URL: https://github.com/apache/hudi/pull/19161#issuecomment-5291523827

   Pushed ab6a61c addressing the remaining findings so this can move forward:
   
   - **Restored `TestExportInstantsProcedure` to master.** The branch was still 
reverting the desc-ordering / action-filter / invalid-folder tests from #19172 
(the prod file was restored earlier, but the test file was not), so merging 
would have dropped the regression coverage for the `desc` bug. The PR no longer 
touches export_instants at all.
   - **Fixed the incremental `copy_to_temp_view` test.** The comment had the 
boundary semantics inverted: both bounds are inclusive on *completion* time, 
and passing the last commit's *requested* time as `end_instance_time` excludes 
that commit. The surviving row is the first commit's, and the test now asserts 
`id = 1` instead of a bare count.
   - **Made the filter-evaluator tests pin two real bugs instead of skirting 
them.** Long columns compared against int literals are narrowed to Int, so 
values past Int range silently never match -- pinned with a `3000000000L` row, 
tracked in #19632. Array predicates drop every row because values are never 
wrapped as `ArrayData` -- the tautological `length <=` assertion is now 
explicit `Seq.empty` pins, tracked in #19633.
   - **Documented the `show_logfile_records` workarounds.** The merge test's 
compaction scaffolding and distinct-key updates are required because the merged 
scan crashes on an uncompacted MOR table and on keys updated in more than one 
log block; tracked in #19634 together with the `MatchError` on non-data blocks.
   - **Filed #19635** for two `sync_validate` bugs adjacent to the new coverage 
(catch-up counting hardcodes the commit action, breaking MOR/clustered targets; 
an unguarded `conn.close()` masks JDBC failures with an NPE). No test change 
needed there.
   
   Everything stays test-only; the prod fixes live in the four issues above.
