CODE-REVIEW-397-r1 Medium: AC3 named the second reader of the same
value — _loadFromServer via _adoptStructuralResponses — and nothing
exercised it. Adding the scenario turned out to be less mechanical than
it looked, and both obstacles are worth recording:
The reconnect path reads BOTH answers, and a differing config clears the
history for its own reason (configChanged). The fake server now echoes
the config the card already holds, so the check answers the layout
question it claims to answer.
The first version of the probe used a round 0.42, which canonicalization
leaves untouched — the check passed with and without the fix, i.e. for
the wrong reason. The probe now starts from a non-canonical position
(0.024999999999999942, which snaps to 0.025), and the scenario runs
immediately after the write, before any reload can align the two sides.
Verified by removing the fix: five checks red, now including
reconnectKeepsHistory and deleteEchoKeepsHistory. Both were green in the
weaker version — which is exactly what the reviewer's Medium was about.
User-Visible: no
Issue: #397
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).
