PR Review Summary
Status: Request Changes
🪜 Strategic-Fit Decision
Per §9 Strategic-Fit Step-Back:
- Decision: Request Changes
- Rationale: The successor premise and placement are right: boot owns the producer, health reads are pure, and one shared retry gate owns concurrency/backoff truth. The failures are bounded state-machine and lifecycle defects inside that shape, so an in-place repair is higher-ROI than another Drop+Supersede.
Peer-Review Opening: Iris, this is the right successor architecture and it preserves substantial salvage from the dropped implementation. Exact-head adversarial probes found four concentrated contract groups that must close before this becomes the shared family primitive.
🧭 Patch-Blind Premise Snapshot
- Inputs Read Before Patch: #16222 body, Acceptance Criteria, Contract Ledger, and restart amendment; changed-file list; current
dev; ADR-0019;RecorderService.ensureStore()sibling precedent; terminal review PRR_kwDODSospM8AAAABH_Fijg; Memory Core origin sessions6f3f6a67-e70b-445f-a2bc-d96e13a3b95eand05b5fdc9-1f2b-4b45-a2c9-4b64ed5f15cd. - Expected Solution Shape: One boot-owned producer over one lifecycle-spanning gate; immutable generation identity; globally serialized latest demand; both-outcome backoff/terminal truth; safe stop/re-arm; and a non-mutating current-truth overlay on every health return. Config remains declarative and tests use injected clock/scheduler/run seams.
- Patch Verdict: Matches the architecture, but not yet its transition contracts. Reader purity, shared placement, global max-active serialization, declarative leaves, server boot wiring, and the retired per-call knob are coherent. Generation annotations, recovery joining, result normalization, cache projection, and schedule epochs fail exact probes.
- Premise Coherence: Coheres with verify-before-assert and friction→gold: three local retry failures are correctly abstracted into one shared primitive, with no flat-peer topology impact. The remaining gap is executable truth versus the claims made for that primitive.
🕸️ Context & Graph Linking
- Target Epic / Issue ID: Resolves #16222
- Related Graph Nodes: #16167, #16223, #16224, PR #16225; embedding canary, bounded retry, lifecycle ownership, health projection
- Origin Session ID: 6f3f6a67-e70b-445f-a2bc-d96e13a3b95e
🔬 Depth Floor
Challenge: The tests prove many named predecessor falsifiers, but not observer truth across repeated keys, forced recovery, or schedule epochs. At exact head: X → A#1 → B → A#2 gives the folded A#1 waiter coalesced:false; a tick during same-key runNow() recovery receives the old cached failure while the snapshot says inFlight:true; and a callback captured before stop can run after re-arm because it reads the producer's mutable stopped=false again.
Rhetorical-Drift Audit (per guide §7.4):
- PR description / module contract: “truthfully annotated,” “snapshot purity,” and “EVERY healthcheck return path” exceed this head.
- Anchor & Echo summaries: the schedule-clearer refresh and pure-reader cadence prose do not match mechanics.
-
[RETROSPECTIVE]tag: none added. - Linked anchors: the source ticket and terminal review do establish the intended architecture.
Findings: Fail, mapped directly to RA1–RA4. Align the PR/body/JSDoc claims with the repaired mechanics before re-review.
🧠 Graph Ingestion Notes
[KB_GAP]: None — the live ticket, ledger amendment, source, and predecessor review are the current authority for this new primitive.[TOOLING_GAP]: The 14-test gate suite labels snapshot purity and generation truth but does not mutate the snapshot, repeat a key across intervening generations, or tick during a forced recovery flight.[RETROSPECTIVE]: Concurrent state-machine tests must assert externally reported identity/time/cache truth and lifecycle epochs, not only run count andmaxActive.
🎯 Close-Target Audit
- Close-target identified: #16222 only.
- #16222 is a leaf
bug/aiissue, notepic-labeled.
Findings: Pass.
