+# PR #135 Review Fixes - Implementation Summary
+
+This document summarizes the fixes applied to address the review comments on PR #135.
+
+## Changes Made
+
+### 1. Supply-Chain Security (addresses review comments #8, #9)
+
+**Problem**: Scripts were dynamically installing npm packages without version pinning using `npm install --no-save`, creating a supply-chain attack vector in CI.
+
+**Fix**: Added pinned devDependencies to `package.json`:
+- `ts-prune@^0.10.3` - AST-based unused export detection
+- `jscpd@^4.0.5` - Code duplication detection
+- `eslint-plugin-complexity@^2.0.1` - Complexity analysis
+
+Removed all `npm install --no-save` commands from:
+- `scripts/analyze-dead-code.sh`
+- `.github/workflows/self-optimize.yml`
+
+All tools now use pinned versions installed via `npm ci` in CI workflows.
+
+### 2. Script Error Handling (addresses review comment #1)
+
+**File**: `scripts/validate-dev-branch.sh`
+
+**Problem**: Used `set -e` without pipeline failure detection, causing silent failures in pipelines.
+
+**Fix**: Changed to `set -euo pipefail` for proper error handling:
+- `-e`: Exit on error
+- `-u`: Exit on undefined variables
+- `-o pipefail`: Fail pipelines if any command fails
+
+Added explicit handling for expected non-zero exits (e.g., `grep -q` that may not match`) without inverting the security check logic.
+
+### 3. Dead Code Analysis Logic (addresses review comment #3)
+
+**File**: `scripts/analyze-dead-code.sh`
+
+**Problem**: Grep-based unused import detection had logical flaws and would incorrectly flag all imports.
+
+**Fix**: 
+- Replaced fragile grep heuristics with ts-prune (AST-based tool)
+- Added `set -euo pipefail` for proper error handling
+- ts-prune provides comprehensive unused export and import detection
+- Output still goes to `/tmp/dead-code-analysis` directory
+
+### 4. Unused Variables (addresses review comments #6, #7)
+
+**File**: `scripts/analyze-coverage-gaps.js`
+
+**Problem**: Unused variables `execSync` and `relativePath` causing lint warnings.
+
+**Fix**:
+- Removed `const { execSync } = require('child_process');` (line 12)
+- Removed `const relativePath = path.relative(process.cwd(), filePath);` (line 141)
+
+### 5. Conditional Risky Patterns Flag (addresses review comment #4)
+
+**File**: `.github/workflows/self-optimize.yml`
+
+**Problem**: `risky_patterns_found` was unconditionally set to `true` even when no patterns were detected.
+
+**Fix**: Made it conditional based on actual findings:
+```bash
+RISKY_FOUND="false"
+if [[ $EVAL_COUNT -gt 0 ]] || [[ $ANY_COUNT -gt 100 ]] || [[ $KEY_COUNT -gt 0 ]]; then
+  RISKY_FOUND="true"
+fi
+echo "risky_patterns_found=$RISKY_FOUND" >> $GITHUB_OUTPUT
+```
+
+### 6. Git Push Error Handling (addresses review comment #5)
+
+**File**: `.github/workflows/self-optimize.yml`
+
+**Problem**: Failed git push was silently ignored with `|| echo "Push failed"`, and documentation implied that automated fixes were still being committed locally.
+
+**Fix**: **Disabled auto-push entirely** per security review and clarified commit behavior:
+- Automated fixes are generated in the workflow run but are neither committed nor pushed with the current `contents: read` permission
+- Auto-push logic is commented out with a security note
+- Prevents pushing or committing potentially broken code to contributor branches
+- Safer approach: generate a separate PR for review or explicitly grant `contents: write` if local commits are ever enabled
+
+### 7. Duplicate Inline Comments (addresses review comment #2)
+
+**File**: `.github/workflows/self-optimize.yml`
+
+**Problem**: Multiple patterns on same line would create duplicate comments.
+
+**Fix**: Added deduplication logic:
+- Uses Map to group comments by `file:line` key
+- Consolidates multiple issues into single comment with numbered list
+- Format: "### Multiple Issues Found" with each issue numbered
+
+### 8. PR Comment Size Reduction
+
+**File**: `.github/workflows/self-optimize.yml`
+
+**Problem**: Full reports in PR comments could be very large.
+
+**Fix**:
+- Summary section with artifact links instead of full reports
+- Only first 10-15 lines of each report as "highlights"
+- Full reports available as workflow artifacts
+- Cleaner, more concise PR comments
+
+### 9. Reduced Workflow Permissions
+
+**File**: `.github/workflows/self-optimize.yml`
+
+**Problem**: Workflow had excessive permissions (`contents: write`, `checks: write`).
+
+**Fix**:
+```yaml
+permissions:
+  contents: read      # Changed from write
+  pull-requests: write
+  issues: write
+  # Removed checks: write (not needed)
+```
+
+## Installation Notes
+
+The new devDependencies need to be installed:
+
+```bash
+npm install
+```
+
+This will update `package-lock.json` with the pinned versions. CI workflows use `npm ci` to install exact versions.
+
+## Testing
+
+### Scripts
+```bash
+# Test validate-dev-branch.sh
+bash scripts/validate-dev-branch.sh
+
+# Test analyze-dead-code.sh
+bash scripts/analyze-dead-code.sh
+
+# Test analyze-coverage-gaps.js
+node scripts/analyze-coverage-gaps.js
+```
+
+### Workflow
+The self-optimize workflow will run on PR creation/update. Review:
+1. PR comments for concise summary
+2. Workflow artifacts for full reports
+3. Inline comments for specific issues
+
+## Deferred Items
+
+None - all review comments have been addressed.
