- BaseKVStorage / BaseEventStorage / BaseDocumentStorage define the API once; implementations provide only raw primitives (client and server share an API) - Drop KV indexes, query planner, unique indexes; document stores take index fields - Escape every char <= '/' so child keys stay contiguous; skip-scan is now simple - Event-sourced documents = event storage + any document store for projections - New folder layout (kv-storage, event-storage, document-storage, utils); tests only in test/ Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_017Qxbkp4tA7G5SCWjzWuxmE
