Motion search → address arithmetic; the sprite footprint re-rasterizes through the Morton cascade at certificate-selected LOD; the same tile substrate serves codec rasterization and shader dispatch (E-H268-REPLAYABLE-TILE-1). Second amortization: the minimal wgpu replay harness this probe needs IS the harness PROBE-GPU-LUT is gated on — build once, both consume. Fisher-z canon applies to the read lanes (helix = the 2z rung). +**Scope guards:** NOT x265 bitstream/byte parity (GOP *grammar* replay on our primitives; x265 itself at most an external bitrate/PSNR reference, never a gate); GPU render-grade only, bit-exactness on the CPU/wasm sprite-state path (C9 discipline). **KILL band:** if object-level helix motion collapses back into a dense per-splat MV field on the test paths, the sprite amortization dies as stated. +**Cross-ref:** ndarray plan `x265-sprite-replay-probe-v1.md` (the spec + pass/KILL bands; §5 probe-queue row added), E-H268-REPLAYABLE-TILE-1, E-FISHERZ-CANONICAL-COSINE-REPLACEMENT-1, helix `ResidueEdge`/`Signed360`, ndarray `splat3d` (EWA + depth_cascade), PROBE-GPU-LUT (shared harness). Execution wave = a next plateau after TD-BGZ-TENSOR-PRE-LANE-REVIEW lands. + ## 2026-07-16 — E-FISHERZ-CANONICAL-COSINE-REPLACEMENT-1 — THE canonical cosine/centroid replacement = the analytic Fisher-z codec (FamilyGamma, no materialization); helix : Fisher-2z :: cosine-replacement : Fisher-z **Status:** OPERATOR RULING (2026-07-16) + FINDING for the grounding identity. No layout changed; the L4 semantics are sharpened, not altered.
