* A refusal over unsaved panes keeps its list in +Unsaved and shows a short noticeGabriel Schneider6 days
| | | | | | | | | | | Exit's refusal (and Restore's, Del's, Delcol's, get's) put its full text on a notice that went: a long list of names, gone before it was read. The list now goes into one +Unsaved pane, filled again by each refusal, a row a pane (`<name>: Modified`) and the `Exit again to discard` line; the notice is short, `3 unsaved panes — Exit again to discard`. The 9P `unsaved` records and the write's err are as they were. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* ThemeSel is Themes and FontSel is Fonts; the old words still work in init ↵Gabriel Schneider6 days
| | | | | | | | | | | | files and dumps The user asked for the plainer words. Every use is renamed: the builtins, leader paths, /commands, the docs and tutor, tests, and the themesel golden, re-recorded. An init file's ThemeSel or FontSel runs the new word and says `ThemeSel: renamed to Themes`, as ColumnTags is said; a dump naming an output pane by the old word restores it.

* Recent lists the files opened lately, closed ones too, and a jump back to a ↵Gabriel Schneider6 days
| | | | | | | | | | | | | | | | closed file reopens it A file closed by accident, its path forgotten, could not be found again: the jumplist dropped closed panes. Every file opened (a look, a Save of a scratch, a Restore, a rename) goes first in a list of 200, kept once, its dot noted when it closes, kept across sessions in $XDG_STATE_HOME/pardes/ recent. `Recent` (SPC f r) shows it in a reused +Recent, each row `path:line:col open|closed` a look reopens; /recent reads `open|closed <path>`. The jumplist keeps a closed file's entries, +Jumps marks them `(closed)`, and Back to one opens the file at its place. acme has no such thing; its dump and Load are the nearest.

* A column takes panes until their minimums fill it, not until none can be halvedGabriel Schneider6 days
| | | | | | | | | | Placement halved the tallest pane or refused, so 11 panes filled 48 rows that hold 16 at their tag and two rows each: the refusal did not match the documented arithmetic. When no pane can be halved but the minimums with the new pane's fit, the column's rows are shared out again; and a refused pane's removal leaves no pane under its minimum.

* Find and Grep share one +Search a directory, each run replacing the lastGabriel Schneider6 days
| | | | | | | | | Each Grep with a new pattern opened another +Search, until the column refused panes. Find and Grep now reuse their directory's one, as acme reuses +Errors, and the exec reads back the pane it filled; a plain word's LookWord list search keeps a pane a pattern as before.

* The docs: --detach runs the editor as $!, a line with no newline fails only ↵Gabriel Schneider6 days
| | | | | | | | | | | | in the log, data reads to the end The skill said --detach forks and $! was not the editor's pid; it is, and /status agrees. A line written with no newline runs at the close, after the write is answered, so its failure is in the log alone: end lines with their newline. And `cat data` reads from the address to the end of the text, as acme's does; xdata is the range. Co-Authored-By: Claude Opus 5.5 <[email protected]>

| | | | | | | | | | | | are ENOENT, a GUI-only setting EINVAL A Dump into a DumpDir not there failed EIO `file not found`; `no shell "x"` read as EIO through a mount; and a GUI-only setting on a terminal, EINVAL in the reply, had no word 9ns reads as EINVAL. Each says so in the words that give its errno: `no such directory`, `not found`, `invalid here`. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A bad event record says what is wrong with itGabriel Schneider6 days

| | | | | | | | | | | | refused before running is Failures of a builtin through a ctl quoted the line after the builtin's own words, which already named it (`Mount dead /x: dial failed: no answer "Mount dead /x"`), while the same failure through exec did not. A line that ran says why in its own words everywhere now; only a line refused as no message at all quotes it, as Plan 9's cmderror does. Co-Authored-By: Claude Opus 5.5 <[email protected]>

* A shell that cannot start fails Tty and pty/ctl exec with why, before either ↵Gabriel Schneider6 days
| | | | | | | | | | | | | | answers A shell whose exec failed (a script's missing interpreter) was reported started: Tty and pty/ctl exec succeeded, then the pane died. The child now reports a failed chdir or exec through a close-on-exec pipe the parent reads before acknowledging the shell; the host's spawn fails with the reason (`shell not found`, ENOENT), which fails the waiting write. A Tty whose first shell never ran leaves no pane; a terminal restarted by pty/ctl exec keeps its pane. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A shell started again by pty/ctl exec is guarded against the rename flap as ↵Gabriel Schneider6 days
| | | | | | | | | | | a new one is The guard that keeps a shell from taking this process's directory before its chdir lasted only until the first shell spoke; a shell started again in the same pane (pty/ctl exec) was asked with the old shell's word still standing. A spawn resets it. fs.py's naming test restarts one too. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A tag write refuses NUL and the other control characters; a Dump that fails ↵Gabriel Schneider6 days
| | | | | | | | | | | | says so A NUL written into a tag went into the dump, which the host then could not write, and Dump said nothing: a success that wrote nothing. Tag writes, the workspace's, a column's and a pane's, refuse control characters but tab and newline, DEL, C1 and bytes not UTF-8, EINVAL; and Dump reports any failure of its own instead of swallowing it.

