This document, named CTF2-SPECRC-1.0, is available here: To write CTF2-SPECRC-1.0, many parts of CTF2-PROP-2.0rA [1] were modified to make the text more easily understood and to formalize some procedures. I also added a few diagrams to help understand the binary layout of some fields. Moreover, the metadata stream and auxiliary streams are now JSON text sequences [2] instead of a single JSON array/object. This makes decoding a streamed version of such input easier using any JSON parser, for example to meet the needs of use cases similar to LTTng live [3]. Feel free to provide feedback!
