feat v1.22.0: presence ripples, per-device icon size/rotation, one-click HACS badge

Visuals borrowed from easy-floorplan (github.com/nicosandller/easy-floorplan), model kept ours. isActiveState is independent of the live_states toggle; unavailable/unknown count as idle. Honours prefers-reduced-motion. Badges scale with --dev-size. +1 test (74).

+- **Split** — click a room, then two points on its walls; the chord cuts it in two. The bigger part stays the room it was (name, area, devices); the smaller one asks for a new name and area.

 ### Step 6. Adding your own devices manually

+You can also place a **single entity** (not just a whole device): start typing in the binding search and individual entities appear next to devices — handy when one device exposes several values (e.g. temperature and humidity) and you want each as its own icon.

 Not everything has to be left to the automation. With the **＋** button in the header you can place any device, group or a **virtual point** on the plan (for example, an "Inlet valve" that does not exist as a device).

+- **Объединить** — кликните комнату, затем соседнюю с общей стеной; они сольются в одну. Диалог выбирает, чьё имя и зона останутся.

 Не всё нужно оставлять на автоматику. Кнопкой **＋** в шапке можно поставить на план любое устройство, группу или **виртуальную точку** (например, «Вентиль на вводе», которого нет как устройства). Задайте имя, иконку, модель, ссылку, описание и при желании приложите **PDF-инструкцию**.

+- `src/space-geometry.ts` — pure model/position math (`spaceModels`, `roomBounds`,

+  mirrors the full card's private geometry.
+- `src/space-render.ts` — `renderSpaceStatic()` draws the plan + configured room

