Makes weather render on macOS and iOS the way it does on the fixed Windows renderer and in the browser. Needs the core PR for bold text and :root padding.

Both targets

  • Scale the app's gea.designWidth to the window or screen, and follow viewport changes. On macOS the value never reached the bundle: an undefined variable produced <real>00</real> in Info.plist.
  • CSS line-height is honoured in text measurement; glyphs overflow a short line box instead of being clipped.
  • gea_host_measure_text_with_style: font weight is measured and painted, with a synthetic bold (Chrome's stroke amount) when the font has no heavier face.
  • A styled <button> renders its children at their layout positions instead of one flattened title, so chips keep their temperature and the pills show their labels.
  • overflow-x rails are clipped plain views positioned by the engine's scroll_x. Only overflow-y auto/scroll becomes a native scroll view. On iOS this also fixes rails moving twice as far as they scroll.
  • white-space: nowrap + text-overflow: ellipsis, z-index stacking, and text-colour alpha.

macOS: the wheel and a sideways drag pan rails, and a drag doesn't click; object-fit: cover fills instead of contain. The NSTextFieldCell's 2pt side inset is left out of measurement, so labels match the browser's widths. Note: this narrows text boxes in every macOS app.
iOS: real fetch backend and WiFi driver; percent and pill border-radius; a zero-size box hides its subtree only when it clips; layout dump.

Verified: built and compared against the Chrome reference on macOS (default and resized window) and on an iPhone 16 Pro simulator.
Known: test/run-ios-native-view-renderer-source-test.sh asserts the old button-title design and needs updating. It was not run.

Both build scripts walk the node_modules chain to find @geastack/core,
@geastack/compiler and friends. In a collection checkout the packages are
siblings that nothing links, so the walk finds nothing and the build stops
before it starts. Fall back to the collection layout when the walk comes back
empty; an app that installs @geastack/apple resolves them normally and never
reaches the fallback.

iOS had no networking at all. core's host/host/fetch.cpp has three arms --
browser, ESP-IDF, and a desktop fallback that calls two weak hooks and returns
whatever they produce, which is nothing by default. Android, macOS and
Raspberry Pi OS each strong-override that seam; iOS never did, so every fetch
resolved to an empty response and wifi().connected() answered false forever. An
app that gates its requests on the link state therefore sat on its placeholders
and never recovered.

ios_network.mm is the macOS backend with one substitution. NSURLSession and the
two hook overrides carry over verbatim -- they are pure Foundation -- while the
WiFi driver swaps SystemConfiguration's dynamic store, which is macOS-only, for
an NWPathMonitor writing an atomic flag. The flag starts optimistic, matching
what Android does before its bridge has answered, so apps are not told they are
offline during the first frames while the first path update is still in flight.

Both Apple shells assumed their layout space was already the right size: macOS
passed no ratio at all and iOS pinned it to 1, on the grounds that UIKit renders
retina through contentScaleFactor and an extra scale would blow up px lengths
relative to unitless ones. That reasoning holds for an app that mixes the two,
but it leaves an app authored entirely in px at the mercy of whatever screen it
opens on -- drawn for a 273pt panel, it occupies a corner of a 393pt iPhone and
a fraction of a desktop window.

gea.designWidth is that app saying its px are the whole layout. Each shell now
divides its real width by the declared one and hands the result to
Application::init, which scales the design to fit. It rides Info.plist on both
platforms: the width belongs to the bundled app, and every app gets its own
bundle. macos.json stays what it was, window geometry.

Apps that declare nothing keep exactly what they had -- ratio 1 on iOS, the
build's configured ratio on macOS.

The frame loop forced the root node's width and height to the new window size,
which is enough to relayout the tree but not to tell the engine anything. vw/vh
lengths and @media conditions resolve against the viewport metrics, and those
were only ever set at launch -- so a window that started at one size kept
evaluating its breakpoints against that size no matter how far it was dragged.

Set them from the frame loop whenever the size actually changes, mirroring what
the Android shell does on a surface change. setViewportMetrics recomputes class
styles, so the guard matters: without it every frame would pay for a full
restyle.

A style colour is an opaque packed pixel — RGB565 has no alpha channel, so the
style system keeps one representation for every board and carries the CSS alpha
in a companion field (bg_alpha, text_alpha, border_alpha, …). iOS unpacked the
pixel's own alpha byte, which is always 255 by construction, and passed
alpha:1.0 regardless; it read the companion fields nowhere.

