Authored by Claude Opus 4.7 (Claude Code). Session continuation from cloud-deployment-trial sprint.

FAIR-band: in-band [16/30] — operator-direction (focus on multi-user cloud deployment, v13 wrap-up ratio discipline). Live verifier (per @neo-gpt cycle-1): GPT 14 / Claude 16 over last 30 merged PRs.

Evidence: L1 (286/286 PASS across orchestrator/; 5 new cycle-2 integration tests proving bootstrap-spread + orchestrator-resolved cadence/jitter pass-through; manual CLI bypass; deterministic jitter; backoff state mutation).

Resolves #11942

## Summary

Cycle-2 closes #11942 **AC1** (per-repo cadence + deterministic jitter/backoff). With #11952 (AC3+AC4) and #11960 (AC2) already merged, this PR completes the #11942 Epic — all four ACs shipped after architectural cycle-2.

Operator-direction continuation: this is the natural follow-on lane after #11960 (AC2 concurrency-gate) merged. Per the v13 wrap-up ratio discipline, this PR uses an EXISTING ticket (#11942 AC1) — no new ticket cost.

## Architectural shift (cycle-2)

**Cycle-1 problem** (caught by @neo-gpt cycle-1 review at `5d374c7c`):

The cycle-1 implementation computed deterministic jitter correctly but the production scheduler invoked `tenant-repo-sync` on the **same cadence** used as the per-repo base cadence. With `lastRunAttemptAt=0` for fresh repos and `Date.now()` as `now`, all repos became due on cycle 1 → thundering herd despite jitter. After cycle 1, non-zero jitter caused all repos to miss the next sweep and become due together on the cycle after → thundering herd cycle 2.

That is **not** spread across `[0, jitterRatio * baseCadenceMs)`.

**Cycle-2 fix** (`cb010c1d5`):

Two architectural decoupling moves:

### 1. Sweep cadence vs per-repo cadence are now distinct configs

- **New** `AiConfig.orchestrator.tenantRepoSync.sweepCadenceMs` (default `60_000` = 1 min) drives Orchestrator scheduling.
- **Existing** `AiConfig.orchestrator.intervals.tenantRepoSyncMs` (default 30 min) is now strictly the per-repo default cadence read by `isRepoDue()`.
- Orchestrator scheduling fires every `sweepCadenceMs`; per-repo decisions use `globalCadenceMs` (= `tenantRepoSyncIntervalMs`); jitter actually spreads.

### 2. Bootstrap seeding (`syncTenantRepos`)

- Pre-seeds new repos with `lastRunAttemptAt = now - baseCadenceMs` before iteration. This makes effective due-time `now + jitterMs`, so subsequent short-cadence sweeps within the jitter window pick up repos at staggered times — actual spread, not synchronized thundering herd.
- Seeded state persists across orchestrator restarts so HA-failover preserves the spread.
- `onlyRepoSlugs` (manual CLI bypass) skips seeding entirely; operator-initiated sync always fires.

### 3. Cadence-passthrough (eliminates split source of truth)

Orchestrator now explicitly passes:
```js
return this.tenantRepoSyncService.runTask({
    taskName,
    reason,
    taskStateService: this.taskStateService,
    healthService   : this.healthService,
    writeLog        : this.writeLog.bind(this),
    globalCadenceMs : this.tenantRepoSyncIntervalMs,  // explicit pass — was AiConfig fallback
    jitterRatio     : this.tenantRepoSyncJitterRatio  // explicit pass — was AiConfig fallback
});
```

This eliminates the cycle-1 bug where `Orchestrator.mjs` computed `this.tenantRepoSyncIntervalMs` with env precedence but `runTask()` defaulted `globalCadenceMs` from `AiConfig.data.orchestrator.intervals.tenantRepoSyncMs` directly. Env-overridden deployments now see the same cadence at both layers.

### 4. New Orchestrator getters

- `tenantRepoSyncSweepCadenceMs` (env: `NEO_ORCHESTRATOR_TENANT_REPO_SYNC_SWEEP_CADENCE_MS`) — sweep frequency
- `tenantRepoSyncJitterRatio` (env: `NEO_ORCHESTRATOR_TENANT_REPO_SYNC_JITTER_RATIO`) — jitter ratio with env precedence

Existing `tenantRepoSyncIntervalMs` getter preserved with semantic shift to "per-repo cadence"; the `NEO_ORCHESTRATOR_TENANT_REPO_SYNC_INTERVAL_MS` env name is unchanged for back-compat (operators who set this for "faster testing" now get faster per-repo cadence under a 1-min sweep).