 # Changelog

+## v1.22.0 — 2026-07-17 (presence ripples, per-device icon size/rotation, one-click install)
+Ideas borrowed from [easy-floorplan](https://github.com/nicosandller/easy-floorplan) — the visuals,
+not the model.
+- **Presence ripples**: `display: badge | ripple | icon_ripple` per marker, with `ripple_color`
+  and `ripple_size`. Active → pulsing rings; idle → a faint dot. Gated by the pure
+  `isActiveState` — independent of the card-wide live_states toggle, and `unavailable`/`unknown`
+  count as idle so an outage never leaves a ring pulsing. Honours `prefers-reduced-motion`.
+- **Per-device icon `size` (×0.5–3) and `angle`** — sizing now hangs off `--dev-size`, so value
+  badges scale with the device.
+- **One-click install badge** (My Home Assistant → HACS) in both READMEs.
+- (+1 test.)
+
+## v1.21.3 — 2026-07-16 (room labels: no text shadow)
+- Room name labels no longer carry a text shadow — crisper look on both the white
+  hand-drawn canvas and plan images.
+
+## v1.21.2 — 2026-07-16 (space-dialog polish)
+- The **"Scale (cm per cell)" input is compact** again — a generic `width:100%`
+  dialog rule was stretching it across the row.
+- **A space with no background image now gets a white "paper" canvas** instead of
+  the dark stage, so hand-drawn rooms read like a floor plan on paper.
+
+## v1.21.1 — 2026-07-16 (audit: split snaps to the wall, docs for merge/split)
+- **Fix (found in audit):** Split required each click to land on a grid node, so it
+  silently refused rooms whose walls are not grid-aligned (imported or older polygons)
+  — the "pick a wall" toast fired no matter where you clicked. The click now snaps to
+  the room's nearest wall (`closestPointOnBoundary`) instead of the grid, with the pull
+  capped at ~6 grid cells so an accidental click in the middle of a room stays a miss
+  rather than becoming a wall point the user never meant; `splitRoom()` still rejects
+  a cut that is not a clean wall-to-wall chord. Also makes aiming easier on the fine
+  (240-cell) grid.
+- **Docs:** README (en + ru) now documents room Merge, Split, the drawing ruler and the
+  per-space scale — these v1.18–v1.21 features were shipped without user-facing docs.
+  `docs/TESTING.md` gained merge/split rows and a fresh self-run record.
+- New smokes `demo/smoke_merge_split.mjs` and `smoke_split_nonsnap.mjs`;
+  `closestPointOnBoundary` unit-tested. (+1 test: 72 → 73.)
+
+## v1.21.0 — 2026-07-16 (merge and split rooms)
+- **Merge** (toolbar "Merge"): click a room, then a neighbour. Only rooms that **share a wall**
+  can merge — and that is decided by the result rather than a heuristic: `mergeRooms` unions the
+  outlines and accepts the pair only when they collapse into ONE hole-free outline. A corner
+  touch, rooms apart, or a union enclosing a hole are refused. A dialog picks which name and
+  area survive; the kept room keeps its id, so its label position and devices stay put. The
+  dialog warns that the other area is released.
+- **Split** (toolbar "Split"): click the room, then two points on its walls — the chord cuts it
+  in two, with the live ruler on the cut. **The bigger part stays the room it was** (name, area,
+  devices); the smaller becomes a new room and its dialog asks for name/area. Cancelling the
+  dialog leaves the room whole — the cut is applied only on confirm. Cuts that do not run
+  wall-to-wall inside the room (ends off the wall, chord leaving a concave room, a chord along a
+  wall) are refused.
+- Boolean geometry via **polyclip-ts** (proper ESM + native types; `polygon-clipping` ships named
+  types but a default-only ESM build, which breaks either tsc or the runtime). Verified against
+  the real plan, where neighbouring walls overlap collinearly instead of matching exactly —
+  the case a hand-rolled union gets wrong. Bundle: 151 KB → 202 KB.
+- New pure helpers: `polygonArea`, `mergeRooms`, `splitRoom`. (+5 tests: 67 → 72.)
+
+## v1.20.0 — 2026-07-16 (rooms may not overlap)
+- **A click strictly inside an existing room is refused** while drawing (toast names the room).
+  Being *on* a wall stays legal — neighbouring rooms share walls, and real walls overlap
+  collinearly rather than match exactly, so new vertices land on existing outlines mid-span
+  all the time. `pointStrictlyInside` excludes the boundary explicitly (ray casting alone is
+  unreliable exactly on an edge).
+- **Closing an outline that overlaps an existing room is refused** — vertex checks alone are not
+  enough: an outline drawn *around* a room has every vertex outside it. The outline stays open
+  so it can be corrected. Nesting one room inside another counts as an overlap.
+- New pure geometry in logic.ts: `roomPoly`, `pointOnBoundary`, `pointStrictlyInside`,
+  `segmentsProperlyCross` (touching/collinear is deliberately not a crossing), `roomsOverlap`
+  (edge crossings + containment probe, which also catches duplicate outlines). (+4 tests: 63 → 67.)
+
+## v1.19.0 — 2026-07-16 (a line is never a thing of its own)
+**Model change.** A wall can only exist as an edge of a closed room. Consequences:
+- **Walls are derived from room outlines** (`roomEdges` in logic.ts), not stored. A wall
+  shared by two rooms is emitted once, so **deleting a room keeps the borders its neighbours
+  still contribute** — and drops the walls nobody else uses. This falls out of the model
+  instead of needing bookkeeping.
+- **An abandoned outline leaves nothing behind.** Previously every click pair was written to
+  `space.segments` immediately, so a contour you never closed left orphan lines on the plan.
+  Now nothing is persisted until the room is saved.
+- **The "Erase line" tool is gone** — there is no standalone line to erase. Mis-clicks are
+  undone with Esc / Ctrl+Z as before.
+- **`space.segments` is dropped on every save** (legacy configs shed it on first write).
+  Validation still tolerates the field so a stale browser tab cannot fail a save; diagnostics
+  no longer reports it. Lines that belonged to no room disappear on upgrade — by design.
+- Dead code removed: `_addSegment`, `_removeSegmentByKey`, `_distToSeg`, `_pathSegs`, `_segKey`.
+  `segKey(a, b, prec)` gained a precision argument (normalized coords need more than render
+  units). (+2 tests: 61 → 63.)
+
+## v1.18.1 — 2026-07-16 (fix: the drawing ruler was invisible)
+- Fix on top of v1.18.0: the length badge never showed up while drawing. It was rendered
+  inside `.devlayer`, and `.stage.markup .devlayer { display: none }` hides that whole layer
