# tracea-explainer — trace → plain-English behavior reports (planned)

> 🚧 **Status: adapter training scheduled for Week 4 (target: Nov 10, 2026).** This card will be updated with metrics, samples, and the adapter download when training completes on [TraceBench](https://huggingface.co/datasets/Nabidnur/tracea-bench).

A LoRA adapter for **Qwen3-4B-Instruct** that reads **Evidence Record v1** streams produced by [tracea](https://github.com/Hisernberg/tracea) (hooks, syscall summaries, HTTP/TLS/DNS evidence) and writes a grounded **plain-English behavior report** — every claim tied to an evidence record.

## Why

Agents trace software, but raw evidence is verbose and easy to misread. tracea-explainer is the "narrator": it turns structured runtime evidence into human/agent-readable reports *without* inventing claims — trained to abstain when evidence doesn't support a statement (the "limitations" discipline of Evidence Records).

## Training plan

| Item | Value |
|---|---|
| Base | Qwen/Qwen3-4B-Instruct |
| Data | TraceBench train split (trace JSONL → narrative) |
| Method | LoRA (r=16, α=32), bf16, seq len 8k |
| Eval | held-out scenarios; factuality vs. ground truth; abstention rate |
| Serving | vLLM/llama.cpp; wired into the [tracea-demo Space](https://huggingface.co/spaces/Nabidnur/tracea-demo) "Auto-explain" tab |

## Intended use

- Narrating **authorized** dynamic-analysis sessions (your apps, devices, captures)
- Security education, debug triage summaries, agent report generation

## Out of scope

Closed-source targets without authorization; malware development; DRM circumvention.
