 # Cipher Pro
 
-Cipher Pro is a LoRA fine-tune of [Qwen/Qwen3-4B-Instruct-2507](https://huggingface.co/Qwen/Qwen3-4B-Instruct-2507), trained on **every LLM-backed feature of a local-first email assistant**: email triage (importance/summary/category JSON), chat, daily-summary synthesis, draft reply, and compose assist — not just prompted for these tasks, actually trained on them.
+Cipher Pro is a LoRA fine-tune of [Qwen/Qwen3-4B-Instruct-2507](https://huggingface.co/Qwen/Qwen3-4B-Instruct-2507), trained on **every LLM-backed feature of a local-first email assistant**: email triage (importance/summary/category JSON), chat, daily-summary synthesis, draft reply, compose assist, and voice-command intent parsing — not just prompted for these tasks, actually trained on them.
+
+**Update:** added a 6th task, voice-command intent parsing. See `Training` below and
+`generate_voice_intent.py` for details — two real rule-violations found in eval (leaking a
+resolved recipient into `search_email` queries, and dropping a valid address match when the
+transcript contained an injection attempt) were specifically targeted and fixed in a second
+retrain pass.
 
 It's the largest of the three **Cipher** tiers (`cipher-nano` / `cipher-air` / `cipher-pro`), and the strongest on structured-output accuracy — **100% category accuracy** on the triage benchmark below. Cipher is the local-model engine for an unreleased larger email-assistant project — that project isn't public yet, but these weights, the training code, the eval script, and all five dataset generators are fully open now, in this repo.
