Phase 14 Plan 05: tRPC Procedures for Phase Dependencies and Dispatch Summary

tRPC procedures for phase dependency creation and phase dispatch queue management, exposing PhaseDispatchManager operations via API

Performance

• Duration: 3 min
• Started: 2026-02-02T13:39:00Z
• Completed: 2026-02-02T13:42:00Z
• Tasks: 2
• Files modified: 3

Accomplishments

• Added PhaseDispatchManager to tRPC context with optional pattern
• Added requirePhaseDispatchManager helper function for context validation
• Added createPhaseDependency procedure with phase existence validation
• Added getPhaseDependencies procedure returning dependency IDs
• Added queuePhase, dispatchNextPhase, getPhaseQueueState procedures
• Fixed blocking issue: added 'blocked' status to phases schema enum

Task Commits

Each task was committed atomically:

1. Task 1: Add PhaseDispatchManager to tRPC context - 28622cb (feat)
2. Task 2: Add phase dependency and dispatch procedures - 5e6d507 (feat)

Files Created/Modified

• src/trpc/context.ts - Added PhaseDispatchManager import, added to TRPCContext and CreateContextOptions, wired through createContext
• src/trpc/router.ts - Added PhaseDispatchManager import, requirePhaseDispatchManager helper, 5 new procedures (createPhaseDependency, getPhaseDependencies, queuePhase, dispatchNextPhase, getPhaseQueueState)
• src/db/schema.ts - Added 'blocked' to phases status enum (blocking fix)

Decisions Made

• PhaseDispatchManager optional in context following agentManager/dispatchManager pattern
• createPhaseDependency validates both phases exist before creating dependency
• getPhaseDependencies returns wrapper object { dependencies: string[] } for API consistency
• Phase dispatch procedures added in new "Phase Dispatch Procedures" section
• Dependency procedures added under existing "Phase Procedures" section

Deviations from Plan

Auto-fixed Issues

1. [Rule 3 - Blocking] Fixed phases schema missing 'blocked' status

• Found during: Task 1 (type-checking after context changes)
• Issue: PhaseDispatchManager.blockPhase() tries to set status 'blocked' but phases schema only allowed 'pending', 'in_progress', 'completed'
• Fix: Added 'blocked' to phases status enum in schema.ts, updated updatePhase procedure to accept 'blocked'
• Files modified: src/db/schema.ts, src/trpc/router.ts
• Verification: npx tsc --noEmit passes
• Committed in: 28622cb (Task 1 commit)

---

Total deviations: 1 auto-fixed (1 blocking) Impact on plan: Essential fix to allow phase blocking functionality. Pre-existing bug from plan 14-04.

Issues Encountered

None.

User Setup Required

None - no external service configuration required.

Next Phase Readiness

• Phase dependency and dispatch procedures available via tRPC API
• Full API surface for parallel phase execution management
• Ready for plan 14-06
