* A ctl refusal quotes the offending word alone, everywhere: wrong #args in ↵Gabriel Schneider36 hours
| | | | | | | | | | | | control message "Newcol", not "Newcol 2" Some refusals quoted the whole line, arguments and all ("Newcol 2", "Verbose maybe", "lock x"), others the word alone ("Theme", "Mount"), so a script matching one could not match the other. Every ctl refusal, the root's, a pane's and a column's, now quotes the message's word alone, and one too long to quote whole gives up its middle. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Views generated by each read stat 0, as acme's do: data, xdata, index, ↵Gabriel Schneider36 hours
| | | | | | | | | | | | layout, recent and listeners; fs.md says which files have real lengths A stat of index, layout, recent or listeners built the whole view to count it, and data and xdata reported the body's length though a read answers what addr selects. Those now stat 0, as screen and pane/new already did, and fs.md lists the files whose length is real and says to read the rest to the end. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A shell command from the workspace's or a column's tag runs as a command ↵Gabriel Schneider36 hours
| | | | | | | | | | | | | | | pane in the session's directory, never typed into the terminal with the keyboard A command clicked in a header tag, or written to /tagexec or a column's exec, was typed into the active terminal when it sat at an empty prompt, so it ran in that pane's directory and left no run or exit record. It now always gets a command pane of its own in the session's directory, as acme's row and column tags have no directory but the session's. tags.md writes the rule down: pane words act on the column's active pane, a column's words on the column, shell commands as their own panes, and over 9P a pane's word is refused.

* Joincol is refused, as Newcol is, when the joined column cannot give each ↵Gabriel Schneider36 hours
| | | | | | | | | | | | | | | pane its tag and 2 rows Joincol moved every pane of the keyboard's column into the next one whether they fit or not. Two columns of two panes in a 12-row window became one column of four, wanting 12 rows where 10 were free, a layout that `size` then refused as it stood. Joincol now tries the join in place first (layout.joinFits: the panes and width moved, minimaFit asked, everything put back, nothing dropped or logged). A join that does not fit is refused, "Joincol: no space: the joined column cannot give each pane its tag and 2 rows". Co-Authored-By: Claude Opus 5.5 <[email protected]>

| | | | | | | | | | | | | a refused one stand A `>` to a tag that a client sends in several writes is checked a write at a time. When a later one is refused, the earlier accepted ones stay in the tag. Buffering the whole open to apply it or none would cost more than it saves, so fs.md now says what happens: each write stands on its own, and only the refused one changes nothing. A test covers a truncation, an accepted write, then a refused one. Co-Authored-By: Claude Opus 5.5 <[email protected]>

| | | | | | | | | | | | 4096 bytes fits `echo <4096 bytes> > tag` wrote 4097 bytes and was refused "over 4096 bytes", although a rewrite drops that one trailing newline and would have held exactly 4096. The limit now counts a truncating write's text without the newline it drops, for a pane's, a column's and the workspace's tag. An append still counts its newline, which it keeps.

| | | | | | | | | | | | | acme's placement does A pane/new whose column had no room was refused "no space for a pane in that column", even with another column holding a tall pane that could give rows. acme takes rows wherever a window has them before saying there are none. pane/new now tries the other columns as +Errors already did: an empty one, else its tallest pane's bottom half, last column first. It is refused only when no pane anywhere can give the rows. Co-Authored-By: Claude Opus 5.5 <[email protected]>

So the record read `err - col/1/tag: tag: no space: over 4096 bytes`. The text is now the reason alone, as the control-character refusal's is, and the record names the file once.

| | | | | | | | | | | | | | runs as nothing at an exec, a ctl or the init file DumpConfig's information lines ("Platform: tty", "Startup config: ...") began with words. Written back, as the report means to be, or clicked, each ran as a shell command or failed as an unknown control message. Each now starts with `# `. A line starting with `#` is a comment, as in a shell: it runs as nothing, silently, at an exec, at the root's, a pane's or a column's ctl, and in the init file. Documented in fs.md and config.md.