+  in markup mode (so icons do not get in the way) — the badge was in the DOM but invisible.
+  It now lives in its own `.measurelayer` (absolute, `pointer-events: none`), which markup
+  mode does not hide. Verified visually on a real drawn segment ("3.60 m" on screen).
+- Testing lesson (see docs/TESTING.md): asserting on `textContent` is not enough — a DOM
+  query passes on elements hidden by an ancestor. Check `offsetParent`/rect or look at a
+  screenshot.
+
+## v1.18.0 — 2026-07-14 (live measurements while drawing rooms + per-space scale)
+- **Ruler while drawing.** In room-markup "draw" mode, a badge follows the cursor showing the
+  length of the current segment (last placed vertex → cursor). Units come from the HA unit
+  system: metric → metres ("1.25 m"), imperial → feet+inches ("4′ 1″").
+- **Per-space scale.** New "Scale (grid cell size)" field in the space dialog — cm represented
+  by one grid cell (default **5 cm**, i.e. 240 cells ≈ 12 m). Stored as `space.cell_cm`; each
+  plan can have its own real-world size.
+- Pure helpers `segmentCm` / `formatLength` in logic.ts (unit-tested); `_fmtLen` +
+  `_renderMeasureLabel` in the card; `.measurelabel` style; i18n `space.scale_label`/`scale_unit`.
+  (+3 tests: 58 → 61 frontend.)
+
+## v1.17.2 — 2026-07-11 (humidity badge: gate on the sensor, not the icon)
+- Fix on top of v1.17.1: the humidity `%` badge is now shown whenever the marker's primary
+  entity is a humidity sensor (`device_class: humidity`), regardless of the resolved icon.
+  Previously it required the `mdi:water-percent` icon, so a humidity sensor whose name matched
+  another icon rule (e.g. a "Myheat Влажность …" sensor → boiler icon) showed no value.
+  Verified live (45.2 → 45%). (+1 test: 57 → 58.)
+
+## v1.17.1 — 2026-07-11 (humidity value next to the icon, like temperature)
+- **Humidity sensors now show their value (%) next to the icon**, mirroring the temperature
+  badge. Any marker resolved to the humidity icon (`mdi:water-percent`) — a humidity device or a
+  humidity entity placed on its own (v1.17.0) — gets an integer `%` badge and the value in its
+  tooltip. New `isHumEntity`/`humFor` (diagnostic entities excluded), `DevItem.hum`, `.hval`
+  badge, gated by the same "sensor values" option as temperature. (+2 tests: 55 → 57.)
+
+## v1.17.0 — 2026-07-11 (place individual entities, not just whole devices — issue #1)
+- **You can now put a single entity on the plan as its own icon** — e.g. a climate sensor
+  exposes temperature AND humidity; add the device (shows temperature) and separately add the
+  humidity entity as a second icon. In the "add device" dialog, start typing in the binding
+  search and individual entities now appear alongside devices/helpers (surfaced only while
+  searching, so the default list stays clean); the sub-label shows the domain and parent device.
+- Entity markers now get a **sensible auto icon** (name rules → `device_class` → chip) instead of
+  the generic shape, and a **temperature value** when the entity is a thermometer/air-monitor.
+  The `entity:<eid>` binding already existed (used by helpers/light groups); this exposes it for
+  any entity. (+1 test: 54 → 55.)
+
+## v1.16.2 — 2026-07-11 (docs+log: correct card resource URL — fixes "Custom element doesn't exist")
+- **Support issue #2**: users adding a Lovelace resource that points at the on-disk path
+  `/custom_components/houseplan/frontend/houseplan-card.js` get a `text/plain` MIME error and
+  "Custom element doesn't exist: houseplan-card" — HA does not serve `custom_components/` over
+  HTTP. The integration serves the card at **`/houseplan_files/houseplan-card.js`** (verified:
+  `200 text/javascript`) and auto-registers it as a Lovelace resource in storage mode.
+- README (en+ru) now documents the correct URL and the common mistake, incl. a YAML-mode
+  `resources:` snippet.
+- On setup the integration logs (INFO) the exact served URL and, when Lovelace resources are
+  YAML-managed, how to add it manually — so the fix is discoverable from the logs.
+
+## v1.16.1 — 2026-07-08 (space-card shows room fills as configured)
+- **The static `houseplan-space-card` now renders room fills exactly as configured on the
+  full card** (temperature / signal / lights coloring), as a snapshot of the states passed
+  in via `hass` — reverting the v1.16.0 omission. The card still does not subscribe to state
+  changes itself and stays non-interactive (`pointer-events:none`); fills refresh when HA
+  hands the card an updated `hass`. Added shared `areaLqi()` in devices.ts.
+
+## v1.16.0 — 2026-07-08 (new: houseplan-space-card + deep-link)
+- **New second card `custom:houseplan-space-card`** — a READ-ONLY, static schematic of a
+  single space, embeddable on any dashboard. Draws the configured plan + room borders/names +
+  device markers at their saved positions, with **no interactivity** (the schematic layer is
+  `pointer-events:none` — no clicks/hover/tooltips/drag/more-info) and **no live states**
+  (no state subscription, no status/temperature fills). A footer button opens the space in the
+  full component via a **deep-link** (`#space=<id>`). Config: `space` (required), `title`,
+  `show_button`, `button_label`, `button_target`, `aspect_ratio`, `icon_size`; unknown space → a
+  tidy error card. GUI editor with a space dropdown from the integration config.
+- **Deep-link in the full card**: on load it reads `#space=<id>` (valid id wins over
+  `default_floor`) and listens to `hashchange`, without blocking manual space switching.
+- **Shared rendering**: pure geometry in `space-geometry.ts` (unit-tested), the static drawer in
+  `space-render.ts`, and a **module-level config cache** (`config-store.ts`, rev-keyed, seeded from
+  the full card's localStorage snapshot, invalidated on `houseplan_config_updated`) so N embedded
+  cards on one board share a single WS request. Both cards ship in the one bundle.
+- Tests: 48 → 54 frontend (space geometry) + demo smokes `smoke_space_card` and `smoke_deeplink`.
+- Note: status/temperature fills are intentionally omitted from the static card (they are live);
+  it shows configured room borders/names + neutral icons. Marker/position edits reflect after the
+  config event or a reload.
+
+## v1.15.6 — 2026-07-08 (room hover also reveals the border)
+- Hovering a room now **shows its outline** even when borders are turned off. The stroke
+  colour (`--room-stroke`) is now always set to the room colour and only hidden via
+  `--room-stroke-op` — so the existing `stroke-opacity: 1` on hover reveals a crisp border
