[Feature] Test and Release the Scene Editor

[mudabs]

Description

As the development team, we want repeatable tests for the scene editor so that new editing features do not break existing content or previously completed tools.

Acceptance Criteria

• Core editor workflows have repeatable tests.
• Existing application tests continue to pass.
• Manual rendering and device checks are recorded.
• Known limitations are documented before release.
• The editor is not released until critical acceptance criteria pass.

Test / Verification

• Run automated tests, manual workflows, rendering checks, and device checks before release.

Notes

• Every feature issue should add or update the most relevant verification coverage.
