`[2026-09-27]` Worldtree reward path: code + config live (Prime)

(Moved out of the in-flight section at the 2026-10-06 snapshot.)

d8726a13 (Domari's Skywork/Selene fix) was ALREADY on origin/main when Prime said to push it: it was pushed as part of 79cce92f at 1221. Demo runs image 79cce92f. Personal still runs 51168a2e, which is older and lacks the fix; its image follows worldtree CI, never a manual up.
deploy-wt-config deployed demo and personal (1437): providers.yaml reward_models.scalar-judge (6d4ac44), plus a77639d's corrected selene description, which had never reached the hosts. Both are healthy, with 0 drift. It is inert on personal until that image picks up d8726a13.
worldtree-instance-configs: its 6 long-unpushed commits (53349f8…6d4ac44, Aug 2 to Sep 27) were pushed on Prime's go-ahead (a9d091e..6d4ac44). Origin, the repo and both hosts now agree.
