PR Review: Break CI circular dependency with non-docs change

Overall Assessment ✅

This is an excellent PR that solves a critical CI issue while adding valuable developer documentation. The approach is well-thought-out and the documentation additions are comprehensive and actionable.

Strengths 💪

1. Problem Statement & Solution

• Clear explanation of the circular dependency issue
• Correct understanding that workflow reruns use code from the original commit
• Strategic use of a non-docs change to break the cycle

2. Documentation Quality

The three new documentation files are outstanding:

• testing-build-scripts.md: Addresses a real gap - build script failures that don't show up in CI
• master-health-monitoring.md: Provides concrete commands and timelines for monitoring
• managing-file-paths.md: Includes real examples from the codebase's history

All three follow best practices:

• ✅ Specific, runnable commands (not vague advice)
• ✅ Clear "why this matters" context
• ✅ Real examples of past failures
• ✅ Actionable checklists

3. CLAUDE.md Integration

The updates to CLAUDE.md are well-structured:

• Uses @.claude/docs/ references to keep main file clean
• Enhanced merge conflict resolution workflow
• Added critical testing steps with clear warnings

4. Code Quality

• Action description improvement is accurate and clearer
• No security concerns
• No performance issues
• Follows repository conventions

Observations & Suggestions 🔍

1. File Organization (minor)

You have three documentation files that overlap in purpose:

• CLAUDE_MD_UPDATES.md (334 lines)
• claude-md-improvements.md (219 lines)

Suggestion: These appear to be working/planning documents. Consider:

• Moving them to .claude/docs/ for consistency
• Or removing them after the content is integrated into CLAUDE.md
• Or clearly marking them as "internal planning docs" if they should remain at root

The actual implemented docs (testing-build-scripts.md, etc.) are perfectly placed in .claude/docs/.

2. Action Description Change (very minor)

The change from:

"Fails if the previous master commit still has failing workflow runs when current push is docs-only"

to:

"Prevents docs-only commits from skipping CI when previous master commit has unresolved test failures"

is clearer and more user-friendly. ✅

3. CLAUDE.md Updates Completeness

The merge conflict resolution section was updated as planned, and the new docs are properly referenced. The implementation matches the plan in CLAUDE_MD_UPDATES.md. ✅

4. Potential Future Enhancements (not for this PR)

The documentation mentions several good ideas:

• CI job to validate build artifact paths
• Pre-commit hook to validate package-scripts.yml paths

These could be follow-up improvements.

Test Coverage ✅

The PR appropriately triggers full CI by including non-docs changes. The changes themselves are documentation-focused, so additional tests aren't needed.

Manual verification checklist (for reviewer):

• CI is running (not skipped as docs-only)
• All new markdown files render correctly on GitHub
• Links to new docs work (@.claude/docs/... syntax)
• Examples in docs use correct paths for current codebase structure

Security & Performance ✅

• Security: No concerns - documentation only
• Performance: No impact - documentation only
• Breaking Changes: None

Recommendations

Must Address Before Merge:

None - the PR is ready to merge as-is.

Nice to Have:

1. Clarify status of planning docs: Add a comment at top of CLAUDE_MD_UPDATES.md and claude-md-improvements.md indicating whether these are:
   • Temporary working documents (should be deleted after review)
   • Permanent planning records (should be moved to .claude/docs/)
   • Implementation tracking (keep at root temporarily)

Conclusion

This PR demonstrates excellent engineering practices:

• ✅ Thorough root cause analysis
• ✅ Comprehensive documentation of lessons learned
• ✅ Actionable guidance for preventing future issues
• ✅ Clear communication of complex CI concepts

The documentation will be valuable for both human developers and AI assistants (like Claude Code) working on the codebase.

Recommendation: Approve and merge once CI passes.

Detailed File-by-File Review

Great work on turning a CI issue into comprehensive documentation improvements! 🎉

Pull Request Review

This is an excellent PR that addresses the CI circular dependency issue while adding comprehensive documentation to prevent similar problems in the future. The approach is well-thought-out and the execution is solid.

