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_4/1_SOURCE_PC_API_CONFIG.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 I have enough context. Let me implement all the changes:
[tool] view {'path': '/home/oem/Documents/Sandbox/Kody/Projects/Backupper/src/backup_cockpit/live_import/domain/errors.py'}
The prompt says to import `CredentialUnavailableError` from `live_import.domain.errors`, but the errors file only has `DestinationCredentialUnavailableError`. I need to add a `CredentialUnavailableError` class (as a generic one for the source side). Let me now implement all the changes in order:

**1. Add `CredentialUnavailableError` to errors.py**
[tool] edit {'path': '/home/oem/Documents/Sandbox/Kody/Projects/Backupper/src/backup_cockpit/live_import/domain/errors.py', 'old_str
**2. Add `SourcePCCredentialProvider` to provider.py**
[tool] edit {'new_str': 'from backup_cockpit.live_import.domain.errors import (\n CredentialUnavailableError,\n DestinationCredentia
[tool] bash {'command': 'cat >> /home/oem/Documents/Sandbox/Kody/Projects/Backupper/src/backup_cockpit/live_import/credentials/provi
**3. Update `RawCaptureSourceConfig` domain model**
[tool] edit {'new_str': ' is_critical: bool = False\n """Whether this source is designated as deadline-critical by the operator."""\
Now add the validators for the new fields. Let me add them after the existing `_validate_connect_timeout` validator:
[tool] edit {'new_str': ' @field_validator("connect_timeout_seconds")\n @classmethod\n def _validate_connect_timeout(cls, v: int) ->
**4. Update ORM model**
… Let me start by reading the rules file and the prompt file.
[tool] edit {'new_str': ' is_critical = mapped_column(Boolean, nullable=False, default=False)\n pc_base_url = mapped_column(String, 
**5. Update Repository to map new fields**
… Let me start by reading the rules file and the prompt file.
[tool] edit {'new_str': ' @staticmethod\n def _to_orm(config: RawCaptureSourceConfig) -> RawCaptureSourceORM:\n return RawCaptureSou
… Let me start by reading the rules file and the prompt file.
[tool] edit {'new_str': ' @staticmethod\n def _to_domain(orm: RawCaptureSourceORM) -> RawCaptureSourceConfig:\n return RawCaptureSou
**6. Update CLI commands for PC flags**
… Let me start by reading the rules file and the prompt file.
[tool] view {'path': '/home/oem/Documents/Sandbox/Kody/Projects/Backupper/src/backup_cockpit/raw_capture/cli/commands.py', 'view_ran
… Let me start by reading the rules file and the prompt file.
[tool] edit {'new_str': 'def _cmd_source_register(args: argparse.Namespace) -> None:\n import getpass # noqa: PLC0415 (intentional l
Now update `_cmd_source_update` to add PC flags. Let me first view the current update function:
… Let me start by reading the rules file and the prompt file.
[tool] view {'path': '/home/oem/Documents/Sandbox/Kody/Projects/Backupper/src/backup_cockpit/raw_capture/cli/commands.py', 'view_ran

… Let me start by reading the rules file and the prompt file.
[tool] edit {'new_str': ' if args.is_critical is not None:\n updates["is_critical"] = args.is_critical\n\n if pc_url is not None:\n 
Now I need to find the argparse setup for `source register` and `source update` to add the new flags. Let me look further down in commands.py:
… Let me start by reading the rules file and the prompt file.
[tool] bash {'command': 'grep -n "add_argument\\|source_register\\|source_update\\|def _build\\|subparsers\\|add_parser" /home/oem/D

[tool] edit {'new_str': ' reg.add_argument(\n "--critical",\n action="store_true",\n default=False,\n dest="critical",\n help="Mark 
**7. Create Alembic migration**

