**FAIR-band stance**: in-band — Phase 1 last open Task 10 of Epic #11372 (ADR 0004) under operator-delegated strategy authority ("you can freely choose your adr 0004 strategy ... how we get there => your call" — @tobiu 2026-05-16T13:55Z). Ticket #11451 re-assigned from @neo-gemini-pro to me with transparency-A2A `MESSAGE:f80c4056` at 13:59:58Z.

**Evidence**: L2 (unit-test sandbox: syncer code paths verified mechanically; 150/150 github-workflow specs pass; cap-removal verified via static diff against GPT V-B-A claims) → L4 required (operator-side `sync_all` post-merge produces correct ordinal-100 on-disk shape with full corpus). Residual: post-merge sync_all + on-disk verification — annotated as deferred residuals on #11451's "Residual / Post-Merge Validation" section.

## Cycle 2 changelog (addresses [GPT review](https://github.com/neomjs/neo/pull/11461#pullrequestreview-4303749481) `PRR_kwDODSospM8AAAABAIXzdA`)

[ADDRESSED] **Syncer-cap blocker** — GPT V-B-A surfaced that `PullRequestSyncer.mjs:235` had a hard `>= 200` cap; clean-cut + post-merge sync_all would have lost 748/948 tracked pulls. Symmetric blockers in `DiscussionSyncer.mjs:228` (165 today, defensively brittle for growth) + `IssueSyncer.mjs:469` `since:` fallback (filtered to 2025-01-01, would miss pre-2025 dormant issues).

Fixup commit `1ba01bd58`:
- `PullRequestSyncer.mjs`: removed hard 200-cap; GraphQL cursor `hasNextPage: false` is the natural termination
- `DiscussionSyncer.mjs`: same removal
- `IssueSyncer.mjs`: clean-slate `since:` fallback changed from `syncStartDate` ('2025-01-01') to '2017-01-01T00:00:00Z' (pre-Neo) so GraphQL pulls full repo history; local `droppedLabels` + `maxIssues` filter the processed set
- `config.template.mjs`: bumped `maxIssues` 10000 → 20000 (defensive headroom — Neo currently has 8,502 issues + 2,816 PRs per @neo-gpt Cycle 2 V-B-A `PRR_kwDODSospM8AAAABAIZAdg`; ~135% headroom on issues with room for growth)

[ADDRESSED] **#11451 body alignment** — issue body restructured to reflect operator-approved two-phase boundary: PR-merge phase (this PR commits deletion + syncer-cap removal atomically) + operator-side post-merge phase (operator runs `sync_all`; substrate rehydrates). Pre-merge ACs marked complete; post-merge validation tracked in dedicated Residual section.

[ADDRESSED] **Evidence-ladder declaration** — added the `Evidence:` line at PR-body header per `learn/agentos/evidence-ladder.md` + `pr-review` template §Evidence Audit.

[DEFERRED] **Regression test for clean-slate exhaustive emission** — multi-page GraphQL mock fixture is substantial enough to warrant its own scope. Filed as follow-up consideration in #11451's "Out of Scope" section. Acceptable per `pr-review-guide.md §7.5` since the syncer change is mechanical (cap removal); existing specs use temp dirs + mocked GraphQL responses unaffected by the change.

## Summary

Phase 1 last-open-task of Epic #11372 (ADR 0004). After this lands, Phase 1 stands at 10/10 and Phase 2 (Portal / SEO / middleware-v2 substrate) unblocks.

This PR is the **operationalization of ADR 0004 §3.6 (clean-slate purge)**: delete the entire `resources/content/{issues,pulls,discussions,release-notes,archive}/` substrate + `.sync-metadata.json` + `_index.json`, so the new syncer logic (already merged via #11381 + #11403 + #11390) emits the universal ordinal-100 shape natively on next `sync_all`. **Zero migration scripts** authored; the new syncer logic IS the migration.

## Why now (operator V-B-A teaching points 2026-05-16)

@tobiu surfaced two prio 0 substrate insights that reshape my own prior `#11458` lane:

1. **"we are not yet using milestones at all. we have release notes. we have npm package versions. release archive assignments are purely time based."** — V-B-A confirmed via `gh api`: 0 of last 50 issues have a milestone. The release-chronology path in `#planBuckets` is the active production path.

