The runs monitor folded every load failure into 'hub not reachable',
contradicting the sidebar's green connected dot whenever the hub
answered but the RPC failed — most visibly against a pre-0.22 hub
whose version predates the ListInvocations RPC (UNIMPLEMENTED).
Classify the failure instead (top-level, unit-tested):
- UNIMPLEMENTED -> 'this view needs a newer hub version' with a
doctor-page link (the update banner lives there)
- FAILED_PRECONDITION from the detached gate -> the regular
feature-off empty state with the guide button
- UNAVAILABLE / DEADLINE_EXCEEDED / socket-level failures -> the
honest 'hub not reachable' state (unchanged)
- everything else -> a load-failed state with the friendly error
and a copyable detail box
The error view is a public callback-driven widget so the tests pump
each variant without a live hub. New DE+EN strings for the too-old
and load-failed states; grpcCodeOf/grpcMessageOf exposed from the
friendly-error mapper instead of duplicating the duck-typing.

The empty state unconditionally claimed background runs were
switched off, even on hubs where the operator had enabled them.
The hub now reports the flag on the list RPC (detached_enabled);
the hint picks the truthful variant.

The empty state explained itself in operator jargon (detach,
detached.enabled, operator config) and offered no way forward.
Now it says what background runs are in everyday language and
opens the built-in guide — which carries the exact activation
steps — via a real button. DE and EN.

New Runs sidebar destination listing detached invocations (detach:true)
with phase, current step, project and a Cancel button while
pending/running. Workspace-scoped like Audit/Approvals, polls every 2s.
Detached runs are opt-in (detached.enabled) — the empty state explains
how to enable them. Inline help doc DE+EN. DetachedRun model +
listDetachedRuns/cancelDetachedRun in HubService, backed by the SDK's
listInvocations()/cancelInvocation(). flutter analyze clean; 29 tests
green (sidebar Y-stability updated for the new destination, model
mapping unit-tested).
Screenshot verification (light+dark) deferred — shared desktop in use.
