Graviton3 c7g.8xlarge, 360 GSE165845 arrays: 360/360 GTCs identical between the Rust kernels and the pure-Python paths; 1 worker 78-80 samples/min (pure Python 29.6). Scaling 1->8 workers efficiency 0.87-0.90; above that the 125 MB/s gp3 disk caps the run (~620 samples/min) and, on a RAM disk, a fixed per-worker start-up cost limits a 360-sample batch to efficiency 0.48 at 32 workers (K-025). Worker state is pickled once. docs/validation/P9.md, result JSONs, guide/README/CHANGELOG updates.

Unreleased (P9)
Optional compiled kernels rust/simurg-core (PyO3): fused GenCall calling and BAF/LRR, libm maps with CPython
semantics, normalization nearest-neighbour searches, BPM parser. Byte-identical outputs to the pure-Python paths
(SIMURG_PURE_PYTHON=1); 78–80 GSA samples/min per Graviton3 core (pure Python 30), manifest loading 4× faster.
Address coverage memoised per IDAT layout; worker state pickled once. bench/profile_genotype.py,
bench/scaling.py. Details and scaling limits: docs/validation/P9.md.
1.0.0 — 2026-09-28
First release: the v1.0 goals of the master plan (§1.1), built and validated phase by phase (P0–P8).
Formats (P1–P2). Readers for IDAT (plain or gzipped; encrypted v1 refused), BPM, CSV manifest, EGT, GTC v3–v5
and sample sheets; simurg inspect; raw X/Y assembly into a canonical Parquet model (simurg ingest, resumable).
Signal and calling (P3–P4). Per-bin affine normalization 1.2.0 and 1.1.2; GenCall-equivalent calling from an
EGT with GenCall score; θ/R, BAF, LRR, LogR deviation, GC10/GC50, intensity percentiles, sex (rules 1 and 2);
GTC v5/v3 writer (simurg genotype). Presets current and autocall-1.6.2.
QC (P5). Control-probe metrics, threshold profiles and YAML, two-axis sample status and flags,
BAF-regression contamination, KING-robust relatedness and Mendel errors, locus summary, threshold suggestion, a
self-contained HTML QC report with xlsx/csv table (simurg qc …).
Outputs (P6). Plus-strand harmonisation with an audit trail; per-sample VCF.gz + tabix or cohort BCF + CSI
(GT:GS:BAF:LRR, optional INFO and intensity fields, merged multi-probe sites, indels from SourceSeq, SNV+indel
merging, auxiliary MNV loci); PLINK 1 .bed and PLINK 2 .pgen; BAF/LRR bedGraph; final report and genotype matrix.
Testing (P7). simurg compare (EXACT/NEAR/DISCREPANCY/UNKNOWN per field and locus class, HTML dashboard) and a
nightly differential run against gtc2vcf, GTCtoVCF and vendor GTCs.
Validation (P8). 360 GSA arrays of 120 1000 Genomes individuals vs NYGC 30x WGS (concordance 0.9934) and GIAB HG001 (0.9985, non-ref F1 0.997); replicate concordance 0.9966. Vendor-equivalence: 2138/2141 Omni2.5 GTCs byte-identical, zero unexplained VCF/PLINK differences vs gtc2vcf, GTCtoVCF and plink2.

Known limitations: needs an existing cluster file (training is v2); no CN/LOH/PGx yet; largest tested cohort 2141 samples; pure NumPy speed.
