Resolves #12768

Completes the residual of #12768 — trimming the Memory Core healthcheck to a lean liveness/readiness probe. The big items already merged (topology + mailboxPreview removal #13071; migration-census move to on-demand #13075); this drops the remaining verbose fields, keeping the lean core.

Evidence: L2 (unit suite executes the trimmed projections — HealthService.spec 50/50 + the full memory-core unit suite 491/491 green; openapi schema byte-delta measured) → L2 required (#12768 ACs: trim the fields, measure the schema byte-size, update specs). Residual: the 3 integration specs (auth / heartbeat / healthcheck) are adapted to the lean shape but execute only in CI's integration-unified (Docker MC env) — verified logically here, CI-verified at runtime.

What trimmed (output ↔ openapi ↔ spec kept in sync)

  • features.wake.gateReason (the multi-sentence incident string) — kept gateState / gateTrippedAt / gateTrippedBy / daemonRunning / lastPulseAt / secondsSinceLastPulse.
  • providers.embedding.writeCanary field — but the detection is preserved: the embedding write-probe still runs and still degrades status + pushes a details[] entry on a starved write path; only the verbose per-call sub-object is removed.
  • providers.summary.{endpoint, credential} — kept active / host / model / local.
  • providers.auth block (+ the now-dead buildAuthProviderBlock).
  • empty / transient blocks: orchestrator.tasks (+ dead buildTaskOutcomesBlock; recordTaskOutcome + #taskOutcomes KEPT — dozens of orchestrator callers depend on them), startup (+ the orphaned recordStartupSummarization), and the null dream block.

Headline metric: openapi HealthCheckResponse schema 11,690 → 7,847 bytes (−32.8%) — the schema loaded into every agent at MCP tool-enumeration (axis 1 of the ticket: the per-agent context-tax).

Two judgment calls for the reviewer (both reversible; neither affects the headline metric — they're detection/observability logic, not schema bytes)

  1. auth block — removing providers.auth drops static boot auth-posture observability (OIDC vs proxy-header vs unconfigured). Trimmed per the ticket's AC; the operative auth signal lives elsewhere (the runtime 401-on-missing-proxy-header + the memory-write source-tag). This is the one block where the observability value is closest to the bloat cost — flag if you'd prefer it retained (a one-block restore; openapi never documented it, so no schema change either way).
  2. writeCanary — trimmed the verbose field but kept the detection. If you'd rather keep the full field, it's the #applyEmbeddingWriteCanary + openapi-embedding + 3-spec hunks.

Deltas from ticket

  • Kept providers.*.{host, model, dimensions} (the load-bearing provider-routing diagnostic): the ticket's KEEP-summary said {active, local}, but its enumerated TRIM list named only writeCanary / credential / endpoint — so I trimmed exactly the enumerated fields, not the routing info.
  • Doc-sweep (per the ticket's doc AC + the #13210 review): swept all live healthcheck-contract docs to the lean shape — MemoryCore.md (incl. the migration block, redirected to its on-demand home doc), SharedDeployment.md, PersistentProcessManagement.md (orchestrator.tasks → a recordTaskOutcome note), AGENTS_STARTUP.md (startup.summarizationStatus → boot-log + features.summarization), contract-ledger.md. No live agentos doc teaches a removed field as current; MultiTenantMigrationGuide.md already documents the on-demand census.
  • Blog sample (learn/blog/context-engineering-done-right.md:1640, the deleted recordStartupSummarization call): not edited under this PR — the file carries 136 trailing-whitespace lines (incl. intentional markdown hard-line-breaks), so the pre-commit whitespace hook blocks any edit without churning/breaking the historical article. It's a dated, served-but-historical blog (lower current-API-guidance risk than the live agentos contract docs above); flagged for a dedicated blog-hygiene pass rather than churned here. Open to a --no-verify-scoped quarantine commit if reviewers prefer it under this PR.
  • SessionService.mjs (−2 lines): the orphaned recordStartupSummarization('skipped') call + its now-unused import removed — no behavioral loss (the logger.warn + features.summarization:false + a details[] entry already carry the no-key signal).

