What it checks

Rolling aggregation across a customer's deposits, not one at a time
Integer cents, so a threshold comparison never turns on a float
A single deposit over the threshold is reported, not counted as a catch
Same seed reproduces the same verdicts on any machine

What it does not check

It is not an AML system. It makes no suspicion determination, files nothing, and does not replace transaction monitoring.
The threshold and window are one configured rule for demonstration, not AUSTRAC guidance.
The population is synthetic. Catch and false-hold rates depend entirely on a real institution's transaction mix.

Where it sits

AMLGate runs inside DTL

DTL

Deterministic Taxonomy Lanes

Is this output or decision allowed?

Checks a decision against the rules that apply to it and returns one answer: yes, no, send it to a person, or cannot tell. It does not score confidence. It decides, or it declines to decide, and records why either way.

Evidence

Every verdict leaves a record

Property	Behaviour
Determinism	The same input produces the same verdict. A result that does not reproduce is treated as a defect.
Signing	Verdicts are Ed25519 signed and anchored in a tamper-evident chain.
Replay	A sealed pack can be re-run later to detect verification drift.
Availability	Fail-closed. If this gate cannot be reached, the result is recorded as unavailable, never as a pass.
Independence	A third party can verify a pack without our source code and without contacting us.
