Evidence before confidence.
A transparent method for understanding critical flows, challenging claims, and verifying selected capabilities safely.
From claim to decision.
Check the claim, evidence, and tested scenario. Assess failure consequences, then decide what to change, verify, monitor, or accept.
Claim
Name the capability to investigate. A claim is not a conclusion.
Evidence
Keep sources and provenance. Distinguish declared, observed, tested, inferred, and unknown.
Verify
Test selected claims in defined scenarios, with boundaries and safety controls.
Exposure
Assess business consequences of failure, separately from evidence confidence.
Decide
Choose remediation, validation, monitoring, or explicit risk acceptance. The customer owns risk decisions.
Act
Assign an owner, closure criteria, and evidence that the action worked.
Principles that keep uncertainty visible.
Critical Flow First
Start with a business outcome, acceptable behavior, and the dependencies it needs.
Claims, Evidence & Provenance
Challenge important beliefs. Keep sources, revisions, times, and interpretations. Distinguish declared, observed, tested, inferred, and unknown; more data alone does not strengthen a conclusion.
Controlled, Scenario-Bound Verification
Define approval, blast radius, monitoring, rollback, and abort conditions before execution. Results apply only to the recorded scenario and environment.
Risk Exposure ≠ Evidence Confidence
Failure consequences and evidence strength are separate. High exposure with weak evidence calls for urgent validation, not a reassuring score.
Keep Unknowns Visible
Record missing and contradictory information. Absence of evidence does not establish absence of risk.
Human Judgment & Risk Ownership
AI assists. Experts validate high-impact conclusions; independent review supports significant closure. The customer owns risk acceptance.
Exposure and confidence answer different questions.
High exposure
Stronger evidence
Decide / actHigh exposure
Weaker evidence
Validate urgentlyLower exposure
Stronger evidence
Consider acceptance / monitoringLower exposure
Weaker evidence
Investigate when usefulIllustrative prompts, not an automatic decision. Exposure describes the consequence of failure; confidence describes the evidence. Risk acceptance belongs to the customer.
Controlled verification, at the right boundary.
Disruptive production verification requires explicit approval, a defined blast radius, monitoring, rollback, and abort conditions.
- Review existing evidence
- Exercise in staging
- Run a controlled simulation
- Consider limited production validation
A separate exercise can contradict a claim
Illustrative example
Retries preserve one order per payment.
The selected simulation produced a duplicate order. The claim is contradicted in this scenario; broader behavior remains unverified.
Decision: investigate idempotency and verify the corrected path.
Independent fictional exercise
Choose one critical flow.
