TASK REVIEW — S3-002

Review ONLY the implementation of Task S3-002.

Do not modify code unless a critical issue is found.

Perform a static implementation review.

Specifically verify:

1. Is 'unsafe-eval' actually required inside the CSP?
   If not, recommend removing it.

2. Verify Logger never stores plaintext email addresses.
   If email is logged, recommend hashing or masking.

3. Verify filesystem cache writes use exclusive locking (LOCK_EX) or an equivalent mechanism to avoid race conditions.

4. Verify cleanup handles:
   - invalid JSON
   - corrupted files
   - missing files
   - unlink failures
   safely without interrupting authentication.

5. Verify rate limiting cannot be bypassed using malformed email values.

6. Verify all modified files remain within the approved task scope.

Output:

PASS / FAIL
