callers not found
The ENOENT that 9ns reads from a failure's words came from a tacked-on suffix, grep: no match, not found, definition: nothing found, not found, no shell "x", not found. They now say it once: grep: pattern not found, find: name not found, Callers: callers not found, definition: not found, shell "x" not found (...).

A file deleted under an open buffer left dirty 0 and let Del, Exit and the rest throw the only copy of its text away unasked. It now counts as dirty, as acme's does, and the refusals ask about it.

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.

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.

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.

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`.

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.
Captures: .scratch/render/dark-borders/{before,after,compare,scale2,scale3}.

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.

A +Search row for a pane with no path (a terminal's), a jump list row and
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).

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.

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).

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 script could read and write a column's tag but not act on the column.
col/<serial>/ctl takes Delcol, Joincol, New and Tty, each acting on that
column as from its tag; col/<serial>/exec runs a word as a middle click in
the tag; rmdir col/<serial> closes an empty column and refuses one with
panes (ENOTEMPTY, an err record saying why). The root ctl's refusal of
Delcol and Joincol points at col/<serial>/ctl. A dump keeps each column's
serial and Restore logs restoredcol <old> <new>; the dump golden gains
them. Documented: Joincol's survivor, the column on the right, keeps its
serial and tag.

A press on a pane's last row began a seam drag, so the row could not be
clicked or swept like the rest of the text (rsearch dragged the handle out
of the way first). Now no row of text is a handle: in the GUI a press on
the 2 px rule between two panes drags their seam, and anywhere the grip
does, as acme's button moves a window -- dragged up or down its own column
it moves the pane's top, either pane down to its tag alone (acme's
coldragwin), dragged down inside itself too. The hover hint over a last row
is gone; column edges resize as they did. Scripts that dragged a seam drag
a grip instead and match their goldens; six goldens lost the hint or moved a
cursor to the clicked text, re-recorded by name.

A session running with Placement pardes came back from Restore as acme: a
dump kept the layout and the theme but no setting. It now keeps every
setting line that differs from a fresh session's, as the root ctl reads it,
and a Restore applies them; the theme stays where it was kept, the font the frontend's,
and REPL bindings are still dropped. The dump golden gains the three the
snapshot harness sets.

Tags wrapped one cell early to keep a cell for the caret past a full row,
so a tag that exactly filled its column broke as De / l. acme's frame wraps
a box only when it is wider than what the row has left, and frptofchar
clamps the tick past a full line's end to the frame's edge. Tags now wrap
at their full width; the caret past a full row sits at the tag layer's
edge, and on the pane's last cell in a terminal grid, which has none past
it. Two tiny-screen tests collapse their tags, as the others do, and the 41
goldens that moved were re-recorded by name after the same check: rows
shift back up under the shorter tags and nothing else changes. chordcut's
file-body clicks moved back with them.

rules
acme takes plan9port's own colours (acme.c iconinit, draw.h): selections
#eeee9e in the body and #9eeeee in the tag, black ink; exec and look sweeps
#aa0000 and #006600, white ink; a #99994c scrollbar under a #ffffea thumb;
black rules; a #8888cc tag/body rule and column button.
Every theme: the grip is acme's button, its tag row's full height, in one
scroll column with the scrollbar (rail_px, 12 at a 17px tagline, scaled,
times GripWidth, a percent, default 150; same x0/x1 to the pixel):
focused clean = solid box; focused dirty = box_dirty filled to a box ring
(acme's modbutton); unfocused clean = a box_border ring round the tag's
ground; unfocused dirty = box_dirty a pixel inside that ring. The grid, which
has no ring, marks dirty with a bold * on box_dirty in the grip's second cell
and fills an unfocused grip halfway to its ring. Regions carry a dirty flag.
Column buttons are the same shape, solid. 2px rules between columns and
stacked panes (inside the tag band's slack), none at the window edge; a 1px
tag/body rule halfway between tag and page.
Theme data: tag_sel_bg, sweep_bg/fg, tag_rule, rule_px, rail_px, box_border,
box_dirty. Chrome: rule_px, tag_rule, rail_px, grip_border, grip_focus_ring;
a comptime guard on Chrome's layout forces a wire bump once v8 ships.
Structural rules are exempt from the focus-indicator rule (docs/effects.md).
Tests: acme widths; stacked rule in the slack at two tagline sizes; every
grip-column pixel is band, button, ring or rule, and the button shares the
scrollbar's x0/x1 (4 metrics x top/bottom x focus x dirty); the four grip
states distinct in every native theme with a non-colour dirty cue in the
grid; wire round-trip of the new fields.
Shared files: src/colors.zig, src/surface.zig, src/body_layer.zig,
src/tagline.zig, src/detached/wire.zig, docs/themes.md, docs/config.md,
docs/effects.md, 21 snapshot goldens (the grip cells only),

