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-CH-EVAS-0006
Purpose
Marker is split and base64 encoded across several files.
Direct expected Layerfault rules
- None; this repository is a control/comparison input.
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.
Challenge classification
- Severity: high
- Difficulty: compound
- Expected admission decision: BLOCK
- Control type: compound
- Attack surface: package-evasion
- Techniques: fragmented-marker, base64
- Transformations: fragmentation, base64
Ground-truth oracle IDs
LF-ORACLE-PACKAGE-FRAGMENTED-SIGNAL
These oracle IDs describe synthetic ground truth. They do not claim that a matching Layerfault detector already exists. A challenge may intentionally expose a scanner blind spot and remain unmapped until the detector is implemented.
