Phase 14 Plan 01: Phase Dependencies Schema Summary

Phase dependencies table and repository methods mirroring the task_dependencies pattern for parallel execution prerequisite tracking

Performance

• Duration: 2 min
• Started: 2026-02-02T12:31:52Z
• Completed: 2026-02-02T12:33:19Z
• Tasks: 2
• Files modified: 3

Accomplishments

• Added phase_dependencies table to schema with cascade delete FKs
• Extended phases relations with dependsOn and dependents many relations
• Added createDependency, getDependencies, getDependents to PhaseRepository interface
• Implemented all methods in DrizzlePhaseRepository following task dependency pattern
• Exported PhaseDependency and NewPhaseDependency types

Task Commits

Each task was committed atomically:

1. Task 1: Add phase_dependencies table to schema - a55d08f (feat)
2. Task 2: Add dependency methods to PhaseRepository - 8e68a6e (feat)

Files Created/Modified

• src/db/schema.ts - Added phase_dependencies table, phaseDependenciesRelations, extended phasesRelations with dependency relations, exported types
• src/db/repositories/phase-repository.ts - Added createDependency, getDependencies, getDependents method signatures
• src/db/repositories/drizzle/phase.ts - Implemented all three dependency methods

Decisions Made

• Mirrored task_dependencies exactly: same column names (phaseId/dependsOnPhaseId), same FK constraints
• getDependencies and getDependents return string[] (IDs only) rather than full Phase objects for query efficiency
• Used nanoid for dependency IDs matching existing pattern

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 dependencies schema ready for parallel execution logic
• Repository provides all methods needed to track and query phase dependencies
• Ready for plan 14-02
