Theory of Everything Research Programme: TP2 Emergence of Reproduction, Heredity and Darwinian Population — Confirmatory Dataset and Decision Record.

Confirmatory dataset and decision record for the preregistered TP2 experiment in the Theory of Everything Research Programme. TP2 tests whether causal self-maintenance can give rise to autonomous reproduction, parent-specific heredity, heritable variation and multigeneration differential reproduction sufficient to constitute a Darwinian population in a registered artificial computational lineage domain. The study was preregistered on OSF at DOI 10.17605/OSF.IO/FE5P7. The confirmatory programme executed all 40 registered structural-heredity populations and all 40 registered compositional-heredity populations. Across the complete experiment, 800 registered condition-level records were produced. There were no replacement seeds and no technical missing runs. The primary structural results were: HTP2.1 — Endogenous reproduction: 40/40 PASS. HTP2.2 — Parent-specific heredity: 40/40 PASS. HTP2.3 — Heritable fitness coupling: 0/40 FAIL. HTP2.4 — Causal heredity: 34/40 PASS. The no-heredity and parent-shuffled controls produced 0/40 successful bypasses under the preregistered joint lineage criterion. The matched non-maintaining reproducer obtained 14/40 adequately matched controls and was therefore classified MATCHABILITY-LIMITED / INCONCLUSIVE. The heuristic-divider control obtained 0/40 adequately matched controls and was likewise MATCHABILITY-LIMITED / INCONCLUSIVE. The secondary compositional branch produced: HTP2.C1 — Parent-specific compositional heredity: 40/40 PASS. HTP2.C2 — Causal compositional contribution: 40/40 PASS. Under the preregistered decision architecture, failure of any primary hypothesis HTP2.1–HTP2.4 requires TP2 NOT RETAINED. The final confirmatory decision is therefore: TP2 NOT RETAINED. The decisive failure was HTP2.3. Reproductive fitness was prospectively defined as the number of viable direct daughters produced by each parent. In every structural population, this measure failed to generate informative generation-level variation sufficient for non-zero selection covariance and directional response-to-selection analysis. The result is retained as a negative confirmatory finding rather than being reinterpreted post hoc. The evidence supports the emergence of autonomous reproduction, strong parent-specific heredity and causal effects of inherited state within the registered artificial domain. It does not establish the full transition from self-maintenance to a Darwinian population. This dataset includes the complete confirmatory run table, structural and compositional population-level decisions, summary statistics, execution verification and machine-readable final decision record.
