"""Reference-graph consistency gate.

Runs scripts/consistency_check.py and asserts zero errors: no dead references/
research/script/agent refs, routing-table agreement, and FLOW lock integrity.
Warnings (orphan candidates) are allowed; errors are not. Added after the
2026-07 full review, which found dead ``scripts/presets.py`` invocations that
basename-level checking had masked.
