Pins CCmuxAppFFI to cmux-app-ffi-b24aac2c507d072ac3b5cf35fb3c3b93bd039acf (checksum 5aa92a5b76b173dce2a254ab9e437c0b086d3b4d07fd9754ab3d72b0f14b9481), published by run https://github.com/manaflow-ai/cmux/actions/runs/41899051904, which checked it with check-app-ffi-pin.sh --verify-release. A newer publish updates this branch.

Review (independent review subagent): SHIP at acccfaa

What I checked (read-only; nothing was built or run locally):

Diff: one file, Packages/macOS/CmuxNext/Package.swift. Only the CCmuxAppFFI url and checksum change (2 lines in, 2 lines out). The PR head's parent is 7dd3f2e99015 on feat-cmux-next; git diff feat...head shows only this file.
Release cmux-app-ffi-b24aac2c507d072ac3b5cf35fb3c3b93bd039acf exists (prerelease, not latest). SOURCE_SHA is b24aac2c507d072ac3b5cf35fb3c3b93bd039acf. SHA256SUMS and CCmuxAppFFI.xcframework.zip.sha256 both say 5aa92a5b76b173dce2a254ab9e437c0b086d3b4d07fd9754ab3d72b0f14b9481, and GitHub's asset digest of the zip is the same value. That is the pinned checksum.
b24aac2c507d is the merge commit of cmux-rd: one typed app line for cmux rd serve|connect, read back through a C line reader (ABI 5; Mac Screen step A) #35828 (cmux-rd app line reader, ABI 5) and is on feat-cmux-next.
Release run 41899051904 (push of b24aac2c507d): all four jobs are green (build xcframework, Linux cross-compile shadow, publish release, open the re-pin pull request). The re-pin job logs "app FFI pin: sources match b24aac2..." and "app FFI pin: release built from b24aac2... with checksum 5aa92a5b...", which is the check-app-ffi-pin.sh --verify-release output.
Freshness: check-app-ffi-pin.sh --list-inputs at the feat tip gives 15 crates plus cmux-tui/rust-toolchain.toml and scripts/cmux-next/build-app-ffi.sh. git log b24aac2c507d..origin/feat-cmux-next -- <inputs> is empty, and the PR head's inputs equal those at b24aac2c507d. The pin is not stale on arrival.
The new binary brings in two FFI source changes that are already merged on feat: R-INPUT S2b (FFI step A): the app's one input handle cmux_input_* over the input router, with no copy per focus event #35641 (cmux_input_*, layout reducer header) and cmux-rd: one typed app line for cmux rd serve|connect, read back through a C line reader (ABI 5; Mac Screen step A) #35828 (CmuxRdLineReader, CMUX_RD_FFI_ABI_VERSION 4 to 5).
Swift ABI users: the only Swift check is RbClient.swift:31, assert(RemoteRdCore.abiVersion >= 2, ...), so ABI 5 passes. No Swift code calls cmux_rd_line_reader_* yet (cmux-rd: one typed app line for cmux rd serve|connect, read back through a C line reader (ABI 5; Mac Screen step A) #35828 is step A; step B follows this re-pin).

Checks on this head:

"cmux-next checks" is green, including "Check the app FFI pin" ("sources match b24aac2", "release built from ... with checksum 5aa92a5b..."). On the base, the same pin check reports drift from the old pin df4352d75349 (push runs for 036f8aa53845 and b24aac2c507d), so this PR fixes that base red.
Compile checks pass: "cmux-next app compile (build fleet)", "cmux-next fleet Release compile", "cmux-next/compile", "fleet/test-compile (advisory)". "risk evidence", "fast gates" and "cmux-next CI guard group" pass too.
No red check. Still pending when I posted this: "cmux-next swift test", "cmux-next daemon tests", "cmux-next fast tier", "nightly-guards / workflow-guard-tests / release-notary". I did not wait for them. The nightly-guards check was a base finding on cmux-next: pin CCmuxAppFFI to cmux-app-ffi-df4352d75349a4374f29caac31458c83d4a0c6dc #35420 and this PR changes no workflow.

…he app's one input router (cmux_input_*) (#35875) * cmux-next: pin CCmuxAppFFI to cmux-app-ffi-b24aac2c507d072ac3b5cf35fb3c3b93bd039acf * R-INPUT S2b step B: every window's focus machine keeps its focus in the app's one input router (cmux_input_*) Step B of the FFI two-step (step A #35641, re-pin #35853): FocusMachine calls the input handle (`cmux_input_focus_*`, one window key per machine) instead of a per-window `cmux_focus_*` handle. The router is made once at the composition root (AppServices.focusInput, FocusInput in CmuxNextFocus) and given to each window's FocusCoordinator through WindowState. Pure refactor: the same requests and the same reply bytes (step A's corpus test), so every focus rule is unchanged. - FocusInput owns the CmuxInput handle (memory: the Mac's physical memory, which bounds the key lanes). Each machine opens a window under a key no other machine of that router had, and closes it when freed, so a window id the app reuses (a restored closed window) never meets the state of the machine it replaces, whichever is freed first. - A machine made with no input (tests, the journal replay) gets a router of its own. - FocusMachine's Close Tab aim calls move to FocusMachine+CloseAim.swift (A12 follow-up); the file shrinks from 467 to 458 lines. - FocusResponderClassifier.describe moves to the package as FocusEvent.Responder.debugName (CmuxNextApp: -10 lines). Tests: FocusInputSharedRouterTests: a machine in the shared router reduces exactly as a machine alone (state and effects after every event) while another window acts between its events; a new machine never meets a freed machine's focus; every request goes through the input handle (the close-focus policy, the Close Tab aim, the history, the remembered panes, the checkpoint; a checkpoint that does not decode is refused and leaves the state as it was: review notes of #35641). * FocusInput: the memory default is read in the init (a default argument may not name an internal import) * test(focus): the input-handle request test follows PaneCloseAim's documented order (the focus moves, then the frame shows) and compares each answer with a machine alone --------- Co-authored-by: manaflow-cmux-ffi-release[bot] <339941766+manaflow-cmux-ffi-release[bot]@users.noreply.github.com>
