… app

The off-screen UIKit factory render was bunk: it rasterized DETACHED widgets at
scale=1.0, so a 30pt button was 30px inside a 1087px tile (tiny, wrong size), and
UINavigationBar/UITabBar rendered blank without a window. Replaced it for iOS with
the approach Shai asked for:

- scripts/fidelity-app/ios-native-ref/NativeRef.swift: a standalone native iOS app
  that lays each reference UIKit widget out in a REAL UIWindow and captures it with
  drawHierarchy(afterScreenUpdates:) -- so nav/tab bars render correctly -- at CN1's
  pixel density (so the PNG overlays the CN1 render 1:1, no scaling). Built directly
  with swiftc (no Xcode project) by scripts/build-ios-native-ref.sh, which runs it on
  the simulator and copies the PNGs into the committed iOS goldens.
- run-ios-fidelity-tests.sh: iOS now compares the CN1 render against these COMMITTED
  goldens (generated offline, not same-run) instead of the broken factory native.
- ProcessScreenshots: tolerate a few px of cross-environment rounding (golden 1088 vs
  CN1 1087) by cropping both to their common top-left region before diffing -- a true
  1:1 overlay, never a scale.

Result: all 50 iOS pairs now compare against real, correctly-sized native widgets
(Toolbar was 0% blank -> a real centred-vs-left-aligned title diff). Seeded the iOS
ratchet baseline (mean 62.3%); the low scores are the genuine untuned-iOSModern-theme
gaps to drive up next.

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

The old score was the mean colour agreement over all widget-content pixels, so a
large flat region that happened to match -- e.g. a dark nav-bar fill against a
dark tile -- could carry the score into the high 80s even when the actual widget
(the title) was centred in one render and left-aligned at a totally different
font size in the other. "Mostly got points for being black."

Now fidelity = min(fillSim, structSim):
  - fillSim   = mean colour agreement over content pixels (the old term; catches
                wrong fill colours).
  - structSim = the same agreement WEIGHTED BY local-gradient salience SQUARED, so
                flat fills count for ~nothing and the strongest edges -- glyph
                strokes, crisp outlines, separators -- dominate. A mis-placed or
                mis-sized title lands its strokes on the other render's flat fill,
                collapsing this term.
A widget must now agree in BOTH fill AND structure/placement. Effect on the iOS
Toolbar that triggered this: 89.3% -> ~59% (dark) / 36% (light), matching the
independent SSIM (~56%), while genuinely-similar widgets (an off switch, disabled
buttons) stay in the mid-80s. This is stricter for Android too; the CI seed run
reseeds both ratchet baselines under it.

Per Shai's note that the native toolbar/widgets weren't using the modern look,
the native-reference app now uses the iOS 26 Liquid Glass options:
- buttons: UIButton.Configuration.glass() (tinted action), prominentGlass()
  (filled/CTA -> a real glass capsule), clearGlass() (borderless text button).
- UINavigationBar / UITabBar: standard + scrollEdge appearances configured with
  configureWithDefaultBackground() = the glass material, not the legacy opaque
  fill.
Regenerated the committed iOS goldens. (The glass translucency reads subtly over
the flat reference tile -- its blur only develops over scene content, which we do
not put behind the widget so the diff stays widget-vs-widget -- but the modern
configurations/appearances are now what the reference uses.)

Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Liquid Glass only reveals itself over content behind it, so the glass widgets
(buttons, nav/tab bars) are now rendered over a single committed backdrop --
glass-backdrop.png, a simple smooth diagonal gradient. The SAME PNG is used by
both sides (the native NativeRef app bundles it; the CN1 FidelityDeviceRunner
loads it as the tile background for the glass component ids on iOS), so the only
difference left between the two renders is the glass itself, not the background.

A smooth gradient (no hard edges) is deliberate: it makes the frosted glass
clearly visible while adding almost no gradient "structure", so the
salience-weighted metric keeps scoring the widget difference rather than being
inflated by a matching backdrop. Non-glass widgets and all of Android stay on the
plain tile.

