+The WebUI polls this read-only projection every 15 seconds only while its page
+is visible. It permits one request at a time, stops the timer when the document
+is hidden, and performs one refresh when visibility returns. Runtime providers
+register through the Core contract; Ops itself does not import Celery, Redis,
+or module-owned job implementations. A local development profile may
+intentionally disable workers without becoming unready. A production or other
+non-development profile treats a disabled, unconfigured, stale, or unreachable
+provider as readiness-critical.

 work becomes part of normal operation:
