Type Alias: EvidencePosture

EvidencePosture = "assist" | "guard" | "rails"

Defined in: src/core/agent/evidence/types.ts:30

How hard the check pushes back. Same three words as the skill-graph routing dial, deliberately — one posture vocabulary across the library — but a SEPARATE option, because routing authority and evidence discipline are different decisions and an app may legitimately want strict routing with loose evidence (or the reverse).

• 'assist' — the default. Record and flag. The answer goes out exactly as the model wrote it; nothing loops, nothing is withheld. Pure observability: you learn how often it happens before you decide to act. • 'guard' — in-loop correction. The unsupported values are named back to the model, it gets ONE more turn, and if they survive that turn the answer ships flagged. This is the posture that makes a small model behave like a bigger one, and it is the recommended setting for weaker models. • 'rails' — 'guard' plus a refusal: if the values survive the one revision, run() raises instead of returning the answer.
