 - Reserve a separate small storage budget for `Redis` on `sol`, initially `2 GiB` unless persistence requirements change.
 - Prefer a dedicated path such as `/srv/trade/postgres` and `/srv/trade/redis` over implicit storage under `/var/lib/rancher/k3s/storage`.
 - On the current `btrfs` root filesystem, the preferred implementation path is a dedicated subvolume plus enforced `qgroup` quota for each persistent component.
+- Done on `2026-04-12`: created `btrfs` subvolumes on `sol` at `/srv/trade`, `/srv/trade/postgres`, and `/srv/trade/redis`.

 - Target hard quota for `Redis` on `sol`: `2 GiB` unless later requirements justify persistence growth.
 - Keep enough unallocated free space on the root NVMe for the OS, `k3s`, container images, logs, and rollback operations after trade quotas are reserved.
+- Done on `2026-04-12`: enabled `btrfs` qgroups on `/` at `sol` and applied hard quotas of `1 TiB` to `/srv/trade/postgres` and `2 GiB` to `/srv/trade/redis`.
