Prime-field arithmetic and finite tables

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.

Construct the actual operations on representatives below a prime, complete beta-coded tables, a finite enumeration, and addition-of-one histories proving exact characteristic.