Regenerated the iOS goldens; the CI iOS run reseeds the baseline against them.

Tuned against the stock-M3 TabLayout golden (Tabs light 83.9 -> 92.3,
dark 90.7 -> 95.2):

- tabsEqualWidthBool: tabsGridBool alone leaves the tab row scrollable,
  and a scrollable grid sizes every cell to the WIDEST tab -- the three
  tab centers drifted up to 12px off the native fixed-tab thirds. The
  non-scrolling grid divides the row exactly like TabLayout.
- Labels at 2.25mm (14px = M3 labelLarge at the 160dpi contract; the
  old 2.5mm rendered 15-16px glyphs) with an explicit 1mm icon-gap to
  reproduce TabLayout's icon-to-label spacing; the active tab keeps
  bold as the closest stand-in for native's medium weight.
- Bottom padding 2.1mm -> 1.75mm: the bar's bottom edge sat 2px below
  TabLayout's, which cost two full-width rows of diff in both
  appearances.

Also make xvfb-run conditional in build-android-{app,port}.sh so the
local (macOS) fidelity loop can run the same chain CI does.

Dialog dark 89.9 -> 95.8, light 92.5 -> 95.7 against the AlertDialog
golden. The CN1 card rendered 26px wider and 15px shorter than native:

- DialogButton: 14sp label (2.25mm) with 12dp horizontal padding --
  the 2.5mm/2.5mm text buttons pushed the command row ~20px wide.
  Restated in the dark override (dark styles replace wholesale).
- DialogCommandArea: 24dp top padding places the action row the M3
  distance under the supporting text; its absence shortened the card.

The M3 Tabs and Dialog tuning (equal-width cells, 14px labels, command
row metrics) legitimately changes the four *Theme screenshots on the
Android port; renders verified against the previews (evenly divided tab
row, correctly spaced dark dialog card).

Also remove the LETTER_SPACING "Since" doc section: the merge-conflict
resolution resurrected a block master had deleted, and the new

Same four *Theme screenshots as the Android port, rendered through the
JavaScript port; verified equal-width tab cells and the retuned dialog
command row. The fifth diff in that run (graphics-draw-image-rect
delivering a mostly blank frame) is the JS async-render capture flake,
not accepted -- the rerun re-renders it.

The Linux port stages AndroidMaterialTheme.res as its native theme, so
the equal-width tab cells and dialog command-row metrics churn the same
six screenshots on both arches (Tabs/Dialog themes plus the
TabsAnimatedIndicator and TabsBehavior renders of the same bar).
Verified the x64 render: evenly divided tab row, correct labels and

Fidelity vs the iOS 26 golden set: Toolbar dark 72.4 -> 87.2, light
78.7 -> 87.0, Tabs dark 80.9 -> 84.2, Tabs light 84.0 -> 85.3, and the
FlatButton family +1.3-2.1 (suite mean 92.9).

- Tabs dark rendered the selection drop as a SOLID accent pill: the
  lens's dark->accent keying is a light-mode premise (dark glyphs over
  light frost turn blue); on a dark bar everything under the drop is
  dark so the whole capsule flooded. The lens now keeps only its
  magnify/aberration optics on dark bars and the selected glyph carries
  the accent directly (theme TabIcon.selected + the fidelity renderer).
- Toolbar: the nav-bar circles sat flush at the screen edge; native
  insets the items ~2.6mm (leading/trailing margins, restated in the
  dark overrides). Removed the bar-wide backdrop blur + dark tint --
  the native iOS 26 bar is effectively invisible, only the floating
  items and title sit on the backdrop; the old blur painted a frost
  band the reference does not have. Dark circles darkened to the
  measured hue-preserving fill.
- Frost levels sampled against the golden over the shared backdrop:
  the tab pill is ~22% white over a LIGHTLY blurred local backdrop
  (was 0.82/blur40, which washed and cross-mixed colours); FlatButton's
  clearGlass fill is nearly invisible (0.32 -> 0.16) with the native
  2.1mm text inset.

