## Result

- Real OpenRouter API call verified for `qwen/qwen3-embedding-8b`.
- Pilot backfill completed through `scripts/backfill_vectors.py --provider openrouter --model qwen/qwen3-embedding-8b --dim 4096 --limit 100 --quiet`.
- Current Qwen3 shadow-vector count: `101` docs, `1878` chunks.
- Dimension check: min `4096`, max `4096`.
- Sample `vector_search_documents` call returned top-3 rows.

## Notes

- OpenRouter key was loaded transiently from existing local env files and was not printed or committed.
- Runtime audit file `data/action_lifecycle_audit.jsonl` remains the only dirty git file and is unrelated.
- Next engineering improvement: add skip-existing and chunk-limit controls to backfill script before larger full backfills.
