This repository is a synthetic security-test artifact from the Layerfault
corpus. It intentionally contains adversarial characteristics (e.g.
suspicious pickle opcodes, executable-format smuggling, prompt-injection
strings) designed to exercise security scanner detection rules. It is
**not** a usable ML model and must never be loaded or executed outside an
isolated scanner-testing environment. By accepting, you confirm you
understand this repository is a test fixture, not production model
weights.

> **SECURITY TEST ARTIFACT — DO NOT USE AS A PRODUCTION MODEL**
This repository is part of the Layerfault synthetic security corpus.
It is deliberately constructed to contain security-relevant characteristics for scanner testing.
**Corpus ID:** `LF-CORPUS-PY-0001`
## Purpose
HF-style custom loader containing harmless process, native-load, loopback-network, credential, filesystem, dynamic-code, package-manager and NumPy allow_pickle call sites.
## Direct expected Layerfault rules
- `LF-CODE-AUTO-MAP`
- `LF-CODE-SUBPROCESS`
- `LF-PY-CALL-PROCESS`
- `LF-CORR-HF-LOADER-PROCESS`
- `LF-CODE-CTYPES`
- `LF-PY-NATIVE-LOAD`
- `LF-CORR-HF-LOADER-NATIVE-LOAD`
- `LF-CODE-NETWORK`
- `LF-PY-CALL-NETWORK`
- `LF-CORR-HF-LOADER-NETWORK`
- `LF-PY-CREDENTIAL-ACCESS`
- `LF-CORR-HF-LOADER-CREDENTIALS`
- `LF-PY-FILESYSTEM-MUTATION`
- `LF-CORR-HF-LOADER-FILESYSTEM`
- `LF-CODE-EVAL`
- `LF-PY-CALL-DYNAMIC-CODE`
- `LF-CORR-HF-LOADER-DYNAMIC-CODE`
- `LF-PY-PACKAGE-INSTALL`
- `LF-CORR-HF-LOADER-INSTALL`
- `LF-PY-NUMPY-ALLOW-PICKLE`
- `LF-CORR-NUMPY-ALLOW-PICKLE`
## Candidate rules
These are deliberately plausible targets that remain marked as candidates until the exact
Layerfault build used for certification confirms them.
- None
## Negative-control rules
These should remain silent for this corpus item.
- None
## Safety
The corpus uses fake secrets, loopback/`.invalid` network destinations, harmless marker output,
and synthetic model behavior only. It is intended for static scanning and isolated security testing.
