Unworld Skill: Replace Time with Derivation

Status: ✅ Production Ready Trit: 0 (ERGODIC - derivational, not temporal) Principle: seed_{n+1} = f(seed_n, color_n) Frame: No external clock, only internal derivation

---

Overview

Unworld replaces temporal succession with derivational succession. There is no "time" - only seed-chaining where each state derives deterministically from the previous.

seed₀ → color₀ → seed₁ → color₁ → seed₂ → ...

The "next" is not temporal but derivational.

Core Formula

# Seed chaining: derive next seed from current seed + color trit
seed_{n+1} = (seed_n ⊕ (trit_n × γ)) × MIX  mod 2⁶⁴

where:
  γ   = 0x9E3779B97F4A7C15  (golden ratio)
  MIX = 0xBF58476D1CE4E5B9  (SplitMix64 multiplier)
  ⊕   = XOR

Why Replace Time?

1. Determinism: Given genesis seed, entire chain is determined
2. Parallelism: Any position computable without computing predecessors
3. Verification: Chain integrity verifiable by re-derivation
4. Frame invariance: No external clock → no observer-dependent ordering

Derivation Chains

1. Color Chain

Single stream of derivations:

Genesis: 0x42D
  → trit=+1 → #D8267F → seed₁
  → trit=0  → #2CD826 → seed₂
  → trit=0  → #4FD826 → seed₃
  → ...

Invariant: GF(3) balanced (sum of trits ≡ 0 mod 3)

2. Triadic Chain

Three interleaved streams from one genesis:

Genesis: 0x42D
  MINUS:   seed₀             → colors...
  ERGODIC: seed₀ ⊕ γ         → colors...
  PLUS:    seed₀ ⊕ (γ << 1)  → colors...

Invariant: GF(3) conserved at each position across all three streams

3. 3-MATCH Chain

Sequence of 3-MATCH gadgets, each deriving from previous:

Match₀: [color_a, color_b, color_c] → combined_trit → seed₁
Match₁: [color_a', color_b', color_c'] → combined_trit' → seed₂
...

Invariant: Each match has GF(3) = 0

4. Involution Chain

Forward and backward derivations that cancel:

Forward:  seed₀ → c₀ → seed₁ → c₁ → ... → seed_n
Backward: seed_n → -c_{n-1} → ... → -c₀ → seed₀'

ι∘ι = id  ⟺  seed₀' = seed₀

Invariant: Involution is self-inverse

5. Best Response Chain

Nash equilibrium via derivational dynamics:

Round 0: agents = {a: t_a, b: t_b, c: t_c}
Round 1: each agent best-responds → new trits
Round 2: ...
Equilibrium: no agent wants to deviate

Invariant: Equilibrium has GF(3) = 0

API

require 'unworld'

# Derive next seed
next_seed = Unworld.chain_seed(current_seed, trit)

# Derive color from seed
color = Unworld.derive_color(seed, index)

# Build full chain
chain = Unworld::ColorChain.new(genesis_seed: 0x42D, length: 12)
unworlded = chain.unworld

# Verify chain integrity
chain.verify_chain  # => true if all derivations correct

Integration with 3-MATCH

The unworld system provides the derivational backbone for 3-MATCH:

# 3-MATCH uses seed chaining for gadget sequence
matches = Unworld::ThreeMatchChain.new(genesis_seed: seed)

# Each match derives from previous
matches.unworld[:matches].each do |m|
  puts "#{m[:colors]} | GF(3): #{m[:gf3]}"
end

Integration with Involution

The involution chain demonstrates ι∘ι = id via derivation:

inv = Unworld::InvolutionChain.new(genesis_seed: seed)

# Forward derivation
inv.unworld[:forward]   # => ["#D8267F", "#2CD826", ...]

# Backward derivation (negated trits)
inv.unworld[:backward]  # => ["#5226D8", "#6AD826", ...]

# Verification
inv.unworld[:involution_verified]  # => true

Mathematical Foundation

Derivation vs Time

Temporal	Derivational
t → t+1	seed_n → seed_{n+1}
Clock tick	Chain step
External	Internal
Observer-dependent	Observer-independent

GF(3) Conservation

At each position in the chain:

trit_minus + trit_ergodic + trit_plus ≡ 0 (mod 3)

This is preserved by the derivation function because:

• Each trit is derived deterministically from seed
• The chain function preserves algebraic structure

Spectral Gap

The derivation chain has spectral gap 1/4 (Ramanujan property):

• Mixing in 4 steps
• Non-backtracking (each seed unique)
• Möbius filtering (μ ≠ 0 for valid chains)
