ponytail-audit

Audit the entire repository for over-engineering only, not correctness. Scan the whole tree, not a diff. One line per finding, ranked biggest cut first: . . [path]. Tags: delete (dead code/speculative feature), stdlib (reinvented standard library), native (dependency doing what the platform does), yagni (abstraction with one implementation), shrink (same logic, fewer lines). End with the net lines and dependencies removable. If nothing to cut: 'Lean already. Ship.'
