Greg Pomerantz e15cb51390 Corrections: resolve the 7 stale mismatches via the Yahoo double-listing pattern
Scanning the verified funds for same-date div/capg pairs showed the Yahoo
double-listing mechanism in every one of the 7 'mismatch' stale funds, and
the official fiscal-year totals pin down which amount is true:

- identical-amount pairs (JLPSX, GDEUX, GSOUX, FAEVX, CVSIX, FZAGX): the
  year-end distribution is in both files; keep the capitalGain copy,
  remove the dividend copy (GDEUX: FY2021-08 1.73 = 1.625+0.115 and
  FY2022-08 0.39 = 0.348+0.036 after; JLPSX/GSOUX/FAEVX/CVSIX same)
- differing-amount pairs (OTCRX, SHXIX, FZAGX, FGIZX, CVSIX): the
  dividend-file amount is the true one in every officially-verified case
  (OTCRX FY2023 0.85 = 0.852488, SHXIX FY2023 1.01 = 1.0078, FZAGX all
  four FYs exact); the capitalGain row is the spurious copy

After corrections GDEUX/SHXIX/CVSIX/JLPSX verify 'ok' against their
filings. The same pattern is extended to these funds' pre-2021 history
(marked mechanism-inferred in the correction notes). Remaining residuals:
FAEVX and FGIZX are also missing regular quarterly dividend rows in the
Yahoo dump (official FY totals exceed local even after dedup) - needs the
funds' per-date distribution archives; FIKAX's official extraction is
ambiguous (systematic ~0.12/yr offset = wrong class table in the
500-fund consolidated Fidelity N-CSRS).

(1) 2008-12-18 0.292 (dividends): duplicate date of the real 0.641 distribution; official FY2009 (FYE 10-31) = 0.81 = 0.641+0.076+0.050+0.045 and FY2008 = 0.51 = 0.241+0.090+0.090+0.089 both balance without it. (2) 2023-12-21 0.510 (capitalGains): official FY2024-10 = 0.79 = 0.691+0.017+0.042+0.042, so the 0.510 cap-gain row on the same date as the 0.691 dividend is the spurious one.
