 ## Known Limitations
 
+- **Incomplete syntax context**: Treesitter parses each diff hunk in isolation
+  without surrounding code context. When a hunk shows lines added to an existing
+  block (e.g., adding a plugin inside `return { ... }`), the parser doesn't see
+  the `return` statement and may produce incorrect highlighting. This is
+  inherent to parsing code fragments—no diff tooling solves this without
+  significant complexity.
+
 - **Syntax flashing**: `diffs.nvim` hooks into the `FileType fugitive` event
   triggered by `vim-fugitive`, at which point the buffer is preliminarily
   painted. The buffer is then re-painted after `debounce_ms` milliseconds,
