With no Shell set, pardes ran fish, which a box may not have and a user
may not use. The default is now the user's login shell ($SHELL), else
/bin/sh; an explicit Shell still overrides it. The tests pin their own
shell (snapshots bash, the python suites /bin/sh or bash) and pass with
SHELL unset; the Config report and docs say where the default comes from.

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.

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.

effects that compile
Three things this shell had its own copy of, and in each case the fix is that
it stops having one.
**The tagline band.** A pane tag draws at `gui_tagline_font_percent` of the
body face and the band it sits on shrinks with it, while the grid row stays
body-sized — so something has to decide where the shorter band sits in the
taller row. This shell decided by centring, always, which is precisely the case
`config.gui_topbar_pane_border_px` exists to prevent: the topbar's unused
half-band meets the first pane tag's unused half-band and the window background
shows through the seam. The strip is as wide as the bands are short — on a
20-pixel cell, 4 physical pixels at the default 82%, 10 at 50%, 14 at 30% — so
it grew as the tagline face shrank and read as "the tagline is wrong on the mac"
rather than as one missing rule. The rule is `pardes.taglineBandOffset` in the
core now and both pixel hosts call it: row zero bottom-aligned, the first
pane-tag row top-aligned, the two joined by `gui_topbar_pane_border_px` in the
theme's scrollbar-track colour, every row between centred, and a `Tagbottom`
band on the final row flush with the window edge — with the sub-cell strip
beneath it painted in that band's own colour, because the core grid holds only
whole cells and a window is any height it likes. `pardes_tagline_band_offset`,
`pardes_topbar_pane_border_px` and `pardes_topbar_pane_border_rgb` carry it over
the C ABI as PHYSICAL pixels: the host multiplies its points by the backing
scale going in and divides coming out, which is the snapping `Metrics` already
does for the cell, and is what keeps a one-pixel rule one pixel instead of a
two-pixel smear.
**The watch.** `file_watch.zig` was one mark/reconcile transaction over
`inotify`, so the tty shell, the SDL window and the detached daemon all watched
nothing off Linux: an edit made outside pardes never reached the pane, and a PDF
replaced on disk kept rendering the old inode. It is the same transaction over
two kernels now — `init`, `wait`, `stop`, `drain`, `markDir` and `unmarkDir` are
still the whole of it, and the hosts wait on a kqueue and poll it exactly as
they did the old descriptor. A macOS mark is TWO filters, because a kqueue
directory filter reports its entries changing and never a write to a file
already inside it: the parent mark follows rename-over saves, `markFile` catches
in-place writes, and `remarkFile` re-arms the file filter once a rename has moved
the inode. That is the same pair the AppKit host's DispatchSources already used
for the same reason. Directory marks are deduplicated here by device and inode,
because each `EVFILT_VNODE` filter needs a descriptor of its own and inotify did
that deduplication itself; `stop` and `drain` wake through the one `EVFILT_USER`
filter, since a kqueue cannot simply be read the way an inotify descriptor can.
**The effects.** The three `crt.ci.metal` entry points are
`extern "C" [[stitchable]]`. `CIKernel.kernels(withMetalString:)` compiles that
source at runtime, looks for stitchable functions, and rejects the WHOLE source
with "cannot find a valid stitchable Metal function in the source" when it finds
none — so `ScenePostprocessor.init?` returned nil and every scene effect and
panel transition silently degraded to the plain CoreText draw. The
`effect_sources.zig` test pins the exact spelling of all three, and
`draw-effect` in the e2e suite catches the degradation rather than the spelling.
Beside them, the offscreen harness owes the core a PRESENTATION. Its window is
borderless and never ordered front, so AppKit runs no display cycle and
`pardes_frame_presented` — whose only caller is `draw(_:)` — never fired. The
core holds pointer gestures inert while a layout mutation has not reached a
backend, which for an unpresenting harness is the rest of the script: the first
pane a script opened silently killed every later click, drag and Look. So
`readFrame` presents what it just rendered, into a bitmap nobody reads.
`PARDES_CHROME` also looks under `/Applications`, where a browser's executable
lives inside an application bundle and never on `PATH`. The macOS goldens are
regenerated; docs/macos.md, config.md, detached.md, web.md and the design PDF
follow.

