+"""TelegramAdapter.send_draft MarkdownV2 formatting parity.
+
+Bot API 9.5 ``sendMessageDraft`` powers the animated streaming preview in
+DMs.  The regular ``send`` path renders with MarkdownV2, so the draft must
+too — otherwise the live preview streams as raw text and the final
+``sendMessage`` snaps into formatted output, producing a jarring visual
+shift at the end of the response (reported by an external user, May 2026).
+
+These tests pin:
+  1. The happy path passes ``parse_mode=MARKDOWN_V2`` with format_message'd
+     text (formatting parity with the final message).
+  2. A MarkdownV2 BadRequest triggers a single plain-text retry rather than
+     killing draft streaming for the whole response.
+  3. A non-BadRequest failure propagates so the caller falls back to edit.
