Summary

• Recognize C# raw string literals with three or more quote delimiters before ordinary string/comment matching.
• Prevent // inside a raw string containing embedded quotes from hiding later code on the same line.
• Add a regression test that verifies real code after the raw string remains visible while a true trailing comment is ignored.

Why

C# 11 raw strings may contain unescaped quote characters. The previous regular-string pattern could terminate early, then treat // inside the remaining raw-string content as a comment start and erase subsequent code evidence.

Boundaries

• This remains a bounded literal scanner, not a full C# parser.
• No change to Lua handling, token semantics, or advisory status definitions.
• No public API or schema version change; all findings remain non-blocking.

Validation

Python 3.10–3.13, MCP stdio E2E and Sample Project Advisory.
