How this entity was disambiguated
This entity first appeared as the object of triple T2187941 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

Target entity: HTTP/3 QPACK header compression specification Context triple: [HTTP Working Group, responsibleFor, HTTP/3 QPACK header compression specification]
-
A.
HPACK
HPACK is the dedicated header compression format used by HTTP/2 to efficiently encode and transmit HTTP header fields while maintaining security and performance.
-
B.
HTTP/3
HTTP/3 is the third major version of the Hypertext Transfer Protocol, built on the QUIC transport protocol to provide faster, more reliable, and secure web communication.
-
C.
QUIC
QUIC is a modern, multiplexed transport protocol developed by Google and standardized by the IETF that runs over UDP to provide faster, more secure, and reliable web connections than traditional TCP-based HTTPS.
-
D.
RFC 7540
RFC 7540 is the Internet Engineering Task Force (IETF) standard that defines HTTP/2, the major revision of the Hypertext Transfer Protocol designed to improve web performance and efficiency.
-
E.
QUIC TLS usage specification
The QUIC TLS usage specification is an IETF document that defines how the QUIC transport protocol integrates and uses TLS for secure, encrypted internet communication.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.

How these facts were elicited
The pipeline generated the facts above by prompting gpt-5.1 with this entity's name + description and the instruction below.
Instruction
You are a knowledge base construction expert. Given a subject entity and a description of it, return factual statements that you know for the subject as a JSON list of dictionaries(triples), where keys must be "subject", "predicate" and "object". The number of facts may be very high, between 25 to 50 or more, for very popular subjects. For less popular subjects, the number of facts can be very low, like 5 or 10. # Requirements - If you don't know the subject at all, return an empty list. - If the subject is not a named entity, return an empty list. - Include at least one triple where predicate is "instanceOf". - Do not get too wordy. - Separate several objects into multiple triples with one object.
Input
Subject: HTTP/3 QPACK header compression specification Description of subject: The HTTP/3 QPACK header compression specification defines the mechanism for efficiently compressing HTTP header fields over QUIC while avoiding head-of-line blocking.
