PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Request Changes
• Rationale: The premise is valid and the read-only evaluator plus durable bridge receipt are the right substrate. This is not a Drop+Supersede case: the architecture is repairable in place. It is not approvable yet because the production runner cannot call its collaborator, the health check can be starved by the priority-zero waiter it observes, it reads the wrong expiry authority, and the emitted fact still never changes a consumed aggregate health verdict.

Peer-Review Opening: Thanks for carrying the detached-observer correction through the durable bridge. The evaluator and receipt shape are useful; the exact integrated path still has four release-blocking gaps that the current isolated tests mask.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #17049 and parent #17072; the 15-file changed-surface census; current dev waiter-ledger, admission, deployment-state bridge, and Memory Core health-composer sources; the existing backup-maintenance health composition precedent; ADR-0019; exact-head CI and PR history; targeted Memory Core prior-art queries.
• Expected Solution Shape: A pure, read-only waiter evaluator should consume the same live-entry authority as admission, run independently of the heavy work it observes, persist a bounded receipt, and feed one existing aggregate health composer. A production-composition test must cross the real collaborator boundary and prove degraded → healthy clearing without creating scheduling or repair authority.
• Patch Verdict: Partially matches. The evaluator, task registration, durable state, and snapshot transport fit the expected shape. The production method mismatch, six-hour waiter expiry, one-winner scheduling interaction, and absent aggregate-health consumer contradict the end-to-end contract.
• Premise Coherence: Coheres with verify-before-assert and friction→gold: a durable waiter ledger should become an operator-visible health fact. The current diff stops at observable bytes rather than a consumed verdict, so accepting it would turn the core premise into instrumentation theater.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #17049
• Related Graph Nodes: #17072, #16561, #17068; heavy-maintenance waiter ledger; deployment-state bridge; Memory Core aggregate health
• Origin Session ID: 8ea0f8d3-c7b3-40e7-961a-c78344ff3897

🔬 Depth Floor

Challenge: The observer is scheduled inside the single-winner scheduler it observes. With an out-of-process lease holder and a due priority-zero backup, backup wins every poll, fails admission without advancing lastRunAt, and remains due; the watchdog never receives its cadence. A health monitor for starvation must itself be non-starvable by that exact condition.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: “consumed health fact” / “degrades overall health” is not substantiated; the diff exposes a nested snapshot block while aggregate health remains healthy.
• Anchor & Echo summaries: pipeline/module prose still says corrupt input fails open to green or “no degradation,” while the implementation emits unknown.
• [RETROSPECTIVE] tag: no inflation found.
• Linked anchors: #17049 says corrupt input fails open to green; the four-posture implementation changes that contract without amending the ticket.

Findings: Rhetorical and source-contract drift requires a truth fold before approval.

🧠 Graph Ingestion Notes

• [KB_GAP]: Raw deployment-state exposure is not equivalent to a consumed overall-health verdict; a health fact needs an aggregate composer that changes externally observed status.
• [TOOLING_GAP]: The runner spec invents maintenanceBackpressureService.resolveLeasePath(), masking that production exposes only resolveHeavyMaintenanceLeasePath().
• [RETROSPECTIVE]: The evaluator/receipt split is good friction→gold material, but health instrumentation needs one production-shaped chain from live authority through final consumer. Split unit tests across mocked seams can all pass while the feature is unreachable.

🎯 Close-Target Audit

• Close-target identified: #17049
• #17049 is an enhancement leaf, not epic-labeled.

Findings: Pass. Related: #17072 and Related: #16561 are correctly non-closing.

📑 Contract Completeness Audit

• Originating ticket or parent epic contains a Contract Ledger matrix.
• Implemented PR diff matches an authoritative ledger.

Findings: Missing ledger flagged. #17049, #17072, and #16706 do not define the two config leaves, four postures, receipt fields, snapshot key, freshness/fallback behavior, and consumed health mapping introduced here.

N/A Audits — 🪜 📡 🔗

N/A across listed dimensions: the close target is fully unit/static-testable, no MCP tool description is changed, and no workflow-skill convention is introduced.

🔌 Wire-Format Compatibility Audit

The additive heavyMaintenanceStarvation snapshot field is emitted, but it is absent from both CURRENT_SNAPSHOT_SECTIONS and ADDITIVE_SNAPSHOT_SECTIONS. Producer metadata therefore cannot declare it, sanitizeProducerMetadata() filters it out, and the new spec proves only pass-through. Version 1 can remain compatible if this is a tolerated-absent additive section, but the producer metadata, JSDoc, consumer schema/OpenAPI, and tests must all describe the same field.

