Owner 2026-08-03: «лучи поярче, иногда плохо видны. Убрать плавное
затухание — появляться и исчезать анимацией в 2 секунды при переходе
через 3 градуса над горизонтом».
RAY_MAX_ALPHA 0.18 -> 0.30: checked against both hard cases, a daylight
sun on white paper and a low sun over the dark glow canvas
(demo/shot_sun_bright.mjs writes the pair).
The gradual ramp-in over the first ~2 degrees is gone. rayAlpha() is now a
threshold: 0 below RAY_ELEVATION_MIN (3), rayPeakAlpha(cloud) at or above
it — cloud cover stays the only multiplier. Crossing it animates the
LAYER, never the geometry: <g class='sunlayer'> fades in/out over exactly
RAY_FADE_MS = 2 s (hp-sunfade-in / hp-sunfade-out), and the card keeps the
group mounted with .out for those two seconds so the dissolve can play at
all. prefers-reduced-motion skips it. Every other reason to drop the
wedges — editor, feature off, night, rain — stays instant.
Units: rayAlpha rewritten (ramp tests dropped), raysVisible/rayPeakAlpha/
RAY_MAX_ALPHA covered. Smoke: smoke_sun gains a threshold section (8 of
its checks fail on the previous build). docs/SUN.md + TESTING.md updated.
The wedge cache key carried the SERVER revision, which only moves after the
debounced houseplan/config/set is acked. Every local mutation path ends in
_saveConfig(), which bumps _cfgEpoch synchronously — so a dragged window or
an edited room kept its old wedge for the whole write window (forever on a
failed write). The memo now uses the epoch, the same signal the model/
geometry caches key on (audit L1).
smoke_sun.mjs no longer masks the defect: touchCfg() bumps _cfgEpoch (what
production does) instead of faking a server rev, and a new regression drives
the REAL path — a pointer drag of the east window, exit from the editor
inside the debounce window (rev untouched), a room shrink through
_saveConfig() that must re-clip the wedge, and a late-ack survival check.
Fails on b701537, green with the fix. 218 unit + 79 backend + 85/85 smokes.
- BG_STOPS: +10deg #e8ddcf (morning light), +30..90deg #ffffff; night half
of the scale untouched (-4 #131a28, -12..-90 #070c14)
- drawn-plan paper vs white sky: all paper shapes now sit in one
.hp-paperg group; in daynight mode the group gets a subtle
drop-shadow so the sheet contour stays readable at high sun
(static mode and night unaffected)
- pinned colors updated: test/sun.test.mjs, demo/smoke_sun.mjs;
smoke_bg_color paperUnderneath follows the .hp-paperg wrapper
- docs/SUN.md: explicit BG_STOPS table
- demo/shot_daynight.mjs: noon/sunset/night stills of the scale
