Side A performs a substantial architectural consolidation by moving canonical path normalization and URL construction into a shared `types::paths` module, replacing ad hoc string helpers with typed wrappers (`GardenItemUrl`, `ForumThreadUrl`, `TildeOntologyPath`) throughout the server and API models. This centralizes path identity, reduces duplication, and makes RPC/serialization use correct-by-construction types, whereas Side B is a broad reconfiguration introducing a new tree/journal architecture and UI changes but also many placeholders (e.g. stubbed Reddit fetch), renames, and incomplete infrastructure whose lasting value is less clearly realized in the patch itself.
