The points-exchange desc was stripped at all three layers: no sanitize_type on the schema fields (save ran sanitize_textarea_field), the runtime re-ran the same strip, and the points modal escaped it with esc_html. The reference theme declares sanitize=false and concatenates the value raw into the modal.
- Schema (SPA + PHP): sanitize_type html, rows 2, help text noting HTML support
- PaymentRuntime: output via wp_kses_post
- VipServiceModal points modal: render via wp_kses_post instead of esc_html
Verification: new contract test covers schema/runtime/modal layers; node --test tests/**/*.test.cjs 641/641 pass; php -l clean on both PHP files.