+  (previously the stroke was `transparent` when borders were off, so hover showed nothing).
+
+## v1.15.5 — 2026-07-08 (fix: room hover was always grey even when filled)
+- Room hover now **darkens the current fill** for filled rooms and only greys **unfilled**
+  ones (as intended since v1.15.1). The legacy `.room.overlay:hover` / `.room.yard:hover`
+  grey rules were still matching styled rooms and, being applied to `fill` directly, beat
+  the `--room-fill` variable — so a temperature/light/zigbee-filled room turned grey on
+  hover. Scoped those legacy rules with `:not(.styled)`; styled rooms are now governed only
+  by `.styled.filled:hover` (brightness 0.78) and `.styled:not(.filled):hover` (grey).
+
+## v1.15.4 — 2026-07-08 (fix: device icon vertical centering — proper root cause)
+- **Root cause of the off-centre icon, found in the live app** (the demo stub hid it):
+  HA's real `<ha-icon>` host is `display:block` with a large inherited `line-height`
+  (~22 px for a ~12 px glyph), so the SVG sat ~1.8 px **below** the badge centre.
+  Fix: `.dev ha-icon` is now a zero-line-height flex box — the glyph centres exactly.
+- Reverted the v1.15.3 `box-sizing: border-box` (it shrank the badge by 2 px and made the
+  vertical offset *more* visible — "worse"). The 1 px anchor drift is instead corrected by
+  the centering margin (`-(size/2 + 1px)`), keeping the original badge size.
+- Verified in the real dashboard: anchor offset 0, glyph offset 0, badge size unchanged.
+- Demo `ha-icon` stub made faithful to HA (block + line-height) so `smoke_icon_center`
+  now actually reproduces and guards this; the smoke also asserts glyph-in-badge centering.
+
+## v1.15.3 — 2026-07-08 (fix: device icon 1px off its anchor point)
+- Device icon badges were sitting **1 px down-and-right of their true point**: `.dev`
+  used the default `content-box`, so the 1 px border made the rendered square 2 px
+  wider than the width the centering margin assumed. Added `box-sizing: border-box` —
+  the badge centre now lands exactly on the device coordinate (verified in the demo:
+  anchor offset 1 px → 0). The glyph itself was already centred within the square.
+
+## v1.15.2 — 2026-07-08 (fix: room average temperature counted non-thermometers)
+- **Average room temperature now uses only devices the card treats as thermometers**
+  (`mdi:thermometer` / `mdi:air-filter`). Previously `areaTemp` swept every device in the
+  area through `tempFor`, so fridges, TRV heads and smart plugs leaked their readings into
+  the average (e.g. a 8.3 °C valve/appliance temperature dragging a room down).
+- **`isTempEntity` now excludes chip/diagnostic temperatures**: `*_device_temperature`
+  sensors and any entity in the `config`/`diagnostic` category are no longer treated as a
+  room temperature — so even a genuine thermometer no longer reports its chip temperature.
+- Affects the temperature room fill and the room tooltip average. (+3 frontend tests: 46 → 48.)
+
+## v1.15.1 — 2026-07-06 (display-settings UX round from live usage)
+- **Comfort-bounds input hardening**: clearing a temperature field can no longer
+  collapse a bound to 0 (`Number('') === 0` — this silently turned "comfort from
+  25" into a 0–25 range after the auto-swap, showing green at 24°). Inputs now
+  parse with `parseFloat` + `isFinite` guard and the save path falls back to the
+  defaults for non-finite values.
+- Room tooltip now shows the **average room temperature** (what the temperature
+  fill actually uses — averages every thermometer in the area, including TRVs).
+- **Hover no longer recolors rooms blue**: filled rooms darken their current fill
+  (`brightness(0.78)`), unfilled rooms get a light grey tint.
+- Fill mode selector is a **radio group** with short labels (no color legend);
+  the comfort bounds sit compactly inline on the temperature row (56 px inputs).
+- The space dialog is wider (500 px) — the settings no longer feel cramped.
+
+## v1.15.0 — 2026-07-06 (temperature room fill)
+- New room fill mode **"Temperature"**: light blue below the comfort range, green
+  inside it, warm yellow above. The comfort bounds (default 20–25 °C) are editable
+  right in the space dialog and appear only when the mode is selected; bounds
+  entered in the wrong order are swapped automatically. A room's temperature is
+  the average of its devices' temperature readings; rooms without a reading stay
+  unfilled. (+`areaTemp` helper, 3 new frontend tests, backend schema fields.)
+
+## v1.14.0 — 2026-07-06 (per-space display settings, hand-drawn spaces, testing checklist)
+- **Per-space "Display" settings** (space dialog): always-visible room borders,
+  room name labels, a border/name color picker with an opacity slider, and a room
+  fill mode — none / by zigbee signal (red→green) / by lights (yellow = something
+  is on, grey = all lights off; rooms without lights stay unfilled).
+- **Room name labels are draggable** like device icons; positions persist server-side
+  (layout keys `rl_<roomId>`), defaults to the room centre; hidden in markup mode.
+- **Hand-drawn spaces**: the space dialog got a "No image — I'll outline rooms by
+  hand" option with a canvas orientation choice (landscape/portrait/square). Such
+  spaces default to visible borders and names; switching an existing space to this
+  mode detaches its background image. The plan image is no longer mandatory.
+- Backend: explicit validation schema for the new per-space settings (+test).
+- **`demo/` harness moved into the repository** (synthetic home, host page, capture
+  and smoke scripts, icon-map generator) — public materials and smoke tests no
+  longer depend on a perishable sandbox.
+- **`docs/TESTING.md`**: a comprehensive manual-testing checklist (environments
+  matrix, every feature, edge cases); policy — updated in the same commit as any
+  functional change. The first self-run found and fixed two bugs:
+  `plan_url` not detached on image→draw switch, and a `_stateClass` crash on
+  state objects without `entity_id`.
+- Tests: 43 frontend + 11 pure backend; new smokes `smoke_space_settings` and
+  `smoke_edge_cases` (empty install, XSS names, legacy layout entries, 150-device perf).
+
+## v1.13.3 — 2026-07-06 (privacy: drop legacy real-house plan sources)
+- Removed the legacy `assets/` directory (real floor-plan sources from the pre-v1.3
+  bundled-data era). Nothing in the build referenced it; instance data lives in
+  server-side config. Note: the files remain in old git history and release archives.

