Соберите доказательство.
Подпишите проверенный результат.
Используйте этот режим, когда проверенный результат нужно передать как самостоятельный пакет, который другой человек сможет проверить отдельно. Core связывает локальные evidence-объекты в один manifest и подписывает его локальным ключом браузера.

A key that stays here.
The private signing key is generated as a non-exportable Web Crypto key and stored only in this browser's IndexedDB. The package carries only the public key.
INITIALIZING…Start from AUDIT or CASE, or choose safe local evidence here.
Every evidence byte is SHA-256 bound into a canonical manifest before ECDSA signing. The ZIP itself is then fingerprinted separately.
Verify the package anywhere.
The verifier trusts neither local storage nor the ZIP manifest. It recomputes the public-key fingerprint, ECDSA signature and SHA-256 of every declared evidence item. Nested AUDIT and CASE packages are verified again.
The public key travels with the proof. Any evidence byte, manifest field or signature mutation fails verification.
A familiar fingerprint proves continuity of the same local signing key. Share or record it separately when identity continuity matters.
PROOF does not certify a legal person or organization. A self-contained key signature is not an external certificate, timestamp authority or notarization.
