   Thanks for adding these. Two things on `cf33b01a9`:
   
   1. The four delete tests check `table.newScan().planFiles()` with 
`doesNotThrowAnyException()`, but `planFiles()` is lazy. `ManifestGroup.plan()` 
builds the `DeleteFileIndex` right away, but data manifests are only read when 
the iterable is consumed, so the step that matches deletes to data files by 
partition value never runs. The failure we care about here is a delete that 
silently stops applying, which won't throw. Could you iterate the tasks and 
assert on them? For example, filter on `region = 5L` and check the expected 
task count and `task.deletes().size()` (one task with one delete in the 
before/after cases). My earlier probe used that check.
   2. The merge with main brought back `CVE-2026-68494` in 
`.github/trivyignore/kafka-connect-runtime.trivyignore.yaml`. Main dropped that 
entry after the Parquet 1.18.1 bump, so it looks like a leftover from conflict 
resolution. Could you remove it from this PR?
   
   The `ManifestWriter` / `PartitionData` changes look good to me.
