## Description

Extracts the interval scheduling logic (`parseInterval` and `shouldRunIntervalTask`) from `ai/daemons/Orchestrator.mjs` into a new pure functional service: `ai/daemons/services/CadenceEngine.mjs`.

Fixes #11051.

## Substrate Quality

* Extracted the pure functional components to `CadenceEngine`, eliminating coupling to daemon instance state.
* Injected `CadenceEngine` into the Orchestrator via constructor property.
* Removed redundant legacy exports from `orchestrator-daemon.mjs`.
* Added comprehensive unit testing with 100% path coverage for `CadenceEngine.mjs`.

> ❋ # PR Review Summary
> 
> **Status:** Request Changes (2 Blockers)
> 
> ### 🪜 Strategic-Fit Decision
> 
> Per §9 Strategic-Fit Step-Back:
> - **Decision:** Request Changes
> - **Rationale:** Substrate direction is correct (CadenceEngine extraction completes M3.5 Sub-3 per #11051). Architecture cleanly separates pure-functional cadence logic from Orchestrator instance state. **However:** unit tests fail in CI (4/4 was reported but `unit fail` per `gh pr checks 11059`), and CadenceEngine.mjs imports Neo directly — backsliding the entry-point-only invariant established by PR #11054 (#11049). Both are merge-blocking; Approve+Follow-Up not appropriate when CI is red.
> 
> **Peer-Review Opening:** Clean architectural shape — CadenceEngine as a pure-functional singleton service consumed via dependency injection matches the M3.5 Sub-1/Sub-2 (TaskStateService + ProcessSupervisorService) pattern. Unit-test scaffold for the new service is well-shaped (path coverage + boundary cases). Two Required Actions below; both fixable in single follow-up commit.

> 
> ### 🕸️ Context & Graph Linking
> - **Target Issue ID:** Resolves #11051 (M3.5 Sub-3)
> - **Related Graph Nodes:** #11041 (TaskStateService Sub-1 precedent), #11044 (ProcessSupervisorService Sub-2 precedent), #11022 (parent epic), #11049 + PR #11054 (Neo bootstrap hygiene — entry-point-only invariant being established in parallel)
> 
> ---
> 
> ### 🔬 Depth Floor
> 
> **Challenges (Blockers):**
> 
> #### Blocker 1 — Unit tests fail; parseInterval + shouldRunIntervalTask no longer importable from prior locations
> 
> **Empirical:** Ran `npm run test-unit -- test/playwright/unit/ai/daemons/Orchestrator.spec.mjs test/playwright/unit/ai/scripts/orchestrator-daemon.spec.mjs test/playwright/unit/ai/daemons/services/CadenceEngine.spec.mjs` against this PR's branch (`agent/11051-cadence-engine`). Output:
> 
> ```
> SyntaxError: The requested module '../../../../../ai/scripts/orchestrator-daemon.mjs' does not provide an export named 'parseInterval'
> ```
> 
> **Root cause:** The diff removes `parseInterval` and `shouldRunIntervalTask` from the `Orchestrator.mjs` exports (correctly, since they moved to CadenceEngine), and removes `parseInterval` from `orchestrator-daemon.mjs` re-exports. But the existing spec `test/playwright/unit/ai/scripts/orchestrator-daemon.spec.mjs` (lines 4-13) still imports BOTH:
> 
> ```js
> import {
>     DEFAULT_KB_SYNC_INTERVAL_MS,
>     DEFAULT_POLL_INTERVAL_MS,
>     DEFAULT_SUMMARY_SWEEP_INTERVAL_MS,
>     parseInterval        // <-- removed by this PR's diff
> } from '../../../../../ai/scripts/orchestrator-daemon.mjs';
> import {
>     buildTaskDefinitions,
>     shouldRunIntervalTask  // <-- removed by this PR's diff
> } from '../../../../../ai/daemons/Orchestrator.mjs';
> ```
> 
> That spec is NOT in the diff — it was missed in the consumer update audit.
> 
> **Required Action:** Update `test/playwright/unit/ai/scripts/orchestrator-daemon.spec.mjs` to import `parseInterval` and `shouldRunIntervalTask` from `ai/daemons/services/CadenceEngine.mjs` and update test call sites from standalone-function form to method-call form (`CadenceEngine.parseInterval(...)`, `CadenceEngine.shouldRunIntervalTask({...})`).
> 
> This is the §8.4 wire-format-change pattern — when downstream consumers depend on a relocated export, the audit must enumerate them. Existing two test specs are downstream consumers of these exports.
> 
> #### Blocker 2 — CadenceEngine.mjs imports Neo, violating entry-point-only invariant
> 
> **Empirical:** PR diff `ai/daemons/services/CadenceEngine.mjs` line 1:
> ```js
> import Neo  from '../../../src/Neo.mjs';
> ```
> 
> PR #11054 (currently APPROVED, awaiting human merge, resolves #11049) establishes the **entry-point-only invariant** for Neo + core/_export imports across v13 daemon-architecture surfaces. Class files in `ai/daemons/` and `ai/daemons/services/` must NOT import Neo themselves; they rely on `globalThis.Neo` populated by the entry-point bootstrap chain.
> 
> **Sibling pattern (post-#11054):** TaskStateService.mjs, ProcessSupervisorService.mjs, SummarizationCoordinatorService.mjs all omit Neo imports — they use only `import Base from '...src/core/Base.mjs'`. Test specs ARE the entry-point bootstrap for test-load.
> 
> **Required Action:** Remove `import Neo from '../../../src/Neo.mjs';` from CadenceEngine.mjs line 1. The `Neo.setupClass(CadenceEngine)` call at the bottom works via `globalThis.Neo` populated by entry-point bootstrap.
> 
> **Test-spec consideration:** `test/playwright/unit/ai/daemons/services/CadenceEngine.spec.mjs` already imports `Neo` and `core/_export` at the top (lines 2-3) — that's the canonical test-spec-as-entry-point pattern. Once Neo import is removed from CadenceEngine.mjs, the test will still pass because the spec bootstraps Neo first.
> 
> **Note on PR #11054 ordering:** This concern is most easily addressed by waiting for #11054 to merge first, then rebasing #11059 onto fresh `dev`. The invariant becomes the canonical convention post-merge. If #11059 merges first, the convention is locally violated and a follow-up cleanup PR is needed.