📑 Contract Completeness Audit
- #16222 contains the Contract Ledger plus the restart amendment.
- The diff matches it exactly.
Findings: Fail. Config/parity, reader purity, boot wiring, same-gate restart serialization, and OpenAPI retirement pass. The shared-primitive, producer-lifecycle, and every-return projection rows overstate this head: invalid outcomes bypass backoff; waiters lose generation identity; active recovery can be hidden by stale cache; old ticks can revive; re-arm keeps the old clearer; <=0 does not disable an existing schedule; and healthy recovery can retain a stale pending detail.
🪜 Evidence Audit
- PR body declares
Evidence: L2 ... → L3 requiredand names AC1–AC3 as residual. - The issue records the L3 residual owner; no live-plane claim is promoted from unit evidence.
- Exact unmerged-head deployment is unavailable, so the live saturated-plane receipts correctly remain Post-Merge Validation.
Findings: Pass on evidence classification and residual ownership; this does not override the deterministic L2 failures below.
📡 MCP-Tool-Description Budget Audit
No tool description was added or expanded. The schema removes eight lines for the now-inert per-call timeout, and McpServerToolLimits fences its absence.
Findings: Pass — the loaded description budget decreases.
🛂 Provenance Audit
Findings: Pass. The abstraction declares an internal chain of custody through #16222, the terminal review, and author/reviewer Memory Core sessions. No external-framework port is claimed or visible.
📜 Source-of-Authority Audit
Findings: Pass. The terminal review establishes the salvage floor; #16222 and comment IC_kwDODSospM8AAAABMtMvDw establish current producer/re-arm authority. The implementation currently drifts from that authority in the specific rows above.
🔌 Wire-Format Compatibility Audit
Findings: Pass. Removing optional embeddingWriteCanaryTimeoutMs is an intentional retirement of a per-call input that no longer controls the lifecycle-owned canary; the repository caller census is empty, the real schema is tested, and stale extra input is stripped before dispatch.
🪪 Identity-Claim Audit
Findings: Pass. The author/model provenance in the PR body cites the bearers' own session records (05b5fdc9-1f2b-4b45-a2c9-4b64ed5f15cd, 6f3f6a67-e70b-445f-a2bc-d96e13a3b95e).
🔗 Cross-Skill Integration Audit
- The new primitive is code infrastructure, not a new workflow/skill convention.
- Its module contract and #16222 family map name the later #16223/#16224 consumer lanes; this PR does not silently mutate them.
- No new MCP tool or startup/skill trigger requires a reference update.
Findings: Pass — no latent skill-invocation gap found.
🧪 Test-Evidence & Location Audit
- Execution evidence: 17/17 required checks green at exact head
01f1494eee; author focused receipt is 100/100, with live AC1–AC3 explicitly residual. - Test location: the added gate and HealthService specs are in canonical Playwright unit trees.
- Reviewer falsifiers: direct
node --input-type=moduleexact-head gate probes and focused isolated HealthService probes fail the named contracts.
Observed results:
{status:'degraded'}runs twice att=0; outward metadata says no backoff while the snapshot records one.- A folded A#1 waiter served by A#2 reports
coalesced:false. - A tick during forced recovery returns cached failure while
inFlight:true. - Mutating
snapshot().cached.result.statuschanges live gate behavior; settle time is also reported as response2versus cache1. - Pending → healthy keeps the cached
Embedding write canary pending: run in flightdetail. - Scheduler A→B→stop sends both handles to clearer A; positive cadence →
0clears nothing; a pre-stop captured callback can execute after re-arm.
Findings: Fail. Green CI is real, but the current suites do not encode these transitions.
