Docs only: a short Open items list at the end of the Experiments section, so someone resuming this work (including me) can see where to pick it up. The notes were previously scattered across the experiment READMEs and outside this repo.

Five items, none started in the repo:

1. Scale test: begun outside this repo with EU legal acts from Cellar and stopped; embedding runs at about 5 chunks per second on the Apple-GPU Mac used here, which overheats under sustained load, so only about a 4x step is realistic there.
2. Local re-ranker: trails Jev by about 5 questions; the local LLM judge was stopped before a result, so the wording idea is untested.
3. Jev's run-to-run variation: three passes only.
4. The 28 first-set questions drafted from the searched chunks.
5. Cross-document answers: not covered by any experiment.

The figures repeat what the experiment READMEs already say (5.2 chunks per second, about 17,500 acts, about 250,000 chunks in total, 5 questions behind). No link points to the scale-test repo because it is local only. No code changes.
