Carry the wire reason phrase through buffered and streaming transport,
response conversion, cache, and Window/Worker Fetch and XHR delivery.
Preserve explicitly empty messages, including HTTP/2 and HTTP/3, and
Latin-1 reason bytes while retaining existing synthetic defaults.
Bump cache metadata to version 4 and keep the original status message
when revalidating an entity with a 304 response. Cover transport modes,
cache reloads, response conversions, and streaming XHR state changes.
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.
Validation:
- cargo fmt --all
- cargo clippy --workspace --all-targets --all-features -- -D warnings
- cargo nextest run --no-fail-fast
