Anchor

The placement mode of a world object, determining whether it belongs to the personal carry layer or the shared field layer.

Values:

• carry — the object travels with the member (also: user anchored)
• field — the object is fixed in the shared spatial panorama (also: world anchored)
• object — the object is anchored to another object in the field; moves with that object rather than the member or the fixed environment (future; XR-relevant)

Allowed:

• anchor mode
• anchor_mode (API field name)
• carry anchor
• field anchor

Forbidden:

• placement mode (acceptable in technical docs prose; not the canonical noun)
• attachment type
• position type
• slot

Notes:

• anchor_mode is the canonical API field name. Use it in code and payloads.
• Do not expose "anchor" as a product-facing noun in UI copy. In UI, the distinction is surfaced as the carry layer vs. the field.