+## Environments matrix
+
+Run the *core flows* (marked ★ below) in each environment at least once per minor release:
+
+- [ ] Chrome / Edge (desktop, Windows or Linux)
+- [ ] Firefox (desktop) — SVG viewBox math and container queries differ historically
+- [ ] Safari (macOS) — pointer events / pinch behavior
+- [ ] HA Companion app, Android (cold start! the v1.7.2 race lived here)
+- [ ] HA Companion app, iOS
+- [ ] Tablet in kiosk/panel mode (wall-tablet scenario, landscape)
+- [ ] Phone portrait, narrow ≤400 px (adaptive header ≤620 px)
+- [ ] Dark theme and light theme (badges, dialogs, plan contrast)
+- [ ] RU profile locale and EN profile locale (+ `language:` card option forcing each)
+
+## Installation / upgrade / removal
+
+- [ ] Fresh install via HACS custom repository → integration appears, card auto-registers as a Lovelace resource (`?v=` matches manifest); no manual resource setup
+- [ ] `single_config_entry`: adding a second entry is impossible [auto]
+- [ ] Upgrade via HACS: `?v=` bumps after HA restart, browser picks the new bundle without cache clearing
+- [ ] YAML-mode Lovelace: falls back to `extra_module_url` (card loads)
+- [ ] Removal: delete entry → Lovelace resource entry disappears; `.storage/houseplan.*` survives; reinstall picks the old config up
+- [ ] Diagnostics download works; personal fields (name/link/description/pdfs) are `**REDACTED**` [auto]
+
+## Onboarding ★
+
+- [ ] Empty config, HA has floors → floors-import wizard offers them sorted by level [auto]
+- [ ] Wizard: uncheck all → "Create" disabled; "Start from scratch" → classic dialog
+- [ ] Wizard: N floors → space dialog per floor with prefilled name and progress "i of N"; Skip skips one; Cancel aborts the whole queue [auto]
+- [ ] After the last wizard space (or first manual space) → markup mode auto-opens with a toast
+- [ ] Empty config, no floors → classic "New space" dialog auto-opens once per session
+- [ ] All floors skipped, nothing created → empty state with "Add space" button remains usable
+
+## Spaces ★
+
+- [ ] Create with an image (SVG, PNG, JPG, WebP) → correct aspect, crisp at zoom (SVG)
+- [ ] Oversized plan (>8 MB) → readable error toast, dialog stays open
+- [ ] Create with "No image — I'll outline rooms by hand": orientation landscape/portrait/square respected [auto]; borders+names default ON [auto]
+- [ ] Draw-space (no background) renders a WHITE canvas (paper-like), markup works on it; room borders/names stay legible on white [auto]
+- [ ] Edit: rename; replace image; **switch image→draw detaches the plan** [auto]
+- [ ] Delete space with rooms/devices → tab disappears, layout of other spaces untouched
+- [ ] Display settings: borders toggle, names toggle, color picker + opacity slider live-preview after save, fill selector [auto]
+- [ ] Fill "zigbee": rooms tint red→green by average LQI; rooms without zigbee stay unfilled [auto]
+- [ ] Fill "lights": yellow when any light on, grey when all off, unfilled when the room has no lights [auto]; toggling a light from the plan recolors the room
+- [ ] Fill "temperature": blue below the comfort range, green inside, yellow above [auto]; comfort bounds editable inline on the radio row (swapped bounds tolerated [auto], clearing a field cannot zero a bound [auto]); rooms without a temperature reading stay unfilled [auto]
+- [ ] Fill mode is a radio group (no dropdown); labels carry no color legend
+- [ ] Room hover darkens the current fill (no recolor to blue); unfilled rooms hover light grey
+- [ ] Room tooltip shows the average room temperature when any thermometer reports [auto]
+- [ ] Average room temperature counts ONLY thermometer/air-monitor devices — fridges, TRV heads,
+      smart-plug chip temperatures (`*_device_temperature`) and diagnostic-category temps are excluded [auto]
+- [ ] Space dialog is 500 px wide; the comfort-bounds inputs are compact (56 px)
+- [ ] The scale (cm per cell) input is compact (72 px), not full-width [auto]
+- [ ] Device icon badge is centred exactly on its point (no 1 px down-right drift) [auto]
+- [ ] Device glyph is centred within its badge (no vertical drift — real ha-icon is block+line-height) [auto]
+- [ ] Room hover highlight still works when custom borders/fills are on
+- [ ] Settings persist across reload and other browsers (server-side)
+
+## Room markup editor ★
+
+- [ ] Grid appears; dots snap; the outline draws pair-by-pair; shared walls reused
+- [ ] Ruler: while drawing, the length of the current segment follows the cursor
+      (metres, or feet+inches on an imperial HA); scale = space "cm per cell" (default 5)
+- [ ] A line cannot exist on its own: start an outline, do NOT close it, leave markup —
+      no lines are left behind (nothing was written to the config)
+- [ ] Deleting a room removes its walls, EXCEPT those shared with a neighbouring room