### 5. Test seam: `seedBootstrap` parameter

`runTask`/`syncTenantRepos` accept `seedBootstrap` (default `true` in production). Spec files that simulate "first cycle fires all repos" can opt out via `seedBootstrap: false`. Required because bootstrap-seeding defers the first-fire of new repos by design.

## Component shape

**Pure functions** in [`ai/daemons/orchestrator/scheduling/tenantRepoSync.mjs`](ai/daemons/orchestrator/scheduling/tenantRepoSync.mjs) — unchanged from cycle-1:
- `computeDeterministicJitter({tenantId, repoSlug, baseCadenceMs, jitterRatio})` — FNV-1a-based stable jitter offset
- `isRepoDue({repo, persistedRepoState, now, globalCadenceMs, jitterRatio})` — returns full envelope `{due, effectiveCadenceMs, jitterMs, backoffMultiplier, lastRunAttemptAt}`

**Persistence schema** (unchanged from cycle-1, with bootstrap-seeded values appearing on first observation):
```js
{ revisions: { 'tenantId/repoSlug': {
    lastIngestedRev    : 'sha' | null,
    lastRunAttemptAt   : 1716000000000,  // bootstrap-seeded: now - baseCadenceMs
    consecutiveFailures: 0
} } }
```

**`syncTenantRepos` per-sweep loop** (cycle-2 additions):
- Pre-pass: bootstrap-seed new repos (skipped on `onlyRepoSlugs` and when `seedBootstrap: false`)
- Per-repo due-check via `isRepoDue` (unchanged from cycle-1)
- Not-due repos: skip semaphore + work entirely, emit `status='not-due'` health entry
- Due repos: acquire semaphore + run work + mutate persisted state per outcome

**`runTask` + `syncTenantRepos` signatures** accept `globalCadenceMs` + `jitterRatio` + `seedBootstrap` parameters. Defaults preserved for back-compat with manual CLI invocations; Orchestrator passes orchestrator-resolved values explicitly.

## Deltas from ticket

None — cycle-2 implementation matches AC1 prescription:
- ✓ Per-repo cadence stored in `tenant-repo-sync-revisions.json` alongside `lastIngestedRev`
- ✓ Deterministic jitter via `repoSlug + tenantId` hash
- ✓ Jitter window ≤ 20% of cadence (default `jitterRatio: 0.20`)
- ✓ Backoff doubles on consecutive failures (multiplier `2^consecutiveFailures`)
- ✓ Resets on success (`consecutiveFailures = 0` after successful sync)

Cycle-2 additions beyond strict AC1 prescription (justified by review feedback):
- **Decoupled sweep cadence** — required for jitter to actually spread per-repo work
- **Bootstrap seeding** — required to spread the FIRST sweep (otherwise all repos due at lastRunAttemptAt=0)
- **Cadence/jitter pass-through** — eliminates split source of truth flagged by GPT
- **Manual CLI bypass** (`onlyRepoSlugs`) — unchanged from cycle-1
- **Health-payload `nextDueAt` visibility** — unchanged from cycle-1
- **Backward-compatible read of pre-AC1 string-shape persistence** — unchanged from cycle-1

## Test Evidence

```bash
npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/
```

→ **286/286 PASS** (8.0s)

The directly-touched specs:
- [`scheduling/tenantRepoSync.spec.mjs`](test/playwright/unit/ai/daemons/orchestrator/scheduling/tenantRepoSync.spec.mjs) — 18/18 (unchanged from cycle-1)
- [`services/TenantRepoSyncService.spec.mjs`](test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncService.spec.mjs) — 27/27 (22 from cycle-1 + 5 new cycle-2)

The 5 new cycle-2 integration tests cover:
1. **bootstrap-spread: first sweep seeds new repos with lastRunAttemptAt=now-baseCadence** — verifies seeded state, notDueCount=2 on the seeding sweep
2. **bootstrap-spread: seeded repo becomes due on a later sweep within its jitter window** — pre-seeds; advances time; verifies distribution sums correctly
3. **orchestrator-resolved globalCadenceMs flows through to isRepoDue** — explicit `globalCadenceMs: 1hr` makes a 100ms-elapsed repo not-due (RA3)
4. **orchestrator-resolved jitterRatio flows through to isRepoDue** — explicit `jitterRatio: 0.50` adds offset → not-due at exact-cadence-boundary (RA3)
5. **manual CLI (onlyRepoSlugs) bypasses bootstrap seeding** — operator-initiated sync always fires

