# Epic #11187 Phase 0B: Fail-Closed Write Guard for SyncService

**Context**
The GitHub Workflow MCP server's `GH_SyncService.runFullSync()` and the release script `publish.mjs` currently exhibit fail-open write behavior. When content synchronization or metadata reconciliation fails, these scripts proceed to automatically `git add .`, `git commit`, and `git push`, permanently cementing the corrupted state (e.g., the recent `issue-archive` path drift) into the repository.

**The Problem**
As detailed in Epic #11187 (Phase 6 Activation Strategy, comment 4450311817), before executing the massive 3,153 file data migration, we must establish a tracked fail-closed guard. Proceeding with data migration while the write-amplifier is active risks multiplying the same class of error at scale. 

**The Architectural Reality**
- `ai/mcp/server/github-workflow/src/GH_SyncService.mjs` auto-commits and pushes after metadata saves even if integrity failures occur.
- `buildScripts/release/publish.mjs` catches `GH_SyncService.runFullSync()` failures, logs them, but then still proceeds to broad `git add .`, `git commit`, and `git push`.

**The Fix**
1. Modify `GH_SyncService.runFullSync()` to implement a strict fail-closed gate: if any synchronization, metadata reconciliation, or integrity validation step fails, bypass the `pushToRepoAfterSync` path entirely.
2. Modify `buildScripts/release/publish.mjs` to abort the release process (exit with error) if `GH_SyncService.runFullSync()` throws an exception or returns a failure status.

**Acceptance Criteria**
- [ ] `publish.mjs` halts execution and does NOT commit/push if `GH_SyncService.runFullSync()` fails.
- [ ] `GH_SyncService.runFullSync()` suppresses all auto-commit and push operations when integrity/sync errors are detected.
- [ ] Verify functionality via dry-run or unit test to ensure fail-closed behavior.

**Out of Scope**
- The actual movement and migration of `issue-archive` files (which is covered by subsequent phases of Epic #11187).
