Side A ships a real, non-trivial architectural feature (a unified POST /ui endpoint with a generic form-template hole-filling mechanism, wired into the router and shared with existing web_post handlers, plus tests), directly improving the production HTML app. Side B adds a useful but purely dev-tooling side binary (sorterc) for offline DSL compile/lint, valuable for developer workflow but not part of the core product runtime, and largely reuses existing server logic rather than introducing new core capability.
