Interface IngestCtx

Clipboard-paste seam — present when the hosting SceneCanvas supplied an adapter with commitPaste. reviver comes from SceneCanvasProps.ingestion.clipboard. Absent ⇒ the kit weasel-JSON handler declines inert (dwarn, nothing ingested) — its matched items were already consumed at match time, so they do NOT fall through; only match-level misses flow on to other handlers.

Set to true by the kit weasel-JSON handler when it successfully pastes a payload in this event. The ctx object is shared across all handlers in one runIngest call, and higher-priority handlers' handle bodies run (synchronously) before lower ones — so kit:svg's text/plain SVG fallback reads this to decline the SVG flavor of a copy whose canonical weasel-JSON flavor already ingested (avoids a double-paste when both flavors ride one clipboard event).

Full action-deps bag, for consumer handlers that need more.

The kit insert dep — id/layer/undoable-op supplied; the canonical way for a handler to mint a node (insert.commit(bounds, { kind, ... })).

World-space arrival point (drop / pointed imperative ingest); null for paste and point-less calls — handlers pick their own policy (the kit image handler centers on the viewport).

Consumer file→src resolver (SceneCanvas ingestion.resolveSrc). When absent, the kit image handler embeds as a data: URI.

Kit SVG-handler options (SceneCanvas ingestion.svg) — e.g. { unpack: unpackSvgFiles } (from @weasel-js/svg) to parse SVG files into scene nodes.
