+//! F1/F2b: the Rust `client-runtime` hosted IN the app process, behind the
+//! `native-core` Cargo feature.
+//!
+//! With the feature off, this module is not compiled and the crate builds
+//! byte-identical to before — the WebView `src/core` keeps owning the Nostr
+//! sockets. With it on and the WebView opting in (`core_init`), the sockets +
+//! crypto + connection FSM + every store (F2b: over real SQLite persistence,
+//! `native_ports.rs`) run here, on a dedicated thread inside the
+//! stay-connected foreground service. The WebView receives the semantic
+//! `CoreEvent` stream + already-decoded bridge→phone messages over Tauri
+//! events, and drives user actions through `core_dispatch(Intent)` and the
+//! `core_*_view` queries (plan §2) — this is the full surface the re-point
+//! consumes, replacing `src/core`'s direct-socket path entirely.
+//!
+//! Threading: `client_runtime::Core` drives a `!Send` event loop
+//! (`Rc`-based, mirroring the TS `this` model), so it lives on this thread's
+//! `LocalSet`. The `Core` *handle* is `Send` (its only field is an mpsc sender
+//! of `Send` messages) and is handed back to Tauri's `State` for the commands
+//! to call.

-//! Marmot (MLS) DMs — CDX-012, plan §5b.
-//!
-//! MDK 0.8 (Marmot Development Kit, rust-nostr family — the same protocol
-//! stack as White Noise and the local yenn reference) does ALL the MLS crypto
-//! and group state in Rust, persisted in its own SQLCipher-encrypted SQLite
-//! file in the app data dir. JS owns transport: every command returns Nostr
-//! events as JSON for the webview to publish through the app's existing relay
-//! client, and the webview feeds received relay events back in via
-//! `marmot_ingest`.
-//!
-//! Wire model (MDK 0.8 / MIP-00, verified against the yenn reference):
-//!   • KeyPackages are ADDRESSABLE kind-30443 events (not 443), signed by the
-//!     real identity key, carrying a `d` tag.
-//!   • Welcomes are kind-444 rumors that ONLY travel gift-wrapped inside
-//!     kind-1059 wraps (a bare 444 on a relay leaks group membership); the
-//!     accept path needs the WRAPPER event id, not the rumor id.
-//!   • Group messages are kind-445 events signed by MLS-exporter-derived
-//!     ephemeral keys, routed by the `h` tag (hex `nostr_group_id`).
-//!
-//! Hard-won reference behaviors ported verbatim (do NOT invent MLS handling):
-//!   • VEIL-029 guard: NEVER hand a 445 for a not-yet-joined group to
-//!     `process_message` — MDK permanently poisons the event ("Failed" →
-//!     forever `Unprocessable`), and the creator's first message legitimately
-//!     races ahead of the welcome. Return `not_joined`; the JS side buffers
-//!     and re-feeds after the welcome is accepted.
-//!   • VEIL-117: accept EXACTLY the welcome `process_welcome` returned (keyed
-//!     by rumor id via `get_welcome`), never `get_pending_welcomes().first()`.
-//!   • VEIL-167: re-feeding an already-processed 445 can't re-decrypt (MLS
-//!     ratchet secrets are consumed) — serve the rumor MDK persisted on first
-//!     processing instead of surfacing the failure (idempotent re-feed).
-//!
-//! Secrets discipline: the identity secret and the derived DB key are never
-//! logged and never appear in error strings.

+//! request. Behind `native-core`, same as `corebridge.rs`.
+//!
+//! Reuses `tauri-plugin-http`'s OWN `reqwest` (re-exported as

+//! the dependency tree — the WebView path already depends on this exact

+//! dependency's comment in `Cargo.toml`); this is the same client, just
+//! driven directly from the core's own thread instead of round-tripping
+//! through the frontend.
+//!
+//! SOCKS5-aware: when the phone has Tor enabled, `core_init`'s `InitConfig`
+//! carries the SAME `host:port` the WS transport dials for the relay
+//! sockets — this client is built with the identical `reqwest::Proxy`, so a
+//! Blossom upload never bypasses Orbot while Tor is on (the repo's no-bypass
+//! rule applies here exactly as it does to the relay sockets). `set_proxy`
+//! rebuilds the client live when `Intent::SetTorEnabled` fires — `reqwest`
+//! bakes its proxy in at build time, so there is no in-place update, only a
+//! fresh client swapped into the same `RefCell` `put`/`get` already clone

- *
- *   pair via the real pairing window → session in a folder → live output lands
- *   in transcriptStore → input via the outbox reaches confirmed → bridge
- *   restart → phone FSM reconnect → refresh + sync gap-refill → contiguous
- *   transcript identical to the bridge's store.

- * the production tree under src/core never imports them (layering.test.ts
- * enforces that).

+ * Thin, hand-written facade over the generated bindings
+ * (`nativeCoreTypes.generated.ts`, produced by `apps/mobile/src-tauri/
+ * tests/gen_ts_bindings.rs` from client-runtime's `View`/`Intent`/`CoreEvent`
+ * Rust types — see that test's own doc comment, and never hand-edit the
+ * generated file itself).
+ *
+ * tauri-specta emits a `X_Serialize`/`X_Deserialize` pair (plus a
+ * `X = X_Serialize | X_Deserialize` union under the bare name) for any type
+ * whose dependency graph has a field that serializes and deserializes
+ * asymmetrically — chiefly anything downstream of a
+ * `#[serde(skip_serializing_if = ...)]` field, which several `protocol`
+ * leaf types (`OutputEntry`, `ProviderProfileWrite`, …) carry. Every one of
+ * these types crosses the wire in exactly ONE direction in this app: Views
+ * are Rust-serialized and never deserialized back; `Intent` is constructed
+ * here and deserialized Rust-side. Re-exporting the ambiguous two-phase
+ * union under the bare name would force every read site to redundantly
+ * narrow a case that can't actually occur (`intent.selectSession` would
+ * type as "possibly absent" even though, on the `Intent` this app
+ * constructs, a `selectSession` intent object always has it).
+ *
+ * This file changes no shape for the View/Intent/CoreEvent surface above —
+ * it only names which half of an already-generated pair is the one this app
+ * actually uses, the same way a human author would have picked a single
+ * direction by hand before generation existed.
+ *
+ * The `PhoneToBridge`/`BridgeToPhone` message unions below are a DIFFERENT
+ * case: `PhoneToBridge`/`BridgeToPhone` are internally tagged
+ * (`#[serde(tag = "type", rename_all = "kebab-case")]` — the real wire JSON
+ * is flat, `{"type":"input",...InputMsg fields}`, confirmed against
+ * `packages/protocol/fixtures/corpus.json`'s own fixtures), but specta's
+ * generated TS for that repr still nests each variant's payload under an
+ * extra key matching the variant name (`{ input: { type: "input", ... } }`)
+ * — confirmed directly: TypeScript accepts only the nested object literal
+ * for `PhoneToBridge_Deserialize`, and rejects the real flat shape outright.
+ * `crates/protocol`'s own inner message structs (`InputMsg`, `PairAckMsg`,
+ * …) don't have this problem — they're plain structs, not enum variants —
+ * so the union below is reconstructed from THOSE (each intersected with its
+ * own literal `type` tag) instead of from the generated
+ * `PhoneToBridge`/`BridgeToPhone` unions directly.

- *   unread is respected upstream: the DM store only reports messages that
- *   count unread (active conversation suppresses them).
- * - Sync catch-up entries never notify: only the LIVE output path classifies
- *   entries, so replaying history after a reconnect can't cause a storm.
- * - The OS side is a port (`Notifier` in ports.ts): Tauri's notification

+/**
+ * A native-backed `BridgeApiLike` (migration F2b) — the replacement for
+ * `BridgeApi` when the phone is fully re-pointed at the Rust core: every
+ * method dispatches the matching `Intent` instead of building, NIP-44
+ * encrypting, signing, and publishing the wire command itself (Rust already
+ * owns that whole pipeline, proven end to end this session's `Intent`
+ * additions and the Layer 2 contract-harness gate).
+ *
+ * `dispatch` here is optimistic — it resolves `true` once the Intent was
+ * accepted for processing, not once the bridge actually answered. This
+ * matches every other native adapter's "the next view refresh is the real
+ * state" contract, and is no different from what `BridgeApi.send` itself
+ * promises: `true` there means "a relay accepted the publish," never "the
+ * bridge processed it."
+ *
+ * `createFolder` dispatches `Intent::CreateFolder` with a fresh request id
+ * and races the matching `CoreEvent::FolderAck` against `timeoutMs` — the
+ * listener is registered BEFORE the dispatch (same ordering `hydrateFromCore`
+ * uses elsewhere), so a same-tick reply can never be lost to a late-attaching
+ * callback.
+ *
+ * Two methods stay deliberate, documented rejections rather than
+ * like-for-like shims:
+ * - `uploadImageBlossom`/`uploadImageChunk`: their two-stage shape (upload
+ *   raw bytes to Blossom, THEN separately publish the resulting hash/key
+ *   reference; or fall back to relay chunks) is already re-implemented as
+ *   ONE unconditional step inside `Intent::SendSessionImage` — the Rust
+ *   core does its own Blossom upload via the `HttpFetch` port and decides
+ *   the chunk fallback internally. Shimming these two callbacks
+ *   individually would either upload the image TWICE (once via the
+ *   existing TS `uploadToBlossom` helper the caller already ran, once more
+ *   inside the dispatched Intent) or silently swallow the fallback the
+ *   caller expects to invoke independently. Neither is an acceptable
+ *   "close enough": the native call site skips `sendSessionImage()`
+ *   (`apps/mobile/src/ui/imageFile.ts`) entirely and dispatches
+ *   `Intent::SendSessionImage` with the raw bytes directly — see
+ *   `PhoneCore.sendSessionImageNative` (`createPhoneCoreNative.ts`) and its
+ *   `SessionScreen.tsx` call site, a UI-level branch this backend shim
+ *   cannot paper over.

  *
- * ONE pure reducer consumes every connectivity signal (network online/offline,
- * page visibility, Tauri resume, socket open/close, heartbeats, decrypt
- * failures) and returns the next state plus a list of effects. The store is a
- * thin interpreter: it runs the effects against injected seams (socket client,
- * timers, refresh/reconcile), so every policy below is unit-testable on the
- * reducer alone:
- *
- * - A visibility flip is DEBOUNCED (500ms) and NEVER tears down a healthy
- *   socket — backgrounding the app briefly no longer causes a disconnect.
- * - Reconnects back off exponentially (2s → 30s cap) with +25% jitter.
- * - Every successful (re)connect triggers `refresh-and-reconcile`: send
- *   refresh-sessions (CDX-008 proved the boot 30515's seqHigh goes stale) and
- *   reconcile transcripts via the sync protocol.
- * - Decrypt failures increment a diagnostics counter and raise
- *   `needsPairingCheck` — they are NEVER treated as a lost connection (the old
- *   app faked disconnects out of them).
- * - Presence per machine is an honest 3-state f(30515 age, socket state):
- *   live / stale / offline — no since-filter staleness guessing.
- * - CDX-020: subscriptions can die WITHOUT the socket closing (no onclose is
- *   ever delivered; publishes keep working). The periodic sweep calls
- *   `checkHeartbeats()`: status `connected` while every machine heartbeat is
- *   stale → dispatch `socket-close` so the normal backoff/reconnect path runs
- *   and the UI chip tells the truth.
+ * The FSM itself — the pure reducer that decided backoff, visibility
+ * debounce, and presence — is ported to Rust
+ * (`client_core::connection::connection_reducer`, `client_runtime`'s own
+ * `presence_of`/`heartbeats_all_stale`) and driven by `client_runtime::Core`.
+ * `createNativeConnectionStore` only translates high-level `ConnectionEvent`s
+ * into `core.start()`/`stop()`/`setOnline()`/`pause()`/`resume()` calls; it
+ * does not re-implement the FSM. Only the shared TYPES survive here.

- * dmStore — NIP-17 direct messages, ported from the old app's dmStore +
- * nostrService (CDX-011 Phase 5b). DMs ONLY: the keypair lives in
- * identityStore and reaches this store through deps (plan §5); DM content is
- * standard Nostr (kind 14 rumor → kind 13 seal → kind 1059 gift wrap via
- * nostr-tools nip59) — deliberately protocol-independent, no @codedeck/protocol
- * schemas involved.
+ * NIP-17 DM types + the pure peer-input helpers, shared by the native
+ * adapter (`nativeDm.ts`) and the UI (`DmTile.tsx`, `DmSection.tsx`,
+ * `dm/DmChatScreen.tsx`, `dm/MarmotChatScreen.tsx`, `platform/profileFetch.ts`).
  *
- * Send path (ported): create the kind-14 rumor ONCE (deterministic rumor.id =
- * the message id for dedup), then seal+wrap twice — for the recipient AND for
- * ourselves (the self-copy is what makes our own messages survive a
- * reinstall/restart via relay catch-up) — and publish both through the app's
- * transport.
- *
- * Receive path: one dedicated kind-1059 subscription (own epoch guard, own
- * since-cursor: NIP-59 randomizes gift-wrap created_at up to 2 days into the
- * past, so catch-up subscribes from `latest known message − 48h`; the id +
- * content dedup absorbs the replays). Unwrap failures are COUNTED in
- * diagnostics and logged — never swallowed silently (the old processGiftWrap
- * bug, CD-001).
- *
- * Conversations are keyed by peer pubkey and carry `protocol: 'nip17'` — the
- * seam Phase 6 (Marmot) extends into a unified, per-protocol-tagged list.
+ * The gift-wrap send/receive path (rumor → seal → wrap, the dedicated 1059
+ * subscription with its own epoch guard and catch-up cursor, dedup, and
+ * persistence) is Rust's job now (`client_runtime::giftwrap`,
+ * `client_core::stores::dm`) — only the shared TYPES and the two pure
+ * formatters (`parsePeerInput`/`truncatePeerLabel`, which the UI calls
+ * directly for input validation and display) survive here.

  *
- * The heart is `mergeSessionList`, a pure function with the contract that kills
- * bug B's session-loss vector:
- * - sessions present in the incoming list are upserted (presence 'live', or
- *   'offline' when the list is a machineOffline shutdown publish)
- * - ABSENCE NEVER DELETES: a known session missing from the incoming list is
- *   kept and marked 'stale'
- * - removal happens ONLY via explicit `removedSessions` tombstones — or a user
- *   delete through `userRemoveSession`
- * - persistence serializes the FULL machine map — the persister structurally
- *   cannot truncate (the old app persisted a merged-short list, permanently
- *   losing sessions)
- *
- * Machines are keyed (deduped) by bridge pubkey — identity is the keypair; the

 /**
- * marmotStore — Marmot (MLS) DMs, CDX-012 (plan §5b, Phase 6).
+ * Marmot (MLS group chat) types shared by the native adapter
+ * (`nativeMarmot.ts`) and the UI (`DmTile.tsx`, `DmSection.tsx`,
+ * `dm/MarmotChatScreen.tsx`, `MainPanel.tsx`).
  *
- * Split of labor (per plan): MDK in Rust does ALL the MLS crypto + group state
- * (src-tauri/src/marmot.rs, its own encrypted SQLite store); this store owns
- * transport + presentation. Every outgoing event comes back from Rust as JSON
- * for the app's existing relay client to publish; every received relay event
- * is fed into Rust via the seam. The seam (`MarmotPlatform`) is a port defined
- * HERE so the core stays platform-free — platform/marmot.ts implements it over
- * the Tauri commands; tests fake it.
- *
- * Wire model (MDK 0.8 / MIP-00, follows the yenn reference — NOT kind 443):
- *   • KeyPackages: addressable kind-30443, signed by the identity key,
- *     published on the app relays; peers fetch by author to invite us.
- *   • Welcomes: kind-444 rumors gift-wrapped in kind-1059 — they arrive on the
- *     dm store's EXISTING 1059 subscription, which routes non-NIP-17 rumors
- *     here (`onWrappedRumor` seam). Never published bare.
- *   • Group messages: kind-445, signed by MLS-derived EPHEMERAL keys, routed
- *     by the `h` tag (hex nostr group id). This store runs its own 445
- *     subscription filtered on the h tags of our groups.
- *   • kind 10051: KeyPackage relay list (MIP-00), published beside the KP —
- *     same pattern as NIP-17's kind-10050.
- *
- * Reference-critical behavior (VEIL-029, enforced Rust-side, honored here):
- * a 445 for a not-yet-joined group returns `not_joined` — this store BUFFERS
- * those (the group creator's first message legitimately races the welcome) and
- * re-feeds them after the welcome is accepted.
- *
- * Conversations are MLS groups (1:1 = 2-person group). They surface in the
- * SAME conversation list as NIP-17 via `unifiedConversations` with
- * `protocol: 'marmot'`. Scope guard: 1:1 parity first — the data model
- * carries member lists, but no multi-member management UI this phase.
+ * The MDK/MLS engine itself, the kind-445 subscription lifecycle, the
+ * KeyPackage mint-once decision, and gift-wrap welcome routing are Rust's
+ * job now (`client_core::marmot_engine`, `client_runtime::marmot`,
+ * `client_runtime::Core`'s own start sequence) — only the shared TYPES and
+ * `unifiedConversations` (a pure formatter the UI calls directly to merge
+ * the DM + Marmot lists) survive here.

