"""Single source of truth for where staged actors belong in the DemoMap.
|
|
|
|
This exists because the same value was written in two places and they drifted:
|
|
`ue_hero_facade_import.py` kept the pre-`0.1.0` position `(-12024.5, -1450)` while
|
|
`ue_build_demo_map.py` staged the hero at `(-13336, 1307)`. Running the importer on
|
|
its own therefore moved the hero **13 m east and onto the north side of the
|
|
boulevard** — and nothing complained, because a displaced building still renders.
|
|
|
|
The values are Unreal centimetres, absolute world space. Every one of them is
|
|
verified against `Geo/verification/2026-11-06-el-capitan-block.md` and probed by
|
|
`Tools/visual_loop.py --verify` (via the demo screenshot expectations) and by the
|
|
world-span probes recorded in `MEMORY.md`.
|
|
|
|
Keep this file boring: constants and one validator, no `unreal` import, so it can
|
|
be unit-tested on the host.
