Bridge active inference theory with robot control using K-Scale's JAX/MuJoCo stack. Use when connecting predictive coding to locomotion policies, mapping KL divergence minimization to RL training, applying mean field approximation to robotics state estimation, or implementing sim2real as inference about future observations.
Implement affective valence as directional derivative of interoceptive energy landscapes for AI alignment. Use when building alignment-aware RL agents, validating GF(3) conservation in reward signals, training Langevin-based policies, or analyzing fold-change detection signals in POMDP environments.

Trit: 0 (ERGODIC - coordinator) Color: #26D826 (Green) Principle: Chain operations via derivational succession, not temporal
The cat skill implements the |> pipe operator using derivational chaining instead of temporal succession. Each pipe stage advances a seed: seed_{n+1} = f(seed_n, trit_n).
pipe_chain: A |> f |> g |> h
seed₀ → f(seed₀, trit_f) → seed₁
seed₁ → g(seed₁, trit_g) → seed₂
seed₂ → h(seed₂, trit_h) → seed₃
GF(3) conservation: Σ(trit_f + trit_g + trit_h) ≡ 0 (mod 3)

category-theory: 139 citations in bib.duckdbThis skill connects to Software Design for Flexibility (Hanson & Sussman, 2021):
Concepts: generic arithmetic, coercion, symbolic, numeric
cat (−) + SDF.Ch3 (○) + [balancer] (+) = 0
Skill Trit: -1 (MINUS - verification)
Generic arithmetic crosses type boundaries. This skill handles heterogeneous data.
This skill maps to Cat# = Comod(P) as a bicomodule in the equipment structure:
Trit: 0 (ERGODIC)
Home: Prof
Poly Op: ⊗
Kan Role: Adj
Color: #26D826
The skill participates in triads satisfying:
(-1) + (0) + (+1) ≡ 0 (mod 3)
This ensures compositional coherence in the Cat# equipment structure.
