 # Changelog
 
+## v1.56.0 — 2026-08-03
+
+Minor release: the sun comes to the floor plan — a compass, a day/night
+backdrop and real sunlight through the windows — plus room temperature
+from climate devices, a design-token pass over the UI, live rulers for
+opening drags, and a sun-cache fix.
+
+- **The sun on your floor plan** (docs/SUN.md). Tell the plan where
+  north is — a compass dial in the general settings, with a per-space
+  override — and the card starts living by Home Assistant's own
+  `sun.sun`:
+  - *Day/night backdrop* (`bg_mode: daynight`): the scene behind the
+    plan follows the sun's elevation — white at full day, warm gold
+    through the golden hour, cooling dusk, deep night. The plan itself
+    dims only ~10% at night, so the rooms stay readable.
+  - *Light through the windows* (`sun_rays`): every window on an
+    exterior wall casts a soft wedge of light into its room — clipped
+    by the room's own contour, warmer near the horizon, stretching
+    long at sunrise and sunset, short at noon, gone after dark.
+  - *Clouds, if you want them* (`weather_entity`): point at a weather
+    entity and an overcast sky mutes the wedges; rain or snow puts
+    them out. A dead sensor never kills the sun.
+  - The plan now sits on an *opaque sheet of paper* traced along the
+    room contours: the scene background — `bg_color` or the daynight
+    sky — is visible only around the walls and never bleeds through
+    the rooms; in day/night mode the sheet casts a soft shadow.
+  - The whole feature is silent until the compass is set; without
+    `sun.sun` the settings dialog explains why.
+- **Room temperature from climate devices.** A new checkbox in the
+  device dialog puts the AC's or thermostat's `current_temperature` on
+  the badge next to its icon and into the room's average temperature.
+- **UI modernization.** A design-token pass over `styles.ts` — 209
+  hard-coded values unified into spacing/radius/font/shadow scales —
+  and native `ha-switch` / `ha-slider` controls in the dialogs, with a
+  hard fallback to the old plain inputs where HA components are
+  unavailable.
+- **Live rulers for opening drags.** Dragging a door or window now
+  shows the live distances to both ends of its wall, measured along
+  the owning room's edge; a dashed guide and a soft magnet snap the
+  opening to the wall's center (hold Shift to disable the magnet).
+- **Fix DEV-B701-01** — the sun-ray cache is now invalidated by local
+  geometry edits too, so a wedge can no longer go stale after you move
+  a wall locally before the server confirms the change.

+## v1.56.0 — 2026-08-03
+
+Минорный релиз: на план приходит солнце — компас, фон «день/ночь» и
+настоящий свет из окон — плюс температура с климатических устройств,
+дизайн-токены в UI, живые линейки при перетаскивании проёмов и фикс
+кэша солнечных лучей.
+
+- **Солнце на плане дома** (docs/SUN.md). Скажите плану, где север —
+  круговой компас в общих настройках с переопределением в каждом
+  пространстве — и карточка начинает жить по `sun.sun` самого
+  Home Assistant:
+  - *Фон «день/ночь»* (`bg_mode: daynight`): сцена за планом следует
+    за высотой солнца — белый ясный день, тёплое золото золотого
+    часа, остывающие сумерки, глубокая ночь. Сам план ночью
+    приглушается лишь на ~10%, комнаты остаются читаемыми.
+  - *Свет из окон* (`sun_rays`): каждое окно на внешней стене пускает
+    в свою комнату мягкий клин света — обрезанный контуром комнаты,
+    теплее у горизонта, длинный на рассвете и закате, короткий в
+    полдень и гаснущий ночью.
+  - *Облачность — по желанию* (`weather_entity`): укажите
+    weather-сущность, и пасмурное небо приглушит клинья, а дождь или
+    снег погасит совсем. Мёртвый датчик солнце не выключает.
+  - План теперь лежит на *непрозрачном листе бумаги*, повторяющем
+    контуры комнат: фон сцены — `bg_color` или небо «дня/ночи» —
+    виден только вокруг стен и не просвечивает сквозь комнаты; в
+    режиме «день/ночь» у листа мягкая тень.
+  - Пока компас не задан, фича полностью молчит; без `sun.sun`
+    диалог настроек объясняет, почему.
+- **Температура с климатических устройств.** Новый чекбокс в диалоге
+  устройства выводит `current_temperature` кондиционера или
+  термостата на плашку у значка и учитывает её в средней температуре
+  комнаты.
+- **Модернизация UI.** Токен-проход по `styles.ts` — 209 «зашитых»
+  значений сведены в шкалы отступов/радиусов/шрифтов/теней — и
+  родные `ha-switch` / `ha-slider` в диалогах с жёстким фолбэком на
+  старые инпуты там, где компоненты HA недоступны.
+- **Живые линейки проёмов.** При перетаскивании двери или окна теперь
+  видны живые расстояния до обоих концов стены — по ребру своей
+  комнаты; пунктирная направляющая и мягкий магнит центрируют проём
+  на стене (Shift отключает магнит).
+- **Фикс DEV-B701-01** — кэш солнечных лучей теперь сбрасывается и
+  локальными правками геометрии: клин больше не «застревает», если
+  подвинуть стену до подтверждения сервера.

 | Item | State |
 |---|---|
-| Version | **v1.55.3** everywhere (manifest, const.py, package.json, CARD_VERSION); deployed to the home instance. Closes the v1.55.2 audit findings AUD-1552-01/02 (boot-veil lifecycle: reconnect restart + full protective window with trailing quiescence + post-reveal soft grace; regressions in `demo/smoke_preloader_lifecycle.mjs`) |
+| Version | **v1.56.0** everywhere (manifest, const.py, package.json, CARD_VERSION); deployed to the home instance. Minor release: the Sun feature (docs/SUN.md — north compass, day/night backdrop, window light wedges, optional weather cloud cover, opaque room-contour paper), opt-in room temperature from climate devices, design-token pass over styles.ts + native ha-switch/ha-slider, opening-drag shoulder rulers with a center magnet, and the DEV-B701-01 sun-ray cache fix |
 | Workflow | Since 2026-07-22: minor changes go to branch **`dev`** (build + smokes → deploy home → commit → push, NO release); releases are batched on the owner's command (merge dev→main, one tag, one release with a summary changelog, CI checked on dev beforehand) |
 | GitHub | https://github.com/Matysh/houseplan-card — **`main` carries every published release, the latest tag is the current version above**; `dev` is where work lands and is merged into `main` at release time (so `dev` is normally equal to or ahead of `main`, never behind). Push via SSH key `ha_jb` (remote git@github.com:…); API releases via the fine-grained PAT in `~/.git-credentials` (Contents R/W, issued 2026-07-23) |
 | CI | validate.yml (hacs + hassfest + frontend + backend) green; release.yml attaches the bundle on release publish |
 | HACS | Custom repository works. **Inclusion PR: hacs/default#9004** — open, valid, labeled, mergeable clean, never drafted. Queue: 1212 open, 835 older than ours. Merge rate COLLAPSED: 75 in July but almost all in the first decade, 0 in the last week (checked 2026-07-29) — maintainers process in rare bursts; ETA unknowable, months at best. Nothing actionable on our side |
-| Home instance | ha.jbstudio.pro (SSH port **22222**, key `ha_jb`; HA config root is `/mnt/data/supervisor/homeassistant` — `/config` does NOT exist in this SSH environment), deployed **v1.55.3** via direct copy (HACS custom repo also installed) |

 | Localization | UI en/ru (src/i18n/*.json), everything user-visible localized incl. kiosk popover |
 | Tests | Four layers: frontend unit (`npm test`, node:test over `test-build/`), pure backend (`pytest tests_backend`, runs anywhere), HA-harness backend (same folder, CI only — needs py3.13 + pytest-homeassistant-custom-component), and browser smokes (`demo/smoke_*.mjs`, headless chromium). **Counts are not written down here** — they went stale within two releases while the version line beside them was kept current, which reads as less coverage than exists (review R5-2). Run `npm run inventory` for the current numbers, or read them off the last CI run |
 | Vacuums | Live robot vacuums shipped (docs/VACUUM.md): puck, server-side trails with display modes, fit-panel calibration. Verified on a live Dreame X50 Master |

+Status: approved by the owner 2026-08-03. Shipped in v1.56.0.
 Scope decisions final: the compass lives in the GENERAL settings with a
 per-space override, the feature is silent until `north_deg` is set
 anywhere, wedges ship for the FULL card only in v1, and mutual shading
