We walked through d4 of rights documents and the associated feedback. The discussion on the changes to fold the rights in with the key block centered on whether this was simpler for everyone. John prefers a separate block structure, even if it is positionally associated with a key block. A concern is that new rules for digest calculation and what other text is allowed interspersed with rights pragmas are necessary with this proposal. A lot of discussion on conditional rights. Dave has done a lot prototyping of alternatives for handling conditional rights and suggested that Synopsys was flexible on the alternatives. John and Ray separatedly expressed concerns about the extent of change implied by structural rights and other content taking a long time to come to consensus on. Steve's written comments were similar. Dave is going to focus on examples illustrating the different mechanisms they have concerned and try to make some comparisons to make his case. We agreed to move the salted key section into interoperability and Ray will take that up.

John walked through his common rights d3 specs and explained what was updated in terms of interaction with tool specific rights and overrides, the areas where changes were made to respond to feedback with better use case descriptions or more clarity on semantics. He suggested that we could drop runtime_visibility value "nonames" and Ray indicated that would be helpful. Others were encouraged to consider doing that and provide feedback. John intends to continue on his work plan with visibility clause.

The work plan was reviewed and updated where possible. See below.
