Python no longer generates s-expression strings. All SX rendering now goes through render_to_sx() which builds AST from native Python values and evaluates via async_eval_to_sx() — no SX string literals in Python. - Add render_to_sx()/render_to_html() infrastructure in shared/sx/helpers.py - Add (abort status msg) IO primitive in shared/sx/primitives_io.py - Convert all 9 services: ~650 sx_call() invocations replaced - Convert shared helpers (root_header_sx, full_page_sx, etc.) to async - Fix likes service import bug (likes.models → models) Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