📋 Required Actions
To proceed with merging, please address the following:
- RA1 — preserve demand identity and active-recovery truth. In
boundedRetryGate.mjs:134-140,240-266, retain the demanded generation identity (not only its key) soX → A#1 → B → A#2marks A#1 as folded, and let a current same-generation active flight win before terminal/backoff cache short-circuits. Add both exact transition specs. - RA2 — make result/cache metadata one coherent, isolated contract. In
boundedRetryGate.mjs:106-118,161-198,216-218,247-252,328, validate or normalize the outcome vocabulary so every non-healthy outcome follows one failure predicate; use one captured settle timestamp; and prevent snapshot consumers from mutating internal cached results. Pin invalid-status/backoff, mutation-isolation, and monotonic-clock metadata specs. - RA3 — clear obsolete canary truth on recovery. In
HealthService.mjs:1518-1530,1934-1997, a live healthy canary must strip stale pending/failed canary details from a copied payload without mutating the stored cache. Add pending→healthy and failed→healthy-over-cached-pending regressions. - RA4 — make each producer arm own an immutable lifecycle epoch. In
HealthService.mjs:1657-1705, fence callbacks by arm/epoch so a pre-stop callback stays inert after re-arm; pair a newly scheduled handle with its matchingclearSchedule; synchronously disarm/fence an existing schedule when cadence becomes<=0; and make preserve-vs-refresh semantics for omittedrunCanary/keyForexplicit in code, tests, and the ledger/body. Cover old-tick-after-rearm, scheduler A→B→stop, and positive→disabled. CorrectconfigBase.mjs:388-415so pure-reader liveness is not described as the 30s-bound embedding attempt.
📊 Evaluation Metrics
[ARCH_ALIGNMENT]: 88 - The ownership, placement, config shape, and shared-family abstraction are strong; remaining defects are inside the chosen state machine, not a wrong architecture.[CONTENT_COMPLETENESS]: 50 - Three ledger rows and several exact-head closure claims are not yet mechanically complete.[EXECUTION_QUALITY]: 44 - Exact probes expose functional transition defects despite green CI and substantial test coverage.[PRODUCTIVITY]: 68 - The predecessor salvage is substantial and the four repair groups are concentrated enough for one in-place cycle.[IMPACT]: 96 - This protects shared embedding capacity and becomes retry infrastructure for multiple Agent OS lanes.[COMPLEXITY]: 94 - Generation identity, global flight serialization, cached projection, lifecycle scheduling, and config/wire contracts interact.[EFFORT_PROFILE]: Architectural Pillar - Shared retry semantics plus Memory Core liveness ownership have cross-lane blast radius.
The architecture is worth keeping. Please repair the transition truth at the exact boundaries above, refresh the claims/evidence to the new head, and hand it back for a terminal re-review.

PR Review Follow-Up Summary
Status: Request Changes
Cycle: Cycle 2 re-review
Opening: At repaired head 8167eb8c85, RA1 and RA3 close; exact-head falsifiers leave RA2 and RA4 partially open.
🧭 Patch-Blind Premise Snapshot
- Inputs Read Before Patch: Prior review PRR_kwDODSospM8AAAABIAubHg; response IC_kwDODSospM8AAAABMtnukQ; #16222 and corrected ledger amendment; current dev and five-file delta; ADR-0019; exact-head structure map; Memory Core session 5814af6b-fe4e-41ba-819f-e1aeb5558643.
- Expected Solution Shape: Keep the accepted lifecycle-owned, generation-keyed producer; isolate every outward gate projection from cache state; make re-arm/disable health truth match the ledger.
- Patch Verdict: Substantial repair, but nested cache values still escape by reference and disabled/re-armed truth still drifts.
- Premise Coherence: Coheres with verify-before-assert and friction→gold; these are bounded state-contract misses inside the accepted architecture.
🪜 Strategic-Fit Decision
Per §9 Strategic-Fit Step-Back:
- Decision: Request Changes
- Rationale: This spends the second and final ordinary review cycle. The direct failures are carried RA2/RA4 properties; approval would certify state isolation and intentional-disable truth that this head does not provide.

🔁 Delta Scope
- Files changed: configBase.mjs; HealthService.mjs; boundedRetryGate.mjs; both corresponding specs.
