"""Load authored world content and cross-check origin references.

|
Language-neutral content integrity: every id an origin references (start
|
|
location, start quest, granted items, seeded npc dispositions) must resolve in
|
|
world content. New-game construction (client-side, Plan B) relies on this
|
|
holding; catching it here fails a broken origin at authoring time, not three
|
|
scenes into play.
