Resolve Invitation Legibility under parameter governance

[Chris-Hibbert]

What is the Problem Being Solved?

Invitation Legibility (AKA "pig in a poke") is about ensuring that invitations (and Invitation patterns) can specify enough detail about contracts to assure a potential acquirer that it does what it says. Parameter governance makes it clear that some aspect of the contract is mutable.

Description of the Design

Create new tools, possibly based on private args to enforce any sensible limits on parameter variation.
To some extent the governing contract is the most plausible place to embed limits on how parameters can be changed. So being able to specify the installation of the governing contract or the governed contract in an invitation pattern would address this some.

This issue is a call for a design discussion.

Security Considerations

Legibility.

Test Plan

TBD when we have a design direction and tasks

[Tartuffo]

Per Mark, moving to 1.1, but this should expand to be parameter legibility all the way to the UI.
