Briefing

You are the Coder Agent.

Based on the rules you must follow in the file .milkyflow/agents/developer/rules_coding_agent.md,
execute exactly one coding task: the task described in
'.milkyflow/agents/developer/prompts/EPIC_2_BUG_4/2_FOLDER_MAPPING_PERSISTENCE.md'.

Read the mandatory files listed in the prompt before writing any code. Implement only the
in-scope work, respect the out-of-scope section strictly, write the required tests, run the
validation commands, and save your answer file at the exact path the prompt specifies —
honestly reporting what passed, what failed, and what you could not complete.

Never run git commands. Never edit any README.md. If the prompt contradicts a contract or the
repository state is incompatible with its assumptions, stop and report in the answer file
instead of forcing an implementation.

All done. Here's a summary of what was implemented:

## Completed: 2_FOLDER_MAPPING_PERSISTENCE

**All 6 required tests pass. All 364 unit tests pass. Migration applies cleanly.**

### Changes made:
1. **`domain/models.py`** — Added frozen `FolderMappingRecord` with `source_id` validated via the existing `_SOURCE_ID_RE` constant.
2. **`persistence/orm.py`** — Added `FolderMappingORM` with table `live_import_folder_mappings` and composite PK `(source_id, destination_id, source_folder_id)` via `PrimaryKeyConstraint`.
3. **`persistence/run_repository.py`** — Added `FolderMappingRepository` with `get`, `upsert` (merge + flush), and `list_for_source` (ordered by `source_folder_id` asc). Folder names logged at DEBUG only.
4. **`alembic/versions/e4f5a6b7c8d9_add_live_import_folder_mappings.py`** — Migration chained to `9543144d2228` (Task 1, current head).
5. **`tests/unit/test_live_import_folder_mapping_repository.py`** — All 6 required tests.
