to find it
setEditText found the last edit's end by comparing the old and new texts from both ends and counting rows to it, twice over the file on every keystroke: edit-char grew with the file (+135% at 300k lines). Typing, deleting, Enter and Tab now pass the end they know (setEditTextEnd); the comparison stays for the edits that do not say (paste, pipes, s). perf edit-char: 50k lines 16661 -> 15286 us, 300k lines 30507 -> 22291 us (render alone ~13.6 ms of each, the render agent's).

let the GUI rest; a perf gate
somtrmsz's contrast floors made ChromeTheme.fromTheme run its focus-tint
and separator searches (pow calls each), and Output's RowDecoration.styleAt
called it for every grapheme of every highlighted row: the 50k-line file's
render went from 0.11 ms to 13 ms. Pardes.bodyChrome now keeps the theme's
chrome, worked out again only when the theme differs; recolorSyntax asks
for it once a decorated row, and a plain row (nearly every row of a file)
never asks. ReleaseFast, medium fixture, median us, before -> after (main):
render 13150 -> 76 (111), key-down 14658 -> 79 (110), wheel 13589 -> 76
(109), open 14891 -> 2095 (2055), edit-char 16703 -> 3006 (1251; the rest of
that gap is editing and tree-sitter, not this).
Post.animating asked for frames whenever the window had focus and any pass
was ready, so a still pass kept the GUI drawing at the display's rate
(Bloom: 49% of a core idle, in a hidden test window). A pass now says
whether it moves on its own: the CRT (its hum and dither) and a Shadertoy
file whose source reads iTime, iFrame or iDate (shader_build.readsTime; the
flag rides the wire's post message); Bloom, Vignette and Grain are still.
Bloom idle: 49% -> 1.2%, as with no pass.
zig build perf-gate: the 50k-line file's gestures, each's fastest sample
within 3x of the recorded baseline's (test/perf-baseline-<platform>-
<optimize>.json, recorded from this build), run with every unit-test. On
the regressed code it fails at 180x for render.

came from
Once the workspace tag was edited, its own text kept the Restore <path> of the dump at that time, stale after the next Dump; and a Restore dropped the path altogether (the new session had no last dump). A new dump now swaps the old path in the tag's own text, and a Restore points the word at the dump it read.

room fails, and so does a write to an image's or PDF's body
Callers or Callees with nothing found, Hover or Lspwhy with no room for its pane, and a question asked of no file's pane said nothing, the 9P write succeeding; a body write to an image or PDF pane went nowhere. A write that asks a language server now waits for its answer (turn.lsp_answers), and what fails there -- nothing found, no answer, a backend's @none why, a placement with no room (ENOSPC) -- fails the write and logs its err. No diagnostics is said, not failed.

A Restore makes a new session, which never loaded the kept list, and saveRecent gives up until it has: Recent was empty after a Restore and nothing opened afterwards was kept. The new session now takes the old one's list (a boot from a dump reads the kept file).

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).

The rename turned `MissingThemeSelection` into `MissingThemesection`; the

as legacy, a section per ported family
The picker's headings come from colors.theme_groups instead of one split at
native_theme_count, so acme (current, matched to plan9port acme's source)
no longer sits under a legacy heading. Ring order follows the sections:
the fifteen pardes palettes, acme, lapis, the faithful ports a family at a
time, then helix and dark, then the imports. An imported theme whose name a
port takes gets _helix, as zed's carry _zed.

the new one
G3's springs now keep the cursor's place in its pane: a pane that moves in
the layout carries them, and the quad is drawn through the pane's presented
box (its transition track), so through a slide, zoom or drag the cursor
rides with the text, and with no transition it lands with it. A focus change,
to another pane or into a column's or the workspace's tag, glides from where
the cursor was drawn to the new place instead of snapping, unclamped while it
crosses. While panes move the cursor is drawn as the overlay quad instead of
vanishing (golden 18-mid-transition re-recorded for that: the only change is
the quad, gliding into the new column's tag).
Lapis: a tag plaque starts flush against its grip's button, the scroll gap
between them part of the plaque, so grip and plaque read as one piece, on
pane and column rows alike; below the button's row the grip keeps its band.
Themes without plaques are unchanged (their grip band and tag band are one
colour, no sliver).

