openai/gpt-chat-latest → A (3:2)

Side A makes a lasting architectural improvement 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`) across the API and shared data structures. This centralizes path identity, reduces duplication, and makes many RPC/JSON interfaces correct-by-construction, whereas Side B mainly improves offline tooling with faster log scanning, richer parse errors, and a useful `compile --ingest` workflow but does not affect the project's core data model as broadly.
