A vehicle is admitted without sufficient surveyed clearance · case 05
A vehicle is admitted without sufficient surveyed clearance in the controlled route-policy fixture.
Case contract
All dimensions are integer centimeters. Unknown clearance is None and rejects travel; equality with height plus margin permits travel.
Why this case matters
Navigation policies depend on road context that a shortest-path cost alone does not encode.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
