The Ed25519 signature authenticates the exact public manifest bytes, including the release inventory. The manifest in turn binds this run's source aggregate by its SHA-256 digest and byte size.

Verify the evidence chain
- Verify the detached Ed25519 signature over the domain-prefixed exact manifest bytes using the published public key.
- Confirm that the sidecar payload SHA-256 equals the manifest SHA-256 shown above.
- Hash the source aggregate and compare its SHA-256 and byte size with the signed manifest entry.
- Resolve this run ID through the public run index and match its campaign ID inside that aggregate.