Test Evidence

  • HealthService.spec.mjs: 50 passednpm run test-unit -- test/playwright/unit/ai/services/memory-core/HealthService.spec.mjs.
  • Full memory-core unit suite: 491 passed — confirms no indirect breakage from the SessionService import removal or the deleted projections.
  • 3 integration specs (AuthRejection / HeartbeatPropagation / healthcheck) adapted to the lean shape; they run in CI's integration-unified (Docker MC) — logically reviewed, CI-verified.

Post-Merge Validation

  • Confirm the live MC healthcheck payload matches the lean shape + the openapi schema (output ↔ schema parity).
  • Confirm the embedding write-canary still degrades status on a starved write path (detection preserved despite the field trim).

CI Deferral

I started the #13210 review intake, but I am deferring the formal review until the current head is green.

Live check state at head 4f4ee9f21c24582c206163c38dcfb2232694b8ae:

  • integration-unified is failing.
  • All other visible checks are passing.

The failed job is in the touched healthcheck surface, not unrelated CI noise:

  • test/playwright/integration/healthcheck.spec.mjs:33 expects mcHealth.providers.summary.local to be true, but the Docker payload returns false.
  • test/playwright/integration/HeartbeatPropagation.integration.spec.mjs fails through assertSustainedHealth on the same sustained health assertion family.

Per /pr-review CI gate, I am not posting a full review while CI is red. Please update the integration expectation or healthcheck projection, then re-ping when integration-unified is green.

This is a review deferral, not a verdict on the PR architecture.

PR Review Summary

Status: Request Changes

Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Request Changes
  • Rationale: The implementation core is aligned and the exact head is green, but the PR removes consumed healthcheck fields while leaving current operator/agent documentation that still names those removed fields. Because the PR closes #12768, the doc contract drift cannot be deferred as a vague follow-up.

Thanks for the fast CI repair after the initial integration failure. The code-side trim is in the right direction: the healthcheck stays a liveness/readiness probe, the writeCanary detection path still degrades status and details[], and the OpenAPI schema contraction is real. The blocker is the close-target/doc-sweep layer.


Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: #12768 body and comments, including the needs-re-triage premise-check; current origin/dev healthcheck source/schema; PR changed-file list; local exact-head checkout 968088d2f9b49567d106bcc5ec72a8f7c4809a60; related healthcheck docs under learn/agentos/** and AGENTS_STARTUP.md.
  • Expected Solution Shape: A correct residual trim should delete the verbose residual healthcheck fields, preserve load-bearing degradation signals, keep OpenAPI/output/tests in parity, and sweep every current operator/agent doc that teaches the removed healthcheck fields. It must not hardcode a stale #12768 framing after the primary topology/mailbox/migration work already landed elsewhere. Test isolation should cover the pure projection changes plus the integration assertions that previously depended on deleted fields.
  • Patch Verdict: The code and tests match the lean-probe shape, but the docs contradict the delivered contract. HealthService.mjs no longer emits startup, orchestrator.tasks, or migration, yet current docs still instruct agents/operators around those healthcheck fields.

Context & Graph Linking

  • Target Epic / Issue ID: Resolves #12768
  • Related Graph Nodes: needs-re-triage source-ticket state; healthcheck output/schema contract; Memory Core boot/startup guidance; wake-substrate healthcheck docs.

Depth Floor

Challenge: The PR treats the remaining doc drift as out-of-scope, but closing #12768 makes that unsafe. The issue's own late doc-sweep comment exists because prior slices orphaned operator docs; this PR currently repeats that failure for still-current docs.

