# Evidence, Assessment, and Decision Memory
## Evidence ladder

1. **Observation** — what a player, sensor, or authoritative system directly recorded.
2. **Source report** — what a human or synthetic source communicated, with source identity and access separated from the claim.
3. **Interpretation** — what the reported material may mean.
4. **Hypothesis** — a testable explanation that competes with alternatives.
5. **Assessment** — a judgment with confidence, supporting evidence, contradictions, and gaps.
6. **Decision** — an authority action informed by the assessment and its stated uncertainty.

## Required metadata

UTC timestamp, collector, authority, operation, source, access basis, provenance, transformation history, chain of custody, corroboration, contradiction, confidence, dissemination restrictions, and reversal references.

## Consequence doctrine

Severity and evidentiary certainty are separate axes. The server can know an event occurred while the fictional world still needs witnesses, sensors, records, or corroboration before a formal warrant or irreversible action is justified.
