Swap the chat transport from the kez-chat server inbox to Nostr relays without touching the identity model or the E2E crypto. The existing SealedEnvelope (ed25519/x25519 + AES-GCM, our own key) is unchanged and becomes the content of a Nostr event — Nostr only moves the bytes. - nostr-id.ts: derive a secp256k1 signing key from the ed25519 seed (HKDF, domain-separated — internal transport credential, never the user's real Nostr account); route by a hash of the recipient's public ed25519 primary since the curves can't be cross-derived. - nostr-transport.ts: send/poll/stream mirroring messages.ts, via SimplePool; per-handle time cursor + seen-id dedupe in localStorage. - transport.ts: facade selecting server vs nostr via VITE_TRANSPORT (code default stays "server"; this branch's .env flips it to nostr). - inbox-service + Messages import from the facade. Directory lookup (handle->primary) still runs on the kez-chat server; identity stays internal. Metadata privacy is at parity with the server transport (relay sees the from/to graph, body stays confidential). Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>
