Systematic audit after #357 ("can there be more bugs with this root
cause?"): _vacMapId was the one remaining hard stub reachable from the
eager View path. It runs inside willUpdate for every vacuum whose
integration reports live telemetry (Tasshack, XCME, Valetudo), so on a
cold tab the #337 stub threw there and the exception took the whole Lit
update cycle with it — the card froze on its very first frame. The demo
mower has no position attributes, telemetry resolved to null, and every
existing smoke (warm and cold) sailed past the branch.
The card now owns the implementation (both dependencies — _vacEntity and
vacMapIdWithFallback — were already eager); the editor runtime delegates
back to the host. The HP-1541-01 invariant (selected_map: 0 is a real map
id, nullish not truthy) moves verbatim and is pinned by the new smoke.
Hardened alongside (audit Lows): _decorShapeDown gets the same
cold-tab guard its twin _decorShapeDbl received in #337 — decor shapes
render in View and CSS pointer-events alone must not be what prevents a
throw; the _vacCalConfirm dialog renders behind the same _editorRuntime
gate as every other editor dialog instead of relying on the implicit
"only the runtime ever sets it".
smoke_cold_view_vacuum: cold tab, vacuum with vacuum_position and
selected_map: 0 — the card commits three successive telemetry frames
(willUpdate alive, not merely the first paint), map id resolves to '0',
no editor chunk requested, a decor pointerdown is a quiet no-op. A
registry mutant restores the delegation and is killed by that smoke.

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.

The r1 reviewer cut the listener loop in the production registry and all
three #354 units stayed green — the subscription unit was the same class of
decoy the issue itself fights. The fan-out now lives in an exported
notifyLanguageLoadFailures(code); the unit drives it directly and asserts
real delivery, partial unsubscription and silence after the last listener
leaves; the contract unit additionally pins the runtime wiring
(`loadFailed` → notifyLanguageLoadFailures) in source. A new registry
mutant `locale-failure-delivery-cut` replays the reviewer's exact cut and
is killed by the unit. The r1 Low is taken too: both USER-GUIDEs now
mention the toast in the German-failure paragraph.

The production LANGUAGE_RUNTIME was a handwritten twin of the tested
LanguageRuntime class (germanDictionary/Pending/Failed): equivalent on the
day it was written, invisible to every i18n-runtime test afterwards. The
registry now exports one page-scoped `new LanguageRuntime(LANGUAGE_REGISTRY,
…)` instance — the whole existing suite starts proving the object production
actually runs, and a contract unit (instanceof + source free of the old
field names) keeps the duplicate from returning.
The class gains an optional `loadFailed(code)` hook — fired once when a
dictionary load settles into English fallback — and the registry fans it out
through `subscribeLanguageLoadFailures`. Only the View card subscribes (it
alone owns toast infrastructure): a failed language pack now shows the new
`toast.locale_load_failed` message (en/ru/de) instead of a console-only
warning; space card and both GUI editors keep the console warning as before.
Proofs: contract unit, hook unit, subscription unit; smoke_german_locale
extended — the both-attempts-failed scenario now asserts the visible toast;
two new registry mutants (handwritten-twin returns, toast dropped).

Network failure of the editor runtime is no longer terminal: the loader
re-arms to idle and the next explicit press starts a fresh cycle, while a
fingerprint mismatch on either attempt stays terminal. The toast now says
what actually helps — retry advice for the network, refresh advice for a
foreign build — via one shared lazyLoadFailureMessage helper (new i18n key
editor.retry_advice in en/ru/de).
The field smoke caught a second, deeper bug on the way: Chromium records a
FAILED module in the page module map permanently, so retrying the same URL
(even the cache-busted one) never touched the network again. Every retry
now carries a per-cycle nonce and becomes a genuinely new module request.
A proxy-cached stale entry no longer kills the card silently: the entry
facade is rewritten at build time from a static re-export into a top-level
`try{await import(...)}catch{...}` — importers keep the happy-path
guarantee (await import(entry) still resolves only after
customElements.define), and the catch defines a fallback element with a
localized "reload the page" panel. Content-hashed chunks are served with
`public, max-age=31536000, immutable`, and verifyBundleTree now fails on
orphan chunks that the manifest does not name.
Proofs: loader units for re-arm/terminality/toast wording + an AST check
that both loaders forward the terminality flag; smoke_entry_stale (en/ru)
against a tree without the main chunk; smoke_lazy_editor_chunk extended —
second press after network failure now really opens the editor; pytest for
the immutable header; orphan-tree unit; five new registry mutants.