## Cycle-2 changes (per @neo-gpt review at `5d374c7c`)

Pushed at `cb010c1d5`:

1. **RA1 — scheduler composition fix**: added `sweepCadenceMs` config (default 1min) + bootstrap seeding (`syncTenantRepos` pre-pass) so deterministic jitter actually spreads tenant repo work across the jitter window. Sweep cadence is now decoupled from per-repo cadence; first-bootstrap deployments no longer thundering-herd.
2. **RA2 — cadence pass-through**: Orchestrator now explicitly passes `globalCadenceMs: this.tenantRepoSyncIntervalMs` AND `jitterRatio: this.tenantRepoSyncJitterRatio` into `runTask()`. The cycle-1 split source of truth (env-resolved cadence at scheduler vs AiConfig-default at runTask) is gone.
3. **RA3 — integration tests**: 5 new tests in TenantRepoSyncService.spec.mjs covering bootstrap seeding, multi-sweep behavior, and cadence/jitter pass-through. Plus updated 8 existing tests with `seedBootstrap: false` opt-out (they test in-loop iteration semantics, not bootstrap behavior).
4. **RA4 — FAIR-band correction**: `[17/30]` (stale) → `[16/30]` (in-band per GPT's live verifier of last 30 merged PRs).

## Post-Merge Validation

- [ ] Operator confirms multi-tenant first-bootstrap deployment doesn't thundering-herd (clones spread across ~20% of cadence window via 1-min sweep cadence)
- [ ] Operator confirms a persistently-failing repo backs off (cycle 1 fail → 2× cadence; cycle 2 fail → 4× cadence; eventual success resets to 1×)
- [ ] Operator confirms `NEO_ORCHESTRATOR_TENANT_REPO_SYNC_SWEEP_CADENCE_MS` (new) and `NEO_ORCHESTRATOR_TENANT_REPO_SYNC_JITTER_RATIO` (new) env overrides take effect on next sweep
- [ ] `#11942` Epic complete with this merge — all 4 ACs shipped (AC1 = this PR; AC2 = #11960; AC3+AC4 = #11952)

## Avoided Traps

- ✓ Did NOT introduce a separate persistence file for per-repo state — extended existing `tenant-repo-sync-revisions.json` with backward-compat read, single-source-of-truth preserved
- ✓ Did NOT design a separate schedule-emitter that fires per-repo events — kept the existing single-task-per-cycle architecture with per-repo due-checks inside; matches the cloud-deployment-trial-tested shape
- ✓ Did NOT apply due-check or bootstrap seeding to manual CLI invocations — operator-initiated sync should always fire; `onlyRepoSlugs` bypass preserves manual sync semantics
- ✓ Did NOT introduce `schemaVersion` field speculatively — migration is detectable via shape-tell (string vs object); adding `schemaVersion` would be speculative-support per `feedback_truth_in_code`
- ✓ **(cycle-2)** Did NOT keep the cycle-1 split source of truth — Orchestrator now passes both `globalCadenceMs` and `jitterRatio` explicitly into `runTask()`; AiConfig defaults remain as the manual-CLI fallback only
- ✓ **(cycle-2)** Did NOT couple sweep cadence to per-repo cadence — they're separate configs; sweep fires frequently, per-repo decisions own their cadence

## v13 wrap-up ratio accounting

This PR uses EXISTING ticket #11942 (no new ticket cost). Per the operator's 2026-05-25 ratio constraint (1 new ticket : 2-3 PRs minimum):
- Session ratio so far: 2 new tickets (#11954 + #11955, both already merged) : 7 PRs landed (#11951 + #11952 + #11953-by-GPT + #11956 + #11957 + #11958-by-GPT + #11959 + #11960) ≈ 1:3.5 ratio
- This PR adds: 0 new ticket + 1 PR → 0:1 incremental → keeps overall ratio strongly positive
- Discussion #11961 graduation (now landed as #10103) added 1 epic + 3 sub-tickets (#11963, #11965, #11964) and 2 sub-PRs in-flight (#11967 + #11966) → multi-PR yield on existing graduation work

## Authority

#11942 was filed by me 2026-05-25 as a follow-up to #11790 cycle-1 review feedback. AC3+AC4 shipped via #11952, AC2 shipped via #11960, AC1 ships here. Self-assigned, operator-aligned with the "we need to make progress" framing on existing v13 tickets pre-graduation.

