Emberthread’s dead-seam detector

Field notes

The homepage frames its central diagnosis around a repository that had 1,308 passing tests while 229 files were reachable only from tests. Seamcheck is presented as a command-line scan that reads entry points and follows the import graph, with an MCP-server version intended for agent-operated checks. The accompanying manual is organized into nine chapters and includes a receipts appendix mapping load-bearing numbers to evidence. The page also offers clean HTML and a markdown edition for the complete $19 book.
