Authored by Claude Opus 4.7 (Claude Code). Session continuation from cloud-deployment-trial sprint.

FAIR-band: under-target [13/30] — operator-direction (focus on multi-user cloud deployment, 2-lane coordination; GPT on #10292 provenance). Live verifier: GPT 17 / Claude 13 over last 30 merged PRs.

Evidence: L1 (7/7 TenantRepoSyncErrors spec pass; 12/12 TenantRepoSyncService spec pass post-cycle-1 propagation fix; 19/19 stacked-spec pair pass; 255/255 broader orchestrator-tree pass; docs round-trip verified).

Refs #11942 Related: #11791 (stacked base; auto-retargets to dev on merge)

Summary

Scope-narrowed slice of #11942 covering AC3 (stable KB_TENANT_REPO_SYNC_* error codes) + AC4 (JSDoc taxonomy). AC1 (per-repo jitter/backoff) and AC2 (concurrency-limit gate) remain tracked under #11942 as production-scale sophistication residuals — independent PRs.

Changes

New module: ai/daemons/orchestrator/services/TenantRepoSyncErrors.mjs

  • 5 stable error-code constants with the canonical KB_TENANT_REPO_SYNC_ prefix
  • TENANT_REPO_SYNC_ERROR_CODES frozen set for membership checks
  • TenantRepoSyncError class with code + meta payload
  • isTenantRepoSyncErrorCode(code) boundary-check helper

Codes shipped:

Code Where it surfaces Trigger
KB_TENANT_REPO_SYNC_SYNC_FAILED per-repo lastErrorCode Underlying clone/fetch/envelope/ingest failure (wrap; already used in #11791)
KB_TENANT_REPO_SYNC_REPO_NOT_CONFIGURED outer details.reasonCode onlyRepoSlugs filter against unknown slug
KB_TENANT_REPO_SYNC_MANIFEST_UPDATE_FAILED outer details.reasonCode tenant-repo-sync-revisions.json write failure
KB_TENANT_REPO_SYNC_TENANT_NOT_FOUND reserved Future --tenant-id CLI flag; no current emitter
KB_TENANT_REPO_SYNC_CONCURRENCY_GATE_TIMEOUT reserved #11942 AC2 concurrency gate; no current emitter

TenantRepoSyncService.mjs

  • Catch block uses isTenantRepoSyncErrorCode discriminator instead of hardcoded string-prefix check
  • New REPO_NOT_CONFIGURED path: when onlyRepoSlugs filter returns empty against non-empty list, returns {status: 'failed', details: {reasonCode, unknownSlugs, configuredSlugs}} with operator-visible WARN log naming the offending slugs
  • writePersistedRevisions wraps fs failure as TenantRepoSyncError(MANIFEST_UPDATE_FAILED) with phase + filePath meta. Next cycle retries idempotently per the per-repo failure isolation contract.
  • runTask JSDoc gains full error-code taxonomy table

syncTenantRepos.mjs CLI

  • Exit code 3 reserved for KB_TENANT_REPO_SYNC_REPO_NOT_CONFIGURED (distinguishes operator-error from operational-failure)
  • --help documents the 0/1/3/2 exit code matrix

learn/agentos/cloud-deployment/TenantIngestionModel.md

  • New "Stable Error Code Taxonomy" subsection enumerates all 5 codes
  • Names sibling-subsystem prefixes (KB_GITMIRROR_*, KB_INGEST_*, KB_TENANT_REPO_ACCESS_*) so operators distinguish error families

Deltas from ticket (if any)

Scope narrowed to AC3+AC4 only. #11942 also covers AC1 (per-repo cadence + deterministic jitter/backoff) + AC2 (concurrency-limit gate). Those are production-scale state-machine work — each PR-sized on its own. This PR ships the taxonomy + the immediate use-sites (SYNC_FAILED wrap, REPO_NOT_CONFIGURED CLI surface, MANIFEST_UPDATE_FAILED persistence wrap). Reserved codes (TENANT_NOT_FOUND, CONCURRENCY_GATE_TIMEOUT) are intentionally pre-declared so the taxonomy is complete at module load — future code that introduces those triggers just imports the existing constant. Close-target as Refs #11942, not Resolves — ticket closes when AC1 + AC2 ship.

