  "about": "Conformance vectors for independent implementations of the Rightshold Ledger verifier. Each vector is a daily-snapshot pair (a signed manifest and its body) plus the key set it is verified against. In these vectors the snapshot body travels as a JSON value; its bytes are the canonical serialization (keys sorted, no whitespace, UTF-8) — the same serialization the ledger's hashing rules state. A conforming verifier accepts the known-good vector in full and rejects every altered vector, failing at least the checks named in expect_failing_checks. Regenerate and compare: node scripts/gen-conformance-vectors.mjs in the published tooling reproduces this document byte for byte.",
