ADR 0006: Scene Schema Versioning

Status

Accepted

Context

Levels under assets/levels/ need forward-compatible migrations as authoring components evolve (M5).

Decision

  • Track schema_version in scene files (wrapper or sidecar during transition).
  • Provide scene_schema module with migrate_scene_text and validate_level_file.
  • CI / xtask validate-levels loads all committed levels and fails on unknown versions.

Consequences

  • Breaking component changes require a migration step and version bump.
  • Editor save may wrap scenes with schema header in a follow-up change.
