namespace's lowercase name
The last of the deferred renames, now that the tty and theme agents have landed: panes.terminal at its importers, the alias lines in Text.zig and File.zig and panes.zig's own uses following. dump.zig's Terminal struct, a dump record, is not this. The served sources list and docs/design.typ name the new file. test/perf.zig's references change, so the three perf baselines take its new harness id with their numbers as recorded. No behaviour changes.

lowercase name
The naming the split agreed on, deferred until now; panes.mini is its name at its importers. File.zig keeps its alias line (const Mini = panes.mini) so the file another agent is working in changes by that line alone. The served sources list and docs/design.typ name the new file. No behaviour changes; test/perf.zig's two references change, and since the perf harness is keyed by its own text, its three baselines are recorded again (under other agents' builds, so a little slower).

middle to …
An Rerror carries 128 bytes (Plan 9's ERRMAX) and the engine cut longer text there, and a builtin's failure was first clipped between words to 256 with ...: either way the end, which says why, was what went. tree.handle now fits a long reason by cutting the middle of its longest path, else of the whole text, on a character boundary, and reportFailure fills its buffer the same way.

Delcol's refusal opened +Unsaved, placing a pane in the layout it was refusing to change. Its unsaved records and notice say which panes; the list pane is left to the refusals of the other words.

names capitalised
Mini needs a file but did not say so, so a bare Mini ran and failed EIO. It now requires its argument, refused wrong #args (EINVAL) as every such word is. Its failures, Find's and Grep's start with the builtin's own name (Mini:, Find:, Grep:), as the others' do.

is a real refusal or says why it cannot fire
A sweep for round 23's crash: a run's answer (pty/run) was bufPrint'd into 48 bytes with catch unreachable, so a foreground program's long name (macOS gives up to 32 bytes) panicked; it now cuts at the room, keeping its newline, in 96 bytes. The rest were numbers into buffers sized for them, a braille codepoint, pthread calls on the queue's own mutex, and pdf_view's resolved outline entries: each now carries a one-line comment saying why it cannot fire.

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 (...).

path says why
The theme is read when the host performs the request, after the write had been answered, so a missing file or a bad theme only showed a message; and a path not ending .zon said only invalid theme path. Load failures are now the waiting write's (late, as a Save's), and the path refusal says a theme file is a .zon.

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.

On a terminal, Fonts written to an exec was no builtin there, so it ran as a shell command and ended exit 127; ctl said unknown control message. Both now say Fonts is GUI-only, invalid here (a builtin another platform's build has, not in this build).

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.

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.

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.

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.

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.

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`.

err never cuts a list
Exit's refusal joined every name into one err, cut at the record's cap in
mid-name, so a script could not tell which panes held it up. Each pane is
now an `unsaved` record before the err, and the err names the one pane
or counts them: `4 unsaved panes: Modified (Exit again to discard)`.
Restore, Del and Delcol refuse the same way.

87 of the listed words had no description: settings have no doc comment
to read, so each now carries a one-sentence doc, and the builtins without
one got theirs. Exit's no longer names an internal function, and Repl's
first sentence is short enough to be read whole.

write's does
Under the one rule a click fails its write too, but only a ctl write
assembled the `<a>, <b>: Modified (Exit again to discard)` line: a click
failed with the first pane's name alone.

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.

An exec write does not fail for what its command says, so an a/c/i text
or { group cut short by a write that ended early was only a msg, easy to
miss. Over 9P, that failure (a truncated write, not a command's) is now
logged as an err record naming exec; the pane still says it.

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.

Exit, Restore, Del and Delcol share one list (warnModifiedIn), but it was
built in 256 bytes, so with a few long paths a +New scratch near the end
fell off Exit's and Restore's, which list every pane; and several +New
panes were indistinguishable. The list is built in 1024 bytes (the
write's error is still cut to fit, between words), and a scratch is named
with its serial, /dir/+New (pane 12), the same everywhere.

The refusal listed every language and was clipped to fit, ending mid-word.
It now names six, those that start as the word did first (pithon:
python), says how many more, and points at docs/tags.md, which lists them
all.

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).

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 pane's Undo or Redo with no step left did nothing and said nothing. It
now says "Undo: nothing to undo" (or Redo's) as a message, not a failure,
so a ctl write of it still succeeds as acme's silent Undo does. The docs
give the 256-step history.

The GUI golden's wide-glyph pane, renamed and never edited, was refused by
Del as modified, and every frame after it kept the pane. A rename marks a
pane dirty, but its text is what it loaded: the check now asks whether the
text was ever edited (its first edit keeps a hash of what it had), not only
whether it is dirty, as get's refusal does. Tests that faked an edit by the
dirty mark alone now fake the hash too.

