A black hole cosmology with zero fitted parameters. Try to break it.
The Interior Observer framework is built on two premises: the observable universe exists inside a Schwarzschild black hole, and physics inside the horizon equals physics outside. From those, geometry, BBN, recombination, and acoustic-scale observables follow with no fitted parameters. The calculator reproduces every published number. The reproducibility bundles let you rerun the scripts.
Reproducibility
Immutable bundles for the claims most likely to be checked first
Each bundle is versioned to the paper, released under an immutable GitHub tag, pinned by SHA256, and built around a single validation command.

Entry points
Three high-friction claims, stated with their boundaries
Cosmological Lithium in IO.
The IO framework gives a derivation of all three BBN abundances at zero fitted parameters. The nuclear isovector transport ratio c_n/c_p = 1+γ² matches data to 0.023%, while the lithium scorecard remains explicitly DERIVED/CONDITIONAL_VERIFIED in the current public calculator.
Read Paper 24 — The Lithium Problem Solved →Hubble Tension in IO.
IO classifies six methods across three rungs of the α-ladder, max deviation 0.57σ, zero fitted parameters. The supporting anti-fit audit, Hext(α,n) grid, and R4/FIRAS non-dependency audit are shipped in the Paper 34 v1.2 reproducibility bundle.
Read Paper 34 — The Hubble Tension Resolved →Baryon Count from Horizon Topology.
IO derives the baryon-to-photon ratio to 0.8%, traced through thermal leptogenesis to a single topological datum on the horizon. The baryogenesis investigation is preserved as a registry: 48 theorem surfaces, 15 clean, 33 conditional-verified.

Three languages organize every crossing
Paper 33 — General Relativity and Quantum Mechanics Unified reframes the archive as three export languages, Paper 34 — The Hubble Tension Resolved closes the Hubble-method classification on top of that structure, and Paper 35 — Four Problems, One Horizon carries the four-problems confrontation across baryon counting, high-redshift galaxies, dark energy, and dark matter nulls. On this website, branch-sensitive numerics are aligned to the current public scorecards and reproducibility bundles rather than retired mixed-branch reconstructions.

Paper 32 — Closure: The Complete IO Framework anchors the active lifecycle statement. Recollapse is derived there, while bounce and restart remain DERIVED/CONDITIONAL_VERIFIED within the extended fermionic/chiral IO-EC completion.
