-kirakira began as [FlashMail](https://github.com/sarthakkimtani/flash-mail), a Flutter UI template for a disposable-email app built on mail.tm. Its protocol core is now [fumi-core](https://code.randogoth.com/randogoth/fumi), the Rust library the reference CLI is built on: `native/` wraps it into a C ABI and ships it in the APK as `libsmol_mail_native.so` (SQLite bundled), `lib/native/` speaks that ABI over dart:ffi, and `lib/smol/` is the thin facade the UI reads. The UI is Material 3 — dark navy and mint green by default, with a matching light theme — built from a single `ColorScheme` and `AppColors` extension rather than hardcoded colors per screen.
+kirakira began as [FlashMail](https://github.com/sarthakkimtani/flash-mail), a Flutter UI template for a disposable-email app built on mail.tm. Its networking layer was replaced end to end with a from-scratch Smol Mail implementation (`lib/smol/`: crypto, Noise handshake, framing, client flows), and the UI was redesigned around a Material 3 theme — dark navy and mint green by default, with a matching light theme — built from a single `ColorScheme` and `AppColors` extension rather than hardcoded colors per screen.

 - Trust-on-first-use for server and contact keys, with rotation support and on-screen warnings for anything unverified.
 - Export/import inbox, sent mail, contacts and server pins as one shareable backup file — never the seed.
 
-Mail, contacts and pinned server keys live in fumi-core's SQLite store, bundled into the native library; the seed, read marks and settings stay app-side in Hive.

 ## Layout
 
 ```
-lib/native/        dart:ffi binding: handles, error codes, isolate plumbing
-lib/smol/          thin facades over the binding: address, store, client
+lib/smol/          the protocol: crypto, Noise handshake, framing, client flows
 lib/presentation/  screens, widgets and theme (Riverpod + auto_route)
 lib/data/          Riverpod providers
-native/            Rust wrapper crate: the C ABI over fumi-core, pinned by rev
-integration_test/  Patrol device tests against a live server
-test/              store, recall, binding, interop and e2e tests
+test/              protocol vectors, store tests, a live e2e round-trip
 ```
 
 ## Run and verify
 
 ```
-devbox run build-native-android   # the .so the APK loads — once per Rust change
 devbox run analyze
 devbox run test
-flutter run --flavor prod
+flutter run
 ```
 
-`test/e2e_test.dart` runs a live round-trip against the local bunshin on `127.0.0.1:1961` and skips itself when nothing's listening there. On-device flows are covered by the Patrol suite — `devbox run test-integration` builds the `integration` flavor (installed beside the real app, its data cleared between tests) and drives onboarding, registration, fetch cancellation, rotation and the unchanged-key refresh against the same server.

+## Notes and limits
+
+- No server push in v1 — fetch is manual.
+- The seed lives in app storage; a compromised device is a compromised identity.
+- Rotation isn't revocation — a stolen key can still rotate onward. Settings surfaces rotations for out-of-band verification rather than applying them silently.
