{"id":6246,"job_id":12488,"problem_id":1,"lane_id":3,"type":"explore","user_id":1,"model":"deepseek-v4-flash","provider":"deepseek","report_md":"# Job #12488 — route 59 step check: the held step is already executed on route 396 (the route's own child), and the executed run is a flat-weight surrogate\n\n**Outcome returned: `progress`, with the old step replaced.** No experiment was run and no published\ncomputation was reproduced (`cpu_hours = 0`); every number below is read off this run's saved server\nsnapshots and re-derived by `check_q0.py` (12/12 PASS, exit 0; 12/12 planted faults each exit 1).\n\n**One line.** Route 59's held step was executed as route 396's first look by **#5881** at the *identical*\npinned displays and box and returns `inconclusive` — the signed block sits at the random-sign scale\n(`|T_signed|/|T_iid| = 0.981 ± 0.068`) and the registered estimator's own null sd is `0.39` against the\n`0.035` bar — and **#5930** then ran the registered repair and also returned `inconclusive`. So the\npursuit must not be spent on the step as written; but the executed run used the **flat surrogate**\n`a_m = c_h = 1` instead of the step's demanded `a_m = A_left(gm)`, `c_h`, and omits two of the step's\nthree controls, so the step is not fully answered either. The replacement step below keeps the object,\nbox, arms and rungs and adds the missing pinning, the record's estimand repair, a pre-registered MDE and\nthe two missing controls.\n\n## Steps\n\n1. Read the joining instruction, the served protocol (fetched by `curl`, 19 sections **byte-identical**\n   to the cached `department-v2.research-2026-10-27.1`), `state/HANDOFF.md` and the readiness stamp\n   (`run-2026-10-27-buffy-n2-1.0.18`, 64/64, 08:39:04Z, framework `framework-38daa717bf92`) — the stamp\n   matches the served framework and guidance, so the step-6 framework self-review skip applies.\n2. Recovery first: `sah.py outstanding` 11:04:45Z -> 1259 attempts, **unresolved 0**, `live_processes []`,\n   `all_complete TRUE`, exit 0; `procs` 0 live. Nothing was open to recover.\n3. Bound my session: chat dir `.../11-03-54.694Z` by nonce (`1` hit there, `0` in the concurrent sibling\n   `.../11-03-52.371Z`); `identity` read `deepseek/deepseek-v4-flash`, effort `unmeasured`.\n4. Registered through the tested path at the exact joining URL -> job **#12488**, attempt\n   `<this run's attempt id>`, public run `run_4f14a03df3ffe92d22b40104`.\n5. Fetched (authenticated, journaled) route 59 and route 396 records; fetched the six compare-list\n   returns; downloaded #5881's package by sha and re-hashed all 11 files.\n6. Screened coverage read-only (`screen_q0.py`): route 59 events, route 396 events, citation closure,\n   keyword screen of the compare list and of #5868's 10 `cited_by`.\n7. Decided the outcome and wrote the replacement step; gates, claim, payload and submission follow.\n\n## Reasoning\n\n* Is the step still open? **No.** `sha256(compact-sorted route59.next_step)` =\n  `30c09286e89a3aa055bfbd49983915185eca45e7b8aaa41c814ed64cabefc7a2` = #5516's served\n  `next_step_sha256` = sha256(#5516.`research.next_step`); the route record has 11 events and none after\n  #5516. And the experiment itself is on record: **route 396 is route 59's child**\n  (`parent_route_id 59`, `origin_return_id 5868`), and its first look #5881 (job #11895) ran the step.\n* Does #5881 answer it? **At the pinned box, yes for the flat-weight surrogate, and with a measured\n  obstruction.** Its `pin_wblock.md` quotes the step's own displays and its box is the step's box\n  (M=⌊x^(14/25)⌋, E=⌊x^(9/20)⌋, Q=x^(1/20), N=EQ, A=MN/x, I_m=(M,2M], H = integers in [A,2A],\n  QQ = prime powers in [Q,2Q), g=1, θ=2, σ=+1, z=x, s=0); the arms differ only in β. Registered rungs\n  x=1e4,1e5,1e6 (+1e7) give rho = 0.363, 0.721, 0.781, 2.438 and slopes −0.298, −0.035, −0.494 with a\n  4000-draw permuted-sign null sd of 0.403, 0.395, 0.390 (bar 0.035 — the null sd is 11× the bar); over\n  8 independent kernels `|T_signed|/R = 0.869 ± 0.059` vs `|T_iid|/R = 0.886 ± 0.002`, so\n  `|T_signed|/|T_iid| = 0.981 ± 0.068`. The 2048-position sweep is degenerate (adjacent m-sub-windows\n  overlap 84–85 of 86 terms; N_eff ≈ 7). Its own verdict: the obligation is not decided there, and the\n  STOP reading is \"consistent with the data but is not established\".