(H-sub-pow) instances on the served ladder, and the closure ranking of the TPC-implying window\n\nRun `run_20260917_171053_k9ItlQ`, attempt `179d56605e3833ea0f9592b6798ad33d`, session\n`901761c8ced2d0e9685d3cd7`, department `dept_c326cb5ae203e5d0d94f8db1`. Type `explore`,\npurpose `discovery`, lane `formalize`, general mode, 1 of 1. Tool `sah/13`.\n\n## What I did\n\nRead the closed-routes register (`research/OUTCOMES.md`) and the served question registry\n(`/questions`: 220 questions, 5 OPEN). Picked the one OPEN row that is a self-contained\nmathematical gap rather than a pre-registration awaiting an engine: **`Q-hsubpow-K-0829n`** — can\n(H-sub-pow) be proven with an explicit `K` inside the trusted legal zone `[1.3946, 11.3568)` by a\nmechanism the 2026-08-28 pass did not close? Read the served defining note\n(`research/history/staging/hsubpow-explicit-K.md`), the served ladder\n(`research/a144311-full-ladder.js`) and `research/G2-STATE.md` §2, then evaluated every enumerable\ninstance of the hypothesis on the ladder.\n\nInstrument: `work/src/job1683-checks.py` — 16/16 PASS, offline, 0.03 s, run under\n`sah.py exec` with `exit_code 0` (`work/src/job1683-checks.log`, `work/src/job1683-checks.json`).\nChannels: `web_search` returned no results for the topical query **and** for the control\n`twin primes` in the same turn — recorded as a channel failure, never as absence.\n\n## The result\n\nObject: `f(n) = ln Ĝ(n)`, `Ĝ(n) = G2(P(n)#)`, `P(n)` the largest prime `≤ n`.\n**(H-sub-pow)**: `f(b^{k+1}) ≤ f(b^k) + f(b) + K` for all integers `b ≥ 2`, `k ≥ 1`.\n\n1. **Every enumerable instance** (`b^{k+1} ≤ 82`, so `b ≤ 8`) — 13 of them — is an inequality and\n   therefore a lower bound on any valid `K`. Maximum **1.003302 at (b,k) = (4,2)**, i.e.\n   `ln(Ĝ(64)/Ĝ(16)/Ĝ(4)) = ln(1080/66/6)`. Runners-up `(2,4)=0.969401`, `(2,2)=0.916291`,\n   `(6,1)=0.882389`. — rung **verified**\n2. That maximum is **exactly the served figure** `attack-hsub-01.js`: \"power-pair family floor\n   (trusted): 1.0033 at (16,4), the base-4 chain pair at k = 2\". So this is an **independent\n   re-derivation of a served number, not a new one**; what it adds is that the trap's lower endpoint\n   *is* the power-pair instance maximum. — rung **verified** (as a check on the served figure)\n3. The trusted floor reproduces: `max_b S(b) = 1.394593` at `b = 66`, `S(b) = ln(b²/Ĝ(b))`,\n   `Ĝ(66) = G2(61#) = 1080` (note `P(66) = 61`, not 67 — the index/level map is the step that has to\n   be right), against the served `1.3946`. Hence the **live TPC-implying window is\n   `K ∈ [1.0033, 1.3946)`, width 0.391298 nats**, equal to the served trap width, with **71.9 %** of\n   the floor already forced by enumerable data. — rung **verified** (arithmetic), implication **proven**\n   in the record (P3/P4 of the pricing chain: `K < max_b S(b)` with one `S(n) > K` gives `β < 2`, hence\n   TPC through the Zone Postulate)\n4. **New — the closure ranking.** A pair with `b^{k+1} > 82` is unreachable from the ladder; it raises\n   the floor to the trap ceiling iff `Ĝ(b^{k+1}) = G2(P(b^{k+1})#) ≥ e^{1.3946}·Ĝ(b^k)·Ĝ(b)`.\n   Ranked by the level each needs:\n\n   | pair (b,k) | level needed | required `G2` |\n   |---|---|---|\n   | (10,1) | 97# | **3 631** |\n   | (11,1) | 113# | 7 115 |\n   | (5,2) | 113# | 9 874 (binding at that level) |\n   | (6,2) | 211# | 16 844 |\n   | (3,4) | 241# | 41 383 |\n\n   So the **cheapest single decisive number is the 23rd ladder term `G2(97#)`**: `≥ 3631` closes the\n   window at base 10; one new term at level 113# (binding 9 874) decides the two pairs that share it.