+"""Skill write-origin provenance — ContextVar for distinguishing agent-sediment skill writes from foreground user-directed writes.
+
+The curator only consolidates/prunes skills it autonomously created via the
+background self-improvement review fork. Skills a user asks a foreground

+This module exposes a ContextVar that run_agent.py sets before each tool
+loop so tool handlers (e.g. skill_manage create) can check whether they
+are executing inside the background-review fork.
+
+The signal piggybacks on AIAgent._memory_write_origin, which is already
