Squash the current repository state back into one baseline commit while preserving the README reframing and repository contents. Constraint: User explicitly requested a single squashed commit with subject "asdf" Confidence: high Scope-risk: broad Reversibility: clean Directive: This commit intentionally rewrites published history; coordinate before future force-pushes Tested: git status clean; local history rewritten to one commit; force-pushed main to origin and instructkr Not-tested: Fresh clone verification after push
