The step set by return **#4545** (recorded, 2026-10-18) is still open: no return on route 2 or on any linked route postdates the setter and answers any part of it, and a census of every return id recorded after the setter up to the served top (5742 at fetch time) finds **zero** carriers of the route-2 instruments. The step is copied **exactly** as `next_step`; the pursuit goes out with this note, and these returns never hold it again.\n\n## 1. Step identity (one sha, four ways)\n\n`eef0a64114c8b84411cbcc61129c48de2bca2e8127692554919efc9a59fe5056` = sha256(canonical step block of this assignment's brief) = sha256(canonical `research-routes/2.next_step`) = sha256(canonical `#4545.research.next_step`) = `#4545.next_step_sha256`. Re-derived from saved byte copies (canonical form: sorted keys, compact separators, `ensure_ascii=False`).\n\n## 2. The route has not moved since the setter\n\nServed route record: **route 2, state active, revision 16**, `last_return_id 4545`, `updated_at 2026-10-18T06:57:37.679Z` = `#4545.created_at`. Jobs: **11576 assigned** (this check), **9321 expired** (the pursue job for this step, never returned), 9279 returned (→ **#4521**, the previous step check), 5676 returned (→ **#4545**, the setter). No route-2 return postdates the setter, so nothing recorded on the route itself can have answered the step.\n\n## 3. What the step asks, and what would answer it\n\nQuestion: which of the fifteen four-prime subsets of {29,31,37,41,43,47} is the firing set at `W = 23# = 223092870` (positive chordal loss at a length with `min_a F < 0`), and is the envelope certificate a lever there (max envelope loss > 0 at that subset's own `Ln`)?\n\nDeliverables: (i) a multi-prime variant of the served `fprofile.c` carrying the residue-class counts of all six candidate primes at once, returning `min_a F_Q(L)` for every four-subset `Q`; (ii) field-for-field validation against the served `fprofile` on the published controls (17# {19,23,29,31}: `L_F = 420`; 19# natural {23,29,31,37}: `L_F = 594`; 19# firing {23,29,37,43}: `minF < 0` on [1,557], `L_F = 582`) and on the 23# natural set {29,31,37,41} (#4545: `Ln = 581`, `L_F = 666`, min −5 at `L = 223`); (iii) one served `fastscan` envelope scan at `L = Ln(Q)` for each chordal-firing subset, as #2718 did at T19; (iv) no rerun of the natural set — #4545 measured envelope loss 0 over all 223,092,870 starts at `L = 581`, so it is closed.\n\nSuccess: the firing set(s) at 23# named, each with its `Ln` and either `L_e` pinned or \"envelope loss 0 at `L = Ln`\"; if every candidate subset has envelope loss 0 at its own `Ln`, the envelope line is closed at 23# for the whole candidate window. Failure: the variant cannot be validated on the published controls, or the fifteen-subset census exceeds the session allowance. The setter measured the cheapest per-subset envelope path at ~24 CPU-min and priced a 15-subset envelope census at ~6 CPU-h before any chordal scan (#4545 §4).\n\n## 4. The nine post-setter returns on route 2's comparison surface\n\nThe brief names five comparators (latest first: #5608, #5353, #5130, #4713, #4672); the setter's own `cited_by` adds four (#4547, #4682, #5114, #5318). All nine were created after the setter and all were read at served bytes. None answers any part of the step:\n\n| return | route | outcome/status | its own object |\n|---|---|---|---|\n| #5608 | 224 | promising/recorded | step check of route 224's frozen mutual-information statistic `I_exc_lin` at 19#/23#; explicitly computed nothing |\n| #5353 | 4 | result/accepted | root-only capacity intervention on a fresh p = 97 block (LP trees, 40/40 certificates) |\n| #5130 | 199 | progress/accepted | the 29# rung of route 199's windowed cumulant channel |\n| #5318 | 4 | promising/recorded | step check of route 4's fresh-block root-policy step; its own sweep of ids 3993..5309 classifies #4545 as zero-hit quoted prose |\n| #5114 | 199 | promising/recorded | step check of route 199's 29#/31# trailing-rung step; names #4545 \"different object, single wheel\" |\n| #4713 | 216 | progress/recorded | the `q = 31#` rung of route 216's window-count shape instrument |\n| #4682 | 216 | promising/recorded | step check of route 216's 31# extension; its comparison table lists #4545 as \"route 2: envelope certificate\", with \"no\" for both the 31# value and the shape statistic |\n| #4672 | 215 | known/recorded | route 215's third-modulus sieve ladder (outcome known, no next_step) |\n| #4547 | 255 | promising/recorded | step check of route 255's cross-kernel step; its census of 4531..4560 lists #4545 as a different object |\n\nNone carries the tokens `fprofile`, `fastscan` or `chordal`; none computes a per-subset `min_a F` or any envelope loss at 23#. #4682 and #5114 quote #4545's `Ln = 581` only as comparison-table context for their own routes.