With the day/night background the plan went blurry after zooming from 100 %
(sharp when the page was opened at 800 %) and navigating a strongly zoomed
plan flashed the page white. Both came from #582's composition, not from the
wall hatch that #685 replaced:
- `.stage.daycycle.hp-safe-daycycle-outline .plan-svg` promoted the scene
with `will-change: transform`; Chromium freezes the raster scale of such a
layer, so the 100 % raster was shown stretched. The explicit layer #582
needs is now `will-change: opacity` (re-rasters at the current scale).
- The filtered outline had `overflow: visible` and a gesture exposed every
scene (#544) without bound, so the promoted layers grew with zoom squared
(CDP LayerTree, ~460 %: plan-svg 15.9x, outline 13.2x the stage; 39x after
navigating at 800 %). The full card clips its outline to its box and marks
it data-hp-live-overflow="clip" (never exposed); the live viewport bounds
every other exposure with an inline clip-path: inset(-25%) that leaves
with it, so idle DOM stays byte-identical (#531).
Owner-verified in Chrome 152 (built-in browser, DPR 2): sharp after 100 ->
800 %, no white flashes after reloading at 800 %.
Owner decision: #685's analytic gradient is reverted (13af1d5e), the single
<pattern> is back at every zoom; its close-up golden scenes stay and check
the pattern, its terminal-frame smoke checks the pattern.
Witnesses: demo/smoke_daycycle_zoom_layers.mjs (800 % x DPR 2: layers vs
stage, the hint, reload path, button/wheel/pinch); #582/#532 smokes now pin
the opacity hint; test/live-viewport.test.mjs (bounded exposure, clipped
scene); test/daycycle-layers.test.mjs (cascade). Four Node-guarded mutants.

Code review r1 found two documentation claims that the task's own contract
contradicts.
Both changelogs promised the picture was unchanged "to the pixel". It is
not: splitting the layer moves the wall hatch by a sub-pixel, and that is
exactly why four day-cycle baselines are re-taken. The entry now says what
a reader can check — the outline around the plan matches pixel for pixel,
the hatch inside the walls is anti-aliased a shade differently.
docs/SUN.md credited Firefox with the fifteen-fold ratio. That number comes
from headless Chromium through CDP tracing; the Firefox profile that opened
the issue measured the same cause differently — 23 MB of texture uploads per
frame and about nine frames per second. Each number now names its engine.
Issue: #532
User-Visible: no
The "Follows the sun" background made the plan crawl in Firefox: 23 MB of
textures per frame, sixteen of about twenty picture-cache tiles thrown
away every frame, nine frames per second. The card's own JavaScript was
idle for 89 % of that.
The cost is the outer outline. It is a triple drop-shadow over the
grouped paper footprint, and although the group holds paper silhouettes
only and never changes on hover or pan, the filter lived in the plan's
own layer — so every repaint of the plan re-ran three blur passes over
the whole sheet. One hint moves the filtered paper into its own layer
and unhooks it from the plan's repaints.
Measured on a demo-stand pan (Chromium, CDP, summed RasterTask): 1456.6
ms against a static background's 96.7 ms before, 84.7 ms against 103.2
ms after. The new smoke measures that ratio and fails above two.
The picture does not change: the outline outside the plan matches byte
for byte and the frame's mean colour moves from 176.59 to 176.66 of 255.
Splitting the layer does move the remaining content onto a different
sub-pixel grid, so the diagonal wall hatch anti-aliases differently and
the four day-cycle baselines are re-taken on the beta candidate.

Audit finding P2. At a grazing sun the wedge lost the two invariants it
was supposed to keep: one end of the GLASS started at opacity 0, and the
two sides of one shaft came out 5.41 and 84.19 long — the long one 31 %
LONGER than the pre-cut 64, not 30 % shorter.
The cause was the axis. The gradient ran along `dir` from the middle of
the window span, so the geometry had to be skewed (each end extruded by
a different amount) to make both far corners land on the same offset.
That buys the iso-alpha far edge with the other two requirements.
The light is a bundle of PARALLEL rays: the distance a point has
travelled from the glass is depth/cos, an affine function of the point,
whose level sets are lines PARALLEL TO THE WALL. So the correct linear
gradient runs along the wall's INWARD NORMAL, starts on the window line
and is `len·cos(incidence)` long — SunRay.normal / SunRay.depth. A point
`source + dir·u` then lands on offset u/len, whichever ray it rode in
on. All three invariants hold at once:
* the whole pane of glass is at depth 0 → peak alpha end to end;
* alpha depends only on how far that point's own ray has run;
* rayQuad() is an honest parallelogram again (both ends extruded by the
same `len`), and its far edge — parallel to the wall — IS the
gradient's last iso-alpha line, so a bright kerb is impossible by
construction and the −30 % holds for every side of every wedge.
windowLit() gets a real threshold instead of the 1e-9 epsilon:
RAY_MIN_COS = 0.05, i.e. the sun must clear the plane of the wall by
~2.9°. Below it glass reflects nearly everything and the shaft would be
a sliver thinner than the wall it came through — nothing is drawn, and
the gradient axis can never degenerate to a point.
