The curtain's glyph slide becomes a wipe: the new grid behind a head that
crosses the pane, the old ahead, and between them two columns whose colours
step from the old ground to the new in OKLab (CharSource.edge). Only the
head's columns change from frame to frame.

ThumbFlash (off by default) brightens a body's scroll thumb toward the ink
when its view moves and fades it back over 250 ms, truecolor only. The tty
present path now clears shell_continuous once before its effects and each
effect only raises it, so the trail and the flash no longer mask each other.

ChipShadow on|off (off; the tty shell's, §9.2 T1): each notice chip casts
a shadow one cell right and one down inside its own pane's body: on a
blank cell a half block (▌ right, ▀ below, ▘ at the corner) in a colour
35% darker than the ground (OKLab), so the shadow is half a cell thick;
under text the ground itself darkened. Never the cursor's cell, a
selection, a tag or another chip; truecolor terminals only.
Tests: the shadow lies right of or below the chip, never in it; nothing
with it off or without truecolor. Snapshots unchanged. Feel review:
.scratch/render/tty/shadow/.

animation.dissolveRevealed (the tty compositor's dissolve and the pointer
mapping that follows it) swaps each changed cell once at its place in a
4x4 Bayer matrix, shifted by the pane's serial so two panes differ,
instead of at a hashed noise threshold: the new content comes in as an
even patterned screen (§9.2 T4). Endpoints stay exact.
Tests: a 4x4 block reveals exactly t x 16 cells at t = 1/4, 1/2, 3/4.
Snapshots unchanged. Feel review: .scratch/render/tty/dissolve/ (the
matrix over two real frames; the recorded session's pane did not
animate, noted in docs/effects.md).

JumpTrail on|off (off; the tty shell's, §9.2 T2): a jump of three cells or
more leaves three to five cells of trail behind the cursor along its path,
their ground mixed toward the text's colour in OKLab (most beside the
cursor), fading out over 120 ms. Truecolor terminals only (vaxis's answer,
or COLORTERM truecolor/24bit); never the cursor's own cell, a selection or
anything outside the focused pane's body; none under Motion off. It rides
the continuous path (Pardes.shell_continuous) while it lasts; a few cells
of output a frame. docs/effects.md opens the terminal track with the audit
under decision 2 (keep and polish, remove nothing).
Tests: a ten-cell jump lights 3 to 5 cells behind the cursor on its row,
gone by 120 ms; a one-cell step and a terminal without truecolor light
none. Feel review: .scratch/render/tty/trail/ (a real tty session replayed
through pyte at 60 fps).

Afterglow on|off (off, a pixel shell's; Chrome.fx bit 4): the GUI keeps
the grid it last drew and when each cell changed; a body cell whose text
changed glows in the theme's accent, at most 18% and under the text's
contrast floor, fading with an ease-out over 250 ms, one flat rectangle a
run of cells that changed together; never a tag or a grip, the cursor or a
selection; a scrolled body (its first line moved) starts over rather than
lighting up whole. On the continuous path while anything glows.
Tests: three changed cells glow as a run of two (the cursor's left out),
gone by 250 ms, a scroll lights nothing. Gates as before; goldens
byte-identical. Feel review: .scratch/render/afterglow/.

Parallax on|off (off, a pixel shell's; Chrome.fx bit 3). A body region
carries its first line (Region.line, a file's scroll or a terminal's grid
offset; the wire's region record grows a u32). The GUI offsets each
body's page dots by a quarter of its line in rows, and of G6's glide
offset while one runs, so the pattern drifts with the text and settles
with it; the cell shader reads it from the instance's serial slot, whose
per-cell dissolve noise G7 left unused (the dead noise code goes).
Tests: a scrolled body tells its line; the shift handed to the shader is
a quarter of it within the dots' period. Measured in a capture: four lines
move the dots 13 px (140 px / 4 mod 22). Gates as before, goldens
byte-identical. Feel review: .scratch/render/parallax/.

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.

Occlusion on|off (off, a pixel shell's; Chrome.fx bit 2 — the glow bits
field is now `fx`): four soft strips cast from just outside each pane body
inward, clipped to the body and round a cursor, black pre-warped to
linear light, 2% at most (§9.1) and under the lift's contrast ceiling,
in the pane's own group.
Tests: the shade stays inside the body, off the cursor, at most 2%.
Gates as G11. Feel review: .scratch/render/occlusion/ (with an x40 diff).

HoverGlow on|off (off, a pixel shell's; Chrome.glows bit 1, SelectionGlow
bit 0 now that there are two): under the word a look-hover would open (its
cells in the affordance's tint) a strip three logical pixels tall along
its foot, blurred by one, in the theme's accent, at most 22% and under
the text's contrast floor, fading in over 80 ms; kept to the bodies and
split round a cursor. glowBlocks serves G9 and G11. The strip is cast from
a row away so addSoft's caster cut-out misses it.
Tests: the glow comes up by 90 ms and never falls on the cursor's cell.
Gates as G10 (a loaded machine shifted the GUI goldens a scene once; a
rerun matched 01-08). Feel review: .scratch/render/hover/.

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.

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.

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.

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

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

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.

newline
With `\n` for a newline and `\xNN` for a bad byte, a name holding a
backslash and an n read back as one holding a newline. Names in /index,
the log and a terminal's tag now double their own backslashes; and a
terminal's directory with a newline no longer breaks its tag.

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.

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.

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 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 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.

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`.

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`.

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.

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.

exit, the tag's default words, empty matches at #0, errors' fallback, tagexec and event readers, Find finds names
Dogfood round 18 found these false: `>>` on data replaces the addressed
range (acme's data write deletes then inserts); a restored command pane
shows the `exit N` it ended with; the default tag words are `Save Tty
Collapse Del`; `file:0/^/` passes over the empty match at #0; `errors`
with no room logs msg records; a pane's tagexec never goes to an event
reader; a scratch is named with `(pane N)` in a refusal; and /commands
said Find searched the pane, where it finds file names.

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.

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`.

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.

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.

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.

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`.

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 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.