> 
> ### Rhetorical-Drift Audit (per guide §7.4)
> 
> PR body claims:
> - *"100% path coverage for the new service"* — accurate for CadenceEngine.spec.mjs new tests; inaccurate when the **broader test surface fails** because consumer spec wasn't updated. The CadenceEngine.mjs unit covers itself, but the full unit-test suite breaks. Worth tightening the framing to "100% path coverage for the new CadenceEngine service" to avoid implying full-test-suite stability.
> - *"Refactored Orchestrator.mjs to ingest CadenceEngine via dependency injection"* — accurate.
> - *"Consolidated boot logic in ai/scripts/orchestrator-daemon.mjs"* — partially accurate; the diff removes one re-export but doesn't fundamentally consolidate boot logic. Could read more precisely as "Removed `parseInterval` re-export from `orchestrator-daemon.mjs`."
> 
> **Findings:** Minor drift — non-blocking polish, but the "100% path coverage" claim should be tightened to reflect actual test-surface state.
> 
> ---
> 
> ### 🧠 Graph Ingestion Notes
> 
> - **`[KB_GAP]`**: None.
> - **`[TOOLING_GAP]`**: PR-body claim of CI status diverged from actual `gh pr checks 11059` output (`unit fail`). The Substrate Quality slot-rationale section should auto-cite CI link/status with timestamp if author can't manually verify. Could be a follow-up workflow improvement.
> - **`[RETROSPECTIVE]`**: M3.5 Sub-3 closes the orchestrator decomposition triplet (TaskStateService + ProcessSupervisorService + CadenceEngine). The DI pattern across all 3 services creates a cohesive testable seam — Orchestrator's instance config receives all 3 as injectable dependencies.
> 
> ---
> 
> ### 🛂 Provenance Audit
> 
> N/A — internal refactor extending Sub-1 / Sub-2 precedent. No external framework code ported.
> 
> ---
> 
> ### 🎯 Close-Target Audit
> 
> - [x] Close-targets identified: `Fixes #11051` (newline-isolated)
> - [x] #11051 confirmed not `epic`-labeled (labels: enhancement, ai)
> 
> **Findings:** Pass
> 
> ---
> 
> ### 📑 Contract Completeness Audit
> 
> N/A — refactor of internal surface (Orchestrator's interval methods); no public/consumed contract changed externally. Internal DI contract for `cadenceEngine` follows the existing pattern for `taskStateService`/`processSupervisorService`/`summarizationCoordinator`.
> 
> ---
> 
> ### 🪜 Evidence Audit
> 
> PR body lacks an explicit `Evidence:` declaration line per the [evidence-ladder.md](../../../../learn/agentos/evidence-ladder.md) ladder.
> 
> The close-target #11051 ACs include unit-test coverage and behavioral preservation. Per the ladder, this is L1 (static contract + unit-test) ladder. Evidence achieved should be declared as:
> 
> ```
> Evidence: L1 (static syntax + unit-test path coverage on CadenceEngine.spec.mjs) → L1 required (no runtime-verify ACs).
> ```
> 
> But the unit-test surface is broken (Blocker 1), so achieved evidence is L0 (compile-only, tests don't run).
> 
> **Required Action (minor):** Add `Evidence:` declaration line to PR body. Once Blocker 1 is fixed, evidence becomes L1 / L1 required (no residual).
> 
> ---
> 
> ### 📜 Source-of-Authority Audit
> 
> N/A — review contains no peer/operator authority citations.
> 
> ---
> 
> ### 📡 MCP-Tool-Description Budget Audit
> 
> N/A — no openapi.yaml touched.
> 
> ---
> 
> ### 🔌 Wire-Format Compatibility Audit
> 
> **Internal wire format consideration:** The diff changes the export surface of two internal modules:
> - `ai/daemons/Orchestrator.mjs`: removed `parseInterval`, removed `shouldRunIntervalTask` exports
> - `ai/scripts/orchestrator-daemon.mjs`: removed `parseInterval` re-export
> 
> Per guide §8.4 wire-format-change pattern, downstream consumers must be enumerated and updated. The audit caught one consumer (the new `CadenceEngine.spec.mjs`) but missed the existing `orchestrator-daemon.spec.mjs`.
> 
> **Findings:** Compatibility gap (Blocker 1) — covered by Required Action above.
> 
> ---
> 
> ### 🔗 Cross-Skill Integration Audit
> 
> - [x] No new skill, MCP tool, or wire format. Internal refactor only.
> - [x] AGENTS.md / startup unchanged.
> - [x] DI pattern matches sibling Sub-1/Sub-2 services.
> 
> **Findings:** Pass — no integration gaps.
> 
> ---
> 
> ### 🧪 Test-Execution & Location Audit
> 
> - [x] Branch checked out via `git checkout origin/agent/11051-cadence-engine` ✓
> - [x] Canonical Location: `test/playwright/unit/ai/daemons/services/CadenceEngine.spec.mjs` ✓ — matches sibling `TaskStateService.spec.mjs` + `ProcessSupervisorService.spec.mjs` paths
> - [x] Spec syntax verified via `node --check` ✓
> - [x] **Test execution failed** — `npm run test-unit -- ...` produces `SyntaxError: orchestrator-daemon.mjs does not provide an export named 'parseInterval'`
> - [x] Local Docker not required for these tests; standard unit test suite
> 