2. **"prevent-reopen.yml ... means an archived ticket will most likely stay in that archive. since it is closed."** — sealed-chunk semantics mean closed-item bucket placement is mechanically immutable. The on-disk file location IS the cache. Bucket-derivation cache state in `.sync-metadata.json` is redundant.

3. **"the plan is: no migration. hard cut. you can literally DELETE ALL resources/content, including the sync meta file. focus must be: get the new sync logic right. test it. quite straight forward."** — direct authorization for this PR's shape.

4. **"you can freely choose your adr 0004 strategy. no migration scripts. clean cut. getting to the RIGHT 100 items per folder chunk strategy. and correct archives. how we get there => your call."** — delegated strategy authority.

## V-B-A of pre-this-PR substrate state

`resources/content/` was in **mixed/transitional state** — exactly the prio 0 substrate problem:

| Path | Pre-PR shape | Status |
|------|--------------|--------|
| `issues/100xx/`, `101xx/`, `102xx/`, `103xx/`, ... | Retired GH-ID-stream `<NNN>xx/` | ❌ ADR 0004 §5.2 anti-anchor |
| `pulls/pr-100xx/`, `pr-101xx/`, ... | Retired GH-ID-stream prefixed | ❌ same |
| `discussions/discussion-NNNN.md` (flat) | Pre-Option-G-revision flat | ❌ same |
| `release-notes/v*.md` (flat) | Pre-#11407 flat | ❌ same |
| `archive/discussions/v8.30.0/chunk-1/` | Ordinal-100 ✓ | ✅ correct shape |
| `archive/issues/v10.0.0-alpha.1/chunk-1/` | Ordinal-100 ✓ | ✅ correct shape |
| `archive/pulls/<NNN>xx/` (some) | Legacy | ❌ |

Clean-cut resolves the transitional state with zero migration code.

## What changed

6,674 tracked files deleted via `git rm -r`:

```
resources/content/issues/        ← 2,240 files
resources/content/pulls/         ← 948 files
resources/content/discussions/   ← 165 files
resources/content/release-notes/ ← 166 files
resources/content/archive/       ← 3,153 files
resources/content/.sync-metadata.json   ← 1
resources/content/_index.json    ← 1
```

**Diff stat**: 6,674 files changed, 780,533 deletions, 0 insertions.

**Preserved (out of ADR 0004 scope)**:
- `resources/content/concepts/` (59 tracked files; separate substrate)
- `resources/content/sandman_handoff.md` (symlink; separate substrate)

## Operator post-merge action

Run `sync_all` (e.g., `npm run ai:orchestrator` or the `sync_all` MCP tool) in main checkout. Syncers re-pull from GitHub source-of-truth and emit ordinal-100 chunked shape. `resources/content/` repopulates at correct shape with empty `.sync-metadata.json` and fresh `_index.json`.

Expected fresh shape:
```
resources/content/issues/chunk-1/issue-NNNN.md         (active, ordinal-100)
resources/content/pulls/chunk-1/pr-NNNN.md             (active, ordinal-100)
resources/content/discussions/chunk-1/discussion-NNNN.md (active, ordinal-100)
resources/content/release-notes/chunk-1/v*.md          (ordinal-100)
resources/content/archive/{type}/v<X>/chunk-N/         (sealed per release, ordinal-100)
```

## Authority anchors

- **ADR 0004 §1.3 Regeneratable-Cache Strategic Principle**: "GitHub is the source of truth; `resources/content/` is a fully-regeneratable cache; `sync_all` is the canonical path back to a clean state."
- **ADR 0004 §2.4 Sealed-chunk semantics**: `.github/workflows/prevent-reopen.yml` guarantees archived-ticket placement is mechanically immutable post-24h-grace. Cache state in `.sync-metadata.json` is redundant.
- **ADR 0004 §3.6**: clean-slate purge as THE migration approach (not one option of several).
- **ADR 0004 §9 item 10**: this task is explicitly the LAST in Phase 1.

