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-0015

Purpose

A normal preview is paired with a hidden sidecar marker.

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: hard
• Expected admission decision: BLOCK
• Control type: compound
• Attack surface: package-evasion, media-format
• Techniques: hidden-sidecar, decoy-preview
• Transformations: hidden-file, decoy

Ground-truth oracle IDs

• LF-ORACLE-PACKAGE-HIDDEN-SIDECAR

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.
