dx-metrics

Measures AI adoption and its effect on software delivery, computed from git and the GitHub API, framed as DX Core 4.

It answers four questions with numbers a client CTO can defend:

• How much output does one human steer? Commits and merged PRs per distinct steerer, per period. On a team where agents do the committing, this is the headline — it is what a seat buys, and an AI percentage cannot answer it.
• How much of the work was agent-executed? A floor, from Co-Authored-By trailers, labelled as a floor everywhere it appears.
• What happened to delivery? Throughput, cycle time, defect ratio, innovation ratio — before and after each person's first trailer.
• What can this method not see? Declared inline, on every number, every time.

THE ATTRIBUTION MODEL: every commit is a PAIR
