CI sandbox on grokspice's fork, not for merging. This branch applies the final regression tests of #1's branch to the unchanged spiceai-55 base, so the Tests job records them failing before the fix. The real PR goes to spiceai/datafusion-table-providers.

Converted to draft — this sandbox has produced the evidence it was opened for.

It is the red half of the pair for the upsert fix under review in spiceai#89. Run 37894009849, Tests job, on the regression tests alone against the unchanged spiceai-55 base:

test result: FAILED. 483 passed; 9 failed; 2 ignored; 0 measured; 0 filtered out; finished in 67.78s

All nine failures are the new cases, each showing the last copy of a repeated key being lost:

duckdb::write::test::upsert_overwrite_keeps_the_last_copy_of_a_key_repeated_across_batches
  left: (8192, Some("first"))   right: (8192, Some("last"))
duckdb::write::test::upsert_keeps_the_last_copy_of_a_key_repeated_within_a_batch
  left: (3, Some("first"))      right: (3, Some("last"))
duckdb::write::test::upsert_overwrite_keeps_the_last_of_many_copies_under_a_parallel_scan
  left: (51, Some("copy 5"))    right: (51, Some("copy 49"))

The green half is #1 at head ecf886a0, run 37917555233: Tests → ok. 519 passed; 0 failed; 2 ignored.

Draft rather than closed so the links from #89 keep resolving to a live PR. Not for merging.

This sandbox is obsolete: the fix it gathered evidence for, spiceai#89, merged on 2026-10-18 as 87c2cba. Nothing here is meant to merge, and it still counts as one of grokspice's open code PRs. A person can close it; bots don't close PRs to make room under the cap.
