"summary": "F9C4 gates the idle/default report enqueue. Reset/init loads H'14, each BA26 send reloads H'07, and the FRT2 OCIA handler decrements it; when it reaches zero loc_4046 can enqueue H'00FF if the queue is empty and the FAA5/F9C3 RX gate permits it. With FRT2 OCRA H'7A12 and CKS=phi/32, a phi near 10 MHz gives about 0.7s for H'07, matching the observed heartbeat cadence.",
