core: one tunnel for two strates with landing chambers (L151, owner design; v238, grade open)

Browse Source 
Each passage records upper and lower landing chambers (floor, gradient, radius, 4.5 m clear height) composed with the
tunnel shell; cave route endpoints bind to the chambers; envelope audit permits only the named chamber joints.
Seed 2: 0 solid in 319,579 passage+chamber capsule samples, 0 shell violations, 0 envelope conflicts, controls fire.
Open: tunnel-to-chamber floor blend leaves 19.1/19.0 deg grades (limit 15); sweeps/timing not run.