test/gui_golden.py hashed a scene once two captures 400 ms apart agreed;
on a loaded machine a slow frame agreed with itself before the scene's
change landed and every later hash moved up a scene. A test window now
writes a status file into its capture directory each loop step (gui.zig
writeTestStatus: step, frames captured, idle — nothing owes a frame,
nothing moves, nothing waits on the core's clock), and the harness waits
for an idle step two past the one current when it asks: a 9P write has
been served by then, so the frame is the scene's. Two things kept a
window from ever going idle, both fixed:
- Look-hover re-armed forever: resting on a word with nothing to open, the
hover wait ran its two frames, found nothing, cancelled, and the next
present's pointer refresh started it again: a frame every other frame
for as long as the pointer rested there, live too (CPU). The place last
refused is remembered (Pardes.look_hover_refused) until the pointer
moves off it.
- The virtual clock moved only on a wait that timed out, so a steady
trickle of events held it still; it now moves to the core's wake too
when an event cut the wait short and nothing owes a frame.
Captures go to a directory of their own, outside the session's (a file
written there every frame is a change in the directory its panes look
at). All 17 goldens match the file as recorded at oooopqyv; eight runs,
five alongside a ReleaseFast build and three with all 16 cores saturated
(load 13-19), were byte-identical, 14 s a run unloaded (was ~30).
Tests: the resting pointer lets the core go idle.

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.

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.

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.

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

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.

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.

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.

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.

spoken, so it logs no rename to the session's and back
Each host read /proc/<pid>/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.

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.

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.

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.

A native theme `lapis` (src/themes/lapis.zig) from web/theme/lapis.css:
a lapis-deep page, lapis tags with gold names, vellum text, vermilion
rubrics, gold rules and a vermilion tag rule, gold selection in lapis ink.
Its ornament is the theme's new `decor` (colors.Decor), drawn by a pixel
shell inside the chrome it already has (decision 1), all of it off every
focus indicator:
- page_dots: the site's gold dot grid (#e8c46a22, 22 px), drawn by the
cell shader on page-coloured cells alone (flag 0x10000000), so it lies
under the text and never under a selection, a tag or the cursor; fixed
to the window, a page the panes lie on.
- rail_checker: the dither frame's gold and lapis checker in the scroll
track (a decor kind, flag 0x08000000), anchored to its rail; the thumb
stays solid gold.
- tag plaques (tag_border, tag_shadow, tag_stripe): every tag a raised
plaque inside its own band, the site's trail: a 2px gold frame and a
hard 5px vermilion shadow down and right, both within the band's rows
and columns (down, what the slack under the text leaves), so no shadow
reaches a body, a grip or the next pane. The focused pane's plaque is
the code window's title bar, gold and lapis stripes of 2px, its words
on plates of the focused ground; unfocused ones are plain; column and
workspace tags take the object-label language (1px frame, 2px shadow
toward the page). Drawn as decor under the cells (a group's under
range), with blank tag cells see-through and the cells blended
premultiplied (pipeline_over) on such frames; opaque windows only.
- title_shadow: the titles' vermilion offset shadow under a file name's
letters, sampled in the cell shader inside the letters' own cells (flag
0x08000000), none on a cursor.
Chrome carries the decor (decor_*, name_ink, active_name_ink); a theme
file folds a nested decor literal field by field. Left out, with why, in
docs/effects.md: the fonts, the ornaments, a decor crossfade, and in the
tty anything but the colours (a tag row has no spare cell for a shadow).
An empty column is the page. The effect id is masked to 27 bits (ui.vert/ui.frag) for the
fifth flag.
Tests: the cell flags land only on page ground and file-name cells, never
a cursor, nothing without decor; lapis's plaques stay inside their tag's
band, clear of every grip, only the focused one striped; its checker is in
the track; no other theme draws any; the separator and focus
tests cover lapis. Goldens: theme and themesel (the ring gains lapis after
acme). Gates as G4. Feel review: .scratch/render/lapis/ (lapis.png, lapis-2x.png,
tags-focused-vs-unfocused-2x.png, a PanelSlide at 60 fps and a quarter).

