Summary

Investigate spawning the game as a separate process and syncing selected state back to the editor.

Why

Out-of-process preview can improve isolation but adds synchronization, process control, and debugging complexity.

Implementation notes

Prototype process launch, health check, and shutdown.
Sync a narrow selected-state or transform subset only.
Compare against current in-process PIE and BRP prototype results.
Document costs before making architecture changes.

Acceptance criteria

Spike demonstrates or rejects minimal process launch/sync flow.
Risks and UX tradeoffs are documented.
No existing in-process PIE behavior regresses.
Follow-up architecture decision is captured if continuing.

Tests/docs

Spike notes and smoke script if retained. Update ADR only if direction becomes durable.
