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_3/2_BOOTSTRAP_USE_CHILD_FOLDER.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 prerequisites are confirmed. Now let me check the integration test file and errors import:

The unit tests for bootstrap are failing because they still mock `list_root_folders`/`create_root_folder`. Let me check them:

The existing unit tests mock `list_root_folders` and `create_root_folder` — but now the bootstrap code calls `list_child_folders`, `create_child_folder`, and `_list_accessible_folder_ids`. I need to update the unit test helper to mock the new methods instead.

Task complete. Here's a summary of what was done:

## Summary

**`src/backup_cockpit/live_import/run/bootstrap.py`** — 3 changes:
1. Added `DestinationWriteError` import
2. Inserted `backup_parent_id` resolution block after step b (raises `DestinationWriteError` if no accessible folders)
3. Replaced all 4 old client calls: `list_root_folders` → `list_child_folders(token, backup_parent_id)` and `create_root_folder` → `create_child_folder(token, stable_name, backup_parent_id)`

**`tests/unit/test_live_import_bootstrap.py`** — updated `_bootstrap_with_mocks` helper to mock the new methods (unavoidable, flagged in answer)

**`tests/integration/test_live_import_run_integration.py`** — added `test_run_creates_child_folder_not_root`

**Validation:**
- `python -m pytest tests/unit/ -v` → **344 passed** ✅
- `python -m pytest tests/ -v -m "not integration"` → **396 passed** ✅