Sixteen panes was far too few for a real session. MAX_PANES is now 64 on a
desktop and stays 16 on the board; the 48 more slots cost about 3.7 KB each
in fixed tables (the core 1.33 to 1.45 MB, its surface 19 to 72 KB), and a
pane itself (84 KB and its terminal) is allocated only when it opens. At the
cap, pane/new fails with `pane/new: no pane slots: 64 max` and an err
record rather than a bare ENFILE, a 9P look or exec that would open a pane
fails its write with the same words and reads back empty, and New, Tty,
Tutor and Alt-n say it on the message row (their ctl writes fail with it).

acme's Del asks winclean first and Delcol colclean (exec.c del, delcol):
unsaved text is warned about, and the same word again closes. pardes closed
at once. Both now refuse once through the one-warning-per-word mechanism
Exit uses, from keys, tags, exec and ctl alike. A pane dirty only by a
rename, or an empty one that never held a file, has no text to lose and is
not asked about, and a scratch or a command's output under 100 bytes is not
either, as acme's winclean passes a small unnamed window.

Their refusal named only file panes, so text typed into a +New scratch went
unasked about and was lost. A scratch with text counts as unsaved as a file
does (acme's winclean asks about an unnamed window too). The refusal a ctl
write gets now reads as the message row does, `<names>: Modified (Exit
again to discard)`, instead of a second "discard them all" wording.

A Dump into a DumpDir it could not write, or a Restore of a file that is
not a dump, answered a ctl write with rc 0 and only a message, and the
Restore warned about unsaved panes before it ever looked at the file. The
hosts' dump write now fails the waiting 9P write with EIO (the late failure
a Save uses), naming the path and the reason in the log, and Restore parses
the file before its unsaved-panes refusal, failing with `not a pardes
dump`.

Bare Placement and BootShell flip, which is pardes's convention for a word
that chooses (Crt does too), but nothing said so, and "bad value in control
message" never said what would do. A refused value now says `takes acme,
pardes` (every switch and choice setting), /commands lists each such
setting's values in a fourth field, and config.md and fs.md say that bare
steps to the next. Motion and ShaderAnimation stepped nowhere bare and now
step like the rest.

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,

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,

The user wants Lift to read on dark themes, where a shadow has nothing to
darken. `Lift shadow|surface|rim|glow|auto` (`on` is auto, bare flips
auto and off): surface lightens the lifted part's ground about 5.5%
(Material-dark), rim is a thin soft light off its top and left edges,
glow a faint halo in the theme's accent (Chrome.accent, the focused box
colour), auto a shadow on a light page and surface with half a rim on a
dark one (by the page's luminance). Rim and glow are the soft kernel in a
light colour (no pre-warp: coloured light is laid on as is, within §8.2's
budget); each style is capped per theme so text keeps min(its contrast,
4.5) (tests: darkening and lightening over the native themes). The style
travels in the palette (Chrome.lift_style, one byte on the wire). Config
reports and ctl reads `Lift <style>`.
Shared files touched: config.zig, builtins.zig, ninep/ctl.zig,
detached/wire.zig (palette byte), gui.zig. Not touched: pardes.zig,
Messages.zig, mouse.zig.

`Lift` (a GUI toggle, capability lift) lifts the focused pane on a
critically damped spring (animation.Spring: closed form, about 240 ms to
settle, velocity kept across retargets, settled = no frames) and floats
notices. The core puts the lift on the regions (Region.lift, on the wire);
the GUI casts from it: a soft shadow is decor, an erf rectangle on one
quad grown by 3 sigma (decor.frag, flag 0x10000000), in the quad's own
space so a track's transform carries it; darken-only, the caster's rect
left alone, alpha pre-warped for linear light and IGN-dithered. Cast last
in its group, so a neighbour's rails and rules darken with its text; a
notice's before its rule. Strength is capped per theme so text over the
darkest shadow keeps min(its contrast, 4.5) (test over the native themes).
Opt-in until the focus lift/dim default is decided. Feel review material:
docs/effects.md. Test-mode PARDES_TEST_SERIES keeps every captured frame.

set, flipped bare, and reported by one arm.

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 could not answer the several-REPLs question, which only a key
could. Every question a pane asks on its notice band (which REPL takes an
exec, Del's side from the keyboard) is now logged as `ask <serial> <what>
<choices>`, and `answer <choice>` on the pane's ctl answers it as that key
would, `answer -` taking it back as Esc does. One function answers for a
key and for the ctl.

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.

just the first
Each pane got its own message, but a ctl write fails with its first error only, so a script was told about one pane, and the next Exit discarded both. The refusal now lists them all, as acme's rowclean does, and says the next one discards them all.

nothing
A look at `file:/re/` or `:/re/` searched for the words instead of addressing, and a miss left an empty +Search pane and a cleared selection, while a hit answered the +Search pane on /look. Now an address after a colon (acme look.c:450) is evaluated in the file from its dot; a miss says no match and leaves the panes and the selection alone; a hit reads back as the pane the text is selected in. Both live in lookAt's one flow, so they are one change.

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.
