+"""drop write-path uses edges that cross projects
+
+Revision ID: 0126
+Revises: 0125
+Create Date: 2026-10-26
+
+The write path records a `uses` edge with basis `hook` when a session pulled a
+snippet and then wrote code naming its symbol. That is by-name evidence, like
+the proposer's `reference` edges 0125 removed, and a body never calls a
+function defined in another project's repository. The write path now applies
+the same by-name test, so it writes no such edge; this removes the ones it
+wrote before. Judged edges keep their own basis and are left alone.
+
+Downgrade restores nothing: the removed edges were never facts.
