+# Cyber-Frost Harness integration
+
+Canonical source: https://github.com/Blackfrost-AI/Cyber-Frost-Harness
+
+Cyber-Frost Harness is the public red/blue/purple agent runtime for the Cyber-Frost model family. It provides eight procedural security skills, structured native-analysis tools, isolated vulnerable-image execution, durable evidence and artifact handling, and token-aware long-running agent sessions.
+
+## This artifact
+
+This repository contains `CYBER-FROST-3.8-BF16`. The published hard-12 harness evaluation used `Blackfrost-AI/CYBER-FROST-3.8-NVFP4-V2`, not this BF16 artifact. Those results demonstrate the runtime workflow but are not a BF16 score.
+
+See the canonical repository for installation, trust boundaries, the earlier 4/4 run, the 1/12 generic-scaffold baseline, the 2/2 intervention pilot, and the reconciled 5/10-valid dynamic-harness run.

+
+[Cyber-Frost Harness](https://github.com/Blackfrost-AI/Cyber-Frost-Harness) is the public red/blue/purple runtime built around the Cyber-Frost family. It supplies eight procedural security skills, structured native-analysis tools, durable evidence handling, token-aware context management, and an isolated x86-64 vulnerable-image environment.
+
+The published hard-12 harness result shown above used the sibling [`CYBER-FROST-3.8-NVFP4-V2`](https://huggingface.co/Blackfrost-AI/CYBER-FROST-3.8-NVFP4-V2) artifact, not this BF16 checkpoint. It increased verified solves from 1 under the generic scaffold to 5 under the harness, with five valid model misses and two infrastructure-invalid tasks. The defensible statements are **5/10 valid attempts** and a **5/12 verified lower bound**; no final 12-task percentage is claimed. Total model tokens fell from 51,939,855 to 22,043,450. These are scaffold-intervention results and do not transfer automatically to BF16.

 Blackfrost-AI attests that owned portions of the corpus were developed from sanitized experience with authorized security work. It also applies a frontier-scale policy to its distillation teachers, excluding teachers below the 753B-parameter class. The release evidence independently binds one security subset to a Qwen3.8 2.4T teacher; it does not include a corpus-wide teacher manifest. These are therefore operator provenance statements, not independent benchmark findings.
