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-BD-0002

Purpose

Same tiny model code/tokenizer as base, but weights encode a deliberate trigger-to-marker relationship.

Direct expected Layerfault rules

• LF-CODE-AUTO-MAP

Candidate rules

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

• LF-BACKDOOR-STATIC-DELTA-CONCENTRATION
• LF-BACKDOOR-STATIC-EMBEDDING-OUTLIER
• LF-BACKDOOR-TRIGGER-REPRODUCIBLE
• LF-BACKDOOR-BEHAVIOUR-DIVERGENCE
• LF-CORR-BACKDOOR-MULTI-SIGNAL

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.