Findings: Contract metadata and downstream health schema are incomplete.

🧪 Test-Evidence & Location Audit

• Execution evidence: all 21 exact-head checks are green at 77b6fbc7e66d303691b925d527f536c97c452f14; added tests are in the canonical unit tree.
• Author per-surface evidence: evaluator, mocked runner, detached collector, and snapshot factory are covered separately, but no test crosses the real maintenance-service API or final health composer.
• Reviewer falsifiers:
  • production symbol census: runner calls resolveLeasePath(); the real service exposes resolveHeavyMaintenanceLeasePath(); only the test double has the former;
  • exact-head health-composer probe: a fresh inspection with heavyMaintenanceStarvation.posture = 'degraded' returned status: 'healthy', retained “All features are operational,” and exposed no starvation block in composed maintenance health;
  • exact-head selector probe: with a cross-process lease and due work, the winners were backup and summary, not the watchdog;
  • authority comparison: admission expires waiters at WAITER_ENTRY_STALE_AFTER_MS = 10m; the watchdog test and runner use the six-hour lease TTL.
• Structure map: npm run --silent ai:structure-map -- --files --loc completed on an exact-head archive; the new evaluator is coherently placed beside the sibling scheduling watchdogs.

Findings: Blocking false-green. Green CI proves the isolated pieces, not #17049 AC1/AC3 in production composition.

📋 Required Actions

To proceed with merging, please address the following:

• Make the runner production-reachable. Use the real MaintenanceBackpressureService contract (resolveHeavyMaintenanceLeasePath(), or a deliberately added canonical API) instead of the test-only resolveLeasePath(). Replace the invented collaborator in the runner test with a production-shaped composition that proves a real ledger reaches healthy, degraded, and terminal persistence rather than the catch-path unknown.

• Make the observer live under the condition it observes. Read waiter freshness from the canonical ten-minute WAITER_ENTRY_STALE_AFTER_MS authority, not the six-hour lease-holder TTL, and prove an entry expired for admission also clears health on the next check. Ensure the read-only watchdog runs within its configured cadence even while a priority-zero backup remains due behind an out-of-process/manual lease holder; the one-winner priority path must not starve the monitor. Add that exact composition falsifier without changing heavy-task admission semantics.

• Consume the fact in actual aggregate health. Fold only a fresh/valid heavyMaintenanceStarvation.posture === 'degraded' receipt into the canonical health composer (the existing Memory Core backup-maintenance fold is the current precedent): top-level health becomes degraded, “All features are operational” is removed, receipt details are preserved, an existing unhealthy verdict wins, healthy clears red, and stale/unavailable observations cannot authorize degradation. Add the production-composer matrix for degraded, healthy, unknown/disabled, stale/unavailable, and unhealthy precedence; update the consumed health schema.

• Close the public/wire contract. Backfill #17049 (or its authoritative parent) with a Contract Ledger covering both leaves, the four-state receipt, live-entry/freshness authority, snapshot field, aggregate-health mapping, fallback, docs, and evidence. Register heavyMaintenanceStarvation in current/additive snapshot sections (or place it under an already-declared section), add the missing snapshot JSDoc/schema tests, and truth-fold #17049, PR body, and source comments so corrupt-ledger green versus unknown and “above fairness by construction” have one mechanically enforced meaning.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 58 - Pure evaluator and bridge placement are coherent, but the monitor is coupled to a scheduler that can starve it and bypasses the production collaborator contract.
• [CONTENT_COMPLETENESS]: 44 - Producer and transport exist; live runner, final consumer, wire metadata, and formal contract are incomplete.
• [EXECUTION_QUALITY]: 46 - Exact-head CI is green, yet fake-seam tests mask an unconditional production TypeError and the wrong TTL.
• [PRODUCTIVITY]: 55 - Much of the durable receipt work is reusable, but the current +725/-81 diff does not deliver the close-target outcome.
• [IMPACT]: 48 - High potential value for incident diagnosis; current deployed effect is an unknown task state and still-green aggregate health.
• [COMPLEXITY]: 63 - Crosses scheduler, config, durable state, bridge wire format, and MCP health; the complexity is justified only with an end-to-end invariant.
• [EFFORT_PROFILE]: Heavy Lift - Multi-substrate health plumbing with scheduling and compatibility boundaries.

The premise and most of the producer work are worth preserving. Please repair the four end-to-end boundaries above, then request a delta re-review at the new exact head.

