Add wacore-recordstore: a byte-level RecordStore and LeaseStore that a database adapter implements, and RecordSignalStore, which builds the full SignalStore on top of them. Every write carries the fence of the lease that authorised it and is applied only while that generation is current, so a node that lost its lease cannot overwrite its successor. Every value is sealed by a Sealer (AES-256-GCM by default) with scope, namespace and key in the AAD, so a record cannot be moved to another slot. Prekey upload marks use an update-only write and never resurrect a consumed key. Includes a conformance suite for adapters, the in-memory reference store, and a wasm32 CI build.
do_pair_crypto only uses the identity key and the ADV secret, but takes a DeviceState that also carries the noise key pair. Add do_pair_crypto_with, which takes just the two secrets it uses, and delegate to it. A Signal store that holds the identity key but never the noise key can now complete pairing. Behaviour is unchanged.
Add wacore-signal-ops: the operations a WhatsApp client needs from a Signal store it does not hold the private keys for. Decrypt pkmsg/msg, encrypt, establish a session from a fetched bundle, sender-key distribution and group encrypt/decrypt, one-time prekey generation, signed prekey rotation, and the pairing device signature. The pairing operation verifies the primary's container and signs only the ADV device-identity message it builds itself, never caller-chosen bytes. A consumed one-time prekey is deleted only after the promoted session is written. Records use wacore's for-store encodings with a per-process incarnation, so a failover reload skips past possibly used chain positions. wacore-recordstore gains a sealed Device namespace for the local key blob. End-to-end tests run two devices over sealed, fenced record stores: both directions, group sender keys, signed prekey rotation, pairing, and a node failover in which the superseded node is fenced out.
Add wacore-signal-wasm, a wasm-bindgen wrapper around wacore-signal-ops. The page supplies a RecordBackend (IndexedDB in a browser) and a Sealer (WebCrypto, so the data key can stay non-extractable); SignalDevice takes the scope's lease and exposes decrypt/encrypt, session setup, sender keys, prekeys, signed prekey rotation, pairing and lease renewal. Errors carry a code: fence_lost, lease_held, pairing_refused, invalid_input, signal, store. The crate compiles only for wasm32. CI builds it, generates Node glue with the wasm-bindgen CLI pinned to Cargo.lock, and runs two devices end to end from JavaScript with a WebCrypto sealer, including a second tab being refused and then fencing out the first.
Decrypt now runs against a staged view of the record store: the ratchet advance, the consumed one-time prekey's removal, any sender-key distribution carried in the message and the buffered result are sealed and written as one fenced batch. A node fenced out mid-receive commits nothing, so its successor still decrypts the same ciphertext. SignalOps::receive decrypts, buffers and classifies a payload with wacore's process_decrypted_plaintext. Redelivery before mark_delivered returns the buffered result; after it, AlreadyDelivered. App-state key shares are surfaced only from the account's own devices, as WA Web gates them. prune_decrypt_buffer drops old entries. wacore-recordstore gains staged views (RecordSignalStore::staged/commit) and DecryptBuffer/SentMessage namespaces reachable through a separate aux API. The wasm bindings expose receive, markDelivered and pruneDecryptBuffer.
SignalOps::send_direct takes the app's waE2E.Message and builds the finished <message> stanza with wacore's prepare_dm_stanza: padding, own-device copies, per-device encryption and session setup from bundles. The WhatsApp client only answers device-list and prekey queries through SendContextResolver and transmits the bytes, so it never sees plaintext. Session changes and the sent-message record (for retry receipts) commit before the stanza is returned. DeviceKeys moves to format 2, adding the paired ADVSignedDeviceIdentity and own PN/LID JIDs; format 1 still decodes. sign_pairing persists the signed identity and set_own_jids records the JIDs after pair success. Every state-changing operation now holds one lock per device: staged views commit whole batches, so concurrent views on the same session would lose a ratchet step.
SignalOps::send_group builds the group stanza with wacore's prepare_group_stanza: the skmsg plus, for devices that do not hold this device's sender key yet, the key encrypted pairwise. Membership and addressing come from the resolver, and LID-mode members are queried by phone number then mapped back, as the client does. A missing own chain forces distribution to every member device. Otherwise only devices not marked warm receive the key, and a companion counts as warm only when its primary does (WA Web's primary-device gate). mark_sender_key_distributed records devices after the server acks, never this account's own devices (WA Web's !isMeDevice); forget_sender_key_devices resets a group after membership changes. Marks live in a sealed SenderKeyDevices namespace.

Explanation
The title "Customer-held Signal state: fenced sealed store and Signal operations" matches the main change. The PR adds three crates: wacore-recordstore (sealed, lease-fenced storage), wacore-signal-ops (Signal receive, send, retry, prekey, pairing operations), and wacore-signal-wasm (JavaScript bindings). The title is specific and in one sentence. It names the sealed store and Signal operations but omits the WASM bindings and the do_pair_crypto_with refactor, which are secondary to the main change.

