* tag_layer.zig folds into Layer.zig, whose TagHit its two functions work onGabriel Schneider7 days
| | | | | | Two functions (sameCell, columnAt) on Layer.TagHit, 32 lines with their imports, used by edit.zig, mouse.zig and look.zig: they sit with the type now, called Layer.sameCell and Layer.columnAt. docs/design.typ names Layer.zig in its place.

* Mini.zig is mini.zig: a file of functions and no fields takes a namespace's ↵Gabriel Schneider7 days
| | | | | | | | lowercase name The naming the split agreed on, deferred until now; panes.mini is its name at its importers. File.zig keeps its alias line (const Mini = panes.mini) so the file another agent is working in changes by that line alone. The served sources list and docs/design.typ name the new file. No behaviour changes; test/perf.zig's two references change, and since the perf harness is keyed by its own text, its three baselines are recorded again (under other agents' builds, so a little slower).

Newcol now shares each such column's rows out again, and where a column has not the rows for every minimum there is no new column (Newcol: no space for a column: the panes' tags would not fit), as a size too small is refused. The sweep, 300 seeds, is the test; a user's drag or a tag grown by editing may still take a pane under, as before. Co-Authored-By: Claude Opus 5.5 <[email protected]>

A client asking for more now gets it, so a write up to 64 KiB less 24 is one Twrite, and round 24's no-newline cutoff (write_room, the negotiated msize less 24) follows: fs.py checks a 20000-byte ctl line from a 64 KiB client is taken whole. Each of the 16 connection slots holds its buffers at the larger size. Co-Authored-By: Claude Opus 5.5 <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | does, and a start with no terminal says so A name that did not exist yet failed resolveOs, so the launch fell through to starting an editor of its own, which on a pty with no controlling terminal (a detached session's) ended in a NoDevice error trace. A new name's directory is now resolved and the name kept: the launch reads pane/new and writes that path to the pane's name, so Save creates the file, and --wait waits on that pane (the git commit case). A standalone start whose /dev/tty will not open prints why and exits 1. fs.py covers both; the known-wrong line in docs/divergences.md goes. Co-Authored-By: Claude Opus 5.5 <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | remove, or a write to pane/new, must log no err The coordinator's reading of fs.md, now documented (slnyzzps): only a write or truncation logs its reason; a refused open (pane/new's and an OTRUNC one included), create or remove is its Rerror alone, and so is a write to pane/new. The oracle allowed an err or none for those, and required one for a refused pane/new open. Co-Authored-By: Claude Opus 5.5 <[email protected]>

| | | | | | | | | | | | | | | | | | | | | | | | write's unended tail is a line of its own Since round 24 (uwzuqzxp), a write to a lines file shorter than a Twrite holds is whole, as acme takes each write, so a look line written a byte a Twrite is as many looks as bytes, each missing with its own err. one_failure_rule still split the data on newlines whole, allowed one err, and failed the fixed smoke seed (20260929 step 607, size 20 6 written in bytes to look: 7 errs). served_lines models the tree's write (tree.zig) and has a self-check run at start.

Every run writes a replayable ops log; a failure is saved with its seed and step, shrunk by delta debugging over replays, and the run goes on in a fresh session. Teardown makes the fuzzer a subreaper and kills every process carrying the session's token. zig build monkey-9p -- --seed N --steps M | --replay F | --shrink F; a 150-step fixed-seed smoke run is part of fs-test.

| | | | | | | | | | | | | | | | is deleted, so it can be $EDITOR A launch inside a pane forwards its file to the session's look and returned at once, so fish's Ctrl-O (edit_command_buffer), git commit and crontab -e read their still-unedited file back and went on. With --wait, as acme's E against B and read the way plan9port's E reads acme's log, it finds the pane /index names the file by (the one already showing it, if open), follows /log on one connection with 'follow new', reads /index once more to catch a Del that came first, and then blocks with no deadline until that pane's del record: exit 0, or 1 when the connection ends with the session. The 9P client's one-shot requests keep their 2 s deadline; its new follow takes it for the setup only. Outside pardes nothing changes. --help, docs/fs.md, the README and the 9P skill say to set EDITOR='pardes --wait', which GIT_EDITOR follows. Tested in fs.py (it returns within 50 ms of the Del, a second -w waits on the same pane, one whose session is killed exits 1) and end to end: fish 4.8 in a detached session, echo hi, Ctrl-O, the waiting launch idle in poll, the line edited over 9P, Save, Del, and fish ran echo edited.

* | Only a write logs an err: a refused open or truncation, create or remove, or ↵Gabriel Schneider7 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.

| | | | | | | | | | | | | | | | quoting what was written, and a refused placement is the look's only failure A look at utf8txt:#3 from a terminal searched for utf8txt, missed, then found the terminal no text to address: two errs for one write. It is now looked for whole, as zzq:2 already was, so every form's miss reads no match for "<as written>". A look whose new pane was refused a place went on to settle its line in the pane it stayed on and logged has no line N after the placement failure; it now stops there.

| | | | | | | | | | | | | | | | now say, not at the close Round 24's no-newline rule (uwzuqzxp) already covers name, a lines file; the 9P monkey's close_runs_only_line_files repros were from a binary before it.

| | | | | | | | | | | | | | | | draws them Its reference list compared \xe4\xb8 with vaxis's own gwidth, which counts the pair one cell; since qsltkuom each invalid byte is a cell, one U+FFFD each, as surface.zig draws it, so the pair is two.

* | An invalid byte in a grapheme is one cell, and never reaches vaxis's widthGabriel Schneider7 days
| | | | | | | | | | | | uucode joins a stray lead byte (as U+FFFD) to a following e and combining mark into one grapheme; vaxis's gwidth then counts back the replacement rune's three bytes over the one byte it stood for and overflows (gwidth.zig:62), panicking the next frame after a write of \xee e \xcc\x81 to xdata (the 9P monkey's crash-b2417c49). graphemeDisplayWidth now gives each invalid byte one cell, as surface.zig draws it, and measures the valid runs between alone.

| | | | | | | | | | | | | | | | first step A 9P write served before a detached host's first pump holds its batch stamped at time 0, so nextWake said to wake at 20 ms while advance, seeing the clock for the first time, set stepped_ns days later and counted due - stepped_ns back past zero: an integer-overflow panic. It was what the 64 KiB msize trial hit in fs-test (restore detached space, the connection closing at the first write's clunk), a race any msize can lose. A batch's wake is now never before the next frame. Co-Authored-By: Claude Opus 5.5 <[email protected]>

| | | | | | | | | | | | | | | | range up to 256 runes spelled out mvzr's classes hold bytes, and it refused a multibyte member as a bad expression. Rewriting the class before compiling, as ^a|^b already is, needs no mvzr patch; runes that differ only in their last byte go as one alternative (\xc3[\xa0-\xbf] for [à-ÿ]) so a 256-rune range fits the 512-operation limit, which counts the pattern as rewritten.

An address, a limit and the mark flag are nothing drawn; their writes no longer ask for a frame. Clunk after an addr write: 0.518 -> 0.015 ms (Debug tty, fs.py client).
