The limit was 64 everywhere, which helix-golf's enumerate_and_align outgrows
(%s |\d+ makes 121 ranges). It is now memory.limits.selections, per platform,
and the counts that hold it are u16. The ranges stay inline in each Text, so a
pane grows by about 80 KiB on the desktop (three texts and the regex prompt's
snapshot); the Pane size budget in Terminal.zig moves from 128 to 160 KiB and
says why.

/log is now one ring (64 KiB, 4 KiB on the board) that records new, del,
rename and save, and a msg line for everything the editor says. An open
freezes it, so cat log shows what happened lately and ends; writing
follow to that same open makes reads past it wait for newer records, and
a follower the ring outran reads lost N first.
The message log keeps the pane's serial, not its reusable slot.
A test now fails when the tree serves a file /README never mentions; it
caught pty/status, now documented along with typing through pty/data.

The five arena buffers are zeroed globals instead of undefined fields, so a
Debug build keeps them in .bss rather than writing 160 MB of 0xAA filler
into every binary (Debug pardes 839 MB -> 246 MB).

In a Debug build memory.zig put each subsystem allocator (core, frame, lsp,
tree-sitter, image, PDF) under a DebugAllocator of its own, which is what
reports that subsystem's leaks and makes memory.deinit panic on one. Beneath
it, past the fixed buffer, was the allocator the shell passed in: init.gpa,
which std.process.Init already makes a DebugAllocator in Debug. Every block
that spilled out of a fixed buffer was tracked, checked and given stack
traces twice, and in a test both layers sat on std.testing.allocator.
A Debug build now puts the page allocator beneath the subsystem
DebugAllocators, so each allocation passes through exactly one. The shells'
own gpa is still std.process.Init's DebugAllocator for everything else, and
a release build is unchanged: the subsystems sit on the gpa, no
DebugAllocator anywhere.

The editor's loop was the only thing that could answer a 9P request, which
made the editor's own syscalls through a mount of its own tree -- a Look at
/mnt/9p/pardes/<me>/anything under a `9ns --mntgen` view, a Save into it --
requests only the blocked loop could serve. The name-based refusal that
followed (ownMountSuffix) and the in-process routing of a mount of oneself
(Client.sameSession) were patches over that, and both are gone, with the
mailbox that shipped every request to the editor's thread.
One rule replaces them, `pardes.turn`: the core is single-threaded, the
editor's thread has the turn by default and gives it up in two kinds of gap
-- while it waits for input and while a step of it is out in a host syscall
-- and a cloud9 connection task takes it in those gaps to answer. `out`
counts the steps that are out, from any thread: while one is, the core reads
consistently but that step still holds pointers into it, so a request that
would change a pane (a write, a truncation, an rmdir) is parked in the
engine and retried when the turn is next given up with nothing out, and the
editor's own wake waits for the count to reach zero. It is never a write of
its own that a step waits on out there -- writes come from a shell
performing a save between steps -- so a parked request is never the
syscall's own, and making a pane or rendering a screen need not park:
every yield sits before its step's mutation, so the layout and the surface
are whole under it. A changing request that queued effects is answered
once the editor has performed them (`echo Save > exec` returns with the
file written, as acme's `put` does), and it settles the way a step does,
because without that a /log reader waited for the user's next keystroke.
Every host syscall on a user path has to give the turn up, not fs.zig's
alone: the first end-to-end run hung in `inotify_add_watch` performing the
new pane's watch effect. PDFs and images are read whole at open, so no
draw goes out into the host. The core's allocator takes its fixed buffer
through the lock-free interface, since a connection task allocates while
the editor's thread is out in a syscall that allocates too. A Restore puts
the replacement in first and releases every task waiting on the old core.
cloud9 (pinned at eb1a104) parks an open, a truncating wstat, a clunk and a
remove on `again`, not only reads and writes, and answers a parked job
whose fid was clunked without asking the backend.
Verified: test/selfmount.py runs the editor under `9ns --mntgen` and
Looks at, reads and Saves its own tree through the mount; a unit test pins
that a change parks while the editor is out mid-step and lands when it
rests, while a read is answered in the window. 9P over the Unix socket
against a tty session, same machine, Debug builds: a read of /index 278us
-> 61us, a truncating body write 1184us -> 609us, exec Save 718us -> 583us;
the gesture benchmark is unchanged (geometric mean 0.997 over 53 cells).
Also from the reviews: a notice chip over an image or PDF pane was painted
out by the picture drawn after the cells, so pictures give up the rows; in
the GUI a tree-sitter context band painted over the chip, so body layers
are emitted first; a message is one row of printable text, its 256-byte
cut never leaves half a glyph, and one wider than its pane keeps its tail
(the file name, the reason) rather than its head.

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.

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.
