# Dependency graph
requires:
  - phase: 06.1-close-v1-audit-gaps
    provides: "test_shares.py, test_audit.py, test_documents.py with existing passing tests"
provides:
  - "11 named xfail stubs (3 in test_shares.py, 3 in test_documents.py, 5 in test_audit.py)"
  - "Nyquist contract: every Wave 1 and Wave 2 gap has a test function before implementation begins"
affects:
  - 06.2-02 (SHARE-03 — must promote test_share_create_with_permission, test_share_patch_permission, test_share_patch_idor)
  - 06.2-03 (cloud-delete — must promote test_delete_cloud_document_propagates, test_delete_cloud_document_failure, test_delete_cloud_remove_only)
  - 06.2-04 (ADMIN-06 — must promote all 5 test_audit_log_* and test_daily_* stubs)

# Phase 06.2 Plan 01: Wave 0 Nyquist Xfail Stubs Summary

**11 named xfail stubs planted across test_shares.py, test_documents.py, and test_audit.py — establishing the Nyquist contract for all SHARE-03, cloud-delete, and ADMIN-06 gaps before Wave 1/2 implementation begins**

## Performance

- **Duration:** ~8 min
- **Started:** 2026-05-31T09:50:00Z
- **Completed:** 2026-05-31T09:58:12Z
- **Tasks:** 3
- **Files modified:** 3

## Accomplishments

- Added 3 xfail stubs to test_shares.py covering SHARE-03 permission field (POST), PATCH endpoint, and IDOR protection
- Added 3 xfail stubs to test_documents.py covering cloud document delete propagation, structured failure response, and remove_only path
- Added 5 xfail stubs to test_audit.py covering user_handle enrichment, handle-based filtering (known + unknown), daily exports listing, and daily export download
- All 11 stubs report as XFAIL (not ERROR, not FAILED); full 3-file suite exits 0: 35 passed, 15 xfailed

## Task Commits

Each task was committed atomically:

1. **Task 1: Add xfail stubs to test_shares.py (SHARE-03)** - `ecdeffb` (test)
2. **Task 2: Add xfail stubs to test_documents.py (cloud-delete)** - `bbf5355` (test)
3. **Task 3: Add xfail stubs to test_audit.py (ADMIN-06 gaps)** - `7271eeb` (test)

## Files Created/Modified

- `backend/tests/test_shares.py` - Appended 3 xfail stubs (test_share_create_with_permission, test_share_patch_permission, test_share_patch_idor)
- `backend/tests/test_documents.py` - Appended 3 xfail stubs (test_delete_cloud_document_propagates, test_delete_cloud_document_failure, test_delete_cloud_remove_only)
- `backend/tests/test_audit.py` - Appended 5 xfail stubs (test_audit_log_includes_user_handle, test_audit_log_filter_by_handle, test_audit_log_filter_unknown_handle, test_daily_exports_list, test_daily_export_download)

## Decisions Made

- Used inline `pytest.xfail("Phase 6.2 — not implemented yet")` as first statement rather than `@pytest.mark.xfail` decorator — matches existing inline pattern in test_documents.py and Wave 0 stubs in prior phases. Inline calls have `strict=False` by default (no CI breakage on unexpected pass).
- All stubs include the full fixture signature required by Wave 1/2 implementations (async_client, auth_user, second_auth_user, db_session, admin_user) so Wave 1/2 executors can promote without changing the function signature.

## Deviations from Plan

None - plan executed exactly as written.

## Issues Encountered

None.

## User Setup Required

None - no external service configuration required.

## Next Phase Readiness

- Wave 0 Nyquist contract complete: all 11 test function names exist in their target files
- Wave 1 (Plans 06.2-02 and 06.2-03) can promote stubs by implementing them in place without any rename
- Wave 2 (Plan 06.2-04) can promote all 5 audit stubs once ADMIN-06 enrichment and daily exports are implemented
- Pre-existing test suite health: 35 passed, 15 xfailed, exits 0 — no regressions introduced

## Self-Check: PASSED

Verified:
- `backend/tests/test_shares.py` — contains 3 new xfail stubs (ecdeffb)
- `backend/tests/test_documents.py` — contains 3 new xfail stubs (bbf5355)
- `backend/tests/test_audit.py` — contains 5 new xfail stubs (7271eeb)
- All commits confirmed in git log
- `pytest tests/test_shares.py tests/test_audit.py tests/test_documents.py -x -q` exits 0: 35 passed, 15 xfailed
