## Proposed changes - Enable the Paimon JDBC catalog lock in the existing object-storage fixture so concurrent snapshot commits use a supported configuration. - Add synchronized two-session write coverage for append tables across different and identical partitions, fixed-bucket deduplication, aggregation lost-update detection, and dynamic buckets with disjoint partitions. - Add write-to-read closure coverage for snapshots, tags, and branches created from Doris commits. - Keep the unsupported Paimon branch sink boundary explicit and verify rejected INSERT and INSERT OVERWRITE statements do not mutate main, tag, branch, or historical snapshot state. ## Motivation The existing P0 suites cover broad serial write behavior, table models, merge engines, scalar and nested types, schema evolution, transactions, and failure paths. They did not exercise independent Doris transactions committing concurrently to one Paimon table, or verify time travel and references rooted in snapshots written by Doris. ## Validation - test_paimon_jdbc_catalog: PASS with Paimon 1.3.1, JDBC catalog locking, and object storage - test_paimon_write_snapshot_refs: PASS with cross-engine Spark and Doris result comparison - git diff --check: PASS -- This is an automated message from the Apache Git Service.
