# PlatPhorm Evidence

> Deterministic claim verification ledger for security investigations. Every claim is checked against resolved evidence, coverage gaps are surfaced explicitly, and every verdict is receipted by content digest.

This service is the Evidence layer of the PlatPhorm network. It does not
investigate or correlate; it verifies. A claim is checked deterministically
against resolved evidence. Missing coverage is reported as a gap, never
guessed. Every verdict is anchored by a content digest and issued a receipt.

## Determinism contract
- Same claim + same evidence references => identical verdict and digest.
- An unresolved reference can never satisfy a reference-integrity check.
- Verdict precedence: CONTRADICTED > UNSUPPORTED > UNVERIFIABLE > PARTIALLY_SUPPORTED > SUPPORTED.
