Del of one twin asks nothing while another holds the text, Exit lists the text once, and a closed twin keeps a copy of its own until it is torn down. Both are in the index, each its serial, one name. An event reader on one hears no edit made through another (first cut).

* Builtins are chips that link to a glossary generated from the registry, and ↵Gabriel Schneider14 hours
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | commands are not run a second time 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.

* The init file reads past a UTF-8 BOM, and every line it fails is said and ↵Gabriel Schneider17 hours

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.

* A command or terminal pane refused for room is refused before anything is ↵Gabriel Schneider17 hours
| | | | | | | | | | | | | | | 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. Co-Authored-By: Claude Opus 5.5 <[email protected]>

* DumpDir refuses a relative directory and one that may not be written, up ↵Gabriel Schneider18 hours
| | | | | | | | | | | | | 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`. Co-Authored-By: Claude Opus 5.5 <[email protected]>

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.

* A Rename the server answers for this file alone, while other open files of ↵Gabriel Schneider18 hours
| | | | | | | | | | | | | | | | | 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. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Restore reads a clean file from disk, and an unsaved one whose file changed ↵Gabriel Schneider18 hours
| | | | | | | | | | | | | | | | | | | | | 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.

* Petscii, Palette, Ascii, PdfFit and PdfTint take the state their tag word ↵Gabriel Schneider20 hours
| | | | | | | | | | | | | 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 what it takes. Co-Authored-By: Claude Opus 5.5 <[email protected]>

| | | | | | | | | | | line past the end is said one way: `<file>:N has no line N`, for `:N` as for `file:N` lookAt dropped a trailing `:` from what it read but resolved the target from the text as written, so `@p33:` was `no match for "@p33:"`. And `:99999` said `address out of range` while `file:99999` said `has no line 99999`: a bare line number past the end now says the latter too. Co-Authored-By: Claude Opus 5.5 <[email protected]>

* /pager resolves its directory, `~` and `..` alike, and refuses one that may ↵Gabriel Schneider20 hours

The directory is now home-expanded and resolved before it is checked, and one that may not be written is refused as a file's name there is (fs.deniedAbove). `pardes -` run in such a directory (`git log` under /usr/src) asks for the session's +Pager instead, so its text is still paged.

* A Rename that previews other files answers its preview pane to the 9P write ↵Gabriel Schneider20 hours
| | | | | | | | | | | | | that asked it, and says on the message row that it previewed and applied nothing A multi-file Rename filled a +Search preview but the waiting exec write answered the pane it was asked from, and nothing was said. lspResponse now notes the pane it filled (fs.lsp_result); the write that waited for the answer reads that pane back, as a look or an exec answers the pane it went to, and the message row says `Rename: N edit(s) across files, previewed, not applied`.