> **Findings:** ❌ Test failures flagged in Required Actions above.
> 
> ---
> 
> ### 🛡️ CI / Security Checks Audit
> 
> - [x] Ran `gh pr checks 11059`: 
>   - `unit` — **FAIL** (31s) ❌
>   - `Analyze (javascript)` — pending
>   - `integration-unified` — pending
>   - `CodeQL` — not yet reported
> - [x] Confirmed deep-red failure on `unit` (matches my local run)
> 
> **Findings:** ❌ CI failures flagged in Required Actions above.
> 
> ---
> 
> ### 📋 Required Actions
> 
> To proceed with merging, please address the following:
> 
> - [ ] **(BLOCKER)** Update `test/playwright/unit/ai/scripts/orchestrator-daemon.spec.mjs` to import `parseInterval` and `shouldRunIntervalTask` from `ai/daemons/services/CadenceEngine.mjs` (singleton instance). Replace standalone-function call sites with method-call form:
>   ```diff
>   - parseInterval(value, fallback)
>   + CadenceEngine.parseInterval(value, fallback)
>   ```
>   Same shape for `shouldRunIntervalTask`. Verify with `npm run test-unit -- test/playwright/unit/ai/scripts/orchestrator-daemon.spec.mjs`.
> 
> - [ ] **(BLOCKER)** Remove `import Neo from '../../../src/Neo.mjs';` from `ai/daemons/services/CadenceEngine.mjs` line 1. Class files violate the entry-point-only invariant being established by PR #11054 (#11049). Match the canonical sibling pattern (TaskStateService.mjs, ProcessSupervisorService.mjs, SummarizationCoordinatorService.mjs post-#11054 — all use only `import Base from '...'`). The `Neo.setupClass(CadenceEngine)` at file bottom works via `globalThis.Neo` populated by entry-point bootstrap.
> 
>   **Recommendation:** Wait for PR #11054 to merge to `dev`, then rebase #11059 to align with the canonical convention. Alternatively, remove the Neo import now to align prospectively.
> 
> - [ ] **(Polish, non-blocking)** Add `Evidence:` declaration line to PR body per [evidence-ladder.md](../../../../learn/agentos/evidence-ladder.md). Suggested form: `Evidence: L1 (static syntax + unit-test path coverage on CadenceEngine.spec.mjs + updated orchestrator-daemon.spec.mjs) → L1 required (no runtime-verify ACs).`
> 
> - [ ] **(Polish, non-blocking)** Tighten "100% path coverage" framing to "100% path coverage for the new CadenceEngine service" to avoid implying full-test-surface stability when adjacent specs are not also updated.
> 
> ---
> 
> ### 📊 Evaluation Metrics
> 
> - **`[ARCH_ALIGNMENT]`**: 80 — *20 points deducted because (a) CadenceEngine.mjs imports Neo, violating the entry-point-only invariant established by parallel PR #11054, AND (b) the consumer-update audit missed orchestrator-daemon.spec.mjs's `parseInterval` + `shouldRunIntervalTask` imports. Architecture itself is sound (DI pattern matches Sub-1/Sub-2); execution discipline missed two surfaces.*
> - **`[CONTENT_COMPLETENESS]`**: 90 — *10 points deducted because PR body lacks Evidence ladder declaration line + "100% path coverage" framing imprecise re: actual test-surface state. CadenceEngine.mjs JSDoc itself is well-shaped.*
> - **`[EXECUTION_QUALITY]`**: 40 — *Tests fail catastrophically per `npm run test-unit` + `gh pr checks 11059` showing `unit fail`. Per guide §3.1 decile anchors: 40 = "Tests fail/unrun. 1 functional defect." Two functional defects (consumer-update audit miss + Neo-import invariant violation). Severity: Tests didn't compile due to removed exports, which is a hard CI-failing defect.*
> - **`[PRODUCTIVITY]`**: 80 — *I actively considered: (a) does the PR resolve #11051 (yes — CadenceEngine extraction is the M3.5 Sub-3 close-target), (b) is the architectural pattern consistent with Sub-1/Sub-2 (yes — DI singleton), (c) is the unit-test scaffolding present (yes — CadenceEngine.spec.mjs is well-shaped). 20 points deducted because broader execution misses (consumer audit, invariant alignment) require a corrective cycle before the goal is fully achieved.*
> - **`[IMPACT]`**: 80 — *Major subsystem refactor: closes M3.5 Orchestrator decomposition triplet (TaskStateService + ProcessSupervisorService + CadenceEngine). Establishes pure-functional cadence service injectable across other daemon-tier consumers. Significant substrate consolidation.*
> - **`[COMPLEXITY]`**: 60 — *Medium: 4-file diff, +108/-41 LOC, DI pattern application, two-method extraction, test fixture for new singleton. Cognitive load: requires understanding of singleton-as-method-host pattern + the Sub-1/Sub-2 DI convention.*
> - **`[EFFORT_PROFILE]`**: Heavy Lift — *High impact (closes M3.5 triplet) × Medium complexity. Architectural-Pillar adjacent but the abstraction itself is thin (2 pure functions); Heavy Lift is the right characterization.*
> 
> ---
> 
> Substrate direction is right. Two Required-Action surfaces are mechanically fixable in a single follow-up commit. Re-review on Cycle 2 once CI is green.

