Connectivity spot-check (report-only)
- For these GND pads, report whether they have thermal/solid connections to the Bottom GND polygon:
• J24V_IN:GND
• D1 (TVS):GND
• U1 (buck): GND pad
• U2 (3.3 V LDO): GND/EP
• J_SDCARD: shield GND
- If thermal spokes cannot be programmatically detected, state “unable to auto-detect” and just report whether the GND polygon touches those pads.
Targeted DRC (categories only; no edits)
- Run/check these categories and summarize counts:
• Floating/Isolated copper (islands)
• Overlapping fills / polygon overlaps
• Protected intrusions (keep-out violations)
• Clearance violations (global)
- If any violations remain, list each with:
• Category
• Object(s)
• Coordinates or reference
• One-line hint on what to adjust manually
Crystal keep-out confirmation
- Report if any keep-out rules/zones are present around the crystal loop (Y1, C15, C16).
- If present, confirm the Bottom GND polygon is not filling inside that keep-out.
Suggested GND stitching via spots (TEXT-ONLY)
- Suggest 3–6 coordinates or reference-near spots where stitching vias would most help (buck GND loop, TVS/J24V_IN GND, LDO GND/EP, SD shield corners).
- Do not place vias; suggestions only.
