Bumps RP_DEF_MEDIUM_LISTEN_CYCLES 17000 → 15600 so MEDIUM PRI = 161 µs, distinct from SHORT (175 µs) and LONG (167 µs). Three coprime PRIs let the host run 3-PRI Chinese-Remainder unfolding on Doppler aliases beyond the per-sub-frame ±~41 m/s unambiguous range — closes the FPGA half of audit C-5 (PR-F Doppler ambiguity unfolding). Stagger choice (proposal B): SHORT 175 µs — chirp 1 + listen 174 MEDIUM 161 µs — chirp 5 + listen 156 (PR-Q, was 175) LONG 167 µs — chirp 30 + listen 137 In 3 km mode LONG is blind (4500 m blind zone) → SHORT-vs-MEDIUM (Δ=14 µs / 8 %) is the operative pair; in 20 km mode MEDIUM-vs-LONG (Δ=6 µs / 4 %) carries the long-range slice that has SNR for both. Listens picked to differ by ≥5 % so the alias resolver is robust against the 5.1 m/s/bin Doppler quantization. Architecture is unchanged — chirp_scheduler.v already takes per-waveform host_*_listen_cycles. doppler_processor.v / cfar_ca.v are PRI-agnostic and just tag Doppler outputs with sub_frame ID; host-side CRT lives in v7/processing.py (PR-Q.5, follow-on).

No TB default-value asserts touched (tb_system_opcodes / tb_usb_protocol_v2 both use literal 16500 for opcode 0x18 round-trip). Follow-on: PR-Q.2 (cosim T_PRI_MEDIUM align + golden regen), PR-Q.4-7 (v7 GUI 3-PRI CRT unfolder + AMBIGUOUS confidence display), PR-Q.8 (memory close-out).
