# kosa8 evidence

Export and verify signed evidence packages

An evidence package is what kosa8 recorded about a sandbox, a snapshot,
an approval or a stretch of time, cut from the audit log so that it still
verifies: the audit entries with the chain segment around them, the seals
and signed approvals they name, the public keys, a readable summary, and a
manifest of every file by SHA-256, signed with Ed25519.

`kosa8 evidence verify` checks one with nothing but the package — no daemon,
no kosa8 state, no network. See docs/design/evidence.md.
