator/factory.test.ts > FactoryLoop PR babysitter >
     routes and coalesces only the owned PR review/check/comment events with metadata-only fencing
Error: Test timed out in 5000ms.
Tests  1 failed | 1865 passed | 1 skipped (1867)

That test is untouched by this PR. Evidence it is the repo's 5s-default flake under a loaded runner rather than a regression here:

• main is currently red the same way. Run 32387158162, on this branch's base commit 3f7c01f, fails package with Test timed out in 5000ms — a different test in the same file.
• The same job passed on the two earlier commits of this branch (runs 32398611298, 32397142041).
• Locally the named test passes 3/3 in isolation, and the full suite is 1866 passed / 1 skipped.
• Re-running the failed job: green. All five CI jobs now pass.

I have deliberately not raised testTimeout here. Papering over it would be a repo-wide settings change unrelated to #295, and the flake predates this branch — it deserves its own issue and its own look at why these live-mode tests sit so close to a 5s bound on CI hardware.

Cover the reason sanitization and the degradedSubsystems allowlist in normalizePublicHealth.

normalizePublicHealth is the only path that applies boundedText to reason, and reason is the one free-text field that reaches a terminal. The code comment at src/orchestrator/public-health.ts Lines 121-125 records this as a review follow-up about C1 escape introducers. No test pins that behavior.

Add a test at the exact stall threshold.

This test uses 9 intervals, which is below the threshold. derivedReadinessReconcileState compares with strict > against intervalMs * READINESS_RECONCILE_STALL_INTERVALS. If that comparison changed to >=, this test would still pass, because 9 intervals is below the threshold either way.

Render fleetControlPlane in the human report.

FactoryPublicHealth carries fleetControlPlane and normalizePublicHealth populates its state, failure counts and retryAtMs. The human report never prints it, so an operator whose instance is held by an open control-plane circuit sees only status: degraded.

Use a finite allowlist for telemetryErrorClass.

Error.name is writable, and the pattern accepts arbitrary bounded values such as AttackerChosenError. This value can reach unauthenticated /healthz. Replace pattern-based admission with explicit known class names and map all others to Error.

Declining this one, and I want to be precise about which part I am disagreeing with, because the premise is sound.

Agreed: Error.name is writable, this value now reaches an unauthenticated surface, and the pattern admits any bounded [A-Za-z][A-Za-z0-9]{0,63}(Error|Exception). A compromised dependency that controls a thrown error's name could therefore push up to ~60 attacker-chosen alphanumeric characters onto /healthz. That is a real, if narrow, channel and it is worth someone's attention.

Where I differ, on three counts:

1. A finite list of known class names destroys the thing [factory] A deployed Factory has no operator-reachable diagnostics: the field naming an outage is unretrievable by design #295 asked for. The classes that matter here are ours and they are not centrally enumerable — DispatchLifecycleError, the relayfile overload classes, whatever the next subsystem throws — plus Node's own (AbortError, TimeoutError, SystemError) and every dependency's. A list would collapse most of them to Error on the day they are added, which is precisely the "degraded, and nothing else" surface the outage was about. The failure mode of a stale allowlist is silent signal loss, and nobody notices until the next incident.

2. The channel is not created here, and forking it makes it worse. telemetryErrorClass is the fix(orchestrator): skip per-item dispatch failures instead of aborting the run-once pass (#292) #293 allowlist, already carrying class names to the Cloud telemetry surface from IterationReport.skipped[].reason and four call sites in hosted/orchestrator.ts. If arbitrary bounded name values are an exfiltration concern, they are a concern on those paths too — and the fix belongs at the source, applied once, with the fix(orchestrator): skip per-item dispatch failures instead of aborting the run-once pass (#292) #293 owners in the room. A public-only variant here would mean two divergent definitions of "safe class name", which is how the guarantee quietly stops holding.

