Full Changelog: v0.14.2-pyroscope...v0.14.3-pyroscope
v0.14.3-heap-poisson.1-rc-pyroscope
fix: correct two-layer upscale weight for heap sampling The live-objects profiler had a ~10x undercount because GetUpscaleWeight() only compensated for our secondary Poisson filter (layer 2) while ignoring the CLR's own size-proportional AllocationTick sampling (layer 1). Fix the two bugs together: - ShouldSample() now decrements by the 100KB AllocationTick window instead of objectSize, so the filter operates on the same unit the CLR uses. - GetUpscaleWeight() now computes w_clr × w_ours: the CLR layer weight (allocationWindow/objectSize ≈ 100) times the our-filter layer weight (samplingRate/allocationWindow ≈ 5.5), giving a combined ≈550 instead of the broken ≈512.
