#206)

* fix: remove corrupted filename that leaked from worktree operations

* fix: add git worktrees to .gitignore (should not be committed)

* docs(retrospective): Shell script anti-pattern analysis - implementer role feedback

Add retrospective analyzing the decision to create shell scripts (Detect-CopilotFollowUpPR.ps1,
detect-copilot-followup.sh) despite memory-first architecture mandate.

Root Cause Analysis:
- Implementer code-first bias (write code → solve problem)
- Skipped Step 0 (list_memories) from SESSION-PROTOCOL.md Phase 1
- Velocity pressure: scripts faster than memory documentation
- Failed to verify architecture mandate before implementation

Decision Retrospective:
- Created scripts: Sessions 40-41 (anti-pattern)
- Refactored: Session 41 (memory-first, commit 300ce04)
- Lesson: Memory-first patterns do NOT need executable scripts

Extracted Skill (92% atomicity):
Skill-Implementation-Architecture-001: Memory-First Pattern Before Code
- For detection/decision logic, document in memory FIRST
- Agents read institutional knowledge at Step 0 (list_memories)
- No shell scripts needed for pattern matching
- Applied to: Skill-PR-Copilot-001 follow-up detection

Safety Gates Before Phase 2 Launch:
✅ Shell scripts deleted (commits removed)
✅ Memory pattern documented (Skill-PR-Copilot-001)
✅ Template updated (no script references)
⏳ Verification gates pending (orchestrator review)

Commitment: Phase 2 execution will be fully memory-first, no external scripts

* docs(retrospective): Session 40-41 coordination analysis - branch isolation failures

Comprehensive retrospective on coordination gaps that led to shared branch violation.

Five-part analysis:
1. Coordination signals missed (no upfront branch allocation, no verification gates)
2. Git protocol failure (corrupted filename leaked through)
3. Root cause analysis (session start gap → agents defaulted to convenience)
4. Extracted skill: coordination-verification-001-branch-isolation-gate (92% atomicity)
5. Phase 2 launch requirements (5 mandatory blocking gates)

Key learnings:
- Constraints must be explicit (silence = convenience defaults)
- Verification beats assumption (verify at 15 min, not discovery)
- Protocol enforcement requires gates (advisory ≠ mandatory)
- Git corruption detection needs pre-commit validation

Phase 2 launch blocked pending completion of Gates 1-4:
1. SESSION-PROTOCOL.md Phase 0 update (MANDATORY)
2. Pre-commit hook validation (REQUIRED)
3. Coordination agent briefing (REQUIRED)
4. Team-wide protocol confirmation (REQUIRED)
5. Memory-first architecture (✅ DONE)

* docs(retrospective): add comprehensive Sessions 40-41 retrospective with multi-agent synthesis and skill extraction

* chore: preserve Session 41 retrospective artifacts from cleanup

Preserved from pr-review-consolidation worktree before removal:
- 2025-12-20-session-41-follow-up-tasks.md (1 actionable: FAIL verdict test)
- 2025-12-20-session-41-pr-review-consolidation.md (PRs #94,#95,#76,#93 analysis)

Added orphaned retrospective:
- 2025-12-20-lawe-qa-sessions-40-41-analysis.md

Cleanup performed:
- Removed 2 stale worktrees (.work-pr-consolidation, ai-agents-pr147)
- Deleted 12 orphaned branches (remotes gone)
- Reduced branch count from 42 to 30
