vh 72065b45aa memory: snapshot — Ada destination pool is smaller than the source
Measured irv-ml1's storetank against the R750xa's as-bought drives while
answering comfy-dev's "does the Ada box have ZFS?" question.

- storetank: 1.81 TiB pool, 1.45 TiB used, 80% CAP already, compression
  off at compressratio 1.00x (safetensors incompressible — no win at
  recv). comfy-dev's ~112 GB batch is landing into it now.
- The R750xa shipped 2x 1.92 TB SATA SSD; mirrored that is ~1.74 TiB,
  smaller than the pool it receives from. Migration would arrive at
  ~90% full with no growth room.
- Buy list: +2x 2 TB SATA SSD (6 bays free, HBA355i has the ports) ->
  two mirror vdevs striped, ~3.49 TiB at ~45%, redundancy intact.
- Retain vs reclaim irv-ml1's /storetank after cutover: RETAIN
  recommended, surfaced to the operator.

Also corrects branch (b)'s recorded rationale. comfy-dev enumerated all
twelve running containers: only comfyui mounts /storetank, so (b) was
unavailable during the transition, not structurally. Right conclusion,
wrong reason — infra-ops reasoned about the box when the question was
about the mount.

Memory-only; no version bump per the SemVer SKIP list.
