Soul F5. F7 (operator, 2026-09-30): "Schema aliasing sounds like a really
bad idea, I support retiring it." CultNetDocumentRegistry.Register wrote
both maps unconditionally, so the last binding for a schema id won.
- Register refuses a binding whose type already holds another schema id,
or whose schema id another type holds, with the reference runtime's
CultSchemaConflictException: the new binding's schema id, both document
types, an empty record key. Nothing is bound on refusal. Binding a type
to the schema id it holds again replaces the binding. This matches Rust
(fc3f3ee5) and Kotlin.
- Tests: both claimant shapes in both orders with two bindings ahead of
the holder (F6/M11), the first binding intact afterwards, and a same-type
rebind replacing.
