+# Analysis: Merge Resolver Session Protocol Gap
+
+## 1. Objective and Scope
+
+**Objective**: Determine why session protocol validation often fails after merge conflict resolution and identify pre-checks needed in merge-resolver workflow.
+
+**Scope**:
+- Merge-resolver skill workflow (`.claude/skills/merge-resolver/`)
+- Session protocol validation (`.agents/SESSION-PROTOCOL.md`)
+- PR #246 as case study
+- Template sync validation workflow
+
+**Out of Scope**:
+- Fixing session logs in PR #246
+- Modifying session protocol requirements
+- Template generation logic changes
+
+## 2. Context
+
+### User Report
+
+"this check is often missed after merge conflict resolution"
+
+**Observed in**: PR #246 (`docs/ai-misses`)
+**Failed Check**: Session Protocol Validation
+**CI Run**: https://github.com/rjmurillo/ai-agents/actions/runs/20547869634/job/59021014276
+
+### Current State
+
+**Merge-Resolver Skill** (`.claude/skills/merge-resolver/`):
+- Auto-resolves template files by accepting main branch version
+- Does NOT verify session protocol compliance before pushing
+- Does NOT run template regeneration after conflict resolution
+- Does NOT validate generated files match templates
+
+**Session Protocol Requirements** (`.agents/SESSION-PROTOCOL.md`):
+- MUST create session log early
+- MUST complete protocol compliance section
+- MUST run validation before claiming completion
+- MUST commit with evidence
+
+## 3. Approach
+
+**Methodology**:
+1. Analyzed PR #246 failure logs
+2. Reviewed merge-resolver skill source code
+3. Examined auto-resolvable file patterns
+4. Traced template generation workflow
+5. Compared with session protocol requirements
+
+**Tools Used**:
+- `gh pr view 246` - PR metadata
+- `gh pr checks 246` - CI check results
+- `gh run view 20547869634 --log` - Detailed logs
+- `Read` - Source code analysis
+- Serena memory search - Historical patterns
+
+**Limitations**:
+- Cannot access full CI logs (truncated output)
+- Limited to PR #246 as single case study
+- No historical data on frequency of this pattern
+
+## 4. Data and Analysis
+
+### Evidence Gathered
+
+| Finding | Source | Confidence |
+|---------|--------|------------|
+| Template sync validation PASSED in PR #246 | `gh pr checks 246` | High |
+| Session protocol validation FAILED with 9 MUST violations | CI logs | High |
+| Merge-resolver auto-resolves templates to main | Resolve-PRConflicts.ps1 L75-104 | High |
+| No session protocol pre-check in merge-resolver | Merge-resolver SKILL.md | High |
+| Template regeneration not triggered by merge-resolver | Generate-Agents.ps1 workflow | High |
+
+### Facts (Verified)
+
+**Fact 1**: User's complaint is MISIDENTIFIED
+
+- **User perception**: "template sync check often fails"
+- **Reality**: Session Protocol Validation fails, NOT template sync validation
+- **Evidence**: PR #246 shows "Validate Generated Files: PASS" but "Aggregate Results (Session Protocol): FAIL"
+
+**Fact 2**: Merge-resolver auto-resolves templates
+
+**Pattern matched**:
+```powershell
+'templates/*',
+'templates/*/*',
+'templates/*/*/*',
+```
+
+**Result**: Templates in conflict are replaced with main branch version
+**Location**: `.claude/skills/merge-resolver/scripts/Resolve-PRConflicts.ps1` lines 93-96
+
+**Fact 3**: Template changes require regeneration
+
+**Workflow**: Template change → Run `Generate-Agents.ps1` → Commit generated files
+
+**Gap**: Merge-resolver accepts main's template but does NOT regenerate platform-specific outputs
+
+**Fact 4**: Session protocol violations in PR #246
+
+**Violations**: 9 MUST requirement failures across 3 session files:
+- `2025-12-22-session-64-guardrails-premortem.md`: 3 MUST failures
+- `2025-12-22-session-64-guardrails-task-validation.md`: 3 MUST failures
+- `2025-12-22-session-65-guardrails-analyst-critique.md`: 3 MUST failures
+
+**Pattern**: Session files from merge conflict work did NOT complete protocol requirements
+
+### Hypotheses (Unverified)
+
+**Hypothesis 1**: Merge-resolver skill lacks session protocol awareness
+
+- **Basis**: No reference to SESSION-PROTOCOL.md in merge-resolver code
+- **Testable**: Review merge-resolver workflow for protocol compliance steps
+- **Validation needed**: Check if other merge-resolver runs have same pattern
+
+**Hypothesis 2**: Template auto-resolution creates stale generated files
+
+- **Basis**: Template updated to main, but copilot-cli/vs-code-agents outputs not regenerated
+- **Testable**: Check if PR #246 has template vs generated file drift
+- **Validation needed**: Run `Generate-Agents.ps1 -Validate` on PR #246 branch
+
+## 5. Results
+
+### Root Cause
+
+**Primary**: Merge-resolver lacks template regeneration step
+
+When merge-resolver auto-accepts main's template version:
+1. `templates/agents/*.shared.md` updated to main version
+2. Platform-specific outputs (`src/copilot-cli/*.agent.md`, etc.) remain at PR branch version
+3. CI check `validate-generated-agents.yml` detects drift
+4. Result: SHOULD fail but actually PASSED in PR #246 (indicates PR already had regeneration)
+
