List articles from a buyer's licensed catalog via GET /enterprise-license (Phase 10 + 11). Content contract: AI training orders include full content_body for the back catalogue up to the order date (content_access 'included'). Every other order is discovery-only (content_body null): AI answers monthly and client display fetch text per article via get_content (content_access 'retrieval_per_article'); pay-per-request fetches billed snippets via get_content (content_access 'metered_per_call'). Returns JSON-format response with paginated articles. Use `since` (ISO 8601) for delta-feed polling — only articles published after the timestamp. Use `cursor` for pagination across pages. Requires OPEDD_ACCESS_KEY (ent_* enterprise access key). For larger bulk corpus pulls, use stream_feed_ndjson (up to 1000 articles per call vs 200 here).
