- topology.svg, container-tree.svg, data-flow.svg: show /srv/nc-files bound directly into nextcloud container at /mnt/ncdata (no intermediate /mnt/nc-data/nextcloud-data layer). - architecture.html: explain rewire, update storage table, remove pre-rewire 'why two layers' section. - procedure.html: NEXTCLOUD_DATADIR=/srv/nc-files, no mastercontainer bind, add §2.5 Rewire 2026-08-11 with recovery procedure, update backup script to also tar local nextcloud app volume, fix 4.3 verification (302 -> /login, status.php, file visibility). - operations.html: 4 backup files now (added aio-nextcloud-app.tar.gz), restore procedures updated, single-file restore uses new tar layout. - troubleshooting.html: add 3 new sections — appdata-missing, nextcloud-not-spawning, collabora-discovery-warning. - request-flow.svg: remove nextcloud/ subdir from NFS write path. - index.html, README.md: update paths and metadata.
