Recorded event
INTERNAL AUTHENTICATE doesn't return your PAN. The chip signs a challenge — it doesn't reveal account data.
We don't read cardholder name or track-2 data. Only the application ID and the chip's response.
Each event uses a fresh random nonce. Replaying an old chip response against a new challenge fails.
