  "note": "Yahoo listed the year-end capital-gain distribution in BOTH the dividend and capitalGains event files. Expressed as layout-agnostic invariants because a 2026-08 re-download shows Yahoo no longer returns capitalGain events for this fund at all (the dividend stream still carries the year-end rows): 'dedup' keeps at most one copy of each (date, amount) (the capitalGain copy when both files carry it; the lone dividend copy otherwise); 'drop_capg_copy' drops the spurious capitalGain row on a date where the dividend row is the true distribution (any amount). Official per-share data (JPMorgan 497, filed 2025-11-03, Class I, FYE June 30): FY2025 1.37, FY2024 2.03, FY2023 4.86, FY2022 6.78, FY2021 6.89 - local sums after dedup match every one (1.368, 2.029, 4.859, 6.785, 6.889). 2006-12-15 (div 0.207 vs capg 0.141) and 2019-08-08 (div 4.138 vs capg 4.077) keep the dividend amount per the pattern confirmed on all other verified same-date pairs; pre-2012 years have no official totals (the 2021 497 is delisted from SEC Archives) - mechanism-inferred. 'history' patches the 2020-12-11 Adj Close cell: Yahoo dated the 6.824 distribution on the 12-11 record date but the market went ex-div on 2020-12-14 (close 30.10 -> 23.22, i.e. -6.88), so the raw Adj Close column spiked +29.3% on 12-11 and snapped back -22.9% on 12-14; setting 12-11 to the 12-10 value (11.247889) removes the bogus 3-day wiggle (cumulative return unchanged). adj-close repair: Yahoo dated a distribution on 2020-12-11 (record date) but the price went ex-div on 2020-12-14 (close 30.10 -> 23.22, drop ~6.824); the raw Adj Close column spiked +29.3% on 2020-12-11 and snapped back later. Cells in [2020-12-11, 2020-12-14) rescaled by (1-f) so the adjusted path is smooth; cumulative returns are unchanged. Mechanism: scripts/fix_adj_misalign.py, scan: reports/adj_misalign/scan.md. Distribution date moved 2020-12-11 -> 2020-12-14 (true ex-div date, close 30.10 -> 23.22 for JLPSX / 30.29 -> 23.40 for JLPYX): Yahoo dated the 6.824 capital-gain distribution on the 12-11 record date, but the after-tax model reinvests at the event date's raw close, so the cash flow must sit on the day the price actually dropped. Ops: remove both file copies on 12-11, add the capitalGains copy on 12-14 (kept in capitalGains so it is taxed at the cap-gain rate, matching the 497's CG 6.82 / NII 0.07 split).",
