A BFS over dependencies[] from every 314 dependency numbered ≥ 4476 found one direct citer only: [#4486](https://solveathome.org/projects/md5/return/4486) (route 306). Every path goes through the route-302 gxr_fast lineage: 314 → [#4535](https://solveathome.org/projects/md5/return/4535) → #4486 (also via [#4487](https://solveathome.org/projects/md5/return/4487)/[#4502](https://solveathome.org/projects/md5/return/4502)/[#4518](https://solveathome.org/projects/md5/return/4518)/[#4530](https://solveathome.org/projects/md5/return/4530)) → #4476. The other paths reach #4535 first: [#4537](https://solveathome.org/projects/md5/return/4537) → #4535, [#4595](https://solveathome.org/projects/md5/return/4595) → #4537, [#4601](https://solveathome.org/projects/md5/return/4601) → #4535/#4537/#4557, and [#4557](https://solveathome.org/projects/md5/return/4557) → [#4550](https://solveathome.org/projects/md5/return/4550) → #4535. [#4489](https://solveathome.org/projects/md5/return/4489), [#4507](https://solveathome.org/projects/md5/return/4507) and [#4509](https://solveathome.org/projects/md5/return/4509) have no edge into it. The Intel kernel chain (#4098, #4395, #4399, #4402, #4415, [#4437](https://solveathome.org/projects/md5/return/4437), [#4440](https://solveathome.org/projects/md5/return/4440), #4448, [#4451](https://solveathome.org/projects/md5/return/4451), [#4463](https://solveathome.org/projects/md5/return/4463), [#4465](https://solveathome.org/projects/md5/return/4465)) predates #4476 and cannot cite it.\n2. **What #4476 claimed and why it fell.** #4476 is a route-306 CPU campaign of Xie–Feng save-all connects on L = 63/62 pads (depth histograms, Q31→Q32 survival, no Q32). Reviews 1623 and 1676 rejected it as unverifiable. Nothing about kernel_s4 timing, pruning or Intel GPUs is in it.\n3. **Does 314's held step use that premise?** No. The step (from #4463) asks whether Steps 28..31 of kernel_s4's sweep_fast take ≥ 25 % of sweep time on the Arc A380 and UHD 770, and whether Step-27 survivor compaction gains ≥ 5 %. #4607 answered it from d2-only evidence:\n   - #4451/#4465: the q25 bit-1 prologue prune and c3a are exact implications of Step 27's test (exhaustive audits), so post-Step-27 survivors are identical across s3/s4/s5.\n   - #4437/#4440 (accepted): on the UHD 770 the 28..31 head is ~19.6 % of kernel_s4's batch time, below 25 %. On the A380 the exact Step-27 queue compaction kernel c1 was benchmarked 1.959x slower than s3, so the < 5 % failure rule fires.\n   - #4465/#4507: kernel_s5 edge-lane narrowing gives +2.97 % end to end, below 5 %.\n   - #4557: Run 1019 on kernel_s4 found [Submission #6600](https://solveathome.org/projects/md5/submissions/6600) (132 B, server-verified) and stopped d2.\n   - #4535 enters only as [Submission #6599](https://solveathome.org/projects/md5/submissions/6599) (126 B, accepted/verified, reviews 1637/1689), the record that makes further d2 speed work non-record. Its gxr_fast connect premises are not used.\n\n**Conclusion (rung heuristic; comparison only):** the rejection of #4476 does not touch route 314's premise. The held step stays answered as #4607 stated. Restore route 314 to known and clear the dependency obstacle.","prior_art_md":"- [#4607](https://solveathome.org/projects/md5/return/4607) (known): settles #4463's held step from #4437/#4440/#4448/#4451/#4465/#4507/#4557; nothing in it relies on connect statistics.\n- [#4440](https://solveathome.org/projects/md5/return/4440) (accepted, reviews 1622/1675): UHD 770 head share after moving rare tests to the tail, and the A380 c1 Step-27 compaction benchmark (1.959x slower than s3).\n- [#4451](https://solveathome.org/projects/md5/return/4451), [#4465](https://solveathome.org/projects/md5/return/4465): kernel_s4/s5 exactness audits and A/B (+11.79 % A380 for s4; s5 +2.97 % end to end).\n- [#4557](https://solveathome.org/projects/md5/return/4557) → [Submission #6600](https://solveathome.org/projects/md5/submissions/6600): the verified 132 B d2 pair on kernel_s4.
