A --startup case in the perf harness times Pardes.init and the first frame for
each boot layout, with the same --json and --base shape as the others, so these
are a baseline rather than a one-off reading. The core boots and paints in
0.22 ms (tty) to 0.30 ms (classic): about one percent of what starting the
editor costs, and nothing to win.
The other 99% is one thing, found with perf record rather than guessed at.
Zig's start.main allocates through the Debug-mode DebugAllocator, which
captures a six-frame stack trace per allocation, and the first capture parses
and sorts the DWARF unwind tables of an 800 MB binary -- 22% of all samples sit
in mem.swap under that pdq sort. It is not the dynamic loader (25 us), not
static initializers (the binary has no .init_array), not paging (435 page
faults), and not lockStderr. std/start.zig:694 hardcodes DebugAllocator(.{}),
so there is no knob short of the build mode.
Controls that pin it down: a bare std.process.Init hello-world starts in 3 ms,
the ReleaseFast pardes-perf binary in 4 ms, /bin/true in 1 ms, and a Debug
pardes in 22 ms. The gui binary's 107 ms first run was cold page cache; warm it
matches the tty one.
So the conclusion recorded in features.txt is to leave it alone. Twenty-two
milliseconds is imperceptible for an editor, and the only lever is switching
the default build mode, which would multiply an already ten-minute build to
save eighteen milliseconds of startup.

The Tcreate that replaced acme's /new was a step away from the idiom dressed
up as a step toward it. A pane is named by a server-assigned serial, so the
create ignored the client's name: `mkdir /pane/foo` succeeded and left you
/pane/12. A mkdir that does not make the directory you named is worse than the
read-with-side-effect it replaced, and it broke in the shell workflow that
motivated the change. `create` is out of the declared features, so Tcreate is
EPERM again; Tremove stays, since `rm` to close a pane is unambiguously right.
/pane/new is now opened, not created: the open makes the pane, the read of
that fid answers its serial, two reads agree, and closing it leaves the pane.
That is /net/tcp/clone's mechanism (kernel/network/ip/devip.c, in ipopen),
not acme's, and the difference is deliberate. acme allocates during the walk
and lands inside the new window, so /dev/new/body works in one step, and it
can afford to list `new` because a Plan 9 directory read carries every entry's
stat and nothing walks. A kernel or FUSE mount walks and stats each name a
listing gave it, so allocate-on-walk would make a pane per `ls -l`. Allocating
on open keeps `new` listed -- a stat is not an open -- at the cost of the
one-step new/body. `new` stays unreachable from an editor path, because that
resolution serves Look hover previews.
The idiom pass behind it, read out of the Plan 9 tree at
~/05-genizah/principia-softwarica rather than recalled:
Rerror carries a string, not an errno (man 5 error: `ename[s]`), and acme
names every refusal. The five refusals pardes shares with acme now say what
they mean; the generic sites keep their bare errno rather than invent strings
acme does not have. body and tag declare DMAPPEND, which they had always
behaved as (acme(4): "always appended; the file offset is ignored"), checked
first against Linux's fs/9p, which never maps the bit. excl stays unset
everywhere, because acme sets DMEXCL on nothing. Blocking reads, per-object
addr scope and the readable pane ctl were already right. Real stat sizes and
qid versions stay: acme reports length 0 and version 0 for everything, and
Linux clients need better.
One bug fell out of it. open reset the addr range, so `echo '#0,#5' >addr;
cat addr` answered `0 0` and `cp addr dot` copied zeros. acme(4) makes the
contract explicit -- "a regular expression may be evaluated by writing it to
addr and reading it back" -- and acme gets away with resetting on the 0-to-1
open only because its clients hold the fid across both. A shell cannot: that
is two opens. The register is cleared by truncating it now.

Pty children are exec'd with their own TERM/COLORTERM/TERM_PROGRAM instead of
inheriting a .app launch's empty environment, and ttyTaken finally answers on
darwin — libproc walks the tty's foreground process group — so Escape reaches
the child and Exec stops believing every pane sits at its prompt. The
occupancy suite runs on both platforms now.
The workspace tag row moves into the native menu bar as a Builtins menu.
-Dworkspace-tag (default off for -Dplatform=macos, on everywhere else) drives
it, and Pardes.topBarHeight replaces the TOPBAR_H constant so the core stops
reserving the row.
The view pins every variable-font axis to the file's own default (Maple Mono
came up Thin otherwise), shapes ligatures, carries per-shape pointer cursors,
and draws the look-hover affordance as refracted glass. Tag rows fill edge to
edge, with the anchor box painted back on top of that fill and its mode glyph
centred on the same square. Theme accents re-saturated across the set.

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.

A swipe that was still moving when the fingers lifted stopped dead. The dial
next to it has thrown properly since pardes_rotate_end, and this is that same
curve on the scroll accumulator: velocity sampled between events off the
monotonic clock, weighted toward the newest sample because a flick is decided
by how the hand was moving when it left, and a fling that ramps up from zero
at the floor rather than switching on at it.
A coast stops at the end of a document rather than spinning its remaining
velocity against the edge, which is why spendScroll now reports whether the
pane moved and why paneAt is public. Only a step that delivered a press can
report an edge — the many steps between two rows cross nothing.
Nothing suppresses AppKit's own momentum, and nothing needs to: its momentum
events are ordinary pardes_scroll calls, every one of which cancels the coast
before spending its travel, so on a real trackpad the system takes the gesture
over about a frame after the lift and the tail it ends on is below the floor.
This is the path for devices AppKit does not fling for — and the only one a
script can reach, since NSEvent phases have no public constructor.
momentum.snap asserts both halves, which is why it needs the long scrollback:
a flick with no document left proves nothing. A slow swipe is byte-identical
after the release; a hard one coasts twenty-four rows further on its own, and
a finger back on the pad stops it there.

The builtin was gated on the SDL platform, so the macOS shell never registered
it and the setting had nowhere to land. macOS already had transparency, but
only the binary kind a theme decides — a theme with no background of its own
drops the ground and the blur shows through. WindowOpacity is the graded,
theme-independent version, and the window had no way to hear about it.
pardes_window_opacity reports the percentage and acknowledges the request in
one read, beside pardes_theme_bg: an SDL surface can arrive without an alpha
channel and has to be able to refuse, while an AppKit window always composites
per pixel, so there is nothing here to refuse and no rollback to perform.
The view then paints the rule shaders/ui.frag.glsl states for the SDL shell:
backgrounds — ground, cell and band fills, and the chrome rules over them —
take the alpha, glyph ink never does, and the block cursor is exempt because
it is foreground chrome that happens to be carried in a cell background. That
exemption is why the cursor joins the colour in the background run key; it can
no longer share a fill with the cells beside it.
Two things the harness was missing fall out of testing it: it never adopted
the theme background or the opacity, so a Theme or WindowOpacity in a script
moved the core and never reached a pixel. draw-opacity records both ends of
the alpha range, which is what makes the two-sided contract assertable —
60% reads 153..255, and 0% reads 0..255 with the ink still standing.

Tag text stopped living in the frame grid when the core moved the topbar, the
column bar and every pane tag into tag layers of their own; the grid keeps the
chrome and the physical grips. readFrame still read the grid alone, so every
capture recorded blank header rows and each script timed out waiting for text
that was on screen but not in the dump. Flatten the layers back over the grid
at one cell per column — the tty backend's spelling, which these goldens exist
to stay comparable with — and follow pardes_font_take to its size out-param.
The goldens were recorded before the column bar and before the tag gap, so
they are rerecorded here: the captures now agree column for column with what
the tty renderer paints today.
