The beta.9 candidate failed the same phase twice in CI with "Resulting
promise was garbage collected" (runs 34346813552, 34347910231) while it
passes locally; a timer guard did not help, which points at a destroyed
context rather than a starved animation-frame chain. The wait now runs as
page.waitForFunction with raf polling, and the smoke logs frame navigations
and page crashes as `diagnostic …` lines so the next failure names its
cause. Verdict unchanged (animationName of the boot house, or 'missed').
Pre-release gate repair per PROCESS §11.4; locally OK ×2.

Validate 34346813552 on the beta.9 candidate failed only in browser smoke
shard 1: smoke_preloader phase 3 died with "Resulting promise was garbage
collected" — its rAF-only wait for the boot house had no other reference
while the runner withheld animation frames. A timer now bounds the wait
and keeps the promise reachable; the verdict is unchanged (animationName
of the house, or 'missed'). Pre-release gate repair per PROCESS §11.4:
locally `node demo/smoke_preloader.mjs` → OK ×2; all other heavy gates of
that run (golden, perf-smoke, backend, shards 2–3) were green.

Owner's report: «план перезагружается при возврате на вкладку, хотя страница
жива». Diagnosis confirmed: Lovelace re-creates the card element when the
websocket reconnects after a long-backgrounded tab, and the fresh instance ran
the FULL first-open boot — veil + BOOT_MIN_MS + quiescence — reading as a plan
reload. On top of that, _loadFromServer's catch nulled _serverCfg after 8
failed tries, so a slow reconnect could genuinely blank an already-shown plan.
DEV-B703-01 warm re-mount: module-scoped memo (lives with the PAGE, not the
instance) of the settled header height, keyed by viewport size × card config.
A repeat instance adopts the settled geometry in setConfig and skips the veil
entirely — synchronous reveal at the saved zoom (HP-1551); a window resize
between instances changes the key and brings the full protective boot back.
The memo follows the live geometry (updated()'s measure) and is written on
every _bootSettled. Test hook: static _warmBootReset().
DEV-B703-02 stale-while-revalidate: an instance that already renders a valid
config (LS snapshot or a successful load) NEVER clears it on WS failures —
the local-only fallback is reserved for a card that never had a backend. A
self-driven retry (backoff, cap 8 s) keeps revalidating after willUpdate's
8-try budget is spent, and a connection 'ready' hook resets the budget and
quietly re-reads the config the moment the socket is back (the event
subscriptions re-subscribe on their own inside home-assistant-js-websocket).
Smokes: smoke_warm_remount (fails pre-fix: veil + hidden plan on re-mount;
resize invalidation stays cold), smoke_ws_resilience (fails pre-fix:
_serverCfg cleared after 8 tries, no revalidation after recovery); the
preloader smokes now reset the warm memo — they simulate a COLD first open.
In normal (non-kiosk) mode the stage is calc(100dvh - _hdrH), and _hdrH is
measured from HA's chrome, which finishes loading AFTER the card's first
paint — late panels nudged the height and the freshly painted plan visibly
jumped (kiosk is a flat 100dvh, hence 'perfect in kiosk').
Fix, per the owner's sketch:
- until the stage height reads the same twice in a row (200 ms cadence) or
a hard ~600 ms cap, the plan stays hidden (.hpboot) and is revealed only
after a refit — not a single frame paints at a stale height;
- that window is covered by a quiet product-style preloader: dark veil,
small pulsing outline house (the card's own mdi:home-city outline,
inline SVG), no text, 0.15 s opacity fade-out;
- prefers-reduced-motion gets a static house; kiosk never shows the veil;
first open of the card instance only — floor/mode switches are untouched.
smoke_preloader simulates an HA panel landing at t=300 ms and asserts the
veil, zero plan-visible frames at a non-final height, the kiosk opt-out and
the reduced-motion variant; serve.mjs starts every smoke after the reveal,
where the user starts.