+/**
+ * A native-backed `ConnectionStore` (migration F2b) — the thinnest adapter of
+ * the set, because most of `ConnectionState` was never a UI-facing contract
+ * to begin with. Production UI reads exactly two fields (`status` and
+ * `needsPairingCheck` — confirmed by search: `Sidebar.tsx`, `SessionScreen.tsx`),
+ * which is precisely what the F1 `NativeCore.connectionStatus()`/
+ * `onConnection()` surface already provides — the connection FSM itself has
+ * been fully ported to `client_core::connection` since F1, so there is
+ * nothing left to read back beyond that.
+ *
+ * The remaining `ConnectionState` fields (`attempt`, `online`, `visible`,
+ * `hiddenPending`, `lastConnectedAt`, `decryptFailures`, `heartbeats`) are
+ * internal FSM bookkeeping the Rust reducer owns entirely now; they stay at
+ * inert placeholder values here purely so this adapter satisfies
+ * `ConnectionStoreState`'s type for any code still typed against it.
+ *
+ * `dispatch` forwards exactly the platform signals TS still originates
+ * (network connectivity, app visibility, an OS resume) to the matching F1
+ * `NativeCore` lifecycle method — the same one-to-one mapping
+ * `Core::pause`/`resume`/`set_online` already document Rust-side:
+ * `{ type: 'visibility', visible: false }` → `pause()`, `visible: true` →
+ * `resume()` (which itself dispatches BOTH `Visibility{true}` and `Resume`
+ * Rust-side, so a bare `{ type: 'resume' }` maps to the same call).
+ * `socket-open`/`socket-close`/`retry-due`/`heartbeat-received`/
+ * `decrypt-failure`/`visibility-settled` are all FSM-internal now — the
+ * transport driver and the Router raise them directly inside Rust, so
+ * dispatching them here would be redundant at best.

+ * disconnect.
+ *
+ * Profile resolution (`resolveProfile`/`resolveAllProfiles`, backing the
+ * `profiles`/`profileStatus` fields) is the one piece of `DmStoreState` this
+ * adapter does NOT delegate to Rust: `client-runtime` has no Intent or view
+ * for it yet (`client-core`'s `DmState` models the cache shape, but nothing
+ * wires a kind-0 fetch to it). Since a display-name lookup is metadata
+ * convenience, not wire protocol or crypto, this adapter keeps the exact
+ * same cache logic `dm.ts` has today — same TTL, same injected
+ * `ProfileFetcher` — as a small local slice layered on top of the
+ * Rust-backed conversation state, rather than leaving the DM screens
+ * permanently showing truncated pubkeys until that Rust surface exists.
+ *
+ * `retry` cannot remove the old failed row the way `dm.ts` does (native
+ * message state lives in Rust, and there is no "delete this DM message"
+ * Intent) — it re-dispatches `sendDm` with the same content and lets the

+ *
+ * Rust only re-announces state on an actual transition (see
+ * `client_runtime::Core::dispatch`'s own doc comment on `connection_status`/
+ * `*_view`: "a fresh read for a UI that just attached — the observer only
+ * reports changes"). It never replays history for a listener that attaches
+ * late, and Tauri's `listen()` has no buffering: an event emitted before a
+ * listener finishes attaching is lost for good.
+ *
+ * On an ordinary app reopen against an already-connected, already-populated
+ * core (the singleton `CoreBridge` — built once in `lib.rs`'s `run()` — is
+ * designed to outlive a WebView reload, and `core_init` is explicitly
+ * idempotent), nothing is about to transition again soon. That makes the
+ * one-shot snapshot fetch the ONLY chance to observe the real state — firing
+ * it unawaited alongside listener registration left the two racing with no
+ * guaranteed order, and a lost race (or a swallowed rejection) stranded the
+ * store at its construction-time default forever. This is the root cause
+ * behind the connection dot staying stale, and a bridge-confirmed session
+ * not appearing, after closing and reopening the app.
+ *
+ * Awaiting registration first closes THAT gap: once it resolves, any
+ * transition from that point on is guaranteed to arrive over the listener,
+ * and the fetch that follows reads whatever is true at that instant — no
+ * version/generation counter needed.
+ *
+ * It does not close a second, ongoing one: `corebridge.rs`'s `TauriObserver`
+ * discards every `app.emit(...)` result (`let _ = ...`), and Android can
+ * suspend a backgrounded WebView's JS execution for long enough that a push
+ * racing that window is silently dropped — mid-session, not just at boot,
+ * and with nothing left afterward to notice or retry it (Rust does not
+ * repeat an announcement once made). Re-pulling on every `onResume` closes
+ * this the same way the boot-time fetch closes the listener-registration
+ * race: never trust a push alone to have survived whatever the OS did while
+ * the app was backgrounded — re-read the truth once it's safe to.

+ *
+ * Two representational gaps between the TS and Rust sides, both resolved

+ * remembers it rather than needing the Rust view to carry it:
+ *
+ * - `beginPair`/`stagePair` take an ALREADY-PARSED `ParsedPairingUrl`, but
+ *   `Intent::BeginPairing`/`StagePairing` need the raw `codedeck://pair`
+ *   URL (the Rust store re-parses it itself, matching the TS parser's own
+ *   "spec"). `buildPairingUrl` reconstructs it — mirrors
+ *   `packages/core`'s pairing URL BUILDER byte for byte (relay/machine/
+ *   token/mesh params individually `encodeURIComponent`'d, `npub` raw).
+ * - The Rust `PairingView` reports `hasStaged: boolean`, not the staged
+ *   URL's parsed details the confirm screen displays — `stagePair`'s
+ *   caller already handed us the full `ParsedPairingUrl`, so it's cached
+ *   locally and shown until the view reports `hasStaged: false`.
+ *
+ * `PairingStoreState` has no pair-ack handler: the Rust `Router` folds a

+ * A native-backed `TranscriptStore` (migration F2b) — the one adapter backed
+ * by an async, I/O-driven view (`TranscriptRowsView`, SQLite-on-device via
+ * `TranscriptStore::read_range`) rather than a synchronous in-memory
+ * snapshot every other adapter reads.
+ *
+ * The Rust `Router` already applies every `Output`/`SyncBegin`/`SyncChunk`/
+ * `SyncEnd`/`CloseSessionAck` bridge message directly into the real,
+ * persistent `TranscriptStore` port, so `TranscriptStoreState` carries no
+ * ingest methods for those at all — there is nothing left in TS to drive
+ * them from. `ensureSynced`/`retrySweep` DO stay real (the sync-request
+ * button and the periodic connectivity-driven retry both still call them),
+ * but Rust runs its own sync-gap reconciliation on every session-list
+ * heartbeat regardless, so both are no-ops here too.
+ *
+ * `hydrateSession` is the one write-shaped method this adapter actually
+ * implements: it is how a caller says "I want this session's transcript
+ * resident" — `createPhoneCoreNative.ts` calls it for every known session
+ * at boot, and this adapter keeps that same contract, fetching a fresh
+ * `TranscriptRowsView` and caching it into `sessions`. After that, `session`/
+ * `entriesOf`/`haveRangesOf`/`hasContiguous` are synchronous reads over the
+ * cache, same as the TS store's own reads — correct as long as hydration
+ * (or a `CoreEvent::TranscriptAppended` refresh) has already populated the
+ * entry.
+ *
+ * `CoreEvent::TranscriptAppended { machine, sessionId }` re-fetches that
+ * session unconditionally (not gated on "is it selected") — matching the
+ * existing boot-time-hydrate-everything design, not a new eagerness this
+ * adapter introduces.
+ *
+ * `seqConflicts` and `activeSyncId` have no production reader anywhere in
+ * the UI (confirmed by search) — they stay `[]`/`null` rather than inventing
+ * a Rust surface nothing needs yet. `hasContiguous` mirrors `transcript.ts`'s
+ * own check (a single cached range starting at 1) rather than reaching for
+ * a Rust equivalent, since it is a pure function of `haveRanges`, which is
+ * already cached.

+/**
+ * A native-backed `UiStore` (migration F2b) — same family as the other
+ * native adapters: exposes the SAME `UiStoreState` shape `createUiStore`
+ * (`./ui.ts`) does, backed by a cached `NativeCore.uiView()` refreshed on
+ * the `ui` slice's `stateChanged` event.
+ *
+ * `UiView` mirrors `client-core`'s `UiState` verbatim — it is NOT the plan
+ * §2.1 `CardsView` (a different, larger, per-session projection of actual
+ * card CONTENT that lands with the transcript-view work). `UiState` only
+ * ever held the optimistic bookkeeping around cards, all of it flat and
+ * already fully ported, so it gets a thin view now rather than waiting on
+ * that bigger design.
+ *
+ * `markCardResponded` is a no-op: `Intent::RespondPermission` already marks
+ * the card responded Rust-side and sets `ui_changed`, so the next refresh
+ * picks this up on its own — the call site's own local mark just avoids a
+ * one-frame flicker back to "unresponded" while that refresh is in flight.
+ *
+ * `noteCredentialsSent`/`noteDeviceConfigSent`/`noteProviderProfileSent` set
+ * a local `state: 'saving'` entry the same way `setPlanApprovalChoice` sets
+ * its local choice: `Intent::SetCredentials`/`SetDeviceConfig`/
+ * `SetProviderProfile` are real and already dispatched by the call sites
+ * that call these (`MachineCredentials.tsx`, `MeshSection.tsx`,
+ * `MachineProviders.tsx`), but nothing marks "saving" while the round trip
+ * is in flight — without this, the button just looks unresponsive until the
+ * bridge's ack eventually lands and the next view refresh shows `saved`/
+ * `failed` out of nowhere.
+ *
+ * `selectSession`/`selectDmPeer`/`selectMarmotGroup`/`setPlanApprovalChoice`
+ * are the genuinely user-facing mutations and dispatch real Intents,
+ * optimistically updating the local cache first the same way
+ * `nativePairing.ts`'s `confirmStaged`/`reset` do.

- * Flow: parse URL (QR scan / pasted link) → beginPair sends a pair-request
- * carrying the one-time token → the bridge answers pair-ack → paired (machine
- * registered) or failed (bad-token / window-closed / timeout). Manual fallback:
- * the user types the bridge npub + token from the bridge's pairing screen.
+ * The pair-flow state machine itself (arm/disarm the CDX-040 ack deadline,
+ * merge relays the ack carried, the manual-npub fallback) is Rust's job now

- * Phase 3a scope: the relay list (manual add/remove — every component supports

- * stay-connected foreground-service toggle).
+ * Settings — shared types + the persisted-shape helpers `createNativeSettingsStore`

+ * The stateful local store this file used to also implement (`createSettingsStore`,

 /**
- * transcriptStore — per-session transcript persistence + the sync client.
+ * Transcript types shared by the native adapter (`nativeTranscript.ts`) and
+ * the UI (`coreContext.tsx`).
  *
- * Kills bug B ("session history gets lost") by design:
- * - Every entry goes through an async storage port with INSERT OR IGNORE
- *   semantics on (machine, session, seq) — dedup is structural, and Phase 3b
- *   swaps the in-memory port for SQLite without touching this store.
- * - `haveRanges` is computed from what is actually stored (via
- *   @codedeck/protocol's range math) — sync requests carry the truth, so gaps
- *   from missed ephemeral output are exactly what gets re-delivered.
- * - Per-session sync status with bounded attempts + exponential retry backoff
- *   REPLACES the old never-reset `autoHistoryRequested` Set: a failed sync
- *   retries after a backoff, and `onReconnect()` resets every cycle so a fresh
- *   connection always gets a fresh chance. One failed fetch can no longer
- *   blank a session forever.
- * - A seq arriving twice with different content is recorded in `seqConflicts`
- *   (bridge-side renumbering — forbidden by the contract) and NOT applied.
- *
- * All mutations run on one internal write queue so storage writes and the
- * reads that feed sync-requests never interleave; `flush()` awaits it (tests).
+ * Row persistence (INSERT-OR-IGNORE dedup on (machine, session, seq)), the
+ * sync client (haveRanges/missingRanges, bounded retry backoff, seq-conflict
+ * detection), and the write queue are Rust's job now
+ * (`client_core::stores::transcript`, `client_runtime`'s I/O-backed
+ * `TranscriptRowsView`) — only the shared TYPES survive here.

- * relayTransport — the real `PhoneTransport` over nostr-tools' SimplePool
- * (Phase 3b).
- *
- * Deliberately THIN: the connection-epoch guard, per-class filters, dedup and
- * FSM wiring all live in the core's `PhoneNostrClient` — this module only
- * adapts SimplePool's surface to the `PhoneTransport` port:
- * - `enablePing: true` (WS-level liveness — part of the bug-A fix; a dead
- *   socket is detected instead of silently rotting),
- * - `enableReconnect: false` — reconnect policy belongs to the connection FSM,
- *   not the pool; a dying subscription must surface as ONE `onClose` so the
- *   FSM can back off honestly,
- * - `idleTimeout` neutralized (CDX-020) — with `enablePing` on, nostr-tools
- *   2.24.1 closes the relay on its OWN timer a couple of minutes after every
- *   connect and takes every live REQ with it. See platform/poolOptions.ts for
- *   the full mechanism; the constant is shared with the bridge's fix (CDX-055),
- * - subscription `onclose` is forwarded ONLY for non-deliberate deaths: after
- *   `sub.close()` / `transport.close()` the transport never calls back (the
- *   nostr-tools "pool.destroy fires onclose" trap dies here AND in the
- *   client's epoch guard — belt and braces),
- * - `setRelays` replaces the list for future subscribe/publish calls (the
- *   client resubscribes right after),
- * - `publish` resolves true when at least one relay accepted the event.
- *
- * The pool is injectable (`PoolLike`) so subscription bookkeeping and close
- * idempotence are unit-tested without sockets; the real-socket smoke runs in
- * the device-test phases.

+//!   NIP-44 nonce, so the id changes, the bridge's id-based dedup cannot help,
+//!   and an image gets injected twice (CDX-086).
+//! * [`BridgeApi::ingest`] is total: a bad payload is a returned variant plus a
+//!   diagnostics bump, never a panic and never a fake disconnect. A NIP-44
+//!   decrypt failure from a known machine is reported to the connection FSM as a
+//!   diagnostic (`needsPairingCheck`), not a socket close.

+//! Connection FSM — kills bug A ("relay connection keeps dropping") by design.
+//! Pure port of the reducer half of `apps/mobile/src/core/stores/connection.ts`
+//! (the effect *interpreter* + store live in `client-runtime`).
+//!
+//! ONE pure reducer consumes every connectivity signal (network online/offline,
+//! visibility, resume, socket open/close, heartbeats, decrypt failures) and
+//! returns the next state plus a list of effects. Policy, verbatim from the TS:
+//!
+//! - A visibility flip is DEBOUNCED and NEVER tears down a healthy socket.
+//! - Reconnects back off exponentially (2s → 30s) with +25% jitter.
+//! - Every successful (re)connect triggers `RefreshAndReconcile`.
+//! - Decrypt failures increment a diagnostics counter and raise
+//!   `needs_pairing_check` — they are NEVER a lost connection.
+//! - Presence per machine is an honest `f(30515 age, socket state)`.
+//! - CDX-020: subscriptions can die WITHOUT the socket closing;
+//!   [`heartbeats_all_stale`] detects it so the caller can force a reconnect.

