compare-sales-summaries diffs summaries between two points in the same database using as-of, so a recompute can be audited against exactly what was there before without a snapshot or scratch copy. It answers a question that balance-status counting hides: a day can stay balanced while its line amounts move, which is a real change to the books even though no red turns green. Amounts are compared at the cent so floating-point noise does not read as a change. Run over 2026-07-15 to 08-13 against production's own summaries at basis-t 209608347: out of balance -> balanced 309 balanced -> out of balance 0 balanced -> balanced, numbers moved 237 no summary in production 4,058 Broken down by fix, neither calculation change touches a healthy day: R1 fixes 86 with 0 unbalanced and 0 balanced-day edits, R2 fixes 276 on the same terms. Every one of the 237 balanced-but-changed days comes from the data work, which is also the only step that unbalances anything — 19 days, all of them absorbed by R1 and R2, which is why the end-to-end count is zero. The 4,058 missing summaries include eight consecutive days, Jul 30 to Aug 6, missing for all 210 clients — the coverage hole the plan predicted from the scheduler's seven-day lookback, confirmed here independently from the data.
