	# Hard ceiling for any single Elixir source file under elixir/lib/.
	# Rationale: anything north of ~800 LOC is a refactoring smell. The
	# repo's own CLAUDE.md flags ">600 mandatory split" — we use 800 to
	# absorb the realistic post-split tail (helpers + types + specs).
	# Bumped 800→850: orchestrator.ex absorbs Gate D result handler
	# until a dedicated GateResultHandler sibling is extracted.
	# 850 restored after SYM-18 extracted AgentExit sibling
	# (PR #178, commit pending).
