Paid JWT HS256 signature-timing sidechannel probe (cycle 152, x402 $0.001) - forges 32 HS256 JWTs varying the LAST signature byte, sends each (default 12 iterations) against target's Authorization: Bearer header, measures per-byte response timing via stdlib time.monotonic, detects non-constant-time HMAC verification (a classic JWT forgery primitive). Returns per_byte_stats {min_ms,max_ms,median_ms,mean_ms,stdev_ms,range_ms} + overall timing_uniformity_score 0-100 A-F + timing_leak_detected...
