# Evidence Over Assertion A claim earns its verdict only with cited evidence: a command actually run, a file:line actually read, an authoritative value actually re-queried. When the evidence cannot be collected, the verdict degrades and says so — it is never rounded up. **Why:** A confident wrong answer is the most expensive kind. Assertions compound: one unverified claim adopted into a report becomes the evidence for the next wrong decision. **Pattern:** - Verify by re-querying, never by memory. A zero exit means the mutation was accepted, not that the change landed — re-read the authoritative value and confirm the property you meant to establish. - No PASS without cited evidence; an unverifiable item is reported as unverifiable at its degraded confidence. - Ground every verdict in a load-bearing fact you observed yourself, and name it. A third party's claim (a comment, a vendor finding) is never the sole evidence — verify it at a concrete file:line before adopting. - Agreement is corroborating signal, never proof. Another reviewer's or model's concurrence does not substitute for your own check.