recedes the other panes (InactiveDim)
Motion off|crisp|smooth|bouncy|playful is one parameter set (animation.Motion)
every fx animation reads. One focus spring per pane drives both the lift and
the dim, at the flavour's pace; a grid snaps.
Lift drops glow and surface. A shadow falls on pane bodies and rails only,
capped so text and the selection keep min(contrast, 4.5); rim is a hairline
along the focused tag's top. auto is a shadow on a light page; on a dark page
the core recedes the unfocused panes' text (InactiveDim, ported from 2e4d97f,
default 30 under auto) with the same floor. Tests: focused text contrast is
never below unfocused in any style, dim or theme; the focused pane's cells and
tag are untouched by a dim.
Shared files: src/config.zig, src/builtins.zig, src/ninep/ctl.zig,
src/surface.zig, src/detached/wire.zig, docs/config.md,
test/snapshots/builtins.snap (one more wheel for the longer help).

The scroll margin reveals text; with none off screen there is nothing to
reveal. ensureCursorVisible and a centred look both leave such a pane at its
top. A longer file keeps helix's clamp (hxdiff and hxparity unchanged).

makenewwindow puts them
Newcol makes an empty column; closing a column's last pane leaves it empty with
the keyboard on its tag; Delcol and Joincol alone take a column away; the
session's last pane closing quits. The +New stand-in and replaceStillborn /
stillborn_joiner are gone. Every new pane goes through exec.placeNew, which
follows acme's makenewwindow (active column, empty column whole, blank space,
halving the biggest) or, with Placement pardes, the old rules. ColumnTags is
gone: column tags are always shown. A grip drag shows acme's box cursor.

A script holding serials from before a Restore could not find its panes: the
replacement numbers them afresh. The dump now keeps each pane's serial (0 in
older dumps), and the replacement's log says `restored <old> <new>` for each
after its `restore <path>`.

After Restore a dogfood agent's command panes were fish shells under a stale
`(make) exit 0` tag. The dump's terminal record now keeps a command pane's
line and status, and Restore brings it back done: what it printed, its exit,
no shell and no rerun.

A dogfood agent's `Tty bash` pane came back from Restore running fish: the
dump kept its directory but not the shell it was opened on. The dump's
terminal record now carries that shell (empty for the configured one, as
older dumps read), and Restore starts it again.

A dogfood agent's background jobs died when the command that started them
finished, even under nohup. The command's shell leads its terminal's
session, and on its exit the kernel hangs up the terminal's foreground
group, which with job control off is the shell's and every job's. The line
now runs with job control on (bash, sh, dash, zsh, ksh -m; fish status
job-control full), so a job has a group of its own and lives on, printing
below exit N, and survives the pane closing. While a job holds the pty the
pane is not reused, so the directory's next command gets a second pane
(cmdexit's golden, re-recorded by name).

acme's frame wraps a tag at its right edge and the window grows to show
every row (wind.c wintaglines); Tagup/Tagdown shrink it to one row and back.
Pane tags used to be one row, scrolled sideways to the caret. Now a tag's
lines wrap at its width (one cell kept for the caret past a full row) and it
starts expanded; insert-mode Up on the first row collapses it, Down on the
last row expands it, and Alt-Up/Alt-Down do so in either mode. A word the
wrap breaks across rows is still one word to a click and a selection.
Column and workspace tags keep scrolling sideways.
Tests read body rows relative to the body's first row; the 41 snapshot
goldens that moved were re-recorded by name after a programmatic check that
each differs only by body rows shifting under the taller tags, and twelve
scripts whose clicks targeted fixed rows now click the same text.

miss is said, logged and reads back empty
Round 6: look calc.py:/return a/ was a word search, since a blank ended the address; calc.py:99 past the end focused the file and said nothing; and /look still read back the pane before a miss. A pattern after the colon may now hold blanks; file:N selects the line, newline included, as acme's does; a line past the end opens and focuses nothing; and every miss (no match, a bad address, a line past the end) says so, logs err <serial> look: why, keeps the selection, and leaves look reading back empty. Documented, with file:0/re/ for the first match, since acme evaluates the address from the file's dot. Five goldens change: a look at file:N now selects the line.

