New crate crates/kv-wasm runs the same crypto, item model and sync engine in the browser:
- WebStore: in-memory replica of kv-store's Store, each changed entry written to IndexedDB
(ciphertext only) before the JS call resolves.
- Device key: non-extractable WebCrypto ECDSA P-256 key in IndexedDB (raw r||s signatures).
- WebCore mirrors kv-ffi's VaultCore; wasm-bindgen surface in camelCase with TypeScript types,
plus a Web Worker wrapper (connectVault) so Argon2id never blocks the page.
- Tests: Chrome (IndexedDB, WebCrypto, RFC 9421 verify), shared envelope fixtures both ways
with kv-ffi, native sync with kv-ffi via the test server, Node smoke of the built package.
Small changes to shared crates so they build for wasm32:
- kv-store: SqliteStore moved to a native-only module.
- kv-sync: rustls/pinning/tokio native only (fetch on wasm); DeviceSigner::sign_async (default
wraps sign) used by ApiClient; unix_now() instead of SystemTime/now_utc.
- kv-model: Public Suffix List behind a default `psl` feature (kv-ffi keeps it; the web build
drops ~0.9 MB of code and matches same-host only).
- wasm-release profile (opt-level z, Argon2 at 3) and a wasm CI job.
