0.8.0 (2026-10-25)

Bug Fixes

• agents: the script inbox is no longer dropped with the stack frame (43b66f2)
• assets: a material's textures load with it (21805ef)
• control: gameplay time no longer follows the physics strategy (86ee883)
• correctness pass — ECS undefined behavior, Ergon silent wrongs, script persistence holes (f01ec86)
• data: a marker component belongs in the scene that declared it (84a6046)
• data: a placed entity always has a world pose (5ffa39a)
• ecs: compaction repoints by row, not by identity (e7b38a7)

• layout: the mesh module and the lanes' test helpers follow the file conventions (95be658)
• macros: a tuple component with a skipped field derives (4ce453f)
