It stamps each scripted step on a virtual clock and writes the cells the step changed, as pyte saw them, so the same input makes the same file. The petscii cast generates its Mandelbrot views and reads the Intel SDM (--pdf) through a symlink. Co-Authored-By: Claude Opus 5.5 <[email protected]>

Under `9ns --unix` the mount is the server it dialled, never this session (its socket does not exist until it starts), so it stays unset there; scripts fall back to `9p -a "unix!$PARDES_9P"`. Nothing is statted: the name comes from the session's socket and the environment. selfmount checks both modes. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* `> exec` through a mount no longer hangs the editor, and a close holding a ↵Gabriel Schneider4 days
| | | | | | | | | | | | | | | | | | last line is answered at once: the line runs at the editor's next step A shell's truncating open of exec (or look, ctl, log, pager) sends a setattr that changes nothing; it waited for the editor to be quiet, and through a 9ns mount that quiet could never come: 9ns answers nothing else on the mount while the setattr is out, and the editor's step may be out reading a pane's file through it. This was the "truncating open of exec hangs, only in selfmount" mystery. Only a truncate of a pane's file or a tag waits now. A close holding a last line with no newline hands it to the editor's step (tree.runClosedLines, beside fillClosedPagers), as a /pager close does, and is answered at once; a refusal is the log's err.

* A look at a path not there under a peer's mount is a miss, the write ↵Gabriel Schneider4 days

* An exec or Tty from a pane whose directory is a peer's path refuses before ↵Gabriel Schneider4 days
| | | | | | | | | | | making any pane: `exec: <dir>: no such directory`, no `exit 127` pane left A peer's directory (`/n/peer/x`) is no directory on this host, where the shell starts, so a command there ran in a pane that could only say `(pwd) exit 127`, and a Tty made a new/del pair. missingDir now counts such a path missing, as it does a local directory that is not there.

* A command line runs when its newline comes, or at its open's close, never ↵Gabriel Schneider4 days
| | | | | | | | | | | | | | | | because a write was short: a long line cut by a mount is one line A write shorter than its message, and not a multiple of 4096, was taken as whole, its tail a line. 9ns cuts a FUSE write of up to 512 KiB into 65512-byte Twrites, the last one short, so a 600 KiB `Edit ,c/.../` arrived cut and its tail ran as an unknown control message; the 1 MiB refusal failed the same way. Each open now holds a partial line until its newline, or its release, which ends the last line; an Edit block is whole when it closes, as before. A name write with a NUL still fails its write at once. selfmount writes a 600 KiB Edit line and a 1.1 MiB line through a real 9ns mount; building.typ says how lines are cut.

* Shift-Esc always backs out: in every mode and pane it goes to the previous ↵Gabriel Schneider4 days
| | | | | | | | | | | | | | | pane, as Esc does from normal, and a raw program never sees it; Ctrl-b alone toggles raw Shift-Esc switched a terminal in normal or insert mode into raw, so the one key meant to get out of anything got a script or a person into a program instead. It is now handled before any mode: an open prompt is closed, insert mode left, a pending count dropped, and Last runs, the pane keeping its mode (a raw terminal stays raw). Ctrl-b is the only switch between raw and normal. The keymap's two chords become one, back_out; the cheatsheet row, the guide's mode table and the tutor say so, and the tty and builtins goldens are re-recorded.

| | | | | | | | | | | | or a script's EDITOR) asks that session and waits there, not a screen of its own Forwarding asked for $PARDES_PID and $PARDES_PANE, which only a pane's shell has, so a client that talks to a session from outside its panes got a full editor drawn in its terminal.

The ctl read ends with `collapsed` when it is, and a PDF's `fit:` and `tint:` in the words PdfFit and PdfTint take; the dump's image record carries pdf_fit and pdf_tint (empty in older dumps: the defaults).

* A PDF place `:P:H` whose search hit H is not on page P, or with no search, ↵Gabriel Schneider4 days
| | | | | | | | | | | | | is a miss with an err, as a page past the last is The second number of a PDF place is a hit of the pane's search (its search rows are `file.pdf:P:H`), and one that named no hit turned to page P silently. pdf State.hitExists asks the pane's search for page P: a hit it does not have, or any hit with no search, is now `<file> has no search hit H on page P`, on the pane itself (`:P:H`) and from anywhere (`file.pdf:P:H`); a search row's hit is always there.

