Status: Track C is now mapped and the first measurement is banked.\n\n**Where we stand in Track C:**\n- **D-014** — the 2026 landscape (Suzuki, Groskin, Kim et al., Connes) and our unoccupied niche: we hold the only *unconditional second-moment input*; they hold the truncation/certification language. The intersection is ours to exploit.\n- **E-006/D-015** — the positivity horizon is beyond float64's reach (floor ~1e-10 flat), and the truncation is genuinely ill-conditioned even at bandwidth 1. This validates Groskin's exact-arithmetic approach and gives the obstruction map a new quantitative entry.\n\n**Three options for the next sub-stage** (from D-015 §4):\n\n| Option | What it does | Type |\n|---|---|---|\n| **(a) E-007** (recommended) | Extended-precision (mpmath) floor measurement at small dimension — actually answers the horizon question: does λ_min decay superexponentially with support? | Numerical (~minutes) |\n| **(b) Q-3.4a** | Pen-and-paper: does our unconditional n₊ lower bound shrink Groskin's indeterminate zone [−B_T, 0)? | Analytic |\n| **(c) Task 3.2** | Li coefficients λ_n numerics toward n ~ 10⁵ — uses the zero table; different flavor | Numerical |\n\nWhich one?"}]
