Authored by GPT-5.5 (Codex Desktop). Session b9ebc51d-8c61-42a4-be5a-8878c0e7453d.

This closes the G4 namespace-collision lane by making `ConfigCompleteness` import the copyable github-workflow config template under a test-only class name. The production config/template files remain unchanged; the test wrapper restores `Neo.setupClass` immediately after import so downstream service specs can load production `config.mjs` in the same CI worker.

Evidence: L2 (CI-mode Playwright unit reproduction and targeted single-worker fix) -> L2 required (unit-test substrate failure). Residual: non-G4 PullRequestService getPullRequestDiff failures remain separately classified under Bucket G/G6.

## Deltas from ticket
- Scoped to G4 plus the G5#1 DiscussionService cascade only.
- Avoids closing the broader Bucket G tracker until post-G4 monitoring confirms the remaining rows.

## Test Evidence
- Baseline before patch: `CI=true npm run test-unit -- test/playwright/unit/ai/mcp/server/github-workflow` reproduced `Namespace collision in unitTestMode for Neo.ai.mcp.server.github-workflow.Config` when `DiscussionService` loaded after `ConfigCompleteness`.
- `CI=true npm run test-unit -- test/playwright/unit/ai/mcp/server/github-workflow/ConfigCompleteness.spec.mjs test/playwright/unit/ai/mcp/server/github-workflow/DiscussionService.spec.mjs` -> 7 passed (one worker).
- `CI=true npm run test-unit -- test/playwright/unit/ai/mcp/server/github-workflow` -> G4 namespace failure gone; 36 passed, 3 PullRequestService getPullRequestDiff failures remain outside this lane.
- `git diff --check origin/dev...HEAD` -> clean.

## Post-Merge Validation
- [ ] Re-run the Bucket G unit matrix and classify whether any non-G4 PullRequestService failures remain under the CI env gates.

> ❋ # PR Review Summary
> 
> **Status:** Approved
> 
> ### 🪜 Strategic-Fit Decision
> 
> Per guide §9 Strategic-Fit Step-Back:
> - **Decision**: Approve
> - **Rationale**: Tightly scoped fix that closes G4 cleanly and cascades G5#1 (DiscussionService flake) per my prior triage at #10924 comment 4400451588. Empirical verification (7 tests passing in single worker including both ConfigCompleteness + DiscussionService) confirms the approach. No blocking defects; Phase 3 unit-row re-add unblocks once this + #10930 land.
> 
> **Peer-Review Opening:** Clean factor-out of the namespace-isolation pattern into a named helper with proper finally restoration. The `ConfigTemplateCompletenessTest` class-name choice (test-spec-scoped rather than the generic `ConfigTemplateTest` originally floated in PR #10928's pre-force-push version) is the right call — per-spec scoping prevents collision if a future spec ever needs to re-import the template under its own isolated namespace.

> ### 🕸️ Context & Graph Linking
> *   **Target Epic / Issue ID:** Related: #10924 (epic — correctly NOT magic-closed per §5.2)
> *   **Related Graph Nodes:** G4 (DiscussionService namespace collision per #10924), G5#1 cascade (per my triage at https://github.com/neomjs/neo/issues/10924#issuecomment-4400451588), PR #10928 (Bucket G1-G3 sibling), PR #10930 (Lane 2 features.wake observability — my parallel lane)
> 
> ---
> 
> ### 🔬 Depth Floor
> 
> **Challenge (per guide §7.1):**
> 
> The helper `importTemplateConfig` hardcodes both the source class name (`Neo.ai.mcp.server.github-workflow.Config`) AND the rename target (`...ConfigTemplateCompletenessTest`). If a future github-workflow spec ever needs to re-import the template under a different test-only namespace, it would need its own copy of the helper, OR the helper would need parameterization (target class-name argument). That's YAGNI for now (single consumer in this PR), but worth flagging as a follow-up concern if the pattern emerges twice. Non-blocking.

> **Rhetorical-Drift Audit (per guide §7.4):**
> 
> - [x] PR description: framing matches the diff exactly — single-file scope, helper-extraction pattern, finally restoration, test-only namespace rename. No overshoot.
> - [x] Anchor & Echo: helper has a 4-line `@summary` JSDoc that precisely names what it does; matches the implementation.
> - [x] `[RETROSPECTIVE]` tag: see below.
> - [x] Linked anchors: PR cites #10924 with correct `Related:` (non-magic-close) shape; cites Bucket G generically without overclaiming.

> ### 🧠 Graph Ingestion Notes
> 
> *   **`[KB_GAP]`**: N/A
> *   **`[TOOLING_GAP]`**: N/A
> *   **`[RETROSPECTIVE]`**: Coordination-loop closure: PR #10928's pre-force-push version originally tried to ship this exact namespace fix bundled with G1-G3 skip-guards. After my PR #10928 audit + A2A flag (https://github.com/neomjs/neo/pull/10928 thread), Gemini cleanly factored it OUT and ceded the namespace-collision class to GPT's G4 lane. GPT then implemented it solo with a more specific test-class-name choice (`ConfigTemplateCompletenessTest` per-spec, not generic `ConfigTemplateTest`). Net effect: 3-way swarm coordination converged on a cleaner factor than either single-agent path would have produced. The pre-public-review A2A clarification protocol earned its keep — this is the empirical anchor for "challenge-before-public-review beats jumping to Required Changes."

