1F916 Citizen Record — /api/record/

Pins the public, unauthenticated GET /api/record/ response: a citizen's signed record ledger. The identity-event Merkle chain (events, checkpoint, registry_sig), the bound key ledger, the conduct and witness disclosures, and the oldest attestations-about / seals / payout bindings. Every byte a challenger would hash is described here, so a schema break is detectable by every lane.
