- gtc-to-vcf --info-fields ASSAY_TYPE,NORM_BIN,GENTRAIN,CLUSTER_SEP,ILMN_STRAND,PROBE_IDS (--egt) and --extra-format X,Y,NORMX,NORMY,THETA,R, in per-sample VCFs and the --merge BCF (OUT-012, plan §8.3); equal to gtc2vcf's values (THETA/R missing where both normalized intensities are 0, K-023) - --merge-snv-indel (OUT-021, EDGE-013): alleles extended to the longest REF; SNV probes read the base at POS - --auxiliary-loci (OUT-035, EDGE-015): rules (a)-(e), E_AUX_INVALID; rule (d) uses the last plus-strand base for minus-strand designs (spec amended, as GTCtoVCF) - export plink --format bed|pgen|both: PLINK 2 fixed-width .pgen/.pvar/.psam; plink2 reads it back to a .bed byte-identical to ours - cohort store keeps raw/normalized intensities for the BCF path; tests (unit + gtc2vcf oracle); docs

Status
Phases P0 (setup), P1 (file parsers), P2 (canonical model, raw X/Y), P3 (normalization) and P4 (genotype
calling, GTC output) are complete — see docs/validation/. Each is validated on 2141 vendor GTCs of the 1000 Genomes Omni2.5 set
(normalization bit-identical; genotypes/scores identical in 2138/2141 samples).
Phase P5 (QC) is complete: control-probe metrics, thresholds/profiles, two-axis status, BAF-regression contamination,
KING-robust relatedness, Mendelian errors, locus summary and a self-contained HTML report (simurg qc report). On 2141
1000 Genomes samples all 717 pedigree parent–offspring pairs are recovered and trio Mendelian error rates are ~0.03 %
(docs/validation/P5.md).
Phase P6 (outputs) is complete: simurg gtc-to-vcf (plus-strand harmonisation with audit, merged multi-probe
sites, per-sample VCF.gz + tabix or a cohort BCF + CSI, optional INFO/intensity fields, SNV+indel merging, MNV
auxiliary loci) and simurg export plink|bedgraph|finalreport|locus-summary (PLINK 1 .bed and PLINK 2 .pgen).
On the GSA demo, genotypes match gtc2vcf and GTCtoVCF with zero unexplained differences and PLINK files match plink2
(docs/validation/P6.md).
