prove clocked relation identity right
Refactor preorder and monotone function code
Error ordering on Delay function type
Move Delay-related files to Semantics
A relational view on our monad (incomplete)
some writing
[abstract semantics] error strictness, ret and ret βη
more progress on semantics: plugging ev ctxts and their equations
update to extensionsystem version of comonads/strong monads
prove substId/substAssoc for EvCtx
ev ctxts all done except for substId/substAssoc and the computation stuff
Begin formalizing coalgebras categorically
Proof that Delay is a final coalgebra
Delay datatype
Move global lift code into separate file
more progress on evaluation contexts, stuck on an upstream issue
most of value semantics, start EvCtx semantics
WIP on term semantics: substitutions and some of values
model of types and precision in an abstract model
make isProp⊑ admissible
A convenient abstract semantics of the term language
a (full?) formulation of a term model
start working on the abstract models. First the term language
Cat of preorders; preorder-enriched cat of preorders
Preorders and monotone functions
Refactoring
some example gtt theorems
Implement the GTT logic, reduce the amount of annotations using nested var generalization
lower the universe level of the terms
finish the term syntax, init the logic
WIP on explicit substitution (much simpler so far)
Some syntax experiments
work on new syntx
Begin porting syntax to GTT and new Context rep
new syntax in progress
Define preorder-enriched cats, refl. graph of preorder enriched cats
Merge branch 'main' of https://gitlab.eecs.umich.edu/gradual-typing/sgdt
changes to wording
work on paper (changes to intro, work on description of syntax)
syntax discussed in today's meeting
