root_causes:

    affected_runs: 1
    severity: critical

    resolution_time_minutes: 13
  - issue_id: RCA-002
    symptom: Parallel test race conditions causing cascade failures
    root_cause: Multiple test workers simultaneously modifying global process.cwd() state

    severity: high
    fix: "Set maxWorkers: 1 in jest.config.js for sequential execution"
    prevention: Meta-test validates sequential execution enforcement
    resolution_time_minutes: 13
  - issue_id: RCA-003
    symptom: MODULE_NOT_FOUND for ${CLI_PATH}
    root_cause: Template literal syntax bug - used single quotes instead of
      backticks (11 instances)
    affected_tests: drift.test.ts
    instances: 11
    severity: medium
    fix: Replaced all execSync('node ${VAR}') with execSync(`node ${VAR}`)
    prevention: Meta-test now automatically scans all test files for this pattern
    resolution_time_minutes: 7

      failures when those test branches executed
