plan9port: a one-button trackpad can execute and look
The core decides it at the press (mouse.emulateButton) and keeps it to the
release, whatever keys are let go between. Ctrl-click stays a definition,
and a program tracking the mouse still gets the plain click (Alt as its
meta, Super as nothing). The SDL, macOS and web shells now pass Super; the
macOS and web shells pass Alt on a click too. A terminal's mouse report has
no Super bit, so in a terminal only Alt-click is B2.

dissolve crossfades
- Track.launch: a move retargeted mid-way (Presentation.sync) starts at
the old move's speed along the new one's longest side (carriedLaunch,
Motion.easeFrom/speedFrom), so a second change during a slide bends the
motion instead of stopping it dead. The macOS track ABI grows the float
(pardes.h, 48 bytes; its reserved byte is named motion, as in Zig).
- A pane that slides, zooms or rises casts Lift's soft shadow at
sin(pi x progress) of its strength, on the other panes' bodies and
rails alone, under the same contrast ceiling, carried by its track.
- The GUI's PanelDissolve is a crossfade: the new cell drawn first, the
old one over it at 1 - progress, premultiplied, on the blending cell
pipeline for such groups (new cells now emitted before old ones, as the
old layers already came after the new). sRGB blend, not linear light
(documented). The tty keeps its per-cell swap.
Presentation.zig's and animation.zig's tests were not in any test root;
pardes.zig's test block now takes them in.
Tests: a retargeted move carries its speed and still lands exactly; a
moving pane's shadow is clipped off every tag, grip and its own body,
none at the start or the landing, most mid-way. GUI golden 18 changes by
the shadow (frame 6 of a slide). Gates as G6. Feel review:
.scratch/render/transitions/.

The user tried them live and wants them removed entirely: the builtins,
their levels, config keys and leader paths (tR, tg), their slots in the
built-in chain, their shaders (source and prebuilt), EffectCode paths, and
on macOS their scene flags (pardes.h), the Metal kernel's coordinate warps
and the Swift pointer mapping that mirrored them. Docs say so (decision 8
in docs/render-pipeline.md); config.md documents Crt's levels, Shader and
ShaderAnimation instead.
Shared files touched: macos.zig (flags). Not touched: pardes.zig,
Messages.zig, mouse.zig, gui.zig, detached/*.

resize columns from their grip
Every tag band (workspace, column, pane) is centred in its row, so text sits
at one baseline offset. Anchors are inset from the column rule by that same
margin, so they are square and the band frames them on the left, top and bottom;
the pane mark moves to stay centred. When the window is not a whole number of
cells, the bands, rules, spines and scroll thumbs at the right and bottom edges
run on through the leftover pixels.
A column grip dropped short of another column's place now moves the column's
left edge, with a dashed rail preview, sharing setColumnPairWidth with the
border drag. A release still on the grip changes nothing, and a pair too
narrow for two MINW columns is left alone.
PARDES_TEST_PAD adds leftover pixels to a test-mode window and capture.

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.

The body-layer context rules landed on a private TaglineMetrics.scale, which
never compiled: no macOS host built this shell when they were written. Expose
the physical-pixel thickness the way borderThickness/borderTop already expose
theirs, and paint the rule over the row's last pixel the way the SDL shell
does, so the two shells agree on the pixel rather than sitting one apart.

