 A failing or unauthenticated advisor is logged as a warning and simply excluded — it never fails the run. Remove an entry (or the whole `advisors:` list) to disable multi-agent mode.

-Set `archive.enabled: true` in `config.yaml` to save each run's fetched data, full prompt (including any advisor section), raw and parsed analysis to `archive.dir` (default `~/.local/state/stonks/runs`), one timestamped subdirectory per run: `fetched.json`, `prompt.txt`, `analysis_raw.md`, `report.md`, `recommendations.json`. Useful for debugging prompt or parsing issues without reproducing a live run. Off by default — these accumulate over time with no automatic cleanup.
+Every run saves its fetched data, full prompt (including any advisor section), raw and parsed analysis to `archive.dir` (default `~/.local/state/stonks/runs`), one timestamped subdirectory per run: `fetched.json`, `prompt.txt`, `analysis_raw.md`, `report.md`, `recommendations.json`. This is always on — besides being useful for debugging prompt or parsing issues, the next run reads back `report.md` from the most recent subdirectory so it can avoid repeating unchanged commentary from ~5 hours ago. These accumulate over time with no automatic cleanup.