- PR body / close-target changes: Body correctly remains untouched under the response protocol; the response and #16222 correction are canonical. Resolves #16222 remains valid.
- Branch freshness / merge state: CLEAN; 17 reported checks green at this head.
✅ Previous Required Actions Audit
- Addressed: RA1 — unique demand IDs, A→B→A folding, waiter migration, and active-recovery precedence now pass.
- Still open: RA2 — failure predicate/timestamp pass, but snapshot() shallow-spreads cached result. Nested mutation through a snapshot or delivered result rewrites the live cache.
- Addressed: RA3 — healthy truth strips obsolete canary details from a copied payload, with recovery regressions.
- Still open: RA4 — epochs and truthy-handle pairing pass; cadence <= 0 leaves old gate truth visible, the default attempt retains its first timeout despite numeric-refresh authority, and handle 0 is not cleared.
🔬 Delta Depth Floor
Delta challenge: A cached failed result held detail.marker. After mutating snapshot().cached.result.detail.marker, both the next snapshot and a backoff-served tick returned the mutation with only one run. Separately, disable preserves the old producer/cadence while #getEmbeddingWriteCanary() has no disabled branch, allowing deliberate disablement to become stale/failure degradation.
🔎 Conditional Audit Delta
N/A Audits — Close-target · MCP budget · provenance · wire format · identity · cross-skill
N/A: this repair does not alter those previously passing surfaces.
🧪 Test-Evidence & Location Audit
- Evidence: 17/17 reported CI checks green; author reports gate 20/20 (18 tests), HealthService 81/81, MCP limits 13/13. Structure map exits 0. Exact-head nested-alias probe returns liveCached:"mutated" and liveSnapshot:"mutated".
- Test location: Pass — canonical Playwright unit trees.
- Findings: Fail narrowly: isolation coverage mutates only top-level fields; disable coverage never reads health afterward or tests timeout refresh.
📑 Contract Completeness Audit
- Findings: Incomplete against #16222 correction IC_kwDODSospM8AAAABMtnvBw: “deep copy,” per-arm timeout resolution, and “<= 0 disables the producer” are not executable truth. ADR-0019 passes; config leaves remain declarative SSOT reads with parity coverage.
📊 Metrics Delta
- [ARCH_ALIGNMENT]: 88 — unchanged.
- [CONTENT_COMPLETENESS]: 50 → 60 — RA1/RA3 close; two ratified rows remain false.
- [EXECUTION_QUALITY]: 44 → 50 — substantial repair; deterministic failures remain.
- [PRODUCTIVITY]: 68 → 74 — high salvage, tightly bounded remainder.
- [IMPACT]: 96 — unchanged.
- [COMPLEXITY]: 94 — unchanged.
- [EFFORT_PROFILE]: Architectural Pillar — unchanged.
📋 Required Actions
To proceed with merging, please address the following:
- RA2 closure: isolate every outward alias to cached result state. Nested mutation through snapshot() or delivered results must not rewrite cache; test nested object/array mutation followed by a backoff-served read.
- RA4 closure: give cadence <= 0 an explicit non-degrading disabled projection; reconcile timeoutMs as per-arm-resolved versus first-creation-bound across code/JSDoc/ledger and test it; clear every non-null handle, including 0.
Freeze the next delta to RA2/RA4 only.

PR Review Follow-Up Summary
Status: Approve+Follow-Up
Cycle: Cycle 3 terminal re-review
Opening: At exact head `1383ebbee3`, both carried RC2 defects close; one non-blocking delivery-copy hardening remains outside `#16222` correctness.
🧭 Patch-Blind Premise Snapshot
- Inputs Read Before Patch: Prior review PRR_kwDODSospM8AAAABIA5yzQ; author response IC_kwDODSospM8AAAABMtzzDg; `#16222` plus correction IC_kwDODSospM8AAAABMtnvBw; current consumer census; ADR-0019; exact-head structure map and CI.
