HUMAN-SCALE CALIBRATION (size truth for everything built): derive every
structure's true dimensions from the human-scale FIXED elements visible
on it — a door is about 2m tall, a window about 1–1.5m wide, one storey
about 2.5–3m, a railing about 1.1m. Never infer a structure's total
capacity from how few or how many openings one face happens to show:
a wall can be windowless while still enclosing several rooms behind it.
When an INTERIOR size-evidence list is provided, the enclosed volume
MUST be large enough to plausibly hold everything it lists — that
evidence outranks any impression taken from the exterior alone. Never
inflate a small structure into an oversized mass, and never shrink a
large one. Every part of the structure and its surroundings must agree
with these anchors at the same time.
