#!/usr/bin/env python3 """ PIST Biological Polymorphic Shifter v3.0 — Complete Unified Fix ================================================================ Single-file executable with ALL 14 critical bugs fixed. Combines 28 shifters across synthetic biology, neuroscience, mycology, prions, cellular automata, chaotic maps, Galois fields, and PIST geometry into a unified polymorphic compression framework. Bug fixes applied: B1-B2: Single-file eliminates cross-file import errors B3: Removed self-import in optimizer B4: Length-prefix header replaces 0x00 separator B5: Translation uses unique single-letter AA codes (already safe) B6: Wireworld decode documented as lossy B7: CellularAutomata LUT precomputed at module level (once) B8: Splicing positions use struct.pack (16-bit) B9: Removed dead SHIFTER_CLASSES dict B10: Hachimoji nibble uses modulo instead of min B11: Optimizer passes existing state instead of re-encoding B13: Hachimoji decode uses dict lookup (safe for non-alpha bytes) B14: Huffman decode safe fallback B15: Removed unreachable dead code in beam_search Usage: python3 pist_biological_polymorphic_shifter_v3_complete.py # demo python3 pist_biological_polymorphic_shifter_v3_complete.py --benchmark path/to/file.tsv """ # ═══════════════════════════════════════════════════════════════════════ # IMPORTS (combined from all 4 parts) # ═══════════════════════════════════════════════════════════════════════ import struct import math import json import time import random import sys import hashlib from collections import Counter, defaultdict import heapq from itertools import product, combinations, chain from functools import lru_cache from copy import deepcopy # ═══════════════════════════════════════════════════════════════════════ # CONSTANTS & ALPHABETS (from Part1 + additions) # ═══════════════════════════════════════════════════════════════════════ PHI = 1.618033988749894848204586834365638117720309179805762862135448 # --- Synthetic Biology Alphabets --- HACHIMOJI_ALPHABET = "ACGTUBDHKMVRSWYN" # 16 letters (4 bits) HACHIMOJI_LETTER_TO_VAL = {ord(c): i for i, c in enumerate(HACHIMOJI_ALPHABET)} AEGIS_ALPHABET = "ACGTUBDHKMRSWYVNX" # 18 letters (~4.17 bits) STANDARD_CODON_TABLE = { 'TTT': 'F', 'TTC': 'F', 'TTA': 'L', 'TTG': 'L', 'TCT': 'S', 'TCC': 'S', 'TCA': 'S', 'TCG': 'S', 'TAT': 'Y', 'TAC': 'Y', 'TAA': '*', 'TAG': '*', 'TGT': 'C', 'TGC': 'C', 'TGA': '*', 'TGG': 'W', 'CTT': 'L', 'CTC': 'L', 'CTA': 'L', 'CTG': 'L', 'CCT': 'P', 'CCC': 'P', 'CCA': 'P', 'CCG': 'P', 'CAT': 'H', 'CAC': 'H', 'CAA': 'Q', 'CAG': 'Q', 'CGT': 'R', 'CGC': 'R', 'CGA': 'R', 'CGG': 'R', 'ATT': 'I', 'ATC': 'I', 'ATA': 'I', 'ATG': 'M', 'ACT': 'T', 'ACC': 'T', 'ACA': 'T', 'ACG': 'T', 'AAT': 'N', 'AAC': 'N', 'AAA': 'K', 'AAG': 'K', 'AGT': 'S', 'AGC': 'S', 'AGA': 'R', 'AGG': 'R', 'GTT': 'V', 'GTC': 'V', 'GTA': 'V', 'GTG': 'V', 'GCT': 'A', 'GCC': 'A', 'GCA': 'A', 'GCG': 'A', 'GAT': 'D', 'GAC': 'D', 'GAA': 'E', 'GAG': 'E', 'GGT': 'G', 'GGC': 'G', 'GGA': 'G', 'GGG': 'G', } AMINO_CODONS = {} # reverse map: AA letter -> list of codons for codon, aa in STANDARD_CODON_TABLE.items(): AMINO_CODONS.setdefault(aa, []).append(codon) for aa in AMINO_CODONS: AMINO_CODONS[aa].sort() # deterministic AMINO_ACIDS = sorted(set(STANDARD_CODON_TABLE.values())) # 24 letters BASE_PAIRS = {'A': 'T', 'T': 'A', 'C': 'G', 'G': 'C', 'U': 'A', 'B': 'V', 'D': 'H', 'K': 'M', 'R': 'Y', 'S': 'W', 'W': 'S', 'Y': 'R', 'V': 'B', 'H': 'D', 'N': 'N', 'X': 'X'} # --- Prion HMM Alphabet --- PRION_ALPHABET = "STYCNQKRHDEAVGILMFPW" # 20 amino acids + * PRION_ALPHABET_SIZE = 20 PRION_HMM = { # P(emit | state) -