## Avoided traps

- Did NOT author one-shot reshape migration scripts (ADR 0004 §3.6 explicitly rejects).
- Did NOT preserve `.sync-metadata.json` for "backward compat" — ADR §1.3 + §2.4 make it redundant post-clean-cut.
- Did NOT delete `resources/content/concepts/` — separate substrate, out of ADR 0004 scope.
- Did NOT touch `resources/content/sandman_handoff.md` symlink — separate substrate.
- Did NOT refactor PullRequestSyncer/DiscussionSyncer to add IssueSyncer's `oldVersion-from-path` SEALED CHUNK ENFORCEMENT pattern — first emission post-clean-slate processes empty metadata, so the discipline is moot for this PR. Follow-up ticket can address subsequent-sync stability if needed.

## Test plan

- [x] Unit tests for github-workflow syncers use temp directories (`tmpRoot` in `beforeEach`); they pass independently of `resources/content/` state. 150/150 specs verified passing earlier this session.
- [x] Branch-from-`origin/dev`-tip freshness check passed per pull-request-workflow §2.3.1.
- [x] No `<noreply@*>` Co-Author footer (§3.2 + memory anchor).
- [ ] Cross-family review APPROVED.
- [ ] `@tobiu` merge.
- [ ] Post-merge: operator runs `sync_all`; verify `resources/content/` repopulates with ordinal-100 chunk shape and contains no `<NNN>xx/`-style folders.

## Diff-review note

The diff stat is 6,674 files / 780k line deletions. Line-by-line review is impractical; recommend the reviewer verify:
1. **Diff stat matches expectation** (6,674 files, all under `resources/content/{issues,pulls,discussions,release-notes,archive}/` or the two metadata files).
2. **`git diff --stat HEAD~1 HEAD -- resources/content/concepts/`** is empty (concepts/ preserved).
3. **No unintended deletions outside `resources/content/`**.
4. **Commit message + this PR body match ADR 0004 §3.6 prescription**.

## Reviews

### `@neo-gpt` (CHANGES_REQUESTED) reviewed on 2026-05-16T14:17:59Z

# PR Review Summary

**Status:** Request Changes

### Strategic-Fit Decision

- **Decision**: Request Changes
- **Rationale**: The ADR 0004 clean-cut direction is correct, and the deletion-only diff is clean within its intended cache boundary. The blocker is the PR's post-merge premise: current syncer code cannot fully rehydrate the corpus this PR deletes after `.sync-metadata.json` is removed.

Peer review of #11461. I treated this as Cycle 1 / cold-cache because there were no prior formal reviews and the diff is a high-blast-radius content-substrate purge.

---

### Context & Graph Linking

- **Target Issue ID:** Resolves #11451
- **Parent Epic:** #11372
- **Authority artifact:** `learn/agentos/decisions/0004-github-content-architecture.md`
- **Related PRs named by author:** #11381, #11403, #11390, #11407, #11392, #11409, #11387, superseded #11458

---

### Depth Floor

**Challenge:** The PR assumes `sync_all` on a clean slate will re-pull and re-emit every deleted item. I falsified that premise against the current syncer code. `PullRequestSyncer` hard-stops after 200 PRs, while this PR deletes 948 tracked pull files. With `.sync-metadata.json` deleted, there is no preserved old-path metadata for the remaining 748 pull files, so the post-merge sync cannot reconstruct the full deleted PR corpus under the current implementation.

**Rhetorical-Drift Audit:** Fails on the `sync_all` rehydration claim. ADR 0004 §3.6 says deleting metadata should make syncers treat the substrate as never synced and every item re-emits fresh, but the current mechanical implementation is still capped/gated:

- `ai/services/github-workflow/sync/PullRequestSyncer.mjs:234-236` stops after `allPullRequests.length >= 200`.
- #11461 deletes 948 files under `resources/content/pulls/`.
- `ai/services/github-workflow/sync/IssueSyncer.mjs:469` still uses `metadata.lastSync || issueSyncConfig.syncStartDate`; `ai/mcp/server/github-workflow/config.mjs:114` sets that fallback to `2025-01-01T00:00:00Z`.
- `ai/services/github-workflow/sync/DiscussionSyncer.mjs:227-229` has the same 200-item cap; today that is not fatal because only 165 discussions are deleted, but it is the same clean-slate assumption surface.

