* Refuse a session's own mount, and paint notices as a tagline bandGabriel Schneider5 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Opening a path inside this editor's own 9P tree hung the session outright, and it is easy to do by accident: a file manager whose $EDITOR is pardes, or a Look at anything under /mnt/9p/pardes/<me>/. The realpath, the stat and the read all leave through the mount and come back as 9P requests only this editor's loop can answer, while that loop is blocked making them. The filesystem then stops answering anybody, which is what made it look frozen rather than slow. The answer has to come from the NAME, before any syscall, because the syscall is the thing that never returns: the listener notes the name it is posted under and `resolveOs` refuses a path containing `/pardes/<that name>/`, with `readLimit` refusing it too for anything that gets past resolution. Another session's mount stays perfectly usable, and `/n/self/...` is the way to reach your own tree -- the editor serves it from memory without leaving the process. Reproduced before and after: the 9P write that never returned now returns, the editor stays responsive, and it spends four CPU ticks doing it. The transient lines also now look like what they were modelled on. They carried the context band's bookkeeping -- one list, rows reserved the way sticky headers reserve them -- but still painted as ordinary body text, so a message read as a stray line at the bottom of the pane rather than as part of its chrome. They take the tagline font and the tagline's own colours now, verified on a running editor: the announcement lands with font_role=tagline. Two tests the features never had: a builtin announcing itself, reaching the notice list, being overridden by Msg's own text and silenced by Verbose; and the own-mount guard, including that a session with no listener refuses nothing.

* Plan 9 idiom for the control filesystem, and the regressions a624a56 leftGabriel Schneider5 days
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.zigGabriel Schneider5 days
| | | | | | | | | | | | | | | The served tree loses the self/ level: /index /ctl /new /log /screen /listeners /pane/<n>/... /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 <[email protected]>

* Refactor panes and filesystem; replace FUSE with 9PGabriel Schneider2026-09-07
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.
