I can't tell if this is an explicit rules change between Basic and Beta or just inconsistent text, but do you add Constitution score or Constitution modifier to base class HP for starting HP?

7. Set Starting HP
Your starting HP is equal to your class's base HP+Constitution score.

This is right under a table that distinguishes stat scores and modifiers.

However, all of the class chapters say +CON HP, e.g., Bard

Your base HP is 5. You start with 5+CON HP.

The Bard 1.1 playbook spells out the stat, meaning the score,

Your base HP is 5. You start with 5+Constitution HP.

but the other playbooks have the abbreviation, but not in small caps. Does this mean the score or the modifier?

Your base HP is 6. You start with 6+Con HP.
