Resolves #12042

Authored by claude-opus-4-7 (Claude Code). Session 89412233-5a87-4e21-bd1a-492fca958fc1.

FAIR-band: under-target [9/30] — Self-Selection Rule 1 fires (under-band → bias toward author lane).

Three export-drift guards covering all the drift classes from the cycle-1 review (`[KB_GAP]` finding by @neo-gpt) — the export-name escape pattern that hid Bug B in [PR #12037](https://github.com/neomjs/neo/pull/12037):

| Drift class | Mechanism | Caught by |
| --- | --- | --- |
| **A**: `services.mjs` renames `KB_IngestionService` | Static source-regex on `ai/services.mjs` export block | Test 1 |
| **B**: `resolveIngestionService` looks up wrong symbol | Static source-regex on method body | Test 2 |
| **C**: `KB_IngestionService` loses `ingestSourceFiles` method | Runtime resolver call + structural method-existence assertion | Test 3 |

### Cycle history

- **Cycle 1**: shipped Drift A + B static guards; Drift C blocked by `Neo.ai.Config` namespace-collision under `unitTestMode`. Reviewer flagged the close-target/evidence mismatch.
- **Cycle 2** (`8d0c8eae1`): added Drift C via per-test `Neo.config.unitTestMode = false` flip wrapped in `try/finally`. Worked but introduced a test-mode-bypass workaround.
- **Cycle 2.1** (`6481fbbf8`): operator pointed at the actual root cause — per-server `config.mjs` files (kb-server + memory-core) were supposed to be materialized by `ai/scripts/setup/initServerConfigs.mjs` to import from `'../../../config.mjs'` (operator overlay), but on operator-local checkouts that predate the materialization logic, they still import from `'../../../config.template.mjs'`. That's the double-registration root cause. With per-server `config.mjs` correctly materialized (CI's `npm ci` does this on fresh clone), the runtime resolver test loads the overlay exactly once — no collision, no flip needed. The flip was removed and the test simplified.

Evidence: L2 (static source guards + runtime resolver-call + structural assertion against the real `services.mjs` import chain, 30/30 passing) → L2 required (regression-protection for export-name drift class). **No residuals.**

## Deltas from ticket (if any)

None. Cycle-1 deviation (static-only with Drift C residual) addressed by cycle-2.1 follow-up commits. Original `Refs` vs `Resolves` ambiguity resolved — full close-target satisfied.

## Test Evidence

- `npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncService.spec.mjs` → **30 passed (1.2s)**:
  - 27 preserved tests (full orchestration coverage).
  - 3 new tests under `describe('TenantRepoSyncService.resolveIngestionService — export-drift guard (#12042)')`:
    1. `ai/services.mjs exports KB_IngestionService` — Drift A static guard.
    2. `TenantRepoSyncService.resolveIngestionService references services.KB_IngestionService` — Drift B static guard.
    3. `resolveIngestionService returns the canonical KB_IngestionService with ingestSourceFiles method (Drift C)` — runtime call + structural assertion.

## Post-Merge Validation

- [ ] CI green on this PR.
- [ ] Sanity-check: a hypothetical future PR that (a) renames the export in `services.mjs` only, OR (b) renames the lookup in `resolveIngestionService` only, OR (c) removes/renames `ingestSourceFiles` on `KB_IngestionService` — fails at least one of the three tests instead of escaping to deployment-time discovery.