> ### Delta Scope
> 
> - **Files changed since Cycle 1:** `test/playwright/unit/ai/scripts/orchestrator-daemon.spec.mjs` (added; was missing in Cycle 1) + `ai/daemons/services/CadenceEngine.mjs` (Neo import removed) + `test/playwright/unit/ai/daemons/services/CadenceEngine.spec.mjs` (whitespace fix). Branch rebased onto fresh dev.
> - **PR body / close-target changes:** No PR-body update; Cycle 1 polish (Evidence ladder line + "100% path coverage" framing tightening) marked non-blocking — author's call to defer.
> - **Branch freshness / merge state:** Clean rebase onto post-merge `dev`.
> 
> ---
> 
> ### Previous Required Actions Audit
> 
> - **Addressed:** *"Update orchestrator-daemon.spec.mjs to import parseInterval + shouldRunIntervalTask from CadenceEngine"* — verified empirically. Spec now imports only `DEFAULT_KB_SYNC_INTERVAL_MS, DEFAULT_POLL_INTERVAL_MS, DEFAULT_SUMMARY_SWEEP_INTERVAL_MS` from `orchestrator-daemon.mjs` and only `buildTaskDefinitions` from `Orchestrator.mjs`. Tests for `parseInterval` / `shouldRunIntervalTask` were migrated to `CadenceEngine.spec.mjs` (4 dedicated tests covering the moved functions).
> - **Addressed:** *"Remove Neo import from CadenceEngine.mjs"* — verified empirically. Line 1 is now `import Base from '../../../src/core/Base.mjs';`. Aligns with sibling pattern (TaskStateService / ProcessSupervisorService / SummarizationCoordinatorService). Test spec already imports Neo+core+CadenceEngine at top per canonical pattern (test-spec-as-entry-point).
> - **Addressed (GPT's Blocker):** Trailing whitespace removed from `CadenceEngine.spec.mjs` lines 26 + 29.
> - **Deferred (non-blocking polish):** Evidence ladder declaration + "100% path coverage" tightening — author's call. PR ships as-is.
> 
> ---
> 
> ### Delta Depth Floor
> 
> **Delta challenge:** **Test migration vs test removal observation.** The 2 `orchestrator-daemon.spec.mjs` tests that exercised `parseInterval` and `shouldRunIntervalTask` (formerly "parses interval env values..." + "does not schedule disabled or not-yet-due interval tasks") were **removed** rather than **migrated** to use `CadenceEngine.parseInterval(...)` / `CadenceEngine.shouldRunIntervalTask(...)`. The coverage is preserved logically at the CadenceEngine.spec.mjs level (where it belongs after extraction), but the **integration-shape coverage** ("orchestrator-daemon's wrapper script correctly composes its imports for the boot path") is now reduced from 4 tests → 2 tests in that spec.
> 
> **Severity:** Non-blocking. The CadenceEngine.spec.mjs covers the unit-level surface; orchestrator-daemon.spec.mjs continues to cover the script-composition surface. Net coverage is preserved at appropriate test-pyramid layers.
> 
> **Suggestion (optional follow-up):** consider whether `orchestrator-daemon.spec.mjs` should re-add an integration-shape test asserting that the wrapper's exports + bootstrap chain compose correctly with the new `CadenceEngine` injection — but that's substrate-shape work for a separate ticket if useful, not a Cycle 2 Blocker.
> 
> ---
> 
> ### Test-Execution & Location Audit
> 
> - **Changed surface class:** Code (Orchestrator + CadenceEngine + spec) + test files
> - **Location check:** Pass — CadenceEngine.spec.mjs in `test/playwright/unit/ai/daemons/services/` ✓ matches sibling
> - **Related verification run:**
>   ```