+      (the neighbour still yields them); deleting the neighbour too removes them as well
+- [ ] There is no "Erase" tool in the markup toolbar (removed in v1.19.0)
+- [ ] Rooms never overlap (v1.20.0): a click strictly inside an existing room is refused with a
+      toast; a click ON a shared wall (including mid-span of a longer neighbour wall) still works
+- [ ] Closing an outline drawn AROUND an existing room is refused; the outline stays open
+- [ ] Merge (v1.21.0): two rooms sharing a wall merge into one; the dialog picks the surviving
+      name/area; rooms touching only at a corner or apart are refused with a toast
+- [ ] Split (v1.21.0): click a room, then two points on its walls — the bigger part keeps the
+      name/area/devices, the smaller opens the new-room dialog; Cancel leaves the room whole
+- [ ] Split: a cut with an end off the wall, or along a wall, is refused with a toast
+- [ ] Split: the click snaps to the nearest wall, so it works on non-grid-aligned rooms
+      (imported/legacy polygons), not only on rooms drawn on the current grid [auto]
+- [ ] Split: a click far from any wall (middle of the room) is a miss with a toast —
+      the wall-snap pull is capped, accidental clicks do not pick a wall [auto]
+- [ ] Esc / Ctrl+Z removes the last dot (and its line); Reset clears the path
+- [ ] Closing the contour (click the first dot, ≥4 points) opens the room dialog
+- [ ] Room dialog: area list shows only unassigned areas; picking an area prefills the name
+- [ ] "No area" room (decorative) requires a name; saves with `area: null`
+- [ ] Cancel in the dialog reopens the contour (last point undone)
+- [ ] Saving a room with an area: area devices appear with icons; positions are fixed into the layout [auto]
+- [ ] Erase tool removes exactly the clicked line; Delete-room removes the polygon after confirm
+- [ ] Device icons hidden during markup; visible again on exit
+
+## Devices on the plan ★
+
+- [ ] Auto devices appear only in rooms bound to their area [auto]
+- [ ] Curation hides bridges/groups/scenes/excluded integrations; 👁 "show all" reveals [auto]
+- [ ] Duplicate "name|area" numbered ("Lamp", "Lamp 2") [auto]
+- [ ] Light groups fold their single lamps; `group_lights=false` unfolds [auto]
+- [ ] Drag anywhere (no edit mode), snaps to grid, persists after reload, per space
+- [ ] ↺ reset restores auto layout after confirm
+- [ ] Temperature badge on thermometers; LQI value under zigbee icons with red→green color
+- [ ] Live states: light on = yellow, open cover/lock/door = orange, unavailable = faded
+- [ ] No devices at all in HA (fresh instance) → plan renders, "0 dev.", no console errors [auto]
+
+## Device dialog (markers) ★
+
+- [ ] Open via info card → Edit; all fields persist (name, icon, model, link, description)
+- [ ] Rebind to another device/entity/helper: search filters; already-placed candidates excluded; old position cleaned up [auto backend]
+- [ ] Virtual device: requires name; room required; renders dashed
+- [ ] Room override moves the icon to the room center
+- [ ] Tap-action override select (default/info/more-info/toggle) saves and applies
+- [ ] PDF/manual upload: ok path; >25 MB → readable error; .exe → bad-ext error [auto backend]; traversal names sanitized [auto backend]
+- [ ] `javascript:` in the link field is not rendered as a clickable link [auto]
+- [ ] Remove: auto device → hidden marker (reappears via dialog "show all"? no — stays hidden until re-added); virtual → gone incl. its layout entry [auto backend]
+
+## Icon rules ★
+
+- [ ] ⬡ opens the editor with current rules (defaults if none saved)
+- [ ] Test field resolves live; add/delete/reorder rows; first match wins [auto]
+- [ ] Invalid regex highlights red and is skipped at runtime (other rules still work) [auto]
+- [ ] Reset to defaults; saving defaults stores nothing (settings key removed) [auto]
+- [ ] Custom rules re-icon existing devices immediately; per-device icon override still wins; lock devices keep mdi:lock [auto]
+- [ ] Rules survive reload; second browser sees them after live-sync
+
+## Tap actions & gestures ★
+
+- [ ] Default: tap → info card; card option `toggle`: tap toggles lights/switches/fans/humidifiers only [auto]
+- [ ] Locks/alarms never toggle, even with per-device override [auto]; covers/valves toggle only with explicit per-device override [auto]
+- [ ] Long-press (600 ms) always opens the info card, also when tap=toggle [auto]
+- [ ] Drag > 3 px cancels both tap and long-press; pinch/pan never triggers taps
+- [ ] `pointercancel` (touch interrupted) does not leave a phantom info card [auto]
+
+## Zoom / pan / labels
+
+- [ ] Wheel zoom at cursor; +/− buttons; fit button resets; badge shows %
+- [ ] Pinch zoom + two-finger pan on touch; one-finger pan when zoomed
