From 627db2eba6df45cae83129aa246d0e4e7be20270 Mon Sep 17 00:00:00 2001
From: Michele Bigi
Date: Wed, 23 Sep 2026 06:30:28 +0200
Subject: [PATCH] USB/RMII cert lines and not_reviewed count fix (2.85.0).
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
USB D+/D− is one English certified/not-certified line vs the packed 90 Ω
cite. RMII ETH_RXD/TXD/TXEN is identified as PHY–MAC, not RJ45 100 Ω.
J2 missing-field L1/L2/L3 noise is silent. PCB AI failures go to
review_errors; not_reviewed count matches one designator per row.

What's new in Periscope.
+## 2.85.0 — 2026-09-23 — USB / RMII cert lines; not_reviewed count
+
+USB 2.0 D+/D− is one line: calculated pair Z versus the packed 90 Ω board cite. Certified names the measured ohm and the cite. Not certified says why — Z is outside that cite, or Z cannot be calculated from the PCB stackup/geometry. Missing length, stub, via, termination, rise/fall, and channel fields do not each warn. L3 is omitted when no channel fact is on file.
+
+LAN8720A ETH_RXD / ETH_TXD / ETH_TXEN are RMII (single-ended PHY–MAC), not RJ45/MDI 100 Ω. One line: `RMII certified — …`. No Italian «mancanza di tr, f» on those nets. RJ45 pairs keep `Ethernet certified / not certified`.
+
+`not_reviewed` count matches the list (one designator per row). Real PCB AI failures go to `review_errors` with the exception message — not a blanket `pcb_review error` on every skip. ICs already in coverage are not listed as not-reviewed.
+
+- [Changed] `protocol_l1.py`, `protocol_l2.py`, `protocol_l3.py`, `protocol_report.py`, `af_trace_check.py`, `si_check.py`.
+- [Changed] `pcb_validation.py`, `pcb_pipeline.py`, `pcb_checks.py` merge; report UI copy.
+- [Changed] Protocol tree shows the certification sentence.
+- [Changed] pytest `tests/pcb/test_j2_usb_cert_line.py`, `test_rmii_cert_line.py`, `test_not_reviewed_count.py`.
+
## 2.84.0 — 2026-09-22 — Exposed-pad names, ESD cites, CC-via-net, Ethernet pair Z
PE-BOM-011 treats EP, EPAD, THERMAL PAD, exposed pad, and the footprint's exposed land (including pin_count+1) as the same pad when both sides have one. A datasheet exposed pad with no land on the footprint stays ERROR.
