Replace the proposed Ray cluster worker role with a dedicated local
AI agent for BlenderMCP 3D avatar creation (supporting ADR-0062).
waterdeep's Metal GPU provides hardware-accelerated rendering in
Blender — far superior to Kasm's CPU-only DinD environment. The
Ray cluster GPU fleet is fully allocated and stable; adding MPS
complexity is not justified.
Also adds cross-reference from ADR-0062 to ADR-0059.
gravenhollow RustFS is already S3-compatible — expose it through
the existing Cloudflare Tunnel with a dedicated HTTPRoute at
assets.daviestechlabs.io. Cloudflare CDN caches at edge PoPs.
Eliminates: R2 bucket, rclone sync CronJob, R2 API token, and
6-hour sync delay. Single source of truth on gravenhollow.
