Implements a comprehensive DNA analyzer demonstrating RuVector's vector computing capabilities for bioinformatics: Modules (9): - types: Core domain types (DnaSequence, Nucleotide, ProteinSequence, etc.) - kmer: HNSW k-mer indexing with FNV-1a hashing and MinHash sketching - alignment: Smith-Waterman local alignment with CIGAR generation - variant: SNP calling from pileup data with genotype classification - protein: DNA-to-protein translation with contact graph prediction - epigenomics: Horvath clock biological age prediction from CpG methylation - pharma: CYP2D6 star allele calling and metabolizer phenotype prediction - pipeline: DAG-based genomic analysis orchestration - error: Typed error handling across all modules Testing (41 tests, 0 mocks): - 12 k-mer integration tests (encoding, HNSW search, MinHash Jaccard) - 17 pipeline e2e tests (alignment, variant calling, pharmacogenomics) - 12 security tests (buffer overflow, path traversal, concurrency, bounds) Benchmarks: Criterion suite for kmer, alignment, variant, protein, pipeline Binary: 7-stage demo (sequence gen, k-mer search, alignment, variant calling, protein analysis, epigenomics, pharmacogenomics) https://claude.ai/code/session_013B6stXbYwAkWHbE16sjUrq

New RVDNA binary format (.rvdna) purpose-built for AI genomic analysis: - 2-bit nucleotide encoding (4x compression vs ASCII FASTA) - Pre-computed k-mer vectors with int8 quantization for instant HNSW search - Sparse attention matrices in COO format for direct tensor consumption - Variant probability tensors with f16 genotype likelihoods - Zero-copy memory-mappable with 64-byte aligned sections - CRC32 checksums, section-level integrity verification Real human gene sequences from NCBI RefSeq: - HBB (hemoglobin beta, NM_000518.5) - sickle cell gene - TP53 (tumor suppressor, NM_000546.6) - exons 5-8 hotspot - BRCA1 (DNA repair, NM_007294.4) - exon 11 fragment - CYP2D6 (drug metabolism, NM_000106.6) - pharmacogenomic - INS (insulin, NM_000207.3) - preproinsulin Pipeline upgraded to 8 stages using real data: 1. Load 5 real human genes (2,340 bp total) 2. K-mer similarity matrix across gene panel 3. Smith-Waterman alignment on HBB 4. Sickle cell variant detection at HBB codon 6 5. HBB → hemoglobin beta translation (MVHLTPEEKSAVTALWGKVN verified) 6. Horvath epigenetic clock 7. CYP2D6 *4/*10 pharmacogenomics 8. RVDNA format conversion with pre-computed vectors 87 tests, 0 failures. ADR-013 documents the format specification. https://claude.ai/code/session_013B6stXbYwAkWHbE16sjUrq
Complete README rewrite reflecting the final state of the project: - Added "What It Does" section showing actual 8-stage demo output - Added RVDNA AI-native format section with format comparison table - Added real gene data section (HBB, TP53, BRCA1, CYP2D6, INS) - Added actual Criterion benchmark numbers (155ns SNP, 12ms full pipeline) - Fixed Quick Start to match working binary commands - Added collapsible module guides with accurate line counts - Added test suite summary (87 tests, zero mocks) - Added project structure tree with all 13 source files - Added 13 ADR index table - Updated architecture diagram to include RVDNA output stage https://claude.ai/code/session_013B6stXbYwAkWHbE16sjUrq
- Affine gap scoring: 3-matrix Smith-Waterman (H/E/F) with flat 1D arrays for cache-friendly access, direct slice indexing - Indel detection: call_indel() for insertion/deletion from pileup data - VCF output: VCFv4.3 format with proper CHROM/POS/REF/ALT/QUAL columns - CYP2C19 pharmacogenomics: star allele calling (*1/*2/*3/*17), phenotype prediction, drug recommendations (clopidogrel, voriconazole) - Cancer signal detection: methylation entropy + extreme ratio scoring, CancerSignalDetector with configurable risk threshold - Molecular weight: monoisotopic Da for all 20 amino acids - Isoelectric point: Henderson-Hasselbalch bisection with sidechain pKa - K-mer encoding: zero-allocation canonical hashing (hash both strands, take min) eliminates O(n) Vec allocs per sliding window - CRC32: lookup table replaces bit-by-bit (~8x faster header checksums) - Benchmarks: added RVDNA, epigenomics, protein analysis groups 95 tests pass (54 lib + 12 kmer + 17 pipeline + 12 security) https://claude.ai/code/session_013B6stXbYwAkWHbE16sjUrq
Smith-Waterman: rolling 2-row DP replaces 3 full (Q+1)*(R+1) matrices. Only prev+curr rows for H/E, single scalar for F. Memory drops from ~600KB to ~12KB for 100x500bp alignment, fitting L1 cache. Traceback matrix retained (tb==0 encodes stop condition, no full H needed). K-mer encoding: zero-allocation canonical hashing eliminates Vec alloc per k-mer in MinHash::sketch() via dual MurmurHash3 (fwd + rc strands). types.rs to_kmer_vector: rolling polynomial hash computes O(1) per k-mer instead of O(k). Removes leading nucleotide, shifts, adds trailing in constant time using precomputed 5^(k-1). Benchmarks (100bp query x 500bp ref / k=11): kmer/encode_1kb: 4.1µs → 2.3µs (1.78x) kmer/encode_100kb: 364µs → 199µs (1.83x) smith_waterman: 416µs → 386µs (1.08x, 10x less memory) full pipeline: 1.98ms → 1.52ms (1.30x end-to-end) 95 tests pass, zero failures. https://claude.ai/code/session_013B6stXbYwAkWHbE16sjUrq
