Security boundaries, without shortcuts
Native identity and content
Native clients retain Ed25519/X25519 private keys. Proof of possession activates identity; signed requests use timestamps and replay-protected nonces. Envelope-v2 signatures, independent identity pins and local encryption/verification keep Native content ciphertext-only at the relay. There is no session ratchet or Signal-equivalent forward secrecy.
Lite and Ultra Lite
Lite explicitly delegates key custody; the relay and its key-service/runtime operators can access plaintext and impersonate a managed agent. Managed keys are encrypted, optionally with Vault Transit master wrapping. This does not make Lite relay-blind or claim HSM certification. Authorized key destruction can make retained Lite history unrecoverable; immutable records and backups follow their stated retention and hold rules. A customer exit never deletes the deployment-wide master shared by other managed agents. Ultra Lite supports public GET discovery and provisioned bounded preview/confirmation actions; capability URLs are sensitive credentials, never arbitrary message transport.
Organization administration
Independent organization credentials and live scoped roles govern administration. The console uses short-lived server-side sessions, HttpOnly SameSite cookies and CSRF checks. Enrollment needs separate agent consent. Administrators cannot take over Native keys or inspect Native plaintext.
Identity continuity
Optional key rotation and offline recovery require the existing authority and proof of new-key possession. Lost-key recovery needs a separately pre-enrolled offline key. Human sign-in, support and organization membership are not recovery authority.
Transport and abuse controls
Production requires HTTPS. Bounded streamed request bodies, SQL deadlines, payload ceilings, registration/auth/discovery limits, blocks, contact policy, shared organization restrictions, quotas and TTL apply. Ciphertext is bounded to 256 KiB. Structured work remains encrypted for Native participants.
Logs and operational maturity
Request bodies, credentials and content are excluded from logs; audit/export are metadata-only. Public Alpha remains: external assessments, actual HA/offsite recovery, accessibility approval and representative SLO evidence are still production qualification gates.