bugs go with them
Nine read-only scouts compared every host-side concern across `src/macos.zig`,
`src/tty/tty.zig`, `src/gui/gui.zig` and `src/detached/server.zig`. What they
found was not a style problem: each duplicated body had drifted, and in every
case the drift WAS a bug the users of that shell could see. So the fixes and
the deduplication are the same change.
**One PATH, adopted before the first fork.** LaunchServices hands a bundle
launchd's environment, whose `PATH` is `/usr/bin:/bin:/usr/sbin:/sbin`. Every
pty shell, `|` filter and language server the app forked inherited it, so
`yazi` in `/opt/homebrew/bin` was absent from a Dock launch and present in the
identical binary run from a terminal — the "it worked briefly" window was
simply the sessions started from a shell. `shell_bin.adoptSystemPath` composes
`/etc/paths` then `/etc/paths.d/*` in the order `path_helper` reads them,
deduplicating on first occurrence, and runs once at startup in all four native
hosts. It APPENDS: an entry already present keeps its position, so running it
over a real session cannot demote a mise shim behind `/usr/bin` and silently
change which `node` runs. A `PATH` that was configured is left byte-for-byte
alone; only one nobody configured is repaired. `prepareForFork` folds that
adoption together with the prompt-rc staging and the `BASH_SILENCE_DEPRECATION_WARNING`
setenv the five hand-copied prefork sites had between them — `server.zig` had
none of it, which is why every detached pane opened with Apple's zsh banner.
**The LSP protocol client never worked on macOS.** It opened its control
socket with `libc.SOCK.CLOEXEC`; Zig defines that constant for Linux and
Darwin answers `socketpair` with `EPROTONOSUPPORT`, so the call failed before
any fork, `ensure` returned `error.NoServer`, and every row in the spec table
— rust-analyzer, clangd, gopls — was unreachable in every macOS build. The
in-process ZLS backend kept answering, which is what made it read as "only Zig
is supported". It is a plain socket plus `fcntl(FD_CLOEXEC)` now, the route
`fuse.zig:943` and `nested.zig:95` already took for the same reason. The
snapshot suite that covered this path had never run natively on a Mac: the
harness targets defaulted to x86_64-linux.
**One LSP host worker.** `src/lsp_host.zig` is the snapshot, the worker body
and the job lifetime that `tty.zig` and `gui.zig` carried verbatim — `gui.zig`
said so in a comment — and that `macos.zig` did not carry at all: `lsp` and
`pipe` were absent from its `Host.VTable`, so the core answered its own empty
answer, `SPC l i` rendered a blank panel and a `|` filter silently did
nothing. All three shells share the module, and the AppKit host implements
both effects. Its status sink is now REGISTERED as well as defined, so
unsolicited server news reaches the message row instead of nowhere.
**The animation clock measures time.** `pardes_animation_tick` advanced one
scene frame per callback and published `frame_count / 60`, so scene time was a
count of callbacks rather than elapsed seconds — and `AppDelegate` re-armed
`asyncAfter(.now() + 0.016)` only after the previous frame's work had
finished, making the true period 16 ms plus all of it. Motion ran at about
three quarters of wall clock and unevenly. The tick now spends measured
monotonic time in whole `frame_ns` steps and banks the remainder, so a late
callback advances two frames instead of stretching one; `spendTickTime` is
that arithmetic as a pure function with its own tests and no display attached.
On macOS 14+ the animating run is one `CADisplayLink` phase-locked to vsync
rather than a chain rebuilt after every frame; macOS 13 keeps the old chain.
**Three more single definitions.** `panel_animation.paintOrder` is the
moving-then-opening-then-closing composite order as a rule the core applies
once in `Pardes.render` — `macos.zig` was re-sorting an already-sorted list.
`selection_pipe.Tasks` is the bounded in-flight pipe table `tty.zig` and
`gui.zig` each declared. `boxContains` was a fourth copy of the half-open cell
test and is now an alias of `Box.contains`.
**A filtered terminal stops asking libm per cell.** `Filter`'s legibility
stage called `RGB.contrast` for every painted cell, and that ends in
`std.math.pow` up to six times, re-deriving a ratio against a background that
had not moved; the existing memo cache covered the palette reduction beside it
and never this. The indexed path's input is a `u8`, so all 256 answers are
enumerated once per pass — after the default roles are fixed, before the first
cell is read — and what a cell names becomes an array index. Only truecolour
still reduces. ReleaseFast, 190x56, Tracy: recolour 3.09 ms -> 0.130 ms,
frame 3.37 ms -> 0.299 ms. The comptime luminance table is pinned to
`RGB.luminance` and `RGB.contrast` by exact-equality test over every channel
value and all 65 536 palette pairs, because the decision is a threshold
comparison where one ULP is a different colour. A `filterInit` Tracy zone
records the part that is still per-pass: 2.9 us warm against a 117 us pass,
which is the measurement that says not to cache it across frames.
Released as 0.0.2. `build.zig.zon` carries the version into `pardes --version`
and into the `Changelog` pane through `@embedFile`, so the entries above open a
`## 0.0.2` section and `## 0.0.1` closes with the tagline work of the parent
commit.
Two bugs here were mine, caught by review rather than by me: a double free in
the macOS pipe drain arm (`Msg.free` already owns the response) that segfaulted
the app on the first `|`, and a proposed `getRowAndCell` optimisation that
targeted 2 of 43 draw samples while the contrast math beside it took 12 — and
would not have compiled. The profile that justified it was a Debug build, which
`build.zig:1160` already documents as ~5x slower than release.
Native and -Dplatform=macos suites: 0 failures. All targets build with Tracy on
and off; the shipped release binary contains no `___tracy_emit_zone_begin`.
App reinstalled, signature verified, dmg regenerated, launched with 0 crash
reports; installed binaries verified byte-identical to a fresh build.

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.

