modelvet 0.1.1

Verify-before-load structural validation for GGUF and safetensors model files

modelvet (Python binding)

Verify-before-load structural validation for GGUF and safetensors model files. ctypes binding over the modelvet C library: fixed memory, checked arithmetic, bounded work, no allocation inside the validator.

import modelvet

report = modelvet.verify_path("model.safetensors")
if not report.accepted:
    print(report.violation_name, report.violation, hex(report.offset))

A malformed file is a normal result: a Report with a REJECT verdict and the first precise violation, not an exception. Exceptions are reserved for API misuse (ModelvetArgumentError), arena exhaustion (ModelvetArenaError), and a missing native library.

An ACCEPT verdict is structural only: it says nothing about model behavior, provenance, or poisoned weights. See the project's INTEGRATION.md for the full contract.

Native library resolution

1. MODELVET_LIBRARY (path to a shared library; make shared in the repository builds build/libmodelvet.so),
2. the packaged modelvet/_native module built from the vendored amalgamation at install time,
3. a system libmodelvet found by ctypes.util.find_library.

If the library was built with raised MVET_MAX_* caps, set MODELVET_ARENA_BYTES to at least its recomputed worst-case bound.
