• Call: import fullseye as fs; fs.ledger.raw_demosaic_bilinear(raw, pattern='RGGB') (implementation को सीधे call करना हो तो import gfx2d; gfx2d.raw_demosaic_bilinear(raw, pattern='RGGB'), registry से लेना हो तो opsgfx2d.get("raw_demosaic_bilinear"))
Bayer mosaic → bilinear interpolation से (H, W, 3) RGB, NumPy में।

Red and blue occupy one pixel in four, so a missing value is the mean of the measured neighbours ([[1,2,1],[2,4,2],[1,2,1]]/4 on the masked plane); green occupies two in four ([[0,1,0],[1,4,1],[0,1,0]]/4). The border mirrors the mosaic two pixels out with a non-duplicating reflection, which keeps the 2x2 phase, so a uniform field is exact up to the edge. This is the same estimate the OpenCV bridge cfa_to_rgb makes with cv2.COLOR_Bayer*2RGB, without the 8-bit round trip and without OpenCV.
Ground truth: three affine planes mosaicked and demosaicked come back to 1e-12 away from the border (a bilinear estimate of an affine field is the field). Bilinear is the textbook baseline: it blurs colour edges into zipper artefacts; edge-directed methods are not provided here. Raises ValueError: bad *raw* or *pattern*.