separators and focus tints
Density: dp() in gui.zig draws every size given in pixels in logical
pixels (SDL's window display scale, rounded, at least one), as acme scales
Border, ButtonBorder and Scrollgap: the rules (rule_px), the tag rule, the
grip's ring, its dirty gap and mode bars, the rail's gap to the text and
its minimum, the thumb's inset, the rim, a bar cursor's minimum width,
underline and strikethrough thickness (the atlas is dropped on a scale
change), the rule-grab margin, and the Crt's scanline and mask periods
(pardesScale in the post prefix). Cell- and tagline-measured sizes stay:
the rail's width, Lift's blur and offsets, every motion; iResolution,
fragCoord and iMouse stay in the display's pixels, as ghostty's.
PARDES_TEST_SCALE forces a density in a harness (a test window is 1x
otherwise, whatever display it lands on) and sizes the test font with it.
Colours: a separator that stands off its page by less than 1.5:1 is lifted
toward the text to 1.6:1 (helix, atelier, paper; a theme with no page,
dark, is judged against #121212), and empty_col follows it. forge's own
rule already stands at 3.83:1; what hid it was density: 2 device pixels
on a 3x screen, now 6 (dp). A focused tag's tint closer than 1.5:1 to the
plain tag on a dark page (1.25:1 on a light one) is pushed further the way
it leans, as far as its text keeps its own contrast or 4.5: forge
1.23 -> 1.51 (#2d3440 -> #374253), and likewise dusk, orchard, ink,
lagoon, clay, harvest, spectrum, solarium, forge_soft; daybreak, atelier,
paper to 1.25. dark and helix gain a tint of their own (dark: #484566
under #c8c8c8, 1.54:1; helix: ramp 237 under 250, 1.65:1).
Tag caret: past a full row's end, the G3 glide box sits on the tag's right
edge, where the layer's caret and the pixel shell's are.
Tests: every native theme's separator >= 1.5 and every dark one has a
tint >= 1.25 with readable text; forge keeps its own border; the tag caret
glide box at a full row; at 2x the spine, tag rule, ring, rail start and
gap, and bar cursor double. Legacy-ThemeFile test strips helix's new pair.
Goldens: snapshot goldens change in colour rows only, the tints (orchard
#283a2f -> #314738 at boot, forge, helix and dark in theme/themesel).
GUI goldens: the harness's single Del of the renamed wide pane is refused
since ysqnkyoy (a rename counted as unsaved; fixed on the 9P line in
wkzlsqvy), so scenes 09-17 were recorded with that pane open and the file
was stale since the merge (08 and 18 also moved with ykvnltvs's full-row
tag wrap). The goldens here were recorded with that pane closed (as
wkzlsqvy will close it); against the parent's binary under the same
conditions they differ only in the tints: 01-13 forge's (#2d3440 ->
#374253, and the glyph edges on it), 14 ink's; 15-18 are byte-identical.
Until wkzlsqvy is merged, a run here fails 09-17. Each commit reproduces its own
recorded goldens on this machine (checked at kvtmqkyn). A test window is
1x unless PARDES_TEST_SCALE says otherwise, whatever display it opens on.
Prebuilt shaders refreshed from their sources.

is said as `dial failed: <reason>`
Mount took any well-formed dial and nothing was found out until the
first look through it, which then said `look: look: dial`. Mount now
probes the peer (version, attach, its root) with the turn out, and fails
its write, mounting nothing, when none answers; the dial errors read as
words, `no answer`, `timed out`, `hung up`, and a look through a peer
gone since names its path: `look: /n/peer/f: dial failed: no answer`.

Every look that found something cleared the looker's selection first, so
`@p5:2` or `f.txt:2` written to a pane's look collapsed its dot to
q1-1. Only a look that stays in the pane starts from a clean selection
now; one that goes elsewhere takes away just the click's highlight, and a
miss changes nothing, as acme's look does.

smaller window
A terminal of one body row loses its prompt's mark and reads busy for
ever. Placement already refused to make one that short; now layout never
leaves one there either: a grip drag stops at the floor, and a column
squeezed by weights or by the window takes the rows from its other panes.
Text panes keep acme's way and can still be dragged to their tag, since
acme has no terminals to follow. The shrinktag, splitparent and cornerdrag
goldens are re-recorded for it, shrinktag's re-grab moved to where the
grip now is.

busy for ever
A one-row pty loses the prompt's input mark as soon as the prompt wraps,
and busy detection never sees the shell idle again. Placement already
keeps a new terminal at tag + 2 rows; a winsize write now keeps the pty
at two. A pane dragged down to one body row keeps a one-row pty, since
a taller pty than the pane shows would put its cursor below the pane.