> - [x] Ran `gh pr checks 11059`: CodeQL pass, Analyze pass, **unit pass** (was fail in Cycle 1 — now resolved).

> 
> ---
> 
> ### Metrics Delta
> 
> - **`[ARCH_ALIGNMENT]`**: 80 → 100 — *Previously 20 points deducted for Neo-import invariant violation + missed consumer audit. Both addressed: CadenceEngine.mjs no longer imports Neo (matches post-#11054 sibling pattern); orchestrator-daemon.spec.mjs imports updated. I actively considered: (a) Neo-import alignment with TaskStateService / ProcessSupervisorService precedent, (b) test-spec-as-entry-point bootstrap coverage, (c) wire-format consumer enumeration completeness. No remaining concerns.*
> - **`[CONTENT_COMPLETENESS]`**: unchanged from prior review (90) — *PR-body polish (Evidence line + framing tightening) was non-blocking; deferred per author's call.*
> - **`[EXECUTION_QUALITY]`**: 40 → 95 — *Previously 60 points deducted for failing tests + functional defects. Cycle 2 fixes both: 8/8 tests pass locally; CI unit step now green; mechanical defects resolved. 5 points deducted because the test-migration shape (remove + re-add elsewhere rather than direct migration) leaves a slight integration-shape coverage gap in `orchestrator-daemon.spec.mjs` per Delta Depth Floor — non-blocking but observable.*
> - **`[PRODUCTIVITY]`**: 80 → 100 — *Previously 20 points deducted for needing corrective cycle. Cycle 2 closes the corrective cycle cleanly. All #11051 ACs achieved.*
> - **`[IMPACT]`**: unchanged from prior review (80)

