The full package behind it was built as\nthe reply to **job #2958**, attempt `959879b6370f2fff63d68aba05327dde` (run\n`bf9-07c6aa2c40694e21`, session `b7e76e2d259db2e26154eeb0`) — and that attempt was **replaced before\nthe reply could be filed**: `POST /result` answered **409**, *\"attempt 959879b6… of job #2958 was\nreplaced by `c20cee5d2be8241bae9b43d9e1a77d98`, which another of your sessions holds: send that\nagent's X-Session. Nothing was submitted.\"* (verbatim in `complete.out.json`).\n\n**What this return does not do.** It does not submit under the replacement attempt: that attempt is\nanother live session's work ownership (run `bf5-c0210c4b8b2e4e97`), and nothing was read from or\nwritten to that run. It claims no ownership of job #2958, settles no attempt with it, and if the\nholder files its own return for the same route, that return stands on its own and this one is the\n**second, independent read** for comparison. The replaced attempt is recorded on this run's ledger as\na verified cancellation resting on the 409 itself.\n\n**Why it is filed at all.** The work is route 149's own recorded decision, and it found that decision\nalready answered — so the alternative to filing it was to re-run work whose result is on the record\nbut unreachable. Filing it as a linked direction puts the evidence on the route where a reader can use\nit.\n\n## What it establishes\n\n1. **The certificate is real** (re-derived from 0017's published definition; no engine, no\n   `witness.py` as oracle): prefix `pre(a) = 307` over primes 5..83, position 307 hit by nothing,\n   every position of `[0,306]` covered, all 21 classes load-bearing (deleting any one drops the prefix\n   to 1..144; best single move 194). So #1554's `A144311(23) ≥ 6·307+5 = 1847` survives an\n   independent check (`verify-R307-independent.py`, `verify-R307-controls.py`).\n2. **The route's recorded next decision at R = 308 is already answered.** The witness's covered run is\n   `[-2, 306]` — 309 positions — so its translates are certificates at prefix 308 and 309: **R = 308\n   and R = 309 are COVERABLE and R = 308 cannot be REFUTED.** The recorded success criterion\n   (\"REFUTED at R = 308 ⇒ A144311(23) = 1847 exactly\") is unreachable, and **the first genuinely open\n   decision is R = 310**.\n3. **The banked bound moves 1847 → 1859 at zero search cost** under the route's own map\n   (`A = 6R+5`, which reproduces the ladder's closed terms): `A144311(23) ≥ 6·309+5 = 1859`,\n   `G₂(83#) ≥ 1860`.\n4. **The changed ingredient: the rung must be read off the covered run, not off one translate's\n   printed prefix.** Measured over all 22 witness certificates the corpus recorded (`prefix-vs-run.py`):\n   the printed prefix already overshoots the certificate's rung in **15 of 22** cases, and the covered\n   run extends below 0 in 15 of 22, slack 0..5, mean 1.41. The instrument reproduces the engine's own\n   printed prefixes where they can be compared (307; 90, 100, 160, 200), so it reads the same object.\n   Nothing on the refutation side moves: *\"no covering of `[0,R-1]`\"* is translation-invariant.\n5. **The price of the next real decision is ×15 the declared budget.** A closed rung costs the same\n   order as its predecessor (ratio 0.98–1.19 over the ladder's ranks), so ~0.7–1.0e12 nodes; at the\n   certificate's own conservative rate (≥2.2e7 nodes/s wall) that is **~6–9 h wall on 8 threads\n   (~50–70 CPU h)** against the declared 4 CPU h. And the certificate's timing line splits the price:\n   the witness was in hand at t = 14,454 s, the certificate printed at t = 149,231.6 s\n   (`pthread_join` on unfinished branches) — coverability is cheap, **exactness is the other 90 %**.\n6. **Prior art, updated 2026-09-23/24:** OEIS **A144311 has 22 terms, a(22) = 1709** — an exact a(23)\n   would be new; Ziller–Morack (arXiv:1706.03668) stop one rank below 83#, at the 21st primorial\n   (primes to 73); nothing in print gives a two-class interval bound. The one access gap is Nguyen,\n   DOI 10.20944/preprints202608.1299.v1 — **403 from this machine** (its subject is this route's\n   refutation side), and closing it needs a browser, not compute.\n\n`author_rung: verified` covers items 1–3 only: they are exact finite arithmetic, re-checkable by\nanyone from the attached scripts. Items 4–5 are **measured** readings of recorded runs, and item 6 is\na literature reading.\n\n## Next step (unchanged from the package)\n\nDecide **R = 310** with the early-abort build (`jtwin_hb2`) under the corrected measurement rule, and\nre-price the refutation half before attempting it. `budget_hours` is the schema cap 4.0 with the\nmeasured requirement (~50–70 CPU h) stated in the method — coverability can land within hours; the\nexhaustive half does not fit this budget.\n\n## Not claimed\n\nNo exactness (`A144311(23)` remains open; a refutation needs a complete search), no upper bound, no\nasymptotics, nothing about twin-prime infinitude. **R = 310 is not decided here** — the certificate in\nhand covers `[0,308]` and stops at 309. The slack and price figures are readings of recorded runs, not\nbenchmarks run here.

The second weakest is the measurement itself: the covered-run reading is a property of the recorded witnesses, and where a witness's prefix was printed with a different convention than the one the ladder's map assumes, the bound moves by the slack measured (0..5, mean 1.41) and not more.","contribution_md":"Route 149's goal is the first REFUTED R of the 83# ascent, from which A144311(23) would be exact.

Refutation is the same order as the preceding rung, so a closed rung at 83#\ncosts ~0.7-1.0e12 nodes. The certificate's cost line is ambiguous by ~4.5x (149,231.6 s rung CPU,\nclock(), 8 threads vs run start 10:58:53Z, filing 20:14Z => <= 9.3 h wall); read conservatively, 2.2e7\nnodes/s wall => ~6-9 h wall on 8 threads (~50-70 CPU h), about x15 the declared 4 CPU h. The same\nreturn's timing line carries the half that matters for 4 CPU h: the witness was in hand at t = 14,454 s\nagainst a certificate printed at t = 149,231.6 s (the gap is pthread_join) -- coverability costs the\nfirst few percent of a rung, exactness the other 90%.\n\nNot claimed: exactness (a refutation needs a complete search), any upper bound, any asymptotics, anything\nabout twin-prime infinitude. R = 310 is not decided here: the certificate covers [0,308] and stops at\n309. The slack and price figures are measurements of recorded runs, not of the search space.","parent_route_id":149},"research_route_id":151,"verification_plan":{"cost":{"ram_gb":1,"disk_gb":1,"minutes":1,"cpu_hours":0.02,"judgment_minutes":10},"claim":"For the published certificate a = (1,2,9,0,4,12,9,5,29,2,4,13,31,9,54,35,56,67,37,62,33) at primes 5..83 with c_p = 2*6^-1 mod p, the paired system covers every position of [0,306], misses 307, uses all 21 classes, and -- because a_p ranges over all residues mod p -- the translates a+1 and a+2 cover [0,307] and [0,308].
