J90 v0.3.3: Nonlinear Evidence Consolidation — Deterministic Mandelbrot–Julia Escape-Time Convergence and Cross-Runtime Verification

J90 v0.3.3 presents a deterministic computational research dataset investigating finite-iteration escape-time convergence, numerical precision, and cross-runtime reproducibility in Mandelbrot and Julia quadratic dynamical systems. The study evaluates two nonlinear model families across three viewport spans (2.0, 1.0, and 0.5) and three iteration budgets (48, 96, and 160), producing 18 deterministic grids of 33 × 25 samples each. An independent Python standard-library implementation verifies the corresponding Node.js computations across 14,850 pixel comparisons. The recorded results demonstrate: Zero Node.js/Python escape-time mismatches across the tested grids. Zero changes to previously observed escape iterations when computational budgets increase. Zero disagreements across 100 exactly matched complex-coordinate pairs at successive zoom scales. Explicit preservation of unresolved finite-budget escape classifications. Deterministic source provenance and SHA-256 evidence integrity. The archived dataset contains the versioned GitHub source distribution, experimental manifest, reproducibility instructions, source-revision lock, research report, derived visualizations, complete SHA-256 checksum manifest, and a Sigstore attestation file. The software implementation is released under Apache License 2.0, while the independently authored dataset, research documentation, and figures are provided for scholarly reuse under Creative Commons Attribution 4.0 International, subject to the respective file-level licensing terms. Scientific limitations: Finite-iteration non-escape does not establish mathematical set membership. Numerical agreement between the tested implementations does not demonstrate universal cross-platform bitwise reproducibility. The experiments do not establish biological life, consciousness, physical emergence, or a universal dimensional-transposition law. J90 is an independent QSOL-IMC research project developed by Trent Slade. Its original conceptual motivation includes public questions raised by Robert Dumont (@Voltardark) concerning orthogonal relationships, interruption observability, and proposed dimensional transposition.
