Root cause: association only ever looked at the dedicated submitter_email
(public 'your email' box / auth email). A form that asks for email as an
ordinary field stored it in answers, so submitter_email stayed null and
nothing matched -- 'Re-link' reported 0 ('already linked') and the
submission never appeared under the member. New pure deriveSubmitterEmail
(explicit > email-type field answer > any email-looking answer; trimmed
lowercase) + 5 tests. submitForm now derives + persists submitter_email
from answers; relinkAllSubmissions re-derives per submission from its
form_snapshot and backfills member_id + submitter_email for existing
rows. Suite 469.
