Reviewed all 17 changed files at head 4471ebb0a93b2cfb6a5d6375058a080e070c800f against the supplied merge-base diff. Two new P2 findings are inline: repeated full partition enumeration when shared caching is unavailable, and retention of obsolete complete partition views after normal table-generation replacement. No P0/P1 finding was verified and no existing inline findings require carrying forward. No additional user focus was supplied.

The review converged after 2 rounds: all three reviewers returned NO_NEW_VALUABLE_FINDINGS in the final round; every candidate and initial risk has an explicit, independently checked disposition. Static review coverage is complete. No builds, tests, benchmarks, source modifications, or submodule initialization were performed. The conclusions below describe inspected code and tests, not runtime validation.

1. Goal and proof: version identity covers table UUID, metadata file, selected snapshot and schema without partition enumeration. Lazy partition views are separately cached. Mock tests inspect identities/selectors and shared loads; the two partition-cache regressions remain.
2. Scope: changes stay within FE Iceberg metadata, SQL-cache integration, and three unit-test files; no unrelated modification found.
3. Concurrency and locks: relation-local snapshots and one physical table-generation lease per statement preserve the binding-to-scan boundary. Existing cache admission/mutation fencing and table locking remain; no additional race, lock-order or deadlock finding verified.
4. Lifecycle and initialization: captured frozen generations/authentication and statement/operation leases preserve resource ownership. The replacement-retention finding concerns redundant full partition maps, not a FileIO leak or stale data. No new static initialization dependency found.
5. Configuration: the new partition entry inherits enable/TTL/capacity/max-weight controls and generic catalog reset handling. Disabled/rejected admission triggers the repeated-work finding.
6. Compatibility: changes affect in-memory FE identities and cache keys; no persistent storage layout or backend function-symbol change.
7. Thrift/protobuf: none changed, so release-branch field/enum comparison is not applicable.
8. Parallel paths: native Iceberg, ordinary Hive, OLAP, mixed external scans, HMS-backed Iceberg and system-table exclusions were traced. Unsupported/versionless providers bypass caching; no additional issue verified.
9. Special conditions: immutable original selectors, branch/tag restrictions, explicit snapshots, missing identities and empty-table sentinels were inspected through their actual resolvers. No additional stale-hit path found.
10. Test coverage: added tests cover identity dimensions, defensive selector copies, independent references, sharing and explicit invalidation. Disabled/rejected multi-partition refresh and normal generation replacement are not covered; end-to-end cache hit/miss behavior was inspected only.
11. Expected results: no regression result files changed; new unit-test assertions match their mocked paths but do not exercise the two findings.
12. Observability: the new entry inherits cache load/admission statistics, and existing exception/logging boundaries remain; no extra observability defect verified.
13. Transactions and persistence: no EditLog, replay, commit, visibility publication or failover path changed.
14. Data writes and crashes: no data-write path changed. The writable projection's rewrite-task consumer does not access lazy partition information after commit; existing cleanup ownership was traced.
15. FE/BE variables: no new transmitted variable; existing SQL-key/cache parameter messages are reused.
16. Performance and memory: version extraction avoids partition reads, and partition payloads have a separate estimator. The two inline findings identify repeated enumeration and avoidable obsolete-generation retention; neither alleges an unbounded leak or measured runtime impact.
17. Remaining/core invariants: no new BE memory/null/Status path, MoW delete bitmap, or internal data-version write semantics are touched. Provider/cache failures disable caching. Immutable-map consumers read or copy their inputs. No unresolved code-level question or unreviewed changed scope remains.

Review converged after 2 round(s).

Static review of PR 69983 completed at head 350e47d. The review converged after 2 bounded rounds. The changed SQL-cache/MVCC selector flow, Iceberg generation retirement and accounting, bulk native/HMS MTMV snapshot flow, and Iceberg cache admission were traced end to end. One P1 finding is included below: lazy partition/schema loading can fail for retained projections after an Iceberg catalog reset retires the cache group, even though the retained table generation is still expected to serve pinned work. Existing P2 comments 4442498716 and 4442499089 were independently revalidated as fixed on this head and are not reposted. The supplied review focus has no additional points. Tests and builds were not run because this invocation is static-only; changed tests were inspected as review evidence.

Review converged after 2 rounds at the verified head 1385a1e. I found one new P2 performance regression: the lazy Iceberg partition supplier is not memoized for unadmitted/direct projections, so dictionary freshness checks can rerun PartitionsTable.planFiles() and rebuild the full partition maps on every check. The earlier MTMV bulk-refresh finding (comment 4442499089) was independently confirmed fixed and is a distinct consumer; the reset-safe partition finding (comment 4446153215) was also confirmed fixed. The SQL-cache/MVCC selector and cache-generation review found no additional issue. The supplied review focus file contains no extra focus points. This was a static review only; no builds or tests were run.

Automated static review of PR 69983 at head f80fa3b, completed in two bounded rounds and converged.

The review covers the new selector-aware Iceberg SQL-cache dependencies, pinned latest/VERSION/TIME/branch/tag identities, CacheAnalyzer admission, native and HMS Iceberg MV bulk snapshot loading, lazy partition-entry admission and retirement, catalog reset and generation fencing, immutable partition maps, and cache accounting. The SQL-cache and MVCC paths preserve selector and generation identity; provider-absent HMS/system-table variants fail closed. The prior inline threads about partition-view reuse, reset-safe loading, generation retirement, and dictionary freshness were revalidated at this head and are fixed, so they are not reposted. No additional user-provided focus was supplied.

Critical checkpoints: the change is focused on cache/version and partition-metadata lifecycle behavior; external metadata is paired with retained generations and captured authenticators; reset/replacement fences and admission checks were rechecked; no protocol, persistence, write-transaction, or new configuration changes were introduced; native and HMS parallel paths were reviewed. Added tests were inspected but not executed, and no builds or runtime tests were run because this invocation is static-only.

One P2 issue is reported inline: the retained-table lazy partition loader now constructs the schema directly and bypasses the existing SchemaCacheValue.validateSchema() boundary, so case-insensitive duplicate Iceberg columns can enter MV/dictionary partition range or snapshot derivation even though normal schema access rejects them. Restore validation while preserving the reset-safe retained-table path.

Review converged after 2 round(s).

Reviewed the complete PR diff at the pinned head, including the new Iceberg lazy partition cache, native Iceberg SQL-cache versioning and MVCC selector keys, HMS Iceberg MTMV bulk dispatch, schema derivation, cache accounting, generation retirement, and all changed tests. The implementation keeps partition metadata bound to the retained table generation and authenticator, fences cache publication across replacement/reset races, validates retained schemas, and preserves the existing table-snapshot fallback and per-partition AnalysisException recording. Native Iceberg SQL-cache identities cover the physical table generation, selected snapshot and schema; HMS-backed Iceberg scans remain safely uncacheable as they were before this PR because they do not implement the provider used by the new analyzer path.

All five existing inline threads were independently rechecked at head 5d3cb75: the repeated partition-load, generation-retirement, retained-projection reset, dictionary scalar, and retained-schema-validation concerns are addressed by the current code and must not be reposted. No new verified finding remains, so there are no inline comments or still-applicable blocking comment IDs.

The review converged in round 1. This was a static-only review: the added tests and relevant call paths were inspected, but no builds or tests were executed.
