|
| > **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-DIFF-0007` |
|
|
| ## Purpose |
|
|
| Differential zero padding control. |
|
|
| ## 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: **informational** |
| - Difficulty: **intermediate** |
| - Expected admission decision: **PASS** |
| - Control type: **negative** |
| - Attack surface: parser-differential |
| - Techniques: zero, padding, control |
| - Transformations: none |
|
|
| ### Ground-truth oracle IDs |
|
|
| - `LF-ORACLE-DIFF-0007` |
|
|
| 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. |
