 Thanks for your interest! The project is one HACS package: a storage **integration**
 (`custom_components/houseplan/`, Python) and a **Lovelace card** (`src/`, TypeScript + Lit).
 
+## Changelog
+
+User-visible changes go into **both** changelogs in the same commit:
+`docs/CHANGELOG.md` (English) and `docs/CHANGELOG.ru.md` (Russian). Entries
+older than v1.42.0 exist only in the English file — no need to backfill them.
+
+## Where to ask
+
+Not sure whether something is a bug, or just want to discuss an idea before
+writing code? The **[Telegram chat @ha_houseplan](https://t.me/ha_houseplan)**
+is the quickest route to the author and other users. Bugs and concrete feature
+requests still belong in [issues](https://github.com/Matysh/houseplan-card/issues).

+**User content is served inert** (HP-1454-01). An uploaded SVG is the only
+thing here that a browser will happily treat as a *document* rather than an
+image, and it would be a document of Home Assistant's own origin. Inside the
+card that never matters — `<image>` does not run scripts — but the url is
+reachable directly, and uploading needs only write access, which by default
+every user has. `HouseplanContentView` therefore sends a `sandbox` CSP with SVG
+and only with SVG: a CSP on a PDF response can break the browser's built-in
+viewer, and a raster image has no execution model to disable.
+
+**Attachments follow the same commit-scoped lifecycle as plans** (HP-1454-02).
+An upload takes a free name (`unique_filename`) and never overwrites, because
+the bytes under an existing name may be referenced by the stored configuration
+and an upload is not part of that transaction. A new icon has no id yet, so its
+files go to a per-dialog staging folder and move to the real id once the config
+write is accepted — the same copy → save → cleanup order as a rebind.
+`config/set` collects what its commit superseded, and anything unreferenced and
+older than `PLAN_ORPHAN_TTL_S`.
+
+**Config writes are serialized** (HP-1454-03). `_writeConfig()` chains onto a
+single promise: one `config/set` in flight, each carrying the revision the
+previous one returned. The debounce still spaces out *when* a write starts;
+what it cannot do — and used to be relied on for — is keep two writes from
+overlapping, which produced a self-inflicted conflict and lost the newer edit.
+
+**Plan uploads are copy-on-write, and collection belongs to the commit**
+(reviews R2-1, R3-1). The file system is not part of the config's
+optimistic-locking transaction, so nothing referenced may be overwritten or
+deleted before the CAS succeeds: the upload writes a new versioned name and
+removes nothing. Deciding what may then go is *not* a client's call — a cleanup
+request cannot be ordered against another client's commit, and a delayed one
+deletes a plan that was just saved. So `config/set` collects itself, inside its
+write lock, from the pair of configurations that bracket the commit
+(`plans.collect_plans`): superseded files go immediately, other unreferenced
+uploads only once `PLAN_ORPHAN_TTL_S` has passed, since a fresh one may belong
+to a transaction still in flight. The `.` between id and token is load-bearing —
+a space id cannot contain one, so `<space>.<token>.<ext>` can never be confused
+with the files of a space whose name merely starts the same way.
+
+**Signed content urls are batched, aged and deduplicated** (reviews R2-2, R3-2, R4-2). `ContentSigner`
+in `src/signing.ts` is the single implementation, used by both cards; the
+duplicate inside houseplan-space-card signed correctly and never handed the
+result to its renderer, which is the failure mode a second copy invites. `MAX_SIGN_PATHS`
+(200) is a shared contract between `logic.ts` and `const.py`: the backend caps a
+request there and says nothing about the rest, so the card must chunk. Cached
+signatures carry the time they were issued — an aging one keeps rendering while
+its replacement is fetched, an expired one is dropped rather than served (it
+would 401 and raise a failed-login warning). The cache is pruned to the urls the
+live config references, so it cannot grow past the cap through history alone.
+Queued and in-flight are distinct states: a render happening while a request is
+out must not queue the same url again, a failure backs off rather than retrying
+on the next frame, and an in-flight entry expires after `SIGN_INFLIGHT_MS` so a
+promise that never settles cannot block retries forever.
+
+**Room climate is one pass per hass snapshot** (review R2-3). `areaClimateMap()`
+classifies the whole registry once and returns `Map<area, {temp, hum}>`; the
+card memoizes it on `hass` identity, which Home Assistant replaces on every
+state change. Per-room lookups are O(1). `areaClimate()` survives as a
+single-area wrapper for tests — using it in a render reintroduces the
+O(rooms × entities) cost it was extracted from.
+
 **File uploads go over HTTP** (not WS, which has a message-size limit): `POST /api/houseplan/upload`
 (multipart: marker_id + file), HomeAssistantView, requires_auth. Served from `/houseplan_files/files/`.

+## Audit follow-ups (2026-07-27)
+
+- **Content is authenticated.** `/houseplan_files/…` now serves ONLY the card
+  bundle (a Lovelace resource must be public). Plans and marker files go
+  through `HouseplanContentView` (`/api/houseplan/content/<plans|files>/…`,
+  `requires_auth`). `contentUrl()` rewrites legacy stored URLs on read, so no
+  storage migration is needed. Static paths cannot be unregistered — the old
+  routes survive until the next HA restart.
+- **Optimistic UI, stated explicitly (audit L7).** `_serverCfg` is mutated in
+  place before a fallible save in ~22 places and there is no rollback: after a
+  rejected save the UI shows the edit until the next reload. This is a
+  deliberate optimistic-UI choice, not drift. Paths where it is unacceptable
+  need their own rollback.
+- **Split invariant.** `splitRoomPath` guarantees a partition: the two parts'
+  areas sum to the original (within epsilon) or the cut is rejected.

 # Changelog
 
+## v1.46.0 — 2026-07-28 (full external audit of v1.45.4: HP-1454-01 … -10)
+
+**Security**
+
+- **An uploaded SVG plan is no longer a live document of your Home Assistant
+  origin (HP-1454-01, high — release blocker).** Inside the card a plan is
+  referenced by `<image>`, where scripts never run; but the same url opened
+  directly became a top-level document of HA's own origin, and a `<script>` in
+  it could read the session's `localStorage` and call the API. Uploading needs
+  write access, which by default every authenticated user has, and a signed url
+  is easy to hand to an administrator. Plan responses for SVG now carry a
+  `sandbox` Content-Security-Policy, which drops the document into an opaque
+  origin. Only SVG gets it — a CSP on a PDF can break the browser's built-in
+  viewer, and a raster image cannot execute anything. Nothing changes for
+  existing plans: the card renders them exactly as before.
+
+**Data integrity**
+
+- **A manual attached to a device no longer overwrites the previous one
+  (HP-1454-02).** The upload wrote straight to `<marker>/<filename>`, outside
+  the configuration transaction: cancelling the dialog, or a rejected save, left
+  the stored url serving the new bytes. And every new icon uploaded into one
+  shared folder, so two of them attaching `manual.pdf` ended up pointing at the
+  same physical file. Uploads now take a free name and never overwrite, a new
+  icon gets its own staging folder whose files move to the real icon when the
+  save is accepted, and an upload nobody saved is collected an hour later. The
+  name a collision falls back to changed from `manual (2).pdf` to `manual-2.pdf`
+  — the old one was sanitised on the way back in, so a renamed attachment was
+  written and then never served (found by the new test, and it applied to
+  rebind collisions before this release too).
+- **Two quick edits can no longer lose the second one (HP-1454-03).** The
+  debounce spaced out the starts of a save, not the saves themselves. If one
+  took longer than half a second — a busy instance, a slow link — the next edit
+  went out with the same revision, the server accepted the first and rejected
+  the second, and the conflict handler reloaded the server copy over the local
+  one. The edit was gone, with a message blaming another window when there was
+  none. Writes are now serialized: one at a time, each carrying the revision the
+  previous one returned.
+
+**Correctness and limits**
+
+- **Open boundaries follow the geometry again (HP-1454-04).** Their cache was
+  keyed on room ids and links only, so changing a space's aspect ratio or
+  dragging a vertex left the open boundaries — and the light spilling through
+  them — at their old coordinates until a reload. The cache is now keyed on the
+  rendered model itself, which is exactly what it is computed from.
