Relaunched with sandbox\n  disabled — healthy (main PID 23300 + 14 workers). ETA ~1.5–2 h.\n- LESSON: detached multiprocessing jobs must be launched with the\n  sandbox disabled (session-004 machinery note amended).\n- **Run still in progress at session stop** (user called stop). If the\n  machine shuts down, rerun: E-015 script with --force (crash-safe:\n  outputs written only at completion).\n\n### A3 (Q-S3c): E-016 created, run, V3 fails — rich diagnostic findings\n- E-016-herglotz-fine-structure.py: ρ_W(y) = −(1/π) Im(W′/W)(iy) via\n  ANALYTIC Galerkin z-derivative (no finite differences) at θ=π and\n  θ=0 control, a ∈ {4,6,8,10}, vs ρ_F(y) = (1/π)[2/y + ξ′/ξ − ξ″/ξ′].\n- Bugs found and fixed during bring-up: (i) hat-derivative missing a\n  factor h; (ii) ξ(1) removable pole at y=0.5 (mp.zeta(1) raises) —\n  exact value ½ supplied; (iii) flint cross-check NaN at s=1 (arb pole)\n  — point dropped; (iv) |W|-minima zero finder with brent polish was\n  noisy at large z (spurious brackets where |W| grazes) — replaced by\n  exact real-gauge sign-change + brentq (c=1 exactly ⟹ W(iy-real) pure\n  imaginary, g(z)=z ImV−ReV).\n- Results: V1 (plateau = a/π, ≤0.15%) PASS; V2 (ρ_F vs finite-diff of\n  log|F|, 1.3e-8) PASS; V4 (mirror symmetry) PASS; xi vs flint 8.8e-17.\n  **V3 (Poisson reconstruction from located zeros + EM lattice tail vs\n  analytic ρ_W) FAILS: rel ~0.3 at all a.**\n- Debug findings (analysis in D-024):\n  * θ=π zeros ARE real (sign changes confirmed) — Thm 1.5 survives\n    Galerkin at θ=π.\n  * z₁(θ=π)·a ≈ 4.504, 4.499, 4.497, 4.496 at a=4,6,8,10 — a stiff\n    ~4.5/a law, NOT the rigid half-shift π/2a. No θ=π zero in (0,π/a).\n  * ρ_W − recon: +a/π at y=0.5, monotone decrease, zero crossing\n    y≈7, −0.99 at y=20 (a=4) — structure consistent with nonzero\n    Im κ (exponential-factor gauge) and/or missing/extra zeros; root\n    cause NOT pinned at stop time.\n  * d_pi ≈ d_zero (θ=π marginally WORSE on raw L2 over [1,20]:\n    1.2201 vs 1.2165 at a=4) — raw L2 is plateau-dominated; the\n    informative metric must weight small y.\n- Session interrupted 3× by network dropouts (no state loss); user\n  stopped during V3 root-causing.\n\n## Decisions\n- E-016 kept as experiment-with-failed-check (CSV/JSON written with\n  checks recorded honestly); V3 root cause = first task next session.\n\n## Next session\n1. Finish V3 root-cause (D-024 §4 lists the three candidates:\n   Im κ ≠ 0 measurable via W′(0)/W(0); low-zero bookkeeping vs θ=0;\n   large-z zero-finder noise contaminating recon).\n2.