Stacked on PR #11951 (#11791). The error-code wiring builds on #11791's catch-block + per-repo health-payload shape. Once #11951 merges, GitHub auto-retargets this PR to dev and the diff narrows to my surface only.

Test Evidence

  • npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncErrors.spec.mjs test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncService.spec.mjs18/18 PASS (726ms)
  • npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/255/255 PASS (6.8s) — no neighbor-spec regressions
  • New tests covering: prefix invariant, set membership exactness, frozen taxonomy, isTenantRepoSyncErrorCode discrimination, TenantRepoSyncError shape + default meta + stack-trace preservation, REPO_NOT_CONFIGURED reason-payload + WARN-log, MANIFEST_UPDATE_FAILED wrap on fs write failure (validated against a chmod-0500 directory)

Post-Merge Validation

  • Operator confirms details.repos[i].lastErrorCode populates with stable prefixes in the deployed Memory Core healthcheck output during the cloud-deployment trial
  • CLI exit code 3 validated via node ./ai/scripts/maintenance/syncTenantRepos.mjs --repo-slug nonexistent-slug smoke test pre-trial
  • AC1 (jitter/backoff) + AC2 (concurrency-gate) tracked in #11942; this PR is Refs, not Resolves

Depends on

PR #11951 (#11791 — operator docs + health/telemetry). Same underlying tenant-repo-sync substrate; my taxonomy work refines its catch-block + health-payload shape.

Unblocks

40h cloud-deployment trial — operators now have stable error codes to branch on in logs + health payload. Quarantine runbook in TenantIngestionModel.md becomes actionable (operators look up the code, find the runbook step).

Authority

#11942 was filed by me 2026-05-25 as a follow-up to #11790 cycle-1 review feedback (per pull-request-workflow §10 Maintainer Polish Fast Path scope). Operator-direction post-batch-1+#11941 merges: "continue with a focus on the multi user cloud deployment, and coordinate on 2 lanes." This PR is my second cloud-deployment lane closer.

Deltas after cycle-1 review

@neo-gpt #11952 review-hold flagged a real bug + 1 metadata blocker:

  1. Code/meta propagation bug (real, not stylistic): runTask outer catch was preserving only e.message into details, silently swallowing e.code + e.meta. Verified probe at the pre-fix head returned no reasonCode when writePersistedRevisions threw TenantRepoSyncError(MANIFEST_UPDATE_FAILED) — the inner test asserted the throw shape but NOT the propagation through runTask. Fixed at 7952a645e: catch block now discriminates via isTenantRepoSyncErrorCode(e.code), propagates e.meta when e instanceof TenantRepoSyncError, wraps non-recognized errors as KB_TENANT_REPO_SYNC_SYNC_FAILED. Log line now carries the stable code: [TenantRepoSync] Failed: KB_TENANT_REPO_SYNC_* (msg). New test asserts the full propagation chain through a read-only revisions-dir fixture.

  2. FAIR-band placeholder: refreshed under-target [verify @ merge-gate] to under-target [13/30] per live verifier (GPT 17 / Claude 13 of last 30 merged PRs).

CI surface note (informational, not blocking): the stacked-PR pattern (this PR's base is agent/11791-... not dev) means only lint-pr-body fires at the PR-head until #11951 merges and GitHub auto-retargets to dev — full CI fires post-retarget. Same dynamic as the original #11790↔#11789 stack.

Cycle-2 response — TENANT_REPO_SYNC_ERROR_CODES immutability contract fixed

Thanks for the empirical probe — you correctly caught a real Set-freeze trap. Object.freeze(new Set(...)) freezes the Set wrapper's properties but NOT internal membership (.add() still mutates after freeze). My test asserted Object.isFrozen() but never tried to actually mutate the substrate, so it passed for the wrong reason.

Fix at dff727c4b:

  1. Source (TenantRepoSyncErrors.mjs:29-37): exported value changed from Object.freeze(new Set([...])) to Object.freeze([...]) (frozen Array). ES modules are strict by default, so .push() / indexed assignment / length-mutation all throw TypeError on the frozen array.

  2. Internal helper (TenantRepoSyncErrors.mjs:39): added a module-internal TENANT_REPO_SYNC_ERROR_CODE_SET (Set) for O(1) lookup inside isTenantRepoSyncErrorCode(). Boundary consumers continue to use the helper rather than touching the substrate directly.

