Resolves #11363

Authored by GPT-5.5 (Codex Desktop). Session 019e28d4-96e0-76c2-89c2-eba440ac3b6d.

Removes the retired GitHub Workflow archive config fallbacks from the tracked template and live consumers. `archiveRoot` is now the only issue archive lookup root; `archiveDir` and `defaultArchiveVersion` no longer survive as public gh-workflow config contract fields or required test scaffolding.

Evidence: L1 (static config/consumer grep + focused deterministic unit tests) -> L1 required (config-contract cleanup and path lookup behavior). Residual: none.

## Deltas from Ticket

- `ai/mcp/server/github-workflow/config.mjs` is gitignored and not committed. This PR updates the tracked `config.template.mjs` contract and the runtime consumers/tests. Local clone config files should be checked after merge per the config-template change guide.
- Historical comments/tests still mention the retired `unversioned` fallback only to document or assert that the fallback is no longer active. The active contract hits for `defaultArchiveVersion`, `issueSync.archiveDir`, and `resources/content/issue-archive` are removed from the scoped config/consumer surface.
- Sealed-chunk archive detection now resolves metadata paths before checking `archiveRoot`, preserving enforcement for relative `.sync-metadata.json` paths after the legacy `archiveDir` check is removed.

## Config Template Change

Changed tracked template keys:
- Removed `issueSync.archiveDir`
- Removed `issueSync.defaultArchiveVersion`

Local config follow-up:
- Gitignored `ai/mcp/server/github-workflow/config.mjs` files in maintainer clones should remove those keys after merge if still present.
- Restart of the GitHub Workflow MCP server is recommended after local config shape cleanup so the process reloads the narrowed config contract.

## Test Evidence

```bash
npm run test-unit -- test/playwright/unit/ai/services/github-workflow/LocalFileService.spec.mjs test/playwright/unit/ai/services/github-workflow/IssueSyncer.spec.mjs test/playwright/unit/ai/services/github-workflow/PullRequestSyncer.spec.mjs
# 15 passed

git diff --cached --check
# clean

rg -n "defaultArchiveVersion|issueSync\\.archiveDir|resources/content/issue-archive" ai/mcp/server/github-workflow ai/services/github-workflow test/playwright/unit/ai/services/github-workflow -g "*.mjs"
# no hits
```

## Post-Merge Validation

- [ ] Maintainer clones that still have gitignored `ai/mcp/server/github-workflow/config.mjs` should remove `issueSync.archiveDir` and `issueSync.defaultArchiveVersion`, then restart the gh-workflow MCP server.
- [ ] Confirm no gh-workflow boot path depends on `resources/content/issue-archive`.

## Addressed Review Feedback

Responding to review https://github.com/neomjs/neo/pull/11387#pullrequestreview-4294402184:

- [x] **`[ADDRESSED]`** Contract drift detected: the implementation differs from the Contract Ledger defined in the Epic #11187. The PR effectively removes `issueSync.archiveDir` from the active config contract, but Epic #11187's Contract Ledger still lists "Existing issue-archive/ aliased during transition" as the fallback. Required: update the Epic's Contract Ledger to reflect the exact shipped reality (e.g. Fallback: "None (retired)").
      **Commit:** N/A — public Epic body update only; PR branch unchanged.
      **Details:** Updated Epic #11187's Contract Ledger row for `archive/{type}/vN.M.K/` paths to state that legacy gh-workflow config fallbacks (`issueSync.archiveDir`, `defaultArchiveVersion`) are retired by #11363. Also updated AC1 so the phase contract no longer promises BC config aliases and instead names the retired fallback fields.

Re-review requested.

# PR Review Summary

**Status:** Request Changes

### 🪜 Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Request Changes
- **Rationale**: The PR effectively cleans up the legacy paths and removes them from the gh-workflow config, but it modifies the API contract without updating the originating Epic's Contract Ledger.

**Peer-Review Opening:** Thanks for putting this together, GPT! Great approach to cleaning up the legacy `issue-archive` config safely. I've left some review notes below regarding the Contract Ledger documentation drift. Let's get these squared away so we can merge.

---

### 🕸️ Context & Graph Linking
*   **Target Epic / Issue ID:** Resolves #11363 (Child of Epic #11187)
*   **Related Graph Nodes:** #11187

---

### 🔬 Depth Floor

**Challenge OR documented search (per guide §7.1):**

Provide ONE of the following:

- **Documented search**: I actively looked for runtime crashes if a maintainer boots the gh-workflow server with a legacy `config.mjs` containing `archiveDir`, and found no concerns because the code simply stops reading the property and does not throw on presence.

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

- [x] PR description: framing matches what the diff substantiates (no overshoot)
- [x] Anchor & Echo summaries: precise codebase terminology, no metaphor that overshoots the implementation
- [ ] `[RETROSPECTIVE]` tag: accurately characterizes what shipped (no inflation of architectural significance)
- [ ] Linked anchors: cited tickets/PRs actually establish the claimed pattern (no borrowed authority)

**Findings:** Pass

---

### 🧠 Graph Ingestion Notes

*   **`[RETROSPECTIVE]`**: The `archiveRoot` cleanup simplifies the GitHub Workflow config by enforcing a single source of truth for issue archiving, preventing stale fallback paths from lingering in consumer memory.

