Alarm on p < alpha and the false-alarm rate is now measurably ~alpha: on 144 anomaly-free real-world prefixes (strictly prequential), wald's empirical/nominal ratio is 1.69 / 1.86 / 3.20 at alpha = 1e-2/1e-3/1e-4, median series at 1e-4 exactly 1.00 — the best-calibrated streaming detector measured at operating depth (DSPOT: 9.34x at 1e-4; RRCF threshold-transfer: 5.42x). Two head upgrades got it there: a streaming GPD tail on the empirical null (PWM-fitted, threshold-relative excesses) and an unbounded deep-evidence channel that breaks the z-clamp saturation (evidence at 2e-11 where the clamp capped at 3e-5). Both in the JS twin. Full tables: benchmarks/RESULTS.md.