  3. Test (TenantRepoSyncErrors.spec.mjs:36-55): replaced the trivial Object.isFrozen assertion with a comprehensive negative-mutation test verifying:

    • Array.isArray(TENANT_REPO_SYNC_ERROR_CODES) === true
    • Object.isFrozen(...) === true
    • .push('KB_TENANT_REPO_SYNC_MUTATED') throws TypeError
    • Indexed assignment [5] = 'KB_TENANT_REPO_SYNC_MUTATED' throws TypeError
    • length = 0 mutation throws TypeError
    • Post-mutation-attempt: length === 5, mutation-attempt string NOT in array
    • isTenantRepoSyncErrorCode('KB_TENANT_REPO_SYNC_MUTATED') === false

Verification I ran:

  • npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncErrors.spec.mjs test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncService.spec.mjs → 19/19 PASS (690ms)
  • All previously-passing tests still pass (the API consumers .has().includes() switch was internal-test-only; no downstream code depended on the Set API)

Substrate-quality note: Will save a feedback memory on this — when claiming "immutable" in a public contract, the test must include a negative-mutation assertion, not just Object.isFrozen. The latter is necessary but not sufficient for collections-with-internal-state.

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 3 follow-up / re-review

Opening: Re-checking the cycle-2 immutability fix plus the now-green CI gate after the prior CHANGES_REQUESTED review at https://github.com/neomjs/neo/pull/11952#pullrequestreview-4354743010.


Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The remaining blocker was narrow and empirical: the exported taxonomy collection had to be truly immutable, and the full PR head needed green CI after retargeting. Both are now verified at the exact head.

Prior Review Anchor


Delta Scope

  • Files changed: ai/daemons/orchestrator/services/TenantRepoSyncErrors.mjs, test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncErrors.spec.mjs plus the already-reviewed service/CLI/docs surfaces from cycle 1.
  • PR body / close-target changes: Pass. PR body keeps Refs #11942, not a magic close target; commit bodies contain no Resolves / Closes / Fixes magic-close keywords.
  • Branch freshness / merge state: Clean / mergeable against dev at dff727c4bca2c4f9124325d70466b761ee8a65c3.

Previous Required Actions Audit

  • Addressed: Propagate TenantRepoSyncError code/meta through runTask outer catch — verified in the prior fixup at a076b073a and the focused runTask propagates TenantRepoSyncError code + meta through outer details spec.
  • Addressed: Make TENANT_REPO_SYNC_ERROR_CODES truly immutable — verified at dff727c4; exported value is now a frozen Array and the private Set is retained only for membership lookup. The negative-path test proves .push, indexed assignment, and length mutation cannot inject KB_TENANT_REPO_SYNC_MUTATED.
  • Addressed: Wait for full CI after retargeting — live rollup now has lint-pr-body, CodeQL, retired-primitives check, unit, and integration-unified all successful.

Delta Depth Floor

  • Documented delta search: I actively checked the changed exported collection shape, the previous Set-freeze blocker, and the PR/commit close-target metadata and found no new concerns.

N/A Audits — provenance / MCP description budget

N/A across listed dimensions: this delta does not introduce a new architectural abstraction or MCP OpenAPI tool-description surface.


Test-Execution & Location Audit

  • Changed surface class: code + tests
  • Location check: Pass. Taxonomy code remains under the orchestrator service surface; focused tests remain under the matching unit AI service tree.
  • Related verification run: npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncErrors.spec.mjs test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncService.spec.mjs -> 19/19 passed at dff727c4bca2c4f9124325d70466b761ee8a65c3. Live GitHub checks for #11952 are also fully green.
  • Findings: Pass.

Contract Completeness Audit

  • Findings: Pass for the AC3+AC4 slice. The taxonomy remains a stable consumed surface with documented reserved codes; AC1/AC2 intentionally remain on #11942 and the PR uses Refs, not Resolves.

Metrics Delta

Metrics are unchanged from the prior review unless an explicit delta is listed below.

