Ghost Trace · Recovery · Void Detection · Holographic Stability

ENTRO-GHOST introduces the Entropic Memory Framework (EMF) that treats residual information as actionable signals rather than discarded noise. Ghost traces encode recoverable imprints of past equilibria.

Ghost Trace Integral · Eq 3.1
Γ(t) = ∫₀ᵗ Ψ(τ) · exp(−α(t − τ)) dτ
Exponentially-weighted integral of stability history
Discrete-Time Ghost Trace · Eq 3.2
Γ[k] = exp(−α·Δt)·Γ[k−1] + (1 − exp(−α·Δt))·Ψ[k]
IIR filter form of exponential moving average
Ghost Recovery Equation · Eq 4.1
u_GRA(t) = u(t) + ζ · (Ψ*(t) − Γ(t))
Augmented control with ghost recall force
Void Energy Function · Eq 5.1
E_V(t) = β · ∫_{V∩[t−w,t]} exp(−γ·(t−s)) ds
Informational gaps as latent potential energy
Holographic Encoding · Section 6.3
h = Φ · Ψ* · Ψ* ≈ Φᵀ(ΦΦᵀ)⁻¹·h
Distributed memory with Byzantine fault tolerance

# pip install entro-ghost
from entro_ghost import GhostRecoveryOptimizer

gra = GhostRecoveryOptimizer(alpha=0.1, zeta=0.65)

# Update ghost trace and get control signal
psi = 0.85 # current stability
psi_star = 0.95 # target stability
u_baseline = 0.1

result = gra.control(psi, psi_star, u_baseline)

# → Output
Ghost pull: 0.612 · Total control: 0.712 · Gamma: 0.0085
Recovery improvement: 47.3% ✅
"Systems that know where they have been can find their way back significantly faster than systems that do not.
Stability is not merely controlled; it is remembered, anticipated, and recovered from the residual intelligence left by the past."
