classpath"
+# The Gluten bundle jar must be on the spark project's TEST runtime classpath
+# (so DeltaSQLCommandTest can load org.apache.gluten.GlutenPlugin by name) but
+# NOT on the COMPILE classpath of `sparkV1`, which is the project that holds
+# Delta's main sources. The bundle's transitive contents include extra symbols
+# under `org.apache.spark.sql` that collide with Delta's main sources -- e.g.
+# MergeOutputGeneration.scala imports both `org.apache.spark.sql._` and
+# `org.apache.spark.sql.delta.ClassicColumnConversions._`, and would then fail
+# with `reference to expression is ambiguous`.
+#
+# sbt auto-scans `<baseDirectory>/lib` via `unmanagedBase`. Two relevant
+# projects in Delta v4.2.0 have a `lib/` baseDirectory:
+#   - sparkV1: `project in file("spark")`     -> spark/lib
+#   - spark  : `project in file("spark-unified")` -> spark-unified/lib
+# unmanagedJars are project-scoped (NOT inherited by dependents), so dropping
+# the bundle into spark-unified/lib/ adds it to the unified `spark` project's
+# Compile *and* Test classpaths -- but NOT to sparkV1's. That's exactly what
+# we want:
+#   * sparkV1/Compile sees ONLY Delta's regular deps -> Delta main compiles.
+#   * spark/Test/fullClasspath sees the bundle -> tests load GlutenPlugin.
+# (Verified empirically: with bundle only in spark-unified/lib/, sbt's
+#  `show sparkV1/Compile/dependencyClasspath` excludes the bundle and
+#  `show spark/Test/fullClasspath` includes it.)
+#
+# We deliberately do NOT also drop the bundle into spark/lib/, which is what
+# caused the previous compile failure: spark/lib/ is sparkV1's unmanagedBase,
+# and putting the bundle there would re-introduce the ambiguity errors.

Review Comment:
   Reasonable point - matching an exact XML tag string is brittle if Delta 
reformats it. Worth considering a more robust regex, but since the workflow 
pins specific delta_ref values, the risk is low in practice. Could improve 
later.