* A served-tree pane spoils no Grep, and `look .` from a gone directory is ENOENTGabriel Schneider6 days
| | | | | | | | | | | A pane named `/virtual` gave Grep the root `/`, which swallowed every other pane's directory and ran out of walk before any file: every Grep missed. Grep passes over panes of the served tree. And `.` from a pane whose directory was gone resolved to the served tree's root (/virtual/), or through the jump list to another pane's directory: a dot path is the looking pane's own, and gone it fails, `look: <dir>: no such directory`.

* Edit written to /tagexec or a column's exec is refused as the other pane ↵Gabriel Schneider6 days
| | | | | | | | | | | words are Edit was let through the pane-word check (the root's ctl takes it at the active pane), so `Edit ,d` written to a tag no pane owns wiped the pane with the keyboard. Every pane-scope word a tag does not hold is refused there now, Edit included; a test enumerates them all. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* fs.py's workflow canary: one session driven as the dogfood agents drive itGabriel Schneider6 days
| | | | | | | | | | | The round-18 Grep that found nothing slipped past every narrower test. One broad run now looks files, runs Grep and Find hits and misses, looks a plain word, Edits two files and Saves them, gets one back from disk, runs pty/run failing then passing, Kills a command pane, sends to a REPL, makes and removes a column, answers an ask, and Dumps and Restores, checking the log and the read-backs at each step, in under 30 s.

| | | | | | | | | | | ENOENT, #100,#50 past the end, --detach forks The one rule's wording left out a pane's pty/ctl and the ENOENT a Find, Grep or missing directory now answers; `#100,#50` in a short text says out of range, its ends checked first; and the skill now says --detach forks, the pid being /status's.

* An err record's reason that names its file already is not prefixed twiceGabriel Schneider6 days
| | | | | | | A refused look logged `err N look: look: no space for a pane...`: the reason began with the file's name, and the record put it before it again. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A Save into a directory that is not there says no such directory, ENOENTGabriel Schneider6 days
| | | | | | | | It failed EIO with `file not found`, which named no file that was missing. It says `Save <path>: no such directory`, and a late failure saying `no such` answers ENOENT, as a builtin's does. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* /index shows names as the log does, one line of UTF-8, and a newline in a ↵Gabriel Schneider6 days
| | | | | | | | | | | | name as \n /index printed a name as it was, so a directory with a newline in it split its row in two, and bytes not UTF-8 went through; the log turned the newline into a space, silently another name. Both now show a name one way: a newline `\n`, other controls, DEL and C1 a space, bytes not UTF-8 `\xNN`. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Every EINVAL a write gets says why; DEL in an exec or look line is a control ↵Gabriel Schneider6 days
| | | | | | | | | | | | character An empty name, a word written to log other than follow, a data, sel, dot or dirty write to a pane with no text, a truncate other than to zero, and a control character in a look line written through a held open were refused with no words, logged as `Invalid argument`. Each says its reason now; and DEL is refused in exec and look lines as in names. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* pty/ctl exec fails the write when the shell cannot start; a directory ↵Gabriel Schneider6 days
| | | | | | | | | | | | | removed under a shell leaves its name `exec` on pty/ctl restarted a shell in a directory that was gone, the write succeeding and the pane dead; and the pane was then renamed `<dir> (deleted)` from /proc, so a restart failed even once the directory was back. `exec` is now refused up front, ENOENT, where the directory is gone; a shell the host cannot start fails the waiting write (late failure, as a Save's); and a `(deleted)` cwd is no name to take.

| | | | | | | | | | | | | shell never started ends exit 127 Exec made a command pane in a directory that was not there, whose shell never started: it said running for ever, a follower waited for an exit that never came, and Kill found it. The line now fails up front, as Tty does, `exec: <dir>: no such directory`; and a command pane whose shell the host could not start ends `exit 127` at once. A shell that could not start in its directory says `directory missing`, not `file not found`. Co-Authored-By: Claude Opus 5.5 <[email protected]>

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.

