Evidence-ledger Ed25519 public key (unauthenticated trust anchor)

Publishes the PUBLIC half of the evidence-ledger Ed25519 signing key — the trust anchor an auditor pins out-of-band to verify exported evidence offline, via `evalguard verify <export> --public-key` or the `@evalguard/core/verify` library. Unauthenticated by design: a public key is public, and an auditor verifying an export must be able to fetch the anchor without holding a credential for the organization being audited. The private half never leaves the server; only the SPKI public key and its `keyId` are returned. Fail-closed: when ledger signing is not configured this returns 503 LEDGER_KEY_UNAVAILABLE rather than an empty or placeholder key. Cached for 1h; a redeploy invalidates. Format and the full verification algorithm: docs/compliance/evidence-verification-spec.md Authentication: none. This is a public endpoint and no credential is read. The empty `security` is a deliberate statement rather than an omission — nothing on this path resolves a caller, so no API-key scope is evaluated and an `eg_` key sent anyway is ignored.

Authentication

Public endpoint. No credential is read — send the request without an Authorization header. This is a deliberate statement, not a missing one.

Response

200 example

{
  "success": true
}

All status codes

200The SPKI public key and its keyId.
403Forbidden — the credential is valid but lacks the API-key scope, member role, or plan entitlement this operation requires.
429(no description)
500Internal Server Error — an unhandled error was converted to the standard error envelope (INTERNAL_ERROR).
503LEDGER_KEY_UNAVAILABLE — ledger signing is not configured on this deployment.
