A nullable number as the map value does not survive SDKs that strip null map values or generators that type the value as non-nullable, so an unbounded grant read as off. Presence of the key is now the opt-in and the overdraft limit is an optional member of the value.
SDKs that strip null map values already read {"cred_1": null} as off, so
the engine drops the entry too and a malformed payload fails closed.

credit_postpaid_limit(credit ID to a nullable number) withcredit_postpaid(credit ID to{"overdraft_limit"?: number}). Node, Python and Ruby strip null map values before calling WASM, and typed generators collapse a nullable map value, so an unlimited grant read as off.A credit's presence in the map turns postpaid on, and a missing or null
overdraft_limitmeans no limit. Null always reads as absent: a null map is empty, a null credit entry is dropped (off, as the null-stripping SDKs already read it), and a null limit is no limit.CreditPostpaidMap.UnmarshalJSONdrops the null entries. Evaluation is unchanged. Nothing released reads the old field, so it goes without an alias.schematic-api needs a v0.1.24 tag of this before its matching PR merges.