The documentation had gone stale in the ordinary way -- claims that were true
when they were written and that nothing since had been obliged to re-read.
Some of them were load-bearing.
THE TUTOR. It still said there is no multi-cursor, that NextColor cycles three
themes, and that its practice blocks "are also run as unit tests (generated
from this file by tutor_gen)" -- a tool that appears nowhere in the tree, and
nothing anywhere parses a `# keys:` block. Left alone, that claim is what
makes the next wrong block survive.
Three of those blocks WERE wrong, and all three for one reason: since the
helix motion model landed, w/e/f/t SELECT the range they cross, so `i` after
one inserts at the SELECTION'S START. `w i Z esc` on "foo bar" gives
"Zfoo bar", not the "foo Zbar" the file promised. They were written against a
vim reading of the same keys. Every block in the file has now been run through
`zig build hxdiff` against the real core and matches byte for byte, and the
trap itself is written down in 3.3 rather than left to be rediscovered.
The tutor gains a PART 4 for everything added since it was written -- PDF
panes, the in-process ZLS backend, themes and fonts, the startup file -- and
PART 3 gains counts (and which keys ignore one), f/F/t/T, the whole g table
(bare `G` is a no-op; `ge` is the START of the last line), multiple cursors
and the s/S regex pair, `m`, `]`/`[`, `|`, insert mode, and all fifty leader
paths.
THE REST. design.typ's line table claimed 7,626 lines against a real 38,048,
and its rows did not sum to its own total; its Event/Effect boundary contract
-- the part a shell author writes against -- named four variants that do not
exist and omitted fourteen that do. lsp.md's probe count. config.md's
theme-name rules, which as written could not reach a zed theme at all.
helix-keys.md's Skipped section, holding five families that have since landed.
macos.md's menu bar, undocumented, along with sixteen other claims. web.md on
what the browser build can actually do.
SOURCE COMMENTS that had rotted alongside them: `tag_normal` is a space, not
the `•` its own comment describes; Wrap is ON by default, not off; a FontSel
row is SELECTED by n and RUN by Tab, not run by n; the SPC paths in lsp.zig
lost their `l` group prefix when the language group moved; and the
differential suites are 481 and 561 cases, not 360 and 440.
TWO THINGS FOUND BY DOCUMENTING THEM, both left standing and written down
rather than papered over. Typing `[^\n]` at an s/S prompt panics: the live
preview compiles every prefix, and `[^\` indexes an empty slice in mvzr's
parseCharSet. Both the tutor and a waiver recommended that pattern as the
workaround for `.` matching a newline; they now say what it costs and what
would make it sayable. And `Exec` is a builtin, so an `Exec` line in the
startup config types that command into a shell before the first frame -- the
tutor said nothing in that file is ever sent to one.
Nine adversarial reviews over two rounds, each with the hxdiff harness to
execute what it doubted. The second round exists because the first round's
fixes needed checking too, and it caught three regressions of my own -- one of
them a probe count I had "corrected" away from the truth.
Verified: unit-test, snap 87/87, hxdiff 481/0, hxparity 561/0, mupdf-check.
docs/design.pdf regenerated. The tutor's first seventeen lines are byte-
identical, which is what tutor.golden pins.

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.

Adds -Dplatform=macos, a fourth backend beside tty, gui and web. Zig keeps the
core, the ptys, every effect and the worker threads; Swift owns NSApplication,
the window, input translation, and drawing the cell grid with CoreText. They
meet at a hand-written C ABI in src/macos/pardes.h, built as a static library
the app links.
The ABI is src/web.zig's boundary with the wasm removed, because both hosts are
the same animal: someone else owns the clock, feeds events in through flat
functions, and reads one packed cell buffer out. The browser proved the shape.
The one divergence is that the browser has no processes and forwards every
effect to JavaScript, whereas forkpty is right here, so src/macos.zig performs
them — spawn, write, resize_pty, save_file, new_file, write_dump, open_link,
set_clipboard. lsp, pipe and watch are answered with nothing and marked; the
core already tolerates that, since the browser answers none of them either.
This deliberately inverts ghostty's split, which was studied first and is
written up in docs/ghostty-macos-notes.md. Ghostty hands Zig a bare NSView*,
installs its own CALayer and owns the frame clock; Swift never renders. Pardes
does the opposite because its frame is already a cell grid and CoreText draws
one natively — the alternative is a second hand-rolled glyph atlas, which is
what most of gui.zig's 4,300 lines already are. It would also have been written
blind: the Swift half cannot be compiled here.
What makes the scaffold verifiable rather than dead code is that the Zig half is
ordinary POSIX and builds and tests on Linux. Borrowing ghostty's best trick,
build.zig translate-C's the header into the test build and src/macos.zig asserts
every constant, struct layout, and exported function's arity and widths against
it. That guard earned its place immediately: pardes_scroll grew a cell
coordinate after the Swift view had been written against the older form.
Skipped, and named as the upgrade path in docs/macos.md: the Xcode project,
xcframework, lipo and codesigning ghostty needs. All four exist for
distribution; a dev build is a swiftc invocation and a directory with a plist.
The Swift app is a scaffold and says so — every uncertain API spelling carries
an UNVERIFIED marker, and no part of it has been compiled.
tty is unaffected: 75/75 snapshot scripts and both unit suites pass.
