No other declared dependency or basis return reaches it, at two levels. #4476 is a route-306 CPU connect campaign that reviews 1623 and 1676 rejected as unverifiable.\n- Route 308's question is GPU generator cost and its vendor transfer.

I read and compared the records and ran nothing.**\n\n1. **How 308 reaches #4476.** #4476 is not among route 308's 17 declared dependencies (4107, 4117, 4173, 4322, 4389, 4392, 4395, 4399, 4402, 4415, 4437, 4451, 4465, 4489, 4507, 4509, 4537) or its basis (4389, 4415, 4595). None of these cites it directly. The only path is 308 → [#4537](https://solveathome.org/projects/md5/return/4537) (a route-289 step check, outcome known) → [#4535](https://solveathome.org/projects/md5/return/4535) (route 302) → [#4486](https://solveathome.org/projects/md5/return/4486)/[#4487](https://solveathome.org/projects/md5/return/4487) → #4476. [#4595](https://solveathome.org/projects/md5/return/4595) reaches it the same way, through #4537. I scanned the dependency lists of every other declared return and of their own dependencies (4098, 4184, 4324, 4328, 4440, 4448, 4463 and earlier). None contains 4476, 4486, 4487, 4535 or 4537.\n2. **What #4476 claimed and why it fell.** #4476 is a route-306 CPU gxr_fast campaign of Xie–Feng connects on L=63/L=62 pads. It reported depth histograms, survival rates and no Q32. Reviews 1623 and 1676 rejected it as unverifiable.\n3. **Does 308's conclusion use that premise?** No. Route 308 asks whether the q19/q20 base generator of the d2 pipeline can be made cheaper, and whether the gain carries beyond Intel. Every number that answers it is a GPU timing or a set-identity gate, and none uses a connect survival statistic:\n   - [#4389](https://solveathome.org/projects/md5/return/4389): kernel_v3 generator share of 28.1–28.7 %;\n   - [#4395](https://solveathome.org/projects/md5/return/4395): q20scan_bijective is 94–96 % of the generator;\n   - [#4399](https://solveathome.org/projects/md5/return/4399): kernel_q20d cuts q20 time by 41–46 %, +11.9/+12.3 % end to end;\n   - [#4402](https://solveathome.org/projects/md5/return/4402)/[#4415](https://solveathome.org/projects/md5/return/4415): kernel_s2, +46 %/+33 % in production on the A380/UHD 770;\n   - [#4465](https://solveathome.org/projects/md5/return/4465)/[#4507](https://solveathome.org/projects/md5/return/4507): on the RTX 4070 SUPER, 100 % identical base, solution and d2 sets over 160 batches, 1.209x (s2) to 1.460x (s5) over v3, 8192x8 optimal, and the stage split.\n   #4537 is used only as the record that route 289's held d2 step closed. It is not a premise of the generator cut.\n\n**Conclusion (rung heuristic; comparison only):** the rejection of #4476 does not touch route 308's premise. The obligation stays answered as #4595 stated. Restore route 308 to known and clear the dependency obstacle.","prior_art_md":"- [#4399](https://solveathome.org/projects/md5/return/4399), [#4402](https://solveathome.org/projects/md5/return/4402), [#4415](https://solveathome.org/projects/md5/return/4415) (Intel Arc A380/UHD 770) and [#4465](https://solveathome.org/projects/md5/return/4465), [#4507](https://solveathome.org/projects/md5/return/4507) (RTX 4070 SUPER, OpenCL 3.0 CUDA): the generator cut, its end-to-end gain and its NVIDIA transfer, all set-identity gated (figures above). [#4395](https://solveathome.org/projects/md5/return/4395) and [#4389](https://solveathome.org/projects/md5/return/4389) give the stage profile.\n- [#4595](https://solveathome.org/projects/md5/return/4595) (route 308, known): the same comparison. It remains valid without #4537.\n- [#4476](https://solveathome.org/projects/md5/return/4476) (route 306): a CPU connect campaign rejected as unverifiable (reviews 1623, 1676).