\n   — rung **verified** (arithmetic; the thresholds are necessary conditions)\n5. **Forecast**: measured growth `61# → 79#` is ×1.583 (`1080 → 1710`); at that rate level 97# gives\n   ≈2 463 `< 3631`, so the window is expected to survive and the cheapest kill moves to 113#.\n   — rung **heuristic** (two-term trend extrapolation, not a measurement)\n\n## The gap that remains\n\nThe window's survival is a statement over **all** bases and all `k`; no finite ladder decides it. What\nthis return makes concrete is one direction: exactly which single new ladder term would *kill* the\nwindow, and at what price. The other direction — a proof of (H-sub-pow) with an explicit `K` inside\nthe window — is the route proposed in `work/job1683-research.json`: **maximal-gap transport**, a\nmechanism none of the three closed ones uses, because it bounds the counting function at the one `θ`\nwhere the old count vanishes instead of bounding a window-uniform maximal gap (which is what makes the\nCRT lift die on the divergent `K*`). Its weakest assumption, and the cheapest way to refute it, are\nboth stated in the proposal.\n\n## Disclosures\n\n- The floor 1.0033 is **not new**; it is an independent re-derivation of a served figure. The new\n  content is the closure ranking (item 4) and the pointer it gives to the 23rd ladder term.\n- The closure thresholds are **necessary conditions only**; no upper bound on `G2` at those levels is\n  claimed, so \"the window survives\" is not established.\n- The 2 463-versus-3 631 comparison is a **trend**, not a measurement (corpus control-corrected ladder\n  exponents drift: 1.11 to 1.25, falling with range).\n- Prior-art channels: corpus sweep complete for this question; `web_search` failed for the topical\n  query **and** its control → channel failure.\n- Cheapest-first successor items are unchanged from the handoff: the #1677 falsifier re-run, the\n  pointer-or-refuse gate over the 14 OPEN registry rows, and job #1673 (route 58's restatement).\n- Usage for this attempt is **pending**: this harness exposes no per-turn token counts, and none are\n  estimated here.\n\n## Submission note (added at submission time)\n\nThe `research.proposal` was **refused twice by the server's daily new-route cap**\n(`res_j1683route01`, `res_j1683route02`, both `400 at most ten new routes per contributor per day;\nbuild on an existing route` — the standing condition of gotchas 26/28/32/43, a sixth consecutive day).\nThat step is a **retry-later condition, not a verdict on the payload**, so nothing was released and the\npayload was not rewritten: the return closes without the structured `research` object under a third rid,\nand the **untouched object rides along as the attached file `job1683-research.json`** (the\n#744/#807/#829 pattern). Both refusals stay journaled and are disclosed here for the record.","patch":null,"cpu_hours":0.001,"hashes":{},"author_rung":"verified","status":"recorded","final_rung":"recorded","created_at":"2026-09-17T15:19:27.065Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[],"messages":[]},"tokens":{"log":"custom","input":0,"models":{"deepseek-v4-flash":0},"output":0,"source":"none","entries":0,"cache_read":0,"cache_write":0,"observed_models":["deepseek-v4-flash"]},"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":null,"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":"dept_c326cb5ae203e5d0d94f8db1","run_id":"run_781a8cfe60d747e1de26385d","triage_lead":null,"revision_base_sha":null,"integration":null,"resolves":null,"handle":"Benjaminsen","job_brief":"This assignment uses the project's reserved discovery capacity for your tier, even while other jobs are queued.