A builtin that failed through a ctl failed the write and logged its err,
but through look, exec, tagexec or a column's exec it only said so on the
message row, logged as a msg, and the write succeeded. Now every click
write runs its builtin as a ctl line does (ctl.captured): a failure fails
the write, with its words (EINVAL for malformed input, else EIO or what
the words name), logs one err and no msg or announcement. get's Modified
and a look miss are shown but logged once, as their err. A control
character's refusal names its reason, a failed click reads back nothing,
and look never reads back a pane closed since. The special case for a
cut-short Edit through exec goes (the rule covers it); fs.md's table of
exceptions becomes the one rule, as does the skill.

a line-number look said @p<slot>, the pane's place in the core's table,
which no client can see. They now say @p<serial>, and @p resolves a
serial. Re-recorded by name, their diffs checked: jumps, ttylook and
psearch (whose waits now say @p1) for @p<serial>, and with them argv,
nested, reflow, tinywin, ttyhelp and ttyonly for the boot scratch now
named <cwd>/+New (the change before).

Repl showed Joincol's first line and Joincol another's, because a comment
had drifted above the wrong declaration in builtins.zig; Kill's was cut
mid-sentence and Exit's cited exec.c:892. The drifted line is back on
Joincol, a parenthesis citing source (.c, .zig) is dropped, and the first
sentence is kept whole up to 240 bytes, then cut between words with an
ellipsis. A test checks every description opens its own word's comment.

A /commands line gave a word, its argument and root or pane, but not
what it does, and called Edit a pane's word though the root's ctl takes
it too. Each line now ends with -- and the first sentence of the word's
doc comment (read from builtins.zig itself, so there is one copy), and
Edit is both. fs.md says a pane's word such as Undo or Msg is refused at
the root.

A plain word looked at (a look write, a right click, an ML record written
back) opened another identically named +Search pane each time, until the
panes ran out, and never wrapped. As acme's look3 searches the text for
it (look.c:210), it now selects the word's next place in that pane after
the dot, wrapping at the end, and opens nothing. LookWord list, a new
root setting, keeps the +Search listing (search is the default); the
rsearch snapshot and an output test that walk the listing say LookWord
list. (The leader-path check over every builtin gets a comptime
branch quota, as one more builtin took the GUI build past the default.)

A watched file rewritten on disk was loaded over a buffer's unsaved edits
and its dirty flag cleared, so Exit and Del no longer asked about them. A
clean buffer still reloads; one with edits keeps its text and stays dirty,
says <file> changed on disk (get reloads it, Save overwrites it), logs
changed <serial>, and its Save warns once before overwriting the newer
file, as acme's Put refuses a file modified since read (exec.c:577); get
asks as ever (winclean, exec.c:513). The restored-watch test's dirty case
now keeps the snapshot, and the filewatch snapshot script (re-recorded
by name) checks both halves: the edited pane keeps its edit and says so,
the clean one reloads.

The Enter went on Python's first output after the paste, before it had
taken in the whole paste, and one Enter leaves a multi-line input at
... anyway. Python's output now only restarts a 100 ms quiet wait (the
250 ms fallback stays), and a paste of more than one line gets the second
Enter a block gets. fs.py runs print(11)\nprint(22), the same with a
trailing newline, and a for block followed by a statement in a real
python3, each back at >>>.

busy said only that something ran. Where the host can tell (Linux, the
tty's foreground group's /proc comm, a new fg_name host call), it says
busy: <program> is running; elsewhere, busy as before. The GUI's host
gains the one small callback (render agent's file: gui.zig, fgName).

size refused an out-of-range line without saying the range, took a size
too small for the panes (leaving bodies of no rows), and a terminal
squeezed to its tag kept a pty of its old size. The refusal now names
20x6 to 4096x4096 (a bare size is EINVAL like any malformed line), a size
that would leave any pane less than its tag and 2 rows is refused and
undone, and a terminal's pty is resized with its pane down to one row
(only a folded or unplaced one keeps its grid).

