Quick TA re-review of T20 test additions only. The code fix was already approved. Verify the 6 new test scenarios correctly cover the FAULT-012 fix and the mock fix. Run phpunit to confirm all tests pass. Give APPROVE/REVISE verdict.

I'll start by examining the test files and running the tests in parallel.

Let me find the correct phpunit path and verify the source code fix.

The 7 errors are all in pre-existing test files (`RateLimitRepositoryTest` and `RateLimiterTest`) — unrelated to our review. Let me isolate only the `RateLimiterModuleTest`:

All 11 tests pass. Let me check what the "PHPUnit Notices" are (they're likely just deprecation warnings, not failures):

Good — the "PHPUnit Notices" are just deprecation warnings from PHPUnit 13 about missing void return type declarations on test methods (shown as `N` in the progress bar). They don't affect correctness.
## VERDICT: APPROVE ✅
### What was verified
**Source code (FAULT-012 fix in `RateLimiterModule.php`):**
- Line 216: `$ip = $_SERVER['REMOTE_ADDR'] ?? '127.0.0.1';` — uses REMOTE_ADDR as source of truth, with CLI fallback
- Line 220-227: X-Forwarded-For read for **debug logging only**, using `json_encode()` for log injection mitigation
- Comment at line 215 explicitly states X-Forwarded-For is attacker-controlled and not used for enforcement
**Stub fix (`InterfaceStubs.php`):**
- `WP_REST_Request::get_header()` returns `?string` (line 71), defaulting to `null` (line 73) — correct mock behavior
**6 test scenarios:**
| # | Scenario | Key coverage | Status |
|---|----------|-------------|--------|
| 1 | Spoofed X-Forwarded-For → REMOTE_ADDR used | IP resolution | ✅ |
| 2 | No X-Forwarded-For header → REMOTE_ADDR | Absent header handling | ✅ |
| 3 | Multi-IP cycling with spoofed X-Forwarded-For | Consistent key + 429 response | ✅ |
| 4 | CLI fallback (no REMOTE_ADDR) → 127.0.0.1 | Edge case | ✅ |
| 5a | X-Forwarded-For read on billing routes | Debug logging wired correctly | ✅ |
| 5b | X-Forwarded-For NOT read on non-billing routes | No unnecessary reads | ✅ |
| 6 | Mock returns null for absent headers | Across tests 11 & new test 2 | ✅ |
**Test results:** 11/11 tests pass, 47 assertions, 0 failures, 0 errors.
### Issues found
- None in the test additions. The 7 errors in the full suite are all **pre-existing** and unrelated (`RateLimitRepositoryTest` missing `ProfeDB`, `RateLimiterTest` missing fixtures).
**Conclusion:** The 6 new test scenarios correctly cover the FAULT-012 fix (REMOTE_ADDR as source of truth, X-Forwarded-For for debug only, CLI fallback, log injection mitigation) and the mock fix (get_header returns null). **APPROVE.**