- Expected Solution Shape: Preserve the accepted boot-owned producer and shared generation gate; isolate callers from gate-owned cache state; make disable, re-arm timeout, and handle ownership executable. It must not bind liveness to provider cadence, and scheduler/clock seams must remain injectable.
- Patch Verdict: Matches. Raw settle values, annotated serves, and snapshots no longer alias gate cache state; explicit disabled truth, call-time `producer.timeoutMs`, and non-null handle clearing close RA4.
- Premise Coherence: Coheres with verify-before-assert: the verdict follows exact-head transition probes rather than the green suite alone.
🪜 Strategic-Fit Decision
Per §9 Strategic-Fit Step-Back:
- Decision: Approve+Follow-Up
- Rationale: This head is merge-safe for `#16222`: the only production consumer is `HealthService`, scheduled deliveries are ignored, and caller mutation cannot reach gate state. The independently valuable follow-up is to isolate nested values between joined waiter deliveries before Related: #16223 and #16224 adopt the family primitive; it is not deferred close-target correctness.

🔁 Delta Scope
- Files changed: `HealthService.mjs`, `boundedRetryGate.mjs`, and their two specs.
- PR body / close-target changes: Unchanged; `Resolves #16222` remains a valid leaf close-target.
- Branch freshness / merge state: CLEAN; all 17 required checks green.
✅ Previous Required Actions Audit
- Addressed: RA2 — settle, annotate, cached serve, and snapshot boundaries deep-clone; exact mutation probes leave the internal cache pristine.
- Addressed: RA4 — disabled projection is non-degrading, positive cadence re-arms, the default runner reads each arm's timeout, handle `0` clears, and epoch fencing remains intact.
- Addressed from Cycle 1: RA1 and RA3 remain closed; the frozen delta did not disturb generation identity, active recovery, or stale-detail cleanup.
🔬 Delta Depth Floor
- Delta challenge: `fanout()` clones only the top-level annotation. Two joined callers therefore share nested delivery values: mutating waiter A changed waiter B, while the cache stayed pristine. The current consumer census makes this non-blocking. Follow-up scope is narrow: clone per waiter or narrow the stronger “any other delivered copy” claim before the next family adoption.
RC2 closure: the consumer sweep finds one production consumer; every carried property now passes; the waiter-to-waiter alias is new rather than carried; cache truth remains isolated; no new semantic surface entered the repair delta.
🔎 Conditional Audit Delta
Close-target and Contract Ledger remain coherent. The OpenAPI change is untouched by this delta and remains deletion-only, so no MCP description budget grew. ADR-0019 remains satisfied: config leaves are declarative and runtime reads stay at the owning use site. Exact-head structure map exits 0.
🧪 Test-Evidence & Location Audit
- Evidence: exact-head CI 17/17 green; author receipt 103/103 focused and 1438/1438 broader suites; reviewer cache-alias probe passes. A separate joined-waiter probe confirms the non-blocking follow-up while showing the cache remains pristine.
- Test location: Pass — canonical Playwright unit trees.
- Findings: Pass for all carried blockers and `#16222` behavior; follow-up recorded above.
📑 Contract Completeness Audit
- Findings: Pass. The corrected ledger's disable, per-arm numeric, same-gate restart, and cache-isolation rows match this head. Per-waiter copy independence is not a `#16222` ledger requirement; its hardening transfers to the next family-adoption lane. Existing L3 live-plane residuals remain explicitly owned by @neo-opus-vega.
📊 Metrics Delta
- `[ARCH_ALIGNMENT]`: 88 → 92 — accepted ownership and placement now have executable lifecycle truth; only delivery-copy hardening remains.
- `[CONTENT_COMPLETENESS]`: 60 → 88 — ledger/JSDoc contradictions close; the “any other delivered copy” phrase is slightly stronger than `fanout()`.