+- **The configuration can no longer be made arbitrarily heavy (HP-1454-05).**
+  The outer collections were capped; the ones inside them were not. A polygon
+  with 150 000 points, or a list of 100 000 device ids, validated fine and then
+  made every render walk it. There are now limits on polygon vertices, open-to
+  links, controls, attachments, text and url lengths, plus a cap on the whole
+  serialized configuration. The obsolete `segments` field is dropped by the
+  server instead of trusting the card to strip it.
+- **Large files stream instead of being held in memory (HP-1454-06).** A 50 MB
+  manual was read whole into memory on the way in and again on the way out; a
+  couple of parallel downloads were real pressure on a small Home Assistant
+  host. Uploads stream to a temporary file, downloads stream from disk.
+
+**Consistency**
+
+- **The static space card honours per-room fill settings (HP-1454-07).** It
+  builds its model with a different function, and room settings were not carried
+  into it, so a room you had set to "no fill" was still painted.
+- **Moving an icon updates the static card immediately (HP-1454-08).** Layout is
+  separate state with no revision and no event: a drag on the full card left a
+  static card next to it showing the old position until the configuration
+  changed or the page was reloaded. Layout writes now keep a revision, return
+  it, and announce themselves — which also makes the optimistic locking on a
+  wholesale layout write mean something, since a point-wise write used to reset
+  the counter.
+- **A repair warning about a missing plan disappears with its space
+  (HP-1454-09).** The cleanup only looked at spaces that still exist, so
+  deleting or renaming one left its warning in Repairs with nothing able to
+  clear it.
+- Build chain: `serialize-javascript` pinned past two advisories (HP-1454-10).
+  Not reachable at runtime and production dependencies were already clean, but
+  it is one line.
+
+## v1.45.4 — 2026-07-28 (review of v1.45.3: R5-1, R5-2)
+- **A partly successful signing answer no longer skips the backoff (R5-1).**
+  The backend signs each path independently: one it cannot sign is logged,
+  skipped, and the call still succeeds with the remaining urls. The card took
+  any successful call as "the whole batch is done", cleared the backoff for
+  every path in it, and then wrote only the urls that came back — so a path the
+  backend kept skipping was requested again on every single render, which is
+  exactly the amplification v1.45.2 added the backoff to prevent. A path is now
+  counted as signed only if the answer actually carries a url for it; the rest
+  back off individually, keys nobody asked for are ignored, and a re-render is
+  only triggered when at least one new signature arrived.
+- **The status snapshot no longer contradicts the repository (R5-2).** It still
+  described `main` as carrying releases up to v1.40.1 and quoted test counts
+  from several releases back, while the version line right beside them was kept
+  current — a maintainer or an agent reading it for handoff got a wrong branch
+  model and a smaller picture of the coverage than exists. The branch roles are
+  described accurately, and the counts are gone: `npm run inventory` prints them
+  from the tree, so there is nothing left to go stale.
+
+## v1.45.3 — 2026-07-27
+- **"Value instead of an icon" could not be saved (issue #3).** The option was
+  added to the device editor in v1.26.0, but the server-side schema only ever
+  accepted `badge`, `ripple` and `icon_ripple`. Choosing it produced
+  `not a valid value for dictionary value @ data['config']['markers'][n]['display']`
+  — and because a single rejected marker fails the whole configuration write,
+  the plan could not be saved at all until the setting was undone. Thanks to
+  @RemyRoux for the report and the exact error text.
+- **The option lists now live in one place and are checked across languages.**
+  `DISPLAY_MODES`, `TAP_ACTIONS`, `SPACE_FILL_MODES` and `ROOM_FILL_MODES` are
+  exported from the card and read by a backend test that asserts the schema
+  accepts every value a user can actually pick. Adding an option to an editor
+  and forgetting the schema now fails the test suite instead of surfacing
+  through somebody's error message.
+
+## v1.45.2 — 2026-07-27 (hardening from the v1.45.1 review: R4-1, R4-2)
+- **A failed cleanup no longer reports an accepted save as an error (R4-1).**
+  Collecting superseded plan files runs after the configuration is already
+  stored, but an error while listing the directory — it can vanish or turn
+  unreadable between the check and the walk — propagated out of `config/set`.
+  The client then saw a failure for a revision the server had committed, and its
+  retry came back as a conflict. The collector now reports "nothing collected"
+  instead of raising, and `config/set` logs and proceeds: the event fires and
+  the new revision is returned.
+- **One signing request per url instead of one per render (R4-2).** The pending
+  set was cleared when the batch went out rather than when it came back, so
+  while a `content/sign` call was in flight every re-render queued another one —
+  six calls where one was needed, and far worse on a socket that is slow rather
+  than merely busy. Queued and in-flight are now separate states, a failure
+  backs off (2 s doubling to 60 s) instead of retrying on the next frame, and a
+  request that never settles stops blocking retries after 15 s. A late answer
+  arriving after the card was torn down no longer triggers a render.
+- Tests: eight unit tests for the signer with hand-settled promises (four fail
+  on v1.45.1), a backend test asserting a broken collector still yields a
+  successful save with a usable revision, and the pure-collector test extended
+  to a disappearing directory.
+
+## v1.45.1 — 2026-07-27 (follow-up review of v1.45.0: R3-1, R3-2)
+- **Collecting old plan files moved into the config transaction (R3-1, high).**
+  v1.45.0 made the upload safe but handed the deletion to the client: after a
+  successful save the card asked the backend to remove everything except the
+  file it had just committed. Two open editors could not be ordered — a delayed
+  request from one client deleted the plan the other had just saved, and the
+  accepted configuration was left pointing at nothing, which is the exact damage
+  copy-on-write was added to prevent. The `houseplan/plan/cleanup` command is
+  gone. `config/set` now collects inside its own write lock, comparing the
+  configuration it replaced with the one it accepted: a file the old revision
+  referenced and the new one does not is removed, and any other unreferenced
+  upload is left alone until it is an hour old, because a fresh one may belong
+  to a transaction that has not committed yet.
+- **The static space card shows its plan background again (R3-2).** It signed
+  the url and then threw the result away — `getCardSize()` mutated a throwaway
+  model while `render()` rebuilt its own from the config — so the `<image>` kept
+  requesting the protected path and got a 401 on every render. Both cards now
+  share one signer, which also gives the static card the batching, the
+  expiry handling and the periodic re-signing the main card already had. Its
+  pending set is released in `finally`, so a single failed request no longer
+  wedges a url for the life of the page.
+- New tests: five backend cases for the two-client interleavings from the report
+  (late commit, uncommitted upload, aged orphan, foreign files, rejected save),
+  the collector extracted to a pure module and unit-tested, and
+  `smoke_space_card_bg` for the signed background — it fails on v1.45.0 with the
+  raw url in the DOM.
+
+## v1.45.0 — 2026-07-27 (external review of v1.44.8: R2-1, R2-2, R2-3)
+- **A rejected save can no longer damage a working plan (R2-1, high).** The
+  plan file was written to its final name — deleting the previous extension on
+  the way — *before* the revision-checked config write. If that write was then
+  rejected (revision conflict, validation, lost connection), the live plan had
+  already been replaced, or the stored config was left pointing at a file that
+  no longer existed. Uploads now go to a versioned name
+  (`<space>.<token>.<ext>`) and nothing is deleted; the card asks the backend to
+  drop the superseded files only after the config write is accepted. A crash in
+  between leaves one orphan, which the next successful upload collects.
+- **Signed urls no longer expire for good on long-lived screens (R2-2).** The
+  backend signs at most 200 paths per request and silently ignores the rest,
+  while the card sent its whole cache in one call and treated any cached entry
+  as valid forever. Past 200 attachments the later ones stopped being refreshed
+  and, 24 hours in, quietly broke. Requests are now batched to the shared limit,
+  entries carry their age (aging urls keep working while a replacement is
+  fetched, expired ones are never served), and the cache is pruned to the urls
+  the current config still references.
+- **Room climate is computed once per update instead of once per room (R2-3).**
+  Each room asked for temperature and humidity separately, and every ask
+  rescanned the entire entity registry: with 60 rooms and 2000 entities that is
+  ~120 traversals per render, enough to spend a whole frame on metadata that had
+  not changed. One pass now builds a map for all areas, keyed on the Home
+  Assistant snapshot, so fresh states are always observed while unrelated
+  re-renders cost nothing. Measured in the smoke: 133 registry scans per update
+  before, 2 after — and no longer growing with the number of rooms.