* Restore reads a clean file from disk, and an unsaved one whose file changed ↵Gabriel Schneider4 days
| | | | | | | | | | | | | | | | | | | | | since the Dump is said changed, its first Save asking before overwriting it A Restore put back the dump's copy of every file pane and armed the watch with the disk as it now was, so a file changed on disk after the Dump came back as its old text, marked clean, and the next Save wrote the old text over the new without a word. A clean file pane's text is now not in the dump: Restore reads its file (an older dump's copy is read past too, and used only when the file is gone). An unsaved pane keeps its text once, base64, the plain copy beside it dropped, with the hash of the file it was read against (`disk_hash`); a Restore that finds another there says the file changed on disk, and Save asks once before overwriting it, as for a change seen while it was open. file_watch.zig's own tests were never collected (no test root imported it): main.zig's test block does now, and the restored watch test says what a clean restore now reads.

* A file name with a newline is refused naming it once: `pardes: ↵Gabriel Schneider4 days
| | | | | | | | | | two\nlines.txt: a file name is one line...`, not `a file name: a file name ...` The refusal's subject was the words "a file name", and its reason began with them again.

| | | | | | | | | | restored terminal draws its graphics as glyph art again An image pane's Petscii choice was dumped; a terminal's was not, so a Restore brought it back drawing pixels. dump.Terminal carries petscii, and a restored terminal is turned to glyph art when it was.

* `:N:H` looked at on a PDF pane turns to page N, as `book.pdf:N:H` does from ↵Gabriel Schneider4 days
| | | | | | | | | | anywhere, not a refusal that a PDF has no text A PDF's own pane took only `:N`; `:5:3` was refused as no text to address while `book.pdf:5:3` turned to page 5 (its search hit 3). lookPdfPage now reads the page before a colon and the hit after it. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A Rename, references and the like tell the server of every open file of its ↵Gabriel Schneider4 days
| | | | | | | | | | | | | | | | language first, so a rename reaches files it had not seen and the preview lists them zls renames only in the documents in its store, and syncDoc told it of a file only when a query was asked from it, so renaming in progress.zig left main.zig unchanged and broken, with no preview. For a query whose answer can reach other files (rename, references, implementation, workspace symbols, calls and type hierarchy), the host snapshots every other open file and the client syncs those its server answers for first. The mock server answers a rename in each document it was told of; lsp-rename-files opens main.rs by a look, renames from lib.rs, and its preview lists both.

* A name under a directory that may not be searched or written is refused, ↵Gabriel Schneider5 days
| | | | | | | | | | | | | | permission denied, and a Save there says so, not no such directory `pardes noperm/a/b/c` and `pardes /proc/1/root/x` took the missing directory for one Save would make, opened a pane and exited 0; its Save then said "no such directory". fs.deniedAbove finds the nearest directory there and asks whether it may be searched and written: forwarding refuses such a name, exit 1, "permission denied", and a failed Save says "permission denied", which the writer's 9P error carries as EPERM (9ns: EACCES).

* --wait waits on the pane its look answered, read on the look's own open, not ↵Gabriel Schneider5 days
| | | | | | | | | | | | | one found again by name in /index The forwarded look was a write and nothing more, and --wait then looked its file up in /index. /index shows names escaped (`\\` for a backslash, `\xNN`), so a file named with one matched no pane and --wait exited 0 at once, as if the pane were already closed. The look is now asked on one open (Client.ask) and its answer is the pane waited on; /index by name stays only for a look that answers none. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* pardes - asks /pager for its +Pager and reads the serial on the same open: ↵Gabriel Schneider5 days

Client.ask writes and reads on one open. The README's look recipe reads its answer on its own open too. Co-Authored-By: Claude Opus 5.5 <[email protected]>

| | | | | | | | | | | | size or a nominal 8x16 before one attached forkShell sized a new pty in pixels (ptyWinsize), but the detached server's resize set xpixel and ypixel to 0, and a pane is resized as it is placed, so a program in a detached session with no frontend (yazi) saw a pty with no pixels and drew no images. CSI 14/16/18 t were already answered at the nominal 8x16 cell. Co-Authored-By: Claude Opus 5.5 <[email protected]>

* pardes - writes the whole text through one open of the body, so a page over ↵Gabriel Schneider5 days
| | | | | | | | | | | | | | | 8 MiB arrives whole, not as its last chunk Each 8 MiB chunk went in by its own Client.write, which opens a body with OTRUNC, so every chunk replaced the one before and a long page kept only its tail, with exit 0. The text now goes in through one open, truncated once and written at rising offsets; a long write is timed by its progress, each 9P write answered within 30 s rather than the whole transfer within 2. fs.py pages 11 MiB of numbered lines and compares the body byte for byte, and pages past the 256 MiB cap and checks the first 256 MiB and the cut note.

