Whole-claim cubic examination

../

derivations: Independent derivations testing equality transport, the small-parameter singular estimates, and the interval enclosure argument for the frozen cubic assertion.

report: Whole-statement adversarial examination of the frozen cubic lemniscate bound and equality classification, with explicit source boundaries and failed diagnostic limitations.

reproduction: Exact inputs, execution substitutions, rerun commands, and the successful and failed computation outcomes for the frozen cubic examination.

Read the report, independent derivations and reproduction account. The distinct grade controls their accepted weight. The full checker is a uniform enclosure proof, not a parameter sample. The auxiliary diagnostic remains an exit-1 program with four failed exact-endpoint predicates; the grade gives those predicates no successful-calibration weight.

Editorial filing replaces the copyrighted Eremenko–Hayman excerpt by a bibliographic locator and adjusts the source-table and reproduction descriptions accordingly. The enclosing report path and reproduction commands include the review/ directory. No theorem, proof deduction, checker, diagnostic, mathematical input, verdict or source-reading qualification is changed.
