What's been built, and what still hasn't

Every project here is participant-submitted, opted into public display, and approved for the showcase. Projects publish an open-source repository and attest to using synthetic or sample data. Showcase approval is editorial, not an operational endorsement; verify the code, license, data, security, and local fit before reuse.

No projects yet. Ten gaps are still open, and there's a working starter for each one.

Submissions close Sunday, August 16 at 23:59 anywhere on Earth. Every track has a fully open-source starter template — a working app, not a skeleton — so the distance between deciding to build and editing real code is a few minutes. A prototype that solves one piece well is a perfectly good submission.