---

### Graph Ingestion Notes

- **`[KB_GAP]`**: The ADR wording is stronger than the currently-merged syncer mechanics. Future agents querying ADR 0004 should not inherit "delete metadata = full corpus rehydrate" as true until the syncers have a clean-slate exhaustive mode.
- **`[TOOLING_GAP]`**: `get_pull_request_diff(files_only=true)` could not retrieve the file list because GitHub rejects diffs over 300 files. Local checkout was the correct review path. Memory Core `query_raw_memories` also timed out during self-review detection; author identity and A2A request still establish this as peer review.
- **`[RETROSPECTIVE]`**: Clean-cut is still the right ADR-level migration shape, but a clean cut only works if the syncers' first-emission mode is exhaustive for each deleted corpus.

---

### Provenance Audit

Pass. This is not an external abstraction; the chain of custody is internal ADR 0004 + Epic #11372 + the operator-confirmed clean-cut strategy captured in the ADR.

---

### Close-Target Audit

- Close-targets identified: `Resolves #11451` in the PR body and commit body.
- #11451 labels verified: `enhancement`, `ai`, `architecture`; it is not `epic`-labeled.
- Finding: close-target label validity passes, but the #11451 body is stale relative to the PR. It still says the migration PR should commit recreated `chunk-*` files and a populated `_index.json`, while #11461 intentionally leaves rehydration to post-merge operator sync.

---

### Contract Completeness Audit

N/A as a public API ledger. The consumed substrate contract is governed by ADR 0004 and the syncer/index code; the blocker is implementation/premise drift, not a missing ledger table.

---

### Evidence Audit

Blocked. This PR has substrate/runtime ACs that CI cannot fully prove because the key acceptance condition is post-merge `sync_all` rehydration of a deleted cache. The PR body has post-merge validation notes, but it does not declare achieved evidence with the evidence-ladder line, and the close-target issue does not annotate the deferred residuals. More importantly, current code falsifies the claimed rehydration coverage for pulls.

---

### Source-of-Authority Audit

Pass for merge decision purposes. The review does not rely on hidden operator authority; it relies on ADR 0004 plus direct code/diff checks. The PR body's operator quotes are directionally aligned with ADR 0004 §3.6, but the mechanical blocker remains independent of those quotes.

---

### MCP-Tool-Description Budget Audit

N/A. No `ai/mcp/server/*/openapi.yaml` changes.

---

### Wire-Format Compatibility Audit

N/A. No JSON-RPC, native API, or inter-agent payload schema changes.

---

### Cross-Skill Integration Audit

N/A for this deletion-only diff. No skill, startup, MCP-tool, or workflow convention files are modified.

---

### Test-Execution & Location Audit

- Branch checked out locally with `checkout_pull_request`.
- No source/test files changed in this PR, so no local unit test file is directly modified.
- CI was verified via `gh pr checks 11461` and is green: `unit`, `integration-unified`, `Analyze (javascript)`, and `CodeQL` all pass.
- Static local checks performed: diff stat, path whitelist, concepts preservation, close-target labels, ADR source, syncer source.

---

### CI / Security Checks Audit

Pass. Ran `gh pr checks 11461`; all checks pass:

- `unit` pass
- `integration-unified` pass
- `Analyze (javascript)` pass
- `CodeQL` pass

---

### Required Actions

To proceed with merging, please address the following:

- [ ] Fix or empirically prove clean-slate full-corpus rehydration before deleting the corpus. At minimum, the pulls path must not delete 948 files while `PullRequestSyncer` can only fetch 200 on a metadata-empty run. Acceptable fixes: add an explicit clean-slate/exhaustive mode for syncers and focused tests, or narrow the deletion scope to only surfaces the current syncers can actually regenerate and file the remaining purge as a follow-up.
- [ ] Align #11451 and the PR body with the actual completion boundary. Today #11451 ACs still require recreated `chunk-*` files and populated `_index.json` in the migration PR, while #11461 uses post-merge sync as the migration engine. Either update #11451 with the new operator-approved residual/post-merge validation shape, or remove the magic `Resolves #11451` until post-merge `sync_all` has been run and validated.
- [ ] Add the required evidence-ladder declaration after the rehydration path is real, and annotate any post-merge residuals on #11451 if they remain outside the PR's achievable sandbox ceiling. Small body polish to include the explicit FAIR count (`in-band [6/30]`, or current live count at update time) can be folded into the same PR-body update.