3. What actually crosses is tightly bounded. No whitespace, no punctuation, no path separators, no : or / or ., 64 characters, must end in Error/Exception. Every category [factory] A deployed Factory has no operator-reachable diagnostics: the field naming an outage is unretrievable by design #295's must-not-fire list names — provider text, filesystem path, URL, token — is structurally excluded, and the tests feed a lastError containing all four and assert none of it appears.

The brief for this PR was also explicit about reusing the existing allowlist rather than writing a second one, so redesigning it as a rider on a health-endpoint change is the wrong vehicle even if the redesign is right.

Happy to be overruled by a maintainer. If the residual channel should close, I would rather open it as its own PR against src/observability/error-class.ts — covering all surfaces, with a test that a hostile name cannot cross and a decision recorded about what happens to unlisted classes — than land a divergent public-only rule here. Say the word and I will write it.

(Also worth noting for anyone reading the thread: cubic raised a narrower issue with the same regex — it rejects the bare names Error and Exception — which I declined for the same "not in this PR" reason. If that follow-up PR happens, both belong in it.)

@khaliqgant, thank you for the detailed explanation. Your reasoning is clear on all three points.

The shared allowlist point is the strongest one. telemetryErrorClass already feeds IterationReport.skipped[].reason and the hosted/orchestrator.ts call sites. A public-only rule here would create two different definitions of "safe class name" for the same function. That split is worse than the current gap.

The pattern already excludes whitespace, punctuation, path separators, and length beyond 64 characters. This covers the leak categories that /healthz must not expose: provider text, filesystem paths, URLs, and tokens. The residual risk is a bounded alphanumeric string ending in Error or Exception. This is a narrow channel, not the categories #295 was built to block.

I will not insist on a fix in this PR. A single follow-up PR against src/observability/error-class.ts, covering every call site with one test suite, is the correct place for this change and for the bare-Error/Exception case cubic raised.

Learning: In src/orchestrator/factory.ts and src/observability/error-class.ts (Node.js/TypeScript), `telemetryErrorClass` is a shared allowlist function used by both the `#293` Cloud telemetry surface (`IterationReport.skipped[].reason`, `hosted/orchestrator.ts` call sites) and the `#295` unauthenticated `/healthz` public health surface (`readinessReconcileLastErrorClass`). Any change to its class-name admission rule (e.g., replacing the bounded regex pattern with a finite allowlist) must be made once across all call sites in a dedicated PR, not scoped to only the public health path, to avoid divergent definitions of "safe error class name."

CI note 2 — the flake recurred on ec4cb33, again not from this branch.

FAIL src/orchestrator/factory.test.ts > FactoryLoop PR babysitter >
     stops renewing the terminal Slack receipt lease when the daemon is shutting down
AssertionError: expected false to be true
Test Files  1 failed | 98 passed | 1 skipped (100)

Different test from the first occurrence, same signature: exactly one test from this file, a different one each run. This one is a bounded fake-timer spin —

for (let tick = 0; tick < 200 && !mount.receiptWriteEntered; tick += 1) {
  await vi.advanceTimersByTimeAsync(1)
}
expect(mount.receiptWriteEntered).toBe(true)

— which starves when the real async work behind those ticks is slower than the budget on a loaded runner. Same family as the Test timed out in 5000ms occurrence, just showing up as an assertion rather than a timeout.

Checked rather than assumed, because "it's flaky" is the easy answer:

• The named test cannot reach this diff. It starts the factory with mode: 'dispatch-owner', and the live heartbeat — where the health projection is written — is gated on if (live) await this.#startLiveHeartbeat() (src/orchestrator/factory.ts:1131). No live heartbeat, no readiness reconcile scheduling, so none of this PR's runtime paths execute in that test.
• Passes 3/3 locally in isolation; full suite locally is 1877 passed / 1 skipped.
• Re-run of the failed job: green.
• main is red with the same one-test-per-run signature (run 32387158162 on 3f7c01f).

Still not raising testTimeout or widening those spin budgets here — it is a repo-wide change unrelated to #295, and it deserves a look at why these live-daemon and fake-timer tests sit so close to their bounds on CI hardware rather than a bigger number. Happy to file that as its own issue.
