# ── CodeScene Code Health gate ────────────────────────────────────────────

# Thresholds are a ratchet — only go up, auto-updated after each successful push.
# Note: remote scores lag behind local changes (update after push + re-analysis).
# If check fails: extract hooks, split components, reduce complexity.
# Never use eslint-disable, #[allow(...)], or `as any`.
