Obstruction Types

module Obstruction;

-- GF(3) trit type
type GF3 := Minus | Ergodic | Plus;

-- Trit arithmetic (mod 3)
add : GF3 -> GF3 -> GF3
add Minus Minus := Plus      -- (-1) + (-1) = +1 (mod 3)
add Minus Ergodic := Minus   -- (-1) + 0 = -1
add Minus Plus := Ergodic    -- (-1) + (+1) = 0
add Ergodic x := x           -- 0 + x = x
add Plus Minus := Ergodic    -- (+1) + (-1) = 0
add Plus Ergodic := Plus     -- (+1) + 0 = +1
add Plus Plus := Minus;      -- (+1) + (+1) = -1 (mod 3)

-- Obstruction from Bumpus decomposition failure
type Obstruction := mkObstruction {
  sexp : ByteArray;          -- S-expression witness
  trit : GF3;                -- Triadic charge
  h1Class : Nat;             -- Cohomology class (>0 = obstruction)
  treewidth : Nat;           -- Exceeded threshold
  color : Word64;            -- Gay.jl deterministic color
  seed : Word64              -- SplitMix64 seed
};

-- Check if decomposition failed
isObstruction : Obstruction -> Bool
isObstruction obs := h1Class obs > 0;

-- VCG externality payment

vcgExternality obs :=
  let baseCost := 1000000    -- 0.001 APT
      multiplier := 10000    -- 100%
  in (h1Class obs) * baseCost * multiplier / 10000;

Intent Types

module Intent;

import Obstruction;

-- Resource type (what can be nullified/committed)
type Resource :=
  | ObstructionRes Obstruction
  | TokenRes Token
  | ReceiptRes ChainId ByteArray;

-- Intent: preference over state transitions
type Intent := mkIntent {
  owner : Address;
  nullify : List Resource;   -- Resources to consume
  commit : List Resource;    -- Resources to produce
  constraints : List Constraint
};

-- Constraint on intent satisfaction
type Constraint :=
  | VcgPayment Nat           -- Minimum VCG payment
  | GF3Balance               -- Sum of trits must be 0 (mod 3)
  | SpectralGap Float;       -- Minimum spectral gap preserved

-- Cross-chain pass intent
passObstruction : Address -> Obstruction -> ChainId -> Intent
passObstruction owner obs target :=
  mkIntent {
    owner := owner;
    nullify := [ObstructionRes obs];
    commit := [ReceiptRes target (hash obs)];
    constraints := [VcgPayment (vcgExternality obs), GF3Balance]
  };

Compilation to Geb

module GebCompile;

import Intent;
import Geb;

-- Compile intent to Geb morphism
compileIntent : Intent -> Geb.Morphism
compileIntent intent :=
  -- Intent = pair of (nullify, commit)
  -- Nullify: inject-left to void (consume)
  -- Commit: inject-right from void (produce)
  Geb.pair
    (compileNullify (nullify intent))
    (compileCommit (commit intent));

-- Compile nullification
compileNullify : List Resource -> Geb.Morphism
compileNullify [] := Geb.terminal Geb.so1
compileNullify (r :: rs) :=
  Geb.pair
    (Geb.injectLeft (compileResource r) Geb.so0)
    (compileNullify rs);

-- Compile commitment
compileCommit : List Resource -> Geb.Morphism
compileCommit [] := Geb.init Geb.so0
compileCommit (r :: rs) :=
  Geb.pair
    (Geb.injectRight Geb.so0 (compileResource r))
    (compileCommit rs);

-- Resource to Geb type
compileResource : Resource -> Geb.Object
compileResource (ObstructionRes obs) :=
  Geb.prod
    (Geb.prod Geb.so1 Geb.so1)   -- (sexp, trit)
    (Geb.prod Geb.so1 Geb.so1);  -- (h1Class, color)
compileResource (TokenRes tok) := Geb.so1;
compileResource (ReceiptRes _ _) := Geb.so1;

