- Add proper blank lines (\n\n) before mode headings in render_runtime_policy_reference (CommonMark/GFM compliance). - Demote subheadings in agent.md from ##### to ###### so they nest correctly under the demoted main heading. - Add debug_assert! in taxonomy_body() to loudly fail when render_core_tool_taxonomy_block format changes, preventing silent heading-hierarchy breakage.
