  "message": "Reduce repeated work in HTTP header parsing (#13376)\n\nReduce repeated work in HTTP header parsing.\n\n1. Replace per-byte libc calls in URL compliance validation with a vectorizable, locale-independent ASCII range check.\n2. Simplify request-target validation using the stored URL fields.\n3. Combine field-name colon scanning, hashing, and character validation into one pass, reusing the existing well-known-string table.\n4. Skip duplicate lookup for well-known fields when their presence bit is clear.\n5. Append adjacent duplicate fields in constant time instead of searching the duplicate chain.\n\nIncludes a header parsing benchmark harness and regression tests for validation, field-name scanning, duplicate attachment, and parser reuse.",
