Phase 13 Plan 09: Move and Delete — Validation, Reconciliation, and Audit Summary

One-liner: Move descendant-safety, stale guard, and reconcile-before-return; delete folder disclosure and metadata-only audit rows for both move and delete.

Tasks Completed

Task	Name	Commit	Key Files
1 (RED)	Add failing tests for move stale-guard, descendant safety, reconciliation, and delete/audit	af7d45f	test_cloud_mutations.py
1/2 (GREEN)	Implement move/delete with stale guards, reconciliation, disclosure, and audit	508d276	api/cloud/operations.py, test_cloud_audit.py

What Was Built

Task 1: Move — Descendant Safety, Stale Guard, Centralized Reconciliation

_is_descendant_destination() helper in backend/api/cloud/operations.py:

New async helper that walks the ancestor chain of a proposed destination through cloud_items metadata:

while current_ref is not None:
    if current_ref == source_item_id:
        return True  # destination is a descendant of source
    # look up parent of current_ref via CloudItem.parent_ref
    current_ref = parent_item.parent_ref if parent_item else None

• D-09: Backend independently rejects descendant destinations without provider involvement
• Protection against cycles via a visited-set guard

move_cloud_item in backend/api/cloud/operations.py:

Comprehensive move implementation:

1. D-08 Cross-connection rejection — before any adapter call (unchanged)
2. D-09 Self-destination rejection — before any adapter call (unchanged)
3. D-09 Descendant destination rejection — metadata-only ancestor-chain walk before adapter call
4. Pre-fetch item metadata — resolves source_parent_ref, item_kind, item_name before adapter
5. D-07 Stale guard — stale adapter result marks source folder non-fresh, returns typed stale body
6. Reconcile-before-return on success:
   • upsert_cloud_item with parent_ref=resolved_dest_parent_ref
   • update_folder_state for source folder (item removed)
   • update_folder_state for destination folder (item added)
   • write_audit_log cloud.item_moved with metadata-only payload
   • session.commit()

Task 2: Delete — Folder Disclosure and Metadata-Only Audit

delete_cloud_item in backend/api/cloud/operations.py:

1. Pre-fetch item metadata — resolves item_kind and item_parent_ref before adapter call
2. D-10 Folder disclosure — response includes is_folder and item_kind for frontend to display stronger folder-delete warning
3. Reconcile-before-return on success:
   • update_folder_state for parent folder (item removed)
   • write_audit_log cloud.item_deleted with delete_kind, item_kind, provider_item_id
   • session.commit()
4. D-11 Trash vs permanent — delete_kind in audit metadata and response reason distinguish trashed vs permanent delete

Success response now includes:

{
    "kind": "deleted",
    "reason": "trashed",           # or "permanent"
    "provider_item_id": "...",
    "item_kind": "folder",         # D-10 disclosure
    "is_folder": True,             # D-10 stronger confirmation
}

Test Suite Results

766 passed, 17 skipped, 4 deselected, 10 xfailed, 55 warnings

Previous baseline (Plan 08): 755 passed, 17 skipped, 4 deselected, 12 xfailed

• 11 new tests added in test_cloud_mutations.py (all pass)
• 2 xfail markers promoted in test_cloud_audit.py (move + delete audit tests now pass)
• Net: +11 passing, -2 xfailed = 766 total passing

Deviations from Plan

Auto-fixed Issues

1. [Rule 1 - Bug] Audit tests in test_cloud_audit.py needed mock adapters

• Found during: Task 2 (GREEN verification)
• Issue: test_move_success_writes_audit_row and test_delete_success_writes_audit_row were promoted from xfail but used real connections without mock adapters — provider calls returned 503 which was not in the accepted status codes
• Fix: Added explicit mock adapters with build_mutable_cloud_adapter patch so tests exercise the audit write path deterministically
• Files modified: backend/tests/test_cloud_audit.py
• Commit: 508d276 (included in GREEN commit)

Known Stubs

None. Move and delete reconciliation are fully functional, including stale guards, descendant safety, and metadata-only audit rows.

Threat Flags

No new security surfaces introduced. T-13-27, T-13-28, T-13-29 are mitigated:

• T-13-27 (move destinations): Descendant-chain walk + self-check + cross-connection check enforce D-08 and D-09 before and independently of provider submission.
• T-13-28 (stale move safety): Stale guard stops move, refreshes source folder, requires retry — never forcing a stale move.
• T-13-29 (delete disclosure and audit): Typed delete results carry is_folder/item_kind; audit tests verify no token or byte appears in metadata_.

Self-Check: PASSED

• FOUND: backend/api/cloud/operations.py with _is_descendant_destination, move stale guard, move/delete reconcile-before-return, and move/delete audit writes
• FOUND: backend/tests/test_cloud_mutations.py with 11 new behavioral tests
• FOUND: backend/tests/test_cloud_audit.py with promoted move/delete xfail markers and mock adapters
• FOUND commit: af7d45f (RED tests)
• FOUND commit: 508d276 (GREEN implementation)
• Full suite: 766 passed, 17 skipped, 4 deselected, 10 xfailed
