The Factoring Claims RegisterSuccessor to the RSA Factoring Challenge (1991-2007)
The normalized claim census
Seventy-seven factoring and RSA-break claims, graded by the evidence for the claim, not by who made it. At the advertised level of a general cryptographic-size RSA break, 0 are substantiated and 0 actually broke RSA.
The register keeps the 54-number RSA catalogue beside all 77 normalized claim records. Historical entries say only what the locked local record says. Live entries keep C1 instance evidence separate from C2 general speed, C3 classical complexity, and C4 quantum-resource claims.
One-multiplication self-adjudication applies to instance claims only and never promotes a generality verdict.
Four local watchers are configured. A quiet watcher is shown as quiet; a failed check is never shown as success.
Four watchers configured; no factoring-corpus check is recorded yet. Each is shown as quiet, not successful.

RSA-250 is the largest general-purpose factorization in the locked catalogue: 250 decimal digits, 829 bits, recorded on 28 February 2020. That is a record for one number, not a verdict that general RSA factoring is easy.
Seed records stay in the locked JSONL files. Later factoring-corpus events appear from the append-only journal.
No factoring-corpus journal events are recorded in the local append-only journal.
Before filing a factoring or RSA-break claim, run the four class-aware checks. They ask for the factor witness, complete resource accounting, a fresh target, and an honest statement of quantum actuality.
