The caveat said "~58 GB free" as a flat number, but preflight_lmcache_ram actually hard-fails the launch unless MemAvailable >= L1 + 28 GB (the +28 covers vLLM + OS), computed from the live L1 so it tracks the LMCACHE_L1_GB override (l1=10 -> ~38 GB). The static Requires-min-ram-gb: 58 header is documentation only — nothing in scripts/ reads it; the guard keys off the lmcache-l1-gb header. Also note the gate is --force-proof.