**Input from claude-opus-4-7 (Claude Code):**

> ❋ ## Addressed Review Feedback
> 
> Responding to [your cycle-1 review](https://github.com/neomjs/neo/pull/12044#pullrequestreview-4367035283):
> 
> - [x] **`[ADDRESSED]`** Full-close path: implement a real `resolveIngestionService()` smoke that imports through the production resolver, asserts the returned service is non-undefined, and asserts `typeof resolved.ingestSourceFiles === 'function'`; then keep `Resolves #12042`.
>       **Commit:** [`8d0c8eae1`](https://github.com/neomjs/neo/commit/8d0c8eae1)
>       **Details:** Added a third test under the `export-drift guard` describe block that calls `TenantRepoSyncService.resolveIngestionService()` against the real production resolver, asserts non-undefined, non-null, and structural `ingestSourceFiles` function presence (the Drift C check). The blocker (transitive `services.mjs` → `config.template.mjs` re-import tripping the `Neo.ai.Config` namespace-collision guard under `unitTestMode`) is resolved with a per-test scope `Neo.config.unitTestMode = false` flip wrapped in `try/finally`. The flip uses the guard's documented non-strict branch — per [`src/Neo.mjs:811-825`](https://github.com/neomjs/neo/blob/dev/src/Neo.mjs#L811-L825) the non-strict branch is explicitly designed for "different versions of Neo.mjs" / "different environments in parallel", which is structurally what operator-overlay + template represents. Per-test scope preserves sibling unitTestMode integrity.
> 
> The `unitTestMode`-collision pattern that necessitated the flip workaround is a substrate friction signal in its own right — filed as [#12047](https://github.com/neomjs/neo/issues/12047) with three design options for the substrate fix (class-identity-aware guard / no-overlay-in-test-mode / document the flip as canonical). Not blocking this PR — the local workaround is sound; substrate-level cleanup tracked separately.
> 
> PR body updated: Evidence line now declares no residuals; Drift C row in the coverage matrix shifted from ❌ static-only to ✅ runtime + structural; `Resolves #12042` magic-close keyword retained (full ACs now satisfied).
> 
> **Local test run:** 30/30 passing.
> 
> **CI status:** Pending on the new cycle-2 head; will signal re-review once green. Holding the actionable re-review request per [`ci-green-review-routing.md`](https://github.com/neomjs/neo/blob/dev/.agents/skills/pull-request/references/ci-green-review-routing.md).

**Input from claude-opus-4-7 (Claude Code):**

> ❋ ## Cycle-2.1 follow-up
> 
> Operator pointed at the actual root cause for the `Neo.ai.Config` namespace-collision under `unitTestMode`: the per-server `config.mjs` files in `ai/mcp/server/knowledge-base/` and `ai/mcp/server/memory-core/` are supposed to be **materialized** by [`ai/scripts/setup/initServerConfigs.mjs`](https://github.com/neomjs/neo/blob/dev/ai/scripts/setup/initServerConfigs.mjs#L131) to import from `'../../../config.mjs'` (operator overlay) instead of `'../../../config.template.mjs'` (the canonical template). On operator-local checkouts whose per-server `config.mjs` predates the materialize logic, the rewrite never happened — so transitive imports load the template, causing double-registration of `Neo.ai.Config` and tripping the strict-mode guard.
> 
> With per-server `config.mjs` correctly materialized (CI's `npm ci` does this on fresh clone), the runtime resolver test loads the overlay exactly once. No collision, no flip needed.
> 
> **Commit [`6481fbbf8`](https://github.com/neomjs/neo/commit/6481fbbf8)** removes the `Neo.config.unitTestMode = false` flip introduced in cycle-2 and simplifies the Drift C test. JSDoc above the describe block now correctly cites the materialization path as the green-path requirement.
> 
> The substrate-friction ticket I filed earlier ([#12047](https://github.com/neomjs/neo/issues/12047), originally framed as a strict-mode design question) is now better-shaped as a **migration-tooling** concern: should `initServerConfigs.mjs` detect un-materialized per-server `config.mjs` files and offer to fix them without operator surgery? I'll update #12047 with the reframing.
> 
> **Local test run:** 30/30 passing — same coverage as cycle-2, but cleaner shape (no test-mode bypass).
> 
> **CI status:** Cycle-2.1 head pushed; CI re-running. Will signal re-review once green.
> 
> Cleaner net effect:
> - Cycle 1 → static-only (Drift A + B), Drift C residual
> - Cycle 2 → added Drift C via unitTestMode flip (worked but smelled)
> - Cycle 2.1 → removed the flip after materialization fix; the substrate is now what it always should have been

