  "summary": "Static review, from supplied measurement evidence only, of what in a TypeScript program graph costs measured build or editor time: project references, composite/incremental/.tsbuildinfo behavior, generated-code volume, pathological type instantiation, and duplicated checking across lint, test, and build. Reads measurement output and configuration only.",

  "security_notes": "Static review of supplied measurement evidence only — reads `--diagnostics`/`--extendedDiagnostics` output, `--generateTrace` traces, `tsconfig.json` files, and package topology; never invokes the compiler, runs a build, or measures a live system, and never requests secrets, credentials, or customer data. Never prescribes a restructuring without a supplied measurement, and always records which compiler binary produced it.",