* A terminal is typed into only when idle at an empty promptGabriel Schneider6 days
| | | | | | | | | A look at a directory, or an exec at a terminal, typed its line after whatever sat unsent at the prompt and ran the two joined (`echo TYPEDls`). A terminal with text at its prompt now takes no line; a look at its directory opens a new terminal, an exec runs as a command pane. Co-Authored-By: Claude Opus 5.5 <[email protected]>

| | | | | | | | | | | | miss fails Round 18 made a search that found nothing fail, but grep and find never counted their rows (only a pane search did), so every Grep read as a miss. Both count the lines they wrote now; a Find or Grep that finds nothing fails alike, `find: no match, not found` / `grep: ...`, ENOENT, and opens no empty +Search.

* A new terminal is named by its directory from the start, so its shell ↵Gabriel Schneider6 days
| | | | | | | | | | arriving there is no rename Tty's terminal was `new N /` until its shell reported its directory, then `rename N <dir>`: a rename for no change of place. The pane owns the directory it is started in from the first; only a move elsewhere renames. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A builtin failure over something not there answers ENOENT: Unmount of a name ↵Gabriel Schneider6 days
| | | | | | | | | | not mounted `Unmount nothere` failed EIO with `not mounted`. It says `no such mount nothere` now, and a builtin's failure that says `no such` (this, Tty's `no such directory`) answers ENOENT, the errno 9ns reads from those words. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Grep with no hit says grep: no match, and a pane directory that is not there ↵Gabriel Schneider6 days
| | | | | | | | | | | is passed over Grep walks every pane's directory; one not there (a scratch named into a directory not made yet) failed the whole search with `file not found`. Such a root is passed over now, and a search that finds nothing says `grep: no match` and opens no empty +Search. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A builtin that needs its argument, written bare to an exec, is EINVAL as ↵Gabriel Schneider6 days
| | | | | | | | | | through ctl Through a ctl the bare word was refused up front (EINVAL); through exec it ran, failed with EIO or asked for the argument. The exec now refuses it the same way before it runs. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A new terminal's greeting `ls` goes at its shell's first prompt or neverGabriel Schneider6 days
| | | | | | | | | | | The greeting waited for any moment the cursor sat at a prompt's input, so where the first prompt was missed (a resize still pending, a line written before it), `ls` was typed later into whatever ran then. It is now sent only while nothing has run (pardes's marks saw no command start) and nothing is typed at the prompt; past that it is dropped, never typed late. A prompt drawn again for a resize is still the first. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* get on a pane of a peer out of reach says dial failed, as look and Save doGabriel Schneider6 days

* The docs: the root exec's lines are the active pane's in the log, a tag's ↵Gabriel Schneider6 days
| | | | | | | | | | are `-` fs.md said a root exec logged `-` while the keyboard was on a tag; it runs at the active pane and logs that pane's serial all the same. The `-` is for /tagexec, a column's exec and ctl, and the root's ctl. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A column ctl write reads back what it touched aloneGabriel Schneider6 days
| | | | | | | writeCtl never cleared what the last write touched before its lines ran, so `New` through col/<n>/ctl read back the earlier write's serial too. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A name write is one name, refused with its reason otherwise; a log record is ↵Gabriel Schneider6 days
| | | | | | | | | | | | | one line of UTF-8 A name took a second line, DEL, a C1 control or bytes that are not UTF-8, which then went into /index and /log as they were and split or garbled a reader's lines. `name` strips one trailing newline and refuses the rest, saying which (`bad character in file name: not UTF-8`); and the log turns DEL and C1 into spaces, as it did control characters, and escapes bytes that are not UTF-8 as `\xNN`. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A rename alone does not make a pane dirtyGabriel Schneider6 days
| | | | | | | | | Any rename marked the pane dirty (saved revision one back), while the guards ask only whether its text was ever edited: /index said dirty for a pane Exit let go without asking. The name is no edit now, so /index, the guards and Restore agree; Save writes under the new name all the same. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* The root exec's refusals before a line runs name the pane, and say invalid, ↵Gabriel Schneider6 days
| | | | | | | | | | | so a mount reads EINVAL A line over 1024 bytes or with a control character was refused with its errno EINVAL but words 9ns reads as EIO (no `invalid` in them), and logged `err - exec`. They now say `invalid command line: ...`, and the root's err record names the pane the line would have run at. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* `@p<terminal>:N` past the terminal's last line is a miss, as in a fileGabriel Schneider6 days
| | | | | | | | The line-past-end check read only a file pane's lines, so a terminal's look went nowhere and said nothing. A terminal's lines are its logical lines, as a +Search of it lists them. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Tty in a missing directory fails and makes no pane; a shell that never ↵Gabriel Schneider6 days
| | | | | | | | | | | | | started answers runs 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: <dir>: 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`. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A Save whose write fails changes nothing: not the name, not the dirty flagGabriel Schneider6 days
| | | | | | | | | A scratch took its new name before the host wrote it, so `Save /root/x.txt` failing with EACCES renamed it anyway; a failed write to another name marked a clean file dirty. A scratch is now named once its write is done (promoteSaved), and a failed write puts the saved revision back. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A Save refused for want of a name counts as a failure, so its announcement goesGabriel Schneider6 days
| | | | | | | | A builtin that would open a prompt nobody can answer (Save with no name on a scratch, through a ctl write) failed the write without saying a failure, so the announcement rule missed it and `msg N Save` stayed. Co-Authored-By: Claude Opus 5.5 <[email protected]>

