OxiFFT 0.4.2 fixes a wrong-answer bug (not a precision bug) in the x86_64 SSE3 SIMD butterfly kernel that every non-AVX2 x86_64 CPU takes — a wrong complex-multiply lane order and twiddle-recurrence drift together failed 93 of 1447 tests by 10-100x the tolerance. Found by running the suite on x86_64 for the first time. Plus a Miri-driven pointer-provenance fix, four new soundness hardenings against attacker-influenceable wisdom strings, and a fuzz-harness tolerance bug of its own. Pure Rust FFT, no FFTW.
OxiArc 0.3.5 rewrites the -lh4-/-lh5-/-lh6-/-lh7- codec from a private bitstream format into genuine canonical LHA wire format, validated against real third-party .lzh archives and a live lha (Lhasa) CLI oracle. Also fixes a Miri-flagged CRC UB class, three writer resource leaks, and a CLI exit-code bug. 1,878 tests passing, Pure Rust.
