* feat(mobile): RN bridge host for the web shell page (OTA phase C, C0.3) One page document's end of the bridge: page frames in through the C0.1 reader, one RpcClient behind it, host frames out. Requests forward with the arity the page used and answer with the verbatim RpcResponse, chunked when it is over the frame cap; a rejection crosses as the five-field capture instead. Subscriptions carry a seq and an unacked window, and end with `overflow` rather than dropping frames a reader cannot see are missing. The fence is structural: the protocol names no host, so the client is whichever this host was built with, and the in-flight caps the page is told about in `init` are enforced here rather than trusted from there. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * feat(mobile): wire the bridge host to B4's hybrid shell screen (OTA phase C, C0.3) The channel opens on the session B4 put on screen and closes with it. The session id is B4's: nothing new is minted, and a remount is a new one, which is what makes a dead page's frames fail the native origin check. Both halves are stamped with the session they belong to, because React swaps refs during the commit and runs the retiring effect's cleanup after it — a host disposing on a remount would otherwise post its teardown into the page that replaced it. `bridgeEnabled` is derived from the session step alone, since the native side treats a prop change as a reload. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * test(mobile): prove the bridge fence holds for traffic, not just for answers A mutation that dropped the post-teardown guard in `receive` survived: the teardown case only fed a frame whose answer the outbound guard already swallowed, so nothing observed that a dead page could still reach a live client. Both teardown paths now feed a request, a subscribe and a notify, and assert the client saw none of them. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * test(mobile): read the hook's frames through the page's own reader `JSON.parse` returns `any`, and taming it with an assertion is a cast the gate refuses and a check nobody gets. Reading each posted frame through `readBridgeHostMessage` types it and proves the same thing the host's own suite does: a frame the page would refuse is a frame that never arrives. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * chore(mobile): list the bridge host as a raw request port owner The boundary ratchet reads a `.sendRequest` access as a call site, and the host has three: one per arity the page can use. It is not a call site. It picks no method, reads no reply and decides no acceptance — the page names the method and runs the typed operation over the client this carries, which is what the C0 design put page-side so `runRpcOperation` stays unchanged there. That makes it an owner, beside the socket and relay senders, not a migration backlog entry. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * test(mobile): prove a stream that overflows inside subscribe is unsubscribed A client that emits synchronously from `subscribe` can retire a stream before its unsubscribe exists to be stored. The identity check that calls it instead had no test; deleting it left the suite green while the client's stream leaked. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * fix(mobile): hand the bridge host over in the commit, not after it A client swap that keeps the session id leaves the handler's own fence inert: until the passive effect ran, a native frame reached the retiring host and the client it closed over. A layout effect swaps both inside the commit. Teardown on unmount now runs while the view is still attached, so a pending request is answered delivery-unknown instead of being dropped on the floor. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * fix(mobile): hold a refused page frame to one warning per page A page that sends one bad frame usually sends many, and a line each buries the first — the one that says why. Same bound the host already keeps on a failing post, applied per kind and reset when a new page gets a new host. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * fix(mobile): bound the page's terminal viewport at the bridge contract A viewport crossing the bridge is written into the cached subscribe params of every stream naming that terminal, including the native terminal screen's, and the desktop refuses cols over 1000 or rows over 500 when those streams resubscribe. Unbounded, one page could kill streams it never opened; the frame is refused instead, and the bound is pinned to the desktop's own. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * fix(mobile): stop the page's close from latching the bridge host shut One view carries every document the shell loads, so the page that says `close` is not the last one. A latched host dropped the next document's `ready` in silence, and a page that re-sends `ready` on a backoff would retry forever with nothing posted and nothing logged. Close now cancels what the page owned and leaves the host live; only dispose shuts it, and a frame arriving after that is diagnosed rather than dropped. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * fix(mobile): keep a throwing client or post inside the bridge host The `state` frame is sent from inside the client's own state-change fan-out and a notify runs on the native event handler that delivered the page's frame, so a synchronous throw from either escapes into a loop the bridge does not own and takes unrelated listeners with it. Both are fenced and reported once. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * test(mobile): prove an ack releases the stream's unacked bytes The frame window reopens on ack through the splice, so deleting the byte release left every existing test green while a long-lived stream of large frames would end with overflow on its first frame after an ack. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * fix(mobile): pass the commit-window harness its children as a prop `createElement`'s variadic children do not satisfy a props type that declares `children`, so the file dropped out of the tests typecheck ratchet. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * fix(mobile): render the harness from the commit-window wrapper, not as children A props type that declares `children` is what `createElement`'s variadic form does not satisfy, and passing it as a prop instead trips the react rule. The wrapper renders the harness itself, which is the parent position the layout effect ordering needs anyway. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * fix(mobile): pin the desktop viewport bound by reading it, not importing it Mobile may not pull an rpc-contract *value* into its bundle, and the boundary test that enforces that scans this test file too. The pin reads the schema's own source instead, so drift in either bound still fails loudly. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * fix(mobile): serve the bridge to one document at a time A page's `close` now ends that document's turn: until the next `ready` claims the view, every other frame is dropped and diagnosed instead of reaching the client, and nothing is posted. Without the fence a straggler from the closed document was still forwarded, and a `state` frame from the still-running client landed in the replacement document before its `init`. Claude-Session: https://claude.ai/code/session_01JNnE9qzUZMMnqpZWCqM3nb * fix(mobile): hold the request cap against the calls, not the page's ledger `sendRequest` has no cancel, so a request the page cancelled or closed out keeps running on the desktop until it answers. The cap now counts those calls until each settles; counting the pending map let a page interleaving `close` with batches hold many more than the cap `init` advertises.
