The mood page called the plain `pearsonCorrelation` — strength banded from
|r| alone above a floor of five pairs, no significance test — so five days
of noise sloping the right way arrived at the reader as a "Strong" badge,
with n and r behind an info icon. The guarded twin was written for exactly
that failure and names it in its own comment, and the weight, blood-pressure
and mood-status surfaces had already moved onto it. The mood page had not.
Route the page's five cross-metric channels through
`significantPearsonCorrelation` (n >= 20 AND p < 0.05) and carry the reason
a pairing was refused, so the card can distinguish "still building" from
"twenty days and nothing in them" instead of showing the same blank for
both. New copy in all seven locales.
Add a structural guard that fails when a new caller of the unguarded helper
appears outside a written allowlist. Two callers remain on it, each named as
open work rather than as a blessing: the /insights envelope and the AI
feature payload both still band at n >= 5, and moving them changes payload
shapes their own tests pin.
