Tune NixCI: hand-specify dependencies, disable auto-discovery Automatic dependency discovery walks the derivation closures to infer ordering; on a no-op rebuild (every job already cached) that analysis is the only cost. Specify the graph by hand and turn discovery off so a no-op is as fast as possible, while still building the shared deps derivation before its consumers.
