A record so this is not re-derived. The measurement (349 upstream commits since
the 2026-10-12 base, 589 files a full merge conflicts in), why most of it cannot
be cherry-picked (upstream replaced mlua with its own Lua 5.0 VM, and ~200
commits are the deferred-to-inline conversion of the app/VM contract), the two
resolution traps this sync hit, and all 27 refusals with the reason each.
