+
+House Plan is one HACS package with two parts plus a demo harness:
+
+- **Lovelace card** (`src/`, TypeScript + Lit) — the primary product, bundled to `dist/houseplan-card.js`.
+- **Storage integration** (`custom_components/houseplan/`, Python) — the Home Assistant backend.
+- **Demo harness** (`demo/`) — a self-contained Playwright page (`demo/srv/demo.html`) that renders the card against a fake `hass`, used for screenshots and the `smoke_*.mjs` end-to-end suite.
+
+Standard commands live in `package.json` scripts, `CONTRIBUTING.md`, and `docs/DEVELOPMENT.md`. Read `docs/ARCHITECTURE.md` and `docs/STATUS.md` before non-trivial changes.
+
+## Cursor Cloud specific instructions
+
+The startup update script already runs `npm ci`, provisions a Python 3.13 backend venv at `.venv-backend`, and installs Playwright Chromium. You do not need to reinstall dependencies.
+
+- **Frontend** (from repo root): `npm run typecheck`, `npm test` (node:test, 424 tests at v1.60.0), `npm run build`. After building, keep both committed snapshots in sync — `cp dist/houseplan-card.js custom_components/houseplan/frontend/` and `cp dist/houseplan-card.js demo/srv/assets/`. CI enforces both comparisons byte-for-byte.
+- **Backend HA-harness tests need Python 3.13, not the system 3.12.** Run them with the venv: `.venv-backend/bin/python -m pytest tests_backend/ -q` (150 tests at v1.60.0: 100 pure + 50 HA harness). Running `python3 -m pytest tests_backend` without Home Assistant silently **skips** the `test_ha_*.py` harness tests (`conftest.py` ignores them when `homeassistant` is not importable) and runs only the pure set.
+- **Running the app / smoke suite**: build a fresh bundle and copy it into the demo assets first — `npm run build && cp dist/houseplan-card.js demo/srv/assets/houseplan-card.js` — then run `node demo/smoke_*.mjs`. The committed demo snapshot must remain byte-identical to `dist` (CI checks it); rebuilding first also guarantees the browser suite tests the current source in an uncommitted worktree. No real Home Assistant server is required: `demo/srv/demo.html` stubs `hass`, registries and `callService`.
+- **Demo harness render quirk**: the fake `hass` in `demo.html` is set once, so opening the page directly in a browser renders the floor plan but **device icons only appear after a re-render** (an F5 refresh, or nudging `card.hass = {...card.hass}`). The smoke launcher `demo/serve.mjs` already does this nudge; a plain browser session does not. This is a harness limitation, not a card bug.
+- **Known environment-sensitive smoke**: `demo/smoke_opening_measure.mjs` fails two sub-checks (`place_dialog_x_magnetised`, `place_committed_x_center`) under the pinned Chromium — a `1e-6`-tolerance magnet-snap on the opening-*placement* path. It reproduces against the pristine committed bundle, so treat it as pre-existing/pixel-precision, not a regression you introduced.
+- **Owner's local Windows checkout is invisible here.** Path
+  `C:\Users\Sergey\Downloads\dev\houseplan-dev` (workflow notes + often
+  unpushed edits) is **not mounted** into managed Cloud Agent VMs. Do not
+  expect to `ls` or diff that folder. To bring local work into the cloud
+  agent: push a branch to GitHub and say its name, or run a **local** Cursor
+  Agent / My Machines worker inside that checkout. Day-to-day source of truth
+  for cloud sessions remains **`origin/dev`** (minors) and **`origin/main`**
+  (releases) — see `docs/STATUS.md`.

+  past: draw and place devices anywhere, pan at any zoom, zoom out to see
+  everything, and let one tap fit the whole plan back on screen.

+  virtual walls and a visual decor layer, all drawn with clicks; room resize
+  by dragging walls, with live lengths and areas as you drag; smart
   alignment guides and a live ruler in real meters/feet.
+- 🖼 **A backdrop you can move and scale** — drag the floor-plan picture into
+  place and pull a corner to size it, with its real size in metres shown as
+  you drag, so the drawing and the photo of your plan finally line up.
 - 💡 **Lights toggle on click** out of the box; wall-switch markers can control
   whole groups of lights (works for dumb switches and stateless remotes too).
 - 🌒 **“Light sources” fill** — a dark house where every lit lamp casts a pool
   of its own color that spills through doorways and open zone boundaries.
+- ☀️ **The sun on the plan** — set the compass and the backdrop lives with
+  the day (white noon → golden hour → deep night), while windows on exterior
+  walls cast real wedges of sunlight into the rooms; optional cloud cover
+  from a weather entity.
+- 🪟 **Curtains and blinds open on a tap** — one action opens, closes or
+  stops a cover, and the icon itself morphs between open and closed while a
+  soft ring pulses as it travels.
 - 🌡 **Room cards** with temperature, humidity, Zigbee LQI and light count;
   comfort-range temperature fills, per-room signal heatmap.
 - 🚪 **Doors, windows and locks** with contact sensors — unlocking is always an
   explicit button, never an accidental tap.
 - 📺 **Kiosk mode** for wall tablets and TVs: fullscreen, swipe between floors,
   auto-carousel, per-screen icon sizes.
+- 🤖 **Live robot vacuums** — the dock marker stays put while a round puck
+  drives the plan in real time, pouring its path out from under itself;
+  current and previous cleanup runs are recorded server-side. Calibration is
+  one click (rooms matched by name) or a drag-and-stretch overlay. Works with
+  Xiaomi Cloud Map Extractor, Tasshack dreame-vacuum and Valetudo.