| * G10: the theme's chrome fades through OKLab, easing in and outGabriel Schneider6 days
| | | | | | | | | | | | | | | | | | | | | | | | ChromeTheme.interpolate mixes each colour in OKLab (colors.mixOklab), so a fade between hues keeps its lightness instead of going dark and muddy mid way; animation.Fade eases it in and out (smooth), and one retargeted mid fade eases out from where it shows, so it never stalls. Still 10 frames (160 ms). The page, text and syntax colours change at once as before. Tests: OKLab round-trips its ends exactly and keeps a red-to-green mid-way brighter than the sRGB mix. Gates as G9 (no golden moved). Feel review: .scratch/render/crossfade/.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | SelectionGlow on|off (off; a pixel shell's, Chrome.selection_glow): each block of selected rows in a pane body casts Lift's soft kind in the selection's own colour, the block its caster (never touched) and a cursor beside it joined to the caster; clipped to the bodies (never a tag or a grip); at most 22% (§8.2), less where the text round it would drop below min(its contrast, 4.5); fading in over 100 ms with an ease-out, on the core's continuous path (shell_continuous); none while panes move. Blocks come from the cells in the theme's selection colour (documented). Tests: the halo's colour, its clip to the body, nothing at its first frame and up to its cap after 100 ms, fading done. Gates as G8. Feel review: .scratch/render/selection/.
| * G8: a notice leaves quicker than it arrivesGabriel Schneider6 days
| | | | | | | | | | | | | | | | | | | | | | | | | | The notice chip's motion was mostly there (a drop easing out on the Motion flavour, a dissolve easing in, Lift's shadow in tier 4 at its fade). Its dissolve took 300 ms against a 180 ms fall, the wrong way round for §8.1 (leaving quicker than arriving, 100 to 160 ms): MessageDissolve now defaults to 150. The field comments had the two easings swapped; the stack test pins a longer dissolve for the case it checks. docs/config.md and docs/effects.md say so. Tests: both timings in their bands, leaving quicker. Gates as G7 (no golden moved). Feel review: .scratch/render/notices/.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dissolve crossfades - 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/.
| * G6: a wheel's notch scrolls the core at once and the picture glides after itGabriel Schneider6 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A mouse wheel's notch (SDL's whole-number step, notchOf) scrolls the core by its lines at once, so keys and clicks act where the text is, and the picture follows on the Motion flavour's spring at half again its pace, critically damped whatever the flavour (text never passes its mark), carried from its current speed (animation.Spring.carry), so notches in a row flow on. How far the rows moved is measured on the next frame against the last (Glide.measure: a wrapped line's rows, a terminal's output, with a couple of rows' slack for the cursor's line and its number); the rows that left are kept, nearest first, and drawn in the gap the lag opens; the lag is never more than the body's height. A touchpad's fractions move the picture under the finger as before; `Motion off` lands a notch at once; a PDF page scrolls as before. The glide runs on the core's continuous path: Pardes.shell_continuous keeps frames coming every loop while it moves and carries a virtual clock with it; idle, nothing. The test feed takes wheel events (ESC]777;mouse;wheel;<amount>;<x>;<y>BEL). Tests: notch vs fraction; a carried spring keeps its speed and never passes its mark; a notch over two-row lines lags two rows, keeps the rows that left, settles frame by frame and leaves the continuous path, and lands at once with Motion off. Gates as G5. Feel review: .scratch/render/scroll/glide-{smooth,crisp,bouncy,off}{,-quarter}.mp4 and strips (a notch down, three, then two up).
