The field join (task 5.11) seeded every parameter of every method in the
file, so every setter made its field a source. Adjudicated on PMPro, six of
eight false SQL injections in a 1-in-5 sample were object fields holding
database or internal values ($this->membership_id, $morder->user_id).

A parameter now seeds the join only where some call site passes it request
data without a sanitizer on the way (memoised per method and index); a
request source read in the file still seeds as before. A real-Joern control
covers both directions -- a setter only given a constant stays quiet, a
constructor handed $_GET (the CVE-2023-6559 shape) is still found -- and
fails on the old query with exactly the PMPro false positive.
