A pane's message, its pending leader chord and a prompt waiting for input all
wanted the same row above the tagline. The prompt won it, the leader drew over
whatever was there on the right, and renderBodyLayer recomputed "is anything
down there" inline to reserve a single row. Three claimants, one row, and two
places deciding.
Pane.Notices is that decision in one place: a short ordered list of the lines
a pane is showing, rebuilt every frame by collectNotices from the state that
owns each one. The body layer reserves exactly notices.len rows, the way it
already reserves rows for sticky context headers, and the paint pass walks the
list and gives each line a row of its own, stacked upward from the tagline.
Nothing stores a second copy of the truth, so a line that goes away is simply
not added next frame and the rest close the gap. One notice lands on exactly
the row the message always had, and the prompt stays nearest the tagline so it
keeps its cursor.
Last also learned what to do when the jumplist is empty. It used to walk the
jumps and, finding nothing, do nothing at all -- which is the ordinary case
for a pane that opened beside this one and was never focused, such as the text
pane the bare tty layout puts under the shell. It now falls back to
neighbourPane: the next pane down the column, wrapping, and any other live
pane failing that. Alternating with the neighbour is what Last is for.

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.

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.

In raw tty mode Alt-n reached the child as a bare `n`: the ESC prefix was
dropped on the floor, and only on macOS. ghostty's encoder refuses the legacy
alt-esc prefix on a macOS build unless macos_option_as_alt says Option really
is Alt, and KeyEncodeOptions.fromTerminal cannot know that one — it says so in
a comment — so it defaults to false.
False is right for an app that lets macOS translate the chord and hands the
encoder the composed text. Every pardes shell decides the modifier itself and
hands the core the BASE key with the alt bit and no text at all, which
PardesView.keyDown and app.mjs both spell the same way, so by the time the
encoder runs there is nothing left to translate.
The unit suite has been catching this on macOS all along; it is only invisible
on Linux, where that branch does not compile in.

Empty marker on the last pre-Reload change. Keep the Reload experiment on reload (3801914), its first change on reload-start (200a1fc), and the unfinished performance investigation on reload-perf-wip.

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.
