Johnson-So O/S has the opposite sign (Q5-Q1 -11.4%/yr, t -1.63) and
correlates -0.65 with the momentum score; unsigned put/call is flat
(t 0.42). Neither gated signal passes; keep collecting, retest at ~5 years.
The data handling was fixed after a coverage check of the panel, before any
return was computed: stock volume on every day from stock_raw, and a day
without bars counts as 0 contracts only inside a name's bar span (outside it
the options traded under an older ticker or the root's history starts later).
