mapreduce-skill

MapReduce root/orchestrator with a mandatory parallel Verify phase, narrative-first reduction, deterministic artifact lifecycle management (.rlm run/archives), and concurrency safety (per-run locks + cleanup lock). Use when coordinating many parallel map-worker tasks under optional hint_paths, then synthesizing narrative reports into a decision to iterate or finish.

Contract-based MapReduce worker for executing a task (may be broad) under optional hint_paths, producing a narrative report. Use when an orchestrator invokes a map worker (llm_query role) many times in parallel and needs mergeable narrative reports.
