TokenGuard: JWT Replay Integrity

Developers recording API tests with JWT libraries capture sign/verify results, causing replay to accept expired tokens and produce false positives. TokenGuard enforces real-time token validity during replay, accurately simulating expiration and preventing temporal context leakage.

Comment on: Show HN: Tusk Drift – Open-source tool for automating API tests

We instrument JWT libraries directly (jsonwebtoken, jwks-rsa). Both `jwt.sign()` and `jwt.verify()` are captured during recording and replayed with the original results. During replay, you get back the recorded verification result. So if the token was valid during recording, it stays valid during replay, even if it would be expired "now". The test runs in the temporal context of when it was recorded.
