Chunks keep the player's bytes apart from the composed density: plan
presses land in an owner-keyed PlanTerrainPatch that is retracted with
its feature and never touches history, so removing a railway takes its
bed with it and a human fill under it survives. Surface queries answer
Surface | Hole | Outside instead of pretending the heightfield continues
over a hole or past the border; landforms issued inside a plan eval are
plan, outside it history. Seven tests pin the layering, including
same-inputs-twice equality.

Squashed from work; the fine-grained history is under tag archive/work-2026-08-29:
- mp* wave: mpwm window manager + the mp app family, WM API, theme bridge, PDF engine fix
- mpwm polish wave: terminal key focus, focus-history close order, pop-back-to-origin, occupied-workspace cycling, demo
- work: land the sources the last commits reference
- route: the assistant icon the committed UI references
- fast_inflate: the benches name their dev-deps
- gif/weezl: drop the vendored benches nobody can run
- weezl: the decode tests generate their own LZW fixture
Drop the archived old/ tree, root AI notes, splashgame.md (Arcade lives
in the private sandbox), widgets-dll leftovers, and LAN/oracle helper
scripts. Move download_*.sh into tools/, and move sim/math out of
libs/game/ so the public repo no longer has a game/ directory.
Also quiet first-party compile noise and skip asset-ui tests that need
sandbox kits or uncommitted fixtures.