+//! `MarmotService::ingest_group_message` / `unwrap_welcome`.
+//!
+//!
+//! Wire model (MDK 0.8 / MIP-00, verified against the yenn reference):
+//!   • KeyPackages are ADDRESSABLE kind-30443 events (not 443), signed by the
+//!     real identity key, carrying a `d` tag.
+//!   • Welcomes are kind-444 rumors that ONLY travel gift-wrapped inside
+//!     kind-1059 wraps (a bare 444 on a relay leaks group membership); the
+//!     accept path needs the WRAPPER event id, not the rumor id.
+//!   • Group messages are kind-445 events signed by MLS-exporter-derived
+//!     ephemeral keys, routed by the `h` tag (hex `nostr_group_id`).
+//!
+//! Hard-won reference behaviors ported verbatim (do NOT invent MLS handling):
+//!   • VEIL-029 guard: NEVER hand a 445 for a not-yet-joined group to
+//!     `process_message` — MDK permanently poisons the event ("Failed" →
+//!     forever `Unprocessable`), and the creator's first message legitimately
+//!     races ahead of the welcome. Return `not_joined`; the JS side buffers
+//!     and re-feeds after the welcome is accepted.
+//!   • VEIL-117: accept EXACTLY the welcome `process_welcome` returned (keyed
+//!     by rumor id via `get_welcome`), never `get_pending_welcomes().first()`.
+//!   • VEIL-167: re-feeding an already-processed 445 can't re-decrypt (MLS
+//!     ratchet secrets are consumed) — serve the rumor MDK persisted on first
+//!     processing instead of surfacing the failure (idempotent re-feed).
+//!
+//! Secrets discipline: the identity secret and the derived DB key are never
+//! logged and never appear in error strings.

+//! `display_entries` — pure transform from the flat transcript (`seq` +
+//! `OutputEntry`) to grouped display items, one per rendered row. Port of
+//! `apps/mobile/src/ui/transcript/displayEntries.ts`, on the v10 wire entry
+//! vocabulary the bridge actually produces.
+//!
+//! - `text` role=user → user message bubble.
+//! - `text` role=assistant → assistant markdown, or absorbed into a tool group
+//!   when `display_hint` is `collapse`.
+//! - `text` special=plan → plan markdown (stays visible).
+//! - `tool_use` / `tool_result` / `progress` / `thinking` → collapsed
+//!   "N actions" group.
+//! - `system` special=plan_approval → plan approval card.
+//! - `system` special=ask_question → question card (grouped by `tool_use_id`
+//!   for a multi-question turn).
+//! - `system` special=permission_request → permission card.
+//! - `system` special=session_restart → lifecycle marker.
+//! - `error` → error row.
+//! - `system` init banner / token counts / result summaries / `stream_end`
+//!   markers → filtered out; the rest are status lines.
+//!
+//! CDX-085: `thinking` is folded into the action group and counted with the
+//! rest — a turn no longer renders as an alternating `Thinking` / `N actions`
+//! stack. A lone thinking step reads as "1 action". `diff` deliberately stays
+//! OUT: it flushes the group and renders standalone (the point of a diff card
+//! is to be seen).
+//!
+//! Answered-state detection: a `tool_result` whose `tool_use_id` matches a
+//! card's id means the card was resolved.

+//! `marmot` store — Marmot (MLS) group DMs (CDX-012, Phase 6). Port of the pure
+//! half of `apps/mobile/src/core/stores/marmot.ts`.
+//!
+//! Split of labour (plan §5b): the MDK engine in Rust (`client-runtime`, its own
+//! encrypted SQLite store) does ALL the MLS crypto + group state; this state
+//! machine owns transport bookkeeping + presentation. Every outgoing event
+//! comes back from the engine as JSON for the app relay client to publish;
+//! every received relay event is fed into the engine and its `MarmotIngested`
+//! result applied here.
+//!
+//! Wire model (MDK 0.8 / MIP-00, the yenn reference — NOT kind 443):
+//! - KeyPackages: addressable kind-30443, identity-signed, on the app relays.
+//! - Welcomes: kind-444 rumors gift-wrapped in kind-1059 — they arrive on the
+//!   `dm` store's 1059 subscription, which routes non-NIP-17 rumors here.
+//! - Group messages: kind-445, routed by the `h` tag (hex group id).
+//! - kind-10051: KeyPackage relay list (MIP-00), beside the KP.
+//!
+//! VEIL-029: a 445 for a not-yet-joined group returns `not_joined` — those are
+//! BUFFERED (the group creator's first message races the welcome) and re-fed
+//! after the welcome is accepted.

+//! `pending_sessions` store — the phone side of two-phase session creation.
+//! Port of the pure half of `apps/mobile/src/core/stores/pendingSessions.ts`.
+//!
+//! The bridge publishes `session-pending` immediately on `create-session`, then
+//! either `session-ready` (→ the session appears as a real session and the
+//! placeholder is resolved) or `session-failed` (→ the placeholder flips to a
+//! visible error card). Keeping the optimistic placeholders here lets the
+//! sessions screen show "starting…" instantly and an honest error on failure.
+//!
+//! Not persisted: a placeholder that never resolves is meaningless after a
+//! restart (the bridge's registry is the real list). `sweep` drops the ones the
+//! bridge never answered (both the ready and failed events expired).

+//! `apps/mobile/src/core/stores/transcript.ts` (the storage port + the single
+//! write queue are the runtime's).
+//!
+//! Kills bug B by design:
+//! - `have_ranges` is computed from what is actually stored — a `sync-request`
+//!   carries the truth, so exactly the gaps get re-delivered.
+//! - Per-session bounded attempts + exponential retry backoff REPLACE the old
+//!   never-reset `autoHistoryRequested` set: a failed sync retries after a
+//!   backoff, and [`TranscriptState::on_reconnect`] resets every cycle so a
+//!   fresh connection always gets a fresh chance.
+//! - A seq re-arriving with different content is a recorded `seq_conflict`
+//!   (forbidden bridge-side renumbering) and NOT applied — the runtime computes
+//!   that from the storage rows and passes it in.

+//!
+//! Transient by design — none of this is persisted. A fresh boot starts with no
+//! stale unread dots, no stale "saved" credential claims, no undo toast.
+//!
+//! The two runtime seams (`onSessionViewed` / `onDmOpened`, CDX-026c: cancel a

+//! [`UiEffect`]s here; `visible` (the debounced app-visibility the connection

+//! The relay read-loop logic, pure. [`super::WsTransport`] owns N relay sockets

+//! * `on_event` fires per received event (no dedup here).
+//! * `on_eose` fires **once**, when every REQ'd relay still connected has sent
+//!   EOSE — matching nostr-tools `subscribeMany` (EOSE = "stored events are in
+//!   from all relays"), so the connection FSM's socket-open is honest.
+//! * `on_close` fires **once**, only when the subscription is dead on *every*

+//! `WsTransport` — the real [`Transport`] over WebSockets: one connect + read
+//! task per relay, wired through the pure [`frames`](super::frames) codec and
+//! [`router`](super::router).
+//!
+//! Single-threaded by construction. The [`SubCallbacks`] closures
+//! `nostr_client` hands us are `!Send`, so the whole transport runs on a
+//! current-thread runtime inside a `LocalSet` (the FG service's client thread);
+//! every task is `spawn_local`. This mirrors the TS `this`-bound model exactly.
+//!
+//! What lives here and NOT in a relay-pool crate (see docs/CLIENT-CORE.md):
+//! * **no auto-reconnect** — a dead socket surfaces as ONE `on_close`; the
+//!   connection FSM owns backoff and calls [`WsTransport::ensure_connected`].
+//! * **ping liveness** — a socket with no traffic for [`DEAD_AFTER`] is dropped
+//!   so a silently-rotted relay is detected, not trusted.
+//! * **NIP-42 AUTH** answered with the identity key; a `CLOSED: auth-required`
+//!   re-sends that subscription's REQ once AUTH is in.
+//! * **`publish_confirmed`** keeps the CDX-086 four-way verdict end to end.

+//! Views — the read-only, per-capability projections the bindings serialize
+//! and hand to the UI (migration plan §2.1). Plain serde data, sliced so a
+//! consumer subscribes only to what it paints.
+//!
+//! The store `*State` structs were designed as the serde wire shape, so the
+//! machines / outbox / settings views are thin newtypes over their public
+//! sub-state. `connection` is FSM-backed (the loop passes it in); `pairing`
+//! has no `Serialize` and is projected by hand. `TranscriptRowsView` is the
+//! one view backed by a port (`TranscriptStore`, SQLite on device) rather
+//! than a synchronous in-memory snapshot, so it alone needs I/O to build.
+//! The interaction-card *content* view (plan §2.1's `CardsView`, distinct
+//! from `UiView`'s optimistic bookkeeping) still has no home yet.

+//! F2b Layer 2 Go/No-Go gate (migration plan §4): drives the REAL
+//! `client_runtime::Core` against `tools/contract-harness` — a real
+//! `BridgeCore` + `FakeSdkFacade` reachable over a genuine `ws://` socket.
+//! Process + socket, no FFI shim.
+//!
+//! Ignored by default: it needs Node and the harness's own build. From the
+//! repo root:
+//!
+//!   cd tools/contract-harness && pnpm install && pnpm build
+//!   cargo test -p client-runtime --test contract_harness -- --ignored
+//!
+//! Scenario (the plan's Scenario A in full):
+//!
+//!   pairing window → session in the bridge's default folder → live output
+//!   lands in the transcript store → input via the outbox reaches confirmed
+//!   → bridge restart (resume-on-boot, a FRESH `FakeSdkFacade`) → the
+//!   phone's own connectivity drops and comes back → the FSM reconnects on
+//!   its own → sync gap-refill catches the phone up → the phone's
+//!   transcript is byte-identical to the bridge's own, seq for seq.

+# `client-core` / `client-runtime` — the shared Rust client
+
+Status: **F2b complete — the stop-point** (migration plan). The Node/TS side
+(`packages/*`, `apps/bridge`) is unaffected. `apps/mobile/src-tauri`'s
+`native-core` feature is now the **default** (field-tested on a real device;
+see the port-tracking table's last rows) and exposes the full plan §2
+View/Intent/CoreEvent surface as Tauri commands over real SQLite persistence
+and every `CorePorts` real: OS notifications (with working CDX-026c
+cancellation), Blossom HTTP, and Marmot/MLS — `NoMarmot` is no longer
+reachable from a default build. `apps/mobile/src/core` — the pre-F2b,
+WebView-driven local composition (`createPhoneCore.ts`, the local FSM/
+persistence half of every store, `services/nostrClient.ts`,
+`platform/relayTransport.ts`, `deleteController.ts`, `notifications.ts`,
+`selectionPersistence.ts`, `defaultSessionMode.ts`) is **deleted** (see git
+history on `claude/native-android`) — `createPhoneCoreNative.ts`
+(`apps/mobile/src/core/createPhoneCoreNative.ts`, eleven `stores/native*.ts`
+adapters + `services/nativeBridgeApi.ts`) is the sole `PhoneCore` composition
+now, and `main.tsx` fails loudly at boot rather than falling back to a local
+path if a Tauri build somehow lacks the feature — there is no fallback left
+to fall back to. Plain-browser dev (`pnpm dev` without Tauri) no longer boots
+the app at all; UI iteration requires a Tauri build. Every UI test that used
+to fixture itself against the local composition (~20 files) was migrated to
+a shared fake-`NativeCore` helper
+(`apps/mobile/src/core/__tests__/nativeCoreFixture.ts`) instead. All three
+gaps this pass originally found — plus three more (`Notifier`/cancellation,
+`HttpFetch`, `Marmot`) it surfaced along the way — are closed:
+`Intent::RemoveMachine`, the `main.tsx` capability check, `SessionScreen.tsx`'s
+native image-send branch (`PhoneCore.sendSessionImageNative`),
+`TauriNotifier`, `ReqwestHttpFetch`, and `MarmotEngineImpl`. Verified end to
+end: a real `native-core` benchmark APK builds, installs, and pairs on a real
+device — that pass also surfaced and fixed one more bug (the undo toast never
+clearing itself once its window expired, see the port-tracking table). Two
+things touched along the way were originally recorded as separate, known
+gaps rather than fixed in that pass — both later closed (see the
+port-tracking table): the Tor toggle now hot-reconfigures a running
+native-core transport and HTTP client live (`WsTransport::set_proxy`,
+`ReqwestHttpFetch::set_proxy`), and the attention chime (`ping`) now has a
+`CoreEvent::Ping` seam the WebView plays `platform/pingSound.ts`'s tone
+through — the pure `decide_ping` logic already existed, the router just never
+enabled it (`Router::new`'s `ping_available` default was never overridden).
+One-QR mesh auto-join (`Intent`'s `mesh_join`) still has no platform port
+wired for native-core — expected this early, since mesh is its own F6 Kotlin
+phase in the plan, not an F2b concern. `platform/torProxy.ts` (the
+WebView `PROXY_OVERRIDE` toggle) and its Tauri plugin (`tauri-plugin-tor-proxy`)
+had become dead code with no remaining call site once native-core started
+dialing its own SOCKS5 directly — both are now deleted; the `torProxyEnabled`
+setting and its Settings toggle stay, since they still drive `CoreConfig.proxy`/
+`tor` at `core_init`.
+
+## Why
+
+The "hard" client code — protocol codec, NIP-44, the connection FSM, the sync
+client, dedup/epoch guards, tombstone merge, outbox, pairing FSM, chunking,
+DM/Marmot orchestration, notification decisions — has identical requirements on
+Android and a future Desktop client. Duplicating it (Kotlin + TS) means doing
+every protocol change and every sync fix twice. It moves **once**, to Rust, and
+both clients consume it: Android via UniFFI, Desktop via `#[tauri::command]`.
+
+## Two crates
+
+| Crate | Contents | Rule |
+|---|---|---|
+| **`crates/client-core`** | protocol codec + schemas, `crypto`, reducers (`connection`, transcript pin, mode…), `ranges`, `chunking` (framing), stores as pure state machines, `sync` policy, `mergeSessionList`, `outbox` logic, `pairing` FSM, `presentation` model (`displayEntries`, `gsdStages`), notification decision engine. | **No `tokio`, no sockets, no threads, no I/O.** Clock/entropy injected. Deterministic. Every part covered by native vector tests. |
+| **`crates/client-runtime`** | tokio reactor, the `Transport` driver, live `ChunkAssembler`, `nostr_client` (epoch guard, dedup, cursor), lifecycle (`start`/`stop`/`pause`/`resume`), all ports wired. Exposes the `Core` handle. | The bindings (UniFFI, `#[tauri::command]`) attach **here**. `client-core` never knows a phone exists. |
+
+`apps/mobile/src-tauri` + its `tauri-plugin-*` crates keep their own build and
+are **not** workspace members yet — they join when `apps/android` is built.
+
+## The API surface (`client-runtime`, target shape — plan §2)
+
+- `*_view()` — read-only, plain-data projections by capability: `connection`,
+  `machines`, `transcript(id)`, `outbox`, `cards(id)`, `settings`, `pairing`,
+  `dm` (feat), `marmot` (feat). A consumer subscribes to the slices it paints.
+- `dispatch(Intent)` — one flat closed enum, ~30 variants, one per user action.
+  Total; returns `Result<(), CoreError>`. **Zero platform types** (images cross
+  as `bytes + mime`).
+- `subscribe(listener)` — a small closed `CoreEvent` stream: `StateChanged
+  { slice }`, `TranscriptAppended { session, from_seq }`, `PairingSettled`,
+  `OutboxSettled`, `ActionFailed { kind }`. **No UI strings.**
+- Ports (traits): `Kv`, `SecureStore`, `Transport` (WS + SOCKS5),
+  `TranscriptStore`, `Timers`, `Clock`, `Entropy`, `Notifier`, `HttpFetch`.
+
+Size budget: 1 handle + ~9 views + ~30 `Intent` + ~5 `CoreEvent` + ~9 ports.
+The API is **stabilised** with the mobile app (F2), **refined** by the first
+Compose screen (F3), declared stable after F3, additive thereafter.
+
+## What stays OUT (in each UI, correctly different)
+
+Navigation/layout, gestures/scroll physics, list virtualization, Markdown /
+syntax-highlight / diff / card **rendering** (the core gives the model), theming
+& scale, keyboard shortcuts, localized date/number formatting, OS file/image
+pickers, tray/menus.
+
+## Conventions (from the F0 probes)
+
+- A fielded UniFFI error variant must **not** name a field `message` (collides
+  with Kotlin `Throwable.message`; the 0.28 codegen emits no `override`). Use
+  `detail` / `reason`.
+- A `#[tauri::command]` lives in a submodule, never a library crate root (its
+  `#[macro_export]` collides with its own re-export there).
+- Wire enums are never modelled exhaustively at the boundary — `#[serde(other)]`
+  catch-all, so a newer Bridge's new enum value deserializes instead of failing
+  the message.
+- `Tristate<T> { Keep, Clear, Set(T) }` for the wire's absent/null/value cases
+  (e.g. `set-provider-profile`).
+- Leaning on the `nostr` crate (0.44, minimal features) for NIP-44 / NIP-42 /
+  event signing is fine — the only heavy transitive is `secp256k1` (C),
+  unavoidable.
+- The relay transport is **hand-rolled** on `tokio-tungstenite` + `tokio-socks`,
+  not `nostr-sdk` / `nostr-relay-pool`. The port's shape is a thin transport
+  *under* the connection FSM; a pool re-introduces the self-timed idle close
+  (CDX-020) and the "pool fires its own onclose" trap (CDB-037) the TS spent
+  effort defeating, and its publish result collapses `unconfirmed` vs
+  `unreachable` — the one distinction CDX-086 exists to keep. The client Nostr
+  wire is ~10 frame shapes (`client_runtime::transport::frames`).
+- `wss://` uses `rustls` (webpki roots), not `native-tls`, so it cross-compiles
+  for Android without OpenSSL. That pulls `ring` (C/asm) — one more heavy
+  transitive alongside `secp256k1`; the F1 `.so`-size gate (≤ 50 MB) covers it.
+- `WsTransport` is single-threaded: the `SubCallbacks` closures are `!Send`, so
+  it runs on a current-thread runtime inside a `LocalSet` (the FG service's
+  client thread), every task `spawn_local`. Mirrors the TS `this`-bound model.
+- The transport never reconnects on its own (`enableReconnect: false`) — a dead
+  socket is ONE `on_close`; the FSM owns backoff and calls
+  `WsTransport::ensure_connected`. `publish_confirmed` retries the SAME signed
+  event only on `unreachable` (transient); `rejected` from every relay will
+  reject it identically, `accepted`/`unconfirmed` mean the bridge has it.
+
+## Anti-drift with `packages/protocol`
+
+`packages/protocol` stays the **normative spec** (zod). The Rust `wire` codec
+is a mirror. `packages/protocol/fixtures/corpus.json` is the executable
+contract: `packages/protocol/src/__tests__/fixtures.test.ts` (vitest) and
+`crates/client-core/tests/codec_conformance.rs` (cargo) run the identical
+assertions — decode every `valid` entry + semantic round-trip, reject every
+`rejected` entry, ignore extra fields on `forwardCompatible` — on the identical
+bytes. A schema change mirrored on only one side fails CI there. The `cargo`
+job's `core` path filter includes `packages/protocol/fixtures/**`.