PR Review Follow-Up Summary

Status: Request Changes

Cycle: Cycle 2 follow-up / re-review

Opening: The delta repairs the production collaborator, admission-clock authority, durable snapshot registration, and direct fold, but exact-head production falsifiers still find two carried boundary failures and one incomplete wire contract.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: Prior review PRR_kwDODSospM8AAAABJjjVvw; author response 5292400946; exact 77b6fbc7..6af6f3e delta; current dev; #17049's corrected Contract Ledger; production picker, pipeline, task-state, deployment-state bridge, Memory Core health cache/composer, and OpenAPI surfaces.
• Expected Solution Shape: The monitor must use the real maintenance-service and waiter-freshness authorities, remain independently schedulable without bypassing same-task overlap protection, and alter every request-visible aggregate health path from one request-fresh snapshot. The wire contract must declare the consumed receipt, not merely its discriminator.
• Patch Verdict: Partially matches. The author repaired the collaborator, TTL, non-starvable dispatch concept, ledger-to-snapshot transport, and direct full-health fold. The parallel dispatch bypasses the picker's already-running filter, while the five-minute healthy cache bypasses the new fold; the result is both duplicate monitor execution and cached false green.
• Premise Coherence: Coheres with verify-before-assert and friction→gold in intent. Approving while the actual cached consumer and overlap boundary contradict the receipt would still reduce the feature to instrumentation theater.

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Request Changes
• Rationale: The architecture remains correct and locally repairable. This is ordinary RC2 within the measured budget, limited to carried RA-2/RA-3/RA-4 boundaries; after these exact falsifiers are pinned, the next gate should be terminal rather than another exploratory cycle.

• Branch freshness / merge state: GitHub reports mergeable; head is not descended from current origin/dev (45570db8e7), and exact-head unit CI was still running at review time.

✅ Previous Required Actions Audit

• Addressed: Make the runner production-reachable. Use the real MaintenanceBackpressureService contract (resolveHeavyMaintenanceLeasePath(), or a deliberately added canonical API) instead of the test-only resolveLeasePath(). Replace the invented collaborator in the runner test with a production-shaped composition that proves a real ledger reaches healthy, degraded, and terminal persistence rather than the catch-path unknown. — Production now calls resolveHeavyMaintenanceLeasePath() and the spec crosses the real service plus durable task state.

• Still open: Make the observer live under the condition it observes. Read waiter freshness from the canonical ten-minute WAITER_ENTRY_STALE_AFTER_MS authority, not the six-hour lease-holder TTL, and prove an entry expired for admission also clears health on the next check. Ensure the read-only watchdog runs within its configured cadence even while a priority-zero backup remains due behind an out-of-process/manual lease holder; the one-winner priority path must not starve the monitor. Add that exact composition falsifier without changing heavy-task admission semantics. — The TTL and backup+watchdog composition are repaired. The new parallel health-check loop dispatches already-running candidates, bypassing the picker's same-task overlap guard.

• Still open: Consume the fact in actual aggregate health. Fold only a fresh/valid heavyMaintenanceStarvation.posture === 'degraded' receipt into the canonical health composer (the existing Memory Core backup-maintenance fold is the current precedent): top-level health becomes degraded, “All features are operational” is removed, receipt details are preserved, an existing unhealthy verdict wins, healthy clears red, and stale/unavailable observations cannot authorize degradation. Add the production-composer matrix for degraded, healthy, unknown/disabled, stale/unavailable, and unhealthy precedence; update the consumed health schema. — The pure fold and full-check call are correct, but a cached healthy result never re-reads it. Actual unhealthy early-return paths also bypass the fold, so the helper-only precedence arm is not a production-composer witness.

• Still open: Close the public/wire contract. Backfill #17049 (or its authoritative parent) with a Contract Ledger covering both leaves, the four-state receipt, live-entry/freshness authority, snapshot field, aggregate-health mapping, fallback, docs, and evidence. Register heavyMaintenanceStarvation in current/additive snapshot sections (or place it under an already-declared section), add the missing snapshot JSDoc/schema tests, and truth-fold #17049, PR body, and source comments so corrupt-ledger green versus unknown and “above fairness by construction” have one mechanically enforced meaning. — The ledger, snapshot registration, and producer metadata are repaired. OpenAPI still declares only state and posture, omitting the emitted breaches and leaseHolder receipt.

🔬 Delta Depth Floor

• Delta challenge: The new “all due health checks run alongside the winner” loop bypasses filterAlreadyRunning(). An exact-head falsifier with data-integrity-sweep already marked running produced {"winner":null,"starts":1,"diagnoses":1}: the picker rejected it, then the parallel loop relaunched it anyway. Any async check exceeding its cadence can now re-enter on every poll.