+- `smoke_ux_fixes` wrote its screenshot to a hard-coded `/tmp` path and could
+  not run on Windows; it uses the OS temp directory now.
+- New tests: `smoke_plan_upload_reject` (cleanup happens only after an accepted
+  save), `smoke_sign_cap` (201 urls, batching, pruning, expiry),
+  `smoke_climate_once` (scan count does not grow with rooms), plus backend
+  coverage for the versioned plan names and unit tests for the new helpers.
+
+## v1.44.8 — 2026-07-27
+- **An uploaded plan is actually attached to the space.** `_saveSpaceDialog`
+  held a reference to the space object across the `await` that uploads the
+  image. Every `houseplan_config_updated` event runs `_reloadConfigOnly()`,
+  which *replaces* `_serverCfg` — so the reference became an orphan and
+  `plan_url`, `aspect`, the title and all display settings were written into a
+  detached object while the save shipped the untouched config. The file landed
+  on disk, the plan never appeared, and re-saving could not help. Creating a
+  space in that window lost the space entirely.
+  The upload now happens *before* the config is touched, and nothing is held
+  across an await.
+- **`_saveConfigNow` marks the write in flight** (`_cfgWriting`), like the
+  debounced writer already did, so a remote revision arriving mid-save defers
+  its reload instead of replacing the config underneath it (audit L2 extended
+  to this path).
+- Regression test `demo/smoke_plan_upload_race.mjs` fails on v1.44.7 and passes
+  here.
+
+## v1.44.7 — 2026-07-27
+- **Plan backgrounds are visible again (regression from v1.44.5).** Since the
+  content endpoint requires authentication, the card asks the backend to sign
+  the plan's url — but the signing happened inside the *memoized* space model,
+  which is cached on the config fingerprint. The unsigned url froze in that
+  cache, so the signature never reached the `<image>` element and the plan never
+  loaded. The url is now resolved at render time, outside the cache. (PDF links
+  were unaffected — they already resolved at render time.)
+- **No more "failed login attempt" from your own IP.** While the plan was
+  broken the browser kept requesting the unsigned path, which returns 401 and
+  makes Home Assistant raise a login-attempt warning for the viewer's own
+  address. The card now renders nothing until the signature is in hand, so an
+  unsigned request is never made.
+- **Long-lived screens no longer blink.** The 12-hour re-signing used to drop
+  every signature and wait for new ones; it now keeps the current urls until the
+  replacements arrive, so a wall tablet never shows an empty plan.
+- Regression test `demo/smoke_plan_signed.mjs` fails on v1.44.6 and passes here.
+
+## v1.44.6 — 2026-07-27
+- **Only room *air* counts as room climate.** After v1.44.5 started reading the
+  area registry instead of the visible icons, every hidden temperature entity in
+  the area became a candidate — including ones that measure something other than
+  the air. Three guards now run before averaging: entities marked
+  diagnostic/config are skipped, entities from curated-out integrations are
+  skipped, and entity ids naming a non-air medium are skipped
+  (`water`, `coolant`, `flow_temp`, `return_temp`, `target`, `setpoint`, `chip`,
+  `cpu`, `processor`, `board`, `device_temp`, `batter`, `freezer`, `fridge`,
+  `oven`, `kettle`, `boiler`).
+  On a live 60-area install this removed four real false positives: a NAS
+  processor temperature, the water in a smart kettle, a 90 °C sauna heater and a
+  virtual `better_thermostat` duplicating the real sensor.
+- **New icon rules:** kettles/thermopots get `mdi:kettle`, saunas
+  (`sauna`, `harvia`, `парная`) get `mdi:hot-tub` — previously both fell through
+  to the generic thermometer rule, which is also what made them count as room
+  climate.
+
+## v1.44.5 — 2026-07-27
+- **Room climate now counts every sensor in the area**, including devices that
+  are not placed on the plan (hidden by curation or by you). Previously the
+  average was taken over the visible icons only, so hiding a thermometer
+  silently removed it from the room card, the tooltip and the temperature fill.
+  Curation still applies (fridges, TRVs and chip-temperature plugs stay out),
+  and an explicit per-room source still wins.
+- The room tooltip no longer says "open the area" — clicking a room stopped
+  navigating in v1.40.1; the link icon on the room card does that.
+
+
+## v1.44.4 — 2026-07-27 (audit follow-up: B2, B5, L4)
+- **One authorization policy (B2).** The HTTP upload view still failed **open**
+  when the config entry was unavailable while the WebSocket path failed closed —
+  the two had drifted apart. Both now call the same `may_write` helper, which
+  denies non-admins whenever the policy cannot be read.
+- **NaN/Infinity refused on every coordinate (B5).** The finite-number check
+  guarded only layout positions; room rects, polygon vertices, `view_box` and
+  opening coordinates accepted `"NaN"`, which serializes to `null` and corrupts
+  the stored geometry permanently. The `MAX_OPENINGS` cap was defined but never
+  wired in — the openings list was unbounded.
+- **Drag hardening (L4 sub-item).** The tolerant `setPointerCapture` wrapper is
+  now used by every drag pipeline (device, label, resize), not just openings —
+  an inactive pointer id could kill a drag outright. Decor shapes gained a
+  bounds clamp: they can no longer be dragged far outside the plan and saved
+  there.
+
+## v1.44.3 — 2026-07-27 (fix: plans and manuals load again)
+- **The authenticated content endpoint had no working browser path.** v1.43.0
+  closed the security hole correctly, but Home Assistant authenticates HTTP
+  requests by a Bearer header or an `authSig` signed path — and an SVG
+  `<image href>` or a plain `<a href>` sends neither. Plan backgrounds and PDF
+  links returned **401** on a real dashboard (reproduced live before the fix).
+  The card now asks the backend to sign what it displays
+  (`houseplan/content/sign`, 24 h, bound to the session's refresh token, only
+  for our own endpoint), re-renders when signatures arrive, and refreshes them
+  every 12 hours so wall tablets keep working. A backend test fetches a signed
+  url **without** an Authorization header and asserts 200, and 401 without the
+  signature.

+
+## v1.44.2 — 2026-07-27 (external code review: CR-1…CR-3)
+
+A second, adversarial review (of v1.44.0) produced three findings; all are
+addressed.
+
+- **The lock invariant is now precise and enforced (CR-1).** The reviewer was
+  right that "locks can never be actuated from the plan" was too absolute a
+  claim: the door card's Unlock button does call the service. That button is a
+  deliberate product decision, so the invariant is restated where it belongs
+  ("never by an accidental tap; exactly one labeled surface"), unlocking now
+  **asks for confirmation**, and a new smoke exercises all five actuation paths
+  to prove icons, `controls[]` and the device card still refuse locks outright.
+- **Attachment migration became transactional (CR-2).** Rebinding a marker used
+  to MOVE its files before the revision-checked config save — if that save was
+  rejected, the stored config kept the old urls while the files had already
+  left. Now the server **copies**, the config is committed, and only then the
+  old folder is removed (`houseplan/files/cleanup`).
+- **Failed or partial migrations no longer rewrite urls (CR-3).** The copy
+  reports an exact `{source: written}` mapping; only confirmed copies are
+  rewritten, name collisions get a unique name instead of silently linking a
+  pre-existing file, and a failed migration surfaces as a toast with the links
+  left pointing at the still-existing originals.
+
+## v1.44.1 — 2026-07-27
+- Added the community chat everywhere users look: **https://t.me/ha_houseplan**
+  (badge and header line in both READMEs, a "Getting help" section, the issue
+  template contact links, CONTRIBUTING, STATUS and SCOPE).
+
+## v1.44.0 — 2026-07-27 (user feedback: control first)
+
+- **The device card is now a control surface.** It opens with the device's
+  controllable entities: lights, switches and fans toggle straight from the
+  card with finger-sized buttons, covers/locks/climate open Home Assistant's
+  own more-info. Model, links and PDF manuals moved below — on a wall tablet
+  this card is for running the home, not for reading documentation (field
+  report). Config and diagnostic entities are not listed; locks still never
+  toggle from a card tap.
+- **"This device is a light source"** — a new per-device flag. A smart switch
+  driving ordinary (dumb) fixtures now casts a glow in the "Light sources"
+  fill without inventing a light-group helper: the glow follows the switch, or
+  the lights bound under "Controls light sources" when they are set.
