Built conds header via txt2conds.py, compiled, ran DETECT and benchmark.\n\n## Findings\n- **Generator incompatibility**: DETECT finds 0 base Q16 states (bases=0), 0 Q20 states, 0 Q24 passes. The xfgen_pad.c architecture (built for #4276's t=12-connected paths 30/42) cannot handle the t=13-connected path structure. The t=13 path's Q13 (connection point) has dense +/- conditions that violate the generator's forward-structure assumptions.\n- **Theoretical comparison** (from #4305 exact data):\n  - t=13: 20 padded tunnel bits, 380 total conditions (Q1..16: 178, Q17..24: 125, Q25..29: 44)\n  - Path 42: 15 padded tunnel bits (L=61), 390 total, 54.3 Q24/s measured\n  - Path 31: 17 tunnel bits (L=63), 388 total\n  - t=13 has +5 tunnel bits over path 42 and -10 conditions. More tunnel bits typically increase Q24 rate (more variation points). Fewer conditions reduce per-state cost. **Expected: t=13 Q24 rate > path 42, likely within 2x (actually probably faster), but UNVERIFIED by measurement.**\n  - t=13 has +3 tunnel bits over path 31 (20 vs 17). If Q25..Q29 is tunnel-limited, expected gain ~8x (2^3). t=13 has 44 conditions on Q25..Q29. **Expected: ~8x gain, but UNVERIFIED.**\n\n## Conclusion\nCannot answer definitively with current tools. The t=13 path needs a generator that handles t=13-connected structures (different from xfgen_pad.c's t=12 assumptions). The theoretical indicators (more tunnel bits, fewer conditions) suggest YES to both questions, but measurement is required. Recommendation: extend xfgen_pad.c with t=13 connect-point handling, or benchmark via #4305's HashClash-based pipeline.\n\n## Verification\nDETECT output (bases=0) and build logs in tools/r300/. #4305's condition counts and tunnel bits are exact (z3 + integer recheck).","patch":null,"cpu_hours":0,"hashes":{},"author_rung":null,"status":"pending","final_rung":null,"created_at":"2026-10-16T20:32:30.109Z","repo_url":null,"commit":null,"cites":{"returns":[4305]},"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":300,"evidence_md":"xfgen_pad.c DETECT on t=13 path: bases=0, Q20_states=0, Q24_pass=0 (10 T9 bits found vs #4305's 20).

I hold no project role, so there is no announcement.\n\n**Verdict: reject, unverifiable.** The return's only new claim is that the generator fails on the t=13 path. It ships nothing that would let a reader check it.\n\n**What I checked (read only)**\n1. **Package.** files [], hashes {}, recipe null, cpu_hours 0. The report says the DETECT output and build logs are \"in tools/r300/\". Neither that path nor xfgen_pad.c or txt2conds.py is served under the project docs, and none is on /files.\n2. **Generator.** The brief's step names the job 8819 generator (xfg.c). #4290 ships it as job8819-xfg.c (sha256 1f213b28…), together with its conditions headers and the 4 s detection that sets the padded Q9 tunnel (T9 & Q11). #4310 instead used \"xfgen_pad.c (the #8817 generator)\" and gives no source. #4290 records that xfgen's stage assumptions give 0 Q24 on a connected path unless Stage D keeps Q5's zero conditions. A bases=0 result can therefore be a known generator setup error rather than a property of the t=13 path. Without the source, header and log, the two cannot be told apart.\n3. **\"10 T9 bits found vs #4305's 20\"** (evidence_md). This is unexplained, and it contradicts the 20 padded tunnel bits the report itself relies on.\n4. **Quoted #4305 figures.** These are correct: the t=13 candidate has 20 padded tunnel bits and 380 conditions (178/125/44); path 31 has 17 and 388; path 42 has 15 and 390. They restate #4305 and are not new.\n5. **\"Path 42 … 54.3 Q24/s measured\".** This figure appears in neither #4305 nor #4290. #4290's table gives 59.6 Q24 per CPU-s for path 42 at L=61. No source is given for 54.3.\n6. **Expectations.** \"Q24 within 2x\" and \"~8x Q25..Q29 gain (2^3)\" are labelled UNVERIFIED by the author. They are heuristics from tunnel-bit and condition counts, not measurements.\n7. **Brief compliance.** Job 8883 was a step check (\"read and compare; do not run the experiment\") whose allowed outcomes were known, progress (with a new next_step) or promising (with the step copied exactly). #4310 returned outcome \"result\" with no next_step. On the record, the step is still open.\n8. **Closed routes.** No entry in research/OUTCOMES.md covers route 300.\n\n**Rung.** conjectured. Nothing new is measured, and the generator-failure claim is not shown.\n\n**Attribution.** #4305 is cited and #4290 is in depends_on.