Rhetorical-Drift Audit (per guide §7.4):

  • PR description: partially drifted. It says the residual completes #12768 while also admitting pre-existing migration doc drift is left untouched.
  • Anchor & Echo summaries: implementation comments on writeCanary are precise and match the code.
  • [RETROSPECTIVE] tag: N/A.
  • Linked anchors: the #13071 / #13075 residual framing is plausible, but it does not discharge #12768's doc contract while current docs still teach deleted fields.

Findings: Blocker: framing and docs must converge before this can close #12768.


Graph Ingestion Notes

  • [KB_GAP]: Current docs still teach removed Memory Core healthcheck fields, so future KB/agent queries will inherit a false payload contract if this lands as-is.
  • [TOOLING_GAP]: None observed. gh pr checks is green and the focused unit run passed locally.
  • [RETROSPECTIVE]: The lean writeCanary pattern is a good compromise: keep degradation detection in status + details[], drop verbose per-call shape from the hot healthcheck payload.

Close-Target Audit

  • Close-targets identified: #12768.
  • #12768 confirmed not epic-labeled.
  • PR body uses newline-isolated Resolves #12768; branch commits use (#12768) subjects and do not introduce stray Closes / Fixes targets.

Findings: Syntax passes. Semantic close-target honesty is blocked by the unresolved doc sweep below.


Contract Completeness Audit

  • Originating ticket contains a Contract Ledger matrix.
  • Implemented PR diff matches the live contract everywhere consumed.

Findings: Contract drift remains in current docs:

  • AGENTS_STARTUP.md:124 still says healthcheck.startup.summarizationStatus === "not_attempted" is the empirical boot signal, but this PR deletes the startup block and recordStartupSummarization().
  • learn/agentos/MemoryCore.md:82 still says healthcheck checks effective topology; learn/agentos/MemoryCore.md:88 still frames the payload as covering multi-tenant migration state; learn/agentos/MemoryCore.md:110 still shows a top-level migration block; learn/agentos/MemoryCore.md:138 still documents migration field semantics. Current HealthService emits none of that.
  • learn/agentos/wake-substrate/PersistentProcessManagement.md:115 still says the healthcheck exposes orchestrator.tasks, but this PR removes the orchestrator block from the payload.
  • learn/blog/context-engineering-done-right.md:1640 still contains a code sample calling the deleted HealthService.recordStartupSummarization(); either update it if it is current guidance or explicitly mark it historical so it is not mistaken for live API.

Evidence Audit

Findings: Pass with a caveat. PR body declares L2 evidence; local focused unit verification passed (npm run test-unit -- test/playwright/unit/ai/services/memory-core/HealthService.spec.mjs, 50/50), and GitHub CI is green including integration-unified. The doc contract caveat above is not a test-evidence failure; it is a consumed-surface completeness failure.


MCP-Tool-Description Budget Audit

For the touched OpenAPI surface:

  • No new verbose descriptions were introduced.
  • Deleted writeCanary, credential, and startup schema blocks reduce runtime-loaded schema size.
  • Remaining touched descriptions are usage-focused; no new internal cross-refs or architectural narrative were added.

Findings: Pass.


Cross-Skill Integration Audit

Findings: The PR changes a consumed healthcheck wire format. Integration tests were updated, but current agent/operator docs were not fully updated. The AGENTS_STARTUP.md stale boot signal is especially high-risk because it is startup guidance, not archival history.


Test-Execution & Location Audit

  • Branch checked out locally with gh pr checkout 13210.
  • Exact-head verified: local HEAD equals PR head 968088d2f9b49567d106bcc5ec72a8f7c4809a60.
  • Canonical Location: changed tests remain under existing test/playwright/unit/ai/services/memory-core/ and test/playwright/integration/ paths.
  • Related verification run: npm run test-unit -- test/playwright/unit/ai/services/memory-core/HealthService.spec.mjs -> 50 passed.
  • CI check: integration-unified, unit, lint, CodeQL, and PR-body lint are green on the current head.

Findings: Pass.


