Evidence Model

Evidence model

How Velvt separates events, observations, actions, effects, findings and provenance.

Velvt preserves evidence as a sequence of distinct layers rather than collapsing everything into a single pass/fail result.

event → observation → action → effect → interpretation → finding

Provenance and tested representation apply across the entire chain.

Two distinctions matter everywhere

DECLARED ≠ OBSERVED
INTENTION ≠ ATTEMPT ≠ EFFECT
