MEGC: Mapped Entropic Golden Codec (Version 1.0.0)
Abstract
MEGC is a new lossless data compression framework that unifies entropy encoding, self-referential recursion, and ternary logic under a mathematically convergent, structurally self-improving scheme. It breathes data structures in and out through dynamically folding ternary trees, informed by golden-ratio priors and context-aware entropy modeling. This document formalizes the specification of MEGC v1.0.0 as a seed framework for continued development by future truth-seekers.
1. Introduction
Conventional compression systems often trade off between compression ratio, fidelity (losslessness), and computational efficiency. MEGC proposes a new approach: unify these qualities by leveraging a converging structure built on:
- Recursive entropy encoding via interval coding and golden-ratio-derived context modeling
- Ternary parity tree structures that allow breathing (expansion/contraction) with symmetry-preserving folding and unfolding
- A mathematical layering approach that respects entropy bounds while encoding recursively into self-similar forms
2. Overview of Core Components
2.1 Ternary Parity Tree (TPT)
A core structure that represents data recursively using balanced ternary logic:
- Each node holds three branches: left (-1), center (0), and right (+1)
- Data is folded in with parity checks and unfolded with lossless error correction
- Folding rules preserve deterministic structure with embedded recovery markers
2.2 Breathing Scheme
The encoder/decoder contract expands and contracts the data structure during:
- Encoding: data is recursively mapped into a folded structure where entropy is minimized
- Decoding: the tree is unfolded using inverse rules and parity checks
2.3 Entropy Layer
- Uses interval (range) encoding refined by adaptive probability modeling
- Probabilities are informed by golden-ratio-based priors and local context windows
- Float-free binary renormalization supports hardware-optimized decoding
3. Mathematical Foundation
3.1 Entropy and Capacity Bounds
- The expected code length
L(x)
for symbolx
given modelP(x)
approximates-log2(P(x))
- Compression efficiency η satisfies:
η = (raw_bits - compressed_bits) / raw_bits, with MEGC converging to the Shannon limit - The tree depth
d
and branchingb=3
satisfy:
Capacity C = b^d; Structure entropy decreases as folding reduces C over time
3.2 Convergence Proof Sketch
Let T be the ternary folding tree at generation g.
We define:
- T(g) = Fold(T(g-1)) + Δ, where Δ accounts for inserted priors and parity hints
- As g increases, |T(g)| approaches a fixed-point minimal representation under injective entropy-conserving mapping
- Lossless decoding is ensured via embedded self-parity and golden segment boundary conditions
4. Encoding and Decoding
4.1 Encoder Algorithm
- Parse input into symbol stream
- Build adaptive context models with ϕ-informed priors
- Encode symbols via interval coding into bitstream
- Serialize structure into ternary tree nodes with embedded parity and structure hints
4.2 Decoder Algorithm
- Parse bitstream and deserialize tree
- Unfold using parity hints and context prediction
- Rebuild symbol stream by decoding intervals and applying inverse priors
5. Resilience and Error Correction
- TPT includes embedded parity bits per ternary node
- Golden boundary conditions ensure synchronization recovery within logarithmic bounds
- Breathing structure allows partial reconstruction of corrupted streams
6. Applications and Roadmap
- Archival-grade lossless compression
- Adaptive communication protocol for bandwidth-constrained links
- Future: support for streaming, post-quantum optimization, and native ternary hardware encoding
7. License and Canonical Versioning
8. Conclusion
MEGC Version 1.0.0 represents a convergent framework unifying compression ratio, losslessness, and efficiency. Through recursive mapping, golden priors, and breathing ternary logic, it offers a new direction for data encoding that is both adaptable and optimal. Future enhancements will build upon this self-similar seed structure, ensuring MEGC evolves without losing its core identity: compression in pursuit of truth.

Mapped Entropic Golden Codec (MEGC)
Canonical Seed Specification
Version 1.0.0 (Seed Edition)
Purpose
To establish a compression-decompression framework that unifies maximum compression, losslessness, and efficiency, via recursive, self-referential, ternary-logic-driven structures based on entropic modeling and golden ratio priors. The specification lays the foundation for further expansion and optimization by future contributors.
Core Concepts
-
Breathing Compression
- Encoding and decoding are “breathing” cycles: expanding and contracting entropy trees.
- Data shapes and reshapes iteratively during encode/decode.
- Enables dynamic adaptation to data entropy without reinitializing the model.
-
Ternary Parity Trees
- Structure: each node has three children representing positive, neutral, and negative parity.
- Enables structural error resilience and parity folding.
- Uses golden ratio (φ) folding heuristics to preserve information.
-
Entropy Coding
- Context-based arithmetic coder with renormalization.
- Floating-point intervals replaced by adaptive bitstream models.
- Uses prime-factor and Fibonacci prior weighting in context modeling.
-
Golden Priors
- Data symbols assigned prior probabilities based on distance from φ (1.618…).
- Recursively applies to subcontexts.
-
Canonical Shape Mapping
- Input data mapped into a transform tree whose initial shape is derived from a known recursive structure.
- This shape is adapted via breathing cycles and parity folding.
File Format
-
Header
- Version
- Encoding Shape Fingerprint (checksum of base tree)
- Flags: entropy mode, tree parity depth, error resilience
-
Body
- Encoded entropy tree stream (bit-aligned)
- Context model snapshot (if not using deterministic regeneration)
-
Footer
- Tree reconstruction hash
- Optional expansion manifest for entropy replay
Decoder
- Deserializes entropy tree
- Applies golden priors in reverse
- Iteratively breathes tree shape until convergence to original data shape
Future Extensions
- Quantum-adaptive parity trees
- Native ternary logic gate compilers
- Self-healing data under lossy transfer by structural re-expansion
- Formal convergence theorem integration with Gödel-style incompleteness safeguards