Tests: rayQuad now asserts equal, full-length sides and a wall-parallel
far edge; new unit tests replay the auditor's repro with his numbers
(both sides 44.8, offsets 0 at both ends of the glass, offset = travel /
len for arbitrary rays) and the RAY_MIN_COS cut-off. smoke_sun_soft
measures the same facts off the DOM gradient end to end and fails by
name on the old bundle (9 named failures). docs/SUN.md carries the new
contract and the finding.
Owner, 2026-08-04, on yesterday's attempt: «с лучами солнца ты сделал фигню —
не надо размывать их боковые грани».
They are right. 22b588e answered "the shafts run into something invisible" with
a Gaussian blur of the WHOLE wedge (`raySoftness`, filter `hp-sunsoft`), which
feathered the sides as well as the tip. A shaft of light through a window has
crisp sides; only its reach fades. The blur turned every wedge into a smudge.
GONE. `raySoftness()`, the `<filter>`/`feGaussianBlur` in <defs>, the `<g
filter clip-path>` wrapper, and with it the `hp-sunclip` clipPath — that clip
existed only so the blur could not bleed through a wall. The polygons come out
of `computeSunRays()` already intersected with the room, so a wall still stops
the light by geometry (demo/smoke_sun.mjs, wedgeClippedToRoom). The sun layer
is plain `<polygon fill="url(#hp-sun-i)">` again.
THE KERB DID NOT COME BACK, and not by luck. The old bright edge floating in
mid-floor was never about softness: the gradient's iso-alpha lines are square
to the SUN, while a parallelogram's far edge is parallel to the WALL. Head-on
they coincide; at any other angle one far corner sits at offset `1 − 0.5/k` —
0.71 of the way at a low sun, 0.11 at a high one — i.e. still lit when the
polygon ends. So `rayQuad()` no longer builds a parallelogram: each side is
extruded until it reaches the same distance `len` ALONG `dir`, which puts the
far edge on one iso-alpha line of the gradient. Combined with the untouched
`RAY_FADE_END` = 85 %, the last 15 % of every wedge is empty and its outline
has nothing left to draw. The sides stay razor-sharp on purpose.
Length (×0.7) and the live sky catch-up are untouched.
Tests: unit — `rayQuad` at six sun angles (sides exactly parallel to the ray,
both far corners at offset 1, far edge ⊥ ray, nothing past the gradient) plus
the head-on parallelogram pinned; the `raySoftness` test is gone with the
function. Smoke — demo/smoke_sun_soft.mjs keeps the reach and the "dead at
85 %" checks and flips the feather assert into its opposite: no filter on any
wedge, no `feGaussianBlur` in the tree, and at an OBLIQUE sun (230°/8° and
225°/55°) no vertex is drawn past the end of the gradient. Verified to fail on
the previous bundle on exactly those four. All 247 unit tests and all 97 smokes
green. Stills: sun_sharp_low / sun_sharp_high (demo/shot_sun_short.mjs now
takes a file prefix).
Owner, 2026-08-04: «цвет фона не меняется сам с течением времени суток, только
после обновления страницы».
WHAT IS NOT THE BUG. The model layer was already live: `_stageBg` and the
`planDim` filter are read straight out of `hass.states['sun.sun']` on every
render, `hass` is a plain reactive property, and a bare `card.hass = {...}` in
the demo rig does move the style attribute — smoke_sun.mjs has asserted exactly
that since v1.56.0 and it has always passed.
WHAT IS. The sky is DELIVERED by a 45 s CSS transition, and a CSS transition
only advances while the element is being painted. Every second of a background
tab, another dashboard view, an editor session or a sleeping wall tablet is a
second the sun keeps moving and the sky does not; when the card comes back, the
transition restarts from the stale colour and crawls, 45 s at a time, toward a
target that has meanwhile moved again. A page reload, by contrast, paints the
right colour outright — a freshly mounted element has nothing to transition
FROM. That is the owner's sentence, word for word.
THE FIX. Measure the gap and decide. HA refreshes `sun.sun` every ~4 minutes by
day (verified on the home instance: 08:58:56, 09:02:56, 09:06:56, …), i.e. ≤1°
of elevation per update, so anything from SKY_SNAP_DEG = 3° up can only mean
"we were not watching". Such a step is painted with `transition: none` for a
single frame (`.stage.daynight.skysnap`, released on the next
requestAnimationFrame, so the very next change glides again); everything
smaller keeps the 45 s breathing untouched. `visibilitychange → visible` clears
the marker outright, so a tab that comes back is right immediately.
The elevation the sky is computed from is now rounded to 0.1° (`skyElevation`,
shared by the stage background and the plan dimming) — invisible across a 45 s
glide and it keeps lit from re-committing the style attribute on every hass
tick. The ray GEOMETRY memo is deliberately untouched and keeps its own,
coarser key: the sky is cheap, polygon clipping is not.