The toolbar item insets, removed bar-wide frost, dark lens polarity and
frost-level changes legitimately churn every themed screenshot with a
toolbar/tabs/flat-button surface: 4 on the iOS simulator suite
(ButtonTheme_dark, TabsTheme_light, ToolbarTheme light+dark) and 32 on
the Mac native suite. Spot-verified: the dark tab bar renders the blue
selected glyph on a subtle capsule (no solid accent pill), the toolbar
strip is band-free with inset circular items, and the button gallery's
Flat variant shows the near-invisible clearGlass fill.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

Same theme-wide churn as the iOS + Mac sets: 32 themed screenshots on
the Metal and tvOS suites and 4 on watchOS pick up the toolbar item
insets, removed bar-wide frost, dark lens polarity and measured frost
levels. Spot-verified the Metal dark tab bar (blue selected glyph on a
subtle capsule inside the dark pill). Only the gate-flagged tests were
accepted; sub-threshold delivered renders were restored to keep the
byte-identical baseline clean.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

With the Liquid Glass surfaces on the themed screens, the tvOS 4K Metal
renders carry small run-to-run GPU noise (channel deltas up to ~40
across the glass area) -- unlike the iOS, Metal-phone, Mac and watch
suites, which validated the accepted goldens deterministically. The
default channelDelta=4 gate can therefore never settle on tvOS: two
consecutive runs flagged the same 32 tests against each other's
renders.

Use the comparator's existing per-test override (<test>.tolerance) to
allow the measured noise band (maxChannelDelta=48, maxMismatchPercent=1)
on exactly those 32 tests, and re-anchor their goldens to the latest
run. Anything beyond the noise band, or moving more than 1% of pixels,
still fails.

The centred nav-bar title sat 5px below the native baseline (fidelity
tile y48 vs native y43): asymmetric Title vertical padding lands it on
the native row (Toolbar light 86.95 -> 87.64). The tab pill's blur
radius drops 24 -> 14px: 24 still dragged neighbouring backdrop colour
across the pill where the native frost stays local.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

The glass round (pill fill 0.22, tighter blur, dark lens polarity)
legitimately changes every frozen TabsMorph animation frame -- light
frames drift ~37% of pixels (the old 0.82 white fill), dark ~16% (the
removed tint flood). Verified the dark strip: the capsule travels with
the blue glyph readable at every t and no accent flooding.

Also anchor the ratchet baselines to the CI run's improved scores
(Android: Tabs 92/95 + Dialog ~96 round; iOS: Toolbar 87.7/87.6,
Tabs 84.2/85.3 round) so the gate ratchets from the new levels.

The title-baseline/tab-blur commit (87fca6f) landed after the last
watch/mac/metal golden refresh, so all three suites flagged their themed
screens (title text shift + tab pill frost): watch 30, mac-native 27,
metal 10 -- reviewed, benign, accepted. tvOS absorbed the same churn via
its per-test tolerance files.

build-ios also failed a 4th time on a different infra signature: the
booted simulator vanished between simctl boot and xcodebuild ("Unable to
find a device matching the provided destination specifier" after a 406s
boot). run-ios-ui-tests.sh now restarts CoreSimulator, re-boots or
recreates the device, and retries the build once when it hits that exact
error.

Tabs (all measured against the native golden at @3x):
- The selected pill is 276x175px on a 179px bar -- wider than its CELL
  (overlapping neighbours) with only ~2px of rim. bubbleWidthPct 96 -> 109
  in the ios26 preset and tabSelInsetMm 0.6 -> 0.12 take the CN1 capsule
  from 236x161 to 269x180.
- The drop must never leave the bar: a bar-bounds clamp in
  TabSelectionMorph.compute trims the overshooting end-cell drop (it
  compresses against the bar end instead of painting the backdrop).
- The vertical lens overflow is now a FLIGHT effect: the settled pill sits
  fully inside the bar like native; a constant overflow left a tinted
  crescent past the bar's rounded ends at rest.
- Tab labels: 1.65mm MainRegular with a remeasured vertical split lands the
  glyph rows exactly on native (117-137 vs 117-136).
- Frozen-frame pins + a new wideDropStaysInsideTheBar test cover the clamp
  and the rest-overflow change; 14 TabsMorph frame goldens refreshed.

