* fix(mobile): replay a delivery-ambiguous worktree.create instead of failing it A socket close or response timeout rejects an in-flight worktree.create as delivery-unknown: the frame reached the wire, so the host may already have built the worktree. The client only replayed connection-migration cutovers, so every other ambiguity surfaced as a create failure for a create that may well have succeeded. Replay on the same clientMutationId — which the host already dedupes — after waiting for the transport to come back. * fix(mobile): bound the ambiguous worktree.create replay by the host's dedupe window The replay was bounded only by a retry count, but what makes a replay reconcile instead of building a second worktree is wall clock: the host drops a settled create's dedupe record 60s after it resolves, and past that the replay is just a fresh create that the host's suffix loop happily duplicates — for a folder workspace, into a second workspace with the very same name and no collision check at all. Two paths ran past that window: - The request-timeout path. A silently dropped response frame leaves the socket alive, so nothing rejects until WORKTREE_CREATE_TIMEOUT_MS — ten minutes, with no bound at all on when the host actually resolved. This was previously the path that replayed *soonest*, short-circuiting the reconnect wait because the transport still looked healthy. Invert it: every path that reports a real drop has already left 'connected' by the time the rejection surfaces, so still being 'connected' identifies the timeout and is now refused. - The reported-drop path. Worst-case detection is a full liveness idle period plus the missed-probe budget before the client even learns the socket is dead, and the old 20s wait on top of that overran the record. Derive the wait from the watchdog constants and the TTL instead of hardcoding it, and anchor a single deadline at the first ambiguity so a second wait gets the remainder rather than restarting. The TTL now has one definition shared by both processes, so the client asserts its budget against the host's real window instead of a copied literal. * fix(mobile): end the reconnect wait on a revoked pairing, and pin the wait's behavior waitForRpcClientReconnected resolves only on 'connected' or the timeout, but an 'auth-failed' client never reaches 'connected' — so a create interrupted by a revoked pairing sat out the full wait before surfacing the error it already had. Treat auth-failed as a terminal answer on both the fast path and the listener. The helper also shipped with no tests of its own: its already-connected fast path, its timeout path, and the synchronous-notification-during-subscribe teardown were only ever exercised indirectly through the retry suite, and neither RpcClient implementation notifies synchronously, so that branch had no coverage at all. Add a direct suite covering all of them, asserting listener and timer teardown rather than just the resolved value. Also give the fake-timer tests an explicit timeout. advanceTimersByTimeAsync yields through real macrotasks between ticks while vitest's own budget runs on real time, so on a loaded runner the default 5s is reachable — observed once as a spurious timeout in this suite. * fix(mobile): bound the ambiguous replay in wall clock, not timer time The replay window was derived from the liveness watchdog's own budget (idle + missed probes x probe timeout). That is a bound on how long the watchdog takes to *fire*, not on how much wall clock passed. iOS and Android suspend JS timers while the app is backgrounded, so across a background cycle the socket dies silently and the pending create rejects delivery-unknown minutes later with the timer-derived ceiling still reading ~44s. The replay then lands well past the host's 60s dedupe record and the suffix loop builds a SECOND worktree - for a folder workspace, one with the very same name and no collision check at all. Anchor the deadline on the watchdog's lastInboundAt instead: a wall-clock stamp of a frame that really arrived, so it stays honest across a suspension. Fall back to the send time when the transport can't vouch for one (relay sessions run with idleProbeMs: null), which errs toward refusing the replay. Also restore the delivery-unknown discrimination test that the still-connected guard had made vacuous, pin the still-connected guard itself against a live inbound stamp, and pin the deadline against being re-read from a fresher replacement session.
