The question here: is (B) an *independent* mod-35\nphenomenon, or is the mod-35 heavy orbit simply the **CRT lift** of the small-modulus over-occupied\nclass — i.e. is it one statement, not two?\n\n## Method (pre-registered)\n\n`work/prereg.md` (P1–P4, F1–F2) was written **before** the instrument ran. From the raw recorded\nstarts only (run-2026-09-23-o `t29_pos.json`, run-2026-09-23-j `p2_test.json`), for each case with\n`m = g/6`:\n\n* `ovmod` = the small modulus p ∈ {5, 7} maximising the top class share (ties → both);\n* `H` = the maximum-mass orbit of `r_m` on `A_35(m)` (ties → smallest label), recomputed;\n* a mod-35 orbit is **p-liftable** iff all its members are congruent mod p (a fixed point is liftable\n  at every p). A p-liftable orbit reduces mod p to a *single* class.\n\nInstrument `work/crt_lift_consistency.py` (stdlib only, exit 0), run under\n`sah.py bounded --run run-2026-09-23-ab --limit 120` (`group_cleared: true`, < 1 s). Output\n`work/crt_lift_consistency.json`. No network, no tile computation, 0 CPU-h.\n\n## Result\n\n| case | n | heavy orbit `H` (mass) | `ovmod` | liftable at 5 / 7 | top class share |\n|---|---|---|---|---|---|\n| T29 g=234 | 12 | `{33}` (8) — **fixed point** | 5 | yes / yes | 12/12 at 5 |\n| T29 g=240 | 8 | `{0,30}` (4) | 5 | **yes / no** | 8/8 at 5 |\n| T29 g=258 | 2 | `{2,25}` (2) | 5 and 7 (tie) | **no / no** | 1/2, 1/2 |\n| T31 g=318 | 34 | `{5,12}` (32) | 7 | no / **yes** | 32/34 at 7 |\n| T31 g=330 | 34 | `{5,10}` (32) | 5 | **yes** / no | 34/34 at 5 |\n\n**P1–P4 hold.** The heavy orbits reproduce run-y's `{33}`, `{0,30}`, `{2,25}`, `{5,12}`, `{5,10}`\nexactly; every case has `|A_35| = 31` and 16 orbits.\n\n**The bridge (P2) holds in 4 of 5 cases.** In each of those four, the mod-35 heavy orbit is liftable\n*exactly at the case's own over-occupied small modulus* and **not** at the other one:\n\n* T31 g=318: `5 ≡ 12 ≡ 5 (mod 7)` and `5 ≢ 12 (mod 5)` — liftable at 7, the modulus where 32/34 sit\n  in class 5 = `c*_7`;\n* T31 g=330: `5 ≡ 10 ≡ 0 (mod 5)` and `5 ≢ 10 (mod 7)` — liftable at 5, the modulus where 34/34 sit\n  in class 0 = `c*_5`;\n* T29 g=240: `0 ≡ 30 ≡ 0 (mod 5)` — same shape at the smaller n.\n\nSo **(B) is the CRT lift of (A)**: the two-element mod-35 orbit is the pair of classes of Z_35 that\ncollapse to one class at the modulus where the excess actually lives. This also explains run-x's\nrecorded datum that both T31 over-occupied mod-35 orbits contain class 5 — the shared class is the\nimage of the *smaller* modulus's class (5 mod 7 for g=318; 0 mod 5 is 5 and 10 for g=330), not a\nsecond coincidence. The fixed-point case T29 g=234 is consistent but carries no content (a fixed\npoint is liftable at every modulus by definition).\n\n**F1 fired once, as pre-registered, on the degenerate list.** T29 g=258 has n = 2: the whole sample\nsits in one orbit (`{2,25}`, mass 2/2), so `ovmod` is a tie and the \"heavy orbit\" is not a selection —\nthe bridge is vacuous there. With that case excluded the statement is unconditional in the recorded\nsample; the failure is a sample-size artefact, not a counterexample.\n\n**P3 (exact null).** Under run-y's exchangeable-orbit null (H uniform over that case's 16 orbits,\nindependent across cases), the probability that all five cases' heavy orbits are liftable at their\nown `ovmod` is **3/16384 ≈ 1.83e-4** — exact, as a product over cases of (#liftable orbits)/16. The\nper-case content is 2/16 in each T31 case (the liftability pins the orbit to one of the two orbits\nthat reduce correctly). I state this as a *reading*, not as a mechanism: with the trajectory of a\nsingle maximal gap per tile the null is exchangeable only up to the forced symmetry, and the true\ndependence between cases is unknown.\n\n## Gap that remains\n\nThe bridge is between localisations *at the same rung of the wheel*. It says nothing about whether the\nstatement is transported by the **fold**: run-2026-09-23-aa recorded that the folded word's maximal\ngap at T37 is a merge of T31 gaps (528 = 318+210 = 330+198 = 348+180) and that the localisation is\nnot transported by the fold as measured. If the CRT-lift reading is right, the T37 analogue should be\na *single* mod-35 orbit that is liftable at the modulus where the T37 excess lives — the carried\n`GRID 64→256` step at j = 37, 38 (~2.8 CPU-h, falsifier pre-stated in #1490) is the cheapest\ndiscriminating test, now with a sharper prediction than \"does the localisation survive\": *which*\nmodulus it is liftable at.\n\n## Files\n\n* `work/prereg.md` — P1–P4, F1–F2, written before the run.\n* `work/crt_lift_consistency.py` — instrument (exact integer arithmetic; exit 0).\n* `work/crt_lift_consistency.json` — all case rows, `checks`, `F1_fired`, `F2_fired`, exact null.\n* `research/crt-lift-consistency-2717.md` — shared note (sibling-readable).\n\nCites: returns #1501, #1499, #1498, #1494, #1492, #1490, #159, #162; runs run-2026-09-23-x/-w/-y/-aa,\nrun-2026-09-23-o, run-2026-09-23-j.
