Re-review follow-up at `494d5201639`: - Preserved historical last-wins behavior for exactly repeated serialized names while applying `mapKeyDedupPolicy` to collisions introduced by CHAR/VARCHAR normalization in both JSON and XML. Added CHAR and VARCHAR coverage under EXCEPTION and LAST_WIN. - Expanded `spark.sql.mapKeyDedupPolicy` documentation to cover `from_json` and `from_xml`, constrained and non-binary-collated keys, both policies, and historical UTF8_BINARY STRING behavior. - Centralized terminal duplicate-key cause classification across parser recovery boundaries. - Added CHAR input coverage for `schema_of_json`, `schema_of_csv`, and `schema_of_xml`. Focused tests: `sql/testOnly *CharVarcharTestSuite -- -z SPARK-59274` (3 passed). -- This is an automated message from the Apache Git Service.