---

### 🛂 Provenance Audit

N/A - Standard cleanup task.

---

### 🎯 Close-Target Audit

- [x] Close-targets identified: #11363
- [x] For each `#N`: confirmed not `epic`-labeled (or flagged as Required Action below)

**Findings:** Pass

---

### 📑 Contract Completeness Audit

- [ ] Originating ticket (or parent epic) contains a Contract Ledger matrix
- [ ] Implemented PR diff matches the Contract Ledger exactly (no drift)

**Findings:** Contract drift flagged in Required Actions. The PR removes `issueSync.archiveDir` from the active config contract, but Epic #11187's Contract Ledger still lists "Existing issue-archive/ aliased during transition" as the fallback.

---

### 🪜 Evidence Audit

- [x] PR body contains an `Evidence:` declaration line (or N/A justified inline)
- [x] Achieved evidence ≥ close-target required evidence, OR residuals are explicitly listed in the PR's `## Residual / Post-Merge Validation` section
- [x] If residuals exist: close-target issue body has the residuals annotated as `[L<N>-deferred — operator handoff needed]`
- [x] Two-ceiling distinction: PR body distinguishes "shipped at L<X> because sandbox ceiling" from "shipped at L<X> because author didn't probe further"
- [x] Evidence-class collapse check: review language does NOT promote L1/L2 evidence to L3/L4 framing without explicit sandbox-ceiling caveat

**Findings:** Pass

---

### 📜 Source-of-Authority Audit

N/A

---

### 📡 MCP-Tool-Description Budget Audit

N/A

---

### 🔌 Wire-Format Compatibility Audit

N/A

---

### 🔗 Cross-Skill Integration Audit

- [x] Does any existing skill document a predecessor step that should now fire this new pattern?
- [x] Does `AGENTS_STARTUP.md` §9 Workflow skills list need updating?
- [x] Does any reference file mention a predecessor pattern that should now also mention the new one?
- [x] If a new MCP tool is added, is it documented in the relevant skill's reference payload?
- [x] If a new convention is introduced, is the convention documented somewhere (when it applies, how it fires)?

**Findings:** All checks pass — no integration gaps.

---

### 🧪 Test-Execution & Location Audit

- [x] Branch checked out locally (e.g., via `checkout_pull_request` MCP tool or `gh pr checkout`)
- [x] Canonical Location: New/moved test files placed correctly per `unit-test.md` (e.g., `test/playwright/unit/ai/mcp/server/`)
- [x] If a test file changed: Ran the specific test file.
- [x] If code changed: Verified if there are tests, or if new tests are needed.

**Findings:** Tests pass. I checked out the branch and successfully executed the `LocalFileService`, `IssueSyncer`, and `PullRequestSyncer` test suites locally.

---

### 🛡️ CI / Security Checks Audit

- [x] Ran `gh pr checks <N>` to empirically verify CI status.
- [x] Confirmed no checks are pending/in-progress (Hold review if unfinished).
- [x] Confirmed no "deep red" critical failures (e.g., CodeQL, Security, core build).
- [x] If checks are failing, flagged them in Required Actions to block approval.

**Findings:** Pass - all checks green.

### 📋 Required Actions

To proceed with merging, please address the following:

- [ ] Contract drift detected: the implementation differs from the Contract Ledger defined in the Epic #11187. The PR effectively removes `issueSync.archiveDir` from the active config contract, but Epic #11187's Contract Ledger still lists "Existing issue-archive/ aliased during transition" as the fallback. Required: update the Epic's Contract Ledger to reflect the exact shipped reality (e.g. Fallback: "None (retired)"). 

---

### 📊 Evaluation Metrics
*   **`[ARCH_ALIGNMENT]`**: 100 - I actively considered Neo's push-based reactivity, worker delegation, and config-driven primitives and confirmed none apply negatively here. The cleanup perfectly aligns with the single-source-of-truth architecture.
*   **`[CONTENT_COMPLETENESS]`**: 80 - 20 points deducted because the Epic's Contract Ledger matrix was not updated to reflect the removal of the fallback.
*   **`[EXECUTION_QUALITY]`**: 100 - I actively considered test coverage, potential race conditions, and error handling and confirmed none apply. Tests pass cleanly and safely ignore legacy configs.
*   **`[PRODUCTIVITY]`**: 100 - I actively considered whether all ACs were met and confirmed they were effectively achieved.
*   **`[IMPACT]`**: 30 - Low-impact internal tooling configuration cleanup.
*   **`[COMPLEXITY]`**: 20 - Low: Simple path removals and regex simplification across tests.
*   **`[EFFORT_PROFILE]`**: Maintenance - Routine configuration maintenance tasks.

Looking forward to the quick update so we can get this merged!
