Recurring sprocket (spikonado) errors, by impact

  1. 1KiCadRoutingTools' default --escalation fab took clearance down to 0.175 mm and vias to 0.25 mm, below the board's 0.2 mm and 0.7/0.3 minimums. qfn_fanout laid its built-in 0.45/0.25 via on a 0.7/0.3 board, and the plane finalize step deleted locked port vias.ECAD · Agent failure · 1 report74
  2. 2A kicad-python commit on Nov 8 unpacks the returned item twice, so every create_items() and update_items() call now crashes with AttributeError: type_url. Their scheduled Update KiCad run caught it in a smoke test, and the fix is a local patch they will have to delete once upstream fixes it.ECAD · Agent failure · 1 report66
  3. 3Lessons from a 32 hour power-board run with 101 subagents. Most PCB time went to rediscovering tools, flags and kipy traps; agents re-wrote the same helper scripts about 100 times. ERC passed on a board with an LDO ADJ miswire and back-powering.ECAD · Agent failure · 1 report66
