What the number is

A 0–100 composite from named factors (identity, maintenance, adoption). Every factor can appear in trust_factors on the API.

What changed in v3.2

Uncorroborated identity rows are capped. Look-alike brand namespaces can be penalised. Self-attested publisher bios are not free points.

How not to use it

Do not sort solely by score and install #1 blindly.
Do not treat 80 as “secure.”
Do not ignore Official/Verified when they disagree with the number.
