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_US_1/2_PERSISTENCE_LAYER.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.

Now let me also check the existing unit tests for patterns:

Now I have all the context I need. Let me implement everything:

● Create directories (shell)
  │ mkdir -p
  │ /home/oem/Documents/Sandbox/Kody/Projects/Backupper/src/backup_cockpit/live_import/credentials
  │ mkdir -p /home/oem/Documents/Sandbox/Kody/Projects/Backupper/.milkyflow/agents/developer/answe
  │ rs/EPIC_2_US_1
  │ ls /home/oem/Documents/Sandbox/Kody/Projects/Backupper/src/backup_cockpit/live_import/persiste…
  └ 3 lines…

● Create provider.py +163
  └ src/backup_cockpit/live_import/credentials/provider.py

● Create __init__.py +1
  └ src/backup_cockpit/live_import/credentials/__init__.py

● Create orm.py +39
  └ src/backup_cockpit/live_import/persistence/orm.py

● Create repository.py +112
  └ src/backup_cockpit/live_import/persistence/repository.py

Now create the Alembic migration:

● Create b2c3d4e5f6a7_add_live_import_destinations.py +41
  └ alembic/versions/b2c3d4e5f6a7_add_live_import_destinations.py

Now create the unit tests:

● Create test_live_import_repository.py +146
  └ tests/unit/test_live_import_repository.py

● Create test_live_import_credential_provider.py +127
  └ tests/unit/test_live_import_credential_provider.py

● Create test_live_import_persistence_integration.py +128
  └ tests/integration/test_live_import_persistence_integration.py

Now run the validation commands:

● Run alembic upgrade head (shell)
  │ PATH=".venv/bin:$PATH" .venv/bin/alembic upgrade head 2>&1
  └ 4 lines…

● Run all new tests (shell)
  │ PATH=".venv/bin:$PATH" .venv/bin/pytest tests/unit/test_live_import_repository.py
  │ tests/unit/test_live_import_credential_provider.py
  │ tests/integration/test_live_import_persistence_integration.py -v 2>&1
  └ 103 lines…

Fix: `_make_config` duplicates the `display_name` kwarg. I need to not pass the default when it's overridden:

● Edit test_live_import_repository.py +12 -12
  └ tests/unit/test_live_import_repository.py

● Edit test_live_import_persistence_integration.py +12 -12
  └ tests/integration/test_live_import_persistence_integration.py

● Rerun tests (shell)
  │ PATH=".venv/bin:$PATH" .venv/bin/pytest tests/unit/test_live_import_repository.py
  │ tests/unit/test_live_import_credential_provider.py
  │ tests/integration/test_live_import_persistence_integration.py -v 2>&1
  └ 21 lines…

All 20 tests pass. Now run ruff, mypy, and bandit:

● Run ruff, mypy, bandit (shell)
  │ .venv/bin/ruff check src/backup_cockpit/live_import/persistence/
  │ src/backup_cockpit/live_import/credentials/ 2>&1
  │ .venv/bin/mypy src/backup_cockpit/live_import/persistence/
  │ src/backup_cockpit/live_import/credentials/ 2>&1
  │ .venv/bin/bandit -r src/backup_cockpit/live_import/persistence/ …
  └ 77 lines…

Fix ruff issue (import sort) and mypy issues (Column type annotations):

● Edit provider.py +3 -1
  └ src/backup_cockpit/live_import/credentials/provider.py

Now fix the mypy issues in `repository.py`. The raw_capture ORM uses `mapped_column` which gives proper types; our ORM uses `Column` which doesn't infer correctly. Let me look at how raw_capture does `_to_domain`:

● Check raw_capture _to_domain pattern (shell)
  │ grep -n "_to_domain\|mapped_column\|Column"
  │ /tmp/1785951555305-copilot-tool-output-43382-4ca2f7f6-d4e0-417f-8af5-89289448f89c.txt | head -40
  └ 40 lines…

I need to switch the ORM to use `mapped_column` for proper type inference:

● Edit orm.py +11 -11
  └ src/backup_cockpit/live_import/persistence/orm.py

● Re-run ruff and mypy (shell)
  │ .venv/bin/ruff check src/backup_cockpit/live_import/persistence/
  │ src/backup_cockpit/live_import/credentials/ 2>&1 && .venv/bin/mypy
  │ src/backup_cockpit/live_import/persistence/ src/backup_cockpit/live_import/credentials/ 2>&1
  └ 3 lines…

All clean. Run the full test suite one more time to confirm everything still passes:

● Final test run (shell)
  │ PATH=".venv/bin:$PATH" .venv/bin/pytest tests/unit/test_live_import_repository.py
  │ tests/unit/test_live_import_credential_provider.py
  │ tests/integration/test_live_import_persistence_integration.py -v 2>&1 | tail -20
  └ 21 lines…

All 20 tests pass. Now write the answer file and history:

● Create 2_PERSISTENCE_LAYER.md +140
  └ .milkyflow/agents/developer/answers/EPIC_2_US_1/2_PERSISTENCE_LAYER.md

● Append to history.md (shell)
  │ HIST="/home/oem/Documents/Sandbox/Kody/Projects/Backupper/.milkyflow/agents/history.md"
  │ if [ ! -f "$HIST" ]; then
  │ echo "| Timestamp | Agent | Scenario | Details |" > "$HIST"
  │ echo "|-----------|-------|----------|---------|" >> "$HIST"
  │ fi…
  └ 5 lines…

All done. Here's a summary:

## ✅ Task Complete — 2_PERSISTENCE_LAYER

**20/20 tests passed. All validators clean.**

### What was implemented
- **`credentials/provider.py`** — `DestinationCredentialProvider` with namespace `backup-cockpit-live-import`; mirrors raw_capture pattern; secrets never leak into errors
- **`persistence/orm.py`** — `DestinationORM` (9 columns, **no password column**), using `mapped_column` for mypy compatibility
- **`persistence/repository.py`** — `DestinationRepository` with upsert via `Session.merge()`, `get/get_or_raise/list_all/remove`
- **Alembic migration** `b2c3d4e5f6a7` (down_revision: `a1b2c3d4e5f6`) — creates/drops `live_import_destinations`

### Validation outcomes
| Command | Result |
|---------|--------|
| `alembic upgrade head` | ✅ PASS |
| `pytest` (20 tests) | ✅ PASS |
| `ruff check` | ✅ PASS (1 import-sort fixed) |
| `mypy` | ✅ PASS (switched `Column` → `mapped_column`) |
| `bandit` | ✅ PASS |
