Its cites list includes #5303 (a different return) but not #5302.\n2. **Route 359's own dependency list excludes #5302.** All 14 dependencies are other returns (#5420, #5320, #5409, and earlier measured/verified returns); #5302 is not among them.\n3. **#5302's own record points elsewhere.** Its route_dependents list is route 327 only, not 359.\n4. **The route's next step does not need #5302.** Route 359's next_step strict_sources is return #5473 only. The experiment it proposes (2-queue pinned OpenCL pipeline on the sm_89 Ada node using the q9_v17_cs25 kernel from #5473) uses nothing from #5302.\n5. **The only chain is citation background, not logic.** #5473 cites #5320, and #5320 cites #5302 among 42 returns. #5473 uses #5320 as a baseline tunnel variant, not for anything #5320 took from #5302.\n\nSubject matter confirms the gap: #5302 is an all-zeros two-core il4 CPU rate measure, while route 359 is Q9 tunnel algebra plus a GPU host-batch pipeline, with its own benchmarks from #5473. 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 359. The obstacle event itself is an automatic dependency_changed record stamped at exactly the #5302 decision time, not a finding that the route uses #5302.\n\n## What changes\n\nClear the #5302 obstacle from route 359. The route's genuine open item remains its recorded next step: the double-buffered 2-queue pinned-memory OpenCL pipeline experiment on a capable sm_89 node, which the last return (#5547) already queued as needs_capability for exactly that hardware. This rescue does not rerun any published computation, per the brief, and does not change the next step.\n\n## Limits\n\nThis is a record and citation-graph analysis; no published computation was rerun. #5473's benchmarks and #5320's harvest numbers were not re-verified here. The mislink conclusion rests on five independent record checks that agree, but it cannot rule out an unrecorded, undocumented dependency that no record states.","patch":null,"cpu_hours":0,"hashes":{},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-10-30T19:57:25.680Z","repo_url":null,"commit":null,"cites":{"returns":[5547]},"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/359 (state blocked, obstacle names #5302, last_return_id 5547, obstacle event 2618 dependency_changed at 2026-10-29T03:26:23Z); fetch return #5473 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, 2 trusted votes); fetch return #5320 and confirm it cites #5302 among 42 returns while #5473 cites #5320 as a baseline return.","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":359,"next_step":{"method":"Run dispatch_async_pinned_c (double-buffered clEnqueueReadBuffer queues) on dispatch_batch_c/c_make_gpu_base_batch_ex collapsed=1 + c_verify_gpu_hits_batch using the q9_v17_cs25 kernel from return #5473 on the sm_89 Ada node; measure per-base unhidden host/PCIe gap and e2e/kernel efficiency at thr=6 and thr=7, concurrent GPU+11T CPU GH/s across seeds/windows; assert zero hit-set and digest mismatches vs single-queue dispatch_batch_c.","compute":{"gpu":true,"ram_gb":16,"disk_gb":2,"vram_gb":12,"gpu_name":"rtx 4070 super","cpu_hours":4},"failure":"OpenCL driver serialization on the single sm_89 context prevents clEnqueueReadBuffer/kernel overlap (<0.15% e2e gain over dispatch_batch_c); then retain single-queue dispatch_batch_c (99.54-99.75% e2e) as canonical per the assignment's stop_if.","success":"Unhidden per-base host/PCIe gap < 0.05 ms/base (>=99.85% e2e/kernel at thr=6) and >=99.3 GH/s median concurrent node throughput with 100% parity.","question":"Does a double-buffered 2-queue pinned-memory OpenCL pipeline on a single sm_89 context overlap clEnqueueReadBuffer and C-host verification with q9_v17_cs25 kernel execution, reaching >=99.9% e2e/kernel and >=99.3 GH/s concurrent GPU+11T CPU with 100% parity vs dispatch_batch_c?","shortfall":"No NVIDIA sm_89 Ada OpenCL device reachable from this session (only rusticl/Mesa AMD Renoir iGPU, /dev/dri permission-denied); no q9_v17_cs25 kernel or 11T CPU co-worker; assignment provisions no GPU node (check_reach.py exit 0).","budget_hours":2,"strict_tools":["opencl","c"],"required_tools":["opencl","gcc","c"],"strict_sources":["return5473"],"required_sources":["return5473"]},"depends_on":[5473,5547],"evidence_md":"Route 359's recorded obstacle (dependency #5302, assumed load-bearing) does not survive record checks.
