Comment:
**syntax:** Invalid syntax: literal `+` characters at the start of lines

This entire code block has diff markers (`+`) that were not removed during merge/patch application. These are literal characters in the source file, not just visual diff indicators. This will cause compilation to fail.

Remove the leading `+` characters from all lines in this range (92 lines total from line 1263-1355).