+
+## v1.43.3 — 2026-07-27 (user feedback: discoverability and touch)
+
+- **Room settings were unfindable.** The gear added in v1.42.0 lived inside the
+  room label at 0.9em of its font and 60% opacity — a few pale pixels on a
+  normal plan. It is now a pill button "⚙ Room" of a fixed, readable size that
+  does not shrink with the card font, and it appears on **unnamed rooms too**
+  (that is where you name them). This also unblocks the font-size sliders,
+  which nobody could reach.
+- **Metrics line enlarged** from 0.62 to 0.75 of the room name — the reporter
+  could scale the name but the sensor line stayed unreadable on a tablet. The
+  per-room and per-space multipliers still apply on top.
+- **Touch tooltips, take two.** The `(hover: none)` guard was not enough: some
+  devices, skins, styluses and paired mice report `hover: hover`, so tips still
+  stuck under the finger. The card now also latches on the first touch/pen
+  pointer event and drops any open tooltip on touch.
+
+## v1.43.2 — 2026-07-27 (external audit: the test layer)
+
+- **The smoke suite can finally fail (T1).** All 48 headless-browser smokes used
+  to print booleans and exit 0 — a regression was visible in their own output
+  and still reported success. `demo/serve.mjs` now exports `check`/`checkAll`/
+  `finish`: every fact is asserted by name, mismatches and uncaught exceptions
+  inside the card set a non-zero exit code. Verified by deliberately breaking
+  the kiosk editor guard: the matching smoke went red.
+- **The suite runs in CI (T2)** as a `smoke` job gated on `frontend`, against a
+  freshly built bundle (the committed `demo/srv/assets` copy is a snapshot and
+  would have tested stale code), uploading per-file logs on failure.
+- **`docs/TESTING.md` reconciled (T3).** `[auto]` now means "a named check
+  exists that fails when this breaks", and each such line names it; 72 lines
+  whose automation was aspirational are honestly marked `[manual]`. Two
+  long-standing contradictions fixed: the "ZERO edit buttons in View" line
+  (wrong since v1.30.1) and the opening-click line (true again since v1.43.1).
+- Three smokes carried expectations that predate v1.39.0/v1.25 and quietly
+  described old behaviour; they now test the current contract.
+
+## v1.43.1 — 2026-07-27 (external audit: P1 fixes)
+
+- **Render cost (L1).** Home Assistant replaces `hass` on every state change in
+  the home, and each of those renders recomputed the whole plan geometry —
+  `_openPairs()` ran once per room (O(rooms³) collinear-overlap math) and the
+  space model was rebuilt twice. Both are now memoized on the config's
+  structural fingerprint and hoisted out of the per-room loop; cache
+  invalidation happens synchronously at mutation time, not inside the debounce.
+- **Opening tap vs drag (L4).** Dragging a door/window had no movement
+  threshold, so any pointer jitter counted as a drag: the properties dialog
+  never opened and an unchanged config was written (which then fed the L2 race).
+  Now the same 3 px threshold as every other drag pipeline, and the write only
+  happens when the geometry actually changed.
+- **Concave rooms (G2).** Containment used the arithmetic mean of the vertices
+  as an "interior point" — which lies OUTSIDE U- and L-shaped rooms, so island
+  rooms in them were rejected as overlaps and their holes never rendered. A
+  real interior point is computed instead (`interiorPoint`).
+- **Wall dedup (G3).** `segKey` ordered endpoints by raw floats but printed
+  rounded ones, so one shared wall could produce two keys and be drawn twice.
+  Rounds first, then orders.
+- **Backend hardening (B2–B5).** The write-authorization check now fails
+  **closed** when the config entry is unavailable (it used to allow writes
+  during a reload); `layout/set` supports `expected_rev` and conflicts like the
+  config store; a `config/set` without `expected_rev` over a non-empty store
+  logs a warning; coordinates reject NaN/Infinity, and spaces/rooms/markers/
+  decor/layout have generous size caps.
+
+## v1.43.0 — 2026-07-27 (external audit: P0 fixes)
+
+An external code audit of v1.41.1 found four critical issues. All four are fixed
+and covered by regression tests.
+
+- **Silent data loss on save (L2).** A debounced config write read the config at
+  fire time, so a `houseplan_config_updated` event arriving in between replaced
+  it and the user's edit vanished with no error — reproducible in a single tab.
+  The debounce now supports `flush()`/`pending()`, a reload flushes the pending
+  write first and defers while a write is in flight, and a failed reload finally
+  reports instead of staying silent.
+- **Split corrupted room geometry (G1).** A cut starting and ending on the SAME
+  wall (carving a niche — a natural action) produced two overlapping,
+  self-intersecting rooms whose areas summed to twice the original, and the
+  overlap guard did not catch it. Same-edge cuts now carve the niche correctly,
+  and a partition invariant (parts must sum to the original) rejects anything
+  else.
+- **Plans and uploaded files were served without authentication (B1).** Anyone
+  who could reach the HA endpoint could fetch floor plans and attached manuals
+  without logging in. They are now served by an authenticated view; stored
+  legacy URLs are rewritten on read, so nothing breaks. **The old public paths
+  disappear after a Home Assistant restart.**
+- **Dialogs could resurrect and blank the card (L3).** Closing a dialog while
+  its save was in flight, on a failed save, spread `null` into a truthy husk;
+  the renderer then threw and the card went blank until reload. Guarded in all
+  four save routines; the error toast still fires.
+
 ## v1.42.2 — 2026-07-26
 - Touch devices no longer pop hover tooltips on every tap (field feedback:

+## v1.46.0 — 2026-07-28 (полный внешний аудит v1.45.4: HP-1454-01 … -10)
+
+**Безопасность**
+
+- **Загруженный SVG-план больше не является живым документом origin вашего
+  Home Assistant (HP-1454-01, high — блокер релиза).** Внутри карточки план
+  подключён через `<image>`, где скрипты не выполняются; но тот же URL,
+  открытый напрямую, становился документом верхнего уровня в origin самого HA,
+  и `<script>` в нём мог читать `localStorage` сессии и обращаться к API. Для
+  загрузки нужно право записи, а оно по умолчанию есть у каждого
+  аутентифицированного пользователя, и подписанную ссылку несложно передать
+  администратору. Ответы с SVG теперь несут заголовок Content-Security-Policy
+  `sandbox`, который помещает документ в opaque origin. Только SVG — CSP на PDF
+  способен сломать встроенный просмотрщик браузера, а растровая картинка ничего
+  выполнить не может. Для существующих планов ничего не меняется: карточка
+  рисует их ровно как раньше.
+
+**Целостность данных**
+
+- **Инструкция, приложенная к устройству, больше не затирает предыдущую
+  (HP-1454-02).** Загрузка писала прямо в `<маркер>/<имя файла>`, вне
+  транзакции конфигурации: отмена диалога или отвергнутое сохранение оставляли
+  сохранённую ссылку указывающей на новые байты. А все новые иконки грузили в
+  одну общую папку, поэтому две с файлом `manual.pdf` начинали ссылаться на
+  один физический файл. Теперь загрузка занимает свободное имя и никогда не
+  перезаписывает, новая иконка получает собственную промежуточную папку, файлы
+  из которой переезжают к настоящей иконке при принятом сохранении, а загрузка,
+  которую никто не сохранил, убирается через час. Имя, на которое уходит
+  коллизия, сменилось с `manual (2).pdf` на `manual-2.pdf`: старое санитайзилось
+  на обратном пути, поэтому переименованное вложение записывалось и больше не
+  отдавалось (нашёл новый тест; до этого релиза так же ломались коллизии при
+  перепривязке).
+- **Две быстрые правки больше не теряют вторую (HP-1454-03).** Debounce
+  разносил старты сохранения, а не сами сохранения. Если одно длилось дольше
+  полусекунды — занятый сервер, медленная связь, — следующая правка уходила с
+  той же ревизией, сервер принимал первую и отклонял вторую, а обработчик
+  конфликта перечитывал серверную копию поверх локальной. Правка исчезала, и
+  сообщение винило «другое окно», которого не было. Записи сериализованы: по
+  одной за раз, каждая с ревизией, которую вернула предыдущая.
+
+**Корректность и пределы**
+
+- **Открытые границы снова следуют за геометрией (HP-1454-04).** Их кэш
+  ключевался только по id комнат и связям, поэтому смена пропорций
+  пространства или перетаскивание вершины оставляли открытые границы — и свет,
+  который через них проходит, — в старых координатах до перезагрузки. Ключом
+  стала сама отрисованная модель, из которой они и вычисляются.
