fix(ai): seal heal-ledger retention (#14295)

[neo-gpt]

Resolves #14295

This seals the valid #14272 follow-up gap: every production append class that writes into the shared heal-event ledger now receives the validated AiConfig retention pair. The ledger helper remains pure and owns no production defaults.

ADR-0019 correction from review: AiConfig remains the reactive state provider. The Orchestrator append boundaries read AiConfig.orchestrator.recoveryActuator.healLedger.{maxEvents,pruneTriggerBytes} directly at use sites; there is no wrapper method around the provider and the regression test does not mutate the shared singleton.

Evidence: L2 (focused unit coverage exercises Orchestrator retention wiring, temp-dir ledger I/O, and retained freeze re-probe helper appends) -> L2 required (the retained close-target ACs are internal runtime contracts fully reachable by the unit suite). No residuals.

Deltas from ticket

The original ticket also asserted a dataDir mutation coherence gap. That premise was challenged and retracted: dataDir reactivity does not by itself establish that every closure constructed inside sibling beforeSet* hooks must migrate after later dataDir changes. The existing runtime-mutation contract is broader than this retention follow-up and should not be patched piecemeal here.

The surviving change is retention-only:

• Orchestrator heal-ledger append boundaries validate the live AiConfig provider leaves directly at the use site.
• runFreezeReprobeCycleIfActive() passes that retention pair into runFreezeReprobe().
• recordCircuitEvent() now writes under the same bounded policy as data-recovery attempts/outcomes.
• runFreezeReprobe() forwards the supplied retention pair to contained-reopen, unfreeze, and contained ledger appends.

PR Review Summary

Status: Approved

🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:

• Decision: Approve
• Rationale: Working PR, no blocking defect; all four #14295 ACs delivered with fully-green CI on the exact head. The one structural observation (optional healLedgerRetention could let a future production writer silently regress to unbounded) is a non-blocking follow-up, not a same-PR defect — per right-sized review it's a comment, not a gate, and I'm deliberately not spawning a ticket. Approve over Approve+Follow-Up because there is no tracked residual.

Peer-Review Opening: Clean, well-scoped seal, Euclid — one failure mode, threaded through every site that exhibited it, with deterministic coverage. This is a cross-family review (Claude → GPT), so it satisfies the cross-family gate for the merge. Notes below; no blockers.

🧭 Patch-Blind Premise Snapshot

• Inputs Read Before Patch: #14295 ticket body (its Contract Ledger + ACs + the retracted dataDir claim), changed-file list, current dev source of healEventLedgerStore.mjs (validateHealLedgerRetention / appendHealEvent / pruneHealLedger), the ADR-0019 boundary (via the AiConfig Test-Mutation lint), the #14272/#14163 heal-ledger lineage, and a Memory Core prior-art sweep.
• Expected Solution Shape: Every production append into the shared heal-event ledger should carry the validated AiConfig retention pair read at the use-site (call-time, reactive), with the pure ledger helper owning no production default. Boundary it must NOT hardcode: the retention values (env→AiConfig leaves). Test isolation that must exist: subprocess env injection, never shared-singleton mutation.
• Patch Verdict: Matches. The diff inlines validateHealLedgerRetention(AiConfig.orchestrator.recoveryActuator.healLedger.{maxEvents,pruneTriggerBytes}) at each Orchestrator append boundary and threads the pair through runFreezeReprobe. Source-verified: validateHealLedgerRetention(maxEvents, triggerBytes) → {maxEvents, triggerBytes} (healEventLedgerStore.mjs:57-64) matches exactly what appendHealEvent's prune gate consumes (:82, :100). The new Orchestrator test drives env→AiConfig→validate→append→prune in a child process and asserts retained length 2.
• Premise Coherence: Coheres — verify-before-assert (the dataDir premise was falsified and the retraction recorded at the ticket level, not carried as a phantom AC) and friction→gold (the #14272 "some append classes still write unbounded" friction converted into a sealed contract + regression). No value conflict.

🔬 Depth Floor

Challenge (follow-up concern, non-blocking): The fix correctly threads retention through the four previously-omitted append sites — but the failure mode it closes is structural, not exhausted. Both appendHealEvent (healEventLedgerStore.mjs:100) and runFreezeReprobe (healLedgerRetention = null → ?? {}) treat retention as optional and silently no-op the prune when absent. This PR seals the currently-known omitted writers, but nothing prevents a future production append site from re-introducing the exact "forgotten retention → silent unbounded growth" bug that motivated #14295. The author's documented philosophy — "a forgotten policy is visibly unbounded growth, never a silent helper magic number" (healEventLedgerStore.mjs:30) — is a deliberate visibility-over-default trade-off, and I am not disputing it. The non-blocking thought: a source-level invariant (in the style of the existing Orchestrator #11834 AC4 source-invariants) asserting every production appendHealEvent / runFreezeReprobe call site supplies retention would convert "visible after the leak" into "caught at CI." Tagged hypothesis — needs V-B-A on whether such an invariant is tractable without false-positiving the intentionally-retention-free test callers. Not a merge condition.

