A Software Contribution Atlas of 173 Candidate Records

Rapid software development with coding assistants can leave a large collection of repositories, prototypes, deployment notes and design conversations without a reliable account of what each contributor supplied. This paper presents a retrospective evidence catalogue of 173 candidate records from an author-maintained software portfolio. The records were originally assembled in a contribution review dated 4 to 5 October 2026 and are reorganized here into 20 technical families. The catalogue preserves records whose earlier commercial screening was unfavorable, marks third-party mechanisms as upstream context, and retains uncertainty about conception rather than assigning every feature to the repository owner. Imported attribution assessments comprise 55 records in which the earlier review reported user statements of essential steps, 44 in which it attributed mechanism design to an assistant, 51 with insufficient conception evidence, and 23 centered on third-party work. These are historical assessments rather than independently adjudicated authorship findings. A separate public repository discovery snapshot contains 770 entries on 20 October 2026. Repository counts are not contribution counts. The release supplies a complete record-to-family map, 11 explicit overlap leads, public navigation links, and a verification script for structural counts. It reports a catalogue and a research agenda, not 173 new inventions or experimentally validated systems. The main contribution is an inspectable organization of evidence and attribution boundaries that supports subsequent, topic-specific software studies. The expanded release additionally preserves 59 project and archive source accounts with explicit overlap and evidence boundaries. It includes substantive technical appendices for all 173 historical records and the additional accounts. The inventory is not a count of independent papers, and its publication does not complete the separate topic-paper programme. Preparation of this report was assisted by Codex. The research programme is directed toward human agency, financial inclusion, and evidence-based accountability.