+- [ ] Zoom level persists per space (localStorage), restored on reload
+- [ ] Window resize / sidebar collapse refits without distortion
+- [ ] Room name labels: default at room center; dragging moves and persists (server layout, `rl_*`) [auto]; hidden in markup mode
+- [ ] Labels legible on light and dark plans (no text shadow) at min/max zoom
+
+## Multi-client & concurrency ★
+
+- [ ] Two browser tabs: drag in A → position appears in B without reload (live event)
+- [ ] Config edit collision: stale tab saving gets a conflict toast, auto-resyncs, retry works [auto backend]
+- [ ] Point layout updates from two windows don't overwrite each other's icons [auto backend]
+- [ ] `admin_only` ON: non-admin user gets readable "administrators only" errors on every write path
+
+## Edge cases
+
+- [ ] HA instance with zero devices/areas → onboarding works, rooms can be drawn, no crashes [auto]
+- [ ] Space with zero rooms → renders; markup hint visible
+- [ ] Room without area + borders ON → drawn, click does nothing, no area tooltip signal
+- [ ] No zigbee devices anywhere → no LQI badges, lqi fill leaves all rooms unfilled [auto]
+- [ ] 100+ devices in one space → build under ~50 ms [auto], drag stays smooth
+- [ ] Very long device/room names → ellipsis/wrap, no layout explosion
+- [ ] HTML/emoji in names (`<b>xss</b>`, 🚿) → rendered as text, never as markup [auto]
+- [ ] Plan file deleted from disk → Repairs issue appears after config save/restart; re-upload clears it [auto backend]
+- [ ] Corrupted `.storage/houseplan.config` → entry retries (ConfigEntryNotReady), no crash loop [auto backend]
+- [ ] HA restart while a dialog is open → next save gets a clean error/conflict, no data loss
+- [ ] Legacy layout entries (v1 {x,y} without space) are ignored gracefully
+- [ ] Kiosk cold start on mobile app: card defined before dashboard render (resource registration)
+
+## Release regression quickies
+
+- [ ] Browser console has zero errors from houseplan-card.js on: dashboard load, markup, dialogs, zoom
+- [ ] HA log has zero houseplan errors/warnings after restart
+- [ ] `npm test` (frontend), `pytest tests_backend` (pure), CI HA-harness — all green
+- [ ] README screenshots/GIF still match the current UI (synthetic home only)
+
+---
+
+## Last self-run
+
+**v1.21.1 (2026-07-16), full audit of v1.16–v1.21.** All `[auto]` items pass (73 frontend
+tests, 12 backend). New smokes on the synthetic home: `smoke_merge_split` (merge fuses
+adjacent rooms keeping the survivor's id; non-adjacent refused with a toast; split creates
+the new room, cancel keeps the room whole, along-wall cut refused) and `smoke_split_nonsnap`.
+Finding turned into a fix (shipped this release): **Split required the click to land on a grid
+node**, so it silently failed on rooms whose walls are not grid-aligned (imported/legacy
+polygons) — the click now snaps to the nearest wall instead of the grid, and `splitRoom()`
+still rejects a bad cut. README (en+ru) gained the merge/split/ruler/scale documentation it
+was missing. The earlier self-run record follows.
+
+**v1.14.0 (2026-07-06), headless demo harness + unit suites.** All `[auto]` items pass
+(43 frontend tests, 11 pure + 12 HA-harness backend tests, `smoke_space_settings`,
+tap/hold/wizard/rules smokes). Bugs found during the run, fixed in the same release:
+1. Edit dialog: switching an existing space from image to "draw" kept the old
+   background (`plan_url` not detached) — fixed.
+2. `_stateClass` crashed on state objects without `entity_id` (domain is now
+   derived from `d.primary`, which the state was looked up by) — fixed; found by
+   the 150-device perf item of this checklist.
+3. Perf item measured: 162 devices build in ~14 ms, re-render ~1 ms — well within budget.
+4. (earlier rounds) long-press phantom after `pointercancel`; `_saveConfigNow`
+   conflict without resync — fixed in v1.13.2.
+Unchecked boxes above (real browsers/devices, multi-tab live sync, Companion apps)
+require hands on real hardware — they remain for the human pass.
+
+## houseplan-space-card (read-only embedded)
+- [ ] `type: custom:houseplan-space-card, space: <id>` renders the space identical to the full
+      card's plan (background + configured borders/names + room fills + icons), no header/controls [auto]
+- [ ] The schematic is fully non-interactive: click/hover anywhere does nothing — no more-info,
+      no tooltip, no drag (`.hp-static-stage` is pointer-events:none) [auto]
+- [ ] Footer button opens the full component already showing that space (deep-link `#space=<id>`) [auto]
+- [ ] Several cards with different `space` coexist on one board; one shared config WS request
+- [ ] Unknown `space` → tidy error card [auto]
+- [ ] `show_button: false` hides the footer
+- [ ] Full card honours `#space=<id>` on load and on hashchange; invalid id ignored [auto]