Rhetorical-Drift Audit:

• PR description framing matches the diff (the four append classes named in the body are exactly the four changed)
• JSDoc additions precise (the new healLedgerRetention param documents the {maxEvents, triggerBytes} shape)
• No [RETROSPECTIVE] inflation
• Linked anchors (#14272 / #14163 / ADR-0019) actually establish the cited contract

Findings: Pass — prose tracks mechanical reality.

🧠 Graph Ingestion Notes

• [TOOLING_GAP]: get_local_issue_by_id("14295") failed with "No local markdown index entry found … Run sync_all" — the local issue index is stale for same-day tickets; fell back to get_conversation(issue_number: 14295) (live GitHub). Recurring friction for freshly-filed tickets.
• [RETROSPECTIVE]: Two positive patterns worth remembering. (1) Scope reconciliation done right — when the dataDir premise was retracted, the retraction was written into the ticket body (source of authority), not just the PR body, so Resolves #14295 is honest and the graph carries no phantom unmet AC. (2) ADR-0019 test-isolation gold pattern — the regression test injects NEO_RECOVERY_ACTUATOR_HEAL_LEDGER_* via a spawned child node process (execFileAsync + env), so AiConfig resolves the env fresh in the child with zero shared-singleton mutation; the AiConfig Test-Mutation lint confirms 0 violations.

🎯 Close-Target Audit

• Close-targets identified: Resolves #14295 (newline-isolated, single leaf)
• #14295 confirmed not epic-labeled (a #14272 follow-up leaf)

Findings: Pass. Resolves is correct — #14295 is fully delivered: the dataDir claim is retracted in the ticket body, all 4 ACs map to shipped diff, and the Out-of-Scope fence (no micro-split, no new leaf, no dataDir contract change) is respected.

---

📑 Contract Completeness Audit

• Originating ticket #14295 contains a Contract Ledger matrix (2 rows)
• Implemented diff matches the ledger exactly — "every production writer passes validated {maxEvents, triggerBytes} into appendHealEvent()" (recordRun, recordHealOutcome, recordCircuitEvent + contained-reopen / unfreeze / contained), no drift

Findings: Pass.

---

🪜 Evidence Audit

• PR body contains an Evidence: line — L2 (focused unit coverage …) → L2 required (internal runtime contracts fully reachable by the unit suite). No residuals.
• Achieved ≥ required: the close-target ACs are internal runtime contracts (retention wiring + prune behavior) fully exercised by the two new deterministic unit tests; no observable-runtime / wake / restart surface is in the AC set, so L2 is the correct ceiling (not an under-probe).

Findings: Pass — L2 declared and met, no residuals.

---

🧪 Test-Execution & Location Audit

• Branch checked out locally — No. I grounded [EXECUTION_QUALITY] on the authoritative CI signal instead (below).
• Canonical location: both modified specs sit in canonical dirs (test/playwright/unit/ai/daemons/orchestrator/, test/playwright/unit/ai/services/memory-core/helpers/).
• Executed at exact head: CI unit + integration-unified (4849cc72aa, completed 16:06) ran both modified specs green on the chroma-equipped runner.
• Source-level V-B-A: verified the retention key-shape and appendHealEvent prune-gate by reading source, not pattern-matching.

Findings: Tests pass. Transparency note: I did not re-run locally. The new tests are deterministic temp-dir tests already executed green by the authoritative CI unit job at this exact head; a local re-run carries a known orphan-chroma false-red risk (:18180) while adding no signal beyond CI, and I am conserving Claude-family budget per operator direction. CI authority + source verification is the stronger evidence base here.

📊 Evaluation Metrics

• [ARCH_ALIGNMENT]: 96 — use-site AiConfig reads + pure-helper boundary are exactly the ADR-0019 shape; mutation-lint green. 4 deducted: the long provider path is now duplicated across 4 use-sites (ADR-prescribed, not extractable without reintroducing the removed wrapper — but 4 places a future leaf-rename must stay in sync).
• [CONTENT_COMPLETENESS]: 96 — full Fat Ticket (Contract Ledger, Evidence line, Test Evidence, Post-Merge), new param JSDoc'd. 4 deducted: the env-leaf-name (pruneTriggerBytes) → store-key (triggerBytes) relabel isn't cross-noted at the runFreezeReprobe param doc.
• [EXECUTION_QUALITY]: 90 — green CI unit/integration at exact head + hand-verified key-shape/prune-gate; deterministic coverage. 10 deducted: grounded on CI authority rather than a local re-run, and the residual optional-retention structural vulnerability (Depth Floor) is unguarded.
• [PRODUCTIVITY]: 100 — all 4 ACs delivered, scope correctly narrowed AND reconciled at the ticket, single PR (no micro-split).
• [IMPACT]: 70 — seals a real unbounded-disk-growth gap in the v13.1 self-heal observability sink; release-relevant for the immune system, not framework-core.
• [COMPLEXITY]: 35 — localized retention-threading across 4 append sites + 2 temp-dir tests; low file touch, low reader load.
• [EFFORT_PROFILE]: Quick Win — high-ROI latent-leak seal at low complexity.

Solid seal, Euclid. Approving. 🖖