Known F1 rough edge: WebView + Rust both run a reconnect/CDX-020 loop — Rust is authoritative, the WebView's is a harmless nudge (F2: WebView store becomes a pure mirror in native mode). **`.so` ≤ 50 MB gate: PASS** — `./codedeck apk benchmark --features native-core` cross-compiles `client-core`/`client-runtime`/`tokio-tungstenite`/`tokio-socks`/`tokio-rustls` for `aarch64-linux-android` clean; `libcodedeck_mobile_lib.so` = 34.1 MB (≈ baseline — `ring`/rustls/tokio were already pulled by `reqwest`). **Still owed: emulator/real-device background matrix with the real transport, then delete the TS network path.** |
+| `machines` store (whole pure module) | `apps/mobile/src/core/stores/machines.ts` | `client_core::stores::machines` | ✅ F2a — `merge_session_list` (bug-B: absence never deletes, tombstones only, `machineOffline`, stale grace, title guard, per-session extras survive) + `MachinesState` transforms (`apply_session_list` with the CDX-022 spread + resurrection shield, `apply_models` CDX-035 dance, `apply_session_upsert`/`_replaced`, `note_first_user_message`, `user_remove_session`, `dismiss`/`restore`, `apply_usage`/`_gsd`/`_provider_profiles`) + `serialize_machines`/`hydrate_machines` (round-trip can never truncate; `providerProfiles` never persisted). 27 tests incl. the 200×30 property run. Runtime owns `set`/persist. |
+| `outbox` store | `apps/mobile/src/core/stores/outbox.ts` | `client_core::stores::outbox` | ✅ F2a — `OutboxState` send lifecycle (`new_input`/`begin_publish`/`settle_publish` verdict-wins/`confirm`/`fail`/`mark_retry`/`sweep`), CDX-013 retention (evict oldest resolved), `serialize`/`hydrate` total. 13 tests. |
+| `pairing` store | `apps/mobile/src/core/stores/pairing.ts` | `client_core::stores::pairing` | ✅ F2a — `parse_pairing_url` (strict decode, relay cap CDX-013) + `parse_manual_pair` + `pairing_reducer` FSM with `PairingEffect`s (CDX-028/040/041). 26 tests. |
+| `transcript`/`sync` store | `apps/mobile/src/core/stores/transcript.ts` | `client_core::stores::transcript` | ✅ F2a — `TranscriptState` sync client (coverage from storage, not a row cache), bounded backoff, `seq_conflicts`, `on_reconnect` reset, `SyncEffect`s. bug-B killer. 14 tests. |
+| `settings` store | `apps/mobile/src/core/stores/settings.ts` | `client_core::stores::settings` + `wire::relays` | ✅ F2a — `SettingsData` + tolerant `hydrate_settings` (CDX-021/042 legacy-default lift), relay dedup → `RelaysChanged` effect, clamped `ui_scale`. 8 tests. |
+| `pendingSessions` store | `apps/mobile/src/core/stores/pendingSessions.ts` | `client_core::stores::pending_sessions` | ✅ F2a — two-phase create placeholders (`apply_pending`/`resolve`/`apply_failed` ghost-safe/`dismiss`/`sweep` stale-`Pending`-only), `pending_for` oldest-first. Not persisted. 7 tests. |
+| `quickPrompts` store | `apps/mobile/src/core/stores/quickPrompts.ts` | `client_core::stores::quick_prompts` | ✅ F2a (CDX-049) — CRUD with trim + empty-field rejection, garbage-tolerant `hydrate_quick_prompts`, `serialize` round-trip; runtime owns id gen + KV. 3 tests. |
+| `notifications` decision engine | `apps/mobile/src/core/{notifications,notificationsCoordinator}.ts` | `client_core::notifications` | ✅ F2a — `decide_notify`/`decide_ping`, `NotificationCoordinator` shared cooldown, `classify_output_entry`, CDX-026c tags / CDX-048 toggle / CDX-053. 11 tests. |
+| mode / default-mode controllers | `apps/mobile/src/core/{modeCycle,defaultSessionMode}.ts` | `client_core::{mode_cycle,default_session_mode}` | ✅ F2a — `ModeCycle` FSM with `ModeCycleEffect` revert-timer seam (CDX-046), `DefaultModeApplier` once-per-session (CDX-047). 7 tests. |
+| `deleteController` | `apps/mobile/src/core/deleteController.ts` | `client_core::delete_controller` | ✅ F2a — pure `DeleteController` FSM: `request_delete`/`undo`/`timer_fired` emit `DeleteEffect`s (dismiss+remove+clear-unread+deselect / arm+toast / one `SendCloseSession` per committed delete, second delete commits the first). Undo restores the exact snapshot. 6 tests. |
+| `selectionPersistence` (CDX-054) | `apps/mobile/src/core/selectionPersistence.ts` | `client_core::selection_persistence` | ✅ F2a — `encode`/`decode_selection` tolerant, `is_restorable` bounded both sides (a future-stamped record from a backward RTC correction is not fresh). Runtime owns the KV + timestamp refresh. 3 tests. |
+| `sessionNeedsAttention` | `apps/mobile/src/core/sessionNeedsAttention.ts` | `client_core::session_needs_attention` | ✅ F2a — the one attention predicate (waiting-on-user OR unread), waiting branch independent of unread. 3 tests. |
+| `ui` store | `apps/mobile/src/core/stores/ui.ts` | `client_core::stores::ui` | ✅ F2a — `UiState`: selection + `panel_mode`, `unread_sessions` (visible-gated clear on select), `responded_cards`/`plan_approval_choices` (optimistic), the credentials / device-config / provider-profile ack slices, `undo_toast`. CDX-026c `onSessionViewed`/`onDmOpened` are `UiEffect`s; `visible` passed per call. All transient. 9 tests. |
+| `identity` store | `apps/mobile/src/core/stores/identity.ts` | `client_core::stores::identity` | ✅ F2a — `load_or_create_identity` (reuse a valid stored hex secret / regenerate on absent or corrupt, `needs_persist` flag for the runtime) + `IdentityState` holder. KV read/write is the runtime's. 3 tests. |
+| `gsdStages` | `apps/mobile/src/ui/gsd/gsdStages.ts` | `client_core::presentation::gsd_stages` | ✅ F2a — `phase_stages` (disk-status → Discuss/Plan/Execute triple + the reachable-action fallback), `strip_summary` (drops unresolved parts), `situation_label`, `recommended_action` (id → flag → first), `execution_line`, `recovery_chips`. Pure over the v10 `GsdState`. 5 tests. |
+| `displayEntries` | `apps/mobile/src/ui/transcript/displayEntries.ts` | `client_core::presentation::display_entries` | ✅ F2a — `build_display_entries` (flat `seq`+`OutputEntry` → grouped rows: user/assistant/tool_group/diff/error/system/lifecycle/plan_approval/question(_group)/permission_request), CDX-085 thinking folded into the action group, CDX-050 diff standalone, answered-card detection via `tool_result` match, `is_hidden_system_entry` noise filter, `find_pending_permission` (latest unanswered, un-responded). 15 tests. |
+| `imageChunks` (CDX-029) | `apps/mobile/src/core/imageChunks.ts` | `client_core::image_chunks` | ✅ F2a — `chunk_base64` (35 KB relay-safe pieces, lossless), `base64_to_bytes` (Blossom upload input), `blossom_hash_from_url`. Pure; the inter-chunk publish delay is the runtime's. Adds `base64` (already in the workspace tree via `nostr`). 5 tests. |
+| `dmAttachments` parse/build half | `apps/mobile/src/core/dmAttachments.ts` | `client_core::dm_attachments` | ✅ F2a — `parse_dm_content` (line-based text / `image` / `imageUrl` split, malformed refs stay text), `build_image_ref`, `preview_text`. The AES-256-GCM crypto + BUD-02 signed upload + download stay for `client-runtime` (need `aes-gcm` + `HttpFetch` port + deadline/abort). 6 tests. |
+| `dm` store (state machine) | `apps/mobile/src/core/stores/dm.ts` | `client_core::stores::dm` | ✅ F2a — `DmState`: structural dedup (`id` then sender+content window), conversation upsert + unread accounting (active conversation never counts), `ingest_dm_rumor` (self-copy peer via `p` tag, status), `dm_since_cursor` (newest − 48 h), `parse_peer_input` / `truncate_peer_label` / `ordered_conversations` / `build_dm_filter`, profile cache TTL, `hydrate_dm` tolerant. The `nip59` unwrap, transport sub + epoch guard, 10050 publish and profile fetch stay in `client-runtime` (that layer carries the `dm` feature gate — the pure state machine is dep-free). 14 tests. |
+| `marmot` store (state machine) | `apps/mobile/src/core/stores/marmot.ts` | `client_core::stores::marmot` | ✅ F2a — `MarmotState`: id-only dedup with the Failed→Sent promotion on the relay echo, conversation upsert (known-peer / prior-activity preference), unread gating, `apply_welcome` (stage + CDX-030 KP-consumed flag), `on_welcome_accepted` (join + welcomer backfill + returns the h tag), the VEIL-029 bounded unjoined-445 buffer + `take_buffered_for`, `should_mint_key_package` (CDX-030 mint-once), `unified_conversations` (Phase 6 list), `marmot_since_cursor`, `peer_of_group`, tolerant `hydrate_marmot`. The MDK/MLS engine calls, transport sub + epoch guard, KP + 10051 publish stay in `client-runtime` (that layer carries the `marmot` feature gate). 13 tests. |
+| `deadline` (cancel / budget / with_deadline) | `apps/mobile/src/core/deadline.ts` | `client_runtime::deadline` | ✅ F2b — `remaining_budget`, `with_deadline` (tokio timeout), `CancellationToken` cancel, `StageError` taxonomy. |
+| runtime ports | `apps/mobile/src/core/ports.ts` | `client_runtime::ports` | ✅ F2b — `Kv` / `TranscriptStore` / `Notifier` traits + `MemoryKv` / `MemoryTranscriptStore` / `RecordingNotifier`. `Clock` / `Entropy` in `rt::core`. `HttpFetch` in `rt::attachments`. |
+| store bundle + persistence | `apps/mobile/src/core/createPhoneCore.ts` (hydrate) | `client_runtime::stores` | ✅ F2b — `CoreStores` (every `client_core` state machine), `hydrate` (KV + transcript-coverage rehydrate + identity), `Persister`. |
+| message routing (`bridgeApi.handlers`) | `apps/mobile/src/core/createPhoneCore.ts` handlers | `client_runtime::dispatch::Router` | ✅ F2b — every `BridgeToPhone` family → `RouteResult` (persist / sends / notifies / heartbeat / pair-deadline / resubscribe). |
+| read projections | `apps/mobile/src/core` selectors | `client_runtime::view` | ✅ F2b — `Connection` / `Machines` / `Outbox` / `Settings` / `Pairing` / `Dm` / `TranscriptSync` + `Core::*_view()`. |
+| user actions | scattered store methods | `client_runtime::intent` | ✅ F2b — `Intent` enum + `apply` (session cmds, outbox send/retry lifecycle, delete + undo, full pairing flow, DM send/start, settings). `Core::dispatch(Intent)`. |
+| semantic event stream | store subscriptions | `client_runtime::core::CoreEvent` | ✅ F2b — `StateChanged{slice}` / `OutboxSettled` / `PairingSettled` / `ActionFailed` via `CoreObserver::on_event`. |
+| composed `Core` loop | `createPhoneCore.ts` | `client_runtime::core::Core` | ✅ F2b — async `spawn` (hydrate), Router + Intent + View + CoreEvent on one event loop; retry / vis / stale / pair / undo timers. |
+| NIP-17 DM runtime | `nostrService` DM path + `dmStore` I/O | `client_runtime::core` (1059 sub) + `client_runtime::giftwrap` | ✅ F2b — kind-1059 subscription (epoch + catch-up cursor + kind-10050 publish), `wrap_dm` / `unwrap_gift_parts` (NIP-59), `Intent::SendDm`, `DmReceived` notification. |
+| `dmAttachments` crypto / upload | `apps/mobile/src/core/dmAttachments.ts` | `client_runtime::attachments` | ✅ F2b — AES-256-GCM blob + SHA-256 id, `HttpFetch` port, BUD-02 signed upload with a retry budget, download+decrypt. |
+| Session image upload (CDX-029, Blossom + chunk fallback) | `apps/mobile/src/ui/imageFile.ts` `sendSessionImage` | `client_runtime::core` (`send_session_image`) | ✅ F2b — `Intent::SendSessionImage(SessionImageSend { machine, session_id, text, image, filename, mime_type })` (bytes + mime, no platform type, plan §2.2). Two independent stages, same shape as the TS port: stage 1 uploads to Blossom (`attachments::upload_encrypted_image`); on success stage 2 publishes `upload-image` Blossom and returns — a rejection there is a hard failure (the bytes are already on the server, so no chunk retry). On a stage-1 failure only, stage 3 falls back to `client_core::image_chunks::chunk_base64` (35 KB pieces, 200 ms inter-chunk delay, ≤200 chunks, 55 s chunk-assembly budget paired with the bridge's window, 120 s overall) publishing one `upload-image` Chunk command per piece at a single publish attempt each. No outbox item, no local echo — the image lands in the transcript once the bridge injects it, like any other output; any unresolved failure surfaces as `ActionFailed::PublishRejected`. |
+| Marmot runtime (445 sub, 444-welcome route, MDK seam) | `dmStore`/`marmotStore` I/O | `client_runtime::core` + `client_runtime::marmot` | ✅ F2b — `MarmotEngine` port (`NoMarmot` stub / `MarmotEngineImpl` behind feat `marmot`) in `CorePorts`. On (re)connect `Core` runs the full start sequence (mirrors `marmotStore.start()`): engine `init` → reconcile joined groups from `list_groups` → apply pending welcomes → CDX-030 mint-once KeyPackage + publish + the kind-10051 KP relay list → open the kind-445 subscription over the joined groups' `h` tags (epoch guard + catch-up cursor, torn down when no group is joined or the engine is absent). Each 445 goes through `marmot_engine.ingest`: a decrypted kind-9 rumor folds into `MarmotState` (unread + `DmReceived` notify), a not-joined verdict buffers the event verbatim (VEIL-029). kind-444 welcomes still ride the 1059 sub → routed to the same engine. `Intent::AcceptMarmotWelcome` joins the group, re-feeds the buffered 445s for its `h` tag in order, then reopens the sub; a welcome the engine can never accept (VEIL-117, a stale KeyPackage) drops the card instead of retrying forever. `Intent::SendMarmotMessage` encrypts + publishes then adds the plaintext locally (optimistic, `sent`). `Intent::StartMarmotChat` opens a 1:1 chat: an existing conversation with the peer is reused, never duplicated; otherwise a one-shot kind-30443 subscription fetches their newest KeyPackage (`KEY_PACKAGE_FETCH_TIMEOUT_MS`, `None` on timeout/absence — never errors), the engine's `create_group` builds the MLS group + welcome, and the welcome is published — a missing KeyPackage, an engine failure, or a publish rejection all surface as `ActionFailed` with no half-created group left behind. `Intent::SelectMarmotGroup` / `MarkMarmotRead` are pure store ops. `MarmotView` + `Core::marmot_view()`. |
+| MDK/MLS engine relocation | `apps/mobile/src-tauri/src/marmot.rs` + `sqlstore.rs` | `client_core::marmot_engine` (feat `marmot`, SQLCipher) + `client_runtime::marmot::MarmotEngineImpl` | ✅ F2b — the MDK 0.8 / MLS + `rusqlite bundled-sqlcipher-vendored-openssl` engine moved verbatim into `client_core` behind feat `marmot` (off → `client-core` stays pure nostr+serde). `apps/mobile/src-tauri` now depends on `client-core` with `features = ["marmot"]` (same transitive stack, shared) and keeps only the Tauri command wrapper. CI builds + tests both `marmot` on and off. |
+| `tools/contract-harness/` (Node devtool) | new | `tools/contract-harness` | ✅ F2b — a real `BridgeCore` + `FakeSdkFacade` fronted by a genuine `ws://127.0.0.1:<port>` relay (`relayServer.ts`, a thin wire adapter over `@codedeck/testkit`'s `InMemoryRelay`), driven by a documented stdin/stdout JSON control protocol (`get-relay-url` / `open-pairing-window` / `emit-sdk-message` / `get-bridge-transcript` / `restart-bridge` / `drain-logs` / `shutdown` — see its `README.md`). `restart-bridge` shuts the current `BridgeCore` down and starts a fresh one with the same identity/storage/state dir — a real process-restart scenario, not a reset. Process + socket, no FFI shim, matching the plan's rejection of one. Wired into the pnpm workspace (`tools/*`); its own `typecheck`/`test`/`build` run under the existing recursive scripts, `./codedeck check` green. |
+| Rust integration test against the harness — Scenario A, in full (Layer 2 Go/No-Go gate) | `phoneCore.contract.test.ts` Scenario A | `crates/client-runtime/tests/contract_harness.rs` | ✅ F2b — spawns `node tools/contract-harness/out/main.js` as a real subprocess, speaks its stdin/stdout control protocol, and drives a real `client_runtime::Core` against it over an actual `ws://` socket, end to end: connect → `open-pairing-window` → `Intent::BeginPairing` → `pairing_view().phase == "paired"` → `Intent::CreateSession` → the harness's `list-sdk-sessions` names the spawned session → `emit-sdk-message` (init) → the session is visible in `machines_view()` → `emit-sdk-message` (assistant text) → rows land in the injected `MemoryTranscriptStore` → `Intent::SendInput` → the outbox item reaches `OutboxItemState::Confirmed` via a real `input-ack` → `restart-bridge` (the harness hands the resumed session a FRESH `FakeSdkFacade`, same as a real bridge restart killing the old SDK subprocess) → `BridgeCore`'s own resume-on-boot re-spawns the SAME session id → the bridge produces output while the phone is dark → `core.set_online(false)`/`set_online(true)` (the phone's own connectivity, independent of the bridge) → the FSM reconnects on its own, no manual nudging → sync gap-refill catches the phone's transcript up → asserted byte-identical to the bridge's own store, seq for seq. No FFI shim — process + socket, exactly as the plan calls for. `#[ignore]`d by default (needs Node + the harness build; `cargo test -p client-runtime --test contract_harness -- --ignored`), so `cargo test --workspace` needs no JS toolchain. Verified passing consistently across repeated runs (~0.5s each). |
+`Intent` / `CoreEvent` get a stable JSON shape | — (new) | `client_runtime::intent::Intent`, `client_runtime::core::CoreEvent` | ✅ F2b — both gained `Serialize`/`Deserialize` (`Intent`) and `Serialize` (`CoreEvent`, `SliceId`, `ActionFailed`): externally tagged, camelCase throughout (`{"sendInput":{"machine":...,"sessionId":...}}`, bare `"undoDelete"` for a unit variant) — needs BOTH `rename_all` (variant names) and `rename_all_fields` (struct-variant field names), a one-line-easy-to-miss serde gotcha caught by a dedicated round-trip test on each. Every field type either already touched the wire codec (`PermissionModifier`, `EffortLevel`, `PhoneToBridge`, …) or is a plain type serde handles natively, so this was additive — no `Intent::apply` or `Core` loop behavior changed. Per plan §2.5 the shape is stabilized, not frozen, until F3. |
+| Real persistent `Kv`/`TranscriptStore` for the native `Core` | `apps/mobile/src/platform/sqlite.ts` | `apps/mobile/src-tauri/src/native_ports.rs` | ✅ F2b — `KvSqlite` + `TranscriptStoreSqlite`, one shared `rusqlite::Connection`, opened INSIDE the core's own dedicated thread (`Connection` isn't `Send`; every `client_runtime` port lives behind an `Rc`). Deliberately schema-compatible with the WebView's existing migrations — same `codedeck.db` file, same `kv(key, value)` / `transcript(machine_pubkey, session_id, seq, kind, json, created_at)` tables — so an install upgrading onto the native path keeps its pairing, sessions, and transcript history. `corebridge.rs`'s `core_init` resolves `app_config_dir()` on the main thread (needs the `AppHandle`) then passes the bare path into the thread closure. Replaces F1's `CorePorts::default()` (fully in-memory — lost every store on every restart). |
+| `corebridge.rs` exposes the full View/Intent/CoreEvent surface | `createPhoneCore.ts` | `apps/mobile/src-tauri/src/corebridge.rs` | ✅ F2b — `core_dispatch(intent: Intent)` (one command for all ~30 actions, `Intent`'s own JSON shape, no hand-rolled decoding) + `core_machines_view` / `core_settings_view` / `core_outbox_view` / `core_pairing_view` / `core_dm_view` / `core_marmot_view` (each a thin wrapper over the matching `Core::*_view()`; `core_connection_status` from F1 already covers `ConnectionView`'s ground) + `TauriObserver::on_event` forwarding the full semantic `CoreEvent` stream as a new `core://event` Tauri event (additive to F1's three hand-mapped events). All `native-core`-gated; the default build is untouched. |
+| Real `Notifier` for the native `Core` | `apps/mobile/src/platform/notifier.ts` | `apps/mobile/src-tauri/src/corebridge.rs`'s `TauriNotifier` | ✅ F2b — `corebridge.rs`'s `CorePorts` used `..CorePorts::default()` for `notifier`, i.e. `NullNotifier`: a native-core boot would have silently delivered ZERO OS notifications (DMs, turn-finished, permission prompts) — found while wiring the `main.tsx` cutover, not part of the original 3 documented gaps. `TauriNotifier` calls `tauri-plugin-notification`'s Rust API (`AppHandle::notification().builder().title(..).body(..).show()`) directly from the core's own thread — the same plugin the WebView path drives over its JS bindings, no new IPC surface needed. `cancel` stays the trait's own default no-op: the plugin's remove-by-id call is exposed to the JS side (`removeActive`) only, and duplicating the WebView notifier's per-tag id bookkeeping just to auto-dismiss a resolved permission-request notification isn't worth it yet — a resolved card's notification lingers until swiped away, but nothing is ever silently dropped. |
+| `MachineView.provider_profiles` — fix `#[serde(skip)]` | — (bugfix) | `client_core::stores::machines` | ✅ F2b — the field was skipped in EVERY serialization, not just `serialize_machines`'s KV-persistence path, so it would have silently never reached the live `MachinesView` an IPC consumer reads. Now carries `skip_serializing_if` instead, and `serialize_machines` strips it explicitly before persisting — the one place CDX-062 actually needs it gone. |
+| `MarmotView` — add `available` + `pendingWelcomes` | — (bugfix) | `client_runtime::view::MarmotView` | ✅ F2b — `client_core::stores::marmot::MarmotState` already tracked both (the engine-ready flag and the pending-welcome map an accept-welcome UI needs), but `MarmotView::from_stores` dropped both on the floor: a native-core phone would have permanently hidden "start a Marmot chat" and made every incoming welcome invisible, with the underlying transport already working end to end. Added `MarmotWelcomeInfo`'s missing `Serialize`/`Deserialize`. |
+| `QuickPromptsView` (new) | `apps/mobile/src/core/stores/quickPrompts.ts` (read side) | `client_runtime::view::QuickPromptsView` | ✅ F2b — `client_core::stores::quick_prompts::QuickPromptsState` already backed the CRUD `Intent`s end to end, but had no view at all. Thin over `quick_prompts.prompts`, `Core::quick_prompts_view()`, `core_quick_prompts_view` Tauri command. Also split `SliceId::QuickPrompts` out of the `StoreId::QuickPrompts → SliceId::Settings` mapping it shared before this view existed — quick prompts changing no longer needs a settings re-fetch to notice. |
+| `PendingSessionsView` (new) + `Intent::DismissPendingSession` | `apps/mobile/src/core/stores/pendingSessions.ts` (read + dismiss) | `client_runtime::view::PendingSessionsView` | ✅ F2b — `client_core::stores::pending_sessions::PendingSessionsState` already applied every `session-pending`/`session-ready`/`session-failed` message via the `Router`, but nothing surfaced that state: no view, and no mutation ever fired a `CoreEvent` (this store is deliberately never persisted, so a `stateChanged` is the ONLY way a consumer learns to re-fetch). Added `pending_sessions_changed` to both `RouteResult` and `IntentResult` (the same non-persisted-but-notify-worthy pattern the `Cards` slice already uses for `r.notifies`), a dedicated `SliceId::PendingSessions`, and `Intent::DismissPendingSession` for the one user-facing mutation (a failed card's dismiss button) that had no way to reach the store at all. |
+| `UiView` (new) + `Intent::SetPlanApprovalChoice` | `apps/mobile/src/core/stores/ui.ts` (read + the 4 user-facing mutators) | `client_runtime::view::UiView` | ✅ F2b — `UiState` (F2a) already ported the full selection + optimistic interaction-card bookkeeping, but had no view and most of its mutation points never fired a `CoreEvent`. `UiView` is `UiState` verbatim — NOT the plan §2.1 `CardsView` (a different, larger, per-session projection of actual card *content* that lands with the transcript-view work); this is only the flat bookkeeping around cards. Added `ui_changed` to both `RouteResult` and `IntentResult`, wired at every low-frequency mutation site (`SelectSession`/`SelectDmPeer`/`SelectMarmotGroup`, `RespondPermission`'s card-responded mark, `SendInput`'s unread-clear, the delete-controller's undo-toast/deselect effects, the three bridge-ack handlers) but deliberately NOT the high-frequency per-output-chunk unread-clear path (would spam refetches for a low-stakes dot on nearly every streamed token). `Intent::SetPlanApprovalChoice` closes the one piece of `UiState` with no existing Intent at all. |
+| `TranscriptRowsView` (new) + `CoreEvent::TranscriptAppended` | `apps/mobile/src/core/stores/transcript.ts` (read side) | `client_runtime::view::TranscriptRowsView` | ✅ F2b — the one view backed by I/O (`TranscriptStore`, SQLite on device) rather than a synchronous snapshot: reads `1..=local_high` via the same `read_range` the write path already used and combines it with the in-memory sync/coverage state. `TranscriptAppended { machine, sessionId }` is a dedicated per-session event (not a generic `StateChanged{Transcript}`) fired on every `Output`/`SyncChunk` — deliberately NOT throttled like `ui_changed`, since a transcript view's whole purpose is to look live. |
+| `BridgeApiLike` (new) + `createNativeBridgeApi` | `apps/mobile/src/core/services/bridgeApi.ts` | `apps/mobile/src/core/services/nativeBridgeApi.ts` | ✅ F2b — `PhoneCore.api` was typed as the concrete `BridgeApi` class; widened to an interface (`BridgeApi` now declares `implements BridgeApiLike`, zero behavior change) so a second implementation could dispatch `Intent`s instead of building/signing/publishing commands itself. Covers every method that has an `Intent` (all of them, after `SetCredentials`/`SetProviderProfile`/`SetDeviceConfig`/`CreateFolder`); `diagnostics` stays a zeroed inert field (nothing here ever decrypts/decodes a wire message). `ingest`/`input`/`dispatchDecoded` — the F1 in-process-runtime branch these existed for — were later found to have zero production callers at all and were deleted outright, not kept as no-ops. `createFolder` now has a real correlated-response path: `Intent::CreateFolder` → bridge `folder-ack` → `CoreEvent::FolderAck` matched by `request_id`. `uploadImageBlossom`/`uploadImageChunk` stay deliberate, documented rejections — their two-stage shape is already ONE step inside `Intent::SendSessionImage`, so shimming them individually would double-upload. |
+| `Intent::RemoveMachine` (new) | `apps/mobile/src/core/createPhoneCore.ts`'s `removeMachine` | `client_runtime::intent::Intent::RemoveMachine` | ✅ F2b — purely local (no wire message: the bridge has no concept of "unpaired", it just stops hearing from a phone that stopped listening). Gathers the machine's session ids from `MachineView.sessions` (same source the TS version reads), drops the machine, clears each session's unread dot, deselects if it was selected, and queues each session for transcript-row removal — added `transcript_removed` to `IntentResult` (mirroring `RouteResult`'s tombstone-driven field) and cleared `TranscriptState`'s in-memory coverage via `remove_session` alongside the row-store delete, or a stale `local_high` would make `TranscriptRowsView` report rows that were already gone. `resubscribe` drops it from the authors filter. `createPhoneCoreNative.ts`'s `removeMachine` now dispatches this instead of being a no-op. |
+| Real `HttpFetch` for the native `Core` | `apps/mobile/src-tauri`'s `plugin-http`-backed WebView escape hatch (CDX-029) | `apps/mobile/src-tauri/src/native_http.rs`'s `ReqwestHttpFetch` | ✅ F2b — `corebridge.rs`'s `CorePorts` used `..CorePorts::default()` for `http`, i.e. `NoHttpFetch`: every Blossom upload/download would have failed under native-core (found wiring the `SessionScreen.tsx` image-send branch, not part of the original 3 documented gaps). Reuses `tauri-plugin-http`'s OWN `reqwest` (re-exported as `tauri_plugin_http::reqwest`) rather than adding a second HTTP stack — the WebView path already depends on this exact crate as its CORS escape hatch. SOCKS5-aware: `core_init`'s `InitConfig::proxy` (the same `host:port` the WS transport dials when Tor is on) configures an identical `reqwest::Proxy`, so a Blossom upload never bypasses Orbot while the relay sockets don't either — the `socks` feature is forwarded onto `tauri-plugin-http` only via the `native-core` Cargo feature (`tauri-plugin-http/socks`), never unconditionally, so the default build's dependency graph is untouched. `set_proxy` rebuilds the client (proxies bake in at build time — no in-place update) when `Intent::SetTorEnabled` fires, same live-toggle wiring as the WS transport below. |
+| `PhoneCore.sendSessionImageNative` + the `SessionScreen.tsx` native branch | `apps/mobile/src/ui/screens/SessionScreen.tsx`'s `sendWithImage` | `apps/mobile/src/core/createPhoneCoreNative.ts` | ✅ F2b — the one `PhoneCore` method the native composition defines that the local one does not (optional on the interface): `Intent::SendSessionImage` already does the whole Blossom-upload-then-chunk-fallback as one step in Rust, so there is no way to plug that into `BridgeApiLike`'s `uploadImageBlossom`/`uploadImageChunk` shape without either double-uploading or silently breaking the documented fallback (see `createNativeBridgeApi`'s doc). `SessionScreen.tsx` checks for the method's presence and, when native, decodes the staged file's base64 to raw bytes (`base64ToBytes`, already used elsewhere) and dispatches directly — no `BridgeApi` calls, no fine-grained upload progress (the spinner covers the one dispatch), no true cancellation of an in-flight send (the same outer `withDeadline` backstop applies, but a timeout only stops the spinner, not a send already handed to Rust). |
+| `main.tsx` capability check | `apps/mobile/src/main.tsx`'s `boot()` | same file, `bootNative` | ✅ F2b — landed as a `bootNative` / `bootLocal` split (a single `createNativeCore()` probe deciding the whole composition, not just the transport) while `native-core` was still opt-in. Once it became the default feature and `src/core`'s local composition was deleted, `bootLocal` and the probe's fallback branch went with it: `boot()` now calls `createNativeCore()` once and THROWS if it comes back null (no Tauri, or a Tauri build without the feature) instead of falling back to anything — there is no local path left to fall back to. The stay-connected foreground service and connectivity wiring are unchanged; the WebView-only `attachTorProxy` (`PROXY_OVERRIDE`) call site is gone from `main.tsx` entirely (native-core's transport dials its own SOCKS5 at `core.init`), leaving `platform/torProxy.ts` itself dead code — see the top status note. |
+| `CoreEvent`/`IntentResult::ui_effects` actually cancels notifications | `notificationsCoordinator.ts` (CDX-026c) | `client_runtime::core::Core::interpret_intent` | ✅ F2b bugfix — `Intent::SelectSession`/`SelectDmPeer` already returned the correct `UiEffect::SessionViewed`/`DmOpened` (proven by the `intent` module's own tests), but `interpret_intent` never read `r.ui_effects` at all: opening a session/DM the user was notified about left its OS notification sitting in the tray under native-core. Now maps each effect to `session_notify_tag`/`dm_notify_tag` (`client_core::notifications`, the same helpers `emit_notify` already used for delivery) and calls `self.notifier.cancel(tag)`. Found by re-auditing every `// … needs a … seam (F2b)` comment in `core.rs` after being asked "are there more gaps" — not part of the original 3, or of the `Notifier`/`HttpFetch` pair found earlier in this same pass. |
+| The undo toast never cleared on window expiry | `deleteController.ts` (via `notificationsCoordinator`) | `client_runtime::core::Core::on_undo_timer` | ✅ F2b bugfix — reported from a real device running the native-core benchmark APK: closing a session and never tapping undo left the banner up forever. `on_undo_timer` correctly cleared `stores.ui.undo_toast` (`delete_controller::commit`'s `HideUndoToast` effect) but emitted `StateChanged(Cards)` at the end instead of `StateChanged(Ui)` — `commit()` never produces a card effect at all, so nothing told a `UiView` consumer to re-fetch and notice the toast was gone. Tapping undo itself was unaffected (that path already goes through `apply_delete_effects`, which sets `ui_changed` correctly). Regression test pairs a machine, lists a session, deletes it, lets the real ~4s window elapse without ever dispatching `UndoDelete`, and asserts both the toast is gone and a `StateChanged(Ui)` fired for it — confirmed failing on the pre-fix code. |
+| Real `Notifier::cancel` for the native `Core` | `platform/notifier.ts`'s per-tag id bookkeeping | `apps/mobile/src-tauri/src/corebridge.rs`'s `TauriNotifier` | ✅ F2b — `TauriNotifier::cancel` was the trait's default no-op (a deliberate scope cut when `TauriNotifier` was first added). Now mirrors the JS notifier exactly: assigns an id per delivery (`.id(id)` on the builder, needed because `tauri-plugin-notification`'s mobile-only `remove_active` call removes by id, not tag), remembers ids per cancellation tag (capped, same as the JS side), and removes them on `cancel`. Desktop has no `remove_active` equivalent at all (`#[cfg(mobile)]`-gated; a no-op on desktop, matching the JS notifier's own graceful fallback). |
+| Real `Marmot` for the native `Core` | `platform/marmot.ts` + `stores/marmot.ts` | `apps/mobile/src-tauri/src/corebridge.rs` + `Cargo.toml` | ✅ F2b — `CorePorts.marmot` was the last field still defaulting to a stub (`NoMarmot`): the runtime-side wiring (`Core`'s full start sequence, `Intent::AcceptMarmotWelcome`/`SendMarmotMessage`/`StartMarmotChat`, see the two rows above) was already complete and tested, but `corebridge.rs` never constructed a real engine, so every Marmot chat would have failed outright under native-core. Fix was two lines of substance: forward `client-runtime`'s own `marmot` feature (already just `["client-core/marmot"]`) through the `native-core` feature list — `client-core`'s `marmot` feature was ALREADY unconditionally on for this crate (the WebView path's own `marmot.rs` Tauri commands need it), so this adds zero new compiled dependencies — then construct `MarmotEngineImpl::new(marmot_db_path)`. `marmot_db_path` resolves to the SAME `app_data_dir()/marmot.db` the WebView path's `marmot_init` command already opens, deliberately — an install switching between the two compositions must keep its MLS group state; losing it is unrecoverable (every chat needs a fresh invite). Found the same way as the notification-cancel fix above: this pass's own `..CorePorts::default()` comment ("`marmot` stays in-memory-default") was the tell. |
+| Re-point `apps/mobile` at the Rust `Core` + delete `src/core` | `createPhoneCore.ts` consumers | `apps/mobile/src/core/createPhoneCoreNative.ts` | ✅ F2b (composition, cutover, AND deletion landed) — `createPhoneCoreNative` assembles all eleven native store adapters (`createNative{Outbox,Settings,Pairing,Machines,Dm,Marmot,QuickPrompts,PendingSessions,Ui,Connection,Transcript}Store`) + `createNativeBridgeApi` into the `PhoneCore` shape `phoneCore.ts` now declares directly (relocated out of the deleted `createPhoneCore.ts`), so `usePhoneCore()` and every screen need zero changes to run against it. `identity.ts` needs no adapter (the TS side always owns loading/generating the persisted secret locally — it is the `core_init` *argument*, not something Rust exposes back). `PhoneCore.client` is gone entirely (nothing in production UI read it) and `sendSessionImageNative` is required, not optional, now that it is the only composition; `PhoneCore.api` is typed as `BridgeApiLike`. All 3 originally-documented gaps are closed (rows above), as are the 3 more this pass found (`Notifier`/cancellation, `HttpFetch`, `Marmot`). Verified with a real native-core benchmark APK build, not just `cargo`/`vitest`. `apps/mobile/src/core`'s local composition (`createPhoneCore.ts`, every store's local FSM/persistence half, `services/nostrClient.ts`, `platform/relayTransport.ts`, `deleteController.ts`, `notifications.ts`, `selectionPersistence.ts`, `defaultSessionMode.ts`, ~24 tests exercising them) is deleted; each surviving store file keeps only its shared types + pure helper functions native adapters or UI still call directly (`parsePairingUrl`, `sessionKeyOf`, `unifiedConversations`, `hydrateSettings`, …). `main.tsx` now has one boot path — no `bootLocal`, plain-browser dev no longer starts the app — and the `native-core` Cargo feature is `default = ["native-core"]`. The ~20 UI test files that used to fixture themselves against the local composition were migrated to a shared `fakeNativeCore()`/`buildFakePhoneCore()` helper (`core/__tests__/nativeCoreFixture.ts`) that scripts `NativeCore.dispatch` to behave like a real `client_runtime::Core` would, rather than re-implementing any Rust behavior in the fixture itself. |
+
+**F2a status: complete** — the whole pure `client-core` layer.
+
+**F2b status: the composed `Core` runs the full bridge protocol + NIP-17 DMs +
+Marmot group messaging in Rust.** `client_runtime::Core` hydrates the store
+bundle from the `Kv` port, folds every decoded `BridgeToPhone` through the
+`Router`, exposes the `View` / `Intent` / `CoreEvent` surface (plan §2), and
+drives the 1059 DM subscription, the Marmot start sequence (engine init →
+group reconcile → KeyPackage/10051 publish), the kind-445 group subscription
+(receive, send, accept-welcome + VEIL-029 re-feed), and the Blossom-first /
+chunk-fallback session image upload, and the `StartMarmotChat` KeyPackage
+fetch + group creation — proven end-to-end against the mock relay. The
+MDK/MLS engine is relocated into `client_core::marmot_engine` behind feat
+`marmot`; `client_runtime::marmot` carries the `MarmotEngine` port and its
+`MarmotEngineImpl`. ~423 workspace tests (marmot off) + 317 `client-core` lib
+tests with `--features marmot`, `clippy -D warnings` clean both ways.
+`tools/contract-harness/` (Node) exists and Scenario A — the F2b Layer 2
+Go/No-Go gate — passes in full from the Rust side:
+`crates/client-runtime/tests/contract_harness.rs` spawns it as a real
+subprocess and drives a real `client_runtime::Core` through pairing, session
+creation, live output landing in the transcript, an input reaching
+`Confirmed` via a real `input-ack`, a bridge restart with resume-on-boot, the
+phone's own FSM reconnecting on its own, and a sync gap-refill leaving the
+phone's transcript byte-identical to the bridge's — all over a genuine
+socket, no FFI shim. `Intent` and `CoreEvent` now carry a stable, tested JSON
+shape, and `apps/mobile/src-tauri`'s `native-core` feature exposes the full
+surface as Tauri commands (`core_dispatch` + six `core_*_view` queries + the
+`core://event` stream) over REAL persistence (`native_ports.rs`'s SQLite-backed
+`Kv`/`TranscriptStore`, schema-compatible with the WebView's existing
+`codedeck.db` so an upgrading install keeps its data), real OS notifications
+(`TauriNotifier`), and real Blossom HTTP (`ReqwestHttpFetch`, SOCKS5-aware) —
+replacing F1's in-memory-only ports. `apps/mobile/src` now runs on that
+surface exclusively (`main.tsx`'s single boot path, `createPhoneCoreNative.ts`)
+— see the port-tracking table's last rows. `apps/mobile/src/core`'s local
+composition is deleted and `native-core` is the default Cargo feature: this
+is the F2b stop-point the plan describes, reached and verified (`./codedeck
+check` + `cargo test`/`cargo clippy` both green, a real device smoke pass
+done by the maintainer). Whether the project continues into F3 (the first
+Compose screen) is a separate decision, tracked in the plan document, not
+this one.
+
+**Aside — a regression caught along the way:** the MDK-engine relocation
+earlier in F2b had removed `rusqlite` from `apps/mobile/src-tauri`'s direct
+dependencies (its own need for it, unrelated to MDK's, moved with it by
+mistake), which broke that crate's build entirely, in every feature
+configuration, undetected because verifying it needs the Tauri Linux system
+deps that a plain Rust container doesn't have and no PR had run it through
+CI yet. Fixed; see the git history for `apps/mobile/src-tauri/Cargo.toml` if
+this surfaces again after a future dependency shuffle — the lesson is that
+`cargo check` on the `crates/` workspace alone does NOT cover `apps/mobile/
+src-tauri`, which needs its own verification pass.
+
+Verify (`crates/`): `cargo test --workspace` + `cargo clippy --workspace
+--all-targets -- -D warnings` (CI `cargo` job, `core` filter). No host
+toolchain needed — run in `rust:1-bookworm` via Docker like the rest of the
+repo.
+
+Verify (`apps/mobile/src-tauri`, default (native-core) and
+`--no-default-features` both): `cargo test` / `cargo build
+--no-default-features` (CI `cargo` job, `rust` filter). This needs the Tauri
+Linux system deps (`libwebkit2gtk-4.1-dev libgtk-3-dev
+libayatana-appindicator3-dev librsvg2-dev patchelf`) installed into the same
+`rust:1-bookworm` image — a plain `crates/`-only container does NOT cover
+this crate at all (see the regression note above).