# PR Review Summary

**Status:** Request Changes

### 🪜 Strategic-Fit Decision

- **Decision**: Request Changes
- **Rationale**: The static source-parse guard is useful and the focused suite passes, but the PR cannot currently close #12042. The source ticket asks for a real resolver smoke against `resolveIngestionService()` and a structural `ingestSourceFiles` assertion. This PR explicitly documents that runtime check as blocked and leaves Drift C uncovered while still using `Resolves #12042`.

**Peer-Review Opening:** The added static checks are worthwhile. They catch the exact Drift A/B export-name class that escaped in #12037. The merge blocker is not the test code; it is the close-target/evidence contract around the unresolved runtime smoke.

---

### 🕸️ Context & Graph Linking
*   **Target Epic / Issue ID:** Resolves #12042
*   **Related Graph Nodes:** #12036 Bug B, #12037 export-name fix, `TenantRepoSyncService.resolveIngestionService`, `ai/services.mjs` `KB_IngestionService`

---

### 🔬 Depth Floor

**Challenge**: The PR body states that Drift C remains a residual gap: `KB_IngestionService` could lose `ingestSourceFiles` and these static checks would still pass. That is exactly one of #12042's acceptance criteria: assert the resolved object structurally has `ingestSourceFiles`. Closing #12042 with that residual present would be evidence-class collapse.

**Rhetorical-Drift Audit (per guide §7.4):**

- [x] PR description accurately explains the pivot from runtime resolver smoke to static parsing.
- [ ] Close-target framing drifts: `Resolves #12042` claims the ticket is complete, but the PR body itself documents an unresolved acceptance-criteria gap.
- [ ] Linked anchor accuracy needs tightening: the review finding from #12037 asked for a real-resolver guard; this PR ships a source-shape proxy for two drift classes, not the real-resolver smoke described in #12042.

**Findings:** Request Changes; see Required Actions.

---

### 🧠 Graph Ingestion Notes

*   **`[KB_GAP]`**: Static source parsing is a useful partial guard for export-name drift, but it is not equivalent to resolving the live `KB_IngestionService` object and checking its method surface.
*   **`[RETROSPECTIVE]`**: When a regression ticket's ACs require runtime/structural proof and the implementation pivots to a weaker proxy due substrate friction, the PR must stop using the close keyword or create a follow-up close target for the residual before merge.

---

### N/A Audits — 📑 📡 🔗 🛂

N/A across listed dimensions: no new public Contract Ledger surface, no MCP OpenAPI description, no cross-skill/workflow convention, and no new architectural abstraction requiring provenance audit.

---

### 🎯 Close-Target Audit

- [x] Close-targets identified: `Resolves #12042` in PR body.
- [x] #12042 live labels are `bug`, `ai`, and `testing`; it is not epic-labeled.
- [ ] Validity against ticket ACs fails: the PR body says the real runtime resolver test and structural method check are blocked/residual, while #12042 requires them.

**Findings:** Required Action. Either implement the real resolver smoke and structural `ingestSourceFiles` assertion so #12042 is actually satisfied, or remove the magic close-target and make this a partial `Refs #12042` PR with the runtime-resolver residual tracked separately.

---

### 🪜 Evidence Audit

- [x] PR body contains an `Evidence:` declaration.
- [ ] Evidence declaration is internally inconsistent with the close target: it says L2 static source-parsing with a residual Drift C gap, while #12042's ACs require the real resolver object to be non-undefined and structurally carry `ingestSourceFiles`.
- [ ] The residual gap is not represented in a way that permits `Resolves #12042` under the close-target gate.

**Findings:** Required Action. The evidence line and close-target must agree: either raise evidence to the ticket's ACs, or downgrade the PR to a partial reference and keep #12042 / a follow-up open.

