Is there a way to see the parts of context receivers that are currently available? The closest thing to docs i know of is the KEEP which is more of a proposal than up to date docs. the main difference im seeing is not having the context(...){ } scoping function to provide multiple values to the implicit context for calling functions with context params. Is this planned for a future release or has the implementation and plans just diverged from the original KEEP?

Those functions should eventually be added to stdlib, but in the meantime you can define them yourself:

inline fun <A, B, R> context(a: A, b: B, block: context(A, B) () -> R {
  contract {
    callsInPlace(block, EXACTLY_ONCE)
  }
  return block(a, b)
}

And implicit is provided in that KEEP as such:

context(ctx: A) fun <A> implicit(): A = ctx