+### Transport parity checklist (plan §8)
+
+| # | Requirement | Rust | Covered by |
+|---|---|---|---|
+| 1 | 3 filters by traffic class: 30515 no-`since`; 4516 `since = cursor − 60s` (omitted on first run); 24515 no-`since`; `authors` = paired + candidate, `#p` = phone | `nostr_client::build_phone_filters` | `builds_exactly_three_filters`, `heartbeat_and_live_never_carry_since`, `response_filter_resumes_from_cursor_minus_grace_and_omits_on_first_run` |
+| 2 | Epoch guard (CDB-037): (re)connect bumps `epoch`; superseded callbacks ignored; teardown bumps `epoch` **before** closing; a deliberate teardown never emits `socket-close` | `nostr_client::{teardown_inner, connect}` + per-sub epoch check | `epoch_guard_deliberate_teardown_never_surfaces_as_close`, `events_from_a_superseded_epoch_are_dropped`, `real_subscription_death_reports_exactly_one_close_and_tears_the_epoch_down` |
+| 3 | EOSE = socket-open only when **every** current-epoch sub has EOSEd | `nostr_client` `on_eose` (`eose_count == filter_count`) | `connect_opens_three_subs_and_reports_open_after_all_eose`, `with_no_machines_connect_reports_a_vacuous_open` |
+| 4 | Dedup: `seenIds` cap 2000 FIFO; relays replay stored on reconnect | `nostr_client::SeenIds` | `dedups_replayed_event_ids_across_resubscribes` |
+| 5 | Cursor: `lastStoredSeen` = max `created_at` over 4516 + 30515; persisted | `nostr_client::handle_event` → `host.note_stored_seen`, which now also fires `Msg::NoteStoredSeen` to `Persister::save_last_stored_seen` | `tracks_stored_cursor_and_ignores_ephemeral`, `reconnect_resumes_response_filter_from_the_persisted_cursor`, `a_stored_kind_event_persists_the_cursor_to_kv`. The hydrate-side read (`LAST_STORED_SEEN_KEY`) and the `Persister` write already existed; only the live `note_stored_seen` → `Kv` wire was missing — a restart replayed the peer's entire stored history every time until this closed it |
+| 6 | Backoff `2s→30s` +25% jitter; Tor variant `8s→60s`; `online` after offline/waiting-retry = reconnect now, `attempt=0`; visibility debounce 500 ms never tears a healthy socket; `resume` with a live socket → refresh only | `connection::{connection_reducer, backoff_delay_ms, DEFAULT_RECONNECT_CONFIG, TOR_RECONNECT_CONFIG}`; `Core` picks the config from `tor` | `reconnect_storm_backs_off_monotonically_and_converges_at_the_cap`, `jitter_adds_at_most_25pct_never_negative`, `offline_closes_and_cancels_online_reconnects_fresh`, `visibility_flip_storm_produces_no_socket_churn`, `resume_while_connected_is_cheap_refresh_no_churn` |
+| 7 | CDX-020 dead-sub: `connected` + every machine heartbeat + `last_connected_at` older than 150 s → force `socket-close` | `connection::heartbeats_all_stale`; `Core` `StaleWatchdog` (30 s tick) | `all_stale_while_connected_past_grace_is_true`, `one_fresh_heartbeat_keeps_it_false`, `fresh_reconnect_gets_a_full_stale_window_of_grace`, `never_true_in_any_non_connected_status` |
+| 8 | `idleTimeout` neutralised / `enablePing` / `enableReconnect:false` | `WsTransport` has **no** idle timer (hand-rolled — the nostr-tools bug does not exist); `PING_EVERY 30s` + `DEAD_AFTER 75s` liveness; `ensure_connected` only redials, the FSM owns reconnect | `ws` loopback tests |
+| 9 | `publishConfirmed` 4-way: `accepted` / `unconfirmed` (frame written, no OK in the timeout — **not** failure) / `rejected` (`rate-limited:`/`blocked:`/`pow:`) / `unreachable` (`connection failure:` string); retry the **same** signed event within a budget | `bridge_api::{classify_publish, combine_publish}`; `transport::router` (settle on first `accepted`); `WsTransport::publish_confirmed` | `classify_publish_decodes_each_relay_outcome`, `combine_publish_takes_the_softest_verdict`, `publish_settles_immediately_on_first_acceptance`, `publish_timeout_settles_unconfirmed_for_the_silent_relays`, `publish_confirmed_maps_the_relay_ok_verdict`. Note: F1 retries only on `unreachable` (a `rejected` from every relay rejects the identical event identically) — deliberate |
+| 10 | NIP-42 AUTH answered with the identity key; one allowlisted pubkey per side | `nip42::build_auth_event`; `WsTransport` `answer_auth` on `AUTH`, `ResubAfterAuth` on `CLOSED: auth-required` | `nip42::*` (3), `router::auth_challenge_is_surfaced`, `router::auth_required_closed_asks_for_a_resub_not_a_close`, `ws::answers_nip42_auth_with_an_identity_signed_event` |
+| 11 | SOCKS5 per connection (`tokio-socks`); cleartext `ws://` only for `.onion` (or loopback, for the mock-relay test rig) | `WsTransport::dial` — `proxy` set → `Socks5Stream::connect` (DNS at the proxy, so `.onion` resolves); `wss://` → rustls; a cleartext `ws://` to any other host is now refused before dialing at all | `dial_refuses_cleartext_to_a_public_host`, `dial_does_not_refuse_cleartext_to_onion_on_scheme_grounds`, `dial_does_not_refuse_cleartext_to_loopback`. No TS-side equivalent check exists (checked: neither the phone nor the bridge ever validated a relay URL's scheme) — this transport-level refusal is now the only enforcement, and the only one needed |
+| 12 | Toggling Tor live redials every relay through the new proxy setting, no app restart needed | `WsTransport::set_proxy` (redials every open connection); `NostrClient::set_proxy`; `Loop::tor_proxy_address` remembers the SOCKS5 address independent of on/off state, since `Intent::SetTorEnabled` only carries a bool; `ReqwestHttpFetch::set_proxy` does the same for Blossom uploads (rebuilds the client — `reqwest` bakes its proxy in at construction) | `set_proxy_updates_what_the_next_dial_uses_and_closes_every_live_connection`, `set_proxy_swaps_the_client_live_in_both_directions`. Previously both were "known gaps" (`r.tor_changed` was computed and then dropped on the floor) — closed by having the phone always send the real SOCKS5 address in `InitConfig.proxy` (not nulled out when starting with Tor off) so `Loop` has something to switch back to |

