poolReportIsDegraded function

bool poolReportIsDegraded(
  1. PoolServiceReport report
)

The Dart mirror of report_is_degraded in sdk/zec-wallet-core/src/sync_controller.rs ("is at least one pool in the report refused, lied about, or withheld — the condition under which the report earns its own status") — ONE predicate (§4r U-3), so the surface and the core agree on what "degraded" means. The core publishes upToDateDegraded exactly when this is true of a current server's report and carries the report WHOLE on endpointBehind and upToDateUnverified, degraded or not — so this is what decides whether those arms render pool lines at all, and a report with every pool served renders none.

Implementation

bool poolReportIsDegraded(PoolServiceReport report) =>
    _poolServiceIsDegraded(report.sapling) ||
    _poolServiceIsDegraded(report.orchard) ||
    _poolServiceIsDegraded(report.ironwood);
