 5. **Colour** — Dross is **violet** by default, but his accent is **tunable in Settings** (his own vars, independent of the UI theme).
 6. **Persona** — give him the real Cradle-Dross voice (dry, sardonic, impatient, brilliant, secretly loyal) via an **editable system prompt in Settings** (tunable).
 7. **Voice** — record a clip → transcribe with **local faster-whisper on the Ollama box (CT 102, GPU, CPU-fallback)** → transcript lands in the input for **review-and-send first (mode 1)**. A *voice-mode* setting allows graduating to **hands-free auto-send (mode 2)**, then **interpret-into-confirmable-action (mode 3)** later.
+8. **Audio retention (Phase 2, added 2026-06-09)** — by default the clip is transcribed then **destroyed** (transient). Add a **Dross setting** "Keep voice clips" that, when on, **saves each audio clip paired with its transcript**, stored **safely and securely** (encrypted at rest / access-controlled; on a homelab dataset, owner-only — exact store TBD in P2: e.g. a `voice_clips` table + blob on a ZFS dataset, or object store). Off by default. This is a P2 deliverable, designed-for now.