* pardes - keeps one +Pager per directory, refilled, named so from its first ↵Gabriel Schneider5 days
| | | | | | | | | | | | | | | | | | | log record; streams the text in bounded writes; never loses it; handles \r, NUL and BEL as a terminal does Each paged command made another +Pager until placement failed, and then git's text was lost with exit 0; a 130 MB page timed out half written and dirty; a directory whose name held a newline left a stray +New; and the log said new +New then rename. The root ctl's `pager <dir>` now makes the directory's +Pager (named before it is announced, placed without the keyboard) or empties the one there; the text goes into it a line-ended 8 MiB chunk a write, one undo step, up to the file limit and its note, and is left clean. A directory a ctl line cannot name pages into the session's. Any failure prints the text to stderr with why and exits 1. A carriage return keeps a progress line's last state and CRLF is a newline; NUL, BEL, SO and SI go; empty stdin makes no pane. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* With Pager pardes, a terminal's shell also gets SYSTEMD_PAGER and ↵Gabriel Schneider5 days
| | | | | | | | | | | | | | SYSTEMD_PAGERSECURE=0, and the pager's path is quoted only when it needs it journalctl and systemctl read SYSTEMD_PAGER, not PAGER, and in their secure mode run only less, so a pty/run of either still waited in it; and systemd, splitting a pager on blanks and exec'ing it, never ran the quoted path. Where the user's environment sets neither, a terminal now gets SYSTEMD_PAGER as PAGER is set and secure mode off (this pager has no shell to escape to), and the path is single-quoted only when it holds a blank or shell character. Command panes keep cat. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* An event record is delivered in pieces to reads shorter than it, so a bash ↵Gabriel Schneider5 days
| | | | | | | | | | | | | read loop on event works A read shorter than the record waiting was refused EINVAL, and bash's read, a byte at a time on a file it cannot seek in, failed on the first record. A short read now takes the record's front and the next read the rest, as log and pty/data already did and acme allows. A unit test reads two records a byte at a time; selfmount runs a bash read on event through the mount. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A bare :N or :N:M look addresses the pane itself, its line N (column M), ↵Gabriel Schneider5 days
| | | | | | | | | | | | | from every way a look comes; a PDF's :0 has no page 0 A look of `:12` had no path to resolve, so it fell through to a word search for the text ":12" and found nothing. A digit-led address with no path now names the looking pane, as `:/re/` already did: its look, the root's (the keyboard's pane), Look, B3 and an event write-back all reach it, a terminal's logical lines included. On a PDF, :0 is the has-no-page miss rather than a refusal. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A terminal pane draws the kitty graphics its program places, so yazi's image ↵Gabriel Schneider5 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | and PDF previews show yazi asks the pane XTVERSION, and ghostty-vt answers "libghostty": yazi takes it for Ghostty and sends its previews by the kitty graphics protocol with Unicode placeholders (a=T,U=1, then U+10EEEE cells). ghostty-vt stored the images, but nothing drew them: the placeholders showed as tofu in the GUI and as raw codepoints in the tty, in every build since terminal panes answered queries (vkznsvzs, 2026-07-01). Before that no query was answered and yazi fell back to chafa's text art. Each frame, TerminalImages.zig reads the active screen's images and placements (virtual ones through their placeholder runs, and ones placed on a cell), cuts each into the cell rows it covers, maps those rows through the body's own row walk, clips them to the pane, and hands them on as ImagePlaces with exact geometry (NativePlacement.exact). The GUI draws them as textures; the tty passes them to an outer terminal with kitty graphics as one placement per row, its source cropped to whole cells. Placeholder cells draw no text. Scrolling, a delete, a resize, the alternate screen and a closed pane all fall out of reading the emulator's state every frame. A pane now knows its size in pixels: CSI 14/16/18 t are answered, the emulator's width_px/height_px follow the shell's cells, and the pty's winsize carries pixels (host_io.ptyWinsize), so yazi and a nested pardes size their images right. ghostty-vt's image store is 64 MiB per screen (its library default, 10 MB, refused a large preview), PNG transmissions are decoded with stb_image, and RGB images are converted only while shown. test/yazi_preview.py runs yazi in a hidden window on a PNG and a PDF and checks the captures, also through a tty pardes nested in the pane.
