Began first discussion (led by Simon Peeters) for physics performance goals for PD II.  Discussed various triggering studies and requirements, from simplest minimal triggers (already existing) to more sophisticated ones, including APA/CPA crossing cosmics, or Michel triggers.

Had first timing-diagram level discussion of trigger arbitration that will be done in MLT.  It is clear that coincidences between TCs that have very different timestamps but are nonetheless associated with the same detector physics, will need to be handled easily, and that merging of triggers will also require some reasonably thoughtful algorithm, but will be based on time, not location.

Updates to Specification Document have begun.  Need to have gitlab versions pushed so that we can see it all on Overleaf so as not to make redundant edits/changes.
