Field report from the dacha: the wall switch "Гостиная основной свет",
whose controls name three virtual light sources, periodically ignored taps
— no toggle, no glow — until its settings dialog was opened once with no
changes. "Periodically" was every fresh tab: the #337 lazy split left
_toggleIntent (and the confirm-line helpers) on the card as stubs
delegating into the editor runtime, so a plain View tap on a cold tab
threw `Houseplan editor runtime is not loaded` synchronously inside the
click handler. Opening any editor surface loaded the runtime and "healed"
the tab for its lifetime.
The View card now owns toggle resolution: _toggleIntent calls
resolveToggleIntent directly (device-toggle.ts was already in the initial
graph; the card owns _planHass/_fullRegistryHass/_virtualLights), and
_toggleStateText/_toggleConfirmationStateText/_toggleConfirmationLines
moved with it. The editor runtime delegates back to the host — one source
of truth, editor consumers (dialog preview, hint lines) unchanged.
Every product smoke preloads the runtime, so none of them could see this
class of regression. The new smoke_cold_view_toggle mirrors the field
config on a genuinely cold tab: a real switch drives three passive
virtual lamps with one tap, a controlled lamp drives its switch back,
tap_confirm renders its state lines and confirms, and the editor chunk is
never requested. A registry mutant restores the old delegation and is
killed by that smoke.
Issue: #357
User-Visible: yes
A fully fictional house (plans, devices, states) used for README screenshots,
the demo GIF and headless smoke tests — so no real home data ever appears in
public materials.
srv/demo.html — self-contained host page: <ha-icon>/<ha-card> stubs and a
fake hass (registries, states, callWS, callService, floors).
srv/assets/ — generated plan SVGs and icons.js (node demo/gen_icons.mjs,
needs the repo's devDependencies). The card bundle is copied from dist/:
npm run bundle:sync (копия стенда не коммитится, #255).
serve.mjs — playwright launcher (route interception, no web server).
smoke_*.mjs — feature smoke tests; run with a Chromium installed via
PLAYWRIGHT_BROWSERS_PATH=<dir> npx playwright install chromium-headless-shell.
Note for sandboxed sessions: /tmp does not survive; this directory is the
persistent home of the harness (docs/DEVELOPMENT.md has the LD_LIBRARY_PATH recipe).
