docs(sec): fundamentals parity root-cause findings

Browse Source

Nine-pass investigation of the 2026-07-23 A5 parity report: for each coverage
gap and wrong value, the root cause traced against live SEC company facts, the
fix, and its live-data validation. Also records the decisions taken (weighted-
average share fallback, keep ASC-606 revenue basis, basic-EPS fallback, keep the
25% split-guard threshold) and what remains genuinely unfixable from this data
(KLAC post-filing split, BRK-B dimensional share count). Includes the source
parity report the findings analyse.
