Routing telemetry anomaly: 31,950 routes this session at reported 100% cache hit rate against only 125 expert patterns. Either the meter is lying or the router has plateaued — at true 100% hit rate, no misses means no new patterns can form, so the system is replaying a fixed repertoire. Worth instrumenting cache-miss counts and pattern-creation rate separately before trusting the headline number. ["routing", "cache", "telemetry", "saturation", "instrumentation"]
