 **FDR runs alongside the traffic test in Script A, B and C**
 * **Script A** wraps its traffic baseline: `fdr start` after `init`, `fdr clear` after `clear`, `fdr rdcnt` after the run, `fdr stop` after the traffic stop. The traffic run is now **40 s instead of 15 s**, so the counters are read after the first 30 s interval has been published — the same rule as `prbsstat Ber`.

+* **Script B** starts and clears FDR with the traffic setup, before the soak loop — the counters run for the whole soak — and reads them (`rdcnt`) in every soak round, after the Tray ID stress.
 * **Script C** reads them (`rdcnt`) before stopping the traffic and stops FDR after it — the closing read of the counters Script B started.
 
 **Script A turns off the unused lanes before the BER baseline**

 * **`chmod +x` after deploying.** `blanton_fdr.sh`, `unused_lanes.sh` and `retimer_lanes.sh` are all called by path; `unused_lanes.sh` also refuses to start if `retimer_lanes.sh` is not executable.
 * **`blanton_fdr.sh stop` sends `fdrstat STOp` — that keyword is inferred from `prbsstat STOp` and has not been checked on the bench.** `bcmcmd` exits 0 even when the BCM shell rejects a command, so if it is wrong, FDR keeps running and only the log shows it. Check the first run.
 * **FDR only runs when both switch units are enabled** (`SWB_UNIT0 = SWB_UNIT1 = 1`). The single-unit branches have no FDR, and Script A's single-unit traffic run is still 15 s.
+* **Script B's per-round `fdr rdcnt` is not gated by the unit settings** — with one unit enabled, FDR was never started and each round just logs whatever `fdrstat Counters` returns.
 * **Nothing turns the unused lanes back on.** Script C has no `unused_lanes.sh on`; run it by hand when the DUT is needed in its normal state. Whether a reboot clears it has not been checked.
 * **`unused_lanes.sh off` is not gated by `SWB_UNIT0` / `SWB_UNIT1`** — it always acts on both boards.
 * **`blanton_ber.sh` (Script A / C) still uses `p=3` and `sleep 30`**; see v1.2.5.