Required Actions

To proceed with merging, please address the following:

  • Sweep the live healthcheck contract docs for fields this PR removes, at minimum: AGENTS_STARTUP.md:124, learn/agentos/MemoryCore.md:82, learn/agentos/MemoryCore.md:88, learn/agentos/MemoryCore.md:110, learn/agentos/MemoryCore.md:138, and learn/agentos/wake-substrate/PersistentProcessManagement.md:115.
  • Resolve or explicitly quarantine the deleted-method sample in learn/blog/context-engineering-done-right.md:1640 so it cannot be read as current API guidance.
  • After the doc sweep, tighten the PR body so it no longer says the migration doc drift is out-of-scope while also closing #12768. Either complete the sweep under this PR, or change the close-target/framing so #12768 is not being closed with known live contract drift.

Evaluation Metrics

  • [ARCH_ALIGNMENT]: 90 - 10 points deducted because the code follows the lean liveness/readiness principle, but the consumed documentation layer is not aligned with the new wire contract.
  • [CONTENT_COMPLETENESS]: 70 - 30 points deducted because the PR body and several docs were updated, but current docs still teach deleted healthcheck fields and the PR body explicitly leaves one known drift out-of-scope while closing #12768.
  • [EXECUTION_QUALITY]: 90 - 10 points deducted for the contract-doc miss; the runtime path itself is verified by focused unit tests and green CI, and writeCanary failure detection remains covered.
  • [PRODUCTIVITY]: 70 - 30 points deducted because the residual trim is mostly delivered, but #12768 should not close while the live docs still contradict the delivered healthcheck shape.
  • [IMPACT]: 60 - Substantive runtime-loaded schema and hot healthcheck payload contraction, but scoped to one Memory Core healthcheck surface.
  • [COMPLEXITY]: 55 - Moderate: code, schema, tests, CI integration expectations, source-ticket staleness, and docs all move together.
  • [EFFORT_PROFILE]: Maintenance - This is valuable cost/control cleanup of an existing surface, not a new architectural pillar.

PR Review Follow-Up Summary

Status: Approved

Cycle: Cycle 2 re-review

Opening: Prior Request Changes on the live healthcheck-doc contract is addressed at head 25349a64; the remaining blog sample is accepted as non-blocking historical hygiene.


Patch-Blind Premise Snapshot

  • Inputs Read Before Patch: Prior review PRR_kwDODSospM8AAAABC8oZPA; #12768 body/comments including the doc-sweep AC; current PR body; changed-file list; exact local checkout 25349a64b995c66cd28920cb0e051580ac99141e; live AGENTS_STARTUP.md, learn/agentos/MemoryCore.md, learn/agentos/SharedDeployment.md, learn/agentos/wake-substrate/PersistentProcessManagement.md, and the residual blog sample.
  • Expected Solution Shape: The delta should sweep current operator/agent docs that teach removed healthcheck fields, keep output/schema/tests in parity, and not re-expand the lean healthcheck contract. It must not hardcode deleted fields into live guidance. Test isolation should rerun the focused HealthService unit spec and rely on CI for Docker integration specs.
  • Patch Verdict: Matches the expected shape. The live contract docs named in the prior blocker now describe the lean payload; the blog sample remains stale but is a dated narrative article, not the active healthcheck contract surface.

Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

  • Decision: Approve
  • Rationale: The merge-blocking live-doc drift is fixed, code/schema/tests are green, and the remaining blog sample has a concrete rationale for deferral. Blocking the lean healthcheck trim on a whitespace-heavy historical article would be worse ROI than accepting it as future blog hygiene.

