Status: Production Ready (v3.0 - Cat# Integration) Trit: 0 (ERGODIC - measurement/observation) Principle: S(x) = -log₂(P(x|attention_mode)) Frame: Tri-channel prediction evaluation with AGM belief revision + Cat# bicomodule structure
Behaviour Surprisal Analysis calculates information-theoretic surprise between predictions and observed outcomes using three complementary attention channels mapped to Cat# = Comod(P) structure:
| Channel | Trit | Home | Poly Op | Kan Role | Description |
|---|---|---|---|---|---|
| Direct (α) | −1 | Span | × (product) | Ran_K | Exact artifact matching |
| Diffuse (β) | 0 | Prof | ⊗ (parallel) | Adj | Thematic/structural matching |
| Meta (γ) | +1 | Presheaves | ◁ (substitution) | Lan_K | Capability/infrastructure tracking |
Total Surprisal = α·S_direct + β·S_diffuse + γ·S_meta
where α + β + γ = 1 and typically α=0.3, β=0.5, γ=0.2
This skill connects to Software Design for Flexibility (Hanson & Sussman, 2021):
Concepts: eval, apply, interpreter, environment
behaviour-surprisal-analysis (−) + SDF.Ch5 (−) + [balancer] (−) = 0
Skill Trit: -1 (MINUS - verification)
Evaluation interprets expressions. This skill processes or generates evaluable forms.
The Direct and Meta channels form a Galois adjunction through the Diffuse bridge:
α (abstract)
Direct ─────────────→ Diffuse
↑ │
│ CatSharp │ γ (concretize)
│ Scale │
└──────────────────────┘
Meta
GF(3): (−1) + (0) + (+1) = 0 ✓
Each channel lives in a specific Cat# home:
┌────────────┬─────────────┬──────────┬───────────────┬────────────┐
│ Channel │ Poly Op │ Kan Role │ Structure │ Home │
├────────────┼─────────────┼──────────┼───────────────┼────────────┤
│ Direct │ × (prod) │ Ran_K │ cofree t_p │ Span │
│ Diffuse │ ⊗ (para) │ Adj │ bicomodule │ Prof │
│ Meta │ ◁ (subst) │ Lan_K │ free m_p │ Presheaves │
└────────────┴─────────────┴──────────┴───────────────┴────────────┘
Predictions and observations form bicomodule pairs. Coherence is verified by:
Surprisal values map to pitch classes via the CatSharp scale:
| Trit | Pitch Classes | Chord Type | Hz Range |
|---|---|---|---|
| +1 (PLUS) | {0, 4, 8} | Augmented triad | C-E-G# |
| 0 (ERGODIC) | {3, 6, 9} | Diminished 7th | D#-F#-A-C |
| −1 (MINUS) | {1,2,5,7,10,11} | Fifths cycle | C#,D,F,G,A#,B |
;; Surprisal → Pitch class → Frequency
(defn surprisal->pitch-class [surp]
(mod (Math/round (* (min surp 10.0) 1.2)) 12))
(defn pitch-class->freq [pc]
(* 261.63 (Math/pow 2 (/ pc 12.0)))) ;; C4 = 261.63 Hz
Enable with --sonify flag to hear the surprisal as tones via sox.
Based on Baker 2023:
K * φ = (K − ¬φ) + φ (Levi Identity)
Predictions ranked by entrenchment:
(defn kappa-rank [belief]
(- (Math/log (/ 1 (max 0.01 (:confidence belief))))))
Lower κ = more entrenched = harder to revise.

The tri-channel Cat# model reflects:
GF(3) conservation IS the naturality condition of Cat# equipment:
For a triad (s₋₁, s₀, s₊₁):
Ran_K(s₋₁) →[bicomodule]→ s₀ →[bicomodule]→ Lan_K(s₊₁)
The commuting square:
G(f) ∘ η_A = η_B ∘ F(f)
Becomes the GF(3) equation:
(−1) + (0) + (+1) ≡ 0 (mod 3)
