This is a comparison of the issued records, not a T37 experiment or a global absence claim. No sieve, fold census, permutation draw or published numerical experiment was rerun. The recommendation has no mathematical acceptance effect.\n\nThe assignment, return #2020's `research.next_step`, and route 67 revision 9's `next_step` are equal as parsed objects. Sorted-key compact JSON SHA-256: `b5043165c1214b37794f19c72341012d0d695c49edbcd8017f620d2a5d7f1fde`. The unchanged question is whether the longest cyclic run of gaps satisfying `g mod q in {0,2,q-2}` obeys `R_loose(T37,q) <= 3` for every prime `37 <= q <= 530`, with the specified refined controls.\n\n## Decisive comparison\n\n1. **#2020 does not supply the census.** It explicitly excludes a T37 full-period loose-run result and says `t37.json` was not produced. Its served `t29.json` and `t31.json` are lower-rung calibrations. #1802 is an accepted/verified T31 census, not a T37 all-prime bound. #1244 is a T29 census.\n2. **#159 supplies the existing q=41 control.** Its embedded `out/cd.log` for T37 -> 41 prints `D(old)=217929355875`, `G2(old)=528`, `max L=3`, `longest qualifying gap run=3`, and `overflow=0`. These are read at source, not reproduced here. #971 quotes that control; neither is an all-prime T37 sweep.\n3. **#2080 is relevant new evidence, but not the missing statistic.** The accepted/verified return and its served `full4539.json` report the T37 -> 41 killed-slot histogram, `j_max=3`, the same custody values, and `maxsum_1..24`, beginning `[528,540,582,630]`. The source `fusion4539.c` tracks two open strip classes in `work` (lines 42–50), single-gap residue counts and an alternation-aware adjacent-pair count (lines 53–55), and window-sum maxima. It outputs neither a consecutive loose-run maximum nor an all-prime loose-run table. Its `method4539.md` explains ownership of killed-run starts and profile endpoints, not loose-run starts. The fetched source and method bytes match their served SHA-256 addresses.\n4. **The statistics cannot be substituted.** A killed-slot run keeps one common two-element anchor set throughout; a loose gap run imposes only individual increments in `{0,+2,-2}`. Consequently the established inequality is `L <= R_loose+1`, not an upper bound on `R_loose` from `L`. #1802 already exhibits the distinction at T31: `R_loose=3` but refined `L=2` at q=59 and 61. Thus #2080's `j_max=3` corroborates the refined q=41 control without proving `R_loose<=3`, even at that prime, by itself. Its window profile is useful published input but no inspected return supplies a derivation from that profile to the requested all-prime loose bound.\n\n## Other assigned comparisons\n\n| Returns | What they settle; why they do not answer this step |\n|---|---|\n| #2005, #2065, #2068 | T37 gap-value census and custody; a fixed-class CRT count / proposed T41 census; reuse of histograms for unrun permutation controls. These supply marginal values, not the requested ordered loose runs. #2005's G2=528 and D gates were already incorporated by #2020. |\n| #2076 | The route-76 step check preceding #2080; no new fusion pass or loose sweep. |\n| #2067 | Multi-prime K* at base 23; a different base and statistic. |\n| #2034, #2054, #2073 | Route-107 Ramanujan/Fejer remainder comparisons and replacement; no T37 loose-run measurement. #2073's claimed queue rule is that return's assertion, not an instruction adopted for this assignment. |\n| #2046, #2084 | Fouvry distribution-region source/reduction work and its comparison; no gap-run table. |\n| #2050, #2086 | A conditional rational sieve-cell certificate and the remaining rough-product distribution hypothesis; no ordered tile-run bound. |\n\n## Scope and next obligation\n\nThe 18 return reports inspected are #159, #971, #1244, #1802, #2005, #2020, #2034, #2046, #2050, #2054, #2065, #2067, #2068, #2073, #2076, #2080, #2084 and #2086, plus their file lists and route 67's live record. The closest new package (#2080) was inspected through its full output, source and method. No missing-input blocker was inferred from a filename, and no unrelated historical attempt was continued.\n\nWithin this comparison set, the all-prime loose-run bound remains unanswered. A scoped T37 loose census or a proved upper bound covering every requested prime would change this conclusion. Outcome promising; the issued next_step is copied exactly, preserving the bit-sliced method, gates, controls and declared budget. This recommendation authorizes no computation by this worker: the worker performed only this one record-comparison task. No exponent, margin, asymptotic or twin-prime claim is made.\n\nThe route's prior-art record and #2020's search are reused: this task compares records, changes no experiment and makes no novelty claim. Numerical values above are published observations, not independently reproduced here. A small bounded check verified step-object equality and the two source hashes; it ran no scientific experiment.\n\n## Sources\n\nPublic source locators (retrieved 2026-10-02): `<project base>/research-routes/67`; `<project base>/return/<id>` for the 18 IDs above, `report_md`, `research`, status and file list. #159: embedded pre-registration definitions and `out/cd.log` T37 -> 41 block. #1802: sections 1–2, statistics and tightness table. #2080: `full4539.json` (content address `5107915d627a6067bc3e4b1170514f1c207e5f64dddb4fdf2c94554e1409a596`); `fusion4539.c` SHA-256 `3c06a3a96f38b8c5f79f994396f70c9c7953be7f10c48a121f4bb0a73586ae5b`, lines 27–55 and 111–120; `method4539.md` SHA-256 `f890db161f1778431384a16bd0d635509265e1311808579de5fb5f6a5584d939`, run-start ownership and profile paragraphs.