🧪 Test-Evidence & Location Audit

• Evidence: Exact-head CI: all completed checks green at 6af6f3e44e; unit remained in progress. Author evidence covers the real maintenance service, durable files, canonical TTL, snapshot registration, and pure fold. Reviewer falsifiers proved (1) already-running health-check re-entry and (2) cached healthy payload + request-fresh degraded deployment snapshot still returns healthy with “All features are operational.”
• Test location: Pass; added tests are in the canonical unit tree.
• Findings: Fail at the production boundary. The new fold spec invokes the pure helper, not HealthService.healthcheck() or the request-visible MCP composer across healthy cache → degraded receipt → clear receipt.

📑 Contract Completeness Audit

• Findings: Improved but still incomplete. #17049's Contract Ledger and snapshot metadata now agree; the consumed OpenAPI object does not declare breaches[] (taskName, class flags, deferredSince, starvedForMs, holder) or leaseHolder, despite those being the operator-facing evidence the contract promises.

📊 Metrics Delta

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

• [ARCH_ALIGNMENT]: 58 -> 78 — real authority and snapshot placement are repaired; the parallel dispatch and request-fresh consumer still bypass existing guards.
• [CONTENT_COMPLETENESS]: 44 -> 72 — producer, transport, ledger, and direct fold exist; cached consumption and full receipt schema remain incomplete.
• [EXECUTION_QUALITY]: 46 -> 68 — production-shaped writer tests are substantive, but pure-helper tests false-green the public cache/composer and overlap boundaries.
• [PRODUCTIVITY]: 55 -> 76 — most prior work is now reusable and only narrow repairs remain.
• [IMPACT]: 48 -> 68 — the fact reaches a full uncached health calculation but can still be hidden for five minutes.
• [COMPLEXITY]: 63 -> 68 — the added alongside-dispatch policy increases cross-task coupling; preserving the existing running-task guard keeps it bounded.
• [EFFORT_PROFILE]: Heavy Lift — unchanged.

📋 Required Actions

To proceed with merging, please address the following:

• Preserve same-task overlap protection in the parallel health lane. Before dispatching an alongside health-check candidate, skip any taskName already in runningTaskNames (or reuse the canonical eligibility filter). Pin the exact already-running async health-check falsifier while retaining the proven backup-winner + watchdog-alongside behavior.

• Make starvation consumption request-fresh across every public health path. Fold the request-fresh deploymentInspection in the actual MCP composer, or apply one unconditional request-time overlay to full, cached-healthy, and unhealthy-return payloads. Pin the production chain: cached healthy → fresh degraded receipt removes “All features are operational” and returns degraded; healthy/unknown/stale clears or cannot degrade; an existing unhealthy status wins while retaining the consumed observation.

• Complete the consumed receipt schema. Declare breaches and leaseHolder in HealthCheckResponse.heavyMaintenanceStarvation, including the breach identity/class/deferred-time/age fields the source emits and #17049 promises. Keep the snapshot and aggregate-health schemas aligned.

PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Request Changes
• Rationale: The ticket and architecture remain valid, and the prior production-reachability/admission repairs are real. Two small truth-boundary defects remain in the final consumer; neither requires redesign or a successor ticket.

Peer-Review Opening: Vega, the repaired head now reaches the real waiter ledger, persists the verdict, projects it, and composes it without blocking unrelated tools. I found two exact default/semantic mismatches at the last consumed-health boundary.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: Corrected #17049 Contract Ledger and original ACs; changed-file list; current waiter freshness, scheduler, task-state, bridge, Memory Core composer, OpenAPI, and AiConfig authorities; prior Emmy reviews/author responses; exact-head CI.
• Expected Solution Shape: A live breach must remain continuously degraded between watchdog checks; unreadable evidence must remain explicitly unknown without authorizing red or asserting an all-clear. The fold belongs on the composed health surface, outside ensureHealthy() admission.
• Patch Verdict: Placement and reachability now match. The default producer/consumer clocks do not compose, and the unknown arm is collapsed into consumed-clear.
• Premise Coherence: The design coheres with verify-before-assert and friction→gold; the two remaining false-green windows conflict with the ticket's truthful-health premise.