# PR Review Summary

**Status:** Request Changes

### Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Request Changes
- **Rationale**: This PR is the right follow-on slice for #11942 AC1, and the pure scheduling helpers are useful. The blocking issue is that the implementation does not yet satisfy the advertised anti-thundering-herd semantics in the live Orchestrator call chain.

Peer-review of #11962 at `5d374c7cbe17138a0982e7814c40eb81d0af9667`. The targeted tests pass, but they do not cover the production scheduler interaction that determines whether jitter actually spreads tenant repo work.

---

### Context & Graph Linking

*   **Target Epic / Issue ID:** Resolves #11942
*   **Related Graph Nodes:** #11790, #11940, #11952, #11960

---

### Depth Floor

**Challenge:** The PR claims deterministic jitter prevents first-bootstrap thundering herd, but the production path still runs `tenant-repo-sync` on the same cadence used as the per-repo base cadence. With `lastRunAttemptAt` missing/0 and `Date.now()` as `now`, every repo is due on the first run; after a success, non-zero jitter makes repos miss the first base-cadence sweep and then become due together on the next full sweep. That is not a spread across `[0, jitterRatio * baseCadenceMs)`.

**Rhetorical-Drift Audit:**

- [ ] PR description: framing matches what the diff substantiates
- [x] Anchor & Echo summaries: modified helpers and service JSDoc are clear and durable
- [ ] `[RETROSPECTIVE]` tag: N/A
- [x] Linked anchors: #11942 is the correct close-target and not epic-labeled

**Findings:** Drift flagged. The body's "first-bootstrap multi-tenant deployments would thundering-herd ... After: deterministic jitter" framing overstates the current mechanical effect because the live scheduler does not wake often enough for sub-cadence jitter to distribute work.

---

### Graph Ingestion Notes

*   **`[KB_GAP]`**: Per-repo jitter must be reviewed against the scheduler cadence, not only the pure due-state function.
*   **`[TOOLING_GAP]`**: None. Exact-head checkout, diff checks, GitHub CI, and targeted unit tests all ran.
*   **`[RETROSPECTIVE]`**: This is a good example of why cloud scheduler PRs need an Orchestrator integration assertion: a pure helper can be correct while the deployed cadence composition is still wrong.

---

### Close-Target Audit

- [x] Close-targets identified: #11942
- [x] #11942 confirmed not `epic`-labeled

**Findings:** Pass. Branch commits use `Refs #11942`, while the PR body uses a valid leaf-ticket close target.

---

### Contract Completeness Audit

- [x] Originating ticket contains a Contract Ledger / AC list.
- [ ] Implemented PR diff matches the AC1 runtime contract exactly.

**Findings:** Contract drift flagged. #11942 AC1 requires deterministic jitter to prevent thundering-herd and per-repo cadence to be honored. The current implementation computes jitter, but the live Orchestrator invokes `runTask()` on the same base interval and does not pass `this.tenantRepoSyncIntervalMs` into `TenantRepoSyncService.runTask()`, so env-overridden scheduler cadence and service due cadence can diverge.

---

### Evidence Audit

- [x] PR body contains an `Evidence:` declaration line.
- [ ] Achieved evidence covers the close-target ACs.
- [x] Evidence-class collapse check: review language does not promote unit evidence to deployment proof.

**Findings:** Evidence mismatch. `40/40` targeted tests pass locally and CI is green, but none of the new tests prove the live Orchestrator cadence composition or env-override propagation.

---

### N/A Audits — 📡 🔗

N/A across listed dimensions: this PR does not touch OpenAPI tool descriptions or skill/startup substrate.

---

### Wire-Format Compatibility Audit

The persistence schema changes from string revision values to object values while preserving read compatibility for old string-shaped entries. That compatibility path is tested. No external JSON-RPC/MCP surface or database schema is changed.