Every translucent surface therefore painted solid. Weather's city chips are
rgba(255, 255, 255, 0.11) with near-white labels, so they came out as opaque
white blocks with invisible text, and its rgba muted labels lost their fade.

macOS already fixed exactly this, down to a comment naming these chips
(createStyleCGColor in macos_renderer.mm); Android folds the alpha into the ARGB
int at the JNI boundary. This is that fix, ported: the converter takes the alpha
as an argument and each call site passes the field that belongs to it. There
were two copies of the lossy converter, so both needed it.

Deliberately not touched: view.alpha, which is element opacity and would fade
the labels sitting on a translucent chip along with it; and the root background,
which is the bottom-most layer of the window and has nothing behind it to blend
with.

Application::init published the viewport once at launch and nothing ever did
again, so vw/vh lengths and @media conditions were frozen at the launch size:
rotation, a split view or a safe-area change reflowed nothing. macOS grew the
same fix recently; this is its iOS half, guarded so the recompute only runs when
the size actually changes.

It also fixes something that looks unrelated. `.screen`'s
`padding: var(--safe-top) var(--safe-x) var(--safe-bottom)` resolved to 0 on
iOS, so weather's content sat flush against the left edge, and it stayed 0 for
every one of the 99 frames I dumped. The padding is not applied by either Apple
renderer -- the engine bakes it into the children's positions -- so a 0 there is
a value that never resolved, not a frame the reconciler got wrong. The custom
properties are declared on :root, which binds to the mounted root, and the
ancestor chain from .screen reaches it, so the lookup should have found them.

What differs is how many style passes each shell runs. setViewportMetrics ends
in recomputeAllClassStyles, so macOS gets a second pass on its first frame and
resolves the var then; iOS only ever had the first one. That first pass is where
the real bug lives: a var() length that misses is cached as a negative result
against every node the lookup walked, and the two calls that later WRITE a
custom property invalidate no cache. Publishing the viewport gives iOS the
second pass and the value lands, but it heals the symptom -- the engine should
not need a second pass to get this right, and macOS is only correct today by the
same accident.

GEA_IOS_LAYOUT_DUMP prints the engine's node boxes beside the UIViews they
became. iOS had no introspection at all; every finding above came out of it.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
isScrollableNode only ever asked whether content was taller than its box, so a
box that scrolls sideways never became a scroll view — while view_reconciler
still gave it clipsToBounds from the same overflow style. The result was the
worst of both: a rail that is clipped and cannot be scrolled. Weather has three
of them (the city chips, the hourly rail, the daily rail) and every one was a
dead box with its overflow permanently out of reach.

The engine already models this fully — overflow_x and overflow_y are separate,
scroll_content_width sits beside scroll_content_height, and Tree has
scrollLeft/setScrollLeft. Only iOS ignored half of it. Detection now follows the
engine's own idiom (the aggregate gates, the per-axis field decides), which also
makes the vertical case stricter: a box that scrolls only sideways no longer
counts as a vertical scroller because its content happens to be tall.

The container carries the axis and reads its offset, content size, bounce
direction and tree write-back from it. Content grows only along the scrolling
axis; letting it grow on both gave UIScrollView slack in a direction the app
never asked to scroll. Telemetry follows the same axis — it reported a constant
zero for a horizontal rail before, which would have made this harder to see, not
easier.

Verified through GEA_IOS_LAYOUT_DUMP: the city rail is 345pt wide around 502pt
of content and the hourly rail 345 around 456, both axis=x with the matching
157pt and 111pt of travel. Before, neither was a scroll view at all.

Both targets implemented only gea_host_measure_text, the variant with no
line-height parameter. The engine prefers the line-height-aware hook and only
falls back to that one, so every text node was measured at the font's own
leading and CSS line-height was silently ignored on macOS and iOS alike.

Weather's forecast labels are 10px/1.1: they measured 22px instead of 17,
which made each hour cell 90px instead of 80 and overflowed the forecast box.
Implement the line-height variant instead -- it serves both call sites, since
a caller with no line-height passes 0 -- and pin min == max line height so the
reported box is lines * line-height, the CSS line box.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Measuring with the CSS line box is correct, but applying it when drawing is
not: a line-height under the font's natural leading makes AppKit and UIKit
shrink the drawn line, and the descenders fall outside it. Weather lost the
bottom row of pixels from every label the moment measurement became accurate.

CSS does the opposite -- the glyphs overflow the line box and still paint --
so drawing now only ever GROWS the line, and the macOS text field is given the
extra leading it needs, centred on the box the engine allocated. The layout
position does not move; only the painting surface does.

Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
GEA_MACOS_LAYOUT_DUMP printed geometry only, so a wrong box could not be
attributed to the declaration that produced it. Add the node's parent, class
and the fields layout actually reads -- width, width%, min/max width, flex,
flex-basis, flex-shrink, display, flex-direction, white-space, font-size,
line-height and padding -- matching what GEA_IOS_LAYOUT_DUMP already reports.

Every diagnosis in this round came out of these columns.

build-macos.sh asked `apps inspect` for the design width with
`--project "$GEA_APPS_ROOT"`, a variable nothing defines. Under
`set -euo pipefail` the pipeline failed, `|| echo 0` appended a second 0, the
result "00" passed the `!= "0"` check, and Info.plist got
`<real>00</real>`. The runtime read that as no design width, so weather
fell back to the build's default ratio: right at the 546px default window by
accident, and never rescaled when the window was resized.

Run `apps inspect` without the stray flag, let each step fail soft, fall back
to the app's package.json `gea.designWidth` as build-windows.mjs does, and
compare the result as a number.

The Windows renderer was just brought in line with the browser for the weather
example; macOS still diverged on most of the same points. Side by side with a
Chrome rendering of the same stylesheet at the same 273 CSS px width, these
were the differences, each now handled as win32 handles it:

- Styled buttons. A <button> with a CSS background (weather's chips and
  pills) was a native NSButton showing its first text child as one title in
  the button's own font: "Cities" painted at the 7px button size and the city
  chips lost their temperature. Such a button is now a plain box
  (GeaStyledButtonView) whose children are laid out and painted like any
  other box's; a press anywhere inside targets the button, and clicks go only
  through the root click bridge.
- Sideways rails. The renderer tested the combined `overflow == 2`, so the
  city, hour and day rails became vertical NSScrollViews whose document was
  only as wide as the rail: clipped and unscrollable. Only `overflow-y`
  auto/scroll becomes an NSScrollView now; a rail is a clipped plain view whose
  children the engine places by its own scroll_x. A wheel or trackpad over a
  rail pans it (MacosRenderer::scrollWheel), and a mostly sideways drag past
  6 CSS px pans it and ends without a click.
- Overflow clipping follows `overflow != 0`, so those rails still clip.
- Font weight. Only the line-height measure hook existed and fontForId took
  no weight. gea_host_measure_text_with_style is implemented, weight is part
  of the font cache key, and a CSS bold with no matching face (weather ships
  only Oswald Regular) is synthesized with a stroke of Chrome's pen size.
- Text alpha. rgb565ToNSColor was always opaque, so `--muted` text painted
  full white. Text colours now carry the node's text_alpha.
- white-space: nowrap and text-overflow: ellipsis are honoured: one line,
  tail cut with an ellipsis or clipped, without AppKit's letter tightening, so
  a chip reads "San Fran…" as in Chrome.
- z-index. Sibling views are stable-sorted by z-index, so the hero art sits
  under the city name instead of over it.
- object-fit: cover was mapped to a proportional fit, i.e. contain; it is now
  drawn by an aspect-fill layer clipped to the view.
- A line-height taller than the font's natural line centres the glyph run in
  the line box instead of putting all the leading above it.
- NSTextFieldCell insets its text 2pt from each side, so every label measured
  4pt wider than the browser's. Measurement leaves the inset out and each
  label field is widened by it; chip and pill widths now match Chrome to the
  pixel. This narrows text boxes in every macOS app, not just weather.

Checked by building weather, comparing screenshots against the Chrome
reference at the default and a resized window, and exercising the wheel, the
rail drag and chip clicks.

The canvas and the mounted root were sized once, at launch, and the display
view was placed in the safe area only then. A later viewport change
republished the metrics but left the canvas width -- what layout px are
mapped onto the screen with -- and the root box at the launch size, so under
gea.designWidth a new device pixel ratio stretched the old layout instead of
reflowing it. On a size change, resize the canvas and the root and refresh the
layout, and keep the display view on the safe area every frame, setting its
frame only when it moved.

generate-xcode-project.mjs took the design width only from `apps inspect`,
which the published CLI does not report yet. Fall back to the app's
package.json `gea.designWidth`, as build-windows.mjs does.

The Info.plist is portrait-only today, so the resize path is not reachable on
a phone yet; launch was checked on the simulator.

