🟡 Medium src/nativeMarkdownText.ts:488

On Android, copying a descriptive file link drops its prose label from the canonical Markdown link, producing text such as validates the input [(example.ts)](<...>) instead of a link labeled validates the input. appendChildren emits the label as an ordinary href run, while line 488 emits only the filename suffix as the fileIcon run that nativeMarkdownContextCopyRanges canonicalizes. Keep the descriptive label and filename in the same canonicalized file-link run, or update the copy-range logic to include the preceding label run.

Keep inline paths inside descriptive labels as code text.

MarkdownLinkContext does not protect file-link labels. The file-link branch returns through fileLinkChip before it creates the generic link context, and MarkdownCode does not read that context. The inline path becomes a nested file trigger. Clicking it opens example.ts instead of the outer link target guide.md.

Wrap retained children in MarkdownLinkContext and skip inline-code file-chip conversion in that context.

Suggested fix 
   const descriptiveContent = children ? (
     <>
-      {children} (<ContextChip kind="mention">{chip}</ContextChip>)
+      <MarkdownLinkContext value>{children}</MarkdownLinkContext>{" "}
+      (<ContextChip kind="mention">{chip}</ContextChip>)

Review comment at @apps/web/src/components/ChatMarkdown.tsx at line 3144:
Preserve inline paths in descriptive file-link labels as text instead of
converting them into nested file chips. In the file-link branch that renders
retained children, wrap them in MarkdownLinkContext, and update MarkdownCode to
skip inline-code file-chip conversion when that context is active.
