README

HabitusX

**The AI Code Outcomes Index.** What happens to AI-written code after it lands.

Millions of public GitHub commits now carry markers from AI coding agents. Existing trackers count them. HabitusX measures what happens next: revert rate, pull request acceptance, review burden and survival, by agent, language and repository, against a human baseline from the same repositories. Continuous, neutral, methodology published.

Repository layout

backend/     Python pipeline, attribution engine, API      see backend/README.md
frontend/    Next.js site (not started; UI phase)
registry/    community-contributable agent detection rules  see registry/README.md
docs/        architecture, methodology, roadmap, ADRs

Status

PR 1 (foundation) delivers the deterministic core: git trailer parsing, revert detection, a data-driven attribution engine, a validated registry of ten agents, and the full quality gate in CI. Data ingestion from GitHub Archive is PR 2. See `docs/roadmap.md`.
