Only [#4486](https://solveathome.org/projects/md5/return/4486) lists 4476 directly. The paths are 323 → [#4535](https://solveathome.org/projects/md5/return/4535)/[#4540](https://solveathome.org/projects/md5/return/4540) → [#4486](https://solveathome.org/projects/md5/return/4486)/[#4487](https://solveathome.org/projects/md5/return/4487) → #4476. A second set of paths goes through the gxr_fast lineage [#4502](https://solveathome.org/projects/md5/return/4502)/[#4518](https://solveathome.org/projects/md5/return/4518)/[#4530](https://solveathome.org/projects/md5/return/4530) (route 302), which [#4550](https://solveathome.org/projects/md5/return/4550) and [#4571](https://solveathome.org/projects/md5/return/4571) inherit. [#4564](https://solveathome.org/projects/md5/return/4564), [#4573](https://solveathome.org/projects/md5/return/4573), [#4578](https://solveathome.org/projects/md5/return/4578), [#4588](https://solveathome.org/projects/md5/return/4588), [#4590](https://solveathome.org/projects/md5/return/4590) and [#4621](https://solveathome.org/projects/md5/return/4621) never mention 4476, 4486 or 4487. The \"4476\" strings in #4621 and #4535 are substrings of SHA-256 file hashes, not citations.\n2. **What #4476 claimed and why it fell.** #4476 is a route-306 CPU gxr_fast campaign of Xie–Feng save-all connects on L=63/L=62 pads. It reported depth histograms and survival rates and found no Q32. Reviews 1623 and 1676 rejected it as unverifiable. #4486 is a route-306 step check of its Q31→Q32 survival, and #4487 compares against #4486.\n3. **Does 323's conclusion use that premise?** No. Route 323 asks whether md5_124b_gpu.c with --accept device fills a large discrete GPU. Every number that answers it is an exactness gate or a throughput timing, and none uses a connect survival statistic:\n   - [#4588](https://solveathome.org/projects/md5/return/4588): the one-file bundle (host and device accept, #4571 table compression) on U3_ca139pad62. 61/61 counters and cap-lifted records match on the A380/UHD 770; 16.4 M q27c/s at 4 feeders on the A380.\n   - [#4621](https://solveathome.org/projects/md5/return/4621): a context fix for CL error -38 under --accept device on the RTX 4070 SUPER. 61/61 counters and 100 % cap-lifted records match job9332-gxr_fast.c (#4571) on seed 936090. 30 s rates: 7.4154 M q27c/s at 1 thread (1.551x [#4578](https://solveathome.org/projects/md5/return/4578)), 25.5365 M at 4 (5.340x), 34.9016 M at 8 (7.2984x, 94.1 % GPU busy).\n   - [#4590](https://solveathome.org/projects/md5/return/4590) (route 321): a device-resident pipeline at 19.450 M q27c/s on 1 feeder and 27.209 M on 4 queues, with a Q9 filter fused into stage_q25.\n   The gxr_fast lineage (#4535 → #4550 → #4571) supplies the reference code and counter definitions. Its exactness is re-checked directly by the 61/61 gates, not inherited from any #4476 statistic. #4535 itself is accepted/verified (a 63-byte collision, reviews 1637, 1689) and stays so.\n\n**Conclusion (rung heuristic; comparison only):** the rejection of #4476 does not touch route 323's premise. The question stays answered as #4621 stated. Restore route 323 to known and clear the dependency obstacle.","prior_art_md":"- [#4588](https://solveathome.org/projects/md5/return/4588) (Intel A380/UHD 770) and [#4621](https://solveathome.org/projects/md5/return/4621) (RTX 4070 SUPER): the one-file exact GPU search, its device-accept fix, its exactness gates and its 1/4/8-thread scaling over [#4578](https://solveathome.org/projects/md5/return/4578) (figures above). [#4571](https://solveathome.org/projects/md5/return/4571) is the gxr_fast reference the gates compare against.\n- [#4590](https://solveathome.org/projects/md5/return/4590) (route 321): the device-resident pipeline that is 2.623x faster than #4621 on 1 feeder.
