v0.1.0 — MVP signature corpus + applier

First public release of opensig: open, clean-room library signatures for stripped static ELF binaries, with a Ghidra headless applier.

Highlights

• glibc 2.41 (Debian + source -O2/-O3) and musl 1.2.5 (gcc -O0/-O2/-O3, clang -O2) packs
• Relocation-masked patterns + call-graph confidence scoring
• opensig detect|match|apply|check CLI

Benchmark (Ghidra 12.1.4, stripped static gcc -O2 test binary)

Named before	38 / 1085
Named after	855 / 1109
Precision vs unstripped	97.3%
Precision at confidence ≥ 0.8	100% (688/688)

Assets

• opensig-0.1.0-sigs.tar.gz — all packs under sigs/ (also present in the tag tree)

Clean-room

Signatures built only from open-source / distro archives. No IDA FLIRT, Lumina, Binary Ninja, or other proprietary signature data.