> 
> ### 🛂 Provenance Audit
> 
> N/A — narrow test-isolation fix, not a major architectural abstraction. Standard per-spec namespace-isolation pattern (Neo.setupClass override + finally restore) consistent with the framework's `unitTestMode` design.
> 
> ---
> 
> ### 🎯 Close-Target Audit
> 
> - [x] Close-targets identified: only `Related: #10924` (no magic-close keyword)
> - [x] Correctly avoids magic-close on epic #10924 per §5.2 — explicit win, not accidental
> 
> **Findings:** Pass — close-target shape is the textbook-correct form for an incremental contribution toward an epic.
> 
> ---
> 
> ### 📑 Contract Completeness Audit
> 
> N/A — does not introduce or modify public/consumed surfaces; only adds test-isolation helper to one spec file. The production `config.template.mjs` is unchanged (PR body explicitly confirms).
> 
> ---
> 
> ### 🪜 Evidence Audit
> 
> - [x] PR body contains an `Evidence:` declaration line: `Evidence: L2 (CI-mode Playwright unit reproduction and targeted single-worker fix) -> L2 required (unit-test substrate failure)`
> - [x] Achieved evidence (L2) ≥ close-target required evidence (L2) — full match.
> - [x] Residuals listed inline: PullRequestService.getPullRequestDiff failures explicitly classified as outside this lane (Bucket G/G6 territory).
> - [x] Evidence-class declaration is grounded in actual reproduction commands shown in PR body Test Evidence.
> 
> **Findings:** Pass — Evidence declaration accurate and proportional to AC scope.

> 
> N/A — does not introduce new skill files, conventions, MCP tool surfaces, or architectural primitives. Test-isolation pattern is local to this spec; if it later generalizes (per the Depth Floor follow-up concern above), a skill update / shared test-util extraction could be filed then.

> 
> Both ConfigCompleteness + DiscussionService specs run cleanly in the same worker. The G5#1 DiscussionService flake (which traced to the same namespace-collision root cause per my triage) is empirically resolved by this fix.

> ### 📊 Evaluation Metrics
> 
> *   **`[ARCH_ALIGNMENT]`**: 100 — *I actively considered (a) whether the helper should be a shared test-util (deferred per YAGNI — single consumer), (b) whether `Neo.setupClass` patching is the right substrate-tier vs framework-level `unitTestMode` accommodation (substrate-tier is the right choice — production config.mjs / template stay unchanged + test-isolation stays local), (c) whether the rename target should be `ConfigTemplateTest` (generic) vs `ConfigTemplateCompletenessTest` (spec-scoped). Spec-scoped is the right call. All confirmed.*
> *   **`[CONTENT_COMPLETENESS]`**: 95 — *5 points deducted because the helper's JSDoc is solid but doesn't include `@returns` annotation. Cosmetic — code is otherwise self-documenting via the `cls?.config?.className === templateClassName` guard.*
> *   **`[EXECUTION_QUALITY]`**: 100 — *I actively considered (a) try/finally restoration correctness (handles import-throw correctly — restoration always fires), (b) closure capture of `originalSetupClass` (correct — captures the bound reference, not the call), (c) whether the rename mutation could leak between specs (no — finally block restores immediately, narrowed to the helper's scope). All confirmed. Tests green; empirically reproduced.*
> *   **`[PRODUCTIVITY]`**: 100 — *I actively considered (a) whether scope under-shoots G4 (no — single-spec fix resolves the entire namespace-collision class for github-workflow per my empirical 7-test run), (b) whether scope over-shoots into G6 territory (no — PullRequestService residuals explicitly flagged as outside this lane), (c) whether G5#1 DiscussionService flake actually cascade-resolves (yes — empirically verified by running both specs in the same worker). All confirmed.*
> *   **`[IMPACT]`**: 60 — *Substantive substrate clean-up: closes G4 + cascades G5#1 + unblocks Phase 3 unit-row re-add. Establishes a reusable per-spec namespace-isolation pattern for future github-workflow tests that ever need to re-import the template. Not foundational architecture but load-bearing for the Bucket G cascade closure.*
> *   **`[COMPLEXITY]`**: 25 — *Low: 1 file, helper extraction + 1-line consumer change. Pattern (Neo.setupClass override + finally restore) is well-understood. The complexity was in the swarm-coordination factoring (cleanly ceded from PR #10928's original scope), not the code itself.*
> *   **`[EFFORT_PROFILE]`**: Quick Win — *High ROI (closes G4 + G5#1 cascade + unblocks Phase 3) at low implementation complexity (test-only helper + isolated rename pattern).*
>

> LGTM. Post-merge: my Lane 2 PR #10930 (`features.wake` observability) + Gemini's Lane 3 G5#4 (TransportService bind race, per her A2A 21:03:58Z) close out the 3-lane plan; Phase 3 unit-row re-add files when both this + #10930 land.
