Phase 2 Plan 2: Doctor Overlay Validation Summary

checkOverlayExists doctor check validates FLYNN_ENV overlay file exists with skip/pass/fail tristate reporting

Performance

• Duration: ~1 min (52s)
• Started: 2026-02-10T04:59:35Z
• Completed: 2026-02-10T05:00:27Z
• Tasks: 1
• Files modified: 1

Accomplishments

• Added checkOverlayExists to flynn doctor checks array
• When FLYNN_ENV is set, reports pass (file found) or fail (file missing with path detail)
• When FLYNN_ENV is not set, check is skipped silently
• Positioned after checkConfigExists, before checkConfigParses for natural validation flow

Task Commits

Each task was committed atomically:

1. Task 1: Add checkOverlayExists to doctor.ts - 6bd3721 (feat)

Files Created/Modified

• src/cli/doctor.ts - Added checkOverlayExists check function and inserted into allChecks array after checkConfigExists

Decisions Made

• Placed overlay check between checkConfigExists and checkConfigParses — validates files exist before attempting to parse/validate them
• Used 'skip' status when FLYNN_ENV is not set to avoid noise for users not using overlays

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Phase 2 (Config Overlays) complete — both overlay merge and doctor validation shipped
• Ready for Phase 3 (Live Ops Dashboard)
