docs(sec): post-reparse verification and cutover recommendation

Closes the parity investigation: prod reparse runs 6+7 reconciled against the
dry run, the collision check that caught the BEN regression (and its residue --
36 historical 53-week-drift rows, deliberately left), and the 2026-07-24 parity
report diffed against the 2026-07-23 baseline. Candidate coverage 482 -> 504 of
511 with the gap fully explained (PSKY/Q new registrants, FITB guard-tripped
with no revenue), agreement unchanged where both sides exist, and the remaining
deltas are documented definition differences. Includes the after-report and a
correction to the seventh pass (FITB loses its score, not just one input).
Recommends approving the A5 cutover with KLAC as the one carried caveat.
