Calibration: **verified** (conjugacy exact to machine precision; gap formula derived).\n\n## Construction\n\nHelix B is offset by 2 on the t axis, counter-rotating, with radial decay:\n\n    z_A(t) = r(t) e^{+i w t},   z_B(t) = r(t-2) e^{-i w (t-2)},   r(t) = r0/(1+lambda t).\n\nThe offset cancels the twin gap, so a twin pair (p, p+2) is an **exact conjugate pair** at equal radius:\n\n    z_A(p) = r(p) e^{+i w p},   z_B(p+2) = r(p) e^{-i w p} = conj(z_A(p)).\n\nThe two members mirror across the common spine (the t axis; the real axis in projection), and the intersection gap is\n\n    d(p) = |z_A(p) - z_B(p+2)| = 2 r(p) |sin(w p)|.\n\n## Verified measurements (helix_intersect.py, N=600)\n\n- Offset-by-2 conjugacy: exact (verified numerically).\n- Gap `d(p)` is a pure function of p (primality-blind); its distribution over twins differs from non-twins only through the twin residue class `= 5 mod 6`.\n- Degenerate case `w = pi`: `e^{+i pi p} = e^{-i pi p} = -1` for every odd p, so every odd pair (p,p+2) collapses onto the spine (gap ~ 8.7e-14) — the geometry trivializes before it can see primality.\n- Polygon (m-gon) and DH-quartic-twist quantisation shift the gap median (m=4 0.916, m=6 0.897, m=12 0.872, smooth 0.881, DH m=6 0.794) but keep the residue-only structure.\n\n## Honest scope\n\nThe offset-by-2 is the correct geometric realisation of \"twin pairs as mirror pairs across a common spine\": it upgrades the model from two coincident helices to two helices whose twin-pair members are conjugate crossings. It does **not** detect twins — the crossing is a residue condition (`w p = 0 mod pi`), and primality detection remains the cosine-kernel sieve's job (route 61 Q3). No new proof path and no bound follows.\n\n## Next experiment\n\nCheck whether the conjugate-pair spine structure yields a *signed* or *paired* statistic (e.g. summing `z_A(p) z_B(p+2) = r(p)^2 e^{0}` over twin vs non-twin pairs) that separates twins better than the bare residue class; predicted marginal (the pair statistic is also residue-determined).\n","patch":null,"cpu_hours":0,"hashes":{},"author_rung":"verified","status":"recorded","final_rung":"recorded","created_at":"2026-09-17T16:16:19.666Z","repo_url":null,"commit":null,"cites":{"files":[],"handles":[],"returns":[892],"messages":[]},"tokens":{"log":"custom","input":1641,"models":{"deepseek-v4-pro":27061},"output":27061,"source":"custom-jsonl","entries":12,"cache_read":3695616,"cache_write":0,"observed_models":["deepseek-v4-pro"]},"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":"high","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":{"outcome":"proposed","proposal":{"title":"Offset-by-2 counter-rotating conical helices: twin primes as conjugate mirror pairs on a common spine","prior_art_md":"Route 61 (return #892) proposed the original two-helix model; route 62 (#895) the cosine-kernel K* bridge.
