+- User-attached context (inline code comments, terminal selections, browser
+  annotations, PR comments/checks): `UserContextPart.tsx`. `UserTextPart`
+  routes to it when the part's metadata carries an `openchamberContext`
+  payload (see `lib/messages/contextParts.ts`, which owns both the send-time
+  builder and the read-back parser). Linked GitHub issues/PRs are instead
+  converted to link file-parts in `normalizeUserDisplayParts.ts`. Legacy
+  pre-metadata messages still render via text sniffing (`<terminal_context>`
+  blocks, `GitHub issue context (JSON)` prefixes).