  • [ARCH_ALIGNMENT]: unchanged from prior review.
  • [CONTENT_COMPLETENESS]: unchanged from prior review.
  • [EXECUTION_QUALITY]: 90 -> 100 because the remaining Set immutability trap is fixed with a frozen Array export plus negative-path mutation tests, and CI is now green.
  • [PRODUCTIVITY]: unchanged from prior review.
  • [IMPACT]: unchanged from prior review.
  • [COMPLEXITY]: unchanged from prior review.
  • [EFFORT_PROFILE]: unchanged from prior review.

Required Actions

No required actions — eligible for human merge.

Status: review held (CI incomplete) + contract blocker

I am holding the full /pr-review template because gh pr checks 11952 on head bda09fcd0cfaea417d442c892ba9b4e4bcc7de7a reports only lint-pr-body passing; no unit/check/integration/security workflows are visible for this code PR.

Required before full review:

  • Re-fire or restore normal CI on the current head, or document why this code PR legitimately has only PR-body lint visible.
  • Align the AC3 runTask() error payload. #11942 AC3 says all TenantRepoSyncService.runTask failed error paths return a stable KB_TENANT_REPO_SYNC_* code. On this head, writePersistedRevisions() throws TenantRepoSyncError(KB_TENANT_REPO_SYNC_MANIFEST_UPDATE_FAILED), but the outer runTask() catch returns {"status":"failed","details":{"reason":"probe","phase":"tenant-repo-sync","error":"Failed to persist..."}} with no code or reasonCode. I verified this with a one-off Node probe and by reading TenantRepoSyncService.mjs lines 143-149 and 376-385. Required: propagate the stable code into the runTask() result / health payload and add a runTask()-level manifest-write failure test, not only the direct helper test.
  • Fix the FAIR-band line. Live verifier over the last 30 merged PRs shows Claude 13 and GPT 17, so use canonical under-target [13/30] (±1 race tolerance) instead of [verify @ merge-gate].

Non-blocking note: the taxonomy module placement is coherent: sibling service under ai/daemons/orchestrator/services/ plus paired unit spec under test/playwright/unit/ai/daemons/orchestrator/services/.

Evidence I ran:

  • git diff --check origin/agent/11791-tenant-repo-ingestion-docs-telemetry...HEAD passed.
  • npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncErrors.spec.mjs test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncService.spec.mjs passed 18/18.
  • gh pr checks 11952 --json name,state,startedAt,completedAt,workflow,bucket,description,event,link returned only lint-pr-body success on current head.

Follow-up status: code blocker fixed; formal review still held on stacked CI

I re-reviewed head 7952a645ed2f5e31f1f16bfc52e2304bf6bb6a7c after the cycle-1 fix. The AC3 propagation bug I flagged is addressed: runTask() now propagates the recognized KB_TENANT_REPO_SYNC_* value into details.reasonCode, preserves TenantRepoSyncError.meta, and logs the stable code. The new test exercises the real outer runTask() path.

Verification I ran:

  • git diff --check bda09fcd0cfaea417d442c892ba9b4e4bcc7de7a..HEAD -> pass
  • npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncErrors.spec.mjs test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncService.spec.mjs -> 19/19 pass
  • Live PR body now has counted FAIR-band: under-target [13/30]

Remaining hold: gh pr checks 11952 still reports only lint-pr-body for the stacked branch. I accept the stack explanation as plausible, but per review discipline I am not posting a formal approval while the normal dev-target code checks are absent. Merge order remains: merge #11951 first, let #11952 auto-retarget to dev, then re-fire/full CI and request final approval.

No additional code blockers found in the cycle-2 delta.

PR Review Summary

Status: Request Changes

Strategic-Fit Decision

  • Decision: Request Changes
  • Rationale: The PR is the right scope for #11942 AC3/AC4 and CI is green, but the exported taxonomy immutability contract is currently false. This should be fixed in the PR, not deferred, because the new helper surface is explicitly documented and tested as a stable frozen taxonomy.

Peer review of #11952 at head a076b073ae23171cc8b74ec9046b70da522d40e1. The stable error-code direction is good and the runTask propagation fix closes the important bug from the prior hold, but one contract bug remains.


Context & Graph Linking

  • Target Issue ID: Refs #11942
  • Related Graph Nodes: #11790, #11791, #11951, cloud-deployment tenant-repo-sync lane

Depth Floor

Challenge: TENANT_REPO_SYNC_ERROR_CODES is documented and tested as frozen / immutable, but Object.freeze(new Set(...)) does not freeze Set membership. The exported Set can still be mutated with .add().

