Fork counts can fall when forks are deleted or cleaned up on GitHub's side, so negative growth here is data rather than an error.

No rank crossover with another tracked tool in the last 90 days.

Current readings are one GitHub REST API call against /repos/ai-christianson/RA.Aid, each with its own provenance page (see the table above).

Growth figures are reconstructed from dated Wayback Machine captures of the repository page — a fact about a past date that no single API call returns. They are never interpolated, each row names the capture it used, and the whole series is downloadable as CSV or JSON with its method and limits attached.

Reconstructed and measured figures are kept separate and never averaged. See methodology.
