Summary

Ports the 5-phase investigation plan and agent handoff prompt for replacing the current SceneCapture2D-based editor preview with a native FDisplayXRDevice → PIE hookup.

These docs previously lived only on the predecessor repo's editor-preview-xr-native branch. Without them here, any agent told to pick up the native-preview work has no primary source material. With them, the task is self-contained in this repo.

Cross-references to the deleted Docs/Internal/ handoff docs and to the predecessor LeiaUnrealSDK repo/paths have been removed; the load-bearing historical claims (e.g. "PIE does not call `UpdateViewport`") are inlined.

Files

  • Added `Docs/DisplayXR/EditorPreviewNative.md` — 5-phase plan (context, why it failed before, goal, investigation phases 1–5, risks, out-of-scope, critical files, verification)
  • Added `Docs/DisplayXR/EditorPreviewNative-AgentPrompt.md` — ready-to-paste prompt for kicking off Phase 1
  • Modified `Docs/DisplayXR/README.md` — index entries for the two new docs
  • Modified `Docs/DisplayXR/TODO.md` — link to plan, drop the "not yet merged" note

Test plan

  • `lint.yml` passes all three checks
  • Manual: links in new docs resolve within this repo
  • Manual: agent prompt reads as a self-contained handoff without predecessor-repo context

The 5-phase investigation plan and agent handoff prompt for replacing
the current SceneCapture-based editor preview with a native
FDisplayXRDevice → PIE hookup. Ported from the predecessor branch;
Docs/Internal/ and LeiaUnrealSDK cross-references removed.

Adds:
- Docs/DisplayXR/EditorPreviewNative.md (5-phase plan)
- Docs/DisplayXR/EditorPreviewNative-AgentPrompt.md (agent handoff)

Updates:
- Docs/DisplayXR/README.md index
- Docs/DisplayXR/TODO.md (link to plan, drop "not yet merged" note)
