Carry received HTTP reason phrases from the parser through buffered and streaming responses, disk and memory caches, page responses, Fetch, and XHR. Preserve custom and empty HTTP/1 phrases and report empty text for HTTP/2 and HTTP/3. Synthesized responses retain canonical fallback. Regressions cover whitespace, non-ASCII bytes, and cache round trips.
Carry raw response header values through fetch, caches, redirects,
renderer delivery, workers, and protocol records. Convert explicitly
at WebIDL and protocol text boundaries while preserving opaque bytes.
Keep legacy CacheStorage and service worker metadata readable, and
advance the HTTP cache format for raw header values.
