Side B introduces substantive infrastructure: a new RocksDB-backed `durable` workspace crate with persistent collections, moves raw entity JSON into a dedicated `EntityStore`, and changes event log startup from loading all events into memory to streaming replay via `EventLog::replay`, reducing memory usage and improving scalability. Side A primarily restructures the CLI and documentation (renaming `ingest` to `forum post`, adding subcommands, updating help text and tests) with only minor behavioral adjustments, making it far less impactful in long-term project architecture.
