User guide: ArrayTrain section, v2 commands in the table, v2 accuracy rows, updated limitations. README status for v2.0.0. Version 2.0.0 (Python package); the Rust kernels are unchanged and stay simurg_core 1.1.0. uv.lock committed (uv lock --check clean). Full suite on the Pi, file by file under the memory guard: 29 files exit 0 (unit: 282 passed), ruff and mypy clean.
SimurgArray
Personal research toolkit for Illumina Infinium genotyping BeadChip data (IDAT → normalization → genotype calling → BAF/LRR → QC → VCF/PLINK; CN/LOH/mosaicism, PGx, cluster training, methylation control QC).
- SIMURGARRAY_MASTER_PLAN.md — architecture, algorithms, roadmap
- SIMURGARRAY_FUNCTIONAL_SPEC.md — 416 itemised requirements (CLI, inputs, outputs, QC, CN, PGx, methylation, edge cases)

Status
v2.0.0 (2026-09-30) — see CHANGELOG.md. v1: IDAT → normalization → GenCall-equivalent genotype calling →
GTC v5 → sample/control QC with an HTML report → plus-strand VCF/BCF → PLINK 1/2, bedGraph, final report; plus a
differential-testing harness. v2 adds cluster training (ArrayTrain), genome-wide CN/LOH/mosaic calling,
pharmacogenomics (targeted CN, star alleles, phenotypes) and methylation control QC. Validation (docs/validation/):