* A Newcol refused because the panes' tags would not fit logs its err alone ↵Gabriel Schneider36 hours
| | | | | | | | | | | | | | | | | and spends no column serial Newcol tries its column before keeping it: the new column is inserted, the panes' rows are shared out again, and where a pane would be left under its tag and two rows the column is taken back. The trial showed. insertColumn logged `newcol N` and the take-back `delcol N`, so a follower saw a column come and go around the err. Laying the column out also gave it a serial, so the next column made skipped one. The trial is now unannounced, since insert and drop have unlogged forms. A refusal puts the serial counter back where it was, after first giving every existing column its serial so the trial's is the only one spent. Only a column that stays is logged, and it gets the next serial. Co-Authored-By: Claude Opus 5.5 <[email protected]>

| | | | | | | | | | | | directory, not the keyboard pane's New, Tty and commands clicked in a tag no pane owns ran in the session's directory, but Help named its +Help after the pane with the keyboard, and Find walked that pane's directory. So the same click gave different results depending on which pane was focused. Both now take the session's directory from a header, through execDir as the others do.

* A column's and the workspace's tag read with no trailing newline, as a ↵Gabriel Schneider36 hours
| | | | | | | | | | | pane's does A pane tag read back its text alone, but a column tag and /tag appended a newline and gave a stat size one byte longer. So `$(cat tag)` agreed across the three kinds while `cat tag | wc -c` and a byte compare did not. All three now read the text alone, and fs.md says so. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* New and Tty run at /tagexec and a column's exec, and with no pane at allGabriel Schneider36 hours
| | | | | | | | | | | | | The words New and Tty make a pane in the session's directory, and fs.md already has them run at a tag no pane owns. But /tagexec refused New as a pane's word, since the workspace tag does not hold it. Every header exec also failed ENOENT when no pane was left, and Tty gave up when it had no pane to take a directory from. Now New and Tty are every tag's words. A header exec with no pane runs at the stand-in, as a click in the empty window's tag does, and Tty with no pane asking starts in the session's directory, as New's scratch does.

* A word at /tagexec or a column's exec that makes, acts on and focuses no ↵Gabriel Schneider36 hours
| | | | | | | | | | | | pane reads back nothing Newcol written to /tagexec read back `1`, the pane with the keyboard, which the word never touched. That was a pane word's fallback (a pane's exec answers the pane it ran at) applied to a tag no pane owns. A word in a column's or the workspace's tag now answers the pane it made, refilled, went to or focused, and otherwise nothing. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Pane, column and workspace tags take one set of write checks, and a refused ↵Gabriel Schneider36 hours
| | | | | | | | `>` write leaves the tag as it was A column's or the workspace's tag took any length, so a write past 4096 bytes went in and a later Dump failed on it (bad dump tag), and a truncating open wiped any tag before the write after it could be refused. The column and workspace tags now refuse what a pane tag refuses: the 4096-byte limit (ENOSPC, tag: no space: over 4096 bytes) as well as the control characters they already did. A truncation of any of the three is held until the write after it is known to fit, and done with it; a refused write drops it; a close or read with no write after it does it then (so `: > tag` still clears). A test runs a truncating write too long, a control character and a bare truncation at each kind, and Dumps after. docs/fs.md says so. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Only a write logs an err: a refused open or truncation, create or remove, or ↵Gabriel Schneider36 hours
| | | | | | | | a write to pane/new, is its error alone, and every refusal is said in words The one-failure rule is a write's. A refused remove, pane/new's open refused for want of a slot, and an OTRUNC open's refused truncation (data's after a failed addr) also logged an err, and a reply carrying only an errno reached the client as the C library's text (Operation not permitted). tree.handle now gives such a reply Plan 9's words, chosen so 9ns maps each back to its errno (EPERM's to EACCES, as Plan 9's does), and serveFs logs errs for writes only, not a write to pane/new, which is only read. docs/fs.md and the 9P skill say so, and that a look miss quotes what was written.

* A builtin's Verbose announcement is the message row's alone, never loggedGabriel Schneider36 hours
| | | | | | With Verbose on by default, /log filled with msg - DumpDir, msg 4 Grep and the like, with machinery to take an announcement back out when its builtin failed or said something itself. A msg record is now only something said; the take-back machinery goes with it. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A tag write refuses NUL and the other control characters; a Dump that fails ↵Gabriel Schneider36 hours
| | | | | | | | | | | | 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.

