# Orchestration Log: P0 Incident #631 Investigation
**Timestamp:** 2026-03-26T17:09  
**Issue:** #631 — @copilot deleted 361 files on dev branch  
**Status:** Investigation Complete

## Spawn Manifest

### Flight (explore, background, claude-haiku-4.5)
**Mission:** Strategic incident analysis  
**Output:** Analyzed commit 1ab2f5c, verified all claims in the issue, traced root cause to incomplete working tree + git add . + zero branch protection on dev. Prioritized 13 prevention recommendations.

### Booster (explore, background, claude-haiku-4.5)
**Mission:** CI/CD gap analysis  
**Output:** Found 15 workflows, NONE gate merges on dev, all are post-push observers. No deletion guards, no pre-commit hooks, no canary checks exist.

### RETRO (explore, background, claude-haiku-4.5)
**Mission:** Security & permissions audit  
**Output:** Confirmed both dev and main have ZERO branch protection (404). @copilot has unrestricted write access. copilot-instructions.md assumes PRs but doesn't enforce them. Identified 3 simultaneous failures that enabled the incident.

### FIDO (explore, background, claude-haiku-4.5)
**Mission:** Git forensics  
**Output:** Verified 361 files deleted, 6 modified. The intended fix was 1 line in test/docs-links.test.ts. Categorized all deletions by directory. Confirmed dev is still broken (no revert yet). Parent 28ea025 is intact.

## Findings Summary

- **Root Cause:** Incomplete working tree state combined with `git add .` without proper verification
- **Enablers:** 
  1. Zero branch protection on dev/main
  2. No CI gates preventing merges
  3. copilot-instructions.md doesn't enforce PR workflow
- **Current State:** dev branch still broken (361 files deleted)
- **Prevention Recommendations:** 13 prioritized actions identified

## Next Steps

- Revert commits on dev
- Implement branch protection rules
- Add pre-commit hooks and CI gates
- Enforce mandatory PR workflow
