Get Accuracy Stats

Model accuracy stats endpoint — hit rates WITHHELD (2026-08-03, P0-4).

Public — no auth required. This endpoint previously served either a synthetic Monte Carlo hit rate (0.891) or, at real_n >= 50, the raw directional hit rate. The 2026-08-03 verification pack proved the raw rate is statistically identical to the market-drift base rate at every horizon — zero information — so no hit rate is published in any form. compute_accuracy_stats() still runs internally (nightly calibration telemetry); only publication is cut. Counters and the timestamp remain so consumers can show tracking progress honestly.
