Datasets
One generation, frozen and hash-covered.
The public dataset is a single promoted generation. It is immutable: growth happens by appending shards, never by editing one, and the manifest hash covers the result.

Columns
Ten columns. Every one is a property of a prime already in the set — none relates a prime to a number outside it.
| Column | What it holds |
|---|---|
| prime | the prime itself |
| ordinal | its index in the ordered set |
| bit_length | bit length |
| decimal_digits | decimal digit count |
| previous_gap | distance from the preceding prime |
| residue_6 | residue mod 6 |
| residue_30 | residue mod 30 |
| residue_210 | residue mod 210 |
| family_flags | four pair-family bits, set on the larger member |
| wheel30_class | derived wheel class; the reason generation 2 exists |
How this generation was admitted
Generation 2 did not appear by being written. It was proposed against a named base manifest, reviewed independently by two reviewers, and promoted only once the approval threshold was met. Each step is a signed document with its own hash, and the chain is on the governance page.
