Every observability tool records what happened. OMEGA records what was evaluated and not acted on — before execution. Non-action is a governed event. This is what one looks like.
Authorising entity: Fraud Prevention Policy v4.0
Authority: Enterprise Risk, Card and Payments
Constraints: Block only when risk score exceeds 0.85 and velocity rules flag cross-border exception.
Scope confirmed: YES
We know: Transaction risk score 0.91.
We know: EU card, APAC IP — geo mismatch detected.
We know: Prior 24h velocity exceeded rolling threshold.
We concluded: Transaction exceeds block threshold.
We assumed: Risk model calibration current for product line.
UNKNOWN: Customer travel status not on file.
Action: Block settlement for transaction TXN-2026-88821
Data fingerprint: sha256:4b2a8f9e... — proves exactly what information the AI used

If this goes wrong: Customer confirms legitimate transaction via verified channel within 24 hours
Prediction independence: SEPARATE

Separate system: YES
Five foundational primitives complete — see /spec/v1/ for the full v1.3 primitive set. This record cannot be changed or deleted.
Why HELD matters: the system evaluated this transaction and chose not to act. That decision is as important as any action. Without a governed record, there is no trace that the system ever considered it. For regulators and insurers, the decision not to act is often more important than the decision to act — it proves the system evaluated and rejected, rather than simply never triggering.
