# Runs all five gates required before the default-on merge can land.

# scripts/m7_ship_gate.sh [--nyx BIN] [--corpus-dir DIR] [--skip GATE,...]

# Gates:
|

# 1. unsupported-rate — per-cell (cap × lang) Unsupported% within budget

# 2. false-confirmed — false-Confirmed rate from telemetry ≤ 2% per cap

# 3. wall-clock — default scan ≤ 2× static-only on bench suite
|

# 4. sandbox-escape — sandbox escape suite green for all langs
