After a few requests and clearing with all the original commenters, I’m happy to share the original design doc for anyone that’s interested, including discussions. This was great and the open source community at its best.
The published google doc is below (which doesn’t allow including read-only comments unfortunately).
Metro (née Lattice) Design Doc
For a version with comments, I’ve published an exported html dump to the metro doc site here: https://zacsweers.github.io/metro/0.8.0-SNAPSHOT/designdoc.html. Comments are annotated footnotes.
After the next release, that link will have a more permanent home here: https://zacsweers.github.io/metro/latest/designdoc.html
