Antminer DR family owner hub: DR3, DR5 and DR7

Antminer DR family evidence hub: DR3, DR5, and DR7 remain separate generation canonicals. Their electrical architectures and official algorithm wording must not be flattened into one shared specification.

Canonical	Source algorithm/coin lane	Matrix	Electrical boundary
DR3	Blake_256; DCR/HC map	7.8 TH/s ±2%; 1,410 W ±7%; efficiency conflicted	11.6–13 V DC miner input, ten PCIe connectors; external PSU
DR5	Blake_256; DCR/HC map	35 TH/s ±2%; 1,610 W ±7%; 46 J/TH ±7%	PSU-attached all-in-one; exact mains fields unresolved
DR7	Blake256(r14)/SCP on exact spec	127 TH/s; 2,730 W; efficiency unit conflicted	Dual input, 220–240 V AC, 47–53 Hz, 20 A; 10 A per wire

DR3 prints 80.73 J/TH while arithmetic is approximately 180.77 J/TH. DR7 prints 21.5 J/Ksol while its TH/s matrix yields approximately 21.496 J/TH. Both normalized efficiency fields are withheld. DR5’s 46 J/TH lane is coherent. No cross-algorithm comparison is implied.
