From cc5beb1985ddb8204154f023300e6a9d07e5f330 Mon Sep 17 00:00:00 2001 From: hermes-agent Date: Thu, 9 Jul 2026 09:03:52 -0400 Subject: [PATCH 1/7] fix(#640): clamp dark Material You surface family to static Slate ramp MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When Dark mode + Material You is enabled on Android 12+, dynamicDarkColorScheme returns a wallpaper-derived dark palette whose surface / surfaceContainerHigh / surfaceContainerHighest roles can resolve to high-luminance values for some wallpapers. The Routines screen reads these directly via MaterialTheme.colorScheme: - top app bar = surface (EnhancedMainScreen.kt:335) - bottom nav = surfaceContainerHigh (EnhancedMainScreen.kt:500) - expanded RoutineCard = surfaceContainerHighest (RoutinesTab.kt:1083) at elevation 8.dp (flickers to light vs collapsed 2.dp) Meanwhile surfaceContainerLowest stays dark, so the gradient anchors dark and the screen reads half-light/half-dark on the same scheme. The per-card expand/collapse flicker is the elevation tint amplifying that divergence. Fix: when dynamicColorEnabled=true and the resolved scheme is the dynamic dark scheme, route it through clampDynamicDarkScheme(dynamic, DarkColorScheme), which returns a ColorScheme whose surface family comes from the static Slate ramp (Slate950/900/800/700) while primary / secondary / tertiary / error / outline / surfaceVariant / background keep the wallpaper hue. Light + Material You and Material You = OFF are unchanged; iOS never invokes the helper. Tests: - ClampedDynamicDarkSchemeTest (9): boundary luminance 0/0.49/0.5/0.51/1.0, surface family swap, accent preservation, no-mutation, ≤ 6% adjacent shift - MaterialYouDarkClampContractTest (4): Theme.kt wires the clamp only on the dark branch; helper co-located with Theme.kt; DarkColorScheme unmodified - RoutinesChromeLuminanceContractTest (4): TopAppBar/BottomNav/RoutineCard continue to read from MaterialTheme.colorScheme (so the clamp propagates); no hardcoded Color.White containerColor - RoutineCardElevationContractTest (2): CardDefaults.cardElevation with if (expanded) 8.dp else 2.dp preserved so the elevation-tint shift is bounded Closes the Routines screen: expanded card flickers to light when Dark + Material You is enabled (issue #640).

The code matches the reporter's observed bug surface (those tokens are part of the same surface family that wallpaper-derived palettes miscalibrate), so the liar was the doc, not the code.

The conservative clamp originally stopped at background/onBackground, leaving inverseSurface dynamic — meaning a wallpaper that produces a light 'surface' would simultaneously produce a dark inverseSurface, and Snackbar would render dark-on-dark against the just-clamped dark screen. The exact same bug class #640 is trying to tame. This commit extends the conservative clamp to also pin inverseSurface and inverseOnSurface from fallback. The justification is the same as for the other surface family tokens: wallpaper-derived tonal palettes miscalibrate inverseSurface for some wallpapers, and Snackbar / Tooltip / similar components render in user-facing surfaces that must remain readable. Changes: - ClampedDynamicDarkScheme.kt: add inverseSurface / inverseOnSurface to the .copy(...) composition from fallback. KDoc updated to spell out the Snackbar dark-on-dark failure mode that this fixes. - ClampedDynamicDarkSchemeTest.kt: - extend the high-luminance dynamic fixture with explicit non-default inverseSurface / inverseOnSurface so the clamp assertion is meaningful - extend the conservative-clamp regression test to assert inverseSurface / inverseOnSurface == fallback - extend the broader surface-family equality test to assert inverseSurface / inverseOnSurface == fallback - fix the file-leading KDoc (was still listing surfaceVariant / background as 'from dynamic', contradicting the helper KDoc that commit 478cc6f had already reconciled) - extend the precondition assert to require the dynamic fixture differs from fallback on inverseSurface / inverseOnSurface too - MaterialYouDarkClampContractTest.kt: pin the new composition lines so a future refactor cannot drop inverseSurface / inverseOnSurface from the clamp without breaking a contract test.

Keeping both copies is a duplicate clamp check. Drop the assertions from the conservative-clamp test, leave a comment pointing at the broader test, and revert the precondition assert to the pre-3098c573 shape (no longer needs inverse tokens to differ). 2. **Reconcile KDoc token list.** The helper KDoc first paragraph enumerates 9 clamped tokens (incl. the inverse pair), but the second paragraph 'Why not pass these through from dynamic?' only listed 4. Rewrite the second paragraph to talk about the family as a whole ('Why not pass any of those tokens through from dynamic? They are all part of the same wallpaper-miscalibrated surface family.') so the rationale matches the enumeration width without spelling out the same long list twice.
