An Edit filter that can never be reaped no longer holds the Edit's answer: at the limit the command's group is killed and reaped off the answer's path, the stdin writer owning its input, so a filter writing its own ctl with > or >> answers EIO at 10 s instead of hanging; a running Edit keeps its own copies of the names it reports, and the panes it changes refuse Del, delete, rmdir, Undo, Redo, Get and Zerox (busy, EBUSY); e and r say unreadable files in Get's words; the reference says both sides of a filter's own ctl write need <>

Get of a file not there, or of a directory, says so before asking about unsaved edits; the init file saved in a pane logs a bad line as err - init file line N, as startup does, its commands still not run again

Round 39's small ones: a name write past its one line is refused by that write; Get and Edit's e load over a scratch under 100 bytes unasked, as Del closes it; Putall saves a Zerox pair once; bare Tab on the root ctl says the width as from a pane, and a ctl check of Tab no longer sets it; a directory read is "is a directory" (EISDIR), an unreadable file "permission denied" (EACCES), Incl of a file "not a directory" (ENOTDIR), and a device "not a regular file", never read to the stream limit

A file whose disk text is what its unsaved pane was read or saved as is no change on disk: an Undo back across Get file or Edit's e to unsaved edits no longer says the file changed, and Save writes it

Edit's w to a file changed on disk since read is refused once, as Save is (w again to overwrite), the rest of an X/'/w written and the refused named; Edit filters get a pane command's environment ($PARDES_MOUNT, $PARDES_9P, $PARDES_PID, $winid); an Edit with no commands runs beside one whose commands run unless it touches a file that one changes, refused busy (EBUSY) as is a second Edit with commands

An Edit's held write: < | > commands no longer block their 9P connection (answered like a held read, so a status read or a filter reading the session's own mount runs beside it), a Tflush or hang-up of the write kills the commands' process groups and changes nothing; e loads by Get's way (asked once, clean after, undo puts the name back); ~ in e r w f B; B checks every name first; an Edit that runs commands is a write of its own, refused up front with other lines; Edit's +Errors output keeps the keyboard where it was; X goes in pane order; a refused write open says its errno; the reference's Coming from acme rows say what Get file's undo, failure and directory refusal, Putall's answer, Zerox across Dump and Incl's directories now do

An undo step keeps no copy of the name: History keeps each name once, at the rename that ends it, and a step its generation, so typing allocates a snapshot and nothing more (follows prwqwwxt); a rename of one Zerox twin is logged for each twin

A refused Putall is answered once the other saves have landed; a bad Tab width is invalid (EINVAL), from a pane's exec too; Incl refuses a relative or missing directory and takes - only alone

Zerox twins survive a Dump and Restore: their text is dumped once, in the first, each other twin names it (twin_of), and Restore puts them back on one buffer with their dots

Undo after Get file or Edit's e puts the old name back with the old text and its clean state, so a Save or Putall after it writes nothing over the loaded file; a Get file that fails, or is asked about unsaved edits, renames nothing; Get file in a directory pane is refused with how to open it

ctl.getFile is the one load-under-a-name path: it reads first, then makes one undo step (whose snapshot now keeps the name and its saved state), renames and loads, and leaves the pane clean. Co-Authored-By: Claude Opus 5.5
