Phase 4 Plan 06: Admin Audit Log API + Celery Daily Export Summary

One-liner: Admin-only paginated/filtered audit log viewer with CSV streaming export (ADMIN-06) and midnight-UTC Celery beat task uploading daily CSVs to MinIO audit-logs bucket (D-17).

Tasks Completed

Task	Name	Commit	Files
1	Admin audit log viewer + CSV export	364447d	backend/api/audit.py, backend/main.py
2	Celery daily export task + beat schedule	f89f787	backend/tasks/audit_tasks.py, backend/celery_app.py

What Was Built

Task 1: backend/api/audit.py

Two admin-only endpoints protected by Depends(get_current_admin):

• GET /api/admin/audit-log — paginated (page/per_page), filtered (start, end, user_id, event_type). Returns {items, total, page, per_page}. Runs a separate COUNT query for total using the same filters.
• GET /api/admin/audit-log/export — same filter params, no pagination; streams CSV with Content-Disposition: attachment; filename=audit-export.csv.

The _audit_to_dict() helper is the single source of truth for the safe field set: id, event_type, user_id, actor_id, resource_id, ip_address, metadata_, created_at. The dict literal contains no filename, extracted_text, password_hash, or credentials_enc keys. Both the JSON and CSV paths use this same helper.

Task 2: backend/tasks/audit_tasks.py + celery_app.py

• audit_log_daily_export Celery task: sync entry point → asyncio.run(_run_daily_export()).
• _run_daily_export(): queries yesterday's AuditLog rows (UTC midnight to midnight), writes CSV via csv.DictWriter, uploads to MinIO via put_object_raw(bucket="audit-logs", key="audit-logs/YYYY-MM-DD.csv", ...). Wraps everything in try/except — returns {"exported": 0, "error": str(e)} on failure.
• All imports deferred inside _run_daily_export() body (same circular-import-prevention pattern as document_tasks._run).
• celery_app.py: _crontab aliased import, beat entry "audit-log-daily-export" at _crontab(hour=0, minute=0), task route "tasks.audit_tasks.*": {"queue": "documents"}.

Deviations from Plan

None — plan executed exactly as written.

Security Invariants Verified

Threat ID	Check	Result
T-04-06-01	Depends(get_current_admin) on both endpoints (grep: 2 occurrences at lines 94, 129)	PASS
T-04-06-02	_audit_to_dict() dict literal contains no forbidden keys (grep: filename/extracted_text only in comments)	PASS
T-04-06-03	CSV export uses same _audit_to_dict() helper as JSON viewer	PASS
T-04-06-04	put_object_raw uses bucket="audit-logs" (not documents bucket)	PASS

Test Results

tests/test_audit.py: 4 xfailed (stub tests from Wave 0 — plan 04-06 implements the API,
  detailed integration tests will be written in the full TDD pass)
Full suite: 1 failed (test_extractor.py::test_extract_docx — pre-existing missing module,
  out of scope), 130 passed, 7 skipped, 35 xfailed

Pre-existing failures (not caused by this plan):

• test_extractor.py::test_extract_docx — missing python-docx module in local env
• test_documents.py::test_content_stream_200 — intentional TDD RED from plan 04-05 (commit 8e6cb6e)

Known Stubs

None — both endpoints are fully implemented and wired.

Threat Flags

None — no new network endpoints or trust boundaries beyond those documented in the plan's threat model.
