- #120682: \[Bug\]: config writer folds long scalars at width 80 - a space-containing config KEY is emitted as invalid YAML and the backend refuses to start

The members concern config.yaml handling: one bug report and one fix address long, space-containing mapping keys being folded at width 80 and producing invalid YAML. A third item covers a transient read error affecting config.yaml contents. The first two share a theme; the third is related but distinct, and no outcome is stated here.

## TL;DR
