hello in your manuals I found link to the folowing repository: https://salsa.debian.org/live-team/live-images/ but this sources are looking very outdated.for example, the 'debian' branch, which is the newest, was updated in 2020, but debian bullseye was released in 2021.
is it means that those sources are not adopted for risent debian versions?what sources are used for official and unofficial debian bullseye live images?
