superstringCert
plain-language theorem explainer
superstringCert constructs a record that certifies the numerical match between superstring critical dimension 10 and RS dimension 3, yielding exactly seven extra dimensions. A physicist examining dimensional reduction or RS-string unification would cite the certificate to record that 10 - 3 equals the flip-variant count of the three-cube. The definition is a direct structure constructor that supplies three decide lemmas as the record fields.
Claim. The superstring certificate is the structure whose fields assert that the number of extra dimensions equals 7, that this number equals $2^{D} - 1$ where $D$ is the RS spatial dimension, and that $7 = 2^3 - 1$.
background
Recognition Science derives three spatial dimensions from the eight-tick octave (T8). Superstring theory requires a critical dimension of 10, so the difference supplies seven compactified dimensions. The module records that this difference equals the number of flip variants of the three-cube, which is $2^3 - 1$ (MODULE_DOC).
proof idea
The definition builds the SuperstringCert record by direct field assignment: the extra-dimension equality is taken from the decide theorem extra_dim_eq_7, the flip-variant equality from extra_dim_eq_flip_variants, and the numerical identity 7 = 2^3 - 1 from seven_eq_flip_count. No additional tactics or reductions occur.
why it matters
The definition supplies the concrete witness for the RS-superstring dimensional bridge noted in the module opening: D = 3 from T8 meets the string critical dimension 10, with the seven extra dimensions identified as flip variants. It closes the structural observation that 10 - 3 = 7 = 2^D - 1. No downstream theorems yet invoke the certificate, leaving open its use in a larger unification statement.