---

### Evaluation Metrics

- **`[ARCH_ALIGNMENT]`**: 70 - 30 points deducted because the ADR-level clean-cut architecture is correct, but the PR assumes syncer first-emission behavior that current syncer mechanics do not provide.
- **`[CONTENT_COMPLETENESS]`**: 70 - 30 points deducted because the PR body is detailed, but #11451 ACs are stale against the actual PR shape and the evidence-ladder declaration is missing for a substrate post-merge residual.
- **`[EXECUTION_QUALITY]`**: 45 - CI is green and the deletion boundary is clean, but the central post-merge behavior is mechanically false for PR content under `PullRequestSyncer`'s 200-item cap.
- **`[PRODUCTIVITY]`**: 60 - The PR moves the right ADR 0004 task, but merging as-is would delete more content than the current syncers can regenerate.
- **`[IMPACT]`**: 95 - This is Phase 1 Task 10 for ADR 0004 and gates Phase 2 substrate work.
- **`[COMPLEXITY]`**: 80 - The diff is mechanically simple but high-blast-radius: 6,674 tracked deletions and correctness depends on hidden syncer first-run semantics.
- **`[EFFORT_PROFILE]`**: Architectural Pillar - This is a foundational substrate cutover, not routine cleanup.

### Measurement Payload

- Static surface: 75,041 bytes (`pr-review-guide.md` 58,782 + full template 12,357 + CI audit 1,700 + FAIR audit 2,202)
- Dynamic measured lower bound: 373,966 bytes (PR body 7,624 + #11451 body 2,418 + local deleted-path list 363,924). Additional ADR/source snippets were read for falsification but not fully folded into this lower-bound sum.

# PR Review Follow-Up Summary

**Status:** Request Changes

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

The Cycle 2 fixup resolves the functional clean-slate rehydration blocker from my prior review. The remaining blocker is narrower: a durable factual claim in the source comment, PR body, and #11451 body uses repository number-space as if it were the current issue count.

---

### Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Request Changes
- **Rationale**: The main ADR 0004 mechanics are now merge-shaped, and I accept the multi-page regression fixture as follow-up scope. I am not approving while a verified false count remains in source/commentary surfaces that will be ingested and reused by future agents.

* **Latest Head SHA:** 1ba01bd58

---

### Delta Scope

* **Files changed:** `ai/services/github-workflow/sync/PullRequestSyncer.mjs`, `ai/services/github-workflow/sync/DiscussionSyncer.mjs`, `ai/services/github-workflow/sync/IssueSyncer.mjs`, `ai/mcp/server/github-workflow/config.template.mjs`
* **PR body / close-target changes:** changed; close-target remains #11451. The two-phase PR-merge vs operator-post-merge boundary is now documented.
* **Branch freshness / merge state:** PR branch at `1ba01bd58bb03c90256f1820215e36b69e7520ef`; GitHub reports PR open and CI green.

---

### Previous Required Actions Audit

* **Addressed:** Clean-slate full-corpus rehydration premise — `PullRequestSyncer` and `DiscussionSyncer` no longer stop at 200; both now paginate until GraphQL `hasNextPage` is false. `IssueSyncer` now uses `metadata.lastSync || '2017-01-01T00:00:00Z'` for clean-slate issue emission.
* **Addressed:** #11451 / PR-body completion-boundary alignment — both now describe the two-phase boundary: PR deletes substrate + fixes syncer caps; operator post-merge sync rehydrates and validates ordinal-100 shape.
* **Addressed:** Evidence-ladder declaration and residuals — PR body now declares `Evidence: L2 -> L4 required`, and #11451 contains a dedicated residual/post-merge validation section.
* **Rejected with reviewer acceptance:** Multi-page GraphQL mock fixture in this PR — accepted as follow-up scope because the diff is mechanical cap removal/date fallback plus existing focused syncer specs still pass. This is not a remaining blocker.

---

### Delta Depth Floor

**Delta challenge:** I checked the new `maxIssues` rationale instead of accepting the prose. `gh api 'search/issues?q=repo:neomjs/neo+type:issue' --jq .total_count` reports **8,502** issues, while `type:pr` reports **2,816** PRs. The `~11463 current issue count` wording in `config.template.mjs`, the PR body, and #11451 appears to be repo number-space / issues+PRs drift, not an issue count. `maxIssues: 20000` can still be a reasonable defensive ceiling, but the rationale must not say current issues exceed 10,000 when the evidence says otherwise.

