Implements TinySecurity contract 1.25 device pairing and session renewal for OpenHuman's DeviceFrame2 transport. The module owns per-scope pairing records, authenticated recovery, legacy per-channel identity import, and paired-tunnel lifecycle; host callbacks supply authenticated contexts and CAS persistence, while private keys and snapshots stay inside the module. Legacy import preserves each channel's original core identity and is all-or-nothing. Recovery merges the latest durable CAS snapshot before returning current channel metadata; tombstones continue to deny revoked imports.

The native module fixture exercises old channel-key Handshake and Renew, reinitialization-stable identity, and the lost-confirm path through Lock, Unlock, Recover, and Revoke. It also pins revoke/tombstone denial after reload and the deterministic reinitialization/Lock/Confirm races, plus negative scope, source, registration, backend, agent, expiry, corrupt-state, revoked-metadata, stale-generation, and replay cases. A denied legacy-import preflight leaves the loaded owner usable; after an import mutates state, snapshot generation and CAS persistence remain fenced so errors or cancellation fault and retire the scope. Lost-confirm recovery now uses the still-authorized replacement channel instead of the earlier revoked channel.

The required TinySecurity dependencies are available on main (#35 and #36 are merged). Host integration remains separately tracked by tinyhumansai/openhuman#7328 and is not claimed complete by this module PR.

Fresh local validation on head 9afdd7a231dbd4ae55dabaea076f777fbfae9ad0:

• cargo fmt --all -- --check
• cargo test --locked --workspace --all-features -j1 (all workspace tests and doctests passed; run with umask 077 so security tests create private temporary directories)
• cargo clippy --locked --workspace --all-targets --all-features -j1 -- -D warnings
• Built the native module and secret_cipher_native_contract, staged the shared library under a private umask 077 directory, then ran native mode 18; the device-pairing lifecycle passed.

The lockfile pins rustls-webpki 0.103.16 and webpki-roots 1.0.10 to address RUSTSEC-2026-0382 and RUSTSEC-2026-0381. Hosted CI and review are being re-run on this head.

Full summary

Pull request purpose (title): feat(crypto): add host-attested device pairing lifecycle (contract 1.25). Pull request purpose: feat(crypto): add host-attested device pairing lifecycle (contract 1.25). The change implements TinySecurity contract 1.25 device pairing and session renewal on top of the existing DeviceFrame2 transport. The module owns per-scope pairing records, proof-gated enrollment and renewal, authenticated recovery, legacy per-channel identity import and paired-tunnel lifecycle; host callbacks supply authenticated contexts and ciphertext-only CAS persistence, while private keys and snapshots stay inside the module. The contract bump to 1.25, wire types, callback vocabulary, crypto owner, module adapter, native mode-18 fixture and spec/plan/docs are part of the same change. No lane reported a confirmed defect, and this summary claims no test execution.

What changed

The latest push delta is unavailable: the review state holds a prior reviewed head (c370029) and the current head (20826ee), but there is no trusted base-to-head diff comparison, so nothing here is attributed to a specific push. This describes the whole-pull-request change.

