  description: Dual-chain trust anchor. Chain 1 (CopyrightChains): CopyrightID 0xfd1cecff3392e727c00c7d5c44a296e2f37befc1140f744ba4dffbd145d44e98. Chain 2 (Bitcoin): anchored in block 953528 (2026-06-13T15:41:10Z), registered by our registry partner. Bridge: the canonical record at https://artists.proofprofile.net/proofs/track/5AF2wcOGWK4zWs56ALqXv2.json contains the same CopyrightID — hash it and compare to OTSHash, then confirm the Bitcoin block independently via OTSBitcoinBlockVerifyURL or https://artists.proofprofile.net/api/v1/bot/ots/verify/track/5AF2wcOGWK4zWs56ALqXv2.
