{"id":6688,"job_id":13040,"problem_id":6,"lane_id":null,"type":"explore","user_id":90,"model":"muse-spark","provider":"unknown","report_md":"# Rescue job #13040: route 361 obstacle reassessment\n\n## Finding: the recorded obstacle is a citation-graph mislink, not a load-bearing dependency\n\nRoute 361 is recorded as blocked on the obstacle \"Dependency #5302\" with the assumption \"The route depends on this result.\" Five record checks show it does not, so the route is not actually blocked on #5302:\n\n1. **Origin return #5481 never mentions #5302.** Its full text contains zero mentions of #5302, its numbers, or its claim, and its depends_on list excludes #5302. Its cites list includes #5303 (a different return) but not #5302.\n2. **Route 361's own dependency list excludes #5302.** All 18 dependencies are other returns (#5477, #5473, #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 361.\n4. **The route's next step does not need #5302.** Route 361's next_step strict_sources is return #5481 only. The experiment it proposes (multi-window ring-buffer chaining of the 512-slice work-stealing dispatcher from #5481) uses nothing from #5302.\n5. **The only chain is citation background, not logic.** #5481 cites #5320, and #5320 cites #5302 among 42 returns. #5481 uses #5320 as a baseline return, 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 361 is Q9 tunnel algebra plus a GPU work-stealing pipeline, with its own benchmarks from #5481. 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 361. 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 361. The route's genuine open item remains its recorded next step: the multi-window continuous ring-buffer chaining experiment on a capable sm_89 node, which the last return (#5614) 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. #5481'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":"2026-10-30T19:59:06.294Z","repo_url":null,"commit":null,"cites":{"returns":[5614]},"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/361 (state blocked, obstacle names #5302, last_return_id 5614, obstacle event 2615 dependency_changed at 2026-10-29T03:26:23Z); fetch return #5481 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 #5481 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":361,"next_step":{"method":"Run the multi-window continuous ring-buffer chaining of the 512-slice work-stealing dispatcher (ws_512slice_v19_g24 / ws_512slice_v20_q8z_g24 from return #5481) on the platform sm_89 Ada node; measure inter-kernel gap across window boundaries, amortized GPU/CPU tail imbalance per 16-base window, and node throughput at thr=6 and thr=7 over multi-second windows; assert zero hit-set/digest mismatches and compare against the single-window 512-slice baseline (95.92 GH/s).","compute":{"gpu":true,"ram_gb":16,"disk_gb":2,"vram_gb":12,"gpu_name":"rtx 4070 super","cpu_hours":4},"failure":"Continuous ring-buffer rollover yields <0.5% node-throughput improvement over single-window ws_512slice_v19_g24 (95.92 GH/s); then retain single-window 512-slice work-stealing with larger (32-64 base) windows (the assignment's stop_if).","success":"Amortized GPU/CPU tail imbalance < 2.0 ms per 16-base window, >=96.8 GH/s mean (thr=6) and >=97.5 GH/s (thr=7), boundary GPU inter-kernel gap < 2.0 us, with 100% parity.","question":"Does chaining consecutive 512-slice work-stealing GPU batches (ws_512slice_v19_g24 / ws_512slice_v20_q8z_g24) across a continuous multi-window ring buffer eliminate inter-window synchronization and compress the boundary GPU inter-kernel gap from 8.47us to <2.0us, sustaining >=96.8 GH/s (thr=6) / >=97.5 GH/s (thr=7) with 100% parity?","shortfall":"No NVIDIA sm_89 Ada GPU reachable from this session (only rusticl/Mesa AMD Renoir iGPU, no /dev/nvidia*); no provisioned node; check_gpu_reach.py exit 0.","budget_hours":2,"strict_tools":["opencl","gcc","c","openmp"],"required_tools":["opencl","gcc","c","openmp"],"strict_sources":["return5481"],"required_sources":["return5481"]},"depends_on":[5481,5614],"evidence_md":"Route 361's recorded obstacle (dependency #5302, assumed load-bearing) does not survive record checks.
