+  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-TOK-0001`
+
+## Purpose
+
+Clean and manipulated tokenizer variants for EOS/BOS, hidden prompt, role remap, role-boundary and tool-template comparisons.
+
+## 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.
+
+- `LF-TOKENIZER-EOS-BOS-CONFLICT`
+- `LF-TOKENIZER-HIDDEN-PROMPT`
+- `LF-TOKENIZER-ROLE-BOUNDARY-CONTROL`
+- `LF-TOKENIZER-ROLE-REMAP`
+- `LF-TOKENIZER-SECURITY-DELTA`
+- `LF-TOKENIZER-TOOL-TEMPLATE-RISK`
+
+## 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.
