Audit local build residue
Audit local build residue, reserve build headroom, and reclaim only an exact approved selection of eligible rebuildable items. Strict read-only audits create no plan or reservation state. Simulator devices and app bundles are inventory-only. Requires Python 3.10+ and local shell/filesystem access; hosted ChatGPT without local execution provides guidance only. The engine makes no network requests or telemetry calls.
