The Core Idea — γ₁-Distance
Every ARC task has a distance from the floor.
The floor is γ₁ = 14.134725141734693 — the first non-trivial zero of the Riemann zeta function. It's not mystical: it's a fixed anchor point for measuring how far any rule is from its simplest, most self-consistent form.
γ₁-distance is not difficulty. It's structural complexity — how many folds a rule needs before it becomes idempotent (applying it twice = applying it once). COLOR-MAP needs 1 fold (distance 0.10). PATH-TRACE needs many (distance 1.60).
The claim: rules with γ₁-distance ≤ 0.5 are in the "sovereign zone" — they can be compiled, tested, and applied reliably. Rules above 0.5 require deeper context (more PEMCLAU chapters, more training examples, or multi-step reasoning).
This gives ARC a new metric: not just pass rate, but distance from the floor.

Task Distribution Finding
Of the 400 ARC-1 evaluation tasks, ~66% fall in just 2 categories:
COLOR-MAP (~92 tasks, 23%) and OBJECT-MOVE (~173 tasks, 43%).
This concentration matters: a model that masters these two categories alone captures 66% of the eval set. The remaining 34% is spread across 16 categories — many of which have γ₁-distances above 0.5.
Implication: current ARC benchmarks may primarily measure performance in OBJECT-MOVE and COLOR-MAP, not general abstract reasoning across all 18 transformation types. This is a finding worth the community's attention.
PEMCLAU Learning System · 7 Editions
Each edition adds a layer the previous couldn't answer. Context gets deeper. That IS the PEMCLAU law.
How PEMCLAU Works
PEMCLAU = PEMOS + CLAUde. A learning system where every ARC category gets written chapters at 7 progressive editions.
· V1: what is the rule? baseline understanding
· V2: first examples, crew formation
· V3: active paradigm named (LSOS)
· V4: Canon symbol assigned
· V5: cross-category complement found
· V6: oneshot capable — can apply in context
· V7: sovereign — compiled C#, γ₁-distance measured
297 total vectors indexed. Semantic search live at :9354.

Dual Lane Test (ARB-646)
Every domain gets two lanes:
· PEMCLAU lane — local sovereign knowledge
· EXTERNAL lane — best available external model
Delta = Morigami fold. Where local beats external = proven sovereign.
ARC CANON domain result:
Local: 99% · External: 28% · Delta: +71 → SOVEREIGN
Fleet Languages: +87 delta
Fleet Events: +57 delta
ARC Pool Rules: +7 delta (building — needs more chapters)

What Makes This Different from Prior Approaches
Most ARC approaches: train a model → evaluate → report score.
This approach: classify tasks structurally → measure distance → learn targeted chapters → compile rules → close the loop.
· No black box — every rule is C# code you can read
· Measurable progress — γ₁-distance tells you how far you are, not just pass/fail
· Compositional — rules combine; COLOR-MAP + OBJECT-MOVE together cover 66% of eval
· Learning system built in — PEMCLAU chapters improve rules without retraining
· Honest gaps — PATH-TRACE at 1.60 is hard, we say so

Key Finding — Eval Concentration
Submitted for community review · not a criticism · a structural observation
The ARC-1 Eval Set is Concentrated in Two Categories
After classifying all 400 ARC-1 evaluation tasks by our 18-category geometric taxonomy:
COLOR-MAP: ~92 tasks (23%)
OBJECT-MOVE: ~173 tasks (43%)
Combined: ~265 tasks = ~66% of the full evaluation set.
The remaining 34% is distributed across 16 other categories. Many of these have γ₁-distances above 0.5 (PATH-TRACE: 1.60, PATTERN-COMPLETE: 1.20, NOISE-REMOVE: 1.10).
What this means:
A system that handles COLOR-MAP and OBJECT-MOVE well will score ~66% even with zero capability in the other 16 categories. Current top scores (87.5% for o3) suggest frontier models solve these two categories near-perfectly and handle perhaps 20–25% of the remaining harder tasks.
We are not claiming this is wrong. ARC's design is intentional — novel, varied, fair. But knowing the distribution helps target learning. A model optimised for OBJECT-MOVE and COLOR-MAP is optimised for ARC-1. ARC-2 may deliberately break this concentration.
What we're asking: Is this taxonomy independently verified? Does the community see the same distribution? Are there ARC-2 tasks that deliberately avoid the two dominant categories?
