Symptom: when a described microflow contained repeated implicit output variables at the same canvas position, rebuilding the MDL could reuse the first variable name for later activities and make downstream changes or returns point at the wrong object. Root cause: the builder tracked variable declarations by name only and did not distinguish same-position duplicate implicit outputs that need a deterministic local alias. Fix: record implicit output positions, assign numeric aliases such as `Foo_2` for same-position collisions, and resolve downstream variable references, attribute paths, change targets, and retrieve start variables through the active alias. Tests: added a builder regression for duplicate create-object outputs, added a doctype fixture, and documented the aliasing rule in the proposal index and quick reference.