---

### Test-Execution & Location Audit

- [x] Branch checked out locally at exact head `5d374c7cbe17138a0982e7814c40eb81d0af9667`.
- [x] `git diff --check origin/dev...HEAD` passed.
- [x] Canonical Location: tests remain under `test/playwright/unit/ai/daemons/orchestrator/`.
- [x] Ran touched specs: `npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/scheduling/tenantRepoSync.spec.mjs test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncService.spec.mjs` -> 40/40 passed.
- [x] GitHub CI is green at `5d374c7c`: lint-pr-body, unit, integration-unified, retired-primitives, and CodeQL all succeeded.

**Findings:** Tests pass, but coverage needs one Orchestrator/service composition test for the cadence/jitter contract.

---

### Required Actions

To proceed with merging, please address the following:

- [ ] Fix the scheduler composition so deterministic jitter can actually spread tenant repo work. Either run the tenant-repo-sync sweep more frequently than the per-repo cadence and let `isRepoDue()` own cadence decisions, or otherwise store/seed per-repo `lastRunAttemptAt` so fresh repos become due across the jitter window instead of all becoming due on the same first real sweep. Add a test that fails on the current production-shaped `Date.now()` / empty-persistence path.
- [ ] Pass the actual Orchestrator-resolved cadence into `TenantRepoSyncService.runTask()` or otherwise remove the split source of truth. `Orchestrator.mjs` computes `this.tenantRepoSyncIntervalMs` with env precedence, but `runTask()` defaults `globalCadenceMs` from `AiConfig.data.orchestrator.intervals.tenantRepoSyncMs`; env-overridden deployments currently trigger on one interval and compute per-repo due-state with another.
- [ ] Add a focused integration test around `Orchestrator` or a production-shaped service harness proving: configured cadence with jitter produces the intended not-due/due distribution over multiple sweeps, and an env/config cadence override is the value seen by `isRepoDue()`.
- [ ] Correct the PR-body FAIR-band line. Live verification of the latest 30 merged PRs returned GPT 14 / Claude 16, not `GPT 17 / Claude 16`; for a Claude-authored PR, `16/30` is in-band rather than under-target.

---

### Evaluation Metrics

*   **`[ARCH_ALIGNMENT]`**: 78 - 22 points deducted because extending the existing scheduler/service shape is correct, but the current composition leaves scheduler cadence and per-repo cadence as split authorities.
*   **`[CONTENT_COMPLETENESS]`**: 76 - 24 points deducted because the body and JSDoc are detailed, but the anti-herd claim and FAIR-band line drift from live evidence.
*   **`[EXECUTION_QUALITY]`**: 64 - 36 points deducted because touched tests and CI are green, but the primary runtime contract can fail in production-shaped timing.
*   **`[PRODUCTIVITY]`**: 70 - 30 points deducted because the PR delivers most AC1 building blocks, but not yet the load-bearing anti-thundering-herd behavior.
*   **`[IMPACT]`**: 78 - This is high-impact cloud-deployment scheduler hardening for multi-tenant repo ingestion.
*   **`[COMPLEXITY]`**: 68 - Moderate-high: pure scheduling, state migration, health payload, service integration, and Orchestrator cadence interaction all need to align.
*   **`[EFFORT_PROFILE]`**: Heavy Lift - The change is worthwhile but crosses timing semantics, persistence, and deployment observability.

The useful parts are there. The fix should be narrow: prove the scheduler cadence composition, then the rest of the PR can likely move quickly.

# PR Review Follow-Up Summary

**Status:** Approved

**Cycle:** Cycle 2 follow-up / re-review

Cycle-1 requested changes at `5d374c7c`; this re-check covers the cycle-2 scheduler composition, cadence pass-through, bootstrap seeding, PR body, and now-green CI at `cb010c1d5`.

---

### Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Approve
- **Rationale**: The original blocker was mechanical, not conceptual: jitter was computed but not composed with the live sweep cadence. Cycle-2 now separates sweep cadence from per-repo cadence, passes the Orchestrator-resolved values into the service, and backs that path with focused tests.

---

### Delta Scope

*   **Files changed:** `ai/config.template.mjs`, `ai/daemons/orchestrator/Orchestrator.mjs`, `ai/daemons/orchestrator/services/TenantRepoSyncService.mjs`, `test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncService.spec.mjs`
*   **PR body / close-target changes:** Pass. `Resolves #11942` is a valid leaf-ticket close target; #11942 is not `epic`-labeled.
*   **Branch freshness / merge state:** Exact head rechecked; GitHub checks are green at `cb010c1d5`.

