* Only a write logs an err: a refused open or truncation, create or remove, or ↵Gabriel Schneider3 days
| | | | | | | | 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 Schneider3 days
| | | | | | 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 Schneider3 days
| | | | | | | | | | | | 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 Schneider3 days
| | | | | | | | | | | 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 Schneider3 days
| | | | | | | | | | | | 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 Schneider3 days
| | | | | | | | | | | 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 Schneider3 days
| | | | | | | writeCtl never cleared what the last write touched before its lines ran, so `New` through col/<n>/ctl read back the earlier write's serial too. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* New from a column's exec makes its scratch in the session's directory, as ↵Gabriel Schneider3 days
| | | | | | | | | tagexec's does A word run from a header runs in the session's directory (execDir), but New named its scratch after the pane with the keyboard. Co-Authored-By: Claude Opus 5.5 <[email protected]>
* One rule for failing builtins: the write fails, one err, no msgGabriel Schneider3 days
| | | | | | | | | | | | | | | | 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 Schneider3 days
| | | | | | | | | | | | 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 Schneider3 days
| | | | | | | | | 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 Schneider3 days
| | | | | | | | | | 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 Schneider3 days
| | | | | | | | | | 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 Schneider3 days
| | | | | | | | | | | | | | 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 Schneider3 days
| | | | | | | | 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 Schneider3 days
| | | | | | | | | | | | | | 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 Schneider3 days
| | | | | | | | | | | 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.

* Columns are named by stable serials over 9P, as panes areGabriel Schneider3 days
| | | | | | | | | | | /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 Schneider3 days
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.
