Chunk 13.0

## Summary of Current Session The user confirmed that the `pac-l-gw.devtty.eu` Lotus gateway is now operational. The assistant verified gateway connectivity (successfully retrieved chain head at height 5,729,846) and checked the deal tracker logs on the kuri nodes. The deal check cleanup loop was completing successfully (~35-43 seconds), but no GBAP calls or deal proposals were initiating for Group 1, which has ~30GB ready for deals (state 3 = `GroupStateLocalReadyForDeals`). ## Debugging and Resolution The assistant identified the root cause through progressive debug logging: while `makeMoreDeals` was being called and passing the `canSendMoreDeals` check, the GBAP (Get Best Available Providers) call to CIDgravity returned zero providers. Direct API testing revealed the issue - the GBAP request was missing the required `removeUnsealedCopy` field, causing the API to reject the request with an error. Even after adding the correct field, CIDgravity returned `NO_PROVIDERS_AVAILABLE` for this piece CID, explaining why no deals were being made despite the group being ready and the gateway functional. ## Key Achievements and Themes The session focused on debugging the stalled deal flow after fixing the Lotus gateway connectivity. Key actions included adding strategic info-level logging throughout the deal-making pipeline (from `makeMoreDeals` entry through GBAP provider retrieval) and iterative rebuild/deploy cycles to trace the exact failure point. The primary blocking issue shifted from infrastructure (gateway availability) to CIDgravity API integration parameters (missing required fields) and ultimately to a lack of available providers for the specific deal parameters. Additional findings included a YugabyteDB schema issue (`column "piece_cid" does not exist` in `claim_extender.go`) that may affect deal piece mapping queries.
