about

nx_galx_thumb_migrate.nx -- SOVEREIGN move of the thumbnail cache from local disk to the NAS, so the thumbs live on the NAS (159TB) instead of eating local C:. For each CID in the view index it copies knowledge/store/galx-thumb/<cid>.png -> /mnt/nas_ai/_galx_thumbs/<cid>.png then unlinks the local copy. Idempotent: a CID already on the NAS is skipped. Uses ONE reused read buffer (no per-file mmap -> no leak, no fork needed). Run several instances over disjoint ranges (launcher) for parallel throughput; CIDs never overlap so there is no contention. Usage: nx_galx_thumb_migrate <start> <count>. license_tier: ORIGINAL
