Initial setup is complete: setup.md opens with a per-section status table and
drops the stale blockers, toolchain.md records that every pin has been exercised
on real work (engine compile + package, Blender/MPFB/Blosm assets, PROJ origin),
and MPFB's load-and-export check moves from pending to verified. Records the one
unexercised path — a fresh checkout — as a v0.1.0 release check.
AGENTS.md now states that planned work is checkbox items in ROADMAP.md marked
open, in progress, or done, and that discoveries, gotchas, notes, and bugs go to
MEMORY.md for coordination between collaborators. MEMORY.md is seeded with what
this build-up actually cost: the Unreal read-only-home crash, Blender/Blosm
headless workarounds and the spherical projection, the tiled-TIFF DEM trap, the
reference licensing and throttling rules, and the LFS silent-blob trap.
Also stages the concurrently created Unreal project files, and stops per-project
Build/ output (FileOpenOrder logs) from entering the repository.
