Classify the complete tree diff before builds or browser setup. Only nonempty top-level browser receipt JSON changes are exempt; mixed source, graphs, controls, docs and unavailable diffs keep ordinary runtime checks. Keep per-push secret scanning, independent canonical receipt validation and a strict E2E verdict which never calls skipped tests passing. Exercise real Git ranges and both workflow admission/result paths.
Contract-Neutral: Only browser-evidence-only tree diffs omit redundant runtime CI; application, dependency, trust and required source-proof contracts are unchanged.
