prime_field_add_table_reflect

Public research checkpoint, not admitted to Alpha or Stable. Alpha v30 remains 3222 checked-use theorems; Stable remains 432. The on-demand Alpha Lean service does not yet expose these checkpoint theorems; their independently checked literal bundles and unchanged sources are available below.

Every genuine canonical add result occurs at its actual finite table index.

Public research checkpoint: original HA and independently compiled Lean verified; not Alpha-enrolled, no Alpha checked-use authority; not Stable

This checkpoint constructs prime-order fields (k=1), with genuine finite arithmetic tables, cardinality, and characteristic. Inversion is proved only for nonzero elements; the table's zero entry is a zero-to-zero convention. G091 for every prime power p^k, with an irreducible polynomial of degree k, remains open. No extension-field construction or G091 closure is claimed.

∀ p. ∀ B. ∀ C. ∀ a. ∀ b. ∀ v. FpAddPrefix(p,B,C,p · p) → FpAdd(p,a,b,v) → BetaAt(B,C,a · p + b,v)

Every linked abbreviation expands hygienically to the identical original native formula.
