Package/pinout/ratings mismatches, SPOF as REVIEW, EMI only with a
datasheet quote, and Tj from copper+vias+θJA when every parameter exists.
Re-extract SI layout_rules from 1.12.0; ImpedenceFinder license stays UNKNOWN.
Each layout_rules SI requirement (diff/SE Z, skew, max length, spacing,
ref plane, vias, layer, return, series R) is one PASS/FAIL/MARGIN finding
with FACT and REQUIREMENT. USB/HDMI/PCIe/ETH/LVDS/DDR only; I2C GPIO CC
and analog REGN are skipped. No invented 90 Ω.
ERROR stays only for RULE+MANDATORY. Hierarchy walks component→pin→net→block.
Derating is PASS/MARGIN/RISK from Vop/Vrated. Timing and PI skip without numbers.
ESD and HS return path are REVIEW, not RULE ERROR.
Layout and AI findings always get action (fallback recommendation). The card
renders that sentence in the body. PCB review context now includes vias under
the footprint, copper thickness, nearby widths, courtyard, and keepout polygons.
FACT, REQUIREMENT, and INFERENCE are separate fields; datasheet provenance
lives in the rule DB so Recommended cannot stay ERROR; LLM output is REVIEW.
Designer decisions persist across rescans. Schematic and PCB share one library
and the same finding object in the report UI.
PCB AI skips a second PDF exam (pintable cache, pdf_path=None) and the report
gains a PCB exam section plus power-trace, thermal, via, Kelvin, and GND-stitch
checks grounded in board geometry and extracted specs.
