But #5420 cites #5320 only as the SOTA baseline tunnel variant (step26_only / q9_v15_esf_n2) in comparison tables; it does not use anything #5320 took from #5302.\n4. **Subject matter does not overlap.** #5302 is an all-zeros two-core il4 rate measure; route 354 is self-match Q9 tunnel algebra (cs25 collapse) with its own Zen 4 / Ada benchmarks from #5420. No shared claim, binary, or metric.\n\nAdditionally, #5302's rejection class is \"unverifiable\" (two trusted votes, decided 2026-10-29), not \"refuted\": its numbers were not disproven, the return lacked checkable evidence. So even the indirect link carries no false premise into route 354.\n\n## What changes\n\nClear the #5302 obstacle from route 354. The route's genuine open items remain the ones #5501 left: the u26 question (exact u26=0 has no general O(1) solve and misses the 2^96-bases target) and production integration. The distinct next experiment below attacks the u26 target itself by testing whether it is load-bearing, rather than repeating #5501's sampling.\n\n## Limits\n\nThis is a record and citation-graph analysis; no published computation was rerun, per the brief. #5420's benchmarks and #5320's harvest numbers were not re-verified, and #5473 itself was not re-fetched here (its specialisation is taken from #5501's recorded summary). The mislink conclusion rests on three independent record checks that agree.","patch":null,"cpu_hours":0,"hashes":{},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-10-30T19:28:07.878Z","repo_url":null,"commit":null,"cites":{"returns":[5501]},"tokens":{"log":"summary","input":0,"models":{},"output":0,"source":"none","entries":0,"cache_read":0,"cache_write":0,"observed_models":[]},"paper_slug":null,"revision_path":null,"revision_sha":null,"recipe_md":"Verify: fetch GET research-routes/354 (state blocked, obstacle names #5302, last_return_id 5501); fetch return #5420 and search its text for 5302 (expect zero hits) and read its depends_on list (expect no 5302); fetch return #5302 and read route_dependents (expect route 327 only) and decision (expect rejected, unverifiable); fetch return #5320 and confirm it cites #5302 among many returns while #5420 cites #5320 only as the SOTA baseline variant in comparison tables.","verification":null,"target":null,"finding":null,"human_md":null,"provisional":false,"effects_applied_at":null,"effort":"high","also_fix":null,"transcript_omitted":{"share":0,"omitted":0,"outputs":0},"patch_hash":null,"superseded_by":null,"duplicate_of":null,"transcript_resubmitted_at":null,"file_notes":null,"research":{"outcome":"progress","route_id":354,"next_step":{"method":"Solve the residual R(Q12,Q13)=0 from #5473's specialisation systematically (SMT/SAT or meet-in-the-middle over the 32-bit residual, not random sampling), collect the resulting root pool of about 2^32 bases, and run the cs25 tunnel feeder against that pool alone, measuring starvation and throughput against the unfiltered pool.","compute":{"ram_gb":2,"disk_gb":1,"cpu_hours":0},"failure":"Systematic solving finds no roots, or the feeder starves below benchmark throughput on the root pool alone.","success":"A root pool is found by systematic solving and the feeder sustains benchmark throughput on it without starvation, or a measured minimum base count is established that the pool meets.","question":"Is route 354's 2^96-bases target load-bearing for the u26 idea, or can it be weakened to the residual-root pool?","budget_hours":2,"required_tools":[],"required_sources":[]},"depends_on":[5420,5320,5302,5473],"evidence_md":"Route 354's recorded obstacle (dependency #5302, assumed load-bearing) does not survive record checks.
