openai/gpt-chat-latest → A (100:1)

Side A introduces a substantive architectural refactor by separating identity parsing and path canonicalization into dedicated modules, enforcing strict stored-form identities without '@' in APIs, making delegate identity optional, and updating the reducer and API boundaries to stop rewriting identities. It also propagates these semantics consistently across authentication, ingest, feed, HTML display, types, and tests, whereas Side B only adds a one-line seed file containing "open webui" with no evident functional impact.
