 ## Pending / TODO
 
-- [ ] Wire `style_href` via `<svelte:head>` in print page
-- [ ] Add `duplex` to `properties_to_save` once backend field exists
-- [ ] Add `duplex`-driven `print:hidden` to `badge_back` section in `ae_comp__badge_obj_view.svelte`
-- [ ] Make `layout` field drive actual card dimensions in the badge component (currently hard-coded)
-- [ ] Remove dead `exhibitor_info` / `presenter_info` / `staff_info` / `vip_info` / `vote_info` `{#if}` blocks from `ae_comp__badge_obj_view.svelte`
+- [x] Wire `style_href` via `<svelte:head>` in print page — done in `print/+page.svelte`; also in `properties_to_save`. (2026-03-18 verified)
+- [x] Add `duplex` to `properties_to_save` — done. (2026-03-18 verified)
+- [x] Add `duplex`-driven suppression to `badge_back` section — done in `ae_comp__badge_obj_view_v2.svelte`; `show_badge_back` derived from `duplex` field. Note: v1 (`ae_comp__badge_obj_view.svelte`) was archived to `~/tmp/gemini_trash/`; v2 is canonical. (2026-03-18 verified)
+- [ ] Make `layout` field drive actual card dimensions in the badge component — currently the Zebra ZC10L layout CSS (`badge_layout_zebra_zc10l_pvc.css`) sets dimensions correctly via `[data-layout="..."]` scoping, but fanfold layouts still use Tailwind defaults. Needs proper CSS for each layout code.
+- [ ] Remove dead `exhibitor_info` / `presenter_info` / `staff_info` / `vip_info` / `vote_info` `{#if}` blocks from `ae_comp__badge_obj_view_v2.svelte` (if they were carried over from v1)
 - [ ] Improve `ae_comp__badge_template_form.svelte` to edit all relevant fields (currently minimal)