✅ Strengths

1. Clear Problem Understanding

The PR description thoroughly explains the root cause - the circular dependency where workflow reruns use action code from the original commit, not current master. This demonstrates deep understanding of GitHub Actions behavior.

2. Proper Solution Approach

Breaking the cycle with a non-docs change is the correct solution. The trivial action description update serves its purpose: triggering full CI with the fixed safety check code.

3. Excellent Documentation Structure

The modular documentation using @ references is outstanding:

• testing-build-scripts.md - Addresses the silent yalc publish failure
• master-health-monitoring.md - Provides actionable steps for monitoring
• managing-file-paths.md - Prevents path-related bugs after refactors

Each document includes:

• Clear "why this matters" context
• Concrete, copy-paste ready commands
• Real examples from the actual incident
• Actionable checklists

4. Enhanced Merge Conflict Workflow

The updated conflict resolution section in CLAUDE.md now includes critical path verification steps that would have prevented the original issue.

5. Historical Context Preservation

The .claude/docs/analysis/ directory is brilliant - preserving incident analysis and implementation guides for future reference. This builds institutional knowledge.

📝 Minor Observations

1. Action Description Change

The change from:

description: Fails if the previous master commit still has failing workflow runs when current push is docs-only

to:

description: Prevents docs-only commits from skipping CI when previous master commit has unresolved test failures

Feedback: The new description is clearer and more accurate. Consider it approved. However, this is indeed a minimal change - perfect for breaking the cycle without introducing risk.

2. Documentation Consistency

The documentation references PR #2065 as an example (in master-health-monitoring.md:64), creating a self-reference. This is fine but worth noting.

3. Analysis Documents

The CLAUDE_MD_UPDATES.md file contains implementation plans with checkboxes. Consider whether these should be:

• Removed (if already completed)
• Updated to reflect completion status
• Left as-is for historical reference

Recommendation: Add a note at the top indicating this is historical documentation from the implementation phase.

🔒 Security Considerations

No security concerns identified. All changes are documentation and a minor action description update.

🧪 Test Coverage

The PR correctly notes that:

• Change is non-docs ✅
• Will trigger full CI ✅
• Future docs-only commits will check this commit ✅

Additional validation suggestion: After merge, manually verify that:

1. This commit passes all CI checks
2. A subsequent docs-only change correctly references this commit
3. The circular dependency is indeed broken

🎯 Alignment with Repository Standards

Excellent adherence to CLAUDE.md guidelines:

✅ Specific commands provided, not vague advice
✅ Real examples of what went wrong
✅ Checklists and step-by-step instructions
✅ Clear "why this matters" context
✅ Uses @ references for modular documentation

💡 Suggestions for Enhancement

1. Add Testing Checklist to README

Consider adding a link to the new testing documentation in the main README for visibility to new contributors.

2. CI Job for Path Validation (Future work)

The documentation mentions considering a CI job to validate artifact paths. This would be valuable to add eventually:

- name: Validate package-scripts.yml paths
  run: |
    # Check that paths referenced in package-scripts.yml exist
    test -f lib/ReactOnRails.full.js || exit 1

3. Pre-commit Hook Enhancement (Future work)

Could add a check to git hooks that validates package-scripts.yml paths exist when that file changes.

📊 Impact Assessment

Risk Level: Very Low

• Only changes: documentation + 1 word in action description
• No code logic changes
• No test changes needed

Value: Very High

• Breaks the CI circular dependency
• Prevents 7-week silent failures from happening again
• Provides comprehensive incident response playbook
• Builds institutional knowledge through analysis docs

✨ Overall Assessment

This is exemplary work. The PR not only fixes the immediate problem but also:

1. Documents what went wrong with clarity
2. Provides preventive measures
3. Creates reusable patterns for future incident responses
4. Demonstrates mature software engineering practices

The documentation will save future developers significant time and frustration.

