Changed functions from recent fix-like Redis commits. Position comes from normalized AST deltas; source and AST evidence load only when selected.

This first map samples recent commits whose subjects explicitly look like repairs. It compares each changed function before and after, measures the fraction and boundary of its changed syntax, and projects the deltas at exact, operation-bound and shape-only levels. Similar positions are hypotheses to inspect in the attached source—not proof that two bugs had the same cause.
