# Phase 27 Plan 03: Validate.rs Quiet Gap Closure Summary

**PMCP_QUIET env var guards added to all decorative println! calls in validate.rs, completing --quiet coverage across all 25 command files**

## Performance

- **Duration:** 2 min
- **Started:** 2026-03-04T04:38:18Z
- **Completed:** 2026-03-04T04:39:56Z
- **Tasks:** 1
- **Files modified:** 1

## Accomplishments
- Added PMCP_QUIET env var check to validate_workflows() and threaded not_quiet through all private functions
- Gated all decorative output (banners, progress steps, success messages, guidance text) with if not_quiet guards
- Kept error output unconditional: compilation failed, validation failed, and failure summary detail
- FLAG-09 now fully satisfied across all 25 command files (was 24 of 25 before this fix)

## Task Commits

Each task was committed atomically:

1. **Task 1: Add PMCP_QUIET guards to all decorative output in validate.rs** - `6bc5a29` (feat)

## Files Created/Modified
- `cargo-pmcp/src/commands/validate.rs` - Added not_quiet env var check, gated all decorative println! with if not_quiet guards, threaded not_quiet to run_validation, generate_validation_scaffolding, print_test_guidance

## Decisions Made
- Threaded not_quiet as a bool parameter through run_validation(), generate_validation_scaffolding(), and print_test_guidance() rather than re-checking the env var in each function -- this is consistent with how the value is threaded in similar functions and avoids redundant env var lookups

## 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 27 (Global Flag Infrastructure) is now fully complete with all 3 plans executed
- All 25 command files honor --quiet via either should_output() or PMCP_QUIET env var
- Ready for Phase 28 (Flag Normalization) or any subsequent v1.6 phase

## Self-Check: PASSED

All modified files verified present on disk. Task commit (6bc5a29) verified in git log. SUMMARY.md created.
