How this entity was disambiguated
This entity first appeared as the object of triple T2174828 — 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: WritableStreamDefaultController Context triple: [Streams Standard, definesConcept, WritableStreamDefaultController]
-
A.
ReadableStreamDefaultController
ReadableStreamDefaultController is a Web Streams API interface that allows developers to control and manage the internal state, queuing, and data flow of a readable stream.
-
B.
WritableStreamDefaultWriter
WritableStreamDefaultWriter is a JavaScript Streams API interface that provides programmatic control over writing to a writable stream, including queuing, backpressure handling, and closing the stream.
-
C.
WritableStream
WritableStream is a web platform interface representing a destination for streaming data, allowing chunks to be written, queued, and processed asynchronously.
-
D.
TransformStreamDefaultController
TransformStreamDefaultController is a web streams API interface that lets transform stream implementations enqueue, error, or terminate chunks during a streaming transformation.
-
E.
ReadableByteStreamController
ReadableByteStreamController is a Web Streams API interface that manages the internal state and data flow of a readable byte stream, including queuing, backpressure, and pulling data from an underlying source.
- 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: WritableStreamDefaultController Description of subject: WritableStreamDefaultController is a JavaScript Streams API interface that lets you control and manage the internal state, queuing, and backpressure of a writable stream.
