On MemWal, Rememe, Walcraft, and Nautilus, the product reads PostgreSQL. The chain is the record we index.

The screen does not read the chain

Claude Code, Cursor, and Codex are how I work. A change ships after I have checked correctness and performance.

The agent writes the diff. I still own it.

MemWal stores encrypted agent memory on Walrus and serves search from PostgreSQL. The TypeScript SDK never talks to the chain for a query.

The post lives on Walrus. The rules live in Move. The feed the app renders is an API in front of both.

We replaced Apache Solr with Elasticsearch, then ranked keyword and semantic results together. Kibana was how we saw the index.

At Pascalia Asia, content came in as RSS, moved through Airflow, and left through REST, webhooks, and Apple News.