Three changes that all turned out to be the same shape -- a feature that
worked in one direction, or for one pane kind, and quietly did not in the
others.
CLIPBOARD. Every register write emitted set_clipboard, so deleting one
character threw away whatever the desktop was holding; multi-cursor yank took
the join's early return and emitted nothing at all, so the same key reached
the clipboard on one cursor and not on two. Nothing could READ the clipboard:
the SDL shell had no SDL_GetClipboardText anywhere in it, and the tty shell
never asked for OSC 52, so `p` from another application was dead in both.
Now it is helix's split. y/d/c/p/P/R and the acme chords are the DEFAULT
REGISTER and nothing else; the system clipboard is five words on helix's own
letters -- SPC y, SPC Y, SPC p, SPC P, SPC R -- spelled as builtins so they
land in Help and are executable like every other verb. The one exception is
the tag `y` chord, which still mirrors out because a tag is always insert, so
SPC cannot be pressed there, and copying the path out is the whole point of
the chord.
Reading is a new read_clipboard effect answered by an ordinary Event.paste, so
the round trip is honest about being one: SDL and NSPasteboard answer inside
the same drain, the browser answers a promise, and a terminal answers over
OSC 52 or -- far more often -- refuses. A refused read is a paste that does
not happen, and the request dies at the next keystroke rather than landing
minutes late in whatever pane is focused by then.
The tty shell also enables BRACKETED PASTE now and coalesces
paste_start..paste_end into one event. Before this a paste arrived as a flood
of individual key presses: plausible in insert mode, and in normal mode every
pasted character ran as a command.
n/N. They stepped the armed results buffer and immediately Looked each row, so
you could not walk past a hit without opening it. They are a MOTION now:
select the next look-able text, open nothing, and let Enter decide. What they
step is the largest whitespace-delimited run look.resolve can act on
(look.lookableSpan, wrapper punctuation peeled), over a RING of panes -- every
pane that has performed a look, most recent first, then the output buffers
that have not, newest first, and only if both are empty the pane in front of
you. N is the exact inverse of n, computed rather than remembered: both
directions ask the same question about the same spans and compare against the
column the walk parks on, so x presses one way and x back land exactly where
you started, pane boundaries and the ring's seam included.
A ring rather than a list with two ends because a shell's cursor sits at the
prompt, below everything it has printed, so a walk that could not come round
would have nowhere to go on the very first press -- which is the case n/N were
written for.
One motion everywhere, no pane-kind or buffer-kind special case. The only
thing a buffer may change is the GRAIN of what a step selects, and it does it
with one flag rather than a branch: output_pane.Traits.commands (renamed from
`executes`, which named one reader's behaviour rather than the fact) makes a
row select WHOLE, because a ThemeSel line is a word to run and has no path
inside it to pick out. `]d`/`[d` are not n/N -- they are helix's diagnostic
motions, their job is to ARRIVE, and they still reach searchStep.
THE TTY PROMPT. Leaving raw tty blanked the prompt row, and the command you
had typed at that prompt shares the row, so it went too -- a shell out of tty
read as output only. OSC 133 marks the row CELL by cell, so the two are
separable: config.tty_blank = .prompt cuts the prompt's own columns and leaves
the command, left-hugged at column 0 in line with the output under it rather
than in a bay of blanks. .prompt_and_input is the old behaviour, kept.
Because the row is now something you can put a cursor in, enterTty adds the
hidden prompt width back before asking ghostty to walk the shell's own cursor
to it -- the modal column on a cut row is short by exactly that much.
Verified: unit-test 186/186 (nine new), snap 87/87 (new ttyprompt.snap),
hxdiff 481 and hxparity 561 with 0 mismatches, tty and gui both build. And
against the real binaries rather than the harness: in a pty, SPC y emits OSC
52 carrying exactly the selection while plain y emits nothing, SPC p issues
the read and pastes the reply, and a bracketed paste of "dd..." inserts text
instead of deleting two lines. In a real SDL window, SPC y then SPC p round
trips through the system clipboard while the default register holds different
text. Setting tty_blank back to .prompt_and_input reproduces all 86 old
goldens byte for byte.

The AppKit shell now draws what the core renders, follows the theme without a
relaunch, and builds into something you can hand to someone.
- Pixel attachments. Surface.images was dropped on the floor here, so a PDF
pane showed nothing at all: native_images is now set, pardes_image_s carries
the geometry the core already clipped, and PardesView keeps one CGImage per
(serial, page, revision) so scrolling costs a draw and not a decode. Image
panes get real pixels instead of the petscii fallback.
- Themes take hold live. pardes_tick never advanced the chrome animation, so
every tagline kept the previous theme's colours until the next launch and
the 16 ms re-pump spun for the rest of the session. pardes_theme_bg retires
the hand-agreed #121212 and drives the window background and the titlebar
appearance; a theme with no background of its own now gets a transparent
window over an NSVisualEffectView.
- The cell snaps to whole DEVICE pixels rather than whole points. Monaco
advances 8.4014pt at 14, so ceiling to 9 spaced every column 7.1% wider than
the face was drawn for.
- The dial is one notch per 10 degrees instead of 20, and a release keeps
turning in proportion to how hard it was thrown -- ramping up from zero at
the floor, so a slow twist coasts not a little but not at all.
- A file dropped on the grid is a click plus Look, so it opens beside the pane
it was dropped on. No drop concept was added to the core.
- The titlebar follows the focused pane: proxy icon, filename, and the dirty
dot. File.saved_revision is the watermark that last one needed.
- Config (SPC f c) prints the resolved startup config path.
- build.zig assembles, signs and packages the bundle itself; build-app.sh is
gone. -Dmacos-identity= takes a Developer ID, macos-dmg makes the image, and
the icon is Glenda.
