system at docs/test-hygiene/orphaned-process-verification.md

The documentation includes:
- Overview of orphaned process verification and why it matters
- Usage instructions for scripts/check-orphaned-processes.sh
- Verification methods (shell script, Rust helpers, CI integration)
- Best practices for RAII guards and process cleanup
- CI integration examples
- Troubleshooting guide

Verification Note for bf-1lghw6

Task

Create orphaned process verification documentation file with basic structure.

Implementation Summary

Created comprehensive documentation at docs/test-hygiene/orphaned-process-verification.md that includes:

Overview Section

  • Explains what orphaned process verification is
  • References the test hygiene rules from CLAUDE.md
  • Describes the problem: tests spawning subprocesses can leave orphans

Usage Instructions

  • Shell script usage examples (./scripts/check-orphaned-processes.sh)
  • All command-line options: --json, --kill, --verbose, --pattern
  • Exit codes and their meanings
  • JSON output format specification

Rust Test Helpers

  • In-test verification using process_guard module
  • Code examples for RAII guards

Best Practices

  • RAII guards for process spawning
  • Verification at test boundaries
  • Using timeouts on all waits (never bare child.wait())
  • Using Stdio::null() for long-running servers

CI Integration

  • Example bash script for post-test checks
  • Exit code handling

Troubleshooting

  • How to identify and clean up orphaned processes
  • How to find leaking tests
  • Dependency requirements (pgrep)

Acceptance Criteria Status

PASS

  • Documentation file exists at docs/test-hygiene/orphaned-process-verification.md
  • Contains clear overview of orphaned process verification (Overview + Problem Statement sections)
  • Includes basic usage instructions for the verification script (Verification Methods section with examples)
  • References the verification script at scripts/check-orphaned-processes.sh (multiple references)
  • Explains the purpose (test hygiene, preventing hung tests) - covered in Overview, Problem Statement, and Best Practices

Files Created

  • docs/test-hygiene/orphaned-process-verification.md (241 lines)
  • scripts/check-orphaned-processes.sh (verification script, already exists)
  • CLAUDE.md (test hygiene rules)
  • Bead bf-5xh7g: Orphaned process verification implementation
  • Bead bf-119ys: TH-03 process cleanup with RAII guards

Test Results

N/A - Documentation-only task, no executable code to test

Conclusion

The documentation successfully provides a comprehensive guide to orphaned process verification, meeting all acceptance criteria. The file is ready to be committed and pushed to the repository.
