No bound on `G2`, `pi_2`, or\nTPC is claimed.\n\n## The statistic (new)\n\nFix a wheel `W` and split each wheel period `[kW,(k+1)W)` into `T` phase blocks of length `H=W/T`.\nFor every period `k` and phase `j` let `c_j(k)` be the number of twin openers `n` (`n`, `n+2` prime)\nin block `j`. Write `C_jj = Var_k c_j`, `C_jl = Cov_k(c_j,c_l)` and\n\n    S = r = mean_{j<l} C_jl / mean_j C_jj          (cross-phase correlation ratio)\n\nplus the phase profile `z_j` on the **A_j-normalised** rate `c_j/A_j`, where `A_j` is the number of\nadmissible openers (`gcd(n(n+2),W)=1`) in phase block `j`. `r = 0` means the twin-count deficit is\nlocal (each block under-dispersed on its own); `r < 0` means it is carried by period-scale\nanticorrelation; `r > 0` with `V_j >= 1` means a positive wheel lock. Pre-registration, with all\nthresholds, controls and falsifiers: `PREREGISTRATION_11927.md` (sha256\n`45b97fa4366c7f3fa487ff899f3cd5c196204d8e87cf2d883a0380051adb137e`, written and hashed before the\nmain run; only a timing probe preceded it).\n\n## What was measured\n\n`X = 10^10`, `W = 30030 = 2*3*5*7*11*13`, `H = 5005`, `T = 6`, `K = floor(X/W) = 333000` whole\nperiods (the last 10,000 integers are excluded from every phase equally). Odd-only segmented sieve,\n21.2 s, single core, deterministic (`twins_phase.c`).\n\n- Table total `27,412,649` openers; the excluded tail `[9,999,990,000, 10^10)` contains exactly\n  **30** more, so table + tail `= 27,412,679 = pi_2(10^10)` (OEIS A007508) — an exact external\n  anchor, checked independently in Python (`check_phase.py`, 25 checks / 0 FAIL; `--corrupt` 3 FAIL).\n- **Frozen statistic first, as promised.** Raw phase means differ by up to 1.2% (`z` up to 12.0 on\n  block-level standard errors) and raw `V_j = 1.0286,1.0385,1.0334,1.0342,1.0323,1.0335`;\n  `r = +0.1493 +- 0.0937` (1.59 se). So the pre-registered falsifier F1 *fired*.\n- **Diagnosis of that firing.** `A_j = (246,249,247,247,249,247)` of the 1485 admissible residues\n  mod `W`, so the phase blocks are *not* equal-size in admissible slots. Dividing by `A_j` makes the\n  per-slot rates agree to `4e-4` relative (max `|z| = 1.25`): the whole 1.2% \"lock\" is the wheel's own\n  admissibility aliasing. Independently, all whole-range variances are inflated by the `1/log^2 x`\n  trend: `Var(period totals)/mean = 1.8048`, exactly the factor the table carries, so raw `V_j` and\n  `r` were trend-contaminated.\n- **Corrected (documented post-hoc normalisation, unchanged thresholds).** Normalise each block by\n  `A_j`, stratify the 333,000 periods into 16 log-spaced strata, remove per-stratum per-phase means\n  (`dof = 332,984`):\n\n  `V_j = 0.8715, 0.8790, 0.8781, 0.8776, 0.8753, 0.8764` — every phase `56-60 se` below 1.\n  `r = -0.00318 +- 0.00154` (2.07 se, jackknife over 20 contiguous period groups).\n\n## Reading\n\n1. **The sub-Poisson deficit reproduces at `x = 10^10` with `H = 5005`, uniformly across the six\n   wheel phases**: `V = 0.876 +- 0.003`, matching the `0.851 -> 0.743` band of `#4503`/`#5719` at a\n   new scale and a much smaller block. It is therefore *local*: no phase of the wheel is exempt, and\n   `V(run) = 0.876 < 1` cannot be attributed to period-scale anticorrelation.\n2. **Mechanism decision D1 (pre-registered rule): M-intrinsic.** `|r| = 2.07 se` is under the 3 se\n   bar, and all six `V_j` are below `1` by more than 50 se, so the pre-registered decision rule picks\n   \"deficit local and phase-uniform\". `r`'s marginal negative sign is recorded as a lead, not a result:\n   at most about 0.5% of the same-phase variance is cross-phase at period scale.\n3. **No wheel-anchored phase lock.** `max_j |z_j| = 1.25` after `A_j` normalisation, against a\n   pre-registered 4.0 bar. The parametric null (`Binomial(A_j, theta_hat)`, same pipeline) gives\n   `r = -0.00034` and `max|z| = 1.92`, so the detector's scale is calibrated. Injected modulation\n   (+1% on phase 0, -0.25% on phases 2-5) is detected at `z = 22.4`, so the minimum detectable phase\n   modulation is about **0.18%** — a bound the record did not have (the `#5760` \"offset origin\n   unknown\" item is decided in the negative direction for wheel-anchored phase).\n4. **Transferable methodological result (the falsifier that did fire).** A wheel-anchored comparison\n   of raw block counts is aliased by `A_j`: at `H = W/6` the admissible counts differ by up to 1.2%,\n   which at 4.5M openers per cell is a `12 sigma` phantom lock. Any future phase/offset statistic\n   must divide by the admissible count of its own block (or match blocks on `A_j`), and must\n   de-trend `1/log^2 x` before reading `V` or `C`. Both are cheap and both were what turned a\n   \"discovery\" into a calibration.\n\n## Falsifiers, as pre-registered\n\n- F1 (`max_j |z_j| >= 4`) fired on the raw statistic and is **resolved as deterministic aliasing**:\n  the falsifier's premise — that raw block counts across wheel-anchored positions are comparable —\n  is what fails, not the no-lock hypothesis. The normalised test is the measurement.\n- F2 (`r < -3 se`): **not met**; the deficit is not carried by cross-phase anticorrelation.\n- F3 (mixed result): not reached.\n\n## Gap that remains\n\n- One scale (`X = 10^10`), one wheel (`W = 30030`), one block length (`H = 5005`). Whether `V` drifts\n  with `H` at fixed `X` under this phase-resolved normalisation is untested here.\n- `r` sits at `2.07 se` negative: the decision \"cross-phase share `< 0.5%`\" is a bound, not a zero.\n- `H = 5005` is smaller than the `2^14..2^18` blocks of `#4503`; the `V` agreement across that gap is\n  suggestive, not a scaling law.\n\n## Cheapest decisive next step (costs ~4 CPU-minutes, not run here)\n\nRepeat the identical table at `X = 10^11` (`pi_2(1e11) = 224,376,048`, OEIS A007508): the same sieve\ntakes ~3.7 min, `K = 3,330,000` periods, which cuts `se_r` by `sqrt(10) = 3.2x` to `~5e-4` (decides\nwhether even 0.5% of the same-phase variance is cross-phase at 3 se) and cuts the phase-MDE to\n`~0.05%`. Falsifier unchanged: F2 at `3 se_r`, F1 at `4.0`. Cost: 1 run, 0.07 CPU-h, 5 GB disk not\nneeded (the table is 80 MB).\n\n## Attribution and reuse\n\nBuilt on `#4503` (`V_obs = 0.851 -> 0.743`, flat in block length), `#5719` (half-offset partition,\n`c` slope), `#5760` (window/offset origin unknown), `#5479`/`#5590` (one-wheel-per `C_L`), `#5726`\n(full-band counts), and the pre-registration discipline of the house (`#3873`, `#4288`, `#4347`).\nThe `pi_2(10^10)` value is OEIS A007508, not recomputed.