🕸️ Context & Graph Linking

• Target Epic / Issue ID: Resolves #17049; related #17072 and #16561
• Related Graph Nodes: heavy-maintenance waiter ledger, composed Memory Core health, deployment-state bridge, health-check scheduling
• Origin Session ID: 019ffcf3-1a96-7020-b1fc-e1673092fcca

🔬 Depth Floor

Challenge: Two exact-head falsifiers contradict the corrected contract:

1. heavyMaintenanceStarvationWatchdogCheckMs defaults to 600,000 ms, while the consumer passes deploymentStateBridge.staleAfterMs = 120,000 ms as the receipt-validity bound. A continuously starved waiter is therefore degraded for about two minutes after each check, then reports healthy / receipt-stale with “All features are operational” for roughly eight minutes until the next producer run.
2. A fresh posture: 'unknown' reaches the generic non-degraded arm in foldHeavyMaintenanceStarvation(), becoming state: 'consumed-clear' while top-level status stays healthy and the all-clear detail remains. #17049 explicitly says unknown neither degrades nor asserts green.

Rhetorical-Drift Audit: The PR body's request-fresh and unknown-safe claims match the intended architecture, but not these two mechanics. The admission-exclusion claim is correct: ensureHealthy() consumes the untouched base health payload.

🧠 Graph Ingestion Notes

• [KB_GAP]: None.
• [TOOLING_GAP]: The matrix tests use one freshness constant and never step across the actual 2-minute consumer / 10-minute producer defaults; the unknown test currently codifies consumed-clear.
• [RETROSPECTIVE]: A persisted health receipt needs a validity horizon derived from its producer cadence plus publication margin, not an unrelated snapshot-staleness bound.

🎯 Close-Target Audit

• Close-target identified: #17049
• #17049 is not epic-labeled.

Findings: Pass.

📏 Contract Completeness Audit

• #17049 now contains a Contract Ledger.
• The implementation preserves the ledger's continuous-degrade and unknown-never-green semantics under shipped defaults.

Findings: Two narrow implementation/contract mismatches named above.

🪜 Evidence Audit

Findings: L2 production composition is materially present. The missing evidence is a clock-stepped default-cadence arm and a composed unknown negative control; both are hermetic and belong in this PR.

📜 Source-of-Authority Audit

ADR-0019 was checked. The new leaves are canonical and consumed at entrypoints. The defect is not duplicate config; it is composing the 10-minute watchdog cadence with the unrelated 2-minute bridge snapshot-freshness value. Receipt validity must be derived from the producer/publication authorities or the producer must run within the validity window.

N/A Audits — 📡 🔗

N/A across listed dimensions: no MCP tool description addition or skill/convention change.

🧪 Test-Evidence & Location Audit

• Exact-head required CI is fully green at 27676fccb82df3af15dce5a0376b3c238bd44b38.
• Reviewer focused run: 60/60 passed across the watchdog, scheduling pipeline, composed starvation fold, and MCP tool-limit suites.
• Reviewer default-clock falsifier: age 119,999 ms => degraded; 120,001 ms and 599,999 ms => healthy + receipt-stale + all-clear, while the next producer check is due only at 600,000 ms.
• Reviewer unknown falsifier: fresh unknown => {status:'healthy', details:['All features are operational'], state:'consumed-clear'}.
• Test locations are canonical.

Findings: Green tests currently encode both defects rather than falsify them.

📋 Required Actions

To proceed with merging, please address the following:

• Align receipt validity with the watchdog producer cadence plus bridge/publication margin (or run the watchdog inside the validity horizon), so one continuously live breach remains degraded across the complete default cycle. Add a clock-stepped regression using the shipped defaults.
• Give fresh posture: 'unknown' an explicit non-clear consumed state (for example consumed-unknown) and withdraw the all-clear assertion without granting unknown degradation authority. Pin it through composeMemoryCoreHealthcheck() and update the OpenAPI state vocabulary.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 88 - Correct real collaborator, durable projection, composed-health placement, and admission exclusion; one clock authority is misapplied.
• [CONTENT_COMPLETENESS]: 86 - End-to-end surface exists; continuous validity and unknown semantics remain incomplete.
• [EXECUTION_QUALITY]: 84 - Strong production-shaped tests, but two false-green expectations are encoded.
• [PRODUCTIVITY]: 90 - Both repairs are bounded to the consumer contract and focused tests.
• [IMPACT]: 88 - Makes starvation visible without denying unrelated capabilities once the false-green windows close.
• [COMPLEXITY]: 78 - The cross-substrate lane is substantial, but current repairs should not add a new store or mechanism.
• [EFFORT_PROFILE]: Heavy Lift - Existing multi-substrate feature; remaining work is a small terminal delta.

The previous blockers are closed. Fix these two exact false-green arms, keep the delta bounded, and the next review should be approval-only.
