Heightening cantrips / focus powers with archetype

[Mista Moore]

How do cantrips and class focus powers heighten?

For example lets say I take sorcerer dedication at 2nd level, choose the angelic bloodline and receive 2 cantrips, at 4th I take basic bloodline spell to get angelic halo, and then at 6th and 8th I take basic spell casting to unlock 1st and 2nd level spell slots. Does that mean when I cast the cantrips and bloodline power are they heightened to 2nd level, half my class level rounded up, or not at all?

Cantrips and focus spells are always auto heightend to half your character level rounded up.

so they are basically always max level, as an example at 9th character level they are 5th level spells.

A cantrip is always automatically heightened to half your level, rounded up. For a typical spellcaster, this means its level is equal to the highest level of spell slot you have.

Focus spells are automatically heightened to half your level rounded up, just like cantrips are.