+- **Конфигурацию больше нельзя сделать сколь угодно тяжёлой (HP-1454-05).**
+  Внешние коллекции были ограничены, вложенные — нет. Полигон на 150 000 точек
+  или список из 100 000 идентификаторов проходили валидацию, а потом каждый
+  рендер по ним ходил. Появились пределы на вершины полигона, связи открытых
+  границ, управляемые сущности, вложения, длину текста и ссылок, плюс общий
+  предел размера сериализованной конфигурации. Устаревшее поле `segments`
+  отбрасывает сервер, а не надежда на современный клиент.
+- **Большие файлы передаются потоком, а не через память (HP-1454-06).**
+  Инструкция на 50 МБ целиком читалась в память на приёме и ещё раз на отдаче;
+  пара параллельных скачиваний — заметная нагрузка на слабый хост Home
+  Assistant. Загрузка пишется во временный файл потоком, отдача идёт с диска.
+
+**Согласованность**
+
+- **Статическая карточка пространства учитывает настройки заливки комнаты
+  (HP-1454-07).** Она строит модель другой функцией, и настройки комнаты в неё
+  не переносились — комната, которой вы выключили заливку, всё равно
+  закрашивалась.
+- **Перемещение иконки сразу видно на статической карточке (HP-1454-08).**
+  Layout — отдельное состояние без ревизии и без события: перетаскивание на
+  полной карточке оставляло соседнюю статическую со старой позицией до
+  изменения конфигурации или перезагрузки страницы. Теперь записи layout хранят
+  ревизию, возвращают её и сообщают о себе — заодно оптимистическая блокировка
+  на полной записи layout начала что-то значить, ведь точечная запись раньше
+  сбрасывала счётчик.
+- **Предупреждение о пропавшем плане исчезает вместе с пространством
+  (HP-1454-09).** Уборка смотрела только на существующие пространства, поэтому
+  удаление или переименование оставляло предупреждение в «Ремонте» навсегда.
+- Сборка: `serialize-javascript` поднят выше двух advisory (HP-1454-10). В
+  рантайме недостижим, production-зависимости и так были чисты, но это одна
+  строка.
+
+## v1.45.4 — 2026-07-28 (ревью v1.45.3: R5-1, R5-2)
+- **Частично успешный ответ на подпись больше не пропускает выдержку (R5-1).**
+  Бэкенд подписывает каждый путь независимо: тот, что подписать не удалось,
+  логируется, пропускается, и вызов всё равно завершается успешно с остальными
+  ссылками. Карточка считала любой успешный вызов «весь батч готов», сбрасывала
+  выдержку для всех путей в нём и записывала только вернувшиеся ссылки — и путь,
+  который бэкенд стабильно пропускал, запрашивался заново на каждом рендере, то
+  есть ровно то усиление, ради которого выдержка и вводилась в v1.45.2. Теперь
+  путь считается подписанным, только если в ответе действительно есть ссылка на
+  него; остальные уходят в выдержку по отдельности, ключи, которых не просили,
+  игнорируются, а перерисовка запускается лишь при появлении хотя бы одной новой
+  подписи.
+- **Снимок состояния больше не противоречит репозиторию (R5-2).** Там всё ещё
+  было написано, что в `main` лежат релизы только до v1.40.1, и приводились
+  счётчики тестов на несколько релизов назад — при том что строка версии рядом
+  исправно обновлялась. Читающий его человек или агент получал неверную
+  модель веток и заниженное представление о покрытии. Роли веток описаны точно,
+  а счётчики убраны: `npm run inventory` печатает их из дерева, и устаревать
+  больше нечему.
+
+## v1.45.3 — 2026-07-27
+- **«Значение вместо иконки» невозможно было сохранить (issue #3).** Опция
+  появилась в редакторе устройств ещё в v1.26.0, но серверная схема всё это
+  время принимала только `badge`, `ripple` и `icon_ripple`. При её выборе
+  сохранение падало с
+  `not a valid value for dictionary value @ data['config']['markers'][n]['display']`,
+  а поскольку один отвергнутый маркер валит всю запись конфигурации, план не
+  сохранялся вообще, пока настройку не отменишь. Спасибо @RemyRoux за отчёт и
+  точный текст ошибки.
+- **Списки опций теперь в одном месте и сверяются между языками.**
+  `DISPLAY_MODES`, `TAP_ACTIONS`, `SPACE_FILL_MODES` и `ROOM_FILL_MODES`
+  экспортируются из карточки, и backend-тест читает их, проверяя, что схема
+  принимает каждое значение, которое пользователь реально может выбрать.
+  Теперь добавить опцию в редактор и забыть про схему — значит уронить тесты, а
+  не узнать об этом из чужого сообщения об ошибке.
+
+## v1.45.2 — 2026-07-27 (закалка по ревью v1.45.1: R4-1, R4-2)
+- **Сбой уборки больше не превращает принятое сохранение в ошибку (R4-1).**
+  Сборка вытесненных файлов плана идёт уже после того, как конфигурация
+  сохранена, но ошибка при обходе каталога — он может исчезнуть или стать
+  недоступным между проверкой и обходом — вылетала наружу из `config/set`.
+  Клиент видел неудачу для ревизии, которую сервер закоммитил, а его повтор
+  возвращался с конфликтом. Теперь сборщик сообщает «ничего не убрано» вместо
+  исключения, а `config/set` пишет в лог и продолжает: событие уходит, новая
+  ревизия возвращается.
+- **Один запрос подписи на ссылку вместо одного на рендер (R4-2).** Множество
+  ожидающих очищалось в момент отправки батча, а не по возвращении, поэтому
+  пока запрос `content/sign` был в полёте, каждая перерисовка ставила ещё
+  один — шесть вызовов там, где нужен один, и куда хуже на медленном (а не
+  просто занятом) сокете. Состояния «в очереди» и «в полёте» теперь разделены,
+  после ошибки включается выдержка (2 с с удвоением до 60 с) вместо повтора на
+  следующем кадре, а запрос, который так и не завершился, перестаёт блокировать
+  повторы через 15 с. Поздний ответ, пришедший после размонтирования карточки,
+  больше не вызывает перерисовку.
+- Тесты: восемь юнит-тестов подписывателя с ручным разрешением promise (четыре
+  падают на v1.45.1), backend-тест на то, что сломанный сборщик оставляет
+  сохранение успешным с рабочей ревизией, и проверка исчезнувшего каталога в
+  тестах чистого сборщика.
+
+## v1.45.1 — 2026-07-27 (повторное ревью v1.45.0: R3-1, R3-2)
+- **Уборка старых файлов плана перенесена внутрь транзакции конфига (R3-1,
+  high).** v1.45.0 сделала загрузку безопасной, но отдала удаление клиенту:
+  после успешного сохранения карточка просила бэкенд убрать всё, кроме только
+  что закоммиченного файла. Два открытых редактора невозможно упорядочить —
+  задержавшийся запрос одного клиента удалял план, который только что сохранил
+  другой, и принятая конфигурация оставалась со ссылкой в пустоту, то есть
+  ровно с тем ущербом, ради которого вводился copy-on-write. Команда
+  `houseplan/plan/cleanup` убрана. Теперь `config/set` убирает сам, под своей
+  блокировкой, сравнивая конфигурацию, которую заменил, с той, которую принял:
+  файл, на который ссылалась старая ревизия и не ссылается новая, удаляется, а
+  любая другая непривязанная загрузка не трогается, пока ей не исполнится час —
+  свежая может принадлежать ещё не завершённой чужой транзакции.
+- **Статическая карточка пространства снова показывает подложку (R3-2).** Она
+  подписывала URL и выбрасывала результат — `getCardSize()` правил временную
+  модель, а `render()` строил свою заново из конфига, — поэтому `<image>`
+  запрашивал защищённый путь и на каждом рендере получал 401. Обе карточки
+  теперь используют один подписыватель, и статическая заодно получила батчи,
+  учёт срока годности и периодическое переподписывание, которые были только у
+  основной. Её множество ожидающих запросов освобождается в `finally`, так что
+  одна неудача больше не блокирует ссылку до конца жизни страницы.
