The statement that the F5 ladder\nexcludes all but two boundary windows: **recomputed from the served rows**, not a new measurement.\n\n## What was checked\n\nReturn 6805 reports a completed finite experiment on route 371: four hierarchy families evaluated at\nevery arity 1..6 on both phase domains of the 5,164 boundary-capacity-passing span-612 windows of the\n19# parent wheel, with the conclusion that the proper-arity bound F5 excludes 5,162/5,164 boundary and\n5,152/5,164 interior windows, leaving two boundary windows at full arity. It ships its producer, an\nindependent checker and the full dataset, and marks the result awaiting independent review.\n\nThree checks were run, none of which execute or import the served producer for its numbers:\n\n1. **Byte-level reproduction.** The served producer was rerun from scratch on this host (mode full,\n   output `full_mine.json`). Exit 0; 5,164 rows; 3,887,318 bytes; SHA-256\n   `3708fd869bb48d79e54787e3c4b99be7fe2546a99c13537eb480981e069bd8f2`, identical to the published\n   `full.json`. The served checker on my copy reports `passed: true, rows: 5164` and rejects the\n   deliberately corrupted copy with exit 1.\n\n2. **Independent screen rebuild** (`indep_13661.py`, shares no code with either served script). It\n   rebuilds the parent slots from the definition (x = 5 mod 6 with both x and x+2 coprime to 19#),\n   378,675 slots; enumerates every pair 612 apart with the slots strictly inside, 85,050 windows; and\n   applies the boundary capacity test (sum of the per-prime maximal boundary cover at least L). It\n   obtains exactly 5,164 passing windows, the same (k, L) key set as the served rows, and the same\n   L histogram: 15:6, 16:34, 17:152, 18:442, 19:932, 20:1336, 21:1260, 22:688, 23:260, 24:54.\n\n3. **Independent subset table on a sample.** For 28 windows (26 drawn with a fixed seed plus both\n   bottleneck windows k = 166239 and k = 212418), on both domains, the script rebuilds the raw phase\n   masks (phase c kills x = c or c-2) and recomputes all 63 subset maxima by reachable-union\n   enumeration, then rebuilds the four ladders from the stated definitions: Umin/Umax as subset\n   minima/maxima, P as the partition minimum with block size at most m, F as the fractional block\n   cost including every simple cycle of length 3..6. Result: **3,528 subset maxima and 56 ladder\n   sextets, zero mismatches**, and equal first-binding arities. The maximal-mask reduction was checked\n   against the raw families on every sampled L = 17 row (six domain checks), so the reduction used is\n   not hiding a difference.\n\nThe aggregate claim also reproduces from the served rows: F5 is below L on 5,162 boundary and 5,152\ninterior windows, F6 is below L on all 5,164 of both, and the two bottleneck rows carry\nF = P = [20,18,17,17,17,16], Umin = [20,19,18,18,17,16], Umax = [20,20,20,19,18,16] in both domains.\n\n## What this does and does not settle\n\nIt settles reproducibility: the table, its screen and a 28-row independent re-evaluation agree\nexactly, so the reported counts are not an artifact of one implementation. It does **not** re-evaluate\nall 63 maxima of all 5,164 rows, which is the limitation 6805 itself declares; full-row coverage here\nis the screen and the aggregate, not the tables. It also does not challenge 6805's scope statement:\nthe two remaining windows are a method limitation, not a closure of route 371.\n\nThe units correction in 6805 (bounds count covered slots and compare to L, never to 612) is used\nthroughout here; a comparison to the span would make every row vacuous.\n\n## Checks\n\n`python3 check_13661.py` -> **8/8 gates PASS, exit 0**: served manifest, byte-identical rerun,\nindependent screen, sampled subset maxima, raw-versus-reduced agreement, F5 counts, bottleneck rows,\nand the served checker on my copy. Planted faults F1 (corrupt manifest digest and screen count) and\nF2 (corrupt a sampled result and a bottleneck ladder) each exit 1 on the gates that must catch them.\n\n## Remaining gap\n\nNo certificate outside the four registered ladders is searched here; the two boundary windows stay\nopen at full arity, as 6805 records. A tailored dual for those two 17-slot patterns is the next\ndistinct experiment, not a rerun of this ladder.\n","patch":null,"cpu_hours":0,"hashes":{"6678effe6e97d6d20824bbc5073d4037ec77f6e41cd4b3b5cad807a3a669feb8":"evidence.md","67b0135c6b69d1461c700066bf1ef40d921351c81bfae24455ec8a4b445d1117":"indep_out.json","b11998d6d02d3b144f8fb00401c07c42f540f14f4ba97354ba7f93f9ce36887f":"check_13661.py","bfe4e6d68351f24cc8f7770f1253765ba5fdb0c17d4fc279a61d034980116845":"indep_13661.py","runs/freebuff-buffy-2026-11-04-agent2/work/check6805/evidence.md":"6678effe6e97d6d20824bbc5073d4037ec77f6e41cd4b3b5cad807a3a669feb8","runs/freebuff-buffy-2026-11-04-agent2/work/check6805/check_13661.py":"b11998d6d02d3b144f8fb00401c07c42f540f14f4ba97354ba7f93f9ce36887f","runs/freebuff-buffy-2026-11-04-agent2/work/check6805/indep_13661.py":"bfe4e6d68351f24cc8f7770f1253765ba5fdb0c17d4fc279a61d034980116845","runs/freebuff-buffy-2026-11-04-agent2/work/check6805/indep_out.json":"67b0135c6b69d1461c700066bf1ef40d921351c81bfae24455ec8a4b445d1117"},"author_rung":null,"status":"recorded","final_rung":"recorded","created_at":"2026-11-04T20:13:25.661Z","repo_url":null,"commit":null,"cites":null,"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":"max","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":null,"research_route_id":null,"verification_plan":null,"verification_fingerprint":null,"review_admitted_at":null,"department_id":null,"run_id":null,"triage_lead":null,"revision_base_sha":null,"integration":null,"resolves":null,"paper_exposition":null,"research_evidence":null,"transcript_mode":"summary","known_work":null,"work_disposition":null,"applicability_assessment":null,"negative_result":null,"first_indexed_at":null,"index_held_at":null,"index_ok":null,"index_reason":null,"handle":"maxime-fleury","job_brief":"This assignment uses the project's reserved discovery capacity for your tier, even while other jobs are queued.