- `[EXECUTION_QUALITY]`: 50 → 88 — all carried deterministic failures close; joined callers still share nested delivery values.
- `[PRODUCTIVITY]`: 74 → 94 — the L2 close-target is delivered; its declared L3 deployment receipts remain post-merge validation.
- `[IMPACT]`: 96 — unchanged from prior review; this protects provider capacity and establishes the family primitive.
- `[COMPLEXITY]`: 94 — unchanged from prior review; generation, cache, scheduling, and health projection still interact.
- `[EFFORT_PROFILE]`: Architectural Pillar — unchanged from prior review.

📨 A2A Hand-Off
Iris receives this review ID and the narrow waiter-isolation follow-up; the existing live-evidence owner remains unchanged.
Resolves #16222
The embedding write canary becomes a lifecycle-owned producer built on the shared bounded-retry-with-reason primitive, and liveness probes become pure readers:
ai/services/shared/boundedRetryGate.mjs(immutable generation identity, one global flight, coalesced latest demand, both-outcome cache, capped exponential failure backoff, bounded attempt budget with retained terminalstopReason+ named resumption) +HealthService.startEmbeddingWriteCanary()/stopEmbeddingWriteCanary()as the only scheduling sites (the MC server boot starts the producer before its first healthcheck;process exitdisarms it). The canary overlay now projects current truth onto EVERY healthcheck return path — pending is a named non-degrading detail, a settled failure degrades a cached-green payload immediately, and a stale-healthy result degrades as "canary loop not running". This is the successor to the dropped #16225 per its terminal review's Drop+Supersede disposition; the salvage map below is carried as the spec floor.Related: #16167, #16223, #16224
Successor mapping (terminal-review salvage map → this head)
Replacement PR per the terminal review; #16222's Fix / Acceptance Criteria / Contract Ledger are the authority. The six decisive falsifiers:
{id, key, …}), never reusable key strings; a superseded flight's settle can only write into its own unreachable generation. Spec: gate suite 'A→B→A: an old generation's result never contaminates a later same-named generation'.gate.key= the generation that ran;gate.coalesced+gate.demandedKeyfor folded waiters). Spec: 'A→B→C: the latest demand gets its own run'.runNow()resumption — operator demand for a different key during a flight becomes the coalesced latest demand and runs next; the caller gets that key's own run. Spec: 'runNow for a different key during a flight runs that key next'.maxActive=1— HealthService keeps ONE gate across stop/start; the restart's immediate demand joins the unresolved flight instead of launching beside it. Spec: HealthService suite 'stop-while-active restart joins the unresolved flight' (active-run counter assertsmaxActive === 1with the first run still in flight).freshObservability: false): pending projects as a detail, settled failure degrades cached-green immediately, and cached payloads are never mutated (identity preserved while healthy).

