without the proof for canonical subtyping yet.
starting a bit on a Candid formalization, focusing on the Opt-to-constituent rule. Stuck at #146, and worked around by adding restrictions to the compositional rule for opt.
only to `NoOpportunisticDecoding` so far. Dealing with data structures (even simple ones like lists) in Coq can be a pain, and the ugilness of these proves have greatly increased, so keeping this on a branch for now. Maybe I’ll find the right sweet spot later.

…ence (#171) A revamp of the Coq development: * It models the subtype-checking on decoding (#168). Looks good * It connects MiniCandid to the IDL-Soundness theorem. The main work here is the subtyping-compositonality lemma. ``` If t1 <: t2 and s1 in t1 <: s2 in t2 then s1 <: s2. ``` With this in place, instantiating the “canonical subtyping” proof there works nicely. * It proves transitive coherence with regard to the relaxed relation as per #173 * Mild coqdoc’ifiacation. I’d like to eventually render these to HTML and host them somewhere. It’s very annoying that Github Action artifacts, even if they are HTML, are not directly accessible with the browser. Maybe setup Github pages? It is still a Mini-Candid with a limited set of types, but I think it has all the interesting ones to cover the corner cases. Even adding vectors adds a lot of technical noise with little additional insight (see #154.)