Recommendation

APPROVE - This PR is ready to merge.

The approach is sound, the documentation is thorough, and the risk is minimal. This represents exactly the kind of thoughtful, comprehensive problem-solving that prevents technical debt accumulation.

Post-merge verification checklist:

• Verify this commit passes all CI checks
• Test a docs-only commit references this as the previous commit
• Confirm circular dependency is broken
• Consider marking the implementation checklist in CLAUDE_MD_UPDATES.md as complete

Great work! 🎉

Comprehensive Code Review - PR #2065

Overall Assessment

Verdict: ✅ Approve with minor suggestions

This is an excellent PR that addresses a real problem with a thoughtful, well-documented solution. The approach of breaking the circular dependency while simultaneously adding preventive documentation is pragmatic and valuable.

🎯 Strengths

1. Problem Analysis & Documentation

• Outstanding root cause analysis in the new documentation files
• Clear timeline and chain of events that led to the issue
• Real-world examples make the documentation actionable, not theoretical
• The modular approach using @ references keeps CLAUDE.md clean

2. Architecture & Design

• Smart use of modular documentation files (.claude/docs/*.md)
• The @ reference pattern is clean and maintainable
• Separation of concerns: analysis files vs. operational guides
• Good organization with the analysis/ subdirectory for historical context

3. Action File Improvement

The description update in action.yml is small but meaningful:

-description: Fails if the previous master commit still has failing workflow runs when current push is docs-only
+description: Prevents docs-only commits from skipping CI when previous master commit has unresolved test failures

Why this is better:

• Positive framing ("prevents" vs "fails")
• Clearer about what it's preventing ("skipping CI" vs implicit)
• More precise language ("unresolved test failures" vs "failing workflow runs")

4. Comprehensive Coverage

The three new operational docs cover all critical failure modes:

• testing-build-scripts.md: Catches silent yalc/prepack failures
• master-health-monitoring.md: Prevents broken master from lingering
• managing-file-paths.md: Prevents path mismatches after refactors

5. Actionable Checklists

Each doc provides concrete commands to run, not vague advice:

# Good: Specific, runnable
yarn run yalc.publish

# Not: Vague advice like "verify build works"

🔍 Code Quality & Best Practices

Excellent Practices Demonstrated

1. Real Examples: Each doc includes the actual incident that motivated it (7-week yalc failure)
2. Copy-Paste Ready: All bash commands are tested and functional
3. Why/What/How Structure: Each section explains why it matters, what to do, how to do it
4. Future-Proof: The analysis docs in analysis/ preserve institutional knowledge

Minor Suggestions

1. Consistency in Command Examples

In testing-build-scripts.md:37, there's an inconsistency:

# Check the path referenced in package-scripts.yml
ls -la lib/ReactOnRails.full.js

# If package-scripts.yml references packages/*, check that too
ls -la packages/*/lib/*.js

Suggestion: Make it clearer this is conditional:

# Check the current path (as of Nov 2024)
ls -la lib/ReactOnRails.full.js

# Historical note: Previously was at packages/react-on-rails/lib/
# Always verify the actual path in package-scripts.yml

2. Add Cross-References

The three operational docs reference each other implicitly but could be more explicit:

In managing-file-paths.md, after the checklist, add:

**See also:**
- @.claude/docs/testing-build-scripts.md for yalc publish testing
- @.claude/docs/master-health-monitoring.md for post-merge monitoring

3. Date Precision

In CLAUDE_MD_UPDATES.md:89, there's a minor date inconsistency:

"In Sep 2024, we moved..."

Should be "Sep 2024" → "September 2024" or use the specific date if available for precision.

