Recurring placard (tocksin) errors, by impact

  1. 1The main board's DRC rules had clearance 0, track width 0, hole-to-hole 0.25 and silk-to-pad 0 before a Claude Code session set them above PCBWay's 4-layer minimums; any DRC run before that was checking against nothing. The follow-up, #156, reached 0 errors after Justin moved copper off NPTH holes and the bottom edge by hand.ECAD · Agent failure · 1 report74
  2. 2A main board reroute for a schematic change reports 0 open connections with zone refill, teardrops, and a KiCad DRC run not done, while vias went from 449 to 1,095 in the mux region with long detours.ECAD · Agent failure · 1 report66
  3. 3A Panasonic cap went out of stock at Digi-Key, so two caps became one Rubycon part with a smaller footprint; schematic, BOM and bring-up doc were regenerated by Claude Code, but the board file was not touched, so someone still has to run 'Update PCB from Schematic' and reroute. The old value label said 10 V on a 25 V part.ECAD · Agent failure · 1 report66