+- Новые тесты: пять backend-сценариев чередования двух клиентов из отчёта
+  (поздний коммит, незакоммиченная загрузка, устаревший сирота, чужие файлы,
+  отвергнутое сохранение), сборщик вынесен в чистый модуль и покрыт юнит-
+  тестами, плюс `smoke_space_card_bg` на подписанный фон — он падает на
+  v1.45.0, где в DOM попадает сырой URL.
+
+## v1.45.0 — 2026-07-27 (внешнее ревью v1.44.8: R2-1, R2-2, R2-3)
+- **Отвергнутое сохранение больше не может испортить рабочий план (R2-1,
+  high).** Файл плана записывался под финальным именем — попутно удаляя вариант
+  с другим расширением — *до* проверки ревизии конфига. Если запись потом
+  отвергалась (конфликт ревизий, валидация, обрыв связи), живой план оказывался
+  уже подменён, а сохранённый конфиг мог ссылаться на удалённый файл. Теперь
+  загрузка идёт в версионированное имя (`<space>.<токен>.<ext>`) и ничего не
+  удаляется; карточка просит бэкенд убрать устаревшие файлы только после
+  принятой записи конфига. Падение между шагами оставляет один осиротевший
+  файл, который подберёт следующая успешная загрузка.
+- **Подписанные ссылки больше не протухают навсегда на долгоживущих экранах
+  (R2-2).** Бэкенд подписывает не более 200 путей за запрос и молча отбрасывает
+  остальные, а карточка отправляла весь кэш одним вызовом и считала любую
+  запись годной вечно. Начиная с 201-го вложения поздние ссылки переставали
+  обновляться и через 24 часа тихо ломались. Теперь запросы бьются на батчи по
+  общему лимиту, записи помнят свой возраст (стареющая ссылка работает, пока
+  едет замена, протухшая не отдаётся вовсе), а кэш чистится до ссылок, на
+  которые конфиг всё ещё ссылается.
+- **Климат комнат считается один раз на обновление, а не на каждую комнату
+  (R2-3).** Каждая комната запрашивала температуру и влажность по отдельности,
+  и каждый запрос заново обходил весь реестр сущностей: 60 комнат и 2000
+  сущностей — это ~120 обходов на рендер, целый кадр на метаданные, которые не
+  менялись. Теперь один проход строит карту по всем зонам с привязкой к снимку
+  Home Assistant: свежие состояния видны всегда, а посторонние перерисовки не
+  стоят ничего. Замер в смоуке: 133 обхода реестра на обновление до, 2 после —
+  и число больше не растёт с числом комнат.
+- `smoke_ux_fixes` писал скриншот по жёстко зашитому пути `/tmp` и не запускался
+  на Windows — теперь берёт временную папку у ОС.
+- Новые тесты: `smoke_plan_upload_reject` (чистка только после принятого
+  сохранения), `smoke_sign_cap` (201 ссылка, батчи, чистка, срок годности),
+  `smoke_climate_once` (число обходов не растёт с числом комнат), плюс
+  backend-покрытие версионированных имён и юнит-тесты новых хелперов.
+
+## v1.44.8 — 2026-07-27
+- **Загруженная подложка действительно привязывается к пространству.**
+  `_saveSpaceDialog` держал ссылку на объект пространства через `await`
+  загрузки картинки. Любое событие `houseplan_config_updated` запускает
+  `_reloadConfigOnly()`, а оно *заменяет* `_serverCfg` — ссылка становилась
+  осиротевшей, и `plan_url`, `aspect`, заголовок и все настройки отображения
+  писались в отсоединённый объект, тогда как на сервер уходил нетронутый
+  конфиг. Файл попадал на диск, подложка не появлялась, пересохранение не
+  помогало. Создание пространства в этот момент теряло пространство целиком.
+  Теперь загрузка идёт *до* обращения к конфигу, и ни одна ссылка не живёт
+  через await.
+- **`_saveConfigNow` помечает запись как выполняющуюся** (`_cfgWriting`) — так
+  же, как отложенный писатель, — поэтому чужая ревизия, пришедшая посреди
+  сохранения, откладывает перечитывание вместо подмены конфига (аудит L2,
+  расширен на этот путь).
+- Регрессионный тест `demo/smoke_plan_upload_race.mjs` падает на v1.44.7 и
+  проходит здесь.
+
+## v1.44.7 — 2026-07-27
+- **Подложки снова отображаются (регрессия с v1.44.5).** Эндпоинт с файлами
+  требует авторизации, поэтому карточка просит бэкенд подписать ссылку на план —
+  но подпись подставлялась внутри *мемоизированной* модели пространства, а она
+  кэшируется по отпечатку конфига. Неподписанная ссылка «замерзала» в кэше,
+  подпись до элемента `<image>` не доезжала, и план не грузился никогда. Теперь
+  ссылка вычисляется в момент отрисовки, вне кэша. (Ссылки на PDF не страдали —
+  там она и так вычислялась при отрисовке.)
+- **Больше нет «неудачной попытки входа» с собственного IP.** Пока подложка была
+  сломана, браузер продолжал дёргать неподписанный путь, тот отвечал 401, и
+  Home Assistant поднимал предупреждение о неудачном входе с адреса самого
+  зрителя. Теперь до получения подписи не рисуется ничего, и неподписанный
+  запрос не уходит вовсе.
+- **Долгоживущие экраны не моргают.** Переподписывание раз в 12 часов раньше
+  сбрасывало все подписи и ждало новые; теперь текущие ссылки держатся до
+  прихода замены, так что настенный планшет не показывает пустой план.
+- Регрессионный тест `demo/smoke_plan_signed.mjs` падает на v1.44.6 и проходит
+  здесь.
+
+## v1.44.6 — 2026-07-27
+- **Климатом комнаты считается только температура *воздуха*.** После v1.44.5,
+  когда данные стали браться из реестра зон, а не с видимых значков,
+  кандидатами стали все скрытые датчики температуры в зоне — в том числе те,
+  что меряют вовсе не воздух. Перед усреднением теперь работают три фильтра:
+  пропускаются сущности с категорией диагностика/настройка, сущности
+  исключённых интеграций и сущности, в id которых назван не-воздушный носитель
+  (`water`, `coolant`, `flow_temp`, `return_temp`, `target`, `setpoint`, `chip`,
+  `cpu`, `processor`, `board`, `device_temp`, `batter`, `freezer`, `fridge`,
+  `oven`, `kettle`, `boiler`).
+  На живой установке с 60 зонами это убрало четыре реальных ложных
+  срабатывания: температуру процессора NAS, воду в умном чайнике, сауну с 90 °C
+  и виртуальный `better_thermostat`, дублирующий настоящий датчик.
+- **Новые правила иконок:** чайники и термопоты получают `mdi:kettle`, сауны
+  (`sauna`, `harvia`, `парная`) — `mdi:hot-tub`. Раньше и те и другие попадали
+  под общее правило термометра, из-за чего и учитывались в климате комнаты.
+
+## v1.44.5 — 2026-07-27
+- **Климат комнаты считается по всем датчикам зоны**, включая устройства,
+  которых нет на плане (скрыты курированием или вами). Раньше среднее бралось
+  только по видимым значкам, поэтому скрытый термометр молча выпадал из
+  карточки комнаты, подсказки и температурной заливки. Курирование сохранено
+  (холодильники, термоголовки и розетки с температурой чипа не считаются), а
+  явно выбранный источник в настройках комнаты по-прежнему главнее.
+- Из подсказки к комнате убрана фраза «открыть зону» — клик по комнате перестал
+  никуда вести ещё в v1.40.1, для перехода есть значок-ссылка у названия.
+
+
+## v1.44.4 — 2026-07-27 (доработка по аудиту: B2, B5, L4)
+- **Единая политика авторизации (B2).** HTTP-загрузка по-прежнему **разрешала**
+  запись, когда запись о конфигурации недоступна, тогда как WebSocket-путь уже
+  отказывал — они разошлись. Теперь оба вызывают общий помощник `may_write`,
+  который в неопределённой ситуации пропускает только администраторов.
+- **NaN/Infinity отвергаются во всех координатах (B5).** Проверка на конечность
+  числа стояла только у позиций раскладки; прямоугольники комнат, вершины
+  полигонов, `view_box` и координаты проёмов принимали `"NaN"`, который при
+  записи превращается в `null` и необратимо портит геометрию. Ограничение
+  `MAX_OPENINGS` было объявлено, но нигде не использовалось — список проёмов
+  оставался безразмерным.
