Items 2, 3 and 6 of the Xcode 27 migration as one change. Toolchain (CN1_XCODE_MAJOR), the ios.themeGeneration default and the 27.1 foldable CI are deliberately not here.

The dark glass curve (item 3)

iOS 27's dark Liquid Glass is not affine. After the best affine fit the residual is a parabola in backdrop luma. GlassRecipe gains a curve term, curve * 255 * (lum/255 - curveMid)^2, carried by dark chrome27 and pill27.

tile (device, iOS 27.0 sim) before after
Tabs dark 68.75% 73.45%
TabsGeom dark 87.73% 90.72%
mean (68 tiles) 92.83% 92.95%

The dark panel stays affine. Its curve took the offline fit from rms 3.59 to only 3.18, and on device it cost three tiles about 0.3 each, so it was measured and dropped. chrome27 is fitted but not device-verified: the suite's Toolbar tile paints no glass, and its score was byte-identical across the change. That's recorded in the javadoc.

The edge outline, and why it unblocks the gate (item 2)

The ios-27-metal baseline couldn't be recorded because GlassPanelGrey/GlassPanelRed in dark had no CN1 silhouette, and FidelityGate correctly refuses a one-sided empty. The cause turned out not to be the material. iOS 27 draws a thin dark line around the sides of its panel and pill glass, in both appearances, and iOS 26 does not. On the boundary pixel, each backdrop channel b becomes max(b - 76, 0.22 * b) to within a few levels, across grey, red, gradient and photo backdrops.

GlassRecipe.getOutline() carries it (panel27 0.95, pill27 0.55, measured). The optics draw it on the outermost pixel, weighted by the horizontal component of the edge normal. Both formerly empty tiles now match the native bounding box to 1–2 px and the corner radius to within 0.5 px.

Raising the specular rim instead was tried first and rejected. It overshot the rim on the other backdrops about 2:1 and cost every other dark panel tile 0.1–0.9.

Both terms are in every glass backend:

  • iOS offscreen (Java)
  • the iOS and MacPort live Metal CPU paths, including the patch-cache key
  • JavaSE
  • the JS bridge

verify-javascript-lens-parity.mjs pins them bit for bit: two material pins and three outline pins, with checksums from the iOS and JavaSE implementations. Zero curve and zero outline short-circuit, so every iOS 26 recipe renders as before.

With the baseline committed, fidelity-ios-metal-27 loses its continue-on-error, and the drift guard no longer allows it in the copy. A local run in CI mode (CN1SS_FAIL_ON_MISMATCH=1) passes: 68/68 at or above baseline, 4 morph groups validated.

Motion references (item 6)

goldens/ios-27-metal-anim:

  • Native tabs (tap-driven through the XCUITest driver, home-screen lead-in trimmed) and native switch recordings, from the iOS 27.0 simulator under Xcode 27.
  • The CN1 morph, rendered on that same simulator by freezing Tabs.setMorphTestState at each 60 fps timeline value, rather than in JavaSE as the iOS 26 set was.

The README explains each.

Expected CI follow-up

build-ios-metal-27 renders hellocodenameone with the iOS 27 theme, so its glass captures will move. Those goldens are reseeded from that leg's artifacts, after checking the diffs are glass-only.

iOS 27's dark Liquid Glass is not affine: after the best affine fit the
residual is a parabola in backdrop luma. GlassRecipe gains a luminance curve
term, curve * 255 * (lum/255 - curveMid)^2, carried by the dark chrome27 and
pill27 recipes. On device the pill tiles moved with it (Tabs dark 68.75% ->
73.45%, TabsGeom dark 87.73% -> 90.72%). The dark panel stays affine: its
curve improved the offline fit slightly but cost three tiles 0.3 on device.

iOS 27 also draws a thin dark outline around the sides of its panel and pill
glass, in both appearances, which iOS 26 does not. On the boundary pixel each
backdrop channel b becomes max(b - 76, 0.22 * b) to within a few levels across
grey, red, gradient and photo backdrops. That outline -- not the material --
is what makes the native dark panel visible over a flat grey, so without it
GlassPanelGrey/Red dark rendered no silhouette and the fidelity gate rightly
refused to baseline them. GlassRecipe.getOutline carries it; the optics draw
it on the outermost pixel, weighted by the horizontal component of the edge
normal. Both formerly empty tiles now match the native bounding box to 1-2px.

