- signal/normalization/numerics.py: vendor percentile, trimmean, MAD sigma (old/new), bisquare robust fits, float32/float64 typing and sequential sums reproduced exactly (ported from gtc2vcf, MIT) - signal/normalization/fit.py: outlier removal, offset, rotation, shear, scale, nn12/rr12, single-channel model for small Infinium I bins, exact and binned nearest-neighbour sweeps; vendor quirks marked QUIRK - signal/normalization/apply.py: affine transform and theta/R - pipeline/normalize.py + CLI `simurg normalize` - oracle GTCs rebuilt with -ffp-contract=off (aarch64 gcc fuses a*b+c by default, shifting the last bits); the old FMA oracle differed by <=4 ULP Result: transforms bit-identical to the oracle for all 36 GSA samples x 48 bins, for both normalization versions (3456/3456 bins, 0 ULP).

# 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)
