graph-grafting

Trit: 0 (ERGODIC - Coordinator) GF(3) Triad: queryable (-1) ⊗ graftable (0) ⊗ derangeable (+1) = 0

Overview

Combinatorial complex operations replacing GraphQL with pure graph theory:

| Operation | Trit | Description | |-----------|------|-------------| | Queryable | -1 | Tree-shape decision via bag decomposition | | Colorable | 0 | GF(3) 3-coloring via sheaf | | Derangeable | +1 | Permutations with no fixed points | | Graftable | 0 | Attach rooted tree at vertex |

Mathematical Foundation

Grafting = attaching a rooted tree T at vertex v of graph G:

Graft(T, v, G) → G' where:
  - V(G') = V(G) ∪ V(T)
  - E(G') = E(G) ∪ E(T) ∪ {(v, root(T))}
  - Adhesion = shared labels at attachment point

Usage

using .GraphGrafting

c = GraftComplex(UInt64(1069))

# Build PR tree
root = GraftNode(:pr18, Int8(0), :golden, 0)
alice = GraftNode(:alice, Int8(-1), :baseline, 1)
bob = GraftNode(:bob, Int8(1), :original, 1)

# Graft nodes
graft!(c, root, :none, String[])
graft!(c, alice, :pr18, ["aptos-wallet-mcp"])
graft!(c, bob, :pr18, ["aptos-wallet-mcp"])

# Operations
tree_shape(c)           # Queryable
trit_partition(c)       # Colorable  
derange!(c)             # Derangeable
compose(c1, c2, :vertex) # Graftable

# Verify
verify_gf3(c)  # → (conserved=true, sum=0)

Connection Pattern

Combinators compose operations. This skill provides composable abstractions.

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.
