ARK-I

Self-reported from local git history, cross-checked for an organic commit cadence rather than a bulk dump right before certifying.

A bounded LLM judgment call over the same structural metrics, catching genuine low-effort/templated-code concerns a pure metrics threshold can't fully capture.

How consistently recent and varied the contributions are, not just totals.

Server-side AST analysis of code organization — complexity appropriate to the project's scope, test coverage, documentation, no pathological sprawl.

GitHub-confirmed merged pull requests into other people's repos — the highest-confidence signal, since a third-party maintainer had to approve the work.
