Models live in cache/models. If that folder is missing from a clone or a shared zip, rendering does not fall back to the part library and import_part reports The part has no model. The only fix was re-importing every part. PR #13 adds a restore command.

- A common USB-C receptacle, LCSC C165948, has pads named A1B12, longer than the 4-character IPC-D-356 field, so export refuses. The Gerbers, drill files, BOM and CPL are fine; only the IPC-D-356 netlist step refuses, and it blocks the whole export. Net names already get aliases, pin names do not.ECAD · impact 66
- The lamina docs check accepts tool names and parameters but not result fields, so naming missing_models in the guide failed CI. Agents read these field names, so the docs should be able to name them. The proposal is a JSON outputSchema per MCP tool.ECAD · impact 66