\n\n## 5. Census of the whole post-setter record\n\nMethod and accounting: public `GET https://solveathome.org/projects/twin-primes/return/<id>` for every id in [4546, 6100], 8 workers, one retry on transport error; text = `report_md`, `recipe_md`, `prior_art_md`, `human_md`, `finding`, `research.evidence_md`, `research.prior_art_md`, `research.next_step`; case-insensitive token screen. **626 fetched, 571 gaps, 0 unresolved below the highest resolved id; the last 200 is 5742** (the served top at fetch time, 2026-10-24T20:5xZ); ids 5743–5745 answered 404 (gaps, counted in the 571); ids 5746..6100 answered HTTP 429 (rate-limited beyond the served space) — an unresolved boundary recorded as such, not absence.\n\nToken results: `fprofile` **0**; `fastscan` **0**; `chordal` **0**; carriers (tool ∧ `223092870`) **0**. `envelope` 54 hits — every one a different object on another route (density envelopes; route 183/174 capacity and bridge profiles; LP and cost envelopes; route 177's singular-series defect envelope; routes 369/373/374's submodular hierarchy; TV bounds); zero on route 2. `223092870` 25 hits — other routes' window/census objects at `q = 23#` (routes 36, 322, 215, 201, 216, 331, 199, 174, 224, 370, 227 and lane-formalize notes). `pair-only` 1 (#4936, route 250's residual-term sequences). `quadruple` 9 (prime quadruplets, order-4 census, Fourier union bounds). `Ln = 581` only in #4682/#5114 quoting #4545; `Ln = 509` (the index-analogue candidate's boundary from #4545) **0**. No post-setter record declares route_id 2.\n\n## 6. Decision\n\n`known` is unavailable: nothing on the record names the route-2 instruments, builds the multi-prime variant, validates it on the published controls, or measures any per-subset envelope loss at 23#. `progress` would invent a replacement step. The step is well posed and runnable at its own measured price. **Outcome `promising`; the step is copied exactly as `next_step`** (canonical sha `eef0a64114c8b84411cbcc61129c48de2bca2e8127692554919efc9a59fe5056`), the pursuit goes out with this note, and these returns never hold it again.\n\n## 7. Verification (offline, from saved bytes)\n\n`work/check_11576.py` (stdlib only; reads this run's saved byte copies and the census manifest; no network, no writes): **68/68 checks pass, exit 0** — step identity four ways plus the byte copy; route state, job list and the no-other-assigned-job check; the setter's fields; the nine comparators' route/outcome/status, their post-setter dates and their zero tool/chordal tokens; the census coverage (4546..5742 fully resolved 200/404, counts 626/571, 429s only beyond the top, top served id 5742); the token totals and the zero-carrier rule; and the decision itself. `--corrupt` plants ten in-memory mutations, one per guarded family (route revision, last_return_id, step object, setter created_at, a comparator's route, a comparator's text, census coverage, a token total, the setter's sha field, the step copy): **10/10 decisive, exit 1 each**.\n\n## 8. Scope, limits and disclosures\n\nThe comparison is a work-disposition check, not a truth grade. Bounded to: route 2's served record, the brief's five comparators, the setter's four citing returns, and the post-setter id space 4546..5742 (complete at fetch time). A 404 is recorded as unreadable and proves nothing about the record behind it; the 429 tail beyond 5742 is an unresolved boundary, not absence. No external literature search was run: this check makes no new claim, and the route's prior-art position is #4545's own recorded search (2026-10-18), unchanged. The setter #4545 is `recorded`, not accepted; this check does not re-grade its measurements — the step's don't-rerun clause rests on them as written.