CheckBox / RadioButton via real SF Symbols (opt-in iosSFStateIconsBool):
the Material radio glyph draws ring 10px / gap 17px / dot 53px where the
native symbol is 8/8/77 -- no theme constant can fix a glyph ratio. The
state icons now render checkmark.circle.fill / largecircle.fill.circle /
circle through createSFOrMaterial, sized 5.9mm so the rendered circle
lands on the native 108px (the global iosSFSlotPct 115 tab tuning inflates
SF renders). RadioButton 90.4 -> 94.2, CheckBox 92.9 -> 94.9.

Suite: mean 92.9 -> 93.4, median 92.7 -> 94.0.

the CheckBoxRadio/Tabs/Showcase/FAB/PaletteOverride themed screens across
the CN1SS suites: ios 10, metal 6, watch 6, mac-native 6, tvOS 2 (the

… track

All sampled from the native UISwitch goldens @3x:
- The thumb is a WIDE capsule nearly filling the track (106x74 off / 104x67
  on, ~5px rim) -- the shipped 1.4/0.22mm/1.35 knobs drew a small 84x62
  floating knob. switchThumbScaleY 1.55, inset 0.1mm, widthScale 1.4.
- Disabled dark: native dims the thumb to #808080 over a #232325 track;
  ebebf5/3a3a3c read as an enabled off switch (85.3% -> 95.5%).
- Dark off track is #464649, not the #2c2c2e surface colour.

Switch component 91.9 -> 95.4; suite mean 93.4 -> 93.8, median 94.0 -> 94.5.

The larger native thumb (1.55/0.1mm/1.4), the #808080/#232325 disabled-dark
pair and the #464649 off track change the SwitchTheme screens on ios, metal,
watch and mac-native (tvOS absorbed by its glass-noise tolerances).
Reviewed: the on/off thumbs now nearly fill the track like the native
UISwitch, no artifacts.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

The larger thumb (1.55/0.1mm/1.4) changes every SwitchMorph animation
frame; the strip renders the intended slide (droplet stretch mid-travel,
grey-to-green track fade) with the new geometry. Frames taken from the CI
run so they match the device renderer exactly.

…ndex fix

Two real renderer bugs, found comparing against the native UIPickerView:
- The iOS perspective transform ran PER CHARACTER (each glyph individually
  wedged, re-kerned with a fixed -4px overlap) which broke letter shapes and
  spacing on every off-selection row. Rows now render as ONE image and the
  perspective transforms the composed row, like the native cylinder.
- The perspective INDEX mapping was inverted: perspective = rawDistance gave
  the row ADJACENT to the selection the heaviest wedge (index 1, 0.55 shrink)
  and the farthest row the mildest. Distance d now maps to FRONT_ANGLE -/+ d.

Also measured against the golden: off rows dim to a near-uniform tertiary
grey (~0.32 of the label colour), not a steep distance ramp; taper softened
(native rows keep their glyph shapes); row pitch 0.4mm insets to land the
native ~87px @3x row spacing (was 110).

Spinner 89.9 -> 91.6; the remaining gap is the wheel's wrap-around edge rows
(native pickers do not wrap short models).

The iOS gesture MISS flakes were a capture race, not lost gestures: the
background `log stream` takes seconds to attach its predicate and
xcodebuild can drive the first gestures before it is live -- a CI run's
device.log started 16s into the test and lost CN1IV:EVENT:tap while the
XCUITest itself passed. After the run the driver now appends
`log show` (the persisted unified-log archive, immune to the attach race)
so the event assertions grep the union of stream + archive.

