DeepSeek Harness watchdog plugin: detects truly stalled agent turns (never killing in-progress tasks — in-flight operations are exempt), nudges/terminates only on real silence, records every event to JSONL with a loopback status route
DeepSeek Harness task-protection plugin: preflight scanner (catches missing inject declarations that crash the host), loop detection, recursion guard, and interruption awareness with a safe-restart helper. Never terminates tasks.
