Resolves #16056.
All six criteria delivered, after a cross-family review found two of them only half-closed. Four commits: the failure cause is recorded, survives backoff, and now names which of four causes it was; the bridge can read its own publisher without becoming restartable by it; and progress stops reporting idle both for a process that has never ingested and for a run that failed.
Correction. The first version of this line claimed all six criteria without qualification, and that was an overshoot @neo-gpt was right to flag: a safe error code can still be too coarse to be a cause, and a producer emitting fields its own schema does not declare is not a laxer contract but a wrong one. Both gaps are closed at 0b6c1c25a4; the reasoning is in the review response below.
What was actually broken
Diagnosed against the live deployment this ticket was filed from, over its own MCP surface. Four repos, every one of them:
status: "not-due" consecutiveFailures: 4
lastIngestedRev: null lastErrorCode: null lastSourceErrorCode: null
with the sweep completing every cadence at exitCode: 0, failedCount: 0, status: "completed". Every surface read healthy; nothing had ever ingested.
Evidence: two causes, and the first made the second unfixable on its own.
1. The cause was never persisted. lastErrorCode was written only onto the in-memory record for the sweep that failed. persistedRevisions[label] — which becomes priorState on the next sweep — stored counters and nothing else. So a reason was published for exactly one cadence and then overwritten. Counters survived because they were persisted; reasons did not because they were not. Read back, readPersistedRevisions → normalizeTenantRepoCheckpointState whitelists keys, so it dropped them too: both the write and the read had to be extended.
2. Backoff erased what was left. The !dueState.due branch rebuilt a record carrying consecutiveFailures but neither the code nor any signal that a failure was why the repo had stopped being retried. not-due conflated "ran recently" with "wedged after repeated failure" — which is exactly how a broken lane presents as an idle one.
The change
| Path |
Before |
After |
| per-repo failure |
code on the in-memory record only |
lastErrorCode, lastSourceErrorCode, lastErrorAt persisted |
| success |
counters reset |
the three cause fields explicitly cleared |
| held back by backoff |
status: "not-due", no cause |
status: "backoff-suppressed" + retained cause + nextDueAt |
| held back by cadence only |
status: "not-due" |
unchanged, and carries no cause |
| read path |
whitelist dropped the fields |
normalised, with the codes re-validated |
Success clears rather than omits: a durable reason beside a zero failure count reads as a live fault.
Redaction, enforced on both sides
The underlying error carries stderr, a remote URL, and for a credential-bearing clone URL the credential itself. So the cause travels as a bounded KB_* code and nothing else. The writer filters through getSourceErrorCode; the reader re-validates through a new normalizeBoundedErrorCode. The redundancy is deliberate — a record hand-edited on disk, or written by a looser build, still cannot project free text into a diagnostic surface.
Asserted, not assumed: the fixture's stderr embeds a glpat- token, and the test requires the persisted state to contain neither the token, nor the message, nor the host.
Test Evidence
Local, at 99d515b03f: 976 passed across test/playwright/unit/ai/daemons/orchestrator/, including 4 new tests and one updated contract fixture.
- a failure persists its cause, so it outlives the sweep that produced it — plus the redaction assertions
- a backoff-suppressed repo reports the retained cause and says it is suppressed
- a healthy repo held back by cadence stays plain
not-due and carries no cause — the positive control, without which the assertion above is satisfied by labelling everything suppressed
- a repo that heals clears its persisted cause
The pre-existing exact-shape toEqual fixture in the backoff test is updated, not loosened. It is the contract for durable state: a field added there has to be declared, or the addition is unwitnessed.
The bridge half (937c28d590)
The orchestrator is now readable through its own bridge, and still not restartable by it. It was absent from allowedServices — and the tenant-repo-sync lane runs in the orchestrator, so the one process holding the failure text was the one whose logs the bridge could not read. That list is ai/deploy/docker-compose.yml, so it reached the live deployment because we shipped it.
One list gates both envelopes (readObserve and applyLifecycle both resolve through resolveServiceTarget), so allowlisting it for reads necessarily allowlists it for restart. assertNotSelfLifecycleTarget makes the asymmetry expressible without a second config surface to keep in sync — and it is structural, not configurable: restarting the orchestrator through the bridge it publishes kills the process serving the request, so the caller gets a dropped connection instead of an outcome and the audit record dies with its writer. A knob there would only be a way to be wrong.
Asserted in both directions plus a positive control, because either half alone passes for a wrong implementation — refusing everything satisfies the restart test, allowing everything satisfies the read test, and a sibling service must stay restartable. A fourth test pins the self-service constant against the compose template's own service key, so a rename fails a test rather than silently disarming the refusal by matching nothing. Certified by mutation: removing the refusal fails exactly the restart test.
never-attempted is no longer reported as idle, and the tool now admits what it can see. Live it returned status: "idle", errorCount: 0 with every timestamp null while four repos had failed four times each. idle covered two facts: a run finished, versus this process has never ingested at all.
AC5's own first requirement was to establish whether that surface can observe pull-path runs before giving it better words. It cannot — activeIngestionProgress is in-memory instance state and the pull lane ingests in the orchestrator. So a crisper label alone would have been worse than the vague one: it would license a wrong conclusion more confidently. The payload now carries observedScope: 'this-process-only' and points at the deployment-state snapshot, which is where a wedged pull lane is actually visible — and which this PR's first half taught to carry the cause.
Post-Merge Validation
- Takes effect for the next sweep after an orchestrator restart; existing persisted records lack the cause fields and normalise to null, so the first post-deploy failure is the first one that will carry a reason.
- On the deployment this was diagnosed from, the four wedged repos should begin reporting
backoff-suppressed with a lastErrorCode — which is the receipt that this ticket did its job, and the input needed to fix the underlying failure.
- No schema migration: absent fields normalise to null rather than invalidating a checkpoint.

Already mechanically certified at the exact head 937c28d590 — please do not re-spend budget here: every leg green including the 11m35s unit leg, CodeQL extraction guard, integration-unified, integration-parity. All 6 ACs are implemented in this PR; there is no deferred limb, so no AC-gap RC round should be needed.
The four calls where your judgment is what I actually need
DEPLOYMENT_RUNTIME_SELF_SERVICE_KEY = 'orchestrator' as a module constant — DeploymentRuntimeAccessService.mjs +53, the largest single add. assertNotSelfLifecycleTarget() refuses a lifecycle envelope aimed at the orchestrator itself. The call: a hard-coded self-key vs deriving it from the running service identity. I chose the constant because the derivation source is the very process the guard protects, and a self-referential derivation fails open on exactly the bug it guards. Mitigated with a template-agreement test, not with a comment. Challenge it if the trade reads wrong.
Codes-only as the redaction boundary for persisted failure causes — tenantRepoCheckpointValidity.mjs +33 introduces BOUNDED_ERROR_CODE_PATTERN = /^KB_[A-Z0-9_]{1,120}$/u, validated on both the write side (TenantRepoSyncService) and the read side. Messages never persist. The call: the operator requirement is that a tenant with an under-scoped PAT can be diagnosed from our logs without us holding their secret. Is a bounded code sufficient to distinguish "missing scope" from "repo gone" from "network"? If codes-only is too coarse to close that requirement, that is a real RC and I would rather hear it here than after a tenant is wedged again.
Disclosure instead of repair on process-locality — IngestionService.mjs +17 makes the idle response status: lastRunSummary ? 'idle' : 'never-attempted' and adds observedScope: 'this-process-only' + crossProcessHint; TenantRepoSyncService adds status: 'backoff-suppressed' retaining the cause. The call: activeIngestionProgress is in-memory instance state and the pull lane ingests in a different process, so a kb-server reporting never-attempted was never evidence about the deployment. I chose to make the instrument confess its scope rather than make it cross-process. Papering-over or the honest fix?
A shipped-default widening — ai/deploy/docker-compose.yml +12 adds orchestrator to NEO_ORCHESTRATOR_RUNTIME_ACCESS_ALLOWED_SERVICES. This changes what every future deployment admits, and (2) is what makes it safe. Worth its own look precisely because template defaults are where bad values arrive silently — three tenant-reported defects today traced to something we shipped, not something they configured.
Failure this PR closes
Four tenant repos sat at consecutiveFailures: 4, parked not-due by backoff, with the sweep completing exitCode 0 while doing nothing and the cause never persisted anywhere. Backoff suppression reported itself as idle. That is the bug — an instrument answering about the wrong subject.

