kemal a8caa26aa4 P5a: QC — control metrics, thresholds, status, contamination, relatedness, locus summary
- qc/controls: canonical control names (QC-002), bkg/offset (QC-003), 13 genotyping metrics (QC-004/005),
  missing/zero-divisor handling (QC-007/008); controls_raw.tsv / controls_qc.tsv (QC-009/011) incl. compat CSVs
- qc/thresholds + profiles: YAML schema, validation codes, precedence, shipped profiles, auto (QC-020..025)
- qc/status: functional PASS/FAIL/NA, control CLEAR/FLAGGED, flags (QC-030..033)
- qc/contamination: BAF regression; bit-compatible with gtc2vcf BAFregress (36/36, K-017), exact mode too
- qc/relatedness: KING-robust, duplicates, Mendelian errors, pedigree from sheet (IN-018)
- qc/locus_summary: OUT-072, bit-identical to BeadArrayFiles except ChiTest (K-018)
- qc/suggest: suggest-thresholds (QC-026)
- pipeline/qc: disk-backed cohort store; CLI qc controls|samples|contamination|relatedness|loci|suggest-thresholds
- genotype: control tables (OUT-070), het_rate, QC columns, cohort QC
- tests: unit + oracle (BAFregress plugin, BeadArrayFiles locus summary)

# Build bcftools + gtc2vcf plugins (MIT) under refs/tools and generate oracle GTC files from the P0 GSA demo IDATs,
# once per normalization version (GenTrain 3 = normalization 1.2.0, GenTrain 2 = 1.1.2).
# The plugin is compiled with -ffp-contract=off: compilers may otherwise fuse a*b+c into FMA instructions (default
# on aarch64), which changes the last bits of the normalization transforms. Vendor .NET code and NumPy do not fuse.
# Usage: bash scripts/make_oracle_gtcs.sh [chip-folder ...] (default: every chip in the demo set)