+# `fixtures/corpus.json` — the shared codec conformance corpus
+
+The executable half of "one source of truth" for the wire. `packages/protocol`
+(zod) is the **normative spec**; `crates/protocol` is a Rust mirror of
+it. This corpus is what keeps them from drifting.
+
+## Consumed by
+
+| Side | Test | Runner |
+|---|---|---|
+| TS | `packages/protocol/src/__tests__/fixtures.test.ts` | `pnpm test` (CI `verify` job) |
+| Rust | `crates/protocol/tests/codec_conformance.rs` | `cargo test` (CI `cargo` job — `core` path filter includes `fixtures/**`) |
+
+Both run the **identical assertions on the identical bytes**:
+
+- `phoneToBridge.valid` / `bridgeToPhone.valid` — each decodes, and
+  `encode(decode(x))` re-decodes to an equal value (semantic round-trip).
+- `phoneToBridge.rejected` / `bridgeToPhone.rejected` — each is a decode error.
+- `forwardCompatible` — each still decodes (unknown fields are ignored, matching
+  zod's default strip and serde's default behaviour).
+
+A schema change mirrored on only one side fails CI there.
+
+## How it stays complete and correct
+
+- **Correct:** every `valid` entry is run through the real `decode*` (= zod
+  `safeParse` / serde), so a fixture that isn't actually valid per the spec
+  fails the test. Same for `rejected`.
+- **Complete:** `fixtures.test.ts` introspects `phoneToBridgeSchema` /
+  `bridgeToPhoneSchema` for the full set of `type` literals and asserts the
+  corpus covers every one (and names no unknown type). Add a message type to
+  the union → this test fails until the corpus has a fixture for it.
+
+It is **hand-curated on purpose** — a random generator (`zod-mock` &c.) produces
+non-deterministic, non-representative data and can't express the deliberate
+edge cases (tristate keep/clear/set, empty `models` + `error`, the two
+`upload-image` shapes, a heartbeat with tombstones + `machineOffline`).
+
+## Adding a message / field
+
+1. Change the zod schema in `packages/protocol/src/schemas/`.
+2. Mirror it in `crates/protocol/src/`.
+3. Add / update the fixture(s) here.
+4. `pnpm --filter @codedeck/protocol test` and
+   `cargo test -p client-core` must both pass.

