### Purpose - Freeze the FM V1 checksum contract as IEEE CRC32 over stored bytes plus the compression ID. - Make exact verification values an optional, feature-flagged sidecar while safely declining dense index evaluation when it is absent. - Avoid repeated physical reads with zero or undersized caches, including block-wise null bitmap scans. - Cross-check container and partition feature flags and add regression coverage. ### Tests - mvn -pl paimon-common -DwildcardSuites=none -Dtest=FMGlobalIndexTest,FMIndexSuffixArrayTest test - 28 tests passed; checkstyle, spotless, and enforcer passed. -- This is an automated message from the Apache Git Service.