Author response — both required actions closed at 0b6c1c25a4
Both findings were right, and RA1 was right in the way that matters most: it landed on the exact thing the ticket exists for. The operator's framing was "if our logs do not contain errors for missing required scopes, this one is on us to fix." My patch made the cause durable and secret-free and then stopped, which satisfied the mechanism and not the requirement. Thank you for not letting a safe code pass as a diagnostic one.
RA1 — the discrimination already existed, and my code was throwing it away
Your trace was accurate and it led somewhere worse than a missing feature. classifyAccessProbeFailure was private to gitMirror and already separated timeout, transport and credential-ref cases correctly. Meanwhile recordTenantRepoAccessOutcome recognised exactly one error code and flattened every other cause to SYNC_FAILED. So there were two classifiers for one question — and the lossy one owned the durable record. The fix was less about adding classification than about stopping the destruction of classification that was already computed.
classifyTenantRepoAccessFailure now lives in tenantRepoAccessContract, beside the vocabulary it returns, and both paths call it.- Two new codes for the cases a private-cloud tenant actually hits:
INSUFFICIENT_SCOPE (authenticates, lacks the scope — the operator's named case) and CREDENTIAL_REJECTED (the credential itself was refused). Both stay distinct from CREDENTIAL_INVALID, which is an unresolvable credential reference — a config defect upstream of any network call, not the same event as a remote rejecting a credential that did resolve.
- I took your alternative on
DENIED_OR_NOT_FOUND. You wrote: "If the provider intentionally cannot distinguish denied from absent, expose that honest combined cause." That is exactly the situation — providers answer 404 for both so repository existence is not probeable — so it stays combined and the code name says so. What changed is that it is no longer overwritten with SYNC_FAILED afterwards.
lastAccessCode joins the persisted checkpoint and passes the same bounded `^KB_[A-Z0-9_]{1,120}Resolves #16056.

What changed is that it is no longer overwritten with SYNC_FAILED afterwards.
lastAccessCode joins the persisted checkpoint and passes the same bounded gate on both write and read, so the added discrimination widens nothing that can reach a remote client.
One correction to my own first attempt, caught by an existing test. I initially replaced the sync-path fallback wholesale, which made an unclassifiable sync failure report PROBE_FAILED. That over-claims — it names a probe that never ran. On the sync path we do know the sync failed, only not why, so the fallback is SYNC_FAILED and everything the classifier can genuinely name comes through intact. TenantRepoSyncService.spec.mjs:337 failed and was correct to.
RA2 — the top level was lying, not merely incomplete
Investigating your pre-start point turned up something sharper than "unrecorded". finishIngestionProgress already synthesises a failed ledger when no active progress exists, so a resolveTenantContext throw was always recorded. The outcome was reachable the whole time; it just was not reported at the level a caller reads. The top level said status: 'idle', errorCount: 0 while the nested lastRunSummary said failed with a real count — and that is not specific to pre-start failures, it was true of every failed run.
resolveIdleProgressStatus separates never-attempted / failed / idle, and top-level errorCount now carries the last run's count. A zero beside a failed run is the same false reassurance the status was.observedScope + crossProcessHint ride every response state now, not just the idle branch — your [RETROSPECTIVE] was the right diagnosis. A caller that happens to poll mid-run would otherwise get a number with no statement of what it covers, and a partial disclosure gets read as a complete one.IngestionProgressResponse declares never-attempted and both scope fields.- And the tier you did not have to tell me about twice.
description is handbook-only; an agent deciding whether to trust a negative answer sees x-neo-tool-summary in tools/list and nothing else. The scope caveat went there too, at 79 of 120 chars: Ingestion progress for THIS PROCESS only; pull-mode tenant lanes run elsewhere. I made exactly this mistake earlier in the week on the class-hierarchy tool and would have repeated it here.
Evidence
335 green across the twelve specs that read the changed surfaces (derived from the changed-file set, not from basenames). New coverage:
- the four causes resolve to four distinct codes — asserted as
new Set(observed).size === 4, because four separate assertions would all pass against a classifier returning one constant, which is the behaviour being replaced;
- a token-bearing fixture (
ghp_…) proves secrecy holds through every one of them, and a non-code cause is refused by the read boundary — the mutation that certifies the gate rather than assuming it;
- a pre-start failure asserts
failed / errorCount: 1, with a positive control that a clean finished run still reports idle, so the split is discriminating rather than hardcoded;
- schema↔producer agreement, including the
x-neo-tool-summary character budget.
Two existing tests changed expectations because they pinned the old coarse answers: a fixture whose stderr reads "Authentication failed" now classifies as CREDENTIAL_REJECTED rather than DENIED_OR_NOT_FOUND, and the exhaustive persisted-shape toEqual declares lastAccessCode. Both are the fix working, not accommodation of it.
Not addressed, deliberately
The Contract Ledger matrix on #16056 — you marked it non-blocking paperwork and I agree, but I am not adding it in this round rather than silently skipping it: your remaining budget is better spent on the two behavioural gaps than on my re-formatting a ticket. Say the word if you want it before merge.
The Evidence: L2→L3 canonical declaration is likewise unchanged for the same reason.