+# F0 · probe 3 — background reliability
+
+> **THROWAWAY.** Delete once the verdict is folded into the plan (or an ADR).
+
+## Status: **GO on the emulator** · real-OEM pass still required before F1 commits
+
+The plan's central thesis is "sockets in a Rust core inside the foreground
+service keep delivering while the app is backgrounded / Dozed, where WebView
+sockets do not". Both halves now pass:
+
+| Half | State |
+|---|---|
+| **Networking core** (Rust relay client: subscribe kind-30515, count deliveries, reconnect with backoff) | ✅ **GO** — host tests green |
+| **On-device** (that core, hosted by a real Android `dataSync` foreground service, on a wiped API-36 emulator) | ✅ **GO** — full matrix DELIVERING (`artifacts/emulator-matrix.log`) |
+
+### Emulator matrix result (pulse every 15 s)
+
+| phase | heartbeats received | reconnects | verdict |
+|---|---|---|---|
+| foreground baseline | 2 → 4 | 0 | DELIVERING |
+| backgrounded (HOME) | 4 → 7 | 0 | DELIVERING |
+| screen off | 7 → 10 | 0 | DELIVERING |
+| **forced Doze** (`dumpsys deviceidle force-idle`) | 10 → 15 | 0 | DELIVERING — socket survived Doze, zero reconnects |
+| after airplane-mode blip | 15 → 17 | 4 → 5 | DELIVERING — dropped, backoff-reconnected, resumed |
+
+The FGS `dataSync` exemption + the persistent socket held through Doze with no
+teardown; airplane toggles exercised the reconnect FSM and it recovered.
+
+## What is proven (networking core)
+
+`rust/heartbeat-core` — a real `tokio-tungstenite` client:
+
+- `counts_heartbeat_deliveries` — connects, sends `REQ` for
+  `{kinds:[30515], authors:[…], #p:[…]}`, counts each `EVENT`, exposes
+  `ProbeStats { connected, received, last_heartbeat_ms, reconnects }`.
+- `reconnects_after_socket_drop_and_resumes` — relay drops the socket after N
+  events; the core emits `Disconnected` → `Reconnecting { attempt, delay_ms }`
+  (exp backoff 1→32 s, cap 30 s) → `Connected` again and resumes counting.
+- Consumed on Android via **UniFFI** (the pattern probe-1 validated) — the
+  generated `HeartbeatProbe` / `ProbeListener` / `ProbeEvent` / `ProbeStats` are
+  wired into `RelayService` and compile + package into the APK.
+
+## What is built and ready (on-device)
+
+- **`android/`** — a minimal native app. `RelayService` (`foregroundServiceType="dataSync"`,
+  `START_STICKY`, optional `PARTIAL_WAKE_LOCK`) **owns the Rust core**; the socket
+  lives in the service process, not a WebView. `MainActivity` shows the running
+  count; `adb`-drivable via `am start -n …/.MainActivity --ez auto true [--ez wl true]`.
+- **`pulse-relay`** — a WS stand-in for "a bridge emitting kind-30515", every 15 s.
+- **`build.sh`** — one Docker image (Rust + NDK r28c + cargo-ndk + JDK 17 +
+  Android cmdline-tools) → `cargo test` → `libheartbeat_core.so` (x86_64 + arm64)
+  → `uniffi-bindgen` → **`artifacts/bgprobe-debug.apk`** (builds green).
+- **`run-emulator.sh`** — installs the APK, starts `pulse-relay` on host `:7447`,
+  runs the matrix: `foreground baseline → app backgrounded (HOME) → screen off →
+  forced Doze (dumpsys deviceidle force-idle) → airplane blip`, printing
+  `DELIVERING` / `!! STALLED` per phase from logcat.
+
+## Still required before F1 fully commits
+
+A pass on a **real Samsung/OneUI + a real Xiaomi/MIUI** device (see the emulator
+caveat below). Run `./spike/background-probe/run-emulator.sh` after
+`adb connect`-ing the device, or drive the matrix by hand:
+`am start -n …/.MainActivity --ez auto true`, then HOME / power / leave 30+ min /
+toggle wifi+data, watching `adb logcat -s bgprobe`.
+
+## Findings so far
+
+- `#[uniffi::export]` without `async_runtime` is correct when no public method is
+  `async` (probe-1 used the async attr deliberately; this core does not — it owns
+  its tokio runtime internally, created in `start()`).
+- APK build tooling: **compileSdk 36** here — the API-37 platform ships SDK XML
+  v4, which the sdklib bundled in the Dockerized AGP 8.11.1 cannot parse
+  (`Failed to find target android-37`). A native Android Studio build (matching
+  newer sdklib) handles 37; the real `apps/android` still targets 37. This is a
+  tooling-version bump for F3, not an architecture risk.
+
+## Hard limitation of the emulator for this probe
+
+A stock AOSP / Google-APIs emulator is **lenient** — it honours forced Doze and
+app-standby, but it does **not** reproduce Samsung/OneUI or Xiaomi/MIUI
+proprietary background killing, which is the actual reason CodeDeck's background
+is unreliable today. **An emulator GREEN is necessary but NOT sufficient.** A
+real Samsung + a real Xiaomi pass remain a hard gate before F1 fully commits.
+
+## Reproduce / continue
+
+- core only: `docker run --rm -v .../background-probe:/s -w /s/rust/heartbeat-core rust:1-bookworm cargo test`
+- APK: `./spike/background-probe/build.sh`
+- emulator matrix: `./spike/background-probe/run-emulator.sh` (wipe/roomy AVD;
+  `AVD=<name>` to override). The API-36 AVD used here was factory-reset first
+  (`emulator -avd <name> -wipe-data`).
+
+## Delete criteria
+
+Once probe-3's verdict (both halves) is recorded in the plan, `rm -rf spike/background-probe/`.

+# F0 · probe 4 — Markdown / transcript parity in Compose
+
+> **THROWAWAY.** Delete once the verdict is folded into the plan (or an ADR).
+
+## Verdict: **GO — with a scoped renderer decision required in F3**
+
+Compose transcript rendering can reach parity, but a Markdown renderer is **not
+a library drop-in** for CodeDeck's corpus: tables, task-list checkboxes and
+syntax highlighting all need explicit work, and there is a real
+Kotlin/AGP/Paparazzi/Compose/renderer version matrix to lock.
+
+| Question | Answer |
+|---|---|
+| Screenshot-test Compose rendering off-device (the F3 fidelity guardrail)? | ✅ **Yes** — Paparazzi runs in Docker on the JVM (no emulator); `:ui:recordPaparazziDebug` → golden PNGs. |
+| Do the **bespoke** rows (diff card, tool group, cards) port with matching fidelity? | ✅ **Yes** — `diff_card` / `tool_group` goldens match the near-black monochrome (`+` green / `-` red / dim mono). Near-verbatim ports of `DiffRow.tsx` etc. |
+| Does a Compose Markdown renderer cover the corpus out of the box? | ⚠️ **Partly** — see the table below. |
+
+## What the Markdown renderer (mikepenz 0.27, synchronous) does / doesn't
+
+`artifacts/probe_ParityTest_assistant_markdown_gfm_and_code.png`:
+
+| feature | result |
+|---|---|
+| headings, paragraphs | ✅ render, white on black |
+| ordered / unordered / **nested** lists | ✅ |
+| inline code | ✅ monospace on `#0D0D0D` |
+| **5 fenced code blocks** (bash / ts / rust / json / diff) | ✅ render as monospace blocks |
+| **GFM table** | ❌ renders as **stacked plain lines**, not a grid — even with `GFMFlavourDescriptor()`. Needs a custom `markdownComponents(table = …)` or a newer renderer version. |
+| **task-list checkboxes** (`- [x]` / `- [ ]`) | ❌ render as plain `•` bullets |
+| **syntax highlighting** | ❌ absent (monochrome). Needs the `-code` module (version-locked) or Rust/`syntect` spans emitted from `client-core`. |
+| blockquote | ⚠️ not visibly distinct from a paragraph |
+| link | renders inline, styling minimal |
+
+## The version treadmill (must be locked for F3)
+
+- `Markdown(content = …)` in mikepenz **≥ ~0.30 parses asynchronously** →
+  Paparazzi's static snapshot catches the empty frame (blank golden). Needs a
+  synchronous path.
+- The synchronous `Markdown(content)` exists in **0.27**, but 0.27 predates
+  built-in table rendering.
+- **0.39.x requires Kotlin 2.2** (`kotlin-stdlib 2.3`); this probe is on Kotlin
+  2.0.21 (Paparazzi 1.3.5 / AGP 8.7.3 constraint) → 0.39 fails to compile
+  (`incompatible metadata version 2.2.0`).
+- Intermediate versions drift the `-android` / `-m3` / `-code` modules apart
+  transitively → runtime `NoSuchMethodError` unless every module is pinned.
+- Colour: text colour comes from `markdownTypography(...)` per-slot `TextStyle`s
+  and `LocalContentColor` (via a `Surface`), **not** `markdownColor(text=…)`
+  (deprecated). The dark-only theme needs every slot set explicitly.
+
+## Recommendation for F3
+
+1. Adopt **Paparazzi** (proven here) as the transcript-fidelity guardrail.
+2. **First F3 task = a transcript-screen spike**: lock one
+   Kotlin/AGP/Paparazzi/Compose/renderer version set; get tables + task lists +
+   blockquotes rendering (custom components if needed); capture goldens for the
+   whole corpus; diff against a **reference capture from the running React app**
+   (`apps/mobile` on `pnpm dev`, fixed width).
+3. **Syntax highlighting is its own decision** — accept coarse `highlights`,
+   theme it toward the current hljs palette, or emit spans from Rust
+   (`syntect`/`tree-sitter`) in `client-core`. Budget explicit effort; it is the
+   single biggest fidelity gap.
+4. This widens the F3/F4 UI scope but does **not** threaten stopping at F2b — the
+   work is bounded and known.
+
+## Reproduce
+
+`./spike/markdown-compose-probe/run.sh` (Docker only; reuses the
+`codedeck-bgprobe-build` image for JDK + Android cmdline-tools).
+
+## Delete criteria
+
+Once this verdict is recorded in the plan (or an ADR), `rm -rf spike/markdown-compose-probe/`.

