This document records the archived prototype/source-bundle target. The clean reconstruction has commits 1 through 10, including the separation of public metadata identity from implementation/link transport. Its historical phase checkmarks do not claim that the reconstructed tree has completed full span ownership, source ownership, or source-bundle work. In particular, Cargo and Buck source-bundle production and staging remain follow-up work.
