test vectors
known-answer test values for tropical operations. placeholder — to be populated with concrete F_p test cases.
scope
element operations: tmin, tmax, tropical mul, sentinel handling
matrix operations: matmul, power, Kleene star
eigenvalue: small cycle graphs with known critical cycles
determinant: small matrices with known optimal assignments
encoding: round-trip F_p ↔ tropical, sentinel preservation
edge cases: +∞ inputs, zero matrix, identity matrix, overflow saturation
