Side A is a substantial, coherent refactor that removes '@' sigil ambiguity from wire identities, splits canonicalization/identity concerns into dedicated modules, updates callers across server/CLI/tests, and adds regression tests validating the new invariant. Side B is a one-line placeholder file addition with no functional code, tests, or explanatory value.
Commit A is a substantive architectural refactor: it extracts canonical_path/identity modules, enforces strict stored-form wire identity (no @), makes delegate optional, and stops the reducer from rewriting identities—clear lasting design. Commit B only adds a one-line seed.tdsl (“open webui”) with no structural or corrective impact.
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.
