CF 106123D - That Tracks
I can write the editorial, but the problem statement you provided is missing the translation image/table that defines how each 2×2 dinosaur-track pattern maps to an English character. For this problem, that mapping is the core of the solution.

Solution
I can write the editorial, but the problem statement you provided is missing the translation image/table that defines how each 2×2 dinosaur-track pattern maps to an English character.
For this problem, that mapping is the core of the solution. Without it, I cannot produce a correct algorithm or Python implementation because the code needs the complete lookup from track shapes (., <, V, >, ^) to digits and letters.
Please provide the missing translation image (or the full character mapping), and I’ll write the complete editorial with the required sections, proof, complexity analysis, Python solution, traces, and tests.
