 - promote fixture verification into automated test coverage
 - add regression checks for template mappings, storage persistence, and permission enforcement
 
+### Current PDFME template coverage
+
+Current:
+
+- payment, warranty, delivery, and extra topic sections now flow through the dynamic `topic` / `data_topic` engine on page 2 instead of fixed placeholder fields
+- approval signature fields are not mapped yet
+- signature placeholders `app1/app2/app3` currently rely on safe fallback mapping and still need Task H.3 strategy for real names and positions
+
+Future:
+
+- keep validating pagination and closing-block placement against production designer expectations for large topic sets
+- map approval signature fields when approval-to-document ownership is formalized
+- add fixture-backed end-to-end PDF generation verification in CI once a stable runtime path is available
