"""Part B spike — does the controller tolerate a top-level `update_ladder:` key in .felhom.yml?

The drill catalog's navidrome carries the block (drill commit given as argv[1]). The app must sync,
deploy, probe and badge exactly as without it. Positive observables: the sync reaches the drill commit,
the metadata the page needs is read (display_name, deploy_fields), the deploy reaches `running`, the
controller's own health-probe line for navidrome appears, the badge renders in both languages."""
