- internal/snapshot: compact cluster state via schedulerclient (nodes,
PEND top-N most-starved with parsed pending_reason, cluster sums, queue
garnish, recent exits). Field whitelists + stall-threshold filter keep
the state a few KiB. Module-local PEND-reason table mirrors
mcp-server/internal/pendreason.go (lift into schedulerclient is a P1
cleanup).
- internal/detect: pend_stall / worker_health / util_skew / exit_burst
triggers — threshold, then per-scenario cooldown, then dedup on a hash
of the situation (job set + reasons / node set) so an unchanged cluster
is never re-evaluated.