   Icon colors follow one principle — **yellow means the device is doing its main job right now**:
-  a light is shining, a socket is powering, a fan is spinning, media is playing, a vacuum is

+  a light is shining, a socket is powering, a fan is spinning, a vacuum is

+  a reported work action is authoritative; when an integration exposes only its enabled HVAC mode,
+  that mode is the best available fallback. Orange = open / unlocked.
   A pulsing red ring = an emergency (leak, smoke, gas). An RGB bulb's colour lives in its glow
   spot (glow fill), where the spot itself is the on/off indicator and the badge stays standard.
   A translucent icon = unavailable. Dark = idle.

   Цвета значков подчиняются одному принципу — **жёлтый значит «устройство прямо сейчас выполняет свою основную работу»**:
-  лампа светит, розетка подаёт, вентилятор крутится, медиа играет, пылесос убирает, термоголовка
-  реально греет (а не просто включена). Оранжевый = открыто / не заперто. Пульсирующее красное
+  лампа светит, розетка подаёт, вентилятор крутится, пылесос убирает, термоголовка
+  реально греет (а не просто включена). Для climate-сущностей переданное действие приоритетно;
+  если интеграция сообщает только включённый HVAC-режим, он служит лучшим доступным приближением.
+  Оранжевый = открыто / не заперто. Пульсирующее красное
   кольцо = авария (протечка, дым, газ). Цвет RGB-лампы живёт в её пятне света (режим glow),
   где само пятно — индикатор включения, а подложка значка остаётся стандартной.
   Полупрозрачный значок = недоступно. Тёмный = покой.
+- **Единый визуальный редактор подложки.** Линии, фигуры, надписи и мебель используют общее выделение, физические стили и Undo/Redo. Картинка плана не прибита к холсту: отдельный инструмент двигает, масштабирует и поворачивает её, а числовой диалог задаёт точный размер и угол.
 - **Чёткий зум.** Приближение не «мылит» картинку: план, подписи и иконки остаются векторно-чёткими на любом масштабе.

+//    but kept its truthy id, so the reconnect never restarted the watcher and

+//    connectedCallback: the veil must lift no later than the hard cap.
+// B. layout shifts before, between and after the old poll ticks (150, 300,
+//    450, 590 ms). v1.55.2 revealed the plan after two equal reads at
+//    200/400 ms, so a panel landing at 450+ ms jumped on a VISIBLE plan. Now
+//    the veil holds for the full protective window with trailing quiescence:
+//    not a single frame may show the plan at a non-final stage height.
+// C. a shift AFTER the reveal (slower than the cap) must glide, not snap:

+// не надо размывать их боковые грани». A shaft of sunlight has HARD sides; it
+// fades only with distance, along the ray, from the glass inward. So:
+//   * the reach is still 70 % of the v1.56 curve;
+//   * the gradient still spans the FULL wedge and is dead from RAY_FADE_END;
+//   * the sides are SHARP — no blur filter on the wedge, none defined at all;
+//   * and because the sides are sharp, the wedge must end ON an iso-alpha line
+//     of that gradient: nothing is ever drawn past its end, so the old bright
+//     kerb (a far edge parallel to the wall, cut while still lit) cannot come
+//     back at an oblique sun.
+// DEV-EB173-01 turned the last of those into a contract of its own: the fade
+// runs along the wall's INWARD NORMAL, not along the ray. For parallel rays
+// the distance travelled from the glass is an affine function of the point, so
+// its iso-alpha lines are parallel to the WALL — which is where an honest
+// parallelogram puts its far edge. All three invariants then hold at once:
+// peak alpha across the whole pane, the same fade distance along every ray,
+// and a far edge exactly on the gradient's end. The auditor's own grazing
+// repro is re-run below with his numbers.
+// The "light never crosses a wall" clip is asserted in demo/smoke_sun.mjs
+// (wedgeClippedToRoom) — the polygons arrive from computeSunRays() already
+// intersected with the room, which is why no clip-path is needed here.
