Phase 07.4 Plan 01: Wave 0 xfail Stubs for Token Fingerprinting (FGP-01..04) Summary

4 xfail test stubs covering JWT token fingerprint (fgp) behaviours added to backend/tests/test_auth_fgp.py using the Phase 7.2/7.3 xfail(strict=False) Wave 0 convention

Performance

• Duration: ~8 min
• Started: 2026-06-06T17:50:00Z
• Completed: 2026-06-06T17:58:00Z
• Tasks: 1
• Files modified: 1

Accomplishments

• Created backend/tests/test_auth_fgp.py with 4 xfail(strict=False) stubs following the Phase 7.2/7.3 Wave 0 convention
• All 4 stubs report XFAIL in pytest tests/test_auth_fgp.py -v — zero failures, zero errors
• Full test suite still runs with 1 pre-existing failure only (test_extract_docx ModuleNotFoundError — unrelated to this plan)
• No production source files modified

Task Commits

1. Task 1: Create test_auth_fgp.py with 4 xfail stubs (FGP-01..FGP-04) - 7833edb (test)

Files Created/Modified

• backend/tests/test_auth_fgp.py — Wave 0 xfail scaffold: make_test_app harness + 4 FGP stubs (FGP-01..04)

Decisions Made

• Stub body is only pytest.xfail("not implemented yet") — no assertion logic; Wave 1 will replace with real assertions
• Copied make_test_app/auth_client/_create_user verbatim from test_auth_deps.py as the plan specified; no /test/admin route added (not needed for FGP tests)
• Did not include import base64, import time, import jwt as _jwt, or from config import settings in the stub file — these imports are needed by the implementation stubs in Wave 1, not the xfail-only Wave 0 stubs

Deviations from Plan

None - plan executed exactly as written.

Issues Encountered

None.

Known Stubs

All 4 test functions are intentional xfail stubs. They will be promoted to full assertions in Plan 07.4-02 (Wave 1) when _compute_fgp, create_access_token signature extension, and the fgp validation block in get_current_user are implemented.

Threat Flags

None — Wave 0 creates test-only stubs with no new security surface.

Self-Check: PASSED

• backend/tests/test_auth_fgp.py exists and contains 4 test functions
• 7833edb commit found in git log
• pytest tests/test_auth_fgp.py -v reports 4 XFAIL, 0 FAILED, 0 ERROR

Next Phase Readiness

• Wave 0 scaffold complete; Plan 07.4-02 (Wave 1) can now implement _compute_fgp in services/auth.py, extend create_access_token, add fgp validation in deps/auth.py, update login/refresh callers in api/auth.py, and promote these 4 stubs to real assertions
