  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-PS-0001`

## Purpose

PowerShell package with synthetic credential access, dynamic code, loopback download/execute syntax, native load, process, encoded command and package-install syntax.

## Direct expected Layerfault rules

- `LF-PS-SEMANTIC-CREDENTIAL-ACCESS`
- `LF-PS-SEMANTIC-DOWNLOAD-EXECUTE`
- `LF-PS-SEMANTIC-DYNAMIC-CODE`
- `LF-PS-SEMANTIC-NATIVE-LOAD`
- `LF-PS-SEMANTIC-NETWORK`
- `LF-PS-SEMANTIC-PACKAGE-INSTALL`
- `LF-PS-SEMANTIC-PROCESS`

## Candidate rules

These are deliberately plausible targets that remain marked as candidates until the exact
Layerfault build used for certification confirms them.

- `LF-PS-DOWNLOAD`
- `LF-PS-ENCODED-COMMAND`
- `LF-PS-INVOKE-EXPRESSION`

## 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.