The current head is `d61ba9907325`. I need a new 12-hex-char revision ID:
… Let me start by reading the rules file and the prompt file.
[tool] bash {'command': 'python3 -c "import secrets; print(secrets.token_hex(6))"', 'description': 'Generate 12-hex revision ID'}
… Let me start by reading the rules file and the prompt file.
[tool] create {'path': '/home/oem/Documents/Sandbox/Kody/Projects/Backupper/alembic/versions/9543144d2228_add_source_pc_api_fields.py'
**8. Create the unit test file**
… Let me start by reading the rules file and the prompt file.
[tool] view {'path': '/home/oem/Documents/Sandbox/Kody/Projects/Backupper/tests/unit/test_live_import_credential_provider.py', 'view
Now I'll look for the CLI test patterns:
… Let me start by reading the rules file and the prompt file.
[tool] bash {'command': 'ls /home/oem/Documents/Sandbox/Kody/Projects/Backupper/tests/unit/ | grep -i raw', 'description': 'List raw
… Let me start by reading the rules file and the prompt file.
[tool] bash {'command': 'ls /home/oem/Documents/Sandbox/Kody/Projects/Backupper/tests/unit/', 'description': 'List all unit tests'}
[tool] view {'path': '/home/oem/Documents/Sandbox/Kody/Projects/Backupper/tests/unit/test_cli_commands.py', 'view_range': [1, 80]}
Now I have enough context to create the test file:
… Let me start by reading the rules file and the prompt file.
[tool] create {'file_text': '"""Unit tests for RawCaptureSourceConfig PC-API fields and SourcePCCredentialProvider.\n\nAll keyring int
Now let me check the `commands.py` `_cmd_source_register` function — some imports it uses might not exist at module level. The CLI test uses patch paths like `backup_cockpit.raw_capture.cli.commands.SourcePCCredentialProvider`. Let me check what the function currently imports:
… Let me start by reading the rules file and the prompt file.
[tool] view {'path': '/home/oem/Documents/Sandbox/Kody/Projects/Backupper/src/backup_cockpit/raw_capture/cli/commands.py', 'view_ran
The imports are local inside the function, which means my patch paths `backup_cockpit.raw_capture.cli.commands.SourcePCCredentialProvider` won't work — the lazy import means these names are local to the function. The test I wrote uses incorrect patch paths. Let me fix the test to patch at the module level of the provider:
… Let me start by reading the rules file and the prompt file.
[tool] view {'path': '/home/oem/Documents/Sandbox/Kody/Projects/Backupper/tests/unit/test_raw_capture_source_pc_config.py', 'view_ra
I need to redesign the CLI test. Since the imports in `_cmd_source_register` are local (lazy), I need to patch at the source module paths (not the CLI commands module). Let me rewrite the CLI portion of the test file:
… Let me start by reading the rules file and the prompt file.
[tool] edit {'new_str': 'def test_cli_register_with_pc_flags_sets_credential_key(\n monkeypatch: pytest.MonkeyPatch,\n) -> None:\n "
Now let's run the new tests:
… Let me start by reading the rules file and the prompt file.
[tool] bash {'command': 'cd /home/oem/Documents/Sandbox/Kody/Projects/Backupper && source .venv/bin/activate && python -m pytest tes
… Let me start by reading the rules file and the prompt file.
[tool] bash {'command': 'grep -A 30 "FAILURES" /tmp/1786245188609-copilot-tool-output-302494-d639a849-8932-4bb2-af93-ce4e72fe5d08.tx
… Let me start by reading the rules file and the prompt file.

I see two issues:
1. `source_id` is positional in the actual register parser but the test is parsing it as a positional — but argparse says `--source-id` is required. Let me check the actual `register` arg structure:
… Let me start by reading the rules file and the prompt file.
[tool] view {'path': '/home/oem/Documents/Sandbox/Kody/Projects/Backupper/src/backup_cockpit/raw_capture/cli/commands.py', 'view_ran
The register command uses `--source-id` not a positional argument. Also, the error output goes to stderr (print vs stderr). Let me fix the tests:
… Let me start by reading the rules file and the prompt file.
[tool] edit {'new_str': 'def test_cli_register_with_pc_flags_sets_credential_key(\n monkeypatch: pytest.MonkeyPatch,\n) -> None:\n "
… Let me start by reading the rules file and the prompt file.
[tool] bash {'command': 'cd /home/oem/Documents/Sandbox/Kody/Projects/Backupper && source .venv/bin/activate && python -m pytest tes
All 12 tests pass. Now run the full validation suite:
… Let me start by reading the rules file and the prompt file.
[tool] bash {'command': 'cd /home/oem/Documents/Sandbox/Kody/Projects/Backupper && source .venv/bin/activate && python -m pytest tes
[tool] bash {'command': 'cd /home/oem/Documents/Sandbox/Kody/Projects/Backupper && source .venv/bin/activate && python -m pytest tes

… Let me start by reading the rules file and the prompt file.
[tool] bash {'command': 'cd /home/oem/Documents/Sandbox/Kody/Projects/Backupper && source .venv/bin/activate && python - <<\'EOF\'\n
All validations pass. Now let me get the timestamp and create the answer file and history entry:

… Hmm, no output. Let me just check the full output.
[tool] bash {'command': 'cd /home/oem/Documents/Sandbox/Kody/Projects/Backupper && source .venv/bin/activate && python -m pytest tes
All 358 tests pass (1 deprecation warning, no failures). Now append the history row:

[tool] bash {'command': 'cd /home/oem/Documents/Sandbox/Kody/Projects/Backupper && TS=$(date -u +%Y-%m-%dT%H:%M:%SZ) && HISTORY=".mi