Features

• Added — Confidential DevicePairing2 wire contract and callback vocabulary: Adds bounded, deny-unknown-field scope/configuration/operation/response/callback/persistence/legacy-load types that redact in Debug, carry only event ids, receipts or confidential protocol bytes in requests, and expose no caller-asserted scope, user, channel, source or key facts; adds the DevicePairing2 method name and the DevicePairingHost2 callback namespace with ResolvePairingEvent, PersistDevicePairing and LoadLegacyDeviceIdentities identities. (crates/tinysecurity-bus/src/device_pairing.rs, crates/tinysecurity-bus/src/names.rs pub const METHODS: &[&str] = &[, crates/tinysecurity-bus/src/callbacks.rs impl ApprovalCasRequest2 {)
• Added — Module-owned pairing and session lifecycle owner: Owns static identities, pending receipts, pairing records, revocation tombstones and tunnel sessions; enrollment commits only after an authenticated frame proves static-device-key possession, renewal requires the same key on a fresh socket, refresh preserves tunnel keys and replay counters, revocation retires sessions and pending receipts before tombstoning every channel, legacy import is atomic and idempotent, and lost-confirmation recovery merges the durable snapshot without discarding live tunnels. (crates/tinysecurity-crypto/src/device_pairing.rs, crates/tinysecurity-crypto/src/device_pairing_tests.rs, crates/tinysecurity-crypto/src/device_pairing/README.md)
• Added — Paired-tunnel registration in the existing frame registry: Paired sessions register as opaque handles in the DeviceFrame2 registry with generation/epoch/expiry fencing; register, refresh, single-handle retire and per-scope logout retirement fail closed on stale generation, wrong scope, duplicate handle, capacity overflow or clock rollback, and late frame validation fails after removal. (crates/tinysecurity-crypto/src/device_handles.rs impl Registry {, crates/tinysecurity-crypto/src/device_handles.rs struct Scope {, crates/tinysecurity-crypto/src/device_handles_tests.rs fn frame_revalidation_rejects_a_tunnel_after_generation_change() -> TestResult {)
• Added — Retained pairing-state cipher: Retains the HumanOnly master for pairing-state encryption/decryption inside the module using the existing enc2 format; the cipher survives alias expiry for routine persistence but is denied by registration epoch, module generation, registry shutdown and owner drop, and rejects plaintext persistence and disabled-encryption retention. (crates/tinysecurity-crypto/src/native_handles/cipher.rs pub struct CipherOwner {, crates/tinysecurity-crypto/src/native_handles/cipher_tests.rs async fn disabled_plaintext_empty_and_legacy_replacements_use_confidential_deliv)
• Added — Module adapter for DevicePairing2 with fenced persistence: Wires the confidential member to the crypto owner through fixed host callbacks, resolves the retained pairing cipher only through a validated alias bound to the exact registration, generation, scope and purpose, uses a delivery consumer that always denies so no plaintext reaches a host slot, and keeps a persistence fence across post-store authority checks and session publication so cancellation or failure faults the loaded scope and retires its paired frame handles. (crates/tinysecurity-module/src/adapter_device_pairing.rs, crates/tinysecurity-module/src/adapter.rs fn configured_confidential(, crates/tinysecurity-module/src/adapter_secret.rs impl SecretState {, crates/tinysecurity-module/src/adapter_secret_tests.rs mod linked_fixture {)
• Modified — Contract vocabulary and compatibility bump to 1.25: Adds the init-only device_pairing configuration slot to ModuleConfig, advertises DevicePairing2 in the method list and optional DevicePairingHost2 callback, and bumps CONTRACT_VERSION to (1, 25) so a 1.25 host accepts 1.25 and newer minors while 1.24 is rejected as incompatible. (crates/tinysecurity-bus/src/policy.rs pub struct ModuleConfig {, crates/tinysecurity-bus/src/policy.rs impl Default for ModuleConfig {, crates/tinysecurity-bus/tests/scoped_wire.rs fn new_members_are_advertised_and_named_by_contract_constants() {, crates/tinysecurity-bus/src/device_frame_tests.rs fn frame_operations_redact_both_payloads_without_changing_open_wire_shape())
• Modified — Native fixture multi-generation pairing exercise (mode 18): acquire_master becomes generation- and call-id-parameterized with an advancing audit sequence; configuration branches mode 18 with approval required and device/device_pairing slots populated; the fixture implements the pairing host callbacks, pause/notify hooks for load and store racing, and a mode-18 run path that raises the proxy timeout to 30 seconds and exercises unlock, legacy import, recovery, enrollment, frames, refresh, renewal, close, revoke, reinit and lost-confirm recovery. (crates/tinysecurity-module/examples/secret_cipher_native_contract/fixture.rs async fn acquire_master(proxy: &tinybus::Proxy, state: &State) -> tinybus::Resul, crates/tinysecurity-module/examples/secret_cipher_native_contract/fixture.rs fn configuration(, crates/tinysecurity-module/examples/secret_cipher_native_contract/fixture.rs impl Interface for Callback {)
• Modified — Native-entry rework to admit paired tunnels: Seal/Open on the new Native::PairedTunnel variant is denied alongside key handles, while frame execution and validation accept both tunnel kinds and revalidation checks the scope epoch. (crates/tinysecurity-crypto/src/device_handles.rs struct State {, crates/tinysecurity-crypto/src/device_handles.rs struct Scope {)
• 1 additional supported feature(s) omitted by the configured limit.

Tests

• owner state machine tests — Covers enrollment only after a possession proof and durable commit, invalid channel rejection before pending state, same-key renewal on a fresh socket, socket-close scoping, stale close fencing, refresh preserving tunnel keys and replay counters, restore/rejection of corrupt or foreign state, renewal channel collisions, oversized-revocation reservation denial, legacy import atomicity/idempotency with tombstone no-resurrect, revocation-stable per-channel identities across reload, and backend identifier bounds.: Present in the diff and directly asserted; no test execution is claimed by this summary. (crates/tinysecurity-crypto/src/device_pairing_tests.rs)
• registry lifecycle tests — Asserts paired-tunnel registration in the DeviceFrame2 registry, frame open through a paired handle, refresh extension, replay denial, retirement of single handles and whole scopes on logout, clock-rollback denial for paired-tunnel refresh, and that paired retirement leaves ordinary device handles intact.: Present in the diff; no test execution is claimed by this summary. (crates/tinysecurity-crypto/src/device_handles_tests.rs fn frame_revalidation_rejects_a_tunnel_after_generation_change() -> TestResult {)
• native cipher tests — Asserts the retained pairing cipher keeps plaintext inside the module with zero host delivery calls, rejects disabled encryption and plaintext persistence, outlives alias expiry, and is denied after a generation advance.: Present in the diff; the tests lane answered with no findings in its findings list, and no test execution is claimed here. (crates/tinysecurity-crypto/src/native_handles/cipher_tests.rs async fn disabled_plaintext_empty_and_legacy_replacements_use_confidential_deliv)
• contract serialization and versioning tests — Serde fixtures assert pairing requests carry only event ids/receipts and confidential bytes, reject caller-asserted scope fields, redact debug output for requests and responses, expose no key or authority claims for legacy import and recovery, echo fixed persistence bindings, pin the contract at 1.25, and verify the compatibility boundary where 1.24 is rejected.: Present in the diff; the tests lane noted one wire-contract test asserts RefreshSession/EndSession distinctness only through always-REDACTED Debug output, so no serialized kind is pinned for those variants; its findings list is empty. (crates/tinysecurity-bus/src/device_pairing_tests.rs, crates/tinysecurity-bus/tests/scoped_wire.rs fn new_members_are_advertised_and_named_by_contract_constants() {, crates/tinysecurity-bus/tests/wire.rs fn redactor_init_is_additive_and_secrets_never_enter_public_info())
• module adapter unit tests — Exercises adapter helpers around scope locking, agent denial before scope lookup, plaintext snapshot rejection, failed-refresh and clock-rollback tunnel retirement, canceled revoke/import/confirmation fencing, post-store validation fencing, expired logout-context denial, bounded backend identifiers, and queued handshake denial after an epoch change.: Present in the diff; the tests lane reported it was still reading the registry, tunnel and cipher paths, so these are not described as confirmed. (crates/tinysecurity-module/src/adapter_device_pairing_tests.rs, crates/tinysecurity-module/src/adapter_secret_tests.rs mod linked_fixture {)
