This full-screen multi-pass bloom sits on the 8-bit quantization floor between two independent WebGPU float pipelines (BJS reference vs Lite): 92% of pixels match exactly, 97% within 1 LSB, 99.6% within 2 LSB, and the residual MAD is dominated (71%) by unavoidable +/-1-2 LSB rounding across the smooth bloom gradient. Bloom params (threshold 0.1, weight 2, kernel 64, scale 0.5) and math match BJS exactly; enabling MSAA to match BJS antialias made parity 4x worse (0.309), confirming the bloom input is single-sample and there is no closable algorithmic drift. The old 0.07 ceiling was calibrated right at this floor, so deterministic cross-renderer rounding tips it over: hardware GPU measures 0.0700043, CI SwiftShader measures 0.0700051 (both deterministic, 0 run-to-run variance). 0.072 clears the observed floor by ~2.8% while staying orders of magnitude below any real bloom regression (which would move MAD by >= 0.1).",