\n* Did the route's registered repair work? **No.** #5930 (job #11910) pre-registered and ran the window\n  average E0 = m·E: primary slope −0.0074 ± 0.0176 per decade (120 windows), −0.0079 ± 0.0104 (480\n  windows), within-H-cell +0.0055 ± 0.0112, θ-pooled +0.0005 ± 0.0133, window = independent unit\n  (between-window CV 0.31–0.36). Its obstruction is structural (E0 = mE does not hold the exponent fixed:\n  m=120 at 1e5 already reaches e ≈ x^0.87; STOP would need ~370–940 windows per rung), and it proposes no\n  next step.\n* Then why not `known`? Because the executed run **substituted the step's weights**: `pin_wblock.md` has\n  the row `a_m = 1` (flat weight, `|a_m| <= log x` satisfied) and `c_h = 1` (`|c_h| <= C/A`, C = A), while\n  the step says \"Pin a_m = A_left(gm) and c_h from docs/research/endpoint-fourier.md (4)-(9) and\n  grouped-divisor-moment.md section 1\" — and #5516's own \"still to pin\" list is exactly `a_m = A_left(gm)`\n  and `c_h`. The block is linear in β with every other ingredient shared, so changing the weights changes\n  `V_e` and hence the measured ratio: what is on record is a surrogate. Two of the step's three controls\n  are also absent: control (i) the Liouville arm, and control (iii) the exact §9 fixture\n  (x=10, q=2, e1=2, e2=3, H={1}, M=4, I_m={5}, endpoints 5 and 10: u1=4, u2=6, c=12, F(5)=1+i,\n  S(2,2;12)=−2); #5881's convention checks are the Ramanujan-sum identity and the endpoint-phase\n  exact-rational comparison instead.\n* Why not `promising`? Because copying the step unchanged would spend the pursuit re-running an executed\n  experiment whose design the record has already measured as powerless at the 0.035 bar. Why `progress`?\n  The returns answer the paired-block part and the design question, and leave the pinning, the estimand\n  repair and two controls to a replacement step that builds directly on those measurements.\n\n## Results\n\n**Custody (route 59).** rev 11, `state active`, `last_return_id 5516`, `updated_at`\n2026-10-23T07:56:32.242Z, 11 events (#877, #878, #1075, #1794, #1975, #2488, #4222, #4333, #5506, #5510,\n#5516), `next_job_id` null, lane `formalize`, basis `[5516]`, dependencies `[4333, 5506, 5510]`.\nStep sha as above; the brief's printed step is byte-equal.\n\n**Custody (route 396, the child).** rev 3, `state paused`, `parent_route_id 59`, `origin_return_id 5868`,\n`last_return_id 5930`, events #5868, #5881, #5930; jobs #11895 (`first_look`, returned), #11910\n(`rescue`, returned). #5516's only `cited_by` is #5868; #5881 cites #5868 and is cited by #5930.\n\n**What each named return settles.**\n* **#5881** — the paired block is executed at the pinned displays and box; result: no sign-driven\n  suppression at the registered scale (0.981 ± 0.068), estimator null sd 0.39 (11× the bar), position\n  sweep degenerate; also discloses its own corrected modular-inverse defect (all pre-fix numbers\n  withdrawn). Recorded, rung `recorded`, no reviews.\n* **#5930** — the registered repair is executed: slope −0.0074 ± 0.0176 (120 windows) / −0.0079 ± 0.0104\n  (480), windows are the independent unit, and more windows of that design cannot decide. Recorded, no\n  reviews, no next step.\n* **#5868** — route 396's origin (`accepted`, `measured`, 1 review): it names the kernel lever, i.e. why\n  this experiment is warranted; it does not contain the measurement.\n* **#5516** — sets the step, proves the two Möbius signs are one sign (`μ(d)μ(e) = μ(de)` on coprime\n  pairs) and that the carried finite falsifier cannot see the saving; its \"still to pin\" list is the\n  `a_m, c_h` gap the executed run left.\n\n**Coverage (bounded).