Alt/Option-click is B2 and Super/Cmd-click is B3, sweeps included, as in plan9port: a one-button trackpad can execute and look

2026-10-01T15:58:23Z

The core decides it at the press (mouse.emulateButton) and keeps it to the release, whatever keys are let go between. Ctrl-click stays a definition, and a program tracking the mouse still gets the plain click (Alt as its meta, Super as nothing). The SDL, macOS and web shells now pass Super; the macOS and web shells pass Alt on a click too. A terminal's mouse report has no Super bit, so in a terminal only Alt-click is B2.

A pty/ctl exec that cannot start its shell keeps the one running

2026-10-01T03:12:16Z

Each host closed the running shell before it forked the new one, so an exec whose shell failed left the pane with none and later runs answered error shell gone. A shell not there is now refused up front, and every host starts the new shell first, replacing the old only once the close-on-exec pipe says it ran; a failure there is only said (restartFailed).

A shell given a directory is not taken to be in this process's before it has spoken, so it logs no rename to the session's and back

2026-10-01T03:12:16Z

Each host read /proc//cwd right after forking the shell and at every frame after; before the shell's chdir that says this process's directory, a rename to it, then the real one a frame later, a rename back. A shell given a directory is named by it already (newShell) and is no longer asked at fork; and until it has printed anything, an answer naming this process's directory is not taken.

Tty in a missing directory fails and makes no pane; a shell that never started answers runs

2026-10-01T03:12:16Z

The host could not start the shell (its chdir failed), and the pane stayed with no pty: a run written to it waited for a prompt for ever. Tty now refuses a directory that is not there, `Tty: : no such directory`, before making a pane; and a terminal whose shell the host could not start (Pardes.shellFailed, from each host's spawn) answers any run with `error shell gone`.

G7: a moving pane casts a shadow, a retargeted move keeps its speed, a dissolve crossfades

2026-10-01T03:12:16Z

- Track.launch: a move retargeted mid-way (Presentation.sync) starts at the old move's speed along the new one's longest side (carriedLaunch, Motion.easeFrom/speedFrom), so a second change during a slide bends the motion instead of stopping it dead. The macOS track ABI grows the float (pardes.h, 48 bytes; its reserved byte is named motion, as in Zig). - A pane that slides, zooms or rises casts Lift's soft shadow at sin(pi x progress) of its strength, on the other panes' bodies and rails alone, under the same contrast ceiling, carried by its track. - The GUI's PanelDissolve is a crossfade: the new cell drawn first, the old one over it at 1 - progress, premultiplied, on the blending cell pipeline for such groups (new cells now emitted before old ones, as the old layers already came after the new). sRGB blend, not linear light (documented). The tty keeps its per-cell swap. Presentation.zig's and animation.zig's tests were not in any test root; pardes.zig's test block now takes them in. Tests: a retargeted move carries its speed and still lands exactly; a moving pane's shadow is clipped off every tag, grip and its own body, none at the start or the landing, most mid-way. GUI golden 18 changes by the shadow (frame 6 of a slide). Gates as G6. Feel review: .scratch/render/transitions/.

A failed Dump or a Restore of no dump fails its write, before any warning

2026-10-01T03:12:15Z

A Dump into a DumpDir it could not write, or a Restore of a file that is not a dump, answered a ctl write with rc 0 and only a message, and the Restore warned about unsaved panes before it ever looked at the file. The hosts' dump write now fails the waiting 9P write with EIO (the late failure a Save uses), naming the path and the reason in the log, and Restore parses the file before its unsaved-panes refusal, failing with `not a pardes dump`.

Motion flavours differ by design, and drive notice drops and pane moves

2026-10-01T03:12:15Z

The flavours looked alike because Lift, the only motion that read them, moves a shadow a few pixels: overshoot and wind-up were sub-pixel. By design now: crisp leaves at full speed and never passes its mark; smooth (the default) eases in and out in twice crisp's time, a slide arriving in 208 ms (inside §8.1's 220); bouncy passes its mark by ~30% and settles twice; playful winds up, passes by ~40%, and stretches and squashes, text included (the user's choice). Small motions are exaggerated by the flavour's gain. Motion gains launch, gain, span and norm, and ease(u)/speed(u) for moves of fixed length. The notice drop follows ease() over its fall (alpha never behind its position) and stays inside its pane's body past its row. Panel tracks carry the flavour in Track.motion (the old padding byte; macOS header name follows); opening and moving slides, zooms and rises follow it over span x their frames; landed, a pane is exactly its target; closing keeps its own exit. A pane past its mark never takes a neighbour's click; a rising one stays in its box. Tests: each flavour's lift trajectory distinct; flavour character; exact landing bit for bit; a stretched pane's drawn cells map back; the overshoot hit rule; the vertical clip at peak; legacy tests pinned to crisp. GUI golden 18-mid-transition changes (the retuned smooth slide at frame 6).

Kill stops a command pane's whole line again, now it runs with job control

2026-10-01T03:12:15Z

With the line run under job control (the change before), the job running has a group of its own, and Kill's SIGTERM to the tty's foreground group stopped only that job: of `sleep 30; touch x` the touch still ran. For a command pane the hosts now signal the shell's group as well, so the whole line stops, as it did; a line typed at a prompt still loses only its foreground job. The test forks a real pty for both halves: a background job outliving its command and the pty's hangup, and a killed line not running on. Co-Authored-By: Claude Opus 5.5

A shell that exits under a run answers exit N, and the log says exit before del

2026-10-01T03:12:15Z

A dogfood agent ran `exit 3` through pty/run: the reader got ENOENT, and the log went straight to del. The hosts now read a shell's exit status at its pty's end as they do a command's; a run waiting on the line answers `exit 3` with what it printed, the log says `exit 3` before the pane's `del`, and an open run still stats after its pane is gone (cat fstats its input). Pins cloud9 f35b7ed, whose stat of an open fid names its open. Writes to a gone pane's pty/data, held open or not, fail ENOENT. Co-Authored-By: Claude Opus 5.5