Free Monad for Obstruction Game

module ObstructionMonad;

import Obstruction;

-- Functor for obstruction game
type ObstructionF (a : Type) :=
  | NoObstruction a                    -- Decomposition succeeded
  | WithObstruction Obstruction a;     -- Decomposition failed → H¹ ≠ 0

-- Free monad
type Free (f : Type -> Type) (a : Type) :=
  | Pure a
  | Roll (f (Free f a));

-- Obstruction monad = Free ObstructionF
ObstructionMonad : Type -> Type
ObstructionMonad := Free ObstructionF;

-- Attempt decomposition (creates obstruction if tw > threshold)
attemptDecomposition : ByteArray -> Nat -> Word64 -> ObstructionMonad Unit
attemptDecomposition sexp tw seed :=
  if tw <= 3
  then Pure unit
  else 
    let h1 := tw - 3
        trit := toGF3 ((seed `xor` (natToWord64 tw)) `mod` 3)
        color := gayColor seed tw
        obs := mkObstruction sexp trit h1 tw color seed
    in Roll (WithObstruction obs (Pure unit));

-- Bind preserves spectral gap
bind : ObstructionMonad a -> (a -> ObstructionMonad b) -> ObstructionMonad b
bind (Pure a) k := k a
bind (Roll (NoObstruction rest)) k := Roll (NoObstruction (bind rest k))
bind (Roll (WithObstruction obs rest)) k := 
  Roll (WithObstruction obs (bind rest k));

Spectral Gap Tracking

module SpectralMonad;

-- Monad that tracks spectral gap through composition
type SpectralFree (f : Type -> Type) (a : Type) := mkSpectralFree {
  computation : Free f a;
  spectralGap : Float
};

-- Bind propagates minimum gap
bindSpectral : SpectralFree f a -> (a -> SpectralFree f b) -> SpectralFree f b
bindSpectral sf k :=
  let result := bind (computation sf) (\a -> computation (k a))
      newGap := min (spectralGap sf) (gapOf result)
  in mkSpectralFree result newGap;

-- Ramanujan bound for d=3
ramanujanBound : Float
ramanujanBound := 3.0 - 2.0 * sqrt 2.0;  -- ≈ 0.172

-- Check if spectral gap preserved
gapPreserved : SpectralFree f a -> Bool
gapPreserved sf := spectralGap sf >= ramanujanBound;

GF(3) Type-Level Conservation

module GF3Types;

-- Type-level GF(3) for compile-time conservation
type Trit := T_Minus | T_Ergodic | T_Plus;

-- Type-level addition (mod 3)
type family TritAdd (a : Trit) (b : Trit) : Trit where
  TritAdd T_Minus T_Plus := T_Ergodic
  TritAdd T_Plus T_Minus := T_Ergodic
  TritAdd T_Ergodic x := x
  TritAdd x T_Ergodic := x
  TritAdd T_Plus T_Plus := T_Minus
  TritAdd T_Minus T_Minus := T_Plus;

-- Typed resource with trit charge
type TResource (t : Trit) := mkTResource {
  payload : Resource;
  trit : GF3  -- Runtime trit must match type-level
};

-- Balanced transaction: trits sum to 0
type BalancedTx :=
  forall (a b c : Trit).
  TritAdd a (TritAdd b c) == T_Ergodic =>
  Triple (TResource a) (TResource b) (TResource c);

Scientific Skill Interleaving

This skill connects to the K-Dense-AI/claude-scientific-skills ecosystem:

Graph Theory

• networkx [○] via bicomodule
  • Universal graph hub

Bibliography References

• general: 734 citations in bib.duckdb

Cat# Integration

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

GF(3) Naturality

The skill participates in triads satisfying:

(-1) + (0) + (+1) ≡ 0 (mod 3)

This ensures compositional coherence in the Cat# equipment structure.
