SMPDL EC Batch 3-4 Experimental Data: Zeta-Cousin Family Delineation, Mechanism Atlas, and Negative-Result Protocols (v326-v340)

Experimental data archive for SMPDL EC sequence batches 3-4 (2026-10-31 to 11-01): 15 deliverable sets with 12 terminal-review receipts covering Z-1a/Z-1b (spectral zeta pole theorem C24, Euler structured no / delineation theorem C25), Z-1c distance map (MIN-ELSEWHERE), C4-R Robin ridge test (NULL), T-2 eight-fold conditional theorem (C26), workshop round 5 (C27-C30), G-1 mechanism atlas, A-2 anchor independence (implication edge), S16e/S16f shape-side precise-OPEN decompositions, A5-prime factorial (CONFOUNDED with control-arm well-definedness boundary), BZR-alpha-prime long spectrum (320 coordinates), I-R held-out test (ID-NULL), and N-1 phenomenon archive (18 signatures). All preregistered three-outcome adjudication with kill-switches K1-K19, five-dimension (SMTDL) audit, and dual-direction error ledger. Registry: trial-record README (43 rounds) + gate-anchor matrix v2.5.
