Source verification

• Sourcify: match/exact_match on all 15 contract/chain pairs (implementation + fee collector + factory × 5 chains). Factory on Robinhood Chain holds exact_match (creation + runtime). Repository.
• Blockscout: all three contracts verified on Base (implementation + collector at deploy time, factory propagated from Sourcify ~1h after its 2026-10-05 submission).
• Basescan (Etherscan-family): pending API-key provisioning.
• Full ledger: deployments.json → verificationLedger in the contracts repo.