+- **Укрепление перетаскивания (часть L4).** Безопасная обёртка над
+  `setPointerCapture` теперь используется во всех сценариях перетаскивания
+  (устройства, подписи, изменение размера), а не только у проёмов — «мёртвый»
+  идентификатор указателя мог оборвать перетаскивание. Фигуры декора получили
+  ограничение по границам: их больше нельзя утащить далеко за пределы плана и
+  сохранить там.
+
+## v1.44.3 — 2026-07-27 (исправление: планы и инструкции снова загружаются)
+- **У аутентифицированной выдачи контента не было рабочего пути для браузера.**
+  Версия v1.43.0 закрыла дыру правильно, но Home Assistant аутентифицирует
+  HTTP-запросы либо заголовком Bearer, либо подписанным путём `authSig` — а
+  `<image href>` внутри SVG и обычная ссылка `<a href>` не отправляют ни того,
+  ни другого. На настоящем дашборде фоны планов и ссылки на PDF отдавали
+  **401** (воспроизведено вживую до исправления). Теперь карточка просит бэкенд
+  подписать то, что собирается показать (`houseplan/content/sign`, 24 часа,
+  привязано к токену сессии, только для нашего эндпоинта), перерисовывается,
+  когда подписи приходят, и обновляет их каждые 12 часов, чтобы настенные
+  планшеты продолжали работать. Тест бэкенда скачивает подписанный адрес **без**
+  заголовка авторизации и проверяет 200, а без подписи — 401.
+
+## v1.44.2 — 2026-07-27 (внешнее код-ревью: CR-1…CR-3)
+
+Второе, состязательное ревью (версии v1.44.0) дало три находки — все закрыты.
+
+- **Правило про замки теперь сформулировано точно и проверяется (CR-1).**
+  Рецензент справедливо отметил, что утверждение «замок нельзя открыть с плана»
+  было слишком абсолютным: кнопка в карточке двери действительно вызывает
+  сервис. Эта кнопка — осознанное продуктовое решение, поэтому правило
+  переписано там, где ему место («никогда случайным нажатием; ровно одна
+  подписанная поверхность»), отпирание теперь **спрашивает подтверждение**, а
+  новый смок-тест проверяет все пять путей управления и доказывает, что значки,
+  `controls[]` и карточка устройства по-прежнему отказывают замкам.
+- **Перенос вложений стал транзакционным (CR-2).** При смене привязки маркера
+  файлы раньше ПЕРЕМЕЩАЛИСЬ до сохранения конфига с проверкой ревизии: если
+  сохранение отклонялось, на сервере оставались старые ссылки, а файлы уже
+  уехали. Теперь сервер копирует, конфиг фиксируется, и только после этого
+  старая папка удаляется (`houseplan/files/cleanup`).
+- **Неудачный или частичный перенос больше не переписывает ссылки (CR-3).**
+  Копирование возвращает точное соответствие «исходное имя → записанное»;
+  переписываются только подтверждённые копии, при совпадении имён файл получает
+  уникальное имя вместо молчаливой ссылки на чужой файл, а ошибка переноса
+  показывается тостом.
+
+## v1.44.1 — 2026-07-27
+
+- Ссылка на чат сообщества добавлена везде, где её ищут:
+  **https://t.me/ha_houseplan** (бейдж и строка в шапке обоих README, раздел
+  «Помощь и обмен опытом», контакт-ссылки в шаблонах issue, CONTRIBUTING,
+  STATUS и SCOPE).
+
+## v1.44.0 — 2026-07-27 (отзыв пользователя: сначала управление)
+
+- **Карточка устройства стала поверхностью управления.** Она открывается со
+  списка управляемых сущностей: лампы, розетки и вентиляторы переключаются
+  прямо здесь кнопками под палец, шторы, замки и климат передают управление в
+  штатный more-info Home Assistant. Модель, ссылки и PDF-инструкции ушли ниже —
+  на настенном планшете эта карточка нужна для управления домом, а не для
+  чтения документации (из полевого отзыва). Служебные (config/diagnostic)
+  сущности в списке не показываются, замки по-прежнему не переключаются
+  нажатием в карточке.
+- **«Это устройство — источник света»** — новый флаг у устройства. Умный
+  выключатель с обычными (не умными) светильниками теперь даёт ореол в заливке
+  «Свет по источникам» без создания хелпера-группы: свечение следует за самим
+  выключателем либо за лампами, привязанными в «Управляет источниками света».
+
+## v1.43.3 — 2026-07-27 (отзыв пользователя: обнаруживаемость и тач)
+
+- **Настройки комнаты невозможно было найти.** Шестерёнка из v1.42.0 жила
+  внутри подписи комнаты размером 0.9em от её шрифта и с прозрачностью 60% —
+  несколько бледных пикселей на обычном плане. Теперь это кнопка-пилюля
+  «⚙ Комната» фиксированного читаемого размера, не зависящая от масштаба
+  карточки, и она появляется **даже у комнат без имени** (их там и называют).
+  Заодно разблокировались слайдеры размеров шрифта, до которых никто не мог
+  добраться.
+- **Строка показателей увеличена** с 0.62 до 0.75 от размера названия — автор
+  отзыва мог увеличить название, но строка датчиков оставалась нечитаемой на
+  планшете. Множители комнаты и пространства работают поверх.
+- **Тултипы на тач-устройствах, вторая попытка.** Проверки `(hover: none)`
+  оказалось мало: некоторые устройства, оболочки, стилусы и подключённые мыши
+  сообщают `hover: hover`, и подсказки продолжали висеть под пальцем. Теперь
+  карточка запоминает первое же касание (touch/pen) и гасит открытую подсказку.
+
+## v1.43.2 — 2026-07-27 (внешний аудит: слой тестов)
+
+- **Смок-тесты наконец умеют падать (T1).** Все 48 браузерных смоков печатали
+  булевы значения и всегда завершались с кодом 0 — регрессия была видна в их
+  собственном выводе, а прогон считался успешным. `demo/serve.mjs` теперь
+  экспортирует `check`/`checkAll`/`finish`: каждый факт проверяется по имени,
+  несовпадения и необработанные исключения внутри карточки дают ненулевой код
+  возврата. Проверено намеренной поломкой блокировки редакторов в киоске —
+  соответствующий смок покраснел.
+- **Набор гоняется в CI (T2)** отдельной джобой `smoke` после `frontend`,
+  против свежесобранного бандла (закоммиченная копия в `demo/srv/assets` —
+  снимок, на нём легко получить «зелёный» отчёт о несуществующем коде), с
+  выгрузкой логов при падении.
+- **`docs/TESTING.md` приведён в соответствие (T3).** `[auto]` теперь означает
+  «существует именованная проверка, которая падает», и рядом написано, где она;
+  72 пункта, где автоматизация была намерением, честно помечены `[manual]`.
+  Исправлены два давних противоречия: строка про «ноль кнопок редактирования в
+  Просмотре» (неверна с v1.30.1) и строка про клик по проёму (снова верна
+  с v1.43.1).
+- Три смока проверяли поведение, которого уже нет (ожидания времён v1.39.0 и
+  v1.25); теперь они тестируют текущий контракт.
+
+## v1.43.1 — 2026-07-27 (внешний аудит: исправления P1)
+
+- **Стоимость отрисовки (L1).** Home Assistant подменяет объект `hass` при
+  любом изменении состояния в доме, и каждая такая отрисовка пересчитывала всю
+  геометрию плана — `_openPairs()` вызывался по разу на комнату (кубическая
+  математика коллинеарных наложений), модель пространства строилась дважды.
+  Теперь и то, и другое мемоизируется по структурному отпечатку конфига и
+  вынесено из цикла по комнатам; сброс кэша происходит синхронно в момент
+  мутации, а не внутри дебаунса.
+- **Тап против перетаскивания у проёмов (L4).** У перетаскивания двери или окна
+  не было порога движения, поэтому любое дрожание пальца считалось
+  перетаскиванием: диалог свойств не открывался, а в конфиг писалось
+  неизменённое состояние (что подпитывало гонку L2). Теперь порог 3 px, как во
+  всех остальных сценариях перетаскивания, и запись только при реальном
+  изменении геометрии.
