Detailed Description

The shipped set plus one user's own drawings.

Uploads and pulls live in ``<user dir>/layerx/drawings`` as ``<id>.json`` with
a ``<id>.meta.json`` beside them. Shipped drawings are read in place and
never copied.

_feedtwin_library()

List[Drawing] engine.layerx.sources.DrawingStore._feedtwin_library ( self )

protected

The drawings in the feed twin's library, read in place: Layer X burns the feed system
the twin holds (2026-10-03, "pull from it and trust it"), including what the twin pulled
from pid-designer, not only the files feed-twin ships.

_sample()

List[Drawing] engine.layerx.sources.DrawingStore._sample ( self )

protected

The drawings in feed-twin's sample set, read in place: featured. A library that already
holds the same bytes lists it under the library's name (``list`` keeps the first met).

add()

Drawing engine.layerx.sources.DrawingStore.add	(		self,
		Mapping[str, Any]	payload,
		*	,
		str	name,
		str	source )

Store a drawing. Same bytes, same id: adding twice is a no-op that
updates nothing but the name a person sees.