Both terms are implemented in every glass backend -- iOS offscreen (Java),
the iOS and MacPort live Metal CPU paths (including the patch-cache key),
JavaSE and the JavaScript bridge -- and pinned bit-for-bit across the Java and
JS implementations in verify-javascript-lens-parity.mjs. Zero curve and zero
outline short-circuit, so every iOS 26 recipe renders exactly as before.

The ios-27-metal fidelity baseline is recorded and fidelity-ios-metal-27 is
now a real gate (continue-on-error removed, drift guard updated). The
TabsMorph frame goldens are reseeded for the new pill material, and
goldens/ios-27-metal-anim holds the tap-driven native tab and switch motion
recordings plus the CN1 morph rendered on the iOS 27 simulator.

Native Windows port (arm64 / Apple Silicon - Arm): full hellocodenameone screenshot suite rendered offscreen with Direct2D/DirectWrite, plus the real benchmarks (base64 native/CN1/SIMD, image createMask/applyMask/modifyAlpha/PNG/JPEG, NEON SIMD kernels). Compared against the in-repo baseline in scripts/windows/screenshots.

Reseed the iOS 27 TabsTheme_dark golden for the curved dark pill mate…
f9d5386 
…rial

The only capture of 155 the build-ios-metal-27 leg reported as changed; the
difference is confined to the tab-bar pill (rows 2191-2435), which now carries
the dark pill27 luminance curve and the iOS 27 edge outline. Taken from that
leg's CI artifact.

Stop test flags leaking between classes: the MenuBarDialogSideMenuTes…
b1f7ea6 
…t failure

menuBarAddsCommandsAndTracksDefaults failed intermittently on build-test (21),
here and on unrelated PRs, with "Second command should have a bound button in
button bar mode". It is not intermittent -- it is order-dependent.

DialogInWindowTest set touchDevice true for one test and in its finally set it
to false, not to the value it found; the test implementation defaults to true.
TestCodenameOneImplementation.reset() never restored touchDevice, so every test
after it in the JVM ran on a "non-touch device", where
CodenameOneImplementation.setCommandBehavior turns COMMAND_BEHAVIOR_BUTTON_BAR
into SOFTKEY and MenuBar creates no command buttons. Surefire runs classes in
filesystem order, which differs between checkouts, so the failure appeared only
when DialogInWindowTest happened to run first.

Reproduced by replaying the failing CI run's exact class order in one JVM on
JDK 21 (4411 tests, 1 failure: this one), and reduced to the pair
DialogInWindowTest -> MenuBarDialogSideMenuTest, which fails while the latter
alone passes. With the fix both the pair and the full replay pass.

reset() is the choke point, so it now restores all six setter-backed fields it
was missing (touchDevice, portrait, tablet, trueTypeSupported,
autoProcessConnections, locationButtonReady) to their declared defaults, and
DialogInWindowTest restores the value it found. None of the six is set in any
@BeforeAll, so no class relies on one surviving a test's teardown; the full
suite passes 7338/7338.

VaultTest: close the race that let a "blocked" device prompt run free
d56e69e 
aRememberPromptCannotPublishAKeyReplacedByRotationOrImport failed on
build-test (21) with "replacement 1 ==> expected: <CONFLICT> but was: <null>".
The vault was right; the fake device store was not holding the prompt.

FakeDeviceProtection.ensureKey counted down ensureEntered and only THEN read
releaseEnsure. Counting down wakes the test thread, whose next step clears
releaseEnsure so the replacement's own ensureKey does not block. When that
clear landed first, the prompt under test skipped its wait, ran alongside the
rotation/import, finished before it changed anything and reported success.
The fields were also plain, so the worker was not even guaranteed to see them.

The latch is now read before entry is announced, and both fields are volatile.
Proven with a probe that sleeps between the two steps to widen the window: the
old ordering then fails deterministically with the CI message, the new one
passes under the same sleep. The probe is removed; VaultTest passes 153/153 and
the full suite 7338/7338.
