Concepts: identity trust, TOFU, and safety numbers #626
Description
Branch: Open your PR against dev. PRs targeting main are closed automatically.
Description:
Write apps/web/docs/concepts-identity-trust.md for lib/identityTrust.ts and its UI in app/app/conversations/[id]/page.tsx. The server enforces key-format invariants but has no notion of "is this still the identity key I trust" — that is a client-side trust-on-first-use decision, as in Signal.
Acceptance criteria:
- Documents the trusted-snapshot model (
trustDevices,getTrustedSnapshot,checkIdentityChange) and where it is persisted (localStorage, with an in-memory fallback) - Documents exactly when
IdentityKeyChangedErroris raised, whatonSessionResetsubscribers do, and what the user is shown - Documents how the safety number is computed from the backend key-fingerprint endpoint and how two users compare them
- States the limits: TOFU trusts the first key seen, and clearing browser storage resets trust silently
