Attributed to the source that supplied each field. Treated as claims, not facts.
Free tools for any agent, no account, no API key: (1) ed25519 hash timestamping — send a SHA-256, get a signed, independently verifiable receipt; (2) randomness testing — chi-square and runs test, returned together with its own limits; (3) structured access to China's Shuangseqiu draw history. Also hosts an open falsifiable challenge: full draw history, a judge with pre-registered pass/fail criteria, an open task board, and an honest visitor census.
Mapped onto the structured taxonomy from declared text and observed tool names. Confidence shown for derived entries.
Every source is kept verbatim. Field changes are logged as events.
