the virtual filesystem is drawn as a tree
#word draws a builtin as a chip on the tag's ground over a rule (Look and
Exec in acme's look green and exec red), a <code class="word"> in HTML,
and links it to its entry in a new Builtins chapter wherever that
chapter is in the same output (the book, the site). The chapter is
drawn from docs/typ/builtins-tty.json and builtins-gui.json, which
`zig build builtins-json -Dplatform=tty|gui` writes from the registry
and the Help rows (src/builtins_json.zig, tools/gen_builtins_json.zig;
summaryOf in ninep/ctl.zig is now pub); style.typ merges them, marking
the window-only words. The doc steps refresh their build's file first,
and each build's unit-test fails when its file is stale. Everyday words
first (`everyday` in style.typ), then groups by leader prefix as Help
has them, then settings, the words with no path, debugging and
internals, and last an A-Z index of every word. `zig build book` joins
the doc steps.
#fstree draws a directory tree with its connectors, a description
column and links to the sections that document each file; reference.typ
draws the served tree with it, each pane, pty and column file on its
own line, and a test in config.zig checks it against ninep/tree.zig's
files both ways. The cheatsheet has a two-level version. On the site
the tree reads as `tree` text in w3m and wraps descriptions under the
names on a phone.
The site's tutor draws its B1, B2, B3 and 1-2 chords as mouse glyphs;
the landing credits Plan 9 and acme, as does the book's title page;
install.typ no longer lists the mirrors (the footer does).

last line is answered at once: the line runs at the editor's next step
A shell's truncating open of exec (or look, ctl, log, pager) sends a
setattr that changes nothing; it waited for the editor to be quiet, and
through a 9ns mount that quiet could never come: 9ns answers nothing else
on the mount while the setattr is out, and the editor's step may be out
reading a pane's file through it. This was the "truncating open of exec
hangs, only in selfmount" mystery. Only a truncate of a pane's file or a
tag waits now.
A close holding a last line with no newline hands it to the editor's step
(tree.runClosedLines, beside fillClosedPagers), as a /pager close does, and
is answered at once; a refusal is the log's err.

A setting changed in the init file took effect only at the next start.
The host's Save now hands a written init file's text back to the core,
which applies its setting lines again (each idempotent), with the same
notice and err for one that fails; a command line in it (`Newcol`)
belongs to the start and is left alone.

A BOM made the first word unknown, a word no builtin has was skipped
without a word, and a setting that refused its value said nothing (the
init file ran with announcing off). Each failing line now leaves a
notice and an `err - init file line N: <why>` record; `#` still starts
a comment only at a line's start, so `#ff0000` stays a value.

klingon` is invalid (EINVAL), its message citing no doc path
A refused answer quoted the word `answer`, not the choice refused. A
`name` with nothing after it was an unknown control message. A Repl of
no such language failed EIO with a pointer into the reference; it now
says `invalid language` (EINVAL, here and through a mount) and how many
more there are. A builtin's failure that says invalid anywhere is
EINVAL, as 9ns reads it.

logged or answered of it, and a serial is never handed out twice
A command pane with no room logged `new N` and `run N ls`, was answered
to its exec, then went with `del N` and no `exit N`; and sync gave N
back (`next_serial -= 1`) to the next pane made, so a script holding N
found another pane under it. Tty did the same. Both now take a refused
placement back at once, before the run is logged or the serial answered
(the pane was never announced, so it leaves no record), and fail the
write with no room. The decrement is gone: gaps are fine, and a serial
once said names one pane for good.

because a write was short: a long line cut by a mount is one line
A write shorter than its message, and not a multiple of 4096, was taken
as whole, its tail a line. 9ns cuts a FUSE write of up to 512 KiB into
65512-byte Twrites, the last one short, so a 600 KiB `Edit ,c/.../`
arrived cut and its tail ran as an unknown control message; the 1 MiB
refusal failed the same way. Each open now holds a partial line until
its newline, or its release, which ends the last line; an Edit block is
whole when it closes, as before. A name write with a NUL still fails
its write at once. selfmount writes a 600 KiB Edit line and a 1.1 MiB
line through a real 9ns mount; building.typ says how lines are cut.

