Callable
Immutable, ownerless contract on Base (no operator, no server, no keys). isActive(address account, uint64 minNonce, uint96 minBalance, uint40 maxAgeSeconds) -> bool: true if FactRegistry 0x4a738c86c794e644A919Bbae787830943Bb1A2B6 holds a fact about the account not older than maxAgeSeconds (by block time) meeting the thresholds. Facts are on-chain verified Merkle proofs of account nonce and balance against block hashes (EIP-2935); anyone can submit one via FactRegistry.prove(blockNumber, header, account, accountProof). This is a state-freshness and threshold check, NOT a trust or sybil-resistance signal: the same capital can back many wallets, nonce is cheap on L2.
