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.
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.
Documents a parallel MODE=pcb exam job (inventory + datasheet-gated
checks) that reuses placement_check, si_check, and the placement job
pattern. Parks F2 packing/export.
