-- t-paliad-116 B: paliad.event_deadlines.notes_en column + DE/EN swap
-- for the three rows that ship English text in the (DE-named) notes
-- column.
--
-- The DTO has long emitted `notes` directly into the EN render, so the
-- pattern matches t-112 mig 032 for deadline_rules: add a parallel
-- notes_en column, render path prefers _en when locale=EN and falls
-- back to notes (DE) when NULL.
--
-- Three rows currently leak English into the DE locale (ids 50, 52, 70):
--   50, 52: "Or 20 Working days, whichever is longer"
--   70:     "The 262.2 application can also be filed for opponent
--           submissions to protect confidential information disclosed
--           by the opponent."
-- For those rows we (1) copy the existing English string verbatim into
-- notes_en, and (2) overwrite notes with the proper DE translation so
-- the DE locale stops leaking.