* Edit written to /tagexec or a column's exec is refused as the other pane ↵Gabriel Schneider36 hours
| | | | | | | | | | | words are 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. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Every EINVAL a write gets says why; DEL in an exec or look line is a control ↵Gabriel Schneider36 hours
| | | | | | | | | | | | character An empty name, a word written to log other than follow, a data, sel, dot or dirty write to a pane with no text, a truncate other than to zero, and a control character in a look line written through a held open were refused with no words, logged as `Invalid argument`. Each says its reason now; and DEL is refused in exec and look lines as in names. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A pane's word written to /tagexec or a column's exec is refused, not done at ↵Gabriel Schneider36 hours
| | | | | | | | | | | the focused pane Undo, Msg and the other pane words written to a tag no pane owns ran at whichever pane had the keyboard. They are refused as the root's ctl refuses them, EINVAL; the tag's own words (a column's New, Tty, Find, Grep) still run. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A column ctl write reads back what it touched aloneGabriel Schneider36 hours

* One rule for failing builtins: the write fails, one err, no msgGabriel Schneider36 hours
| | | | | | | | | | | | | | | | 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. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A column's ctl refuses as the other ctls do, and a bare answer says what it ↵Gabriel Schneider36 hours
| | | | | | | | | | | | takes A column's ctl refused an unknown word in words 9ns maps to EIO, and took New extra as New. It now refuses the word as unknown control message (EINVAL, as the root and pane ctls) and any word but Tty with an argument as wrong #args. A bare answer on a pane's ctl says answer takes a choice or -, not unknown control message. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A command run from a column's tag gets its pane in that columnGabriel Schneider36 hours
| | | | | | | | | A command from a column's tag ran in a command pane at the foot of the last column, however far from the tag, and could reuse a finished one anywhere. It now goes to the tag's column, under both placements, and reuses only a finished command pane in that column. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Words from the workspace and column tags run in the session's directoryGabriel Schneider36 hours
| | | | | | | | | | A command or Tty run from the workspace tag or a column tag started in the focused pane's directory, though those tags have none of their own. As acme's row and column tags do, they now run in the session's directory, where pardes started (Pardes.sessionDir); a pane's tag and text keep the pane's. The same for /tagexec, a column's exec and ctl. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* An exec line over 1024 bytes fails the write, naming the limitGabriel Schneider36 hours
| | | | | | | | | | A command line longer than the 1024 bytes a command pane takes was said on the message row after the write had already succeeded. An exec write (the root's, a pane's, tagexec, a column's) now refuses it before anything runs, EINVAL with "a command line is at most 1024 bytes" and an err record; a builtin's line, a long Msg or an Edit block, is not limited. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* The workspace tag has /tagexec, every exec file reads back what it touched, ↵Gabriel Schneider36 hours
| | | | | | | | | | | | | | and a tag's words log as the session's /tagexec runs a word as a click in the workspace tag, as col/<serial>/exec does in a column's. A column's exec was write-only; it and /tagexec now read back the serials the last write touched, as /exec does. A click in a tag no longer goes to the focused pane's event reader, and what a word run from a column's ctl or exec or /tagexec says is logged msg -, not against the focused pane. The README, fs.md and the skill say so, and document the answer record. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* An error on a column's ctl, exec or rmdir names that file in the logGabriel Schneider36 hours
| | | | | | | | noteError named every column node col/<serial>/tag, so a refused ctl write or rmdir pointed at the tag. It now names col/<serial>/ctl, /exec, /tag or the directory itself. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A column has a ctl, an exec and an rmdir over 9P, and Restore maps its serialGabriel Schneider36 hours
| | | | | | | | | | | | | | 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. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* A focus write makes its pane's column the active one, and layout's active is itGabriel Schneider36 hours
| | | | | | | | | | | Writing a serial to /focus gave that pane the keyboard but left the active column where it was, so pane/new under Placement acme went elsewhere, and /layout's active named the keyboard's column rather than where a new pane would go. A focus write now sets the active column as the user's click there would, under either Placement, and /layout's active names the active column, which pane/new and a look place into. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* Columns are named by stable serials over 9P, as panes areGabriel Schneider36 hours
| | | | | | | | | | | /col/<n> named a column by its index, which shifts when a column left of it closes: exactly what scripts trip on. A column is now /col/<serial>, its serial kept while it lives and never reused; /layout lines give serial and index (`<serial> <index> ...`), active names the serial, /index's last field is the column's serial, and the log says newcol and delcol with serials. Docs, the skill and the tree's README say so. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* The tree serves the layout: /layout, /tag and /col/<n>/tagGabriel Schneider36 hours
A script could not see where the panes sit or edit the tags a person clicks in. /layout lists each column, its index, x and width in cells, current or not, empty or full, and its panes' serials, then the active column; /tag is the workspace tag and /col/<n>/tag a column's, read and written as a pane tag is (one line: a newline written in is a space, and a truncating write drops the one ending it); /index's lines end with the pane's column; the log says newcol <n> and delcol <n>. acme serves no column files, and the docs say so.
