Three repos, what they do and don't. For each repo of the week, the promise and the limit, side by side. It does / It does not. lemmalog. Agent memory that tracks where each fact came from. One node only, memory filled by hand. codex-with-chatgpt. ChatGPT thinks and splits the task, Codex executes. Nothing offline, two paid subscriptions. text-to-cad. A described part becomes a CAD file. No viewer, no multi-part assemblies. Stars can be bought. The one protection that does not depend on your instinct: limit what the module may do.