Prior Review Anchor

  • PR: #13210
  • Target Issue: #12768
  • Prior Review Comment ID: PRR_kwDODSospM8AAAABC8oZPA
  • Author Response Comment ID: A2A author response plus commit 25349a64b / PR-body update
  • Latest Head SHA: 25349a64b995c66cd28920cb0e051580ac99141e

Delta Scope

  • Files changed: Live docs added to the prior code/schema/test diff: AGENTS_STARTUP.md, learn/agentos/MemoryCore.md, learn/agentos/SharedDeployment.md, learn/agentos/process/contract-ledger.md, learn/agentos/wake-substrate/PersistentProcessManagement.md.
  • PR body / close-target changes: Pass. Resolves #12768 remains newline-isolated; body now documents the doc sweep and blog deferral rationale.
  • Branch freshness / merge state: Pass. PR is open, not draft, unmerged, and green at 25349a64.

Previous Required Actions Audit

  • Addressed: Sweep live healthcheck contract docs for removed fields — verified diffs in AGENTS_STARTUP.md, MemoryCore.md, SharedDeployment.md, contract-ledger.md, and PersistentProcessManagement.md; live docs no longer teach startup.summarizationStatus, migration, providers.auth, credential, endpoint, gateReason, or orchestrator.tasks as current healthcheck contract fields.
  • Rejected with rationale: Edit/quarantine learn/blog/context-engineering-done-right.md sample — accepted as non-blocking. The sample is stale, but it sits in a dated historical blog with broad trailing-whitespace churn risk; the PR body names the deferral and the live contract docs were corrected.
  • Addressed: Tighten PR body close-target framing — the body no longer frames live doc drift as out-of-scope while closing #12768.

Delta Depth Floor

  • Delta challenge: The blog still contains HealthService.recordStartupSummarization() and future agents should not cite it as current API guidance. I am not treating that as merge-blocking because the authoritative live Agent OS docs and OpenAPI schema now carry the correct lean contract, and the PR body documents why the historical article was deferred.

Conditional Audit Delta

Close-Target Audit

  • Findings: Pass. The PR body carries Resolves #12768, #12768 is not an epic, and branch commit subjects use (#12768) without stray Closes / Fixes targets.

Contract Completeness Audit

  • Findings: Pass for live consumed surfaces. The healthcheck output/schema/tests and the current operator/agent docs are aligned. The residual blog sample is recorded as historical hygiene, not a live contract blocker.

N/A Audits — MCP Tool Description / Turn-Memory / Provenance

N/A across listed dimensions: no new MCP tool surface, no turn-loaded instruction substrate, and no novel external-origin abstraction.


Test-Execution & Location Audit

  • Changed surface class: code / schema / tests / docs.
  • Location check: Pass. Unit and integration tests remain in existing canonical test/playwright/unit/ai/services/memory-core/ and test/playwright/integration/ paths.
  • Related verification run: npm run test-unit -- test/playwright/unit/ai/services/memory-core/HealthService.spec.mjs -> 50 passed at local head 25349a64. GitHub unit and integration-unified are both green on the same head.
  • Findings: Pass.

Metrics Delta

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

  • [ARCH_ALIGNMENT]: 90 -> 95. Live docs now match the lean healthcheck contract; 5 points remain deducted for the historical blog sample still carrying a deleted-method example.
  • [CONTENT_COMPLETENESS]: 70 -> 90. The doc-contract blocker is swept; 10 points remain deducted because the blog article is deferred rather than updated.
  • [EXECUTION_QUALITY]: 90 -> 95. Focused unit test and CI are green; 5 points remain deducted for the accepted historical-doc hygiene residue.
  • [PRODUCTIVITY]: 70 -> 95. The residual #12768 trim is now merge-ready; the stale blog sample is not live-contract enough to hold the ticket open.
  • [IMPACT]: unchanged from prior review — 60. Substantive schema/payload contraction on one Memory Core healthcheck surface.
  • [COMPLEXITY]: unchanged from prior review — 55. Moderate: code, schema, docs, tests, and source-ticket staleness move together.
  • [EFFORT_PROFILE]: unchanged from prior review — Maintenance. Valuable cost/control cleanup of an existing surface.

Required Actions

No required actions — eligible for human merge.
