Minimize
Collect only what the case and approved workflow require.
Human approval required
Non-negotiable controls
Human authority is an architecture decision.
Sentinel is designed to make uncertainty visible, preserve evidence, minimize personal information, and stop before any consequential external action.
Make uncertainty legible
A finding is not a verdict.
Agent output keeps six kinds of information separate so a reviewer can see what is known, what is inferred, and what still needs approval.
- 01Observed facts
- 02Assumptions
- 03Inferences
- 04Unknowns
- 05Recommendations
- 06Required approvals
Human approval required
The system must stop here.
These actions always require an accountable human with the authority and context to decide.
Qualified local compliance staff remain responsible for legal interpretation and filing decisions in every jurisdiction.

Refuse, freeze, or hold a transaction
Approval - 02
File a regulatory or law-enforcement report
Approval - 03
Submit phishing, abuse, or public wallet reports
Approval - 04
Disclose customer personal information
Approval - 05
Contact a third party
Approval - 06
Make a customer-facing fraud accusation

Evidence handling
Preserve where a claim came from.
Evidence records are designed to carry provenance and redaction state forward. The pilot does not claim an immutable chain-of-custody ledger.
EV-00421Synthetic record
01Source reference
02Capture timestamp
03Confidence level
04Hash when applicable
05Chain-of-custody note
06PII and redaction status
Privacy by constraint
Use less personal information, not more.
Redact
Remove PII from evaluations, public reports, and improvement notes.
Separate
Treat live case input as case data—not durable instruction.
Protect
Never use protected traits as fraud indicators.
Synthetic evaluation suite
Test the escalation—and the restraint.
The evaluation design includes clear scam cases, a high-risk wallet flow, a distressed-customer scenario, and a legitimate purchase that must not be over-escalated.
- E01Romance / investment scam
- E02Fake withdrawal tax
- E03Job / task scam
- E04Recovery scam
- E05Suspicious phishing URL
- E06High-risk wallet flow
- E07Legitimate self-custody purchase
- E08Distressed victim interaction
Customer-safe language
Interrupt the payment without humiliating the person.
