+ * - `MetadataLogFileIndex` lives at `org.apache.spark.sql.execution.streaming.*` (4.1 moved it to

+ * - `FileStreamSink` likewise lives at `...execution.streaming.*` (4.1 moved it to `.sinks`).
+ * - `UnresolvedWith.cteRelations` is `Seq[(String, SubqueryAlias)]` — 4.1 extended the tuple with
+ * a trailing `Option[Int]` depth.
+ *
+ * Runtime dispatch picks this class over the 4.1 `Spark4Shim` because paimon-spark-4.0's own
+ * `target/classes` is ahead of the shaded paimon-spark4-common copy on the classpath. The
+ * `SparkShim` SPI file registered in paimon-spark4-common points at
+ * `org.apache.spark.sql.paimon.shims.Spark4Shim`; classloader resolution returns this 4.0 class.

+/**
+ * Test-scope stubs for Spark 4.1-only `StreamTest` inner classes.
+ *
+ * Spark 4.1 added several `CheckAnswer` / `WaitUntil` helpers inside `StreamTest`; Paimon's shared
+ * test base classes in `paimon-spark-ut` mix in `StreamTest` and are compiled against Spark 4.1.1
+ * (the default `spark.version` under the `spark4` profile), so their compiled bytecode has
+ * constant-pool references to the nested companion objects.
+ *
+ * When those test classes are loaded on a Spark 4.0.2 runtime (the paimon-spark-4.0 test suite),
+ * `junit-vintage`'s discovery phase tries to verify each class and fails to link the missing 4.1
+ * symbols, crashing the engine before any Paimon test can run. No Paimon test actually invokes
+ * these helpers — the references only exist in the constant pool from trait-mix-in synthetic
+ * forwarders — so empty class files with the matching names are enough to satisfy the verifier.
+ *
+ * Diffing `spark-sql_2.13-4.1.1-tests.jar` against `spark-sql_2.13-4.0.1-tests.jar` shows the
+ * following `StreamTest$…` classes are 4.1-only:
+ *
+ * companion objects (always referenced via MODULE$ access):
+ * - `StreamTest$CheckAnswerWithTimeout$`
+ * - `StreamTest$CheckAnswerRowsContainsWithTimeout$`
+ * - `StreamTest$CheckAnswerRowsNoWait$`
+ * - `StreamTest$WaitUntilBatchProcessed$`
+ * - `StreamTest$WaitUntilCurrentBatchProcessed$`
+ *
+ * case classes (may be referenced as parameter / return types):
+ * - `StreamTest$CheckAnswerRowsContainsWithTimeout`
+ * - `StreamTest$CheckAnswerRowsNoWait`
+ * - `StreamTest$WaitUntilBatchProcessed`
+ *
+ * Scala's backtick syntax lets us declare classes whose compiled names contain `$`, so each stub
+ * compiles to exactly the file name expected by the verifier. They live in `src/test/scala/` so
+ * they are never packaged into any production jar (including the paimon-spark-4.0 shaded artifact)
+ * and do not leak onto Spark 4.1 classpaths where the real symbols must win.

+/**
+ * Spark 4.1-only Resolution-batch rule that rewrites UPDATE plans targeting pure append-only Paimon
+ * tables (no PK / RT / DE / DV) into the V2 `ReplaceData` plan — the same form Spark's built-in
+ * `RewriteUpdateTable` produces for `SupportsRowLevelOperations` tables.
+ *
+ * Why this rule exists: Spark 4.1 moved `RewriteUpdateTable` into the main Resolution batch AND
+ * implemented its `apply` with `plan resolveOperators { ... }`. `AnalysisHelper.resolveOperators*`
+ * short-circuits on already-`analyzed` plans, so by the time the rewrite would run the append-only
+ * `UpdateTable` node has transitioned to `analyzed=true` and the rewrite silently skips. The
+ * `UpdateTable` then falls through to the physical planner which rejects it with
+ * `UNSUPPORTED_FEATURE.TABLE_OPERATION`.
+ *
+ * Firing this rule in the Resolution batch via `transformDown` guarded by
+ * `AnalysisHelper.allowInvokingTransformsInAnalyzer` intercepts the plan before the analyzed flag
+ * traps Spark's own rule. The body is a near-verbatim transcription of
+ * `RewriteUpdateTable.buildReplaceDataPlan` / `buildReplaceDataWithUnionPlan` so the result goes
+ * through Paimon's V2 row-level write path (`PaimonSparkCopyOnWriteOperation` ->
+ * `PaimonV2WriteBuilder` -> `PaimonBatchWrite`) exactly like Spark would have produced. The class
+ * lives in `org.apache.spark.sql.catalyst.analysis` so it can reference the package-private
+ * `RowLevelOperationTable` / `ReplaceData` types and the protected helpers on
+ * `RewriteRowLevelCommand`.
+ *
+ * One subtlety: Spark's `RewriteUpdateTable` guards on `u.aligned`, which is set by its
+ * `ResolveAssignments` rule running earlier in the Resolution batch. Because we fire before that
+ * alignment has taken effect, `u.aligned` is always `false` for us. The rule therefore mixes in
+ * Paimon's `AssignmentAlignmentHelper` and aligns assignments itself before invoking
+ * `buildReplaceDataPlan`, which expects one assignment per target data column.
+ *
+ * The scope is intentionally narrow:
+ * - `SPARK_VERSION >= "4.1"` — earlier versions don't exhibit the short-circuit
+ * - pure append-only `FileStoreTable`s (no PK / RT / DE / DV) — Spark 4.1 can't rewrite them
+ * - no CHAR columns — Spark's `CharVarcharCodegenUtils.readSidePadding` Project races with this
+ * rewrite and trips CheckAnalysis if we intercept before the padding stabilises; those plans
+ * fall through to Paimon's postHoc `PaimonUpdateTable` V1 fallback instead
+ *
+ * Tables with row-tracking / data-evolution / deletion-vectors still route through Spark's V2 path
+ * (which handles them correctly). Primary-key tables fall under Paimon's existing postHoc rule.
+ * MERGE is not handled here — postHoc `PaimonMergeInto` covers it.
+ *
+ * DELETE handling (secondary responsibility): Spark 4.1's `RewriteDeleteFromTable` successfully
+ * rewrites append-only DELETE into a V2 `ReplaceData` plan, which is semantically correct but
+ * defeats Paimon's metadata-only-delete optimization (`OptimizeMetadataOnlyDeleteFromPaimonTable`
+ * converts a partition-only predicate DELETE into a fast `TruncatePaimonTableWithFilter`). Spark's
