Focus gives the keyboard only, reads empty while a header has it, and sits in the root listing's natural place

2026-10-01T03:12:14Z

A write to /focus leaves a folded pane folded, as rio keeps current apart from unhide; while a column or workspace tag has the keyboard no pane does, so /focus reads empty and every pane's ctl says notcurrent (an empty read also no longer answers stale staged bytes). focus, ctl and commands now list after status, and the discovery test checks the root as a set rather than by position.

A root focus file names the pane with the keyboard and moves it; a pane's ctl says whether it is current

2026-10-01T03:12:14Z

Scripts had no way to ask which pane has the keyboard or to give it one. rio answers both through a window's wctl: its read ends with current or notcurrent, and a write of current takes the keyboard (rio(4)). A pane's ctl line now ends the same way, and since there is one keyboard for the whole tree, /focus reads the focused pane's serial and takes a serial to move the keyboard there, off any header that had it; a serial no pane has fails with "no such window". fs-bench's stale readdir check is fixed too.

File the tag code into tagline.zig and draw tags beside bodies

2026-10-01T03:12:14Z

With tags reduced to Texts, what is left of them is the computed prefix, the default and saved tails, entering and leaving a tag and the headers: that goes to tagline.zig, as acme keeps the tag half of a window in wind.c. Tag and header drawing moves next to body drawing in body_layer.zig, and the tag hit helpers go to tag_layer.zig with the Hit they read, where sameCell now also tells the lines of a taller tag apart. The docs describe the tag as a Text. Co-Authored-By: Claude Opus 5.5

Give a pane's body its own Text holding the cursor, selections, mode and undo

2026-10-01T03:12:14Z

acme keeps what edits a text in its Text (dat.h:171-190) and the window holds a body and a tag of that type. The cursor, the selections, the modal state and the edit-buffer undo move off Pane into Text.zig, Pane holds them as its body, and the edit and normal-mode operations take the Text they edit. Nothing changes in behaviour; this is the step that lets the tag become a second Text. Co-Authored-By: Claude Opus 5.5

Keep a pane's filesystem state on the Pane instead of a slot-indexed table

2026-10-01T03:12:14Z

addr, limit, the event queue and its readers, pty/data's queue, a waiting run and the /log announcement flag lived in p.fs.panes[slot], reset when the pane went; a reused slot is how the bug class came in. acme keeps the same state on its Window (editors/acme/dat.h:226-266), so now Pane.fs holds it: announced, retired (noteRetire, which still answers a waiting run and drops the listener count first) and freed with the pane itself.

Plan 9 idiom for the control filesystem, and the regressions a624a56 left

2026-10-01T03:12:14Z

The 9P tree stops being a command language wearing a filesystem. /new created a pane as a side effect of a *read*; it is now Tcreate in /pane, with Tremove to close, which cloud9's engine has always supported and the editor never declared: tree.zig now says `features = .{ .create = true, .remove = true }`. Eleven pane ctl verbs become files that can be read as well as written -- dot, limit, dirty, mark, scroll, look, exec -- leaving ctl with `get`, the one verb no file would say better. Root /ctl splits into a read-only /status and the /look and /exec files whose write IS the click. stat carries real sizes where it used to answer 0, and qid versions track a pane's revision, so a client can poll for change without re-reading the body. Commit a624a56 moved raw-tty keys to an early-return branch that knew only Ctrl-B and bare Escape, and in the same edit deleted the paste branch below it. That cost Shift-Escape (the unconditional way out of tty mode) and both paste chords: Ctrl-V and Ctrl-Shift-V reached the child as keystrokes, so an agent CLI running in a pane took Ctrl-V for its image-paste binding and answered "No image found in clipboard". Both are restored, with tests. Nested detection was not subtly broken but deleted: 60367d8 removed nested.zig's process-ancestry walk and left "am I inside pardes" derived from PARDES_FORWARD_LOOK, which read "0" both for --nested and for "the listener did not come up". PARDES_PID now answers that question on its own, checked with kill(pid, 0); PARDES_9P and PARDES_PANE answer how to reach it; the flag is gone. The posted-9P registry also self-heals now -- a session that aborts cannot unlink its own socket, so posting sweeps entries whose target refuses a connection, symlinks only and on a definite ECONNREFUSED only. Elsewhere: tty scrolling is sticky-bottom, following new output only from the last row, with typing and entering raw mode snapping back to live; the boot layouts are a Boot enum instead of a chain of ifs, and the bare tty startup (Boot.tty, which main.zig names) opens an empty text pane under the shell while tests keep Boot.tty_shell; builtins announce themselves on the message row under a Verbose setting that is on by default; Config prints each setting the way you would type it back, so WindowOpacity 70 rather than "WindowOpacity: 70%"; LocationsConfig opens its window only when called bare; every tagline puts the word that closes the thing last, and a column now outlives its panes -- closing the last one leaves an empty pane, and only Delcol, newly on the column tagline, takes the column away.

Flatten the 9P control tree and move it out of fs.zig

2026-10-01T03:12:14Z

The served tree loses the self/ level: /index /ctl /new /log /screen /listeners /pane//... /os, with /src only in -Dembed-sources=true builds (default off, on for esp32p4). ctl speaks the editor's own language with two lowercase verbs, look TEXT and exec TEXT, plus acme's addr verbs; the new/ factory directory becomes one clone file; cons is gone (exec Msg); name and sel are files; stats report real lengths, modes and mtimes; /log streams pane new/del/rename/save events. The tree code lives in src/ninep/ (tree, pane, ctl, addr, pty, events, screen, sources); fs.zig keeps host access, mounts, resolution and find/grep. Same engine and transports. README (fs-help.txt) and docs rewritten; tests updated and extended. Co-Authored-By: Claude Fable 5.1

Refactor panes and filesystem; replace FUSE with 9P

2026-09-07T16:59:12Z

Consolidate pane, layout, memory and host code. Serve 9P by default over Unix sockets, with runtime mounts and optional TCP/QUIC transports. Remove FUSE and obsolete proof-of-concept examples. Fix highlighting and terminal-history performance, expand differential and stress-test infrastructure, sort navigation results while preserving the next occurrence, add syntax-colored Braille minimaps, remove SPC-k, and document 9P interaction as a repository skill.