Compared on an iPhone 16 Pro simulator against a Chrome rendering of the same
stylesheet at the same 273 CSS px width. Each difference is now handled as
win32 handles it:

- Styled buttons. native_button took the first text child as a centred
  UIButton title and native_label hid every label inside a button, so city
  chips lost their temperature and the topbar pills and forecast tabs showed
  nothing. Buttons no longer carry a native title; their children render
  where the engine laid them out.
- Sideways rails moved twice as far as they scrolled. The engine already
  places a scroller's children at their scrolled positions, and the scroll
  view's contentOffset.x moved them again, so a tap after scrolling hit a
  different chip than the one drawn. Only a box that sets overflow-y
  auto/scroll itself becomes a scroll view now; a rail is a clipped plain view
  positioned by the engine's scroll_x, and the container's horizontal mode is
  gone.
- white-space: nowrap and text-overflow: ellipsis are honoured (one line,
  tail truncation or clip), so a chip name reads "San Fran…".
- Font weight. gea_host_measure_text_with_style is implemented, fonts are
  cached per size and weight, and a CSS bold with no heavier face is
  synthesized with Chrome's stroke amount, which leaves advances unchanged.
  The measured height is exactly lines x line-height, without the extra 1.
- Glyphs clipped by a short line-height. UILabel draws into its bounds, so
  `.temp` lost the bottom of its digits and line-height 1 labels their
  descenders. A label with a line box shorter than the font's natural line
  grows around its box. A corner radius alone no longer clips a view's
  children, which had cut the "y" off "Days".
- border-radius. No overlap scale-down and no percent radii, so 666px pills
  masked to nothing. Radii are resolved like macOS resolveRadii, text fields
  included.
- z-index. Siblings are ordered by z-index, then document order, reordering
  only when the order is wrong.
- A zero-size box hides its subtree only when it clips.

A synthetic swipe through the real touch path confirmed the city rail stops
at its maximum with the active chip moved once, not twice.

📝 Walkthrough

Walkthrough

The iOS and macOS targets now support design-width metadata and update platform runtime behavior. The changes also add iOS networking and Wi-Fi support, CSS-weighted text rendering, alpha-aware colors, and updates to native view layout, scrolling, and input handling.

Changes

Apple Platform Runtime and Rendering

Layer / File(s) Summary
Build resolution and design-width metadata
packages/geastack-apple/targets/ios/build-ios.sh, packages/geastack-apple/targets/ios/generate-xcode-project.mjs, packages/geastack-apple/targets/ios/Info.plist.in, packages/geastack-apple/targets/macos/build-macos.sh, packages/geastack-apple/targets/macos/Info.plist.in
Build scripts add collection-checkout package fallbacks. Both targets generate an optional GeaDesignWidth plist entry from app metadata.
iOS startup, viewport, and networking
packages/geastack-apple/targets/ios/main/ios_network.mm, packages/geastack-apple/targets/ios/generate-xcode-project.mjs, packages/geastack-apple/targets/ios/main/ios_main.mm
The iOS target adds an NSURLSession fetch backend and Wi-Fi driver. App initialization and viewport updates use design-width metrics.
Font, color, and text measurement
packages/geastack-apple/targets/ios/main/font_registry.*, packages/geastack-apple/targets/ios/main/renderer/native_label.mm, packages/geastack-apple/targets/ios/main/renderer/ios_renderer_internal.h, packages/geastack-apple/targets/ios/main/renderer/ios_renderer_support.mm, packages/geastack-apple/targets/ios/main/ios_main.mm, packages/geastack-apple/targets/macos/main/color_convert.*, packages/geastack-apple/targets/macos/main/font_registry.*, packages/geastack-apple/targets/macos/main/macos_renderer.mm
Font lookup and text measurement now use font weight and line height. The renderers apply synthetic bold and text alpha; color conversion accepts alpha values.
iOS view reconciliation and scrolling
packages/geastack-apple/targets/ios/main/renderer/*, packages/geastack-apple/targets/ios/main/ios_main.mm
The iOS renderer updates corner radii, clipping, child stacking, and native button content handling. Scroll synchronization uses shared offset accessors, and layout diagnostics can be enabled through GEA_IOS_LAYOUT_DUMP.
macOS native rendering and input
packages/geastack-apple/targets/macos/main/macos_renderer.mm
The renderer adds styled button views, horizontal overflow dragging and wheel scrolling, aspect-fill image rendering, and stable child ordering.
macOS viewport and event integration
packages/geastack-apple/targets/macos/main/macos_main.mm, packages/geastack-apple/targets/macos/main/macos_renderer.h
App initialization and viewport updates use design-width metrics. Content views forward wheel events to the renderer, and layout diagnostics include additional node style data.

