Attach cached JavaScript bytecode sidecars to HTTP response headers so WebContent can materialize classic and module scripts directly from a decoded cache blob on cache hits. Carry the disk cache vary key with the sidecar and reuse it when storing fresh bytecode, avoiding mismatches against the augmented network request headers used to create the cache entry. Keep CORS-filtered module responses intact for status, MIME, and script creation checks. Read bytecode sidecar data only from the internal response, and treat decode or materialization failure as a cache miss that falls back to normal source compilation.