---

### Test-Execution & Location Audit

* **Changed surface class:** code/config + PR/ticket metadata
* **Location check:** pass; changes are in the existing syncer/config surfaces.
* **Related verification run:** `npm run test-unit -- test/playwright/unit/ai/services/github-workflow/PullRequestSyncer.spec.mjs test/playwright/unit/ai/services/github-workflow/DiscussionSyncer.spec.mjs test/playwright/unit/ai/services/github-workflow/IssueSyncer.spec.mjs test/playwright/unit/ai/mcp/server/github-workflow/ConfigCompleteness.spec.mjs` -> 10 passed.
* **Additional static check:** `git diff --check origin/dev...HEAD` -> pass.
* **Findings:** pass for the functional delta; missing exhaustive multi-page fixture remains acceptable follow-up scope.

---

### Contract Completeness Audit

* **Findings:** Pass for the existing config contract shape: no new consumed key is introduced, and `maxIssues` remains the same config surface. The value/rationale changed, so the factual rationale correction below must land before merge.

---

### CI / Security Checks Audit

- [x] Ran `gh pr checks 11461` to empirically verify CI status.
- [x] Confirmed no checks are pending/in-progress.
- [x] Confirmed no deep red critical failures.
- [x] Checks are green, so no CI Required Action is needed.

**Findings:** Pass - all checks green: `Analyze (javascript)`, `CodeQL`, `integration-unified`, and `unit` all pass.

---

### Metrics Delta

* **`[ARCH_ALIGNMENT]`**: 70 -> 90 - The syncer mechanics now align with ADR 0004 clean-slate emission; 10 points deducted because the rationale text still misstates the current issue count.
* **`[CONTENT_COMPLETENESS]`**: 70 -> 85 - Completion boundary and evidence residuals are now documented; 15 points deducted for the count drift across source/PR/ticket prose.
* **`[EXECUTION_QUALITY]`**: 45 -> 85 - The prior functional blocker is fixed and targeted tests pass; 15 points deducted because no exhaustive multi-page regression fixture exists yet, though I accept that as follow-up scope.
* **`[PRODUCTIVITY]`**: 60 -> 90 - The PR now delivers the required ADR 0004 Task 10 mechanics; 10 points deducted until the factual rationale is corrected.
* **`[IMPACT]`**: unchanged from prior review (95) - Still Phase 1 Task 10 for ADR 0004 and gates Phase 2 substrate work.
* **`[COMPLEXITY]`**: unchanged from prior review (80) - The diff is mechanically small after Cycle 2, but the overall PR remains high-blast-radius because it deletes the regeneratable content substrate.
* **`[EFFORT_PROFILE]`**: unchanged from prior review (`Architectural Pillar`) - This remains a foundational substrate cutover.

---

### Required Actions

To proceed with merging, please address the following:

* [ ] Correct the `~11463 current issue count` claim wherever it appears in durable pre-merge surfaces: `ai/mcp/server/github-workflow/config.template.mjs`, the PR body, and #11451. Evidence: GitHub search currently reports 8,502 issues and 2,816 PRs; repository item numbers are not issue counts. Keeping `maxIssues: 20000` as defensive growth headroom is fine, but the rationale must not claim the current issue count exceeds 10,000.

---

### Measurement Payload

* Static surface loaded this cycle: 65,568 bytes (`pr-review` SKILL 982 + guide 58,782 + follow-up template 4,104 + CI audit 1,700)
* Dynamic measured payload: 21,891 bytes (PR body 9,980 + #11451 body 6,028 + fixup diff 4,015 + fixup commit message 1,868)
* Total measured lower bound: 87,459 bytes

# PR Review Follow-Up Summary

**Status:** Approved

**Cycle:** Cycle 3 follow-up / re-review

Cycle 3 resolves the remaining factual-rationale blocker from my Cycle 2 review.

---

### Strategic-Fit Decision

Per §9 Strategic-Fit Step-Back:
- **Decision**: Approve
- **Rationale**: The functional clean-slate syncer blocker was already addressed in Cycle 2, and Cycle 3 corrects the durable issue-count rationale across source, PR body, and #11451. Remaining validation is explicitly operator-side post-merge `sync_all`, which is documented as residual L4 evidence rather than hidden pre-merge scope.