Merge Risk: 🔵 Low · up to 1f547

On iOS, text line spacing can differ from the measured layout at non-unit scales. Plain-http fetches will fail without an App Transport Security exception. Both are small, bounded fixes that can be made before merge or accepted as a known follow-up.

Security Architecture Review

Security architecture risk: 🟡 Moderate · up to 1f547

Both Apple builds can use tooling from a neighboring checkout when installed packages are absent, making the contents of that checkout important to build integrity. iOS also gains real network access. No exploitable path is established, but these changes merit a design-level review.

Retained concerns

  • Medium · security · inferred: When installed packages are absent, both builds can select framework or toolchain inputs from a collection-relative checkout. Manifest existence alone does not establish that those inputs match the intended dependency versions or integrity; a changed checkout can therefore change subsequent build outputs. Whether that checkout is less trusted in actual build environments remains unverified.
Security review details

Security Blast Radius

  • inferred — The new outbound-request capability is limited by the evidence to apps built for this iOS target; destination and data exposure depend on the unexamined fetch callers. The build fallback can affect artifacts produced for either Apple target when installed packages are missing.

Security Findings and Attack Paths

  • inferred — If a party can alter a collection-relative package used when installed resolution fails, its contents can enter a subsequent Apple build. The available evidence does not establish such an attacker, a compromised checkout, or an attacker-controlled iOS fetch URL.

Trust Boundaries and Controls

  • observed — Installed-package lookup precedes collection fallback. Fallback package selection checks for a manifest; the inspected CLI path also checks its entrypoint. The iOS backend uses a default NSURLSession configuration, while its plist template shows no explicit transport-security exception.

Resilience and Maintainability Implications

  • observed — Request options are cleared before network execution and transport errors return an empty response. The synchronous seam waits for its completion callback; the inspected implementation shows no separate cancellation path for that wait.

Hardening Proposals

  • proposed — Make the collection fallback’s intended trust and version relationship explicit, and validate or pin selected package contents where builds must be reproducible or isolated from neighboring checkouts.
  • proposed — If fetch URLs or headers can come from untrusted app data, define the permitted destinations, redirect behavior, and credential handling at the facade-to-native boundary.

Plain-http fetches will fail on iOS without an App Transport Security (ATS) exception.

ios_network.mm now sends every fetch through NSURLSession. NSURLSession enforces ATS on iOS. The macOS Info.plist.in sets NSAllowsArbitraryLoads so that apps can reach plain-http endpoints, such as LAN devices and local dev servers. The iOS template has no ATS exception. On iOS, those requests fail with an ATS error. sessionFetch then returns an empty response. As a result, the new backend only works for HTTPS endpoints on iOS.

Choose one of these fixes:

  • Add an ATS exception. Prefer the narrow NSAllowsLocalNetworking key if LAN access is the only need.
  • Document that iOS fetch supports HTTPS only.

Review comment at @packages/geastack-apple/targets/ios/Info.plist.in at line 24:
Update the iOS Info.plist template near @DESIGN_WIDTH_KEYS@ to add an
NSAppTransportSecurity exception allowing local networking, so NSURLSession can
fetch from LAN and local development endpoints over HTTP while leaving other ATS
protections intact.

Use scaled line height when comparing and assigning minimumLineHeight.

font is created at fontSize, which is font_size * scale. The value font.ascender - font.descender is therefore in scaled points. node.style.line_height is still in layout px. textPaintFrame (Line 104) multiplies line_height by scale, but this code does not. If scale != 1, the comparison uses mixed units. The label then gets an unscaled minimumLineHeight, so its line spacing does not match the measured and painted box.

🐛 Proposed fix
-	if (font && node.style.line_height > 0 && node.style.line_height > font.ascender - font.descender)
-		paragraph.minimumLineHeight = node.style.line_height;
+	const CGFloat lineBox = static_cast<CGFloat>(node.style.line_height) * scale;
+	if (font && node.style.line_height > 0 && lineBox > font.ascender - font.descender)
+		paragraph.minimumLineHeight = lineBox;

150 - 151:
Update the minimum line-height logic to use scaled points consistently: in the
code that configures `paragraph.minimumLineHeight`, scale
`node.style.line_height` before comparing it with the font’s ascender/descender
metrics and before assigning it. Preserve the existing font and
positive-line-height checks.