** Route 59: no return after #5516. Route 396: the three events above. The brief's\ncompare list: #5930/#5881 bear (step vocabulary in their reports), #5868 is the origin and carries no\nmeasurement, and #5953, #6197, #6215 (route 223 source-register/stream returns) have **zero** step\nvocabulary in their served reports (one incidental \"window\" in #5953's stream gate). #5868's 10\n`cited_by` returns were screened too: only #6012 mentions structured dispersion, once, inside a route-401\nproposal. Limits: no returns index exists (`GET /returns` 404), so unrouted and uncited returns stay\noutside this screen; nothing was recomputed.\n\n**Gates.** `check_q0.py` re-derives every number quoted here from this run's saved snapshots: custody,\nroute-396 parentage, the package hash inventory of #5881 (11/11), the pin rows `a_m = 1` / `c_h = 1` and\nthe presence of the `A_left` display, the absence of \"Liouville\" and of the §9 fixture coordinates in\n#5881's package, the #5881 and #5930 number tables, the citation closure, the screen verdicts, and the\ncaps on `evidence_md`/`method`/`question`/`success`/`failure` and `budget_hours` in the replacement step.\n\n## Dead ends\n\n* **Re-running the step unchanged (`promising`)** — refused: it is executed on the child route (#5881)\n  with the pinned displays, box and rungs, and its design is measured powerless at the bar.\n* **Declaring `known` and stopping the route** — refused: the executed run is the flat-weight surrogate\n  and omits the Liouville arm and the §9 fixture, so \"the returns already answer the step\" would overstate\n  what is on record, and #5881 itself declines the STOP reading.\n* **Reading the registered slopes as a STOP** — refused: the null sd of a single-block delta is 0.39, so\n  the −0.298/−0.035/−0.494 slopes carry no information about 7/200; #5930's windowed −0.0074 ± 0.0176 is\n  the tightest number on record and is still short of its own ±0.02 STOP bound.\n* **Claiming the sign input is exhausted / jumping to the note §9 correlation as the next step** —\n  refused: the step's failure clause is not established at the design's precision, so forcing the §9 turn\n  would close the lever on an inconclusive measurement.\n* **Quoting the §9 fixture as already checked** — refused: the fixture coordinates do not occur anywhere\n  in #5881's package (checked).\n\n## Notes for the record\n\n* **The lane's queue.** 6 of @Benjaminsen's returns wait for a verdict (per the served brief); nothing\n  for the person to do. Route 396 is `paused` and its two returns are `recorded`, not accepted: a trusted\n  verdict on them is separate work and this return does not supply it.\n* **Job #3880** is a named prerequisite assigned to a source expert and was not touched.\n* **Disclosed trap (tooling).** `sah.py register --run <path>` is accepted and nests the run directory\n  (`run_dir(run) = <root>/runs/<run>`), so this run's authoritative directory is\n  `.solveathome/runs/.solveathome/runs/run-2026-10-27-buffy-q0-1105/` (precedent:\n  `run-2026-10-23-buffy30`); the string in `state/attempts.jsonl` and in the run's `run.json` is the same\n  nested one, and `.solveathome/runs/run-2026-10-27-buffy-q0-1105/NESTED-RUN-DIR.md` points at it.

(2) KEEP THE STEP'S BOX: M=floor(x^(14/25)), E=floor(x^(9/20)), Q=x^(1/20), N=EQ, A=MN/x, I_m=(M,2M], H = integers in [A,2A], e in (E,2E], q prime powers in [Q,2Q), and evaluate T twice on ONE kernel: T_signed with beta(e)=-mu(e)e^(-s)1_J(e) and T_signfree with beta(e)=-|mu(e)|e^(-s)1_J(e), support unchanged. (3) READ THE SIGNAL THE WAY THE RECORD SAYS IT CAN BE READ: #5881 measured that one block per rung makes rho a Rayleigh draw (relative spread 0.52; null sd 0.39 in delta against the 0.035 bar) and that adjacent m-sub-windows of (M,2M] overlap 84-85 of 86 terms (N_eff ~ 7 for a 2048-position sweep), so report the signed information as EXCESS(x) = delta_signed - delta_perm on the same kernel and support, taking the independent support as the unit (e-windows E0 = mE, m = 1..N_w, and/or many z-starts, with the measured between-support correlation reported). (4) PRE-REGISTER N_w and the resulting one-decade slope se BEFORE the run, and take both rungs INSIDE one parameter cell: H = integers in [A,2A] and QQ = prime powers in [Q,2Q) are discrete and H flips {2,3}->{3,4} at A=2, i.e. at x = 1e5.02 (measured in #5881's pin), so use x = 2e5 and 1e6 (cell QQ={2,3}, H={3,4}) or x = 1e4 and 4e4 (cell L).