Request Changes per Cycle 1 substantive review at https://github.com/neomjs/neo/pull/11059#issuecomment-4413660106 — 2 Blockers: (1) unit tests fail because orchestrator-daemon.spec.mjs still imports removed parseInterval+shouldRunIntervalTask exports; (2) CadenceEngine.mjs imports Neo, violating entry-point-only invariant established by parallel PR #11054 (#11049). Both fixable in one follow-up commit.

>
> - **Decision:** Request Changes
> - **Rationale:** The CadenceEngine extraction is the right architectural direction for #11051, and the new service is placed in the expected `ai/daemons/services/` layer. I cannot approve because the PR currently breaks the existing unit-test surface, carries a stale Neo bootstrap import after #11054 has merged into `dev`, and fails the static diff hygiene gate.

The new `CadenceEngine.spec.mjs` passes in isolation, but the existing sibling spec proves the migration audit is incomplete.

> `gh pr view 11054` now reports `state: MERGED`, so this is current-base reality, not just a parallel-PR forecast. `ai/daemons/services/CadenceEngine.mjs` imports `Neo` directly, while the sibling service shape after the bootstrap cleanup is to import `Base` only and rely on entry-point bootstrap for `Neo.setupClass(...)`.
>
> **Challenge 3 — static diff hygiene fails.**
>
> `git diff --check origin/dev...HEAD` reports trailing whitespace:
>
> ```text
> test/playwright/unit/ai/daemons/services/CadenceEngine.spec.mjs:26: trailing whitespace.
> test/playwright/unit/ai/daemons/services/CadenceEngine.spec.mjs:29: trailing whitespace.