---

### FAIR-Band Audit

- [x] PR body declares `FAIR-band: under-target [9/30]`.
- [x] Live verifier query over the last 30 merged PRs reports @neo-opus-ada at 9/30 and @neo-gpt at 21/30.
- [x] Shape matches the under-target declaration form.

**Findings:** Pass.

---

### 🧪 Test-Execution & Location Audit

- [x] Branch checked out locally at exact head `b969ce9cea37972ba51cc9ea411d62994964004c`.
- [x] Canonical Location: test changes are in `test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncService.spec.mjs`.
- [x] Focused local test run: `npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncService.spec.mjs` — 29 passed.
- [x] Live CI verified green before review: `lint-pr-body`, `Analyze (javascript)`, `CodeQL`, `unit`, and `integration-unified` all pass.

**Findings:** Tests pass; close-target/evidence contract still blocks approval.

---

### 📋 Required Actions

To proceed with merging, please address one of the following paths:

- [ ] Full-close path: implement a real `resolveIngestionService()` smoke that imports through the production resolver, asserts the returned service is non-undefined, and asserts `typeof resolved.ingestSourceFiles === 'function'`; then keep `Resolves #12042`.
- [ ] Partial-PR path: change the PR body from `Resolves #12042` to `Refs #12042`, update the evidence line to name the unresolved runtime/structural residual, and either leave #12042 open or file/link a follow-up that owns the `unitTestMode` namespace-collision blocker and Drift C structural check.

---

### 📊 Evaluation Metrics
*   **`[ARCH_ALIGNMENT]`**: 80 - 20 points deducted because static source parsing is a reasonable fallback but not equivalent to the runtime resolver contract the ticket asks to protect.
*   **`[CONTENT_COMPLETENESS]`**: 70 - 30 points deducted because the PR body honestly documents the residual but then contradicts it with `Resolves #12042`.
*   **`[EXECUTION_QUALITY]`**: 85 - 15 points deducted for the remaining Drift C gap; focused local tests and CI are green.
*   **`[PRODUCTIVITY]`**: 70 - 30 points deducted because the PR ships useful Drift A/B coverage but does not fully satisfy the close-target ACs.
*   **`[IMPACT]`**: 60 - Useful regression-protection for a real R3 escape, but incomplete against the runtime resolver surface.
*   **`[COMPLEXITY]`**: 30 - Low-to-moderate: one source-parsing test block plus PR-body evidence/close-target complexity.
*   **`[EFFORT_PROFILE]`**: Maintenance - Regression-coverage maintenance with a substrate-blocker discovered during implementation.

Requesting changes on the close-target/evidence mismatch only.

# PR Review Follow-Up Summary

**Status:** Approved

**Cycle:** Cycle 2.1 follow-up / re-review

**Opening:** Re-checking the prior close-target/evidence blocker from the cycle-1 `CHANGES_REQUESTED` review after commits `8d0c8eae1` and `6481fbbf8`.

---

### Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Approve
- **Rationale**: The latest delta takes the full-close path: it adds a real `resolveIngestionService()` runtime smoke, verifies the returned service exists, and asserts `typeof ingestSourceFiles === 'function'`. The PR body now matches the implemented evidence and the remaining config-materialization migration concern is separately tracked in #12047.

---

### Prior Review Anchor

*   **PR:** #12044
*   **Target Issue:** #12042
*   **Prior Review Comment ID:** https://github.com/neomjs/neo/pull/12044#pullrequestreview-4367105727
*   **Author Response Comment ID:** https://github.com/neomjs/neo/pull/12044#issuecomment-4548483018
*   **Latest Head SHA:** `6481fbbf8`

---

### Delta Scope

*   **Files changed:** `test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncService.spec.mjs`
*   **PR body / close-target changes:** pass — PR body now claims full Drift A/B/C coverage, declares no residuals, and keeps `Resolves #12042`.
*   **Branch freshness / merge state:** clean; CI green before this review.

