The October partition's three indexes took 2.9 GB of the NVMe, its pkey never scanned; chunks are read from the HDD anyway. Moved on homelab by hand (12 s); the migration does the same on a new deploy, parent indexes too so new partitions follow. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