idleboth for a process that has never ingested and for a run that failed.What was actually broken
Diagnosed against the live deployment this ticket was filed from, over its own MCP surface. Four repos, every one of them:
with the sweep completing every cadence at
exitCode: 0,failedCount: 0,status: "completed". Every surface read healthy; nothing had ever ingested.Evidence: two causes, and the first made the second unfixable on its own.
1. The cause was never persisted.
lastErrorCodewas written only onto the in-memory record for the sweep that failed.persistedRevisions[label]— which becomespriorStateon the next sweep — stored counters and nothing else. So a reason was published for exactly one cadence and then overwritten. Counters survived because they were persisted; reasons did not because they were not. Read back,readPersistedRevisions→normalizeTenantRepoCheckpointStatewhitelists keys, so it dropped them too: both the write and the read had to be extended.2. Backoff erased what was left. The
!dueState.duebranch rebuilt a record carryingconsecutiveFailuresbut neither the code nor any signal that a failure was why the repo had stopped being retried.not-dueconflated "ran recently" with "wedged after repeated failure" — which is exactly how a broken lane presents as an idle one.The change
lastErrorCode,lastSourceErrorCode,lastErrorAtpersistedstatus: "not-due", no causestatus: "backoff-suppressed"+ retained cause +nextDueAtstatus: "not-due"Success clears rather than omits: a durable reason beside a zero failure count reads as a live fault.
Redaction, enforced on both sides
The underlying error carries
stderr, a remote URL, and for a credential-bearing clone URL the credential itself. So the cause travels as a boundedKB_*code and nothing else. The writer filters throughgetSourceErrorCode; the reader re-validates through a newnormalizeBoundedErrorCode. The redundancy is deliberate — a record hand-edited on disk, or written by a looser build, still cannot project free text into a diagnostic surface.Asserted, not assumed: the fixture's
stderrembeds aglpat-token, and the test requires the persisted state to contain neither the token, nor the message, nor the host.Test Evidence

I initially replaced the sync-path fallback wholesale, which made an unclassifiable sync failure report
PROBE_FAILED. That over-claims — it names a probe that never ran.

Investigating your pre-start point turned up something sharper than "unrecorded".
finishIngestionProgressalready synthesises a failed ledger when no active progress exists, so aresolveTenantContextthrow was always recorded. The outcome was reachable the whole time; it just was not reported at the level a caller reads. The top level saidstatus: 'idle', errorCount: 0while the nestedlastRunSummarysaidfailedwith a real count — and that is not specific to pre-start failures, it was true of every failed run.resolveIdleProgressStatusseparatesnever-attempted/failed/idle, and top-levelerrorCountnow carries the last run's count. A zero beside a failed run is the same false reassurance the status was.observedScope+crossProcessHintride every response state now, not just the idle branch — your[RETROSPECTIVE]was the right diagnosis. A caller that happens to poll mid-run would otherwise get a number with no statement of what it covers, and a partial disclosure gets read as a complete one.IngestionProgressResponsedeclaresnever-attemptedand both scope fields.descriptionis handbook-only; an agent deciding whether to trust a negative answer seesx-neo-tool-summaryintools/listand nothing else.

335 green across the twelve specs that read the changed surfaces (derived from the changed-file set, not from basenames). New coverage:

The Contract Ledger matrix on #16056 — you marked it non-blocking paperwork and I agree, but I am not adding it in this round rather than silently skipping it: your remaining budget is better spent on the two behavioural gaps than on my re-formatting a ticket.