+# F0 · probe 2 — NDK / SQLCipher / Marmot in the new workspace layout
+
+> **THROWAWAY.** Delete once the verdict is folded into the plan (or an ADR).
+
+## Verdict: **GO**
+
+The MDK 0.8 / MLS + SQLCipher stack from `apps/mobile/src-tauri` survives the
+plan's re-layout — living in `crates/client-core` as a **workspace member** and a
+**cdylib**, **alongside the `uniffi` proc-macro stack** — and still
+cross-compiles to `aarch64-linux-android`. Feature unification for
+`rusqlite` / `openssl-src` holds across the workspace.
+
+## What was proven
+
+| Risk (plan §7 F0-probe-2) | Result |
+|---|---|
+| `rusqlite` `bundled-sqlcipher-vendored-openssl` unification breaks in a workspace | ✅ holds — `client-core` keeps the direct `rusqlite` dep, `mdk-sqlite-storage`'s `bundled-sqlcipher` unifies up to it, second workspace member (`client-runtime-min`) depends on `client-core` and resolution stays correct |
+| SQLCipher + vendored OpenSSL C don't cross-compile for Android | ✅ `libclient_core.so` = **ELF ARM aarch64**, 14.5 MB, SQLCipher + OpenSSL C linked in |
+| `secp256k1` C (via `nostr` 0.44) doesn't cross-compile for Android | ✅ linked into the same `.so` |
+| `uniffi` proc-macros can't coexist with `openmls` / `mdk-core` in one crate | ✅ `uniffi::setup_scaffolding!()` + `#[uniffi::export]` compile alongside the full MLS stack |
+| the MLS code path actually runs (not just links) | ✅ host test: two SQLCipher stores opened, key package minted + verified, 1:1 MLS group created, 2 members; a second test confirms the db file has **no plaintext `SQLite format 3` header** (encryption is real) |
+
+## Findings
+
+- **`cargo-ndk` + NDK r28c needs no `AR_/RANLIB_` env hacks.** The old
+  `apps/mobile/docker/Dockerfile` exports
+  `RANLIB_/AR_aarch64_linux_android` to NDK llvm tools to work around an
+  `openssl-src` GNU-name issue (CDX-012). With `cargo-ndk` driving the build and
+  NDK r28c, the arm64 cross-build of `bundled-sqlcipher-vendored-openssl`
+  succeeds with **zero** manual toolchain env. The real `apps/android` Gradle
+  build should use `cargo-ndk` and can likely drop those exports.
+- The lean image (Rust + one NDK + `cargo-ndk`, no Android SDK, no Gradle) is
+  enough for a `.so` cross-build — useful for a fast CI `cargo check --target
+  aarch64-linux-android` gate before the full APK job.
+
+## Not covered here
+
+- **Running** the `.so` on-device / emulator — that's F0-probe-3 + F3.
+- `armeabi-v7a` / `x86_64` ABIs — trivial add (`-t armeabi-v7a -t x86_64`), not
+  needed to answer the risk.
+- Stripping / final `.so` size budget — an F1/F3 concern (`≤ 50 MB` per plan).
+
+## Versions
+
+NDK r28c (28.2.13676358, matches `apps/mobile/src-tauri`) · rustc 1.98 ·
+mdk-core / mdk-sqlite-storage / mdk-storage-traits 0.8 · nostr 0.44.8 ·
+rusqlite 0.37 (`bundled-sqlcipher-vendored-openssl`) · uniffi 0.28.3 ·
+cargo-ndk (latest)
+
+## Reproduce
+
+`./spike/ndk-marmot-probe/run.sh` (Docker only; first run downloads NDK ~600 MB).
+
+## Delete criteria
+
+Once this GO is recorded in the plan (or an ADR), `rm -rf spike/ndk-marmot-probe/`.

+# F0 · probe 1 — UniFFI binding ergonomics
+
+> **THROWAWAY.** This whole `spike/` tree exists only to answer, with running
+> code, migration plan §7 **F0-probe-1**. Delete it once the verdict below is
+> folded into the plan (or an ADR).
+
+## Verdict: **GO**
+
+A UniFFI-generated API for the future Rust `client-core` is idiomatic from
+Kotlin/Compose and clean to consume from Tauri. Every hard case — foreign
+callbacks, `async` commands, typed errors, object lifecycle with a background
+task, and concurrency — works at runtime through the real FFI. Proceed with the
+planned split: `client-core` (pure Rust) → `client-runtime` (async) → **UniFFI**
+for `apps/android`, **`#[tauri::command]`** for `apps/desktop`.
+
+## What was exercised
+
+| Risk (plan §7 F0-probe-1) | How | Result |
+|---|---|---|
+| Foreign-implemented callback trait | Kotlin `class Collector : CoreListener`, Rust bg task calls `on_event` from its own thread | ✅ callbacks land on the Kotlin object |
+| `async fn` command → Kotlin `suspend fun` | `Core::dispatch` is `#[uniffi::export(async_runtime = "tokio")]`; called from `runBlocking` / `async{}` | ✅ real `suspend fun dispatch(intent: Intent)` |
+| Typed error across the boundary | `CoreError` / `CryptoError` enums → `sealed class CoreException : Exception()` | ✅ `assertFailsWith<CoreException.Rejected>`, `.reason` readable |
+| Object lifecycle + bg task, no leak | `start()` spins a `tokio::runtime::Runtime` + task; `stop()` aborts + `shutdown_background()` | ✅ no events after `stop()`; `Core : AutoCloseable` |
+| Concurrency | 50 concurrent `suspend` dispatches while the bg task emits to a Kotlin listener | ✅ exactly 50 `StateChanged`, ≥1 `TranscriptAppended`, no loss/dup/deadlock |
+| Real NIP-44 v2 over FFI (plan risk #13) | `nostr` crate `nip44`, `String` in/out | ✅ round-trips; footprint measured (below) |
+| Same API from Tauri | `tauri-consumer` crate: `#[tauri::command]` async + typed error + `emit` event stream | ✅ `cargo check` clean |
+
+## Evidence (all green)
+
+- **Native:** `client-core-probe/tests/native.rs` — 3 `cargo test`, `cargo clippy -D warnings` clean.
+- **Through the FFI:** `kotlin/src/test/kotlin/ProbeTest.kt` — 4 JUnit tests via JNA against the real `libclient_core_probe.so`.
+- **Tauri:** `tauri-consumer/` — `#[tauri::command] { dispatch (async), snapshot, start, stop }` + `wire_events` (`CoreListener` → `AppHandle::emit`) compile.
+- **Compose shape:** `kotlin/src/main/kotlin/ProbeViewModel.kt` — the intended `ViewModel` over the bindings compiles: sealed `CoreEvent` folds into a `StateFlow`, `dispatch` in a coroutine, `CoreException` subclasses caught normally. ~45 LOC of glue, **zero domain logic**.
+
+Reproduce: `./spike/uniffi-binding-probe/run.sh` (Docker only — no host toolchain).
+
+## Generated Kotlin — ergonomics assessment
+
+The `uniffi-bindgen` output (`kotlin/bindings/…/client_core_probe.kt`) is what a
+Compose app would import:
+
+```kotlin
+suspend fun dispatch(intent: Intent)                 // real coroutine suspend, @Throws(CoreException)
+sealed class CoreEvent { data class StateChanged(val slice: String) : CoreEvent(); … }   // exhaustive when
+sealed class Intent    { data class SendInput(val session: String, val text: String) : Intent(); … }
+sealed class CoreException : kotlin.Exception() { class Rejected(val reason: String) : CoreException(); … }
+data class ProbeView(var running: Boolean, var seq: ULong, var listenerCount: UInt)
+open class Core : Disposable, AutoCloseable { … }    // use {} / .destroy(), Cleaner fallback
+interface CoreListener { fun onEvent(event: CoreEvent) }
+```
+
+Rust `///` docs are carried through to KDoc. Nothing here needs a wrapper layer
+to be pleasant in Compose.
+
+## Findings to fold into the real `client-core` (both are trivial conventions)
+
+1. **A fielded UniFFI error variant must not name a field `message`.** It
+   collides with Kotlin's `Throwable.message` and the 0.28 codegen does not emit
+   `override` → the generated `.kt` won't compile. Convention: error fields are
+   `detail` / `reason` / domain-specific — never `message`. Cheap to enforce in
+   the planned anti-drift lint.
+2. **`#[tauri::command]` functions go in a submodule, never a library crate's
+   root** — the macro's `#[macro_export]` collides with its own local re-export
+   there. `apps/desktop` will have a `commands` module regardless, so this is a
+   non-issue in practice; noted so the real code starts that way.
+
+## Data — `nostr` crate footprint (plan risk #13: hand-roll vs `nostr`)
+
+`nostr 0.44` with `default-features = false, features = ["std", "nip44"]` pulls,
+at depth 1: `base64 bech32 bitcoin_hashes chacha20 hex secp256k1 serde
+serde_json url`. The only heavy item is **`secp256k1`** (vendored C) — and secp
+ECDH is unavoidable for NIP-44 whether hand-rolled (`k256`/`secp256k1`) or not.
+
+**Conclusion:** leaning on `nostr` for NIP-44 in F1 is fine and not bloated. A
+hand-roll would only shave `serde_json` + `url` off the leaf — revisit only if
+`.so` size becomes a real constraint.
+
+## Also confirmed
+
+- **`uniffi` + `serde` derives compose on the same type** → one definition of a
+  boundary type (`Intent`, `CoreEvent`, `ProbeView`, `CoreError`) serves both the
+  Kotlin (UniFFI) and the Tauri (serde/JSON) binding. No DTO duplication.
+- The async bridge (`async_runtime = "tokio"`) coexists with the `Core`'s own
+  owned `Runtime` for the bg task — two runtimes, no clash.
+- `Runtime::shutdown_background()` (not `drop`) is the safe teardown from a sync
+  FFI method.
+
+## Not covered here — follow-ups
+
+- **F0-probe-2** (NDK / SQLCipher / Marmot cross-compile in the new workspace) — needs `aarch64-linux-android` + NDK 28.
+- **F0-probe-3** (background reliability on real Samsung/Xiaomi/Pixel) — needs hardware; the maintainer runs it.
+- **F0-probe-4** (Markdown/Compose transcript parity) — independent.
+- **arm64 Android build** of these bindings (`.so` per ABI) — F3 scaffolding.
+- **Coroutine cancellation** of an in-flight `suspend dispatch` → Rust future drop — worth an explicit check in F1.

+# `@codedeck/contract-harness`
+
+A standalone process that runs one real `BridgeCore` (from `@codedeck/core`)
+behind a scriptable `FakeSdkFacade` (from `@codedeck/testkit`), fronted by a
+real `ws://127.0.0.1:<port>` relay. It exists so a client that is **not**
+JavaScript — the Rust `client-runtime`, today; any future native client —
+can be tested against the real bridge protocol over a genuine socket,
+without a language-specific FFI shim. See the migration plan §4 "Layer 2".
+
+This is a devtool: it is never published, never shipped, and carries no
+production code path. `packages/testkit` stays a pure library; this package
+is the "spawn it as a subprocess and drive it" layer around it.
+
+## What's inside
+
+- `relayServer.ts` — a thin `ws://` wire adapter over
+  `@codedeck/testkit`'s `InMemoryRelay`. Speaks `REQ`/`CLOSE`/`EVENT` in,
+  `EVENT`/`EOSE`/`OK` out. No NIP-42 challenge is ever issued.
+- `harness.ts` — the "world": one `BridgeCore` + `FakeSdkFacade` + relay
+  server, in a throwaway temp `sessionStateDir`. `restart()` shuts the
+  current `BridgeCore` down and starts a fresh one with the same identity,
+  storage, and state directory — a real bridge-process restart, not a reset.
+- `control.ts` — pure request → response dispatch over a `Harness` (no
+  process I/O — unit-testable on its own).
+- `main.ts` — the process entry point: starts a harness, then reads
+  newline-delimited JSON commands from stdin and writes newline-delimited
+  JSON responses to stdout.
+
+## Running it
+
+```bash
+node out/main.js [--port=<port>]   # 0 (default) asks the OS for a free port
+```
+
+The first line on stdout is always:
+
+```json
+{"type":"ready","wsUrl":"ws://127.0.0.1:54321","pid":12345}
+```
+
+A driver must wait for this line before doing anything else — the relay
+socket is not listening until it's printed.
+
+## Control protocol
+
+One JSON object per line, both directions. Every request carries an `id`
+(any string the driver chooses); the matching response echoes it back, so
+responses may be correlated even if a future version answers out of order.
+
+**Request → response**, one pair per command:
+
+| `cmd` | Request fields | `result` on success |
+|---|---|---|
+| `get-relay-url` | — | `{ url }` — same as the `ready` line's `wsUrl`. |
+| `open-pairing-window` | `opts?` (`PairingWindowOptions`, minus the callbacks — see below) | `{ url, displayUrl, token, expiresAt }` — `expiresAt` is an ISO-8601 string. |
+| `emit-sdk-message` | `sessionId`, `message` (an `SdkMessage`) | `null`. Pushes `message` into that session's stream, as if the Claude Code subprocess had emitted it. The session must already exist (created via a real phone `create-session` command over the socket) or this throws. |
+| `list-sdk-sessions` | — | An array of session ids, in creation order — the same ids the phone sees on the wire. A driver that just sent `create-session` can safely take the last one. |
+| `get-bridge-transcript` | `sessionId` | An array of `{ seq, entry }` — every row the bridge has stored for that session, in order. `[]` for an unknown session. |
+| `restart-bridge` | — | `null`. Shuts the current `BridgeCore` down and starts a fresh one — same secret key, same storage, same on-disk transcripts, but a FRESH `FakeSdkFacade` (a real bridge restart kills the underlying Claude Code subprocess too). `BridgeCore`'s own resume-on-boot re-spawns any still-tracked session under the same id on the new facade. The relay server and its socket are untouched, so a connected client sees a real disconnect/reconnect, not a torn-down world. |
+| `drain-logs` | — | An array of `{ level, message }` — every host log line since the last drain (own or the previous command's). Logs are queued regardless of whether anything reads them. |
+| `shutdown` | — | `null`, then the process exits. Also triggered by stdin closing (the driver process died) — the harness never lingers as an orphan. |
+
+`PairingWindowOptions` here omits `onPaired`/`onClosed` (they're callbacks —
+meaningless across a process boundary); a driver that needs to know when a
+phone paired should poll `drain-logs` or simply proceed once its own
+`pair-ack` arrives on the socket.
+
+**On error**, any command instead answers `{ id, ok: false, error }` (a
+string) rather than throwing across the boundary. A response for a request
+that failed to parse as JSON at all answers with `id: "unknown"`.
+
+## Driving a scenario (sketch)
+
+1. Spawn the process, read the `ready` line for `wsUrl`.
+2. Point a client (Rust `client-runtime`, or a TS test) at `wsUrl` as its
+   relay.
+3. Send `open-pairing-window`; feed the returned `url` to the client's
+   pairing intent.
+4. Drive the client to create a session (a real `create-session` phone
+   command over the socket — the harness does not fabricate sessions).
+5. `emit-sdk-message` to script the fake subprocess's output; assert on
+   what the client observes.
+6. `get-bridge-transcript` to compare the bridge's own record against the
+   client's.
+7. `restart-bridge`; assert the client's reconnect + sync-gap-refill path.
+8. `shutdown` when done.
+
+This is scenario A of the migration plan's Layer 2 gate (pair → session in a
+folder → live output lands in the transcript → input reaches confirmed →
+bridge restart → reconnect → refresh + sync gap-refill → contiguous
+transcript identical to the bridge's own).