+**Secondary**: Session protocol validation failures are UNRELATED
+
+Session files in PR #246 failed validation because:
+1. Guardrails analysis work (Sessions 62-67) created session logs
+2. Session logs did NOT complete Session End checklist
+3. Protocol compliance sections incomplete
+4. Unrelated to template sync issue
+
+### Key Metrics
+
+| Metric | Value | Source |
+|--------|-------|--------|
+| Template sync check status | PASS | PR #246 CI checks |
+| Session protocol failures | 9 MUST violations | CI logs |
+| Auto-resolvable template patterns | 3 depth levels | Resolve-PRConflicts.ps1 |
+| Session files with violations | 3 of 10 | Session protocol report |
+
+## 6. Discussion
+
+### Misdiagnosis Pattern
+
+**User statement**: "template sync check often fails after merge conflict resolution"
+
+**Actual failure**: Session protocol validation
+
+**Confusion source**:
+1. Both checks run on PR #246
+2. Session protocol check is BLOCKING (fails CI)
+3. Template sync check PASSED
+4. User conflated two unrelated failures
+
+### Template Sync Is NOT The Problem
+
+**Evidence**:
+- `Validate Generated Files: PASS` in PR #246
+- Commit 24063c5 shows template AND generated files updated together
+- `build/Generate-Agents.ps1` was run before push
+
+**Conclusion**: Template sync validation is WORKING CORRECTLY
+
+### Actual Gap: Session Protocol in Merge Resolution
+
+**Pattern identified**:
+1. Agent resolves merge conflicts
+2. Agent creates session log for resolution work
+3. Agent pushes without completing session protocol
+4. CI detects incomplete session logs
+5. Merge blocked
+
+**Missing step**: Session End validation before push
+
+## 7. Recommendations
+
+| Priority | Recommendation | Rationale | Effort |
+|----------|----------------|-----------|--------|
+| P0 | Add session protocol validation to merge-resolver pre-push | Prevents incomplete sessions from blocking CI | Medium |
+| P0 | Update user's mental model: issue is session protocol, not templates | Correct diagnosis enables correct fix | Low |
+| P1 | Add template regeneration check to merge-resolver | Ensures templates and generated files stay in sync | Low |
+| P1 | Document session protocol requirements in merge-resolver SKILL.md | Prevents future agents from repeating pattern | Low |
+| P2 | Create pre-push validation script for merge-resolver | Automates compliance checks | Medium |
+
+### P0 Recommendation Detail: Session Protocol Pre-Check
+
+**Add to merge-resolver workflow**:
+
+```markdown
+## Step 7: Validate Session Protocol (NEW)
+
+Before pushing resolved conflicts:
+
+```bash
+# Validate session log completion
+pwsh scripts/Validate-SessionEnd.ps1 -SessionLogPath ".agents/sessions/[session-log].md"
+
+# Exit code 0 = PASS, continue to push
+# Exit code 1 = FAIL, block push
+```
+
+**When to run**: After conflict resolution, before `git push`
+
+**What it checks**:
+- Session End checklist completed
+- Protocol Compliance section filled
+- Evidence recorded (commit SHA, validation result)
+- Memory updated
+
+**Failure action**: Abort push, prompt agent to complete session protocol
+```
+
+### P1 Recommendation Detail: Template Regeneration
+
+**Add after auto-resolving templates**:
+
+```powershell
+# Check if templates were auto-resolved
+$templatesResolved = $result.FilesResolved | Where-Object { $_ -like 'templates/*' }
+
+if ($templatesResolved) {
+    Write-Host "Templates were auto-resolved. Regenerating platform outputs..." -ForegroundColor Cyan
+
+    # Regenerate from templates
+    & ./build/Generate-Agents.ps1
+
+    # Stage generated files
+    git add src/copilot-cli/*.agent.md src/vs-code-agents/*.agent.md
+
+    Write-Host "Platform outputs regenerated and staged" -ForegroundColor Green
+}
+```
+
+## 8. Conclusion
+
+**Verdict**: User complaint is MISIDENTIFIED - Template sync works correctly
+
+**Confidence**: High
+
+**Rationale**:
+1. PR #246 template validation PASSED
+2. Actual failure was session protocol validation (9 MUST violations)
+3. Template auto-resolution + regeneration workflow is functioning
+4. Gap is in session protocol awareness during merge resolution
+
+### User Impact
+
+**What changes for you**: Understand that the blocker is session protocol compliance, not template sync
+
+**Effort required**: Complete session protocol requirements before claiming merge resolution is done
+
+**Risk if ignored**: Continued CI failures on session protocol validation, wasted investigation time on wrong root cause

+6. Push
+```
+
+### Pre-Check Requirements
+
+**MUST complete before push**:
+- [ ] Session log created at `.agents/sessions/YYYY-MM-DD-session-NN.md`

+- [ ] `pwsh scripts/Validate-SessionEnd.ps1` passed
+
+**Validation Gate**:
+```bash
+# Before allowing push in merge-resolver
+if [ -f ".agents/sessions/$(date +%Y-%m-%d)-session-*.md" ]; then
+    pwsh scripts/Validate-SessionEnd.ps1 -SessionLogPath "$session_log"
+    if [ $? -ne 0 ]; then
+        echo "ERROR: Session protocol validation failed"
+        echo "Complete session requirements before pushing"
+        exit 1
+    fi
+fi
+```
