# BE-PR-001: Propose → Proposal Rename Impact Checklist

## Summary
Unified all backend Python-level naming from `Propose` to `Proposal`. DB table and column names kept unchanged for backward compatibility (no migration needed).

## Files Changed

### New Files
- `app/models/proposal.py` — Canonical model: `Proposal`, `ProposalStatus`
- `app/api/routers/proposals.py` — Canonical router at `/projects/{id}/proposals`

### Modified Files
- `app/models/propose.py` — Now a backward-compat shim re-exporting from `proposal.py`
- `app/api/routers/proposes.py` — Now a backward-compat shim delegating to `proposals.py` (legacy `/proposes` URL still works)
- `app/schemas/schemas.py` — Renamed: `ProposalStatusEnum`, `ProposalBase`, `ProposalCreate`, `ProposalUpdate`, `ProposalResponse` (old names kept as aliases)
- `app/main.py` — Registers both `proposals_router` (canonical) and `proposes_router` (legacy compat)
- `app/init_wizard.py` — Updated comments to say "Proposal" (permission names `propose.*` kept for DB compat)
- `tests/test_propose.py` — Updated all tests to use `/proposals` URL; added legacy endpoint compat tests

## What Was Kept for Backward Compatibility
| Item | Kept As-Is | Reason |
|------|-----------|--------|
| DB table name | `proposes` | Avoid DB migration |
| DB column | `propose_code` | Avoid DB migration |
| Permission names | `propose.accept`, `propose.reject`, `propose.reopen` | Already stored in DB |
| Legacy API path | `/projects/{id}/proposes/*` | Client compat |
| Python aliases | `Propose`, `ProposeStatus`, `ProposeCreate`, etc. | Import compat |

## API Endpoints
- **Canonical:** `/projects/{project_id}/proposals` (new)
- **Legacy:** `/projects/{project_id}/proposes` (still works, delegates to canonical)
