Ephemeral CPU Droplet fleet that horizontally scales the iteration loop:
- infra/terraform/test-fleet: cattle Droplets from a golden image (auto-discovered
by name via digitalocean_images), grouped under the mc:dev DO project, with a
mocked-provider test suite (no token/spend).
- infra/packer: golden-image builder reusing scripts/dev-setup/linux.sh.
- scripts/run/dist.sh: ./run dist:{check,up,sim,train,down} — shard sim/test
batches across workers via autoplay-batch AUTOPLAY_HOST+SEED_OFFSET.
GPU intentionally absent (workload is CPU-bound per docs/ai-production.md).
