SPRT on puppets

[Competitive Rock-licker (milky)]

SPRT is written below my DP bar on some of my puppets. Can someone tell me what it means?

Thanks

Support I believe, it should mean a puppet is in the secondary slot of the pact and can be swapped in. IIRC the SPRT message will be blue at full hp, then shift to green, yellow, red, or blacked out depending on the back up puppets HP value.
