Method

Three rules.

202 source records support 88 projects and series. Related records remain searchable without being counted twice.

  1. 01

    Count each project once

    Recordings, translations, mirrors, profiles, excerpts, and source pages do not inflate the total.

  2. 02

    Separate contribution from causality

    Individual contribution, program reach, supported pipeline, and organization outcomes remain separate.

  3. 03

    Keep the limit beside the claim

    Each derived measure keeps its period, source, attribution, rounding, and caveat.

Owner-reviewed contributions

Owner-reviewed entries describe curricula or internal tooling whose materials are not public; they are not independently inspectable source code. Status distinguishes developed material, merged implementation, and delivered work. Private records and repository links stay private.
