+### Fixed
+- **Copy for LLM rendered literal `\n` instead of newlines** — The `j` (escape_javascript) helper in the view escaped newlines for HTML attribute safety, but the clipboard received literal `\n` text. Now unescapes before copying so markdown renders correctly in editors and LLMs
+- **Copy for LLM crashed on related errors** — `related_errors` returns plain `ErrorLog` objects, not wrapped objects with `.similarity`/`.error` accessors. Now handles both formats gracefully
+- **Instance variable `_self_class` rendered as raw hash** — When `_self_class` is stored as a serialized hash (`{"type":"String","value":"QuestService"}`), the formatter now extracts the value correctly instead of dumping the hash