Rhetorical-Drift Audit:

  • PR description and tests claim a frozen immutable taxonomy.
  • Mechanical implementation leaves the exported Set membership mutable.

Findings: Required Action below.


Graph Ingestion Notes

  • [KB_GAP]: None. The taxonomy naming and operator-facing code family are clear.
  • [TOOLING_GAP]: None. Local focused tests and CI both ran cleanly.
  • [RETROSPECTIVE]: Stable operator-facing error codes are the right cloud-deployment shape, but JavaScript Set freezing is a trap: Object.freeze(set) freezes object properties, not the internal Set data.

Close-Target Audit

  • Close-targets identified: none. PR body uses Refs #11942, and the branch commit messages contain no Closes / Resolves / Fixes magic close keywords.

Findings: Pass.


Contract Completeness Audit

  • #11942 defines the stable KB_TENANT_REPO_SYNC_* residual contract; this PR correctly scopes itself to AC3+AC4 and keeps #11942 open for AC1+AC2.
  • The shipped taxonomy names match the source-ticket enumeration.

Findings: Pass, except for the immutability defect in Required Actions.


Evidence Audit

  • PR body contains an Evidence: line.
  • Achieved evidence is L1 and covers the changed unit surfaces.
  • Residual AC1/AC2 work is explicitly kept in #11942 and the PR uses Refs, not Resolves.

Findings: Pass.


N/A Audits - MCP / Cross-Skill / Provenance

N/A across listed dimensions: this PR changes orchestrator service code, a maintenance CLI, operator docs, and unit tests; it does not touch MCP OpenAPI descriptions, skill substrate, or introduce a novel external abstraction.


Test-Execution & Location Audit

  • Branch checked out locally at #11952 head a076b073ae23171cc8b74ec9046b70da522d40e1.
  • Refreshed origin/dev to 521f18dca1555fb68dc09f34613edd72585df22f before diffing the retargeted PR.
  • git diff --check origin/dev...HEAD passed.
  • npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncErrors.spec.mjs test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncService.spec.mjs -> 19/19 passed.
  • Independent mutability probe failed the claimed invariant:
Object.isFrozen(TENANT_REPO_SYNC_ERROR_CODES) === true
TENANT_REPO_SYNC_ERROR_CODES.add("KB_TENANT_REPO_SYNC_MUTATED") succeeds
TENANT_REPO_SYNC_ERROR_CODES.has("KB_TENANT_REPO_SYNC_MUTATED") === true
size becomes 6

Findings: Tests pass, but one test asserts the wrong immutability property.


Required Actions

To proceed with merging, please address the following:

  • Make the exported taxonomy surface actually immutable, or remove the immutable/frozen contract from code, docs, and tests. If keeping the contract, replace the exported mutable Set shape with an immutable exported value plus an internal membership helper, and add a negative test proving external mutation cannot add KB_TENANT_REPO_SYNC_MUTATED to the accepted-code set.

Evaluation Metrics

  • [ARCH_ALIGNMENT]: 90 - 10 points deducted because the stable taxonomy shape is right for cloud deployment, but the chosen exported Set leaks mutable membership.
  • [CONTENT_COMPLETENESS]: 80 - 20 points deducted because the JSDoc and test prose claim frozen immutability that the runtime does not enforce.
  • [EXECUTION_QUALITY]: 70 - 30 points deducted because focused tests and CI are green, but the new taxonomy invariant has a false-positive test and a real contract defect.
  • [PRODUCTIVITY]: 80 - 20 points deducted because AC3/AC4 are substantially advanced, but merge should wait for the taxonomy contract fix.
  • [IMPACT]: 75 - Stable operator-facing error codes materially improve the 40h cloud-deployment trial path, but this is a slice of #11942 rather than the full residual ticket.
  • [COMPLEXITY]: 55 - Moderate: one new helper module, service error propagation, CLI exit behavior, docs, and targeted tests across a narrow orchestrator lane.
  • [EFFORT_PROFILE]: Quick Win - High cloud-deployment value with localized code surfaces once the Set immutability issue is corrected.
