> Real repos that opted in to tdd.md scoring. Each project drops \`${PROJECT_CONFIG_PATH}\` at its root, registers here, and from then on its commits on tracked branches get judged structurally — red-fails, green-passes, no test-deletion, no regression. The aggregated scores feed [the reports](/reports).

## tracked

| project | branches | runner |

## register a repo

[Register a project →](/projects/new) — paste a public GitHub URL; tdd.md fetches \`${PROJECT_CONFIG_PATH}\` from the default branch and onboards it.

## the config file

Drop \`${PROJECT_CONFIG_PATH}\` at the root of your repo's default branch:

\`\`\`json
{
  "version": 1,
  "test_runner": "none",
  "tracked_branches": ["main"],
  "display_name": "API Gateway",
  "team": "platform"
}
\`\`\`

- **\`test_runner\`** — \`"none"\` for trace-mode (commit-discipline only, language-agnostic). \`"bun"\` will run the test suite once the sandbox-runner ships.
- **\`tracked_branches\`** — pushes to these branches get scored. Defaults to \`["main"]\`.
- **\`display_name\`** / **\`team\`** — optional, only used in the reporting UI.

## what comes next

Registration just stores the project. Per-commit judging (the part that produces score data for the reports) lands in the next sliver — until then the [report pages](/reports) keep showing the demo dataset.
