       every row of a padded batch, so translation runs one sentence per call
       (~4× slower than batch 8 would be). Re-check after the 4.3 upgrade with
       `bun scripts/bench-translate.ts` ("output identical" across batch sizes).
+      **Re-checked on 4.3.2 (2026-10-30): still broken** — a batch of 4 Danish
+      sentences returned row 0's translation for all 4 (our `translateBatch`
+      passes the batch straight to the translation pipeline, so it is

+- [ ] `src/worker/opusMt.ts` still forces `graphOptimizationLevel: "basic"`

 - [x] The server API still accepts `task: "translate"` with large-v3-turbo
       (only the UI hides it, D-044). — Fixed: `POST /api/transcribe` and the
       live WebSocket answer 400 via `translateNotSupported` (src/server/transcribe.ts).
