    Interface QueueDiagnosticsBatch

    One page of queue observations across every registered queue source (M98f), as the diagnostics connector serves GET /v1/queues.

    state is unsupported when no queue source is registered (or the client negotiated no queue inspector), otherwise ready — per-source states are in sources. after/next/lost follow the M98a cursor contract over the connector's merge ring; lost counts only MERGE-ring eviction, while each source's own eviction is reported in its status. truncatedSources counts registered sources beyond the fixed 16-source bound that are never read, and truncatedDepths the depth observations omitted to keep the frame within its fixed 256 KiB budget. With those four counters a consumer can always say what it did not see.
