Measures R1 (reversed tips) and R2 (Square service charges) over 3,342
client-days of real production data, restored from backup point 209608347
(newest transaction 2026-08-14 22:52).
R2 clears 307 client-days with zero regressions, which is the gate the plan set
for it. R1 clears 78 with 2 regressions, both days that balanced only because
two errors cancelled, and both on clients that share a Square location.
After both fixes, 98.6% of the remaining dollar error sits in the 10 contended
client pairs — Phase 0's to fix, not a calculation defect. Outside those, the
entire residual is $73.98, of which all but six client-days is sub-10c register
rounding. The three predicted material days reproduce to the cent.
Also records an amendment to Phase 1: 2,122,161 charges (12.8%) carry neither
:charge/client nor :charge/location, so the re-key cannot scope them from the
entity. They are payout-path stubs and order-referenced tenders; none are
orphaned, so scoping must come from the referencing order or expected-deposit.
