Why: Allow consumers to download an immutable module revision without nested source checkouts or local path replacements. Evidence: SELF package tests and the prior canonical-path rejection are recorded in the Dev dependency-workspace task card; remote consumption is replayed against the committed candidate. Impact: Change the module identity and its Go imports while preserving API behavior. Existing historical submodule revisions remain buildable.
