The Fold and the Lens: Vibration, binding, and how a black hole gives matter back

A reproducible, plainly-written physics package that separates established physics from proposal throughout. Established: the Compton mass-size ordering, the nuclear binding curve and iron peak, reversion to hydrogen, a power law explained by standard nuclear physics, and the Riemann explicit-formula mathematics. Proposal (flagged and given falsification channels): a black hole returning some of its matter as hydrogen. Includes reproducible scripts, interactive HTML visualisations, and a companion note on the Riemann-zeros / cavity fingerprint. All numbers reproducible from the bundled code. Disclosure: this work was prepared with AI assistance (Anthropic's Claude) used as a writing, research, and code-checking aid; all ideas, framework, direction, and final decisions are the author's own, and every computational result is reproducible from the bundled scripts.