Review findings addressed:
1. CI no longer bypasses the gate: FIDELITY_UPDATE_BASELINE removed from both
   fidelity jobs. The committed baselines are re-anchored from the latest
   green CI run (28699482712) and both gates verified passing against them;
   re-anchoring is now a deliberate local act committed in a PR.
2. Baseline update mode refuses partial runs: FidelityGate fails (exit 20) on
   any missing/error pair BEFORE writing a baseline, so a broken run can no
   longer ratchet only its survivors.
3. Frame validation is fail-closed: MorphFrameValidator errors when a
   spec-declared frame group delivered nothing (previously it grouped only
   delivered files, so a dead capture pipeline validated green), the runner
   always invokes it (no FRAME_COUNT>0 skip), and --seed-missing is only
   passed under FIDELITY_UPDATE_GOLDENS=1 -- CI can never self-approve
   missing frame goldens.
4/5/6. Geometry honesty: the report's MAIN table now carries a Geometry
   column flagging pairs whose bbox is materially off-native (center offset
   >6px, size ratio outside 0.90..1.10) even when the tolerant overlay score
   is high -- TabOne's 95%+ score now reads "OFF (w 0.75, h 0.54)". The
   geometry ratchet itself was already in FidelityGate and is now actually
   enforced with the bypass gone.
7/8. COVERAGE.md refreshed from the committed baselines (the same numbers the
   gate enforces, so the doc and gate cannot disagree), with a new "what the
   scores do and do not claim" section (tolerant overlay vs geometry, glass
   isolation scope, frames validate CN1 determinism NOT native motion) and an
   honest known-visual-gaps list.

Also merges master (4 commits, website/blog only).

The log-show fallback recovered the stream-attach race but CI then showed
unified logging DROPPING interleaved lines under burst pressure (READY:drag
persisted, EVENT:drag emitted milliseconds later did not -- missing from
both `log stream` and `log show` while the XCUITest passed). os_log is
lossy by design, so the app now rewrites its full CN1IV transcript to a
file in the app home on every event; the driver reads it from the app
container after the run and the greps run against the union. Console
output stays as the live-progress channel.

The Windows cross pipeline never set CN1SS_FAIL_ON_MISMATCH, so it posted
its diffs to the PR and exited green -- 107 of 138 renders currently
differ from the committed baseline unreviewed. The gate is now armed;
the job is EXPECTED to fail until the renders are fixed and the baseline
is reviewed+refreshed.

Among the diffs is a real regression: default-theme screens that run
after the dual-appearance tests render with the native (material) base
missing (title/chrome falls to the legacy grey cccccc instead of the
material fef7ff surface). The same wrong renders were blanket-accepted
into the Linux GTK goldens and must be re-reviewed. Each capture now
logs a CN1SS:DIAG:theme line (resolved TitleArea/Toolbar/Form styles +
dark mode) so the CI device log pinpoints where the theme state
degrades; the diagnostic is temporary.

Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>

…ed gate

The diagnostic dispatch run pinned down the "grey title" churn: it is NOT
a theme-state bug. The app's own theme styles GraphicsForm with a #cccccc
background (identical on master), and the graphics-family screens set that
UIID on their Form. Master's fef7ff title strip on those screens was the
material theme's OLD opaque TitleArea surface painting over the app's grey
form; this branch's material work made TitleArea transparent (the measured
M3-correct look that fixed the toolbar fidelity), so the app's grey now
legitimately shows through the title strip. The state is order-independent
(MainActivity/charts/Validator render the material surface before AND after
the graphics window) and the renders are byte-deterministic across runs
(138/138 identical between two CI runs).

Diff taxonomy accepted into the new baseline:
- *Theme screens: the Android Material / iOS Modern theme tuning churn
  (same category already reviewed on the ios/metal/watch/mac suites);
- graphics-family screens: the TitleArea-transparency consequence above;
- text-metric shifts (landscape etc.): the letterSpacing/derived-font work.

The temporary CN1SS:DIAG theme probe is removed; the armed
CN1SS_FAIL_ON_MISMATCH gate stays, so any future drift fails the job
instead of posting-and-passing. The Linux GTK goldens accepted earlier on
this branch carry the same (now explained) categories and stand.