Matysh	b706ad4b49	feat v1.21.0: merge and split rooms - Merge: click a room, then a neighbour. Adjacency is decided by the RESULT, not a heuristic: mergeRooms unions the outlines and accepts only when they collapse into one hole-free outline (corner touch / apart / hole => refused). A dialog picks the surviving name+area; the kept room keeps its id so its label and devices stay put. - Split: click the room, then two wall points; the chord cuts it, live ruler on the cut. The bigger part stays the room (name/area/devices), the smaller opens the new-room dialog. The cut is applied only on confirm — Cancel leaves the room whole. - Boolean geometry via polyclip-ts (proper ESM + native types; polygon-clipping ships named types but a default-only ESM build, breaking either tsc or the runtime). Verified on the real plan, where neighbouring walls overlap collinearly rather than match exactly — the case a hand-rolled union gets wrong. Bundle 151->202 KB. +5 tests (72). Verified live: merge of Сауна+с/у -> 4-vertex outline, non-adjacent refused, split preserves area (26667 -> 13333+13333), cancel leaves the room whole.	2026-07-16 08:10:24 +03:00
Matysh	1552bff99a	feat v1.20.0: rooms may not overlap - A click strictly inside an existing room is refused while drawing; a click ON a wall stays legal (neighbours share walls, and real walls overlap collinearly rather than match exactly, so vertices land on existing outlines mid-span constantly). - Closing an outline that overlaps an existing room is refused — vertex checks alone are not enough, an outline drawn AROUND a room has every vertex outside it. Nesting counts as overlap. The outline stays open so it can be corrected. - New pure geometry: roomPoly, pointOnBoundary, pointStrictlyInside, segmentsProperlyCross (touching/collinear deliberately not a crossing), roomsOverlap. +4 tests (67). Verified live: all 15 existing neighbour pairs stay clean (no false positives).	2026-07-16 07:59:01 +03:00
Matysh	65268a7985	feat v1.19.0: a line is never an entity of its own — walls are derived from rooms A wall can only exist as an edge of a closed room: - roomEdges(rooms) derives walls from room outlines, deduping shared ones, so deleting a room keeps the borders its neighbours still contribute and drops the rest — the rule falls out of the model instead of needing bookkeeping. - Nothing is persisted while drawing: an outline you never close leaves no lines behind (previously every click pair was written to space.segments immediately). - The 'Erase line' tool is gone; space.segments is stripped on every save (validation still tolerates it on read so a stale tab cannot fail a save). - Dead code out: _addSegment/_removeSegmentByKey/_distToSeg/_pathSegs/_segKey. Docs (ARCHITECTURE/TESTING/CHANGELOG) updated in the same commit. +2 tests (63).	2026-07-16 07:27:23 +03:00
Matysh	4593d96955	fix v1.18.1: the drawing ruler badge was invisible — .stage.markup hides .devlayer The v1.18.0 measure label was rendered inside .devlayer, which markup mode hides entirely (display:none) so icons don't obstruct drawing. Moved it to its own .measurelayer. Verified visually on a real segment (3.60 m).	2026-07-16 06:53:31 +03:00
Matysh	18a0d279a7	feat v1.18.0: live segment ruler while drawing rooms + per-space scale Validate / hacs (push) Has been cancelled Details Validate / hassfest (push) Has been cancelled Details Validate / frontend (push) Has been cancelled Details Validate / backend (push) Has been cancelled Details - Draw mode shows the current segment length near the cursor (metres or feet+inches per the HA unit system). New pure helpers segmentCm/formatLength (unit-tested). - New per-space 'Scale (grid cell size)' field (space.cell_cm, default 5 cm) so each plan has its own real-world dimensions. i18n en/ru, .measurelabel style. +3 tests (61).	2026-07-14 18:48:56 +03:00
Matysh	6cbf4ece4e	fix v1.17.2: gate the humidity badge on device_class:humidity (primary entity), not the water-percent icon — so a humidity sensor whose name forces another icon (e.g. Myheat) still shows its %. +1 test.

Matysh	498b852e86	feat v1.17.0 (issue #1 ): place individual entities as their own icons (not just whole devices) — binding picker surfaces entities while searching; entity markers get an auto icon (name/device_class) + temperature. +1 test.	2026-07-11 14:53:40 +03:00
Matysh	fabeab81aa	docs+log v1.16.2 (issue #2 ): document correct card resource URL /houseplan_files/houseplan-card.js and warn against the /custom_components/... on-disk path (text/plain → 'Custom element doesn't exist'); integration logs the served URL + YAML-mode manual-add hint.

Matysh	fbd3887e14	feat v1.15.6: room hover also reveals the border — keep stroke colour, hide via --room-stroke-op, so hover's stroke-opacity:1 shows the outline even when borders are off	2026-07-08 18:13:23 +03:00
Matysh	5f9cfb9e10	fix v1.15.5: room hover darkens the fill instead of always grey — scope legacy overlay/yard hover with :not(.styled) so filled rooms use brightness(0.78), unfilled stay grey	2026-07-08 17:56:48 +03:00
Matysh	cc27a6b2fa	fix v1.15.4: device icon glyph centering — real ha-icon is block+line-height (glyph sat ~1.8px low); .dev ha-icon now zero-line-height flex.