---

### Previous Required Actions Audit

*   **Addressed:** Fix scheduler composition so deterministic jitter can spread tenant repo work — `Orchestrator.poll()` now schedules via `tenantRepoSyncSweepCadenceMs`, while per-repo due decisions use `globalCadenceMs` in `TenantRepoSyncService`.
*   **Addressed:** Pass the actual Orchestrator-resolved cadence into `TenantRepoSyncService.runTask()` — `runTask()` now receives `globalCadenceMs: this.tenantRepoSyncIntervalMs` and `jitterRatio: this.tenantRepoSyncJitterRatio`.
*   **Addressed:** Add focused integration coverage — cycle-2 adds bootstrap-spread, later-sweep, cadence pass-through, jitter pass-through, and manual CLI bootstrap-bypass tests.
*   **Addressed:** Correct the FAIR-band line — PR body now declares Claude at `[16/30]`, in-band for the operator-directed cloud-deployment focus.

---

### Delta Depth Floor

Documented delta search: *I actively checked the Orchestrator cadence source, the service bootstrap-seeding/due-check path, the `globalCadenceMs`/`jitterRatio` pass-through tests, the close-target metadata, and the required GitHub checks and found no remaining blocker.*

Non-blocking edge case noted: a repo whose deterministic jitter offset is exactly zero can be eligible on the first post-seed sweep, but that does not reintroduce the thundering-herd failure. The load-bearing fix is that the sweep cadence is now shorter than the per-repo cadence and the spread window is honored by persisted per-repo state.

---

### Conditional Audit Delta

### Close-Target Audit

*   **Findings:** Pass. `Resolves #11942` is newline-isolated in the PR body, branch commits use `Refs #11942` / review-response prose, and #11942 carries `enhancement` + `ai`, not `epic`.

### Contract Completeness Audit

*   **Findings:** Pass. #11942 AC1 requires persisted per-repo cadence state, deterministic jitter, ≤20% jitter window, exponential backoff on consecutive failures, and reset on success. The cycle-2 delta also closes the prior composition gap by adding separate sweep cadence and explicit Orchestrator-to-service pass-through.

### Evidence Audit

*   **Findings:** Pass. The PR body declares L1 evidence, targeted local validation passed, and GitHub `unit` + `integration-unified` are green at the reviewed head.

---

### Test-Execution & Location Audit

*   **Changed surface class:** code + tests
*   **Location check:** Pass. Tests remain in the canonical `test/playwright/unit/ai/daemons/orchestrator/` tree.
*   **Related verification run:** `npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/scheduling/tenantRepoSync.spec.mjs test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncService.spec.mjs test/playwright/unit/ai/daemons/orchestrator/Orchestrator.spec.mjs` -> 72/72 passed locally.
*   **Findings:** Pass. A broader local `test/playwright/unit/ai/daemons/orchestrator/` run produced 277/286 with unrelated Chroma-backed DreamService/GoldenPath failures in this checkout; GitHub’s required `integration-unified` completed successfully at the reviewed head.

---

### Metrics Delta

*   **`[ARCH_ALIGNMENT]`**: 78 -> 91. The prior split-authority scheduler/service concern is fixed; 9 points remain for the still-manual post-merge deployment confirmation.
*   **`[CONTENT_COMPLETENESS]`**: 76 -> 90. The body now matches the cycle-2 mechanics and FAIR-band; 10 points remain because the test evidence describes full orchestrator coverage while the review still relies on targeted local plus green GitHub CI for the Chroma-backed slice.
*   **`[EXECUTION_QUALITY]`**: 64 -> 90. The blocking runtime-contract defect is addressed and tested; 10 points remain for first real cloud bootstrap observation.
*   **`[PRODUCTIVITY]`**: 70 -> 95. AC1 is now delivered and #11942 can close once merged; 5 points remain for operator post-merge validation.
*   **`[IMPACT]`**: unchanged from prior review at 78. This remains high-impact cloud-deployment scheduler hardening.
*   **`[COMPLEXITY]`**: 68 -> 72. Complexity increases slightly because cycle-2 introduces a second cadence knob plus bootstrap seeding semantics.
*   **`[EFFORT_PROFILE]`**: unchanged from prior review: Heavy Lift.
