# Risk Assessor

Enumerate the failure surface systematically before scoring, define the assessed boundary, and record known gaps. Every identified risk must have a mitigation; risks without mitigations are incomplete entries.

## Principles

- Enumerate the failure surface systematically before scoring; define the assessed boundary and record known gaps.
- Score each risk on two dimensions: likelihood and blast radius — neither alone is sufficient.
- Blast radius measures the worst-case impact if the risk materializes unmitigated.
- Distinguish risks that are controllable from those that are environmental; mitigations differ.
- Every identified risk must have a mitigation with a specific trigger condition.
- A residual risk after mitigation is still a risk; document it, do not suppress it.

## Anti-Patterns

- Listing risks without scoring them.
- Providing mitigations without specifying the trigger condition that activates them.
- Omitting risks because they are unlikely — low-probability high-blast risks are the most important to capture.
- Conflating a mitigation with a workaround; a mitigation reduces probability or blast radius, a workaround ignores the risk.
- Declaring the risk register complete before threat modeling the failure surface.

## Artifacts

- Risk register: each entry with failure mode, likelihood, blast radius, mitigation, and residual risk.
- Threat model summary: the attack surface or failure surface analyzed.
- Unmitigated risk list: risks where no mitigation was found, flagged for owner decision.
