Deep Verification Details

PendingMigrationsVerifier Implementation

• Pattern compliance: Follows SolidQueueVerifier pattern exactly (DI constructor, call method, Result return, rescue block)
• Migration filtering: Correctly filters to only source_monitor migrations (line 63: name.include?("source_monitor"))
• Timestamp handling: Strips timestamps using MIGRATION_TIMESTAMP_PATTERN regex (lines 7, 75)
• Branch coverage: 5 tests cover all branches:
  1. All present + not pending (ok)
  2. Missing migrations (warning)
  3. Pending migrations (warning)
  4. Non-SM migrations ignored (ok)
  5. Unexpected errors (error)

UpgradeCommand Implementation

• Version detection: Compares stored vs current version (lines 21-25)
• Orchestration: Calls migration_installer.install, install_generator.run, verifier.call in sequence (lines 27-29)
• Version marker timing: write_version_marker called AFTER verifier.call (line 30), ensuring failed verification prevents marker update
• Up-to-date handling: Returns ok Summary with upgrade Result when versions match (lines 48-56)
• Branch coverage: 5 tests cover all branches:
  1. Versions match (up-to-date)
  2. Versions differ (full upgrade)
  3. Version file missing (fresh install)
  4. Verification raises (marker not written)
  5. Plain text marker format

CLI Integration

• Delegation pattern: Matches install and verify commands (lines 27-31)
• Error handling: Uses handle_summary to exit(1) on non-ok summary
• Test coverage: 1 test verifying delegation to UpgradeCommand and printer

Runner Wiring

• Verifier order: PendingMigrationsVerifier is first (line 21), ensuring migration status checked before other verifiers
• Test update: Runner test updated to expect 4 verifiers instead of 3 (9 assertions)

Autoload Declarations

• Setup module: UpgradeCommand autoloaded at line 172
• Verification module: PendingMigrationsVerifier autoloaded at line 178
• Pattern: Matches existing autoload declarations for Setup and Verification modules

Issues Found

None. All 34 checks passed.

Summary

Tier: deep (30+ checks)

Result: PASS

Passed: 34/34

Failed: None

Notes:

• The release_packaging_test error is pre-existing and unrelated to Phase 1 changes. It's caused by deleted VBW milestone files in git status that are referenced in the gemspec. This test would fail on the previous milestone as well.
• Total new test count: 11 (5 PendingMigrationsVerifier + 5 UpgradeCommand + 1 CLI)
• Total suite now at 992 runs (up from 981 per summary)
• RuboCop clean: 0 offenses
• Brakeman clean: 0 warnings
• All REQ-26 and REQ-27 acceptance criteria met
• Version marker written AFTER verification (critical for retry safety)
• PendingMigrationsVerifier correctly filters to source_monitor migrations only
• Both classes follow established verifier and command patterns
• Comprehensive test coverage with all branches tested
