Cryptographic Verification of 500k Transactions

Technical breakdown of an immutable audit trail implementation for a leading Neo-Bank.

1. The Problem: Data Integrity

Financial auditors required a 100% verifiable log of agent actions to prevent unauthorized transaction loops.

2. The Solution: Parquet Hash-Chaining

By utilizing the `browser.get_audit_log` method, the bank built a real-time monitoring engine that verified the cryptographic signature of every browser state transition.