The grip button now shows a pane's unsaved text in every state, as acme's modbutton does, and acme's tag has no asterisk. The computed prefix is the name alone, so tag reads, event offsets that count the path and the tag's text lose the " *". dirty, index's flag and the refuse-once guards are unchanged; a dump from before still restores its tags past the old mark.

A B1, B2 or B3 drag over several lines took the same columns from every row, a block. acme's sweep is a stream (libframe/frselect.c:115-140, frselectpaint; acme text.c:881, textselect): the first row from the press to its end, the rows between whole, the last from its start to the release. edit.sweepCols says which columns of a row a sweep takes; the captured spans, the text a sweep yields (copy, chords, B2 and B3 operands, a terminal's automatic yank) and the highlight all follow it, in bodies, multi-row tags, terminals and text-rendered PDFs; a row the sweep runs through is highlighted to the edge, and rows after the first leave out the line numbers. Native PDF selection was already MuPDF's stream. No pane keeps a rectangle. exec-bigdrag's golden changes: its middle sweep now runs whole lines.

one undo step
Over 9P a rename everywhere was a loop of addr and data writes. Edit, from a tag, a pane ctl or exec, parses sam's commands as acme's edit.c does and runs them as ecmd.c does against the text as it was, collecting the changes in order as elog.c logs them and applying them at once: addresses (the addr file's, line:col included), x y g v c a i d s p = m t, u alone, and { }. One undo step; any error, in acme's words, changes nothing, fails a ctl write and is logged. p and = print to the directory's +Errors. Left out, and said: the file commands, the pipes, \1-\9 (mvzr keeps no submatches), and changes out of sequence, which acme applies with a warning.

dirty compared revisions only, so undoing to the save point, or typing the text back, left the pane dirty. The saved text's hash is kept from the first edit after a save or load, and an edit that makes the text equal to it marks the pane saved again, as undo to the save point does in acme.

step its body
Over 9P there was no way to take back an edit: acme's Undo and Redo were keys only. They are now pane builtins, reached from a tag, a pane ctl and exec, and listed in /commands. They are not added to the default tags, which would change every tag.

A shell now answers Host.now, its monotonic clock in ns, and the pump
advances core animation to it: one .tick per whole 16 ms frame since core
time last stood still. The same animation therefore takes the same time at
60, 120 and 144 Hz, over ssh and after a slow frame (the GUI's re-armed
clock ran them ~25% slow at 144 Hz; the tty's post-frame sleep drifted).
nextWake() lists every core animation in one place: a frame from now while
anything moves, the end of the wait while something only waits (a message
lingering, the look-hover delay), null when idle. Shells sleep exactly that
long, and a wait is jumped to its end in one step, so an 800 ms linger
costs one frame instead of fifty. An overshoot under 1.5 ms after a step is
let go: at 60 and 120 Hz every display frame takes exactly one step (a 16 ms
frame against a 16.67 ms vsync would otherwise double-step every 24th).
The six tick drivers are gone: tty's timer thread only times the wait,
interruptibly (a newer, shorter request cuts short a sleep still timing a
longer one); the GUI's
AnimationClock, web's JS tick bank (pardes_tick now takes rAF's timestamp),
the detached server's and the board's ticks; grid mode steps a virtual
clock straight to each wake. PARDES_TEST_CLOCK, set by the snapshot
harness, gives tty and the detached server the same virtual clock.
Every stepped frame is drawn. The old pump never drew the last frame of a
fade (a .tick asks for no frame, and the fade was over by the check), so a
theme switch stopped at 9/10 of the way until the next input: theme.golden,
themesel.golden and the GUI's acme-light scene move to the theme's true
colours, and nothing else changes. The frozen previous grid is captured only
while a panel transition is chosen, not on every idle frame.

