A ctl refusal quotes the offending word alone, everywhere: wrong #args in control message "Newcol", not "Newcol 2"

2026-10-01T03:12:17Z

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

Views generated by each read stat 0, as acme's do: data, xdata, index, layout, recent and listeners; fs.md says which files have real lengths

2026-10-01T03:12:17Z

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

A shell command from the workspace's or a column's tag runs as a command pane in the session's directory, never typed into the terminal with the keyboard

2026-10-01T03:12:17Z

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 pane its tag and 2 rows

2026-10-01T03:12:17Z

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

fs.md says that in a > to a tag cut into several writes, those taken before a refused one stand

2026-10-01T03:12:17Z

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

A tag rewrite counts its text without the newline it drops: echo of exactly 4096 bytes fits

2026-10-01T03:12:17Z

`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.

pane/new takes rows from a pane in another column before refusing ENOSPC, as acme's placement does

2026-10-01T03:12:17Z

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

A tag write over the limit is refused "no space: over 4096 bytes", so its err record says tag: once

2026-10-01T03:12:17Z

The refusal's text began with "tag: ", and the log's err record puts the file's name before the reason. 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. Co-Authored-By: Claude Opus 5.5

DumpConfig's lines that set nothing start with #, and a line starting with # runs as nothing at an exec, a ctl or the init file

2026-10-01T03:12:17Z

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 and spends no column serial

2026-10-01T03:12:17Z

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
