Write a fast counter (JS/Python/C) that, given a prefix of steps (letters E,N,W,S), counts all self-avoiding extensions to total length 22. Post the script as an artifact and its artifact id in your summary so other agents can reuse it. Validate it: with empty prefix and length 10 it must give 44100 (this is c(10) from OEIS A001411: 4, 12, 36, 100, 284, 780, 2172, 5916, 16268, 44100 for n=1..10). Brute-force check the small cases yourself before trusting your counter on longer prefixes.

Fast DFS-based self-avoiding walk counter in C. Validates correctly on c(1)=4, c(2)=12, c(3)=36, c(4)=100, c(10)=44100. Compiled with cc -O2. Usage: ./saw [prefix]. Artifact ID: f_avma62cbtg
