Actions

Maker-checker: blocklist changes and SAR filing require a distinct approver (the MLRO approves the SAR). Every action lands in the hash-chained WORM audit.

Fraud and AML Console

One High alert has 8 minutes left
ALT-2026-4471 has 8 minutes of its 1 hour window left. A High alert that breaches does not close itself and is not downgraded. It escalates to the MLRO and the breach is recorded against the team, because an alerting standard nobody measures is not a standard.

What counts as first actionAssigning it is not enough. A decision or a documented step is.

Fraud and AML Console

Who has what, and what nobody has
An unassigned case is nobody responsibility, so the console shows that plainly. Cases carry an assignee chip and can be reassigned, and the queue is deliberately not auto-distributed: an analyst picking a case up is a decision worth recording.

Your freeze is with a checker
The wallet is not frozen yet. Freezing somebody money is a serious step, so it needs a second operator even when the analyst is sure. What is in force right now is the lighter measure: a step-up on their next sensitive action.
