+**Note:** Bridge mode uses bucket definitions instead of the single `flood.retry.prefixes` target list. It also has an implicit unconfigured catch-all bucket. If a flood comes from one fresh configured bucket, retry continues until every other fresh configured bucket plus the catch-all bucket has been heard or `flood.retry.count` is exhausted. If a flood comes from an unconfigured or pathless source, retry targets every fresh configured bucket. This means one configured bucket bridges between that bucket and everything else. Prefixes in `flood.retry.ignore` never count as heard bridge targets.
