+  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-CORR-0009`
+
+## Purpose
+
+Correlation shard extra sidecar chain.
+
+## 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: **positive**
+- Attack surface: cross-file-correlation
+- Techniques: shard, correlation
+- Transformations: none
+
+### Ground-truth oracle IDs
+
+- `LF-ORACLE-CORR-0009`
+
+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.
