CHTR Ceremony Console

The master key that protects every chain-signed surface — audit logs, the Lahti–Iris™ Codex, compliance attestations, IP register, per-entity action chains — is split into 5 Shamir shares held by 5 custodians. Any 3 of 5 must release their share to unseal the key for a rotation or recovery ceremony. A single compromised account or device cannot unseal the system alone.

BETA — WebAuthn proof is in flight, not yet enforced. The frontend signals mfa_factor: "guardianorb_biometric" on share release but does not yet sign a WebAuthn challenge; the backend stores mfa_proof_id as received without verification (Phase 1, Task #125). Until that ships, only audit_dry_run ceremonies should be exercised. A backend interlock to refuse production grants without a verified proof is on the open list — see audit_logs #24686 for the chain-stamped infrastructure-fix bundle from earlier today.

Ceremonies must be initiated by a senior officer (role ≥ 4). Each share release is locked behind GuardianOrb biometric MFA — phishing-resistant. Every step is signed in the Codex.
