    "measurement_notes": "Re-measured 2026-07-18 on Apple M5 Pro 64GB, MTPLX 1.0.4, mtp_history_policy=committed (CLI default), draft_temperature=0.0, enable_thinking=false, warm (4 warmup prompts), 8 measured prompts from calibration_coding suite, max_tokens=192, median tok/s over 3 independent runs. ACCEPTANCE is stable across runs (pos1 0.85-0.87, pos2 0.69-0.71, pos3 0.52) and is the reliable MTP health signal. TOK/S varies run-to-run (AR e2e 35-60) due to thermal/contention variance; speedup ratio inherits this noise. tok_s_e2e = generated_tokens/total_elapsed (wall-clock, includes prefill). tok_s_decode = decode-only (prefill-excluded). multiplier_vs_ar uses e2e. Root cause of the non-vision source (wang-yang) collapse under all policies: its shipped MTP draft head diverges from its own target body (264 of 1803 body leaf tensors differ from this vision variant; MTP head is bit-identical in both). This vision variant's body matches the shipped draft head. The higher-acceptance Shiftedx mxfp4-vision variant (pos3 0.76) requires MTPLX issue #182 / PR #183 to load on stock MTPLX <= 2.1.0."
