The widget suites used to talk to whatever listens on the real endpoint — results depended on the operator's machine (a running hub fed real data into a11y/responsive runs and its gRPC channel timers caused the historic flake). Hardening round: - HubService.instance is now injectable (debugSetInstance); FakeHubService (test/support/fake_hub.dart) answers every member the pages touch with healthy-empty defaults and scripts per-RPC failures (UNIMPLEMENTED / UNAVAILABLE / detached gate) through a GrpcError-shaped fake. Unimplemented members are recorded and fail the sweep with the exact list. - state_matrix_test.dart pins the app-wide invariants for every sidebar page x hub condition: healthy => no unreachable claims and no raw error text; hub gone => honest unreachable states; UNIMPLEMENTED => never 'not reachable' while the sidebar shows connected; detached gate => plain-language feature-off state. - a11y + responsive sweeps now inject the fake (hermetic); the 6-minute idle-timer drain workaround is gone with the cause. Real bugs the new sweep caught immediately: - every data page (store, doctor, audit, approvals, federation) folded ANY load failure into 'hub not reachable' — the runs-page bug class; they now share HubLoadErrorView, which classifies into unreachable / needs-newer-hub / load-failed-with-copyable- detail (new generic DE+EN strings) - the approvals page's hidden tab had no future listener: a load failure there surfaced as an uncaught async error - the audit status bar rendered the raw gRPC error wall verbatim; it now shows the classified friendly headline (still selectable) Signed-off-by: flemming-it <stefan.a.flemming@googlemail.com>

// HubLoadErrorView — the one way a page presents "my content
|
|
// could not be loaded". Pages used to open-code a "hub not
|
|
// reachable" empty state for ANY failure, contradicting the
|
|
// sidebar's green connected dot whenever the hub answered but the
|
|
// RPC failed (an older hub without the RPC, a feature gate, a real
|
|
// bug). This widget routes the failure through the shared
|
|
// classification instead:
|
|
//
|
|
// * unreachable -> the honest "hub not reachable" state
|
|
// * unsupported -> "this view needs a newer hub version"
|
|
// * other -> "could not load" + the friendly error in a
|
|
// copyable detail box (hard rule: errors are
|
|
// always copyable)
|
|
//
|
|
// The state-matrix suite pins the behaviour across every page.
