Phase 5 Plan 1: Discussion Service Summary

Discussion service with 9 async CRUD operations for discussions, rounds, and messages using selectinload eager loading

Performance

• Duration: 2 min
• Started: 2026-01-16T19:24:14Z
• Completed: 2026-01-16T19:26:56Z
• Tasks: 2
• Files modified: 2

Accomplishments

• Created discussion service following established service layer pattern
• Implemented 5 discussion operations: create, get (with eager loading), get_active, list, complete
• Added 4 round/message operations: create_round, get_current_round, create_message, get_round_messages
• Used selectinload for eager loading rounds→messages to avoid N+1 queries

Task Commits

Each task was committed atomically:

1. Task 1: Create discussion service with CRUD operations - 3258c3a (feat)
2. Task 2: Add round and message operations - baf02bb (feat)

Files Created/Modified

• src/moai/core/services/discussion.py - Discussion, Round, Message CRUD operations (9 async functions)
• src/moai/core/services/__init__.py - Updated exports

Decisions Made

• Used selectinload for eager loading rounds→messages→consensus to prevent N+1 queries
• get_discussion includes consensus in eager loading for future phase 6
• get_current_round orders by round_number desc with limit 1 for efficiency

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None

Next Phase Readiness

• Discussion service ready for /open and /discuss command handlers
• Round/message operations available for multi-model discussion flow
• Ready for 05-02-PLAN.md (open mode handler)
