SDK

Extension, contribution and editor-session APIs for Volter Editor. This package depends on the project contracts, not the editor implementation or game runtime.

The viewport presentation contract accepts a root identity and native mounted adapter surface. It does not require a game's input system, loop or execution API. Richer product-owned roots can satisfy that interface directly.

Account/generation projections, project-tool declarations and tab observations used by this SDK live here, transferred from the former general SDK. They are data contracts, not provider integrations. The rest of that old SDK is not included by default. Editor appearance data types have one owner in the project contract and are exposed through the SDK's contribution-facing entry points.

Capture scope is explicit. captureEditorChrome({region: 'page'}) reconstructs the editor page, including chat and panels, from its DOM and canvas surfaces. region: 'document' limits that reconstruction to the active document, including its visible overlays. region: 'play' captures the active document's visible Play frame, including its React HUD, and refuses when no such frame is mounted. These reconstruct the editor's rendered surfaces, rather than using CDP, browser chrome or a desktop image. EditorClient.captureGame() captures the running game stack, including its React HUD when the game bridge supports the composite; callers must inspect composite and report a canvas-only fallback. Model Play fits its frame to the project's declared resolution; captureEditorChrome({region: 'play'}) captures that frame without the authoring navigation or readouts. region: 'document' includes the surrounding document as well. captureActiveDocument() captures the viewport drawing without its navigation/readouts or DOM HUD. It can still contain in-scene references and notes; it is not a final Blender render. Use an actual bpy.ops.render.render() when verifying Blender output visibility. A raw canvas recording excludes DOM UI. Use editor captures to inspect authoring and game captures to judge the game; measure capture cost separately from gameplay observed without capture.

Run npm run typecheck -w @volter/sdk through the active World. This package is private during migration. Existing session wire names remain intact until their host and Code-OSS consumers move together; package renaming alone does not complete product branding or consumer cutover.
