Three fixes from the first deploy attempt on irv-ml1: - build.target=production. Upstream Dockerfile is multistage; the last stage `cpu-base` was selected by default, producing a CPU-only image with no flash-attn and `torch ... whl/cpu`. - user: "0:0". Upstream image declares USER appuser but writes runtime state under /root (mode 0700). appuser cannot traverse /root, so /v1/voices 500s on PermissionError. Run as root to sidestep. - QWEN3_TTS_MODEL=Qwen/Qwen3-TTS-12Hz-1.7B-CustomVoice. The bare `1.7B` id we had isn't a real HF identifier; upstream publishes -CustomVoice / -Base variants of each size. Use -CustomVoice so `voice="clone:<name>"` works. Tag bumped to v2 to keep the v1 cpu image distinguishable in the local registry. After: all 5 verify steps pass, GPU synthesis ~5s for 3-4s of audio, three contrasting English `instructions` produce three distinct hashes — emotion steering actually works (unlike CosyVoice's English path).
