Records the pattern that came out of the refactor (path segment vs query param
vs stays-a-button), the grep that re-checks it, and the fact that BackButton —
which this section named as a standard building block — was dead and is gone.
Also folds in the two selections the audit never listed: the email folder and
the Soulseek room/peer rails. Neither was in the findings table; both were found
by sweeping for useGlobal<//useState after the listed rows were closed, which is
worth recording as the reason the table alone was not enough.
