+-- PATTERN 6: Jumps and Merges — retry, error rejoin, crossed branches
+-- Source: the graph shapes a nested IF cannot express (mendixlabs/mxcli#923)
+-- Layout: a BACKWARD edge (the retry), two error handlers rejoining the main
+--         flow, two splits whose arms land on a shared merge, and a funnel
+--         where three independent paths end. Expected canvas: tall rather
+--         than wide, with lines running right-to-left across it.

+/**
+ * Synchronises one Factory's telemetry, with retry and a degraded fallback.
+ *
+ * Every join shape MDL can spell, in one flow:
+ *   - BACKWARD     the handler jumps back to `attempt`, above the call, so
+ *                  the failed call is retried until $MaxAttempts
+ *   - ERROR → MAIN a handler that gives up joins `degraded`, which the main
+ *                  flow also reaches when the response came back empty
+ *   - CROSSED      the inner split's FALSE arm and the outer split's FALSE
+ *                  arm both land on `review`, which no nesting of IF
+ *                  reproduces
+ *   - FALL-THROUGH the last handler ends without RETURN or JOIN, so it
+ *                  merges back into the main flow of its own accord
+ *   - FUNNEL       three independent paths end at `finish`
+ *
+ * Expected layout: `attempt`, `degraded`, `review`, `emit` and `finish`
+ * are merge nodes carrying two or three incoming lines each; the retry edge
+ * is the one that runs backwards.
