Name the fill condition for buckets and logs, and judge each one on its own

Review of #231: "store" is the glossary's word for the postgres server, so
the condition is bucket-or-log-filling. And one stream that cannot be read
no longer fails the whole check: it is said as unread with its reason, an
open fill condition for it is kept, and every other bucket and log is
still judged (ADR 0297 §6).
