Productionizes yesterday's seed-variance finding. Wraps
emotional_speech.sh, rolls a list of seeds, scores each via
quality_eval (speaker_cosine + Moonshine WER), and copies the
lowest-WER candidate to --out. Defaults to 5 seeds; pass
--seeds 42,7 for cheaper runs.
Tie-breaking is `min(WER), then -max(cosine)` — text fidelity
takes precedence over speaker character because user-typed text
should be rendered verbatim, while voice character is only
secondary on top of context conditioning. Failed generations
(short clips that get the -1 cosine sentinel) sort to the bottom.
Smoke run on the canonical "Today I want to share..." prompt:
seed 7 → cos 0.845, WER 0.714 "Today, today I want to share..." ← picked
seed 100 → cos -1, WER 1.000 "It is." (premature EOT)
seed 42 → cos 0.916, WER 2.000 "The police are, if you're..." (drift)
Cost: N × single-shot cost. The recipe being unreliable per-seed
is the whole reason this wrapper exists — pay the multiplier in
exchange for a reliably-best output.
