PR Review Summary

Status: Request Changes

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Request Changes
• Rationale: The pure-decider plus ledger-owned fold plus read-only projection is the right decomposition, and the parent remains the explicit runtime producer/consumer owner. Two local state-machine properties fail at the exact head, so this is a bounded repair rather than Drop+Supersede or an out-of-scope wiring demand.

Thanks for keeping the live actuator mutation on #17044 and making the operator surface useful independently. The current decider does not actually behave per target once verdicts interleave, and the fold treats a duplicate freeze record as a true thaw→refreeze cycle.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: Issue #17403 and parent #17044; the seven-file changed-surface list; current dev healActionDispatch, healSystemicCircuit, healEventLedgerStore, freezeReprobeRunner, and DeploymentStateBridgeService; raw memory 4e494fa6-f4b1-4cff-9e33-7aa31ba8ce99 from origin session 8cbd588b-be06-4a56-9997-1058f2a3a07b; exact source and green CI at a0cb2d2bfc870d6dcddb71688b58490584bd760a.
• Expected Solution Shape: A pure per-target futility decider must fail open on untrustworthy input, ignore unrelated targets, and distinguish no-remedy from ineffective-remedy. The ledger-owning fold must derive idempotent freeze transitions and bounded thaw tiers; the projection must remain read-only. This leaf must not invent a second freeze vocabulary or hardcode the future producer.
• Patch Verdict: Placement and bounds match the expected shape. Exact execution contradicts two core properties: unrelated targets break each other’s streaks, and duplicate active freeze rows escalate the tier.
• Premise Coherence: Coheres with verify-before-assert and the flat peer model: the split is explicit, #17044 remains the authority for runtime wiring, and no claim is made that this leaf alone stops evaluation. The two state-machine defects are local rather than premise-level.

🔬 Depth Floor

Challenge OR documented search (per guide §7.1):

• Challenge: The parent contract is per (target, actionClass), but decideFutilityFreeze walks the global tail and stops on the first different target. With five unchanged verdicts for A and five for B interleaved, the exact function reports verdict-changed/streak 1; pre-filtering either target reports freeze/streak 5. Separately, foldFutilityFreezeState increments tier on every freeze row, so two duplicate freeze records without any thaw produce tier 2—the same result as a real thaw→refreeze.

Rhetorical-Drift Audit (per guide §7.4):

• PR description: “keys on consecutive identical verdicts” omits that another target’s row breaks the supposedly per-target streak
• Anchor & Echo summaries: placement and fail-open polarity match the code
• [RETROSPECTIVE] tag: N/A
• Linked anchors: #17044 and the ledger vocabulary establish the claimed split

Findings: Required Actions 1 and 2 restore the stated per-target and refreeze semantics.

🧠 Graph Ingestion Notes

• [KB_GAP]: N/A — the ticket and parent already state the per-target breaker model.
• [TOOLING_GAP]: Every decider fixture uses one target, and every tier fixture uses a clean freeze→unfreeze→freeze sequence; neither suite carries the adversarial interleaving/duplicate-transition controls.
• [RETROSPECTIVE]: A breaker is the polarity inverse of an action gate: malformed evidence must not silence healing. Its durable fold must also be idempotent under duplicate transition records.

N/A Audits — 📡 🔗

N/A across listed dimensions: this PR does not change MCP descriptions, skills, startup substrate, or a cross-skill convention.

🎯 Close-Target Audit

• Close-targets identified: #17403
• #17403 is an open bug leaf, not epic-labeled
• #17044 remains a non-closing reference and owns the producer, consumer gate, and thaw execution

Findings: Pass.

📑 Contract Completeness Audit

• Originating ticket contains a Contract Ledger matrix
• Implemented decider/fold match the per-target and refreeze contract

Findings: Drift at healActionDispatch.mjs:345-355 and healEventLedgerStore.mjs:364-380. The first treats another target as a verdict change; the second advances a tier without an intervening thaw.

🪜 Evidence Audit

• PR body contains an Evidence: L3 → L3 declaration
• Runtime producer/consumer residual is named on open parent #17044
• The projection has independent value because production already emits freeze/unfreeze lifecycle rows
• Pure-function evidence covers mixed-target and duplicate-transition controls

Findings: L3 is achievable and appropriate, but the current exact-head evidence omits the two failing properties.

🧪 Test-Evidence & Location Audit

• Execution evidence: all current required checks green at a0cb2d2bfc870d6dcddb71688b58490584bd760a; author receipts cover memory-core, orchestrator, and bridge suites
• Reviewer falsifier: imported the exact-head pure functions from an isolated archive. Mixed A/B verdicts returned freeze=false, status=verdict-changed, streak=1 while each per-target control returned freeze=true, streak=5. Duplicate freeze(A),freeze(A) returned tier=2, identical to freeze→unfreeze→freeze.
• Test location: added arms live in the canonical helper/bridge unit surfaces

Findings: Falsifiers failed; both properties need red-proof arms.

📋 Required Actions

To proceed with merging, please address the following:

• P1 — make the per-target boundary mechanical. A different target must not break this target’s consecutive run. Either group/filter inside the decider or require/enforce an explicit target boundary; do not leave correctness to an unwritten future-caller prefilter. Add the interleaved A/B red-proof where both targets reach threshold independently.
• P1 — make duplicate freeze transitions idempotent. A tier may advance only after the target was actually cleared and then frozen again; a second freeze row while already active may refresh evidence/time but must not become a refreeze. Add duplicate-freeze and true thaw→refreeze controls. While touching the contract, include maxThawQuietMs in the exported bounds JSDoc type.

📊 Evaluation Metrics

Verdict weights: 30% premise / right thing, 30% architecture + placement, 30% diff correctness, 10% AC/audit sanity.

• [ARCH_ALIGNMENT]: 92 - The decider stays pure, the fold stays beside the ledger vocabulary, and the bridge stays read-only; the parent retains runtime authority.
• [CONTENT_COMPLETENESS]: 82 - The ticket/PR explain the split and caps clearly, but the per-target assumption is not encoded and the thaw-bounds type omits the new ceiling.
• [EXECUTION_QUALITY]: 48 - Green CI covers the nominal paths, but multi-target traffic suppresses the breaker and duplicate records over-escalate containment.
• [PRODUCTIVITY]: 62 - The operator surface and pure primitives exist, but the breaker does not yet satisfy its per-target contract under realistic interleaving.
• [IMPACT]: 86 - This decides whether the immune system stops a no-progress loop without silencing unrelated or recoverable healing.
• [COMPLEXITY]: 78 - Seven files span pure decision, durable fold, snapshot projection, retry-bound classification, and three test surfaces.
• [EFFORT_PROFILE]: Heavy Lift - High-impact state-machine work with durable transition semantics and a deliberately staged runtime handoff.

Both repairs are local to the pure functions and their specs. Re-request this seat at the repaired exact head.