A dial with a `!` and no `/` that was neither tcp!, quic! nor unix! was

It is now refused as the malformed address it is, before any dial. A
path with a `!` in it still dials.

front, and a Dump that could not make its directory says permission denied
A relative DumpDir was resolved from wherever pardes started, and one
under a directory that may not be written was taken, the Dump failing
later as `no such directory`. DumpDir now takes an absolute or `~` path
whose nearest directory there may be written, and refuses any other with
what it takes; a Dump refused by a directory above says permission
denied (fs.deniedAbove), as a Save does.

maps, and the rest of it is dropped through its newline, not run as a second line
Past the 1 MiB a line may hold, the write that crossed it was refused
and the pending text dropped, but what followed of the same line was
taken as a new line and ran when its newline came: a second refusal,
`unknown control message "zzz…"`, and a second err. The open now drops
the rest through the newline, and the refusal says `invalid write: a
line or Edit block over 1 MiB`.

Neither showed in the tag or the ctl, and a Restore brought a PDF back
at width fit and the default tint. The ctl read ends with `collapsed`

hits`, `N files read only in part (first 256 KiB)`, `walk cut at N entries`; one that finds nothing leaves the +Search as it was
Grep reads 256 KiB of a file and stops at 512 hits, and its walk at
20000 files or 100000 entries; Find stops at 512 names. A cap hit was
silent, so a match past one read as `pattern not found`. The walk now
notes each cap it hit (fs.WalkNotes) and the +Search says it in a line
under the hits, as it says directories skipped; a search that found
nothing but hit a cap opens the +Search with those lines, not a miss.
A Find or Grep that finds nothing and passed nothing over leaves the
directory's +Search with the last search's rows, its failure saying so,
where it used to empty it.

its language say the name, is previewed, never applied; Lspwhy shows the files synced first
zls renaming at a declaration answers with that file's edits only,
cold or warm, whatever it was told of (checked against zls directly:
from a call site in main.zig it renames both files, from the
declaration in util.zig it never does), so the first Rename applied in
util.zig and left main.zig broken. The client now looks for the old
name in the other open files of the language; when one says it and the
answer left it alone, the edits are a preview with a row naming each
such file, and the message row says the server renamed in this file
only. Lspwhy carries the open files too, so its trace shows `synced X
first` for the query it explains.

since the Dump is said changed, its first Save asking before overwriting it
A Restore put back the dump's copy of every file pane and armed the
watch with the disk as it now was, so a file changed on disk after the
Dump came back as its old text, marked clean, and the next Save wrote
the old text over the new without a word.
A clean file pane's text is now not in the dump: Restore reads its file
(an older dump's copy is read past too, and used only when the file is
gone). An unsaved pane keeps its text once, base64, the plain copy beside
it dropped, with the hash of the file it was read against
(`disk_hash`); a Restore that finds another there says the file changed
on disk, and Save asks once before overwriting it, as for a change seen
while it was open. file_watch.zig's own tests were never collected (no
test root imported it): main.zig's test block does now, and the restored
watch test says what a clean restore now reads.

names, set rather than flipped: `Petscii on`, `Palette terminal`, `PdfFit width`
Each could only flip, so a script had to read the tag to know which way
a write would go. Each now takes an optional argument, the value its
tag word shows (on|off for Petscii and Ascii, commodore|terminal for
Palette, width|height for PdfFit, disabled|filtered|full for PdfTint),
and sets it; bare, it flips as before. Anything else is refused with

The tests' request helper asks cloud9's fs.enameErrno, the rules 9ns
turns a refusal's words back into an errno with, for every EINVAL and
ENOENT a request is refused with, and fails the test when a mount
would hear another (EIO, mostly): "this pane has no text to address"
was one. The re-pinned cloud9 maps acme's own refusals, which pardes

addresses out of order, range past end of body and the rest.

A Restore makes a fresh core, which started at the default theme and
asked for the dump's ThemeFile; when that file had broken since, the
failure reverted to what the fresh core had loaded, nothing, and ink

the theme the old session showed and the file it loaded (and its Theme,
unless the dump names one), so a failure there changes nothing.

A prompt mark there now counts. A run sent at such a prompt leaves the

so its output lands on the primary screen and is read whole, not
`exit 0 cut` with nothing. Busy there with no prompt drawn, and no
