Look up the paint graphics stored under attribute for a vector item, in the canonical `List<Graphic>` form.

Iterator over all of the [`Bezier`] following the order that they are stored in the segment domain, skipping invalid segments.

Used when moving layer by the layer panel, does not run any pushing logic. Moves all sole dependents of the layer as well. Ensure that the layer is ab

Construct a [`Bezier`] curve for stroke.

New local/remote op against the working registry: add ops error on duplicate targets and `Change*` ops error on a missing target, while remove ops no-

Get the bottom left corner of the quad.

Wrap an already-materialized snapshot. Trusts `registry` to match `history`; advances the clock past every observed timestamp but does not re-apply op

Update the layer fill to the current gradient

Get the gradient with appearance information from Fill node values, or the chain connected to Fill node / layer.

Minimal set of deltas to transform `from` into `to`. Emits timestamp-less op shapes; the caller (`Document::commit_local` or equivalent) wraps each i

Returns the display name of the node. If the display name is empty, it will return "Untitled Node" or "Untitled Layer" depending on the node type.

Gets the node id of a proto node with a specific reference that is upstream from the layer node, and optionally creates it if it does not exist.

Computes the transform from gradient space to viewport space.

Does the layer have children? If so, then it is a folder.

Open an existing working copy at `path`. Validates the manifest, materializes the session from `registry.bin` (fast path) or by replaying `history.jso

When an event makes the tool change or do something, it is processed here to perform a step (transition) on the tool's finite state machine (FSM). Thi

Builds a `FillChoice::Solid` from a color.

TODO: Remove this when we have proper entry row formatting that includes room for Assists.

Get the bounding box of the click target of the specified layer in viewport space

Check if the user has selected the edge for dragging. Returns which edge in the order: `top, bottom, left, right`

Get whether the subpath is closed.

Stages the runtime network into the `Gdd` working copy.

Creates a new layer and adds it to the document network. network_interface.move_layer_to_stack should be called after

Deselects all segments across every selected layer

Consumes this attribute and returns all values as a Vec of boxed scalar attribute values.

Get the [`TypeSource`] for any InputConnector. If the input is not compiled, then an Unknown or default from the definition is returned.

Drop the session and return the working-copy container + layout. Intended for test code that needs to reopen against the same container; panics if the

Iterate values from `bytes`. Single-value codecs yield exactly one item; stream codecs yield however many were written.

Compose a container path from `basename` and `codec.extension()`.

Get the tilt angle between -180° and 180° in radians.

Commit a single op to a document as a retired delta. Mints a fresh timestamp, links to current head, applies, records in history, advances head.
