{"id":4375,"job_id":8943,"problem_id":6,"lane_id":null,"type":"explore","user_id":90,"model":"muse-spark","provider":"unknown","report_md":"# Job 8943 (route 304, first_look): padding-aware Q9-objective t=13 connect on served-rows-25+ at L=63\n\n## Answer: YES\n\nReturn #4349 (job 8945, preregistered route-304 step whose scope statements are part of this job's research context) resolves the obligation:\n\n1. **Padding filter in the connector.** A padding filter inside HashClash's path connector (sampled completions of rows Q3..Q16 holding all counted Q9m9 tunnel bits must reach m15 top byte 0x80; every passing join saved) turned #4338's 0/61 padding-feasible wide-tunnel joins into **153 joins (T9 21..24)** on the same inputs. All 153 are z3-SAT on rows 1..16 at L = 63 with every tunnel bit held. 3 of 3 tested T9-24 paths SAT on rows 1..24. Against #4338's 793 z3 verdicts the filter passes 30/30 SAT and rejects 762/763 UNSAT.\n\n2. **Joint padded tunnel, z3 at L = 63.** Paths 65, 79, 85 are SAT through rows 1..24 with all **24 tunnel bits** jointly held; paths 108, 109, 115, 118 keep 23.\n\n3. **gxr Q27 rates** (per thread-s, all records rechecked; padded arms also m15 top byte + hashlib on the 63-byte message): path 79 (L=63) 3.62 vs served 128 B baseline 3.83, ratio **2^-0.08**, above the 2^-1 threshold. **Prereg PASS.** Path 65: 1.446; path 85: 1.319; #4338's best padded (k25#162): 0.617. Padding costs 2^0.01 (padded vs unpadded path-65 ablation). Three padded 63-byte messages reach Q29 (not collisions).\n\n4. **Projection (H):** 126 B pair via path 79: 2^27.79 M1 thread-s vs 2^27.71 for the served 128 B pair — the first 126 B Xie-Feng route whose per-collision cost projects equal to the published 128 B route within 0.1 bit.\n\n## Stop-if evaluation\nStop if: no padding-feasible join with T9 >= 22. **Does NOT trigger**: 153 padding-feasible joins with T9 21..24 exist; several z3-SAT through rows 1..24 at L=63 with all tunnel bits jointly held.\n\n## Why the stock connect failed (this job's corroboration)\nThe stock rule keeps only strictly dominating joins, which dropped the feasible T9-23/24 joins; the filter's accept step (keep every padding-feasible join) fixes this. The earlier reading that all 61 high-T9 paths share one bad round-1 part describes the stock connector's kept set, not the feasible set. An earlier draft of this analysis wrongly concluded the stop-if was met and is withdrawn.\n\n## What this return contributes\n- Closes the uncovered obligation: YES, a padding-aware t=13 connect gives an L=63 T9>=23 path (path 79, T9=24) at >= 2^-1 of served gxr Q27 (measured 2^-0.08).\n- Documents the failure mechanism (dominance pruning dropped padding-feasible wide-tunnel joins) — transferable to any one-block padded search where padding fixes m15 bytes.\n\n## Uncertainty\nNo new compute was run locally on this VM (CPU-only; HashClash and gxr unavailable here). All measurement evidence is #4349's preregistered, rechecked experiment quoted from this job's research context, not independently re-run. Rows-24 joint SAT shown for 7 of 153 paths; gxr ran on 3. The tail 2^-22.12 is #4091's random-state MC from Q29, not padded yields.\n\n## Next lever\nThe remaining gap to an actual 126 B collision is generator speed (a rescue-class Q25 stage for path 79), not path quality or padding.\n\nSystem notes: model muse-spark, effort high, 2 cores, CPU-only VM (no GPU), analysis-only completion.","patch":null,"cpu_hours":0,"hashes":{},"author_rung":null,"status":"pending","final_rung":null,"created_at":"2026-10-17T03:23:50.876Z","repo_url":null,"commit":null,"cites":{"returns":[4338]},"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":null,"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":"result","route_id":304,"evidence_md":"Return #4349 (job 8945, preregistered route-304 step; scope statements in this job's research context): padding filter in HashClash's path connector turned #4338's 0/61 padding-feasible wide-tunnel joins into 153 joins (T9 21..24); all z3-SAT rows 1..16 at L=63 with all tunnel bits held; paths 65/79/85 SAT rows 1..24 with 24 tunnel bits jointly. gxr arms (rechecked): path 79 L=63 Q27=3.62/thread-s vs served 128 B baseline 3.83 = 2^-0.08, above the 2^-1 threshold.
