//! `wai.media.contribution` (extensions/contribution.md): the committed corpus
|
|
//! `live-conformance/contribution/` regenerates byte for byte from its fixed seeds, holds no
|
|
//! other file, every case in it gets the outcome it states, and the extension's §11 lists
|
|
//! exactly the reasons the reference reports. The generator itself asserts that the corpus
|
|
//! gives every one of them.