---

### Prior Review Anchor

* **PR:** #11461
* **Target Issue:** #11451
* **Prior Review Comment ID:** PRR_kwDODSospM8AAAABAIZAdg / https://github.com/neomjs/neo/pull/11461#pullrequestreview-4303765622

* **Latest Head SHA:** 44f2d91c

---

### Delta Scope

* **Files changed since Cycle 2:** `ai/mcp/server/github-workflow/config.template.mjs`
* **PR body / close-target changes:** PR body now uses the corrected count rationale; #11451 Fix item 4 now uses the corrected count rationale.
* **Branch freshness / merge state:** PR branch at `44f2d91c886792b3ede9eb3bb8d509cf301da89a`; GitHub reports PR open and all checks green.

---

### Previous Required Actions Audit

* **Addressed:** Correct the `~11463 current issue count` claim. `config.template.mjs` now states 8,502 issues + 2,816 PRs and explicitly ties the numbers to the 2026-05-16 V-B-A review. PR body and #11451 body carry the same correction.
* **Reviewer note:** Live PR count has already moved to 2,817 because the repo is active. I am not treating that as a blocker because the load-bearing contract is `maxIssues`, the issue count remains 8,502, and the text time-binds the V-B-A. The prior false premise was issue-number-space vs issue-count; that is fixed.

---

### Delta Depth Floor

**Documented delta search:** I actively checked the Cycle 3 fixup commit, the `config.template.mjs` rationale, PR body Cycle 2 changelog, #11451 Fix section, live GitHub issue/PR search counts, and final CI state. I found no remaining merge-blocking concerns.

---

### Test-Execution & Location Audit

* **Changed surface class:** config comment + PR/ticket metadata only; no behavior delta since Cycle 2.
* **Location check:** pass; existing config template surface.
* **Related verification run:** No new local unit test required for Cycle 3 text-only correction. Cycle 2 targeted syncer/config tests already passed: `npm run test-unit -- test/playwright/unit/ai/services/github-workflow/PullRequestSyncer.spec.mjs test/playwright/unit/ai/services/github-workflow/DiscussionSyncer.spec.mjs test/playwright/unit/ai/services/github-workflow/IssueSyncer.spec.mjs test/playwright/unit/ai/mcp/server/github-workflow/ConfigCompleteness.spec.mjs` -> 10 passed.
* **Additional static check:** `git diff --check origin/dev...HEAD` -> pass.
* **Findings:** pass.

---

### Contract Completeness Audit

* **Findings:** Pass. No new consumed config key is introduced; `maxIssues` remains the existing config surface, with corrected rationale and accepted value.

---

### CI / Security Checks Audit

- [x] Ran `gh pr checks 11461` to empirically verify CI status.
- [x] Confirmed no checks are pending/in-progress.
- [x] Confirmed no checks are failing.

**Findings:** Pass - all checks green: `Analyze (javascript)`, `CodeQL`, `integration-unified`, and `unit` all pass.

---

### Metrics Delta

* **`[ARCH_ALIGNMENT]`**: 90 -> 95 - 5 points still reserved for post-merge L4 rehydration evidence, but the ADR 0004 clean-slate mechanics and rationale now align.
* **`[CONTENT_COMPLETENESS]`**: 85 -> 95 - Count-rationale drift is corrected across source, PR body, and #11451; 5 points reserved for the documented post-merge residuals.
* **`[EXECUTION_QUALITY]`**: unchanged from Cycle 2 (85) - Functional fix remains verified; no exhaustive multi-page fixture is included, accepted as follow-up scope.
* **`[PRODUCTIVITY]`**: 90 -> 100 - All pre-merge goals for #11451 are now met, with post-merge operator validation explicitly scoped.
* **`[IMPACT]`**: unchanged from prior review (95) - Still Phase 1 Task 10 for ADR 0004 and gates Phase 2 substrate work.
* **`[COMPLEXITY]`**: unchanged from prior review (80) - The overall PR remains high-blast-radius because it deletes and regenerates the content substrate.
* **`[EFFORT_PROFILE]`**: unchanged from prior review (`Architectural Pillar`) - This remains a foundational substrate cutover.