$ was a second key for line end, which helix never meant: in helix it is
shell_keep_pipe. It now arms the pipe prompt with a $ marker, runs the
command once per range with that range's text on stdin, and keeps the ranges
it exits 0 on; the primary stays if kept, else the last kept range takes
over, and keeping none changes nothing. The runner's answer is all or
nothing, so the command runs in a subshell whose status is echoed as its
output. Line end stays on helix's own gl and End; the snapshots, tutor and
docs that pressed $ for it press gl.

one focused before
Dogfood closed a pane in one column and focus jumped to another column, only because that pane was focused last. Now removePane decides for every route (Del, a ctl del, a command pane's end, a 9P remove, a stillborn scratch replaced): the pane that grew into the rows, or the scratch standing in an emptied column; removeColumn gives it to the pane level with it in the column that takes the width. Closing an unfocused pane leaves focus alone. The per-caller focus lines in Del and replaceStillborn are gone, and so is prevFocus.

Only a reused pane showed '% line' above its command, so the first command's
output stood with nothing saying what made it. Every command is echoed now,
the first too. The goldens of chordcut, cmdexit, cmdword and layout-open gain
that line and the rows below it move down one.

language's files
Repl python in a terminal's tag or on its ctl binds it (Repl - unbinds, Repl
bare says the binding, the same word again changes nothing), with an id,
python-a, python-b, in its tag. An exec made by a gesture on the body of a
file in that language -- a middle click or the execute key, on any text, a
single word too -- or on the REPL's own body is typed into it, bracketed if
its program asked for that, else line by line with a once-said warning for
Python's blank lines, then Enter; the message row says -> python-a in the
tag's name tint, the log send <from> <to> <id>. Several bound for the
language: the pane asks which on its notice band, as Del asks, one key
answering, Esc none, nothing remembered. The gesture is known where it is
dispatched (mouse.zig, the execute key), so the tag's words, Exec <text> run
by name and a command word @`cmd` stay commands, and a 9P exec is never
sent. A finished command pane is no REPL; bindings are not dumped. The docs
spell out the escapes, the pdb and input() caveat and the no-bracketed-paste
papercut.

A job left in the background (sleep 100 &) held the pty open, so the pane
stayed running and the child a zombie until the job ended; a command that
closed its terminal and ran on got its end of file at once, the host waited
100 ms for an exit, reported exit ? and hung it up. Now each command's child
is watched on a thread (waitid with WNOWAIT, so its pid stays its own until
the host reaps it), and the host tells the core the exit from that: after the
pty's end of file, so the output before the exit is in, or 50 ms after the
exit without one, a job holding the pty. The pty stays open until both, so a
command that let go of its terminal is never hung up by it. All four front
ends; a host that cannot start the watcher reads the exit at end of file as
before. Tests: host_io's for both cases, and cmdexit.snap end to end.

A terminal's tag said Tty whatever shell it ran. The host's acknowledgement
of the shell it forked now sets the word to Tty+<shell>, tinted like the tag's
name. Word+arg is taken as Word arg, one word a tag can hold and a click can
take whole (+ is a word character), so Tty+fish opens a terminal on fish, as
Tty fish does; Tty takes the shell as its argument, which the host forks for
that pane instead of the configured one. Every snapshot whose screen shows a
terminal's tag changes: 69 goldens, re-recorded by name, whose 297 changed
lines are all Tty becoming Tty+bash (the harness runs bash), the cursor
columns and style spans that moved with it, or that text cut at a pane's
width.

shell's prompt
A middle click, an exec write or a tag word that no builtin knows was typed
into some terminal for the pane's directory, sharing whatever state that
shell was in and answering nothing, so a misspelling vanished into a shell.
Now only a line clicked at an interactive terminal's prompt is typed there.
From anywhere else it runs as a command pane: a terminal whose child is
$SHELL -c the line in the pane's directory, full emulation, which shows its
output and then exit N from the host's reaping of the child, and stays. A
finished command pane is the next command's for its directory, which runs
below what it showed after a '% line' line (acme appends to +Errors and never
clears it, util.c:213); a running one gets a second pane. Kill ends a command
pane's whole process group, the log records run and exit, exec reads back the
command pane's serial, and a line is at most 1 KB, read off the pane as the
host forks rather than carried in every spawn effect. ttyForDir's search for
a free shell is gone. The goldens of chordcut, cmdword and layout-open change
where a file's exec now opens a command pane, and ttytaken is rewritten to
exec from the terminal itself; docs/open-questions.md records the decision.
