Plan A of two: the JSON Schema contract, authored POC fixtures (deserter
origin + minimal world), and the api's runtime validation of every canon log
(422 on invalid, enforcing the §7 luck boundary). Five TDD tasks, all runnable
with pytest + Docker in-repo. Plan B (GDScript client construction/maintenance)
deferred until we're in Godot.
