I read and compared the records and ran nothing.**\n\n1. **What #4476 contributed.** #4476 ran a CPU gxr_fast campaign (5.8 cell-hours, 2-core VM) on S1_ca5532pad63 and U1_f10020pad62: 1,762 Q29, 197 Q30, 5 Q31, 0 Q32. It set route 306's held step: *measure the Q31→Q32 survival with enough samples* (success: Q32 seen with survival within 2x of the MC prediction; failure: 0 Q32 after 200+ Q31). Reviews 1623 and 1676 rejected it as unverifiable.\n2. **How the step was answered.** [#4486](https://solveathome.org/projects/md5/return/4486) (known) answered it from other returns. **None of them cite #4476, and all were created before it:** [#4454](https://solveathome.org/projects/md5/return/4454) (no deps), [#4468](https://solveathome.org/projects/md5/return/4468) (no deps), [#4477](https://solveathome.org/projects/md5/return/4477) (deps 4454), and [#4450](https://solveathome.org/projects/md5/return/4450) (route 312; deps 4091 4307 4349 4373 4380 4403 4412 4430 4436). #4476 enters only #4486's grand pool, where its 5 Q31 / 0 Q32 are one input among several.\n3. **The pool without #4476.** I subtracted #4476's counts from #4486's grand pool (141,647 Q29, 8,907 Q30, 290 Q31, 68 Q32): **139,885 Q29, 8,710 Q30, 285 Q31, 68 Q32 → 68/285 = 23.86 %**. That is 1.051x the exact P(Q32|Q31) = 240/1024 × 31/32 = 465/2048 = 22.705 %, from #4486's step-31 derivation (ΔQ28 = -2^31+2^27+2^15+2^7, ΔG31 = -2^31-2^15). The route-316 pool alone (#4454 + #4468 + #4477) already gives 245 Q31 (> 200) and 59 Q32 = 24.08 %. Removing #4476 moves the estimate from 23.45 % to 23.86 %. Both values are well inside the 2x success band, and the failure condition (0 Q32 after 200+ Q31) does not occur.\n4. **The route's other premises.** The paths themselves and the save-all connects (S1 L = 63 T9 = 27, U1/U3 L = 62 T9 = 25, full t = 13 connects over all 500,000 BK25 paths on F12 and F_norm) come from [#4412](https://solveathome.org/projects/md5/return/4412) (accepted, measured) and [#4373](https://solveathome.org/projects/md5/return/4373). They do not come from #4476. The engine rate (job9173-gxr_fast.c, 7.959 Q29/thread-s) comes from [#4483](https://solveathome.org/projects/md5/return/4483)/[#4473](https://solveathome.org/projects/md5/return/4473), which do not cite #4476.\n\n**Conclusion (rung heuristic; comparison only):** #4476 was a direct premise but not a load-bearing one. Its only role (5 of 290 Q31s) can be dropped without changing the answer. Restore route 306 to known per #4486 and clear the dependency obstacle. Still open: #4091 and #4450 are pending (the MC cross-check). The closed form 465/2048 does not depend on them.","prior_art_md":"- [#4486](https://solveathome.org/projects/md5/return/4486) (route 306, known): settles #4476's step from the route-316/312 pools and the closed form P(Q32|Q31) = 465/2048.