+- **Вогнутые комнаты (G2).** Вложенность определялась через среднее арифметическое
+  вершин — а оно лежит СНАРУЖИ U- и L-образных комнат, поэтому комнаты-острова
+  в них отвергались как пересечение, а дырка в заливке не рисовалась. Теперь
+  вычисляется настоящая внутренняя точка (`interiorPoint`).
+- **Дедупликация стен (G3).** `segKey` сортировал концы по сырым float, а

+
+## v1.43.0 — 2026-07-27 (внешний аудит: исправления P0)
+
+Внешний аудит кода версии v1.41.1 нашёл четыре критические проблемы. Все четыре
+исправлены и покрыты регрессионными тестами.
+
+- **Молчаливая потеря правок при сохранении (L2).** Отложенная запись конфига
+  читала его в момент срабатывания, поэтому пришедшее в промежутке событие
+  `houseplan_config_updated` подменяло конфиг, и правка пользователя исчезала
+  без единой ошибки — воспроизводилось даже в одной вкладке. Теперь дебаунс
+  умеет `flush()`/`pending()`, перезагрузка сперва дописывает отложенную
+  запись и откладывается, пока запись в полёте, а неудачная перезагрузка
+  наконец сообщает о себе вместо молчания.
+- **Разрез разрушал геометрию комнаты (G1).** Разрез, начинающийся и
+  заканчивающийся на ОДНОЙ стене (вырезание ниши — совершенно естественное
+  действие), давал две самопересекающиеся комнаты, суммарная площадь которых
+  вдвое превышала исходную, и проверка пересечений это не ловила. Теперь такие
+  разрезы корректно вырезают нишу, а инвариант разбиения (части в сумме дают
+  исходную площадь) отклоняет всё остальное.
+- **Планы и загруженные файлы отдавались без авторизации (B1).** Любой, кто мог
+  достучаться до вашего Home Assistant, скачивал планы этажей и вложенные
+  инструкции без входа в систему. Теперь их отдаёт аутентифицированный
+  обработчик; сохранённые старые адреса переписываются на чтении, так что
+  ничего не ломается. **Старые публичные пути исчезают только после
+  перезапуска Home Assistant.**
+- **Диалоги могли воскреснуть и обнулить карточку (L3).** Закрытие диалога во
+  время неудачного сохранения превращало его состояние в пустую «оболочку»,
+  отрисовщик падал, и карточка оставалась пустой до перезагрузки страницы.
+  Защита добавлена во все четыре процедуры сохранения, тост об ошибке
+  по-прежнему показывается.
+
+## v1.42.2 — 2026-07-26
+
+- На тач-устройствах подсказки при наведении больше не выскакивают при каждом
+  касании (из отзыва: «на планшете при тапе вылезают доп. надписи — мешают»).
+  Подсказки теперь только для мыши; на тач та же информация есть в карточках
+  комнат и в карточке устройства по долгому нажатию.
+
+## v1.42.1 — 2026-07-26 (размеры шрифтов карточек комнат)
+
+- Закрываем отзыв «нельзя настроить размер шрифта»: **три слайдера**. В
+  настройках пространства появился базовый размер шрифта карточек комнат для
+  всего пространства; в настройках комнаты — независимые размеры **названия** и
+  **строки показателей** (50–300% каждый). Эффекты перемножаются и складываются
+  с растягиванием карточки за уголки и множителем экрана в киоск-режиме.
+- В обоих диалогах показывается **живой пример карточки**, который меняется
+  прямо во время перетаскивания слайдеров.
+
+## v1.42.0 — 2026-07-26 (настройки комнаты — третий уровень)
+
+- **У настроек теперь четыре уровня**: общие → пространство → комната →
+  устройство; более конкретный уровень переопределяет более общий (решение
+  владельца, зафиксировано в ARCHITECTURE). В этом релизе добавлен уровень
+  КОМНАТЫ.
+- У каждой карточки комнаты в редакторе плана появилась **шестерёнка**:
+  переименовать комнату, сменить её зону HA, переопределить **тип заливки**
+  только для этой комнаты (работает и в glow-пространствах — «без заливки»
+  выводит комнату из темноты) и выбрать явный **источник температуры и
+  влажности** — любое устройство или сущность HA вместо среднего по комнате.
+  Источник питает карточку комнаты, всплывающую подсказку и температурную
+  заливку и работает даже у комнат без зоны HA (случай из отзыва: собственный
+  template-сенсор, привязанный к помещению).
+- Тот же раздел настроек появляется в диалоге комнаты сразу после замыкания
+  контура.

+- [ ] Smoke harness itself (v1.43.2, audit T1/T2): every smoke asserts named
+      facts via `check`/`checkAll` and exits non-zero on any mismatch or
+      uncaught in-card exception; the suite runs in CI against a FRESHLY built
+      bundle. Sanity ritual: break one invariant on purpose (e.g. remove the
+      kiosk editor guard) and confirm the matching smoke goes red [auto: CI job "smoke"]
+
+- [ ] Room gear discoverability (v1.43.3, user feedback): in the Plan editor
+      every room card carries a pill button "⚙ Room" of a FIXED readable size
+      (independent of the card font) — including rooms without a name; it opens
+      Room settings [auto: smoke_feedback_v2]
+- [ ] Metrics readability (v1.43.3): the metrics line is 0.75 of the room name
+      (was 0.62 — unreadable on tablets); per-room sliders still apply on top [auto: smoke_feedback_v2]
+- [ ] Touch tooltips, take two (v1.43.3): a hover tooltip never appears after
+      ANY touch/pen pointer event, even if the browser claims `hover: hover`
+      (stylus, paired mouse, vendor skins) [auto: smoke_feedback_v2]
+
+- [ ] Light-source flag (v1.44.0, user feedback): a smart SWITCH driving dumb
+      fixtures glows in the "Light sources" fill once "This device is a light
+      source" is ticked (its own entity or the lights bound under "Controls");
+      unticked devices without a light entity never glow [auto: smoke_glow]
+- [ ] Device card controls (v1.44.0): the device card opens with its
+      controllable entities FIRST — toggles right there (≥30 px tap targets),
+      cover/lock/climate open HA more-info; model, links and manuals moved
+      below; config/diagnostic entities are not listed; locks never toggle from
+      the card [auto: smoke_card_controls]
+
+- [ ] Lock invariant, all paths (v1.44.2, review CR-1): icon tap, controls[],
+      device card and _cardToggle refuse locks/alarm panels entirely; the door
+      card's Unlock asks for confirmation, Lock does not [auto: smoke_lock_invariant]
+- [ ] Attachment migration is transactional (v1.44.2, review CR-2/CR-3):
+      rebinding COPIES files, saves the config, and only then deletes the old
+      folder; a rejected save leaves the old files and urls intact; a name
+      collision in the destination gets a unique name (the pre-existing file is
+      never silently linked); urls are rewritten only for confirmed copies
+      [auto: unit logic.test + tests_backend]
+
+- [ ] Plans and PDFs load in a real browser (v1.44.3, B1 regression): open a
+      dashboard with an uploaded plan — the background renders and a manual link
+      opens; DevTools shows /api/houseplan/content/... returning 200 via a
+      signed url, while the same url without authSig returns 401
+      [auto: tests_backend + manual]
+- [ ] Auth policy is single-sourced (v1.44.4, B2): the HTTP upload and every WS
+      write use the same `may_write`, which denies non-admins when the config
+      entry is unavailable [auto: tests_backend]
+- [ ] Coordinates and caps (v1.44.4, B5): NaN/Infinity are refused on room
+      rects, polygon vertices, view_box and openings — not only in layout; the
+      openings list honours MAX_OPENINGS [auto: tests_backend]
+- [ ] Drag hardening (v1.44.4, L4 sub-item): every drag pipeline captures the
+      pointer through the tolerant helper; decor shapes cannot be dragged more
+      than a quarter of the plan outside the viewBox [auto: smoke_decor]
+
+- [ ] Room climate counts hidden sensors (v1.44.5): a thermometer that is NOT
+      placed on the plan (hidden by curation or by the user) still feeds the
+      room card, the tooltip and the temperature fill; fridges/TRVs still do
+      not; an explicit per-room source still wins [auto: unit devices.test]
+- [ ] Room tooltip wording (v1.44.5): hovering a room shows its name (plus
+      temperature/signal when available) and no longer claims "open the area" —
+      room clicks were removed in v1.40.1 [manual]