A directory passes access(X_OK), so Tty /etc made a pane whose shell
exited 127 and Shell /etc was taken. The shell lookup now refuses a
directory, and both say "not a shell: /etc is a directory" (Tty and
Shell share one refusal, host_io.Shell.refusal). shellset's golden takes
the shared wording (re-recorded by name).

sendToRepl timed the Enter's fallback from stepped_ns, which in an idle
detached session is as old as the last frame: the wait was over before it
began and the \r went out with the paste, which 3.13's REPL then reads as
part of it (4 of 5 sends lost their Enter). The wait now starts from the
host's clock and is checked against now_ns; the REPL's echo of the paste
still sends it sooner, and the wake is scheduled for the deadline. fs.py
sends five times after two idle seconds each in a real pty.

A --detach session nobody is attached to stayed 80x24, too small for an
agent's panes, and nothing could change it. The root ctl takes size <cols>
<rows> while no frontend is attached (refused while one owns the size), and
a client that attaches later still sets its own (the server compares with
the core's size). Documented with the 80x24 default.

Shell took any word and the host quietly ran another shell at the next
spawn. It now refuses a path or name that is not executable ("Shell: x:
no executable by that name", failing a ctl write, logged err), a bare
Shell goes back to the default, and a default $SHELL that is not
executable falls back to /bin/sh. shellset's golden takes the refusal on
the message row (re-recorded by name).

Placement could split a pane down to a tag and one row, or give a new one
less. Every placement now checks the pane it made and each pane it shrank
against its tag (wrapped at its width) plus two rows: where they lack the
room, the column's tallest pane is halved instead, and where none can give
it the new pane is refused with "no space for a pane in that column"
(ENOSPC over 9P) and closed at the step's end, once its maker is done with
it. splitBelow and splitParent leave two body rows (a boot layout, split
before any row exists, is as before). Re-recorded by name: lookpanes (panes
one or two rows lower) and splitparent (the 6-row squeeze now refuses);
fs.py closes the scratches and long-named panes it no longer needs, since
its 24-row session filled.

With no Shell set, pardes ran fish, which a box may not have and a user
may not use. The default is now the user's login shell ($SHELL), else
/bin/sh; an explicit Shell still overrides it. The tests pin their own
shell (snapshots bash, the python suites /bin/sh or bash) and pass with
SHELL unset; the Config report and docs say where the default comes from.

A mount cuts a write at its message size, and each piece ran on its own: a
line cut at the boundary ran as shell commands and a 50 KB Edit block
broke. An open of look, exec, tagexec, any ctl or a column's exec now keeps
an unfinished last line, or an Edit block still open, until its next write
or its release, and never runs a fragment. The same open record holds what
its last write touched, which a read on it answers (as /net/tcp/clone
does); an open that never wrote reads the session's last as of its open.
A release that runs a held line waits for quiet and counts as a change;
a clicked line with a control character is still refused at its write.
Tested in unit tests, fs.py (python client, 8 KiB) and selfmount.py (the
kernel mount, a 1000-line seq burst and a 50 KB Edit block).

and a tag's words log as the session's
/tagexec runs a word as a click in the workspace tag, as col/<serial>/exec
does in a column's. A column's exec was write-only; it and /tagexec now
read back the serials the last write touched, as /exec does. A click in a
tag no longer goes to the focused pane's event reader, and what a word
run from a column's ctl or exec or /tagexec says is logged msg -, not
against the focused pane. The README, fs.md and the skill say so, and
document the answer record.

After a Restore the dot came back on the match it was on, but N stayed on
that match instead of wrapping to the last as it does live: the walk
remembers the spot it landed on (look_at), and a restored pane has none,
so it stood at the cursor, the selection's end, and found the match it was
in. A one-row selection now counts as where the walk stands, from its
start and past it either way, as a landed spot does.
