Claims are cheap. Receipts are the interface.
Every entry answers a falsifiable question with a baseline, a method, a measured result, a documented failure, and artifacts you can open. Each one scores itself against six criteria — honestly, which means most do not earn all six.
- ARunnable artifact
- Code, demo, or product you can open and inspect
- BMeaningful baseline
- What happens without the system — measured, not implied
- MMeasured result
- A number that could have come out worse
- RReproducible method
- Steps or harness another engineer can rerun
- FDocumented failure
- Where it still broke, on the record
- EExternal validation
- Someone who is not me depends on it or verified it

A solo Rust tool that installs like a real product
Can one person ship a native developer tool with the full distribution surface — versioned releases, checksums, a Homebrew tap, a landing page — not just a repo?
Where it broke: The tap lagged the source for a stretch — formula at 1.3.1 while the changelog reached 1.6.0 — meaning users could install stale builds.
One persistent signal: the thread survives the route handoff
Can a site's core claim — intelligence survives the handoff — be made structurally true: one visual element that literally never unmounts across navigation?
57 governed tools, 654 tests, one live MCP server
Can one MCP server carry organizational memory, bounded authority, and receipts to every major AI client — and stay up in production?
12 tasks, 7 domains, 3 execution modes — with a human baseline
Does orchestrated multi-agent execution actually beat a single agent — and a human — on real initiative-level work, measured the same way every week?
Eight motion packages, live on public npm
Is the 'token-driven Remotion monorepo' a real, installable system — or a private folder with a nice README?
Config 2021: Figma platformed the community I built
Did the community-through-making thesis — less talk, more people in the file — hold up in front of the industry it came from?
The standard for this page: at least four of six criteria before an entry ships, and the failure field is never empty. External validation is the hardest column to earn — that is what makes it worth tracking.