SignalOps::resend answers a retry receipt from the sent-message store with wacore's prepare_pairwise_retry_stanza, using the client's routes: direct to the requesting device, or to the group/list with the requester as participant. Keys carried by the receipt start a fresh session; without a session or keys, a bundle is fetched through the resolver, as the client does. Status retransmission is not handled here. establish_session now stages and commits atomically through a shared establish_into. Tests cover a lost delivery and a device reset, with the pairing helper moved to tests/common.
The bindings expose setOwnJids, sendDirect, sendGroup, markSenderKeyDistributed and forgetSenderKeyDevices. The page supplies a SendResolver that relays device-list, prekey and group-routing queries to the WhatsApp client; a PageRuntime runs wacore's spawned work on the JS event loop and times out through setTimeout. Messages travel as encoded waE2E.Message bytes and stanzas come back marshaled, ready to transmit. RemoteBundle::to_prekey_bundle is now public so the bindings validate JS bundles the same way the service does.

- recordstore: length-prefix every AAD component so no two (scope, namespace, key) slots seal alike; NUL-joined fields were ambiguous. - recordstore: add WriteOp::Insert (exclusive, fails the batch with RecordExists); SignalOps::create uses it, so concurrent initialisers cannot both write device keys. Covered by the conformance suite. - signal-ops: replace the device-wide lock with keyed locks on the state each operation writes (peer session, sender-key chain, group marks), taken in sorted order. Sends fix encryption addresses up front so the locks cover the sessions they write. A slow prekey fetch no longer blocks unrelated decrypts; process_sender_key_distribution now locks. - signal-ops: strip app-state key shares and requests from non-own senders out of the delivered message, not only the gated field. - signal-ops: a malformed sender-key distribution no longer aborts receive; the message commits and reports sender_key_rejected. - signal-ops: timestamp sent-message records and add prune_sent_messages. - signal-wasm: build protocol addresses with JidExt::to_protocol_address, release the lease when open fails, map insert/record_exists, and drop a rustdoc link that cannot resolve on native targets.
A group retry receipt means the requester may have lost this device's sender key. resend now forgets the requester's distribution mark for the group, so the next group send gives it the key again, matching WA Web and whatsapp-rust's mark_requester_for_fresh_skdm. The group test covers a retry followed by redistribution.
SignalOps::forget_user drops the stored identity and session of every device of one user (matching user and server exactly), under the session locks, in one fenced batch. Exposed to JS as forgetUser. This is the store side of HyperMeow's RemoteSignal.ForgetIdentity.
- SignalOps::migrate_pn_to_lid moves a user's sessions and identities from phone-number to LID addresses, for regular and hosted devices, in one fenced batch under the session locks. PN session wins, LID identity wins, sender keys stay (as whatsapp-rust and WA Web do). Exposed to JS as migratePnToLid. - forget_user also covers the user's hosted (or hosted LID) devices, matching HyperMeow's local identity-change cleanup. - Address matching requires a numeric device suffix, so 'hosted' no longer matches 'hosted.lid' addresses.

insert_prekeys_batch rejects a batch that repeats an ID before staging, so commit cannot succeed with fewer private keys than supplied. Sent-message and decrypt-buffer pruning delete records that no longer decode instead of stopping at the first one.
crypto-bigint 0.5 is reached only through wa-fetch's OxiTLS RustCrypto provider in tools/oracle-task; the workspace graph does not contain it.

When a participant who already received the sender key leaves, calling this method as documented only clears distribution marks; it leaves the sender-key chain intact. The next send_group therefore redistributes and advances the same chain, allowing the removed participant to decrypt subsequent ciphertext if obtained. The existing client's rotate_own_sender_key_state deletes both own-address chains as well as distribution tracking. Provide an equivalent fenced, atomic rotation operation here and expose it through the WASM binding; repo-wide searches of the new service and binding found no sender-key deletion or rotation path.

For messages whose reporting context is generated by prepare_dm_stanza or prepare_group_stanza, the stored message bytes do not contain that context: encode_sent saves the generated secret separately. This decoder discards that secret, and resend passes the resulting bare message to prepare_pairwise_retry_stanza, which only encodes and pads it. Consequently, a device receiving the message through a retry gets no original message_secret and cannot use secret-dependent follow-up payloads for that message. Decode the saved secret and restore its message context before retry encryption.

When the resolver knows a device's LID but only its PN session exists, this locks only the LID address. The new address memo does not prevent the fallback: ensure_sessions_for_devices_resolved in wacore/src/send/encrypt.rs explicitly selects the existing PN session when the LID session is absent, and the fan-out encrypts using that selected address. A concurrent receive or low-level encrypt on the PN address therefore takes a different lock while modifying the same session, allowing lost ratchet updates or duplicate outbound chain positions. Include both the original device address and its preferred LID in the sorted lock set, as the group-send path already does.
