dvs

note: this is a "develop-in-the-open" active rewrite targetting stabilization in ~March 2026, for the moment expect major breakage/instability as we

consolidate the feature set we want to support in dvs for this next release.

please contact us if these ideas or discussion points are of interest, we'd love to get more collaborative discussions going
