 | D6 | C11 | Whether class v3 should favour AMD (fewer, wider loads per hash) at a cost to the 5090's latency-bound share, or accept that AMD cards mine at about a seventh of a 5090 and 4.5x the electricity per hash | Accept it for v3 and say so on the miners page ("NVIDIA first; AMD mines at a lower rate per watt on this class"); open the AMD question as a Counter ASIC 3.0 item with its own measurement | Tonight's rule was the project lead's and the 5090 margin is the anti-chip argument; AMD's position is a public-copy question, not a gate |
 | D7 | C13 | Same as D3's supply wording | with D3 | |
 | D8 | C7 | The miner page says "One click: install, start, the card mines and proves" (site/miner.html 7, 13, 21; site/index.html 484). On HiveOS and the rig installer a rig mines only until a Linux prover build is published, and on the app a 12 GB card mines only, a 16 GB card proves with the miner paused, 20 GB and up does both (the sweep of 5 October, before the v1-shard row) | Qualify the sentence on the miner page and the homepage card: "the card mines; 24 GB cards prove too, 32 GB does both at once; rigs mine until the Linux prover ships". The same page's "a visible 1% software fee you can switch off" becomes "solo mining carries a 1% software fee you can switch off; in a pool the pool's own fee is the only one" once pool-v0 ships (the pool agent fixed the rule: no software dev fee in pool mode) | The sentence is the product's first promise and tonight's measurement bounds it by card |
+| D9 | C3, C15, C26 | No 12 GB NVIDIA card exists in the fleet, so every 12 GB number tonight is scaled from the 5090 and labelled approximate. The 13.9 GB floor is SP1's GPU server code (`docs/analysis/proving-methods.md`, branch proving-methods e7e0db7: builder.rs refuses cards under 20 GB, the trace is allocated at the maximum shard, the CUDA mempool never releases; the proving plan's read of the same file says 24 GB, 4c82e56: the prover-floor agent's rows settle which). The prover-floor patch and the per-card profiles cannot be measured without the hardware | Buy one 12 GB NVIDIA card this week for PC 1's spare slot (an RTX 3060 12 GB or 4070 12 GB, about £250 to £400, approximate; the coordinator's request). Check first whether the RTX 3060 and the RTX 5060 Ti 16 GB that evidence.md row 16 says are "on order" are real and arriving; if so, no purchase, only the delivery date. No public line says "12 GB proves" before a real 12 GB card runs the rebuilt server on the S_p-curve fixtures and recipe | Money, and the one measurement every 12 GB claim rests on; the prover-floor agent's rows tonight replace the approximate figures when they land |