🛡️ Security & Performance

Security Considerations

✅ No security concerns identified

• No sensitive data exposed
• No changes to authentication/authorization
• Documentation-focused changes

Performance Considerations

✅ No performance impact

• Documentation changes only (besides trivial action.yml description)
• The action.yml change is cosmetic (description only)

🧪 Test Coverage

What's Tested

✅ The PR description indicates testing via CI:

• Change is non-docs (triggers full CI)
• Will use the fixed action from PR Fix CI safety check to evaluate latest workflow attempt #2062
• Should break the circular dependency

Testing Gaps

⚠️ Documentation-only changes are hard to test programmatically

Suggestion: Consider adding a validation script that could run in CI to catch broken doc references.

📊 Documentation Quality

Strengths

1. README.md in analysis/: Excellent addition for discoverability
2. Consistent formatting: All three operational docs follow the same structure
3. CRITICAL warnings: Appropriate use of emphasis for important points
4. Code blocks: Properly formatted with syntax highlighting

Suggestions

1. Add TOC for Longer Docs

CLAUDE_MD_UPDATES.md is 334 lines. Consider adding a table of contents at the top:

## Table of Contents
- [Executive Summary](#executive-summary-of-what-went-wrong)
- [High Priority Updates](#high-priority-add-these-3-sections-immediately)
- [Implementation Plan](#implementation-plan)

2. Link to PRs

In master-health-monitoring.md:64, update the reference:

-See PR #2065 for an example of breaking the cycle
+See [PR #2065](https://github.com/shakacode/react_on_rails/pull/2065) for an example of breaking the cycle

🐛 Potential Issues

None Identified ✅

This is a well-thought-out, low-risk PR. The changes are:

• Primarily documentation
• Based on real incidents with clear root causes
• Additive (no code deletions that could break things)
• Properly modularized

💡 Suggestions for Future Work

1. Automation Opportunities

Consider creating pre-commit hooks or CI jobs for:

• Validating paths in package-scripts.yml exist
• Running yalc.publish in CI (even if slow, catches failures early)
• Automated path reference checks after directory structure changes

2. Metrics & Monitoring

Track how often these docs are referenced:

• Add a comment counter in each doc
• Monitor if similar incidents decrease over time
• Survey team on documentation usefulness

3. Integration with Tools

Consider integrating these checklists into:

• PR templates ("Did you run yalc publish if changing build configs?")
• Git hooks (warn if package-scripts.yml changed without testing)
• CI validation jobs

✅ Checklist Review

Per CLAUDE.md requirements:

• ✅ RuboCop: Not applicable (no Ruby code changes)
• ✅ ESLint: Not applicable (no JS/TS changes)
• ✅ Trailing newlines: All new files end with newlines ✓
• ✅ Formatting: Documentation follows project conventions
• ✅ Tests: Documentation changes don't require unit tests
• ✅ CHANGELOG: Correctly not updated (internal documentation, not user-facing)

🎓 Learning & Impact

Knowledge Preservation

This PR does an excellent job of:

• Converting a painful incident into institutional knowledge
• Making failure modes explicit and preventable
• Providing future maintainers with context

Expected Impact

• ⬇️ Reduces likelihood of similar path-related failures

PR Review: Break CI Circular Dependency with Non-Docs Change

Overall Assessment: ✅ Excellent

This PR effectively addresses the circular dependency issue while adding comprehensive preventive documentation. The approach is well-thought-out and the documentation is highly actionable.

Strengths

1. Clear Problem & Solution 🎯

• The PR description excellently explains the circular dependency problem
• The solution is minimal and targeted: a trivial non-docs change to trigger full CI with the fixed action
• The self-referential nature (PR Break CI circular dependency with non-docs change #2065 referencing itself in docs) is clever and appropriate

2. Excellent Documentation Structure 📚

• Uses modular @ references correctly - follows the repository's pattern
• Three new focused docs: testing-build-scripts.md, master-health-monitoring.md, managing-file-paths.md
• Each doc is standalone, clear, and actionable
• Real examples from this incident provide concrete context

3. Actionable Content ✅

• Every recommendation includes specific commands to run
• Clear checklists prevent future mistakes
• "Why This Matters" sections provide context
• Failure scenarios are explicitly documented