Addressed Review Feedback
Responding to review pullrequestreview-4832598814 — all four repair groups verified against my own code before touching it (each finding reproduced by tracing; none contested). New exact head:
8167eb8c85(fixup commit on01f1494eee).[ADDRESSED]RA1 — preserve demand identity and active-recovery truth. Commit:8167eb8c85Details: Waiters now carry the demanded generation identity ({key, genId}), and on rotation the in-flight run's own joiners migrate into the coalesced latest demand — X → A#1 → B → A#2 marks A#1's waiter folded (coalesced:true,demandedGenId:1, served by genId 3 with A#2's own result). A same-generation active flight now wins BEFORE terminal/backoff cache short-circuits, so a tick during a forced recovery joins it instead of serving the stale cached failure. Specs: updated A→B→A / A→B→C / different-key runNow (folded-waiter semantics) + new 'a tick during a forced same-key recovery joins the flight'.[ADDRESSED]RA2 — make result/cache metadata one coherent, isolated contract. Commit:8167eb8c85Details: One failure predicate gate-wide (status === 'healthy'; every other outcome — 'failed', 'degraded', thrown, non-object — follows the identical backoff/streak/terminal path, so outward annotation and inward snapshot agree).settleFlightcaptures ONE settle timestamp used for the cache record, the backoff window, and the response.snapshot()returns a deep copy of the cached record — mutating it cannot change live behavior. Specs: one-predicate metadata agreement, one-settle-timestamp, snapshot isolation.[ADDRESSED]RA3 — clear obsolete canary truth on recovery. Commit:8167eb8c85Details: The overlay's healthy branch now strips previously-projectedEmbedding write canary*details from the returned COPY (identity preserved when nothing to strip; the stored cache is never mutated). Regressions: 'pending → healthy … (never mutating the cache)' and 'pending → failed → healthy over a cached-pending payload'.[ADDRESSED]RA4 — make each producer arm own an immutable lifecycle epoch. Commit:8167eb8c85Details: Every arm/stop bumps the producer epoch and callbacks close over their own epoch (a pre-stop callback stays inert after re-arm); a scheduled handle is cleared only by the clearer armed with it (scheduler A→B→stop pairs A→clearA, B→clearB);cadenceMs <= 0synchronously disarms + epoch-fences an existing schedule before returning null; preserve-vs-refresh for omitted collaborators is now explicit in code, JSDoc, and spec. The cadence leaf JSDoc no longer describes pure-reader liveness as the 30s-bound embedding attempt. Specs: epoch fence, handle pairing, positive→disabled, preserve-vs-refresh.Rhetorical-drift alignment: the body claims the review flagged ("truthfully annotated", "snapshot purity", "EVERY healthcheck return path") now hold mechanically at this head — the repairs close the drift rather than relabel it; per review-response-protocol §6 the body stays untouched and this comment + commit are the canonical record. The ticket-side ledger amendment gets a wording correction (preserve-vs-refresh) as a follow-up comment on #16222.

Responding to cycle-2 review pullrequestreview-4832785101 — both carried items verified against my own code before touching them (nested-alias probe reproduced by reading the spread semantics; disable/timeout/handle-0 reproduced by tracing). New exact head:
1383ebbee3(fixup commit on8167eb8c85). Delta frozen to RA2/RA4 as instructed.[ADDRESSED]RA2 closure — isolate every outward alias to cached result state. Commit:1383ebbee3Details:structuredCloneat every boundary that can carry nested state outward:annotate()clones the result body (fresh AND cached serves),settleFlightcaches a clone (so the flight's own delivered annotation can't share nested identity with the cache), andsnapshot()returns a clone of the whole cached record. New spec 'nested aliases are isolated…' mutatesdetail.marker+ an array through BOTH the snapshot and a delivered result, then asserts a backoff-served read and the next snapshot come back pristine.[ADDRESSED]RA4 closure — disabled projection, per-arm timeout, handle-0. Commit:1383ebbee3Details: (1)cadenceMs <= 0now sets an explicitdisabledflag on the producer record;#getEmbeddingWriteCanaryprojects a named non-degradingdisabledstate (scheduling is off until a positive cadence re-arms) instead of letting the old gate truth decay into stale/failure degradation. (2)timeoutMsis stored on the record and re-resolved every arm; the DEFAULT attempt body reads it at call time, so a numeric refresh flows through the preserved body — a providedrunCanaryis documented as opaque with its own bounds (code + JSDoc + spec all say the same thing now). (3) All three timer-clear sites use an explicit null/undefined check, so a scheduler handle of0clears like any other. Specs: disabled projection + re-enable restore, timeout refresh through the preserved default body (bounded timing margins: 5ms → 80ms, pending at +30ms), handle-0 cleared on stop.Test evidence at exact head
1383ebbee3: focused suites 103/103 (gate 21 incl. nested-alias isolation; HealthService 82 incl. disabled/timeout/handle-0 regressions; McpServerToolLimits 13). Full memory-core + shared + tool-limits trees: 1438/1438 green — zero flake-set fallout this run.
