…snapshot; Doris #67306 conflicts resolved ArcadeDB's maintainer implemented COPY ... TO STDOUT (text, csv, binary, both protocol paths) in #7398, merged 2026-09-10 and in 26.10.1-SNAPSHOT. Verified the same day: the stream is correct on the wire and rows match the Describe OIDs, but the Arrow driver's default path still stops at row 0 because the binary header is framed as its own CopyData message where PostgreSQL bundles it with the first row; use_copy=false still passes 7/7. Doris #67306: conflicts resolved at a maintainer's request on 2026-09-11.

26.10.1-SNAPSHOT). Verified on the snapshot: COPY is correct on the wire (psql, libpq; rows matchDescribeOIDs byte for byte), but the Arrow driver's default path still stops at row 0 because ArcadeDB frames the binary header as its ownCopyDatamessage while PostgreSQL bundles it with the first row, which the driver's reader relies on.use_copy=falsestill passes all seven probe steps. Raw runs inprivate/native-probe/results-2026-09-10-arcadedb-snapshot-7398*.jsonl.Docs only. Both ArcadeDB notes are updated in the site source and go out with the next gh-pages push.