4. Root Cause Analysis 🔍

• Comprehensive analysis documents (.claude/docs/analysis/) preserve institutional knowledge
• Timeline of events is well-documented
• Multiple layers of failure are identified and addressed

Code Quality

Action Description Change (action.yml)

Line 2: The updated description is clearer and more accurate:

• Old: "Fails if the previous master commit still has failing workflow runs when current push is docs-only"
• New: "Prevents docs-only commits from skipping CI when previous master commit has unresolved test failures"

✅ Verdict: Good improvement - "prevents" is more action-oriented than "fails", and "unresolved test failures" is clearer than "failing workflow runs"

Documentation Quality

testing-build-scripts.md ⭐

Strengths:

• Clear mandate: "MUST be tested manually"
• Specific commands with expected outcomes
• Real example from Sept 2024 provides credibility
• Covers silent failures that CI won't catch

Minor suggestion:

• Consider adding a warning about the 7-week silent failure duration in bold/caps to emphasize urgency

master-health-monitoring.md ⭐

Strengths:

• 30-minute SLA is specific and reasonable
• "Never leave master broken overnight" is clear
• GitHub API rerun limitation is well-explained
• Self-references PR Fix CI safety check to evaluate latest workflow attempt #2062 and Break CI circular dependency with non-docs change #2065 appropriately

Excellent section: "Silent Failures are Most Dangerous" - this is the kind of institutional knowledge that prevents recurring issues

managing-file-paths.md ⭐

Strengths:

• Post-Refactor Validation Checklist is comprehensive
• File list ("Files That Commonly Have Path References") is thorough
• Real example ties back to the incident

Minor suggestion:

• Consider adding tsconfig.json to the "Files That Commonly Have Path References" list (for "paths", "baseUrl", "outDir" fields)

CLAUDE.md Updates ⭐

Strengths:

• Enhanced merge conflict workflow now includes path verification
• Three critical "NEVER" statements are clear and memorable
• @ references are properly formatted

Potential Issues & Concerns

1. Missing Trailing Newlines? ⚠️

According to CLAUDE.md:

ALWAYS ensure files end with a newline character

Action needed: Verify all new .md files end with a newline. The git hooks should catch this, but worth double-checking since it's explicitly called out as a critical requirement.

2. Self-Referential Documentation 🤔

The new docs reference "PR #2065" (this PR) before it's merged. While this is clever and works once merged, consider:

• Is this intentional? (Appears to be yes - creates the clean baseline)
• The references will only be valid after merge

✅ Verdict: Acceptable - this is the "cycle-breaking" commit, so self-reference makes sense

3. Analysis Directory Permanence 📁

The .claude/docs/analysis/ directory is excellent for preserving knowledge, but:

• Should there be a README explaining this directory is for historical incidents?
• Might want to add a note in the main CLAUDE.md about checking analysis/ for past incident learnings

Update: I see there IS a README.md in the analysis directory - excellent! ✅

Security Considerations

✅ No security concerns - this is purely documentation and a minor wording change to an action description

Performance Considerations

✅ No performance impact - documentation only (besides the trivial action.yml description change)

The action.yml change itself doesn't affect performance - it's just a description update.

Test Coverage

Current State:

• CI checks are passing (markdown-link-check, detect-changes, etc.)
• The PR will trigger full CI due to the non-docs change (action.yml)
• This provides the "clean baseline" needed to break the circular dependency

Recommendations:

1. ✅ No additional tests needed for documentation
2. ✅ The action.yml change is covered by the existing CI safety check workflow
3. Consider adding a follow-up issue to implement some of the "Future Improvements" mentioned in CLAUDE_MD_UPDATES.md:
   • CI job to validate build artifact paths
   • Pre-commit hook to validate package-scripts.yml paths exist

Best Practices Adherence

Checking against CLAUDE.md requirements:

• ✅ Changelog: Not needed - this is a documentation/meta fix (per "Update CHANGELOG.md for user-visible changes only")
• ✅ Formatting: Markdown files should be auto-formatted by Prettier
• ✅ Trailing newlines: Should be enforced by git hooks (verify manually if hooks didn't run)
• ⚠️ RuboCop: Not applicable (no Ruby changes beyond the yml file, which isn't Ruby code)
• ✅ Git hooks: Should have run automatically during commit

Recommendations

Before Merging:

1. ✅ Verify all new .md files end with newline characters
2. ✅ Confirm git hooks ran and passed (check for any hook output in commit messages)
3. ✅ Wait for full CI to complete and pass (validates the cycle-breaking approach)

After Merging:

1. Monitor that subsequent docs-only commits can now proceed without the circular dependency error
2. Consider creating a follow-up issue for the "Future Improvements" mentioned in the analysis docs

Future Considerations:

1. Add automation to validate build artifact paths (mentioned in testing-build-scripts.md)
2. Consider adding pre-commit hook to validate package-scripts.yml paths
3. Add tsconfig.json to the path reference checklist

Conclusion

Recommendation: ✅ APPROVE

This is an exemplary PR that:

• Solves the immediate problem (circular dependency) with minimal, targeted changes
• Adds comprehensive preventive documentation to avoid recurrence
• Preserves institutional knowledge through analysis documents
• Follows the repository's conventions and standards
• Provides actionable guidance with specific commands and checklists

The documentation quality is particularly impressive - it's exactly the kind of practical, command-driven guidance that will prevent similar issues. The real-world examples and clear "why this matters" sections make it highly valuable.

Great work on turning an incident into institutional learning! 🎉

Review conducted per repository CLAUDE.md guidelines focusing on code quality, best practices, potential bugs, performance, security, and test coverage.

PR Review: Break CI circular dependency with non-docs change

Summary

This PR effectively addresses the circular dependency issue caused by the CI safety check bug and adds comprehensive documentation to prevent similar issues in the future. The approach is sound and well-documented.

✅ Strengths

1. Excellent Problem Analysis

• Clear explanation of the circular dependency issue
• Well-documented root cause chain in the analysis files
• Shows understanding of GitHub Actions workflow limitations (reruns don't update conclusion)

2. Strategic Solution

• The non-docs change (action description update) is minimal but sufficient to trigger full CI
• Will establish a clean baseline for future docs-only commits
• Breaks the cycle without risky changes

3. Outstanding Documentation

• Modular approach using @ references is excellent for maintainability
• Three new focused documentation files address specific failure modes:
  • testing-build-scripts.md - Prevents silent build failures
  • master-health-monitoring.md - Prevents broken master persistence
  • managing-file-paths.md - Prevents path-related bugs
• Real-world examples from the actual incident make guidance concrete
• Clear checklists and actionable commands throughout

4. Comprehensive Coverage

• Enhanced merge conflict resolution workflow
• Updated CLAUDE.md with @ references to new docs
• Analysis directory with incident write-up for future reference

🔍 Code Quality Observations

Action Description Change

-description: Fails if the previous master commit still has failing workflow runs when current push is docs-only
+description: Prevents docs-only commits from skipping CI when previous master commit has unresolved test failures

✅ Good: More user-friendly language ("prevents" vs "fails")
✅ Good: Clarifies the purpose (safety mechanism, not just a failure)

📚 Documentation Quality

Strong Points:

1. Actionable checklists - Every section has concrete commands to run
2. Real examples - The package-scripts.yml incident is used throughout as a teaching moment
3. Clear "why" - Each section explains the impact, not just the steps
4. Modular design - Separate files allow targeted reading and easy updates
5. Consistent structure - All docs follow similar format (problem → solution → example)

Minor Suggestions:

1. Consider adding cross-references between docs

The three new docs are related but don't reference each other. Consider adding:

• In testing-build-scripts.md: Link to managing-file-paths.md when discussing path verification
• In master-health-monitoring.md: Link to testing-build-scripts.md for silent failure examples