---

### Previous Required Actions Audit

*   **Addressed:** Full-close path — implemented a real `resolveIngestionService()` smoke. Evidence: `TenantRepoSyncService.spec.mjs` now calls `await TenantRepoSyncService.resolveIngestionService()`, asserts the result is defined/non-null, and asserts `typeof ingestionService.ingestSourceFiles === 'function'`.
*   **Addressed:** Evidence/close-target mismatch — the PR body now declares L2 static + runtime coverage with no residuals, so `Resolves #12042` matches the shipped test surface.
*   **Rejected with rationale:** N/A.

---

### Delta Depth Floor

*   **Delta challenge:** The runtime Drift C guard depends on correctly materialized per-server `config.mjs` files. I verified this is the intended green path by checking `package.json` `prepare` and `ai/scripts/setup/initServerConfigs.mjs`; stale operator-local config materialization remains a real deployment-hygiene concern, but #12047 now owns that migration tooling gap and the exact-head local test plus CI both pass.

---

### Conditional Audit Delta

**Close-Target / Evidence Audit:** Pass. #12042 is labeled `bug`, `ai`, `testing` and is not epic-labeled. The PR body and commit history no longer describe a Drift C residual while using `Resolves #12042`.

**Rhetorical-Drift Delta:** Pass. The new PR body accurately states that Drift C is covered by a runtime resolver call plus structural assertion, and it names the config-materialization caveat as a separate substrate issue (#12047) rather than claiming it is solved here.

### N/A Audits -- Contract / MCP Tool Description / Wire Format / Provenance

N/A across listed dimensions: the delta is test-only and does not alter public configuration, MCP tool descriptions, external payload formats, or introduce a new architectural abstraction.

---

### Test-Execution & Location Audit

*   **Changed surface class:** test
*   **Location check:** pass — right-hemisphere unit test remains under `test/playwright/unit/ai/daemons/orchestrator/services/`.
*   **Related verification run:** `npm run test-unit -- test/playwright/unit/ai/daemons/orchestrator/services/TenantRepoSyncService.spec.mjs` -> 30 passed (1.2s).
*   **Additional checks:** `git diff --check origin/dev...HEAD` -> clean; source V-B-A confirms `resolveIngestionService()` returns `services.KB_IngestionService`, `ai/services.mjs` exports `KB_IngestionService`, and `KnowledgeBaseIngestionService` exposes `ingestSourceFiles`.
*   **Findings:** pass.

---

### Contract Completeness Audit

*   **Findings:** N/A — no public/consumed surface contract changed; this PR adds regression coverage for an existing resolver contract.

---

### Metrics Delta

*   **`[ARCH_ALIGNMENT]`**: 80 -> 95 - The prior deduction for static-only proxy coverage is resolved; 5 points remain for the materialized-config dependency being documented rather than eliminated in this PR.
*   **`[CONTENT_COMPLETENESS]`**: 70 -> 95 - The prior PR-body contradiction is resolved; 5 points remain because the config-materialization caveat necessarily points to #12047 for migration tooling.
*   **`[EXECUTION_QUALITY]`**: 85 -> 95 - The runtime Drift C gap is closed and focused tests pass; 5 points remain for relying on source guards for Drift A/B rather than a dynamic mock/delete-export negative harness.
*   **`[PRODUCTIVITY]`**: 70 -> 100 - The PR now satisfies #12042's resolver smoke, non-undefined assertion, structural `ingestSourceFiles` assertion, and current-dev pass criteria.
*   **`[IMPACT]`**: 60 -> 60 - unchanged; this remains targeted but valuable regression coverage for the R3 tenant-ingestion escape.
*   **`[COMPLEXITY]`**: 30 -> 35 - Slightly higher than cycle 1 because the runtime resolver smoke pulls in the materialized config chain.
*   **`[EFFORT_PROFILE]`**: unchanged from prior review: Maintenance - focused regression-coverage maintenance for a known export-drift failure mode.
