 - Merge gates, run before merging — each asks what no other gate asks: `uv run --no-sync python3 scripts/check-vote-count.py` (approvals still valid) · `scripts/check-pr-base.py` (base reaches master) · `scripts/check-merge-freshness.py` (that green CI is about the landing tree) · `scripts/check-merge-order.py` (dirt and what it lands) · `scripts/check-merge-landing-diff.py` (what the landing changes) · `scripts/check-merge-pairs.py` / `scripts/check-merge-sequence.py` (a pair, or a whole order) · `scripts/check-merge-tree-health.py` (the merged tree passes one guard) · `scripts/check-merge-plan-suite.py` (the plan's final tree passes the suite) — all under `uv run --no-sync python3`
 - Post-merge audit: `uv run --no-sync python3 scripts/check-merge-landed.py <N>` (did the merge land a tree its reviews named)
