• Close Simplify multi-line comment in analyzer/src/main.py #241 (already resolved)

Refactoring

• Add GIT_SHORT_SHA_LENGTH constant to transaction_manager.py (Replace magic number 7 with named constant in git_helper.py #331)
• Add CYAN color constant and update test scripts to source colors.sh (Extract duplicated color codes to shared constants in test scripts #214)

Documentation

• Document sequential plugin execution model in docimp.config.js (Document sequential plugin execution implications in docimp.config.js #290)
• Add git timeout troubleshooting to transaction-integration.md (Document orphaned backup cleanup operational guidance #329)
• Add orphaned backup cleanup instructions (Add troubleshooting guide for git timeout errors #346)
• Close Enhancement: Document MAX_CACHE_SIZE=50 rationale #268, Enhancement: Document concurrent access safety assumptions #269, Add version compatibility note to update-expected-results.sh #213 (already resolved)

Validation

• Add parameter validation to ClaudeClient constructor (Enhancement: Add parameter validation to ClaudeClient constructor #273)
• Add UUID format validation for session IDs (Add UUID format validation for session IDs in Python CLI #322)

UX Improvements

• Add visual cue "(Code hidden - press C to view)" in on-demand audit mode (Add visual cue for on-demand mode in audit code display #226)
• Add stack trace detection to error message validation (Add stack trace detection to error message validation #209)

Code Review Follow-up

• Add --format json support to cmd_rollback_session for consistency
• Add UUID validation to delete-audit-session and delete-improve-session commands
• Extract contains_stack_trace() to reusable test-helpers.sh
• Add isValidUuid() utility function for TypeScript session commands

Test plan

• All 647 Python tests pass
• All 969 TypeScript tests pass (1 pre-existing flaky test cleanup issue)
• Shell script syntax validated
• Linting passes (ruff, eslint)

Code Review: PR #403

Approved with minor suggestions

Successfully addresses 14 backlog issues with high-quality implementations. All tests passing (647 Python + 955 TypeScript = 1,602 tests), comprehensive documentation improvements, and consistent patterns across the polyglot codebase.

Strengths:

• Excellent test coverage with no regressions
• Clean constant extraction (GIT_SHORT_SHA_LENGTH, CYAN color)
• Comprehensive UUID validation with helpful error messages
• Well-structured troubleshooting guides (git timeouts, backup cleanup)
• Good adherence to project patterns (DI, error handling)

Key Findings

Minor (2):

1. Code consistency: cmd_rollback_session UUID validation doesn't support --format json like other transaction commands (minor inconsistency)
2. Documentation: Commit messages reference issues but lack "Fixes #N" keywords for auto-closing

Enhancement Ideas (2):

1. High impact, low effort: Add UUID validation to improve session commands (consistency with transaction commands)
2. Moderate impact, low effort: Extract stack trace detection to reusable test-helpers.sh function

Test Results

• ✓ Python: 647 tests passed
• ✓ TypeScript: 955 tests passed
• ✓ Linting: All checks passed
• ✓ No breaking changes

Detailed Review Highlights

Functional Completeness (11/11 dimensions):

• All 14 issues addressed with complete implementations
• UUID validation: Clean helper function with clear docs
• ClaudeClient validation: Defense-in-depth with specific error messages
• Documentation: Actionable troubleshooting with concrete examples
• UX improvements: Non-intrusive visual cues

Code Quality:

# Excellent constant extraction
GIT_SHORT_SHA_LENGTH = 7  # Standard short SHA (7 hex chars = 28 bits)

# Clear validation with helpful errors
if not validate_session_id(session_id):
    error_msg = f"Invalid session ID format: {session_id}"
    hint = "Expected UUID format (e.g., 550e8400-e29b-41d4-a716-446655440000)"

Cross-Cutting Consistency:

• Python/TypeScript UUID handling aligned
• Consistent error message format across layers
• Test organization maintains valid UUID format

Recommendation

Approve. No blocking issues. Minor suggestions for future improvements don't block merge.

Code Review: PR #403 - 2nd review

Approved - Ready to merge

All previous code review findings successfully addressed. Follow-up commit (a0de484) implemented all 4 suggestions with excellent quality.

Summary

Successfully addresses 14 backlog issues with high-quality implementations across the polyglot codebase. All 1,617 tests passing (647 Python + 970 TypeScript), no linting errors, no breaking changes.

Follow-up Improvements Implemented (4/4)

1. --format json support - Added to cmd_rollback_session for consistency with other transaction commands
2. UUID validation - Added isValidUuid() utility and validation to delete-audit-session and delete-improve-session commands
3. Reusable test helper - Extracted contains_stack_trace() to test-helpers.sh for cross-script use
4. Git keywords - First commit updated with "Fixes Clean up unused LANGUAGE_SPECIFIERS constant in ClaudeResponseParser #239, fixes Remove line number references from test comments #247" for auto-closing
