README.md:227 and examples/zarr_volume_access.py:35 open s3://vesuvius-challenge-open-data/PHerc0332/volumes/20231201141544-3.240um-70keV-masked.zarr/ That prefix is not in the bucket (HTTP 404 on .zattrs); the catalogue publishes that 2023 volume under https://data.aws.ash2txt.org with a samples/ prefix. The documented quickstart therefore fails on first run. Switched both to PHerc0332/volumes/20251211183505-2.399um-0.2m-78keV-masked.zarr/, the PHerc0332 volume actually in the bucket (HTTP 200 on .zattrs and 0/.zarray).

Motivation.
README.md:227andexamples/zarr_volume_access.py:35openThat prefix is not in the bucket —
.zattrsreturns HTTP 404 — because the catalogue publishes that 2023 volume underhttps://data.aws.ash2txt.orgwith asamples/prefix, not under the S3 root. The documented quickstart therefore fails on first run.Before:
After — the PHerc0332 volume that is actually in the bucket:
Two lines changed; same volume family, code otherwise identical. Found while auditing the catalogue against storage (https://github.com/dud8/catalog-lint).