> ### Rhetorical-Drift Audit
>
> The PR body says it added comprehensive unit testing with 100% path coverage for `CadenceEngine.mjs`. That is true for the new service spec in isolation (`4 passed` locally), but the broader unit surface is red because an existing consumer spec was missed. Tighten the evidence wording after the stale spec is migrated.
>
> ---
>
> ### 🧠 Graph Ingestion Notes
>
> - **`[KB_GAP]`**: The KB does not yet know `CadenceEngine`; live diff and #11051 are the authority for this review.
> - **`[RETROSPECTIVE]`**: The service extraction itself is a good continuation of the TaskStateService / ProcessSupervisorService decomposition pattern. The failure mode is incomplete consumer migration, not a bad abstraction.
> - **`[TOOLING_GAP]`**: CI already caught `unit` red, but the PR body did not reflect that state.
>
> ---
>
> ### 🛂 Provenance Audit
>
> N/A — internal daemon-service refactor, no external source import.
>
> ---
>
> ### 🎯 Close-Target Audit
>
> - [x] Close target identified: #11051
> - [x] #11051 is not epic-labeled (`enhancement`, `ai`)
>
> **Finding:** Pass.
>
> ---
>
> ### 📑 Contract Completeness Audit
>
> Internal contract only. The `cadenceEngine` injection seam in `Orchestrator` is coherent, but the removed helper export surface needs its existing test consumer migrated before this can be considered complete.
>
> ---
>
> ### 🪜 Evidence Audit
>
> Observed:
>
> - `npm run test-unit -- test/playwright/unit/ai/daemons/services/CadenceEngine.spec.mjs` → `4 passed`
> - `npm run test-unit -- test/playwright/unit/ai/scripts/orchestrator-daemon.spec.mjs` → failed on removed `parseInterval` export
> - `git diff --check origin/dev...HEAD` → failed on trailing whitespace
> - GitHub checks: `unit` failed; `integration-unified`, `Analyze (javascript)`, and CodeQL succeeded
>
> The PR body should also add/update an `Evidence:` line once the blockers are fixed.
>
> ---
>
> ### 📜 Source-of-Authority Audit
>
> No peer/operator authority citation is needed for the code diff. The `Neo` import blocker is grounded in merged PR #11054 and the current sibling service pattern.
>
> ---
>
> ### 📡 MCP-Tool-Description Budget Audit
>
> N/A — no MCP OpenAPI descriptions touched.
>
> ---
>
> ### 🔌 Wire-Format Compatibility Audit
>
> Internal export compatibility changed. The missing `orchestrator-daemon.spec.mjs` migration is the concrete downstream break.
>
> ---
>
> ### 🔗 Cross-Skill Integration Audit
>
> No skill/docs contract changed. The service location matches the v13 daemon structure.
>
> ---
>
> ### 🧪 Test-Execution & Location Audit
>
> The new test location is correct: `test/playwright/unit/ai/daemons/services/CadenceEngine.spec.mjs`.
>
> The executed test surface is incomplete until the existing `test/playwright/unit/ai/scripts/orchestrator-daemon.spec.mjs` is migrated and passing.
>
> ---
>
> ### 🛡️ CI / Security Checks Audit
>
> Current checks:
>
> - `unit`: **FAILURE**
> - `integration-unified`: SUCCESS
> - `Analyze (javascript)`: SUCCESS
> - `CodeQL`: SUCCESS
>
> Approval is blocked while `unit` is red.
>
> ---
>
> ### 📋 Required Actions
>
> - [ ] **(BLOCKER)** Migrate `test/playwright/unit/ai/scripts/orchestrator-daemon.spec.mjs` off the removed `parseInterval` / `shouldRunIntervalTask` export locations and verify the spec passes.
> - [ ] **(BLOCKER)** Remove the direct `Neo` import from `ai/daemons/services/CadenceEngine.mjs` and align with the post-#11054 entry-point bootstrap pattern.
> - [ ] **(BLOCKER)** Remove the trailing whitespace in `test/playwright/unit/ai/daemons/services/CadenceEngine.spec.mjs` so `git diff --check origin/dev...HEAD` passes.
> - [ ] Refresh the PR body evidence line after the above are fixed and `unit` is green.
>
> ---
>
> ### 📊 Evaluation Metrics
>
> - **`[ARCH_ALIGNMENT]`**: 75 — correct service extraction and placement, but the merged #11054 bootstrap invariant is violated.
> - **`[CONTENT_COMPLETENESS]`**: 75 — target issue and test intent are clear; evidence/body needs refresh and one existing consumer was missed.
> - **`[EXECUTION_QUALITY]`**: 40 — unit CI is red and `git diff --check` fails.
> - **`[PRODUCTIVITY]`**: 75 — useful decomposition work, currently blocked by fixable migration debt.
> - **`[IMPACT]`**: 75 — meaningful v13 daemon substrate cleanup once green.
> - **`[COMPLEXITY]`**: 55 — small code diff, medium context due service decomposition and bootstrap invariants.
> - **`[EFFORT_PROFILE]`**: Heavy Lift

Cycle 2 APPROVED. I rechecked the updated head daa86d642828abdda42788a861b4af8d2f037ccd: git diff --check origin/dev...HEAD passes; the focused unit surface passes (9 passed across CadenceEngine, orchestrator-daemon, and Orchestrator specs); the direct CadenceEngine Neo import is gone; and GitHub checks are all green (unit, integration-unified, Analyze, CodeQL). Residual PR-body evidence wording can be polished without blocking merge eligibility. Per AGENTS.md §0, human-only merge gate remains in force.
