## Code Review: PASS - Merge Conflicts Resolved
### ✅ Previous Issue Fixed
The worker resolved the merge conflicts in `db/schema.rb`. The schema now cleanly includes both:
- `proposals` table with proper indexes
- `solid_queue_*` tables (from main branch)
- Foreign keys for both
No conflict markers remain.
### ✅ All Acceptance Criteria Met
1. **Proposals table exists with all fields** ✓
- title, proposal_type, reasoning, confidence, priority, status
- JSON metadata for evidence_links
- Optional ticket_id, agent_id foreign keys
- Proper indexes on queryable fields
2. **Metadata stored as JSON with evidence_links** ✓
- `metadata["evidence_links"]` accessor method
- `add_evidence_link` method for adding links
- Supports type (ticket/memory/code_file), id, path, description
3. **API endpoints work** ✓
- POST /api/v1/proposals - Create
- GET /api/v1/proposals - List with filters
- GET /api/v1/proposals/:id - Show
- POST /api/v1/proposals/:id/approve - Approve
- POST /api/v1/proposals/:id/reject - Reject
- POST /api/v1/proposals/approve_batch - Bulk approve
4. **Avo admin interface** ✓
- Resource with filters (status, type, priority)
- Show page with metadata display
- Approve/Reject actions
- Batch approve action
5. **Searchable and filterable** ✓
- Scopes: pending, approved, rejected, executed
- Scopes: by_priority, by_confidence, by_type, by_agent
- Status predicate methods (pending?, approved?, etc.)
### Code Quality
**Model (`app/models/proposal.rb`):**
- Comprehensive validations with inclusion constraints
- Clear status workflow (pending → approved/rejected → executed)
- Rejection feedback stored in AgentMemory for learning
- Evidence link helpers
**Controller (`app/controllers/api/v1/proposals_controller.rb`):**
- Proper filtering, sorting, pagination
- Error handling with meaningful messages
- Batch approve functionality
**Avo Resources:**
- Clean admin interface with filters
- Actions for approve/reject/batch
### Test Results
- **Proposal model tests: 27 examples, 0 failures** ✓
### Note on Other Test Failures
Some tests in the broader suite fail due to a pre-existing issue: the tickets factory still references `acceptance_criteria` column that was removed in PR #74. This is **not caused by this PR** and affects the entire codebase.
### Recommendation: PASS
The merge conflicts have been resolved, the proposal system is well-implemented with comprehensive tests, and all acceptance criteria are met. The pre-existing factory issue is a separate concern.
