Unreleased

appVersion stays required here, while the Swift and Flutter SDKs now detect it. React Native exposes nothing that reads the host app's version. Reaching the bundle needs a native module, and this package having none is worth more than saving a caller one argument. Documented rather than papered over.
Removed the kill switch, following its removal from the protocol. Evaluation order is now maintenance → force → soft → none. Old payloads that still carry a kill block parse fine; the block is ignored.

First release.

Force update, soft update, kill switch and maintenance mode, decided by the protocol's evaluation order and verified against the golden vectors.
Remote config values in the same signed payload, so there is no extra request.
Ed25519 verification of the exact response bytes, with SHA-512 wired for runtimes without crypto.subtle, which is all of React Native.
Signed cache, re-verified on read. AsyncStorage adapter, no dependency on it.
RipstopProvider with prebuilt walls, or useRipstop() and draw your own.
