Comment-residue hash reader ignores escapes inside double-quoted values (false positive) #360

Finding

The comment-residue gate's hash-comment reader (tests/OpenCode.Sdk.Tools.Tests/CommentResidue/CommentReader.cs, HashComments) closes a quoted value at the next matching quote character and ignores escapes. A valid YAML line such as

name: "value\" # Q123"

is therefore read as the value "value\" followed by the comment # Q123", and the gate reports Q123 from inside a string. This is a false positive, so it fails loud rather than open. It predates TST-E0b-2, and the TST-E0b-2 review (Sol, run tst-e0b2-review) found it. The review fix in that PR was limited to the reviewed defect (CR-only analyzer config lines), because a lexer rewrite was outside its approved scope.

Disposition

Not fixed in TST-E0b-2. Candidate for the Tools.Tests oracle sweep: honour backslash escapes inside double-quoted YAML scalars, with the line above as the red case.
