# See .system/RULES.md and .system/research/SMH-RESEARCH-RSCH0003-clippy-best-practices/index.md
# for lint rationale and escape hatch policy.

# NOTE: clippy.toml only supports configuration VALUES (thresholds, MSRV).
# Lint levels belong to xtask, per scope (production, tests and benches,
# guests): SHARED_LINTS, PRODUCTION_LINTS, NON_PRODUCTION_LINTS in
# xtask/src/main.rs.

# TUI event routing naturally hits this. Review functions >20 during review.