Tests: unit — skyNeedsSnap (null/NaN, a real 4-minute step glides, 3° in either
direction jumps), skyElevation. Smoke — demo/smoke_sun_live_bg.mjs, which
asserts the COMPUTED background of the stage (not the style attribute) after a
plain `hass` assignment with no reload and no requestUpdate, plus planDim and
the 3° ray threshold both ways. It fails on the previous tip with
dayComputedWhite, nightComputedDark, backToDayComputed, smallStepMovesSky and
returnFromHiddenSnaps, and it also pins that a REAL sun step still glides
rather than jumps.
Owner, 2026-08-04: «лучи от солнца сделать короче на 30%, проверить, чтобы они
всегда плавно рассеивались (сейчас есть ощущение, что они упираются во что-то
невидимое)».
SHORTER. `rayLength` is now the v1.56 curve times RAY_LENGTH_K = 0.7 — 1.75
window lengths at sunrise, 0.56 at the zenith. Scaling the whole curve instead
of re-picking the constants keeps the shape the owner approved: a low sun still
reaches three times further than a high one.
WHAT THEY WERE BUMPING INTO. Nothing invisible — the wedge's own outline, in
three places at once.
1. The gradient runs ALONG the sun, so its iso-alpha lines are perpendicular to
the sun, while the wedge's far edge is parallel to the WALL. The two
coincide only for a sun hitting the glass dead-on; at any other angle one
half of that far edge was cut while it still carried colour — a straight
bright kerb hanging in the middle of the floor. The single `100% → alpha 0`
stop hid this from the reader of the code and from nobody else.
2. The two SIDES of the wedge had no falloff at all: two razor lines from the
window into the room, brightest exactly where they are most visible.
3. Where the room outline clips the wedge — the opposite wall, the inner corner
of an L, and above all an OPEN (virtual) boundary, which has no wall drawn
at all — the shaft was chopped at whatever alpha it still had.
WHAT IT IS NOW. The gradient still spans the FULL wedge (geometry and gradient
must describe the same shaft), but `rayStops()` eases it to a hard zero at
RAY_FADE_END = 85% of the length, so the last 15% of every wedge is guaranteed
empty and a shaft ending in mid-air has nothing left to draw an edge with. Each
wedge is then drawn inside `<g filter clip-path>`: SVG applies the filter FIRST
and the clip SECOND, so a Gaussian blur of `raySoftness(len)` (7% of the shaft,
clamped 3…18 render units) feathers the sides and the tip and the room outline
cuts that feather off. Light still never crosses a wall — but where it reaches
one, the kerb is a soft ramp that reads as light landing ON the wall.
Clipping by the room is untouched; only its visible edge changed.
Tests: unit — rayLength pinned at exactly 70% of the old curve at ten
elevations, rayStops (monotone, dead at/after 85%, bright at the glass),
raySoftness clamps. Smoke — demo/smoke_sun_soft.mjs, which fails on the
previous tip (lowSunIs70Percent, highSunIs70Percent, gradientSpansWholeWedge,
deadWellBeforeTheEnd, everyWedgeFeathered). Stills: demo/shot_sun_short.mjs.
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.
- 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
Owner: the white backing must hug the ROOMS — an L-shaped house or detached
buildings grew a white square around the plan. Drawn plans now paper one
opaque shape per room (paperRoomShapes in logic.ts) in exactly the room's own
geometry — polygon points / rounded rect verbatim — so the union of the stack
is the paper: islands paint over their parent, open (virtual) boundaries
change nothing, and the scene bg_color / daynight sky reaches the exterior
walls, shows in the L's pocket and between buildings. Image plans keep the
backdrop-image rect (the canvas IS the paper). A live resize preview
(_rszPreview) feeds _renderCfg, so the paper moves WITH a dragged wall.
Static space-card follows the same contract. Paper is fill-only (stroke:none).
smoke_bg_color §11–13 rewritten: L-shaped + detached test rooms, paper-per-
room DOM checks, resize-preview wiring, pixel probes (acid in the pocket and
between buildings, none inside rooms); §13 injects the snapshot directly —
the module-level config-store cache made the old WS mock a no-op. Was 8 red
on the previous build, green now. docs/SUN.md + docs/TESTING.md contract
updated; unit test for paperRoomShapes.
Owner request 2026-08-03: bg_color (and the daynight sky) used to shine
through the plan itself — a hand-drawn plan's translucent room fills sat
directly on the scene colour, and a transparent backdrop image let it
through too. An opaque rect.hp-paper now sits under everything the plan
draws and hugs the plan's extents (the backdrop image rect, or the drawn
content bounds the opening view fits). Its colour is the pre-bg_color
canvas: white for drawn plans (.stage.noplan), the theme card background
under an image and on the static space-card. The daynight night keeps
dimming the plan via the zoomwrap brightness filter ONLY — the paper's
alpha never changes. The scene colour is visible strictly AROUND the
plan, in view/kiosk/editors and the static card alike.
smoke_bg_color grew the contract (sections 11–13): paper presence,
geometry and opacity in view/editors/night, the white drawn-plan paper,
the static card's paper, plus a pixel proof against an acid #ff00ff
background (screenshot → canvas: no acid admixture inside the plan, acid
right outside it). The suite fails on the previous build.
docs: SUN.md background contract + TESTING.md checklist item.
