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.

* kv-proto: ticket and join wire types, LoginFinish.ticket, b64_opt.
* kv-crypto: pairing.rs (HPKE AuthPSK seal/open with the QR secret as PSK, SAS code).
* kv-sync: onboarding.rs (kestrove://setup/v1 and kestrove://join/v1 codec with
strict validation), ApiClient ticket/join calls and login_with_ticket, test
server support for tickets and rendezvous.
* kv-ffi: parse/encode_setup_payload, setup_payload_for_kit, add_device_payload,
revoke_enrollment_ticket, login_with_setup, join_start/poll/cancel,
join_approve/send. The Secret Key is kept locally, HPKE-sealed to enc_pk.
* Tests: codec round trips and rejections, AuthPSK tamper cases, end-to-end
Add-device QR and scan-to-join between two clients, forged bundles, bound
tickets; live test extended with scan-to-join.

New module crates/kv-ffi/src/passkeys.rs; lib.rs only gains the mod/pub use lines.
Tests verify registrations and assertions like an RP (ciborium + p256), check RP isolation,
reopening the vault and use on a second device after a sync.

kv-store: SQLite (bundled) and in-memory Store holding only ciphertext
envelopes, with base copies for three-way merges and a 10-version history.
kv-ffi: VaultCore::open(path); persisted account record; local unlock key
(enable/unlock_with_local_key/disable); async sync API (configure_server,
set_device_signer, register_account, login, sync_now, logout, devices);
DeviceSigner foreign trait; IntegrityAlarm/PinMismatch/... error variants.
kv-sync: reqwest + rustls (TLS 1.3 only, ring) with SPKI pinning; OPAQUE
client on kv-proto's OpaqueSuite; RFC 9421 signing per kv_proto::httpsig;
pull/push with If-Match, field-level three-way merge, edit-beats-delete;
signed manifest (canonical CBOR, Merkle root, prev chain, Ed25519) with
rollback/fork/Merkle checks as hard integrity alarms. Tested against a
wiremock fake server, plus an #[ignore] test against kestrove-server.
kv-crypto: gen-vectors example and tests reproducing kestrove-spec/vectors.