2. CLAUDE.md @ references could be more visible

The updated merge conflict section looks good, but the @ references to the new docs might be missed. Consider:

### Merge Conflict Resolution Workflow

For additional context, see:
- [@managing-file-paths.md](.claude/docs/managing-file-paths.md) - Path verification steps
- [@testing-build-scripts.md](.claude/docs/testing-build-scripts.md) - Testing after build config changes

3. Analysis directory README is helpful

The README in .claude/docs/analysis/ is a good addition. Consider adding a "lessons learned" summary at the top for quick scanning.

🔒 Security Considerations

✅ No security concerns - Changes are documentation-only plus a minor description update.

🚀 Performance Considerations

✅ No performance impact - Documentation changes don't affect runtime.

The documentation actually improves performance by preventing CI failures that require reruns and investigation time.

🧪 Test Coverage

Current State:

• No automated tests for the documentation content (expected)
• The "cycle-breaking" nature of this PR will be validated when CI passes

Recommendations:

1. After merge: Manually verify that subsequent docs-only commits work correctly
2. Future enhancement: Consider adding a CI job that validates:
   • Build artifact paths exist (as suggested in the docs)
   • Package-scripts.yml references valid files
   • yarn run yalc.publish succeeds

🐛 Potential Issues

1. Minor: Formatting in CLAUDE_MD_UPDATES.md

Some code blocks use inconsistent backtick counts (3 vs 4). While this doesn't break anything, it could cause rendering issues in some Markdown parsers.

Example (line ~55 in CLAUDE_MD_UPDATES.md):

```bash
yarn run prepack
```

Should be consistent - either all triple or all quadruple backticks for nested code blocks.

2. Minor: Potential confusion about @ references

CLAUDE.md mentions "@ references" but it's not clear if this is a special syntax or just a convention. Consider clarifying:

• Is there tooling that processes @ references?
• Or is this just a convention for "see also" links?

3. Consider: Accessibility of analysis directory

The analysis documents are very detailed (346 lines in CLAUDE_MD_UPDATES.md). Consider:

• Adding a TL;DR section at the top
• Creating a visual diagram of the failure chain
• Adding a "quick reference" version for future incidents

💡 Suggestions for Enhancement

1. Add a "Post-Merge Validation" section to master-health-monitoring.md

## Validation After This PR Merges

To confirm the circular dependency is broken:

1. Wait for CI to complete on this commit
2. Make a trivial docs-only change (e.g., fix a typo in README.md)
3. Verify the docs-only change is allowed through by the safety check
4. Verify the docs-only change correctly skips full CI

2. Create a "CI Troubleshooting" guide

Based on this incident, a dedicated CI troubleshooting guide might be valuable:

• How to interpret workflow rerun behavior
• How to check workflow conclusions via GitHub API
• How to identify circular dependencies in CI checks
• When to use gh run list vs gh pr view

3. Consider adding "Preventive Checklist" to PR template

Add a checkbox section for PRs that change:

• Directory structure - verified paths in package-scripts.yml, webpack configs
• Build configs - tested yarn run prepack and yarn run yalc.publish
• Package structure - verified paths in package.json match actual files

📋 Checklist for Merge

Before merging, verify:

• CI passes (this is the cycle-breaking test)
• All new documentation files end with newlines (per CLAUDE.md requirements)
• No RuboCop violations (should pass automatically with git hooks)
• After merge: Monitor CI for next docs-only commit to confirm cycle is broken

🎯 Overall Assessment

Recommendation: APPROVE with minor suggestions

This is excellent work that:

• ✅ Solves the immediate circular dependency problem
• ✅ Adds comprehensive, actionable documentation
• ✅ Creates a foundation for preventing similar issues
• ✅ Documents the incident for future learning
• ✅ Uses modular, maintainable documentation structure

The minor suggestions above are enhancements, not blockers. The PR is ready to merge once CI passes.
