+# 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

+TDD scaffold for Phase 7.4: Token fingerprinting / token binding.
+
+Covers FGP-01..FGP-04:
+  - FGP-01 test_fgp_match_returns_200: token issued with matching UA/lang →
+    request with same headers returns 200.
+  - FGP-02 test_fgp_mismatch_returns_401: token issued for one UA, request
+    arrives with different UA → 401 "Token fingerprint mismatch".
+  - FGP-03 test_no_fgp_claim_allowed: token manually crafted without "fgp"
+    key → 200 (graceful migration; tokens issued before Phase 7.4 keep
+    working).
+  - FGP-04 test_missing_headers_empty_string_binding: token issued with no
+    UA/lang (defaults to ""), request sent with no User-Agent / Accept-Language
+    headers → 200 (empty-string fingerprint matches).
+
+All four tests are xfail(strict=False) until Wave 1 (Plan 07.4-02) implements
+the fgp claim in services/auth.py and deps/auth.py.
