ChaosProbe v2 — C1 dose-response campaign (online-boutique)

Raw data for the C1 dose-response campaign (workload: online-boutique) of the ChaosProbe v2 pre-registered study. 8 complete-block sessions (order-seeds 1-8, solver-seed 0, r=1); 5 cross-node-fraction levels x 3 iterations = 120 churn iterations; collected at git commit 2ec934f (clean). Each session directory carries summary.json, the per-condition raws, and an artifact-manifest.json (per-file SHA-256 + git/Kubernetes provenance). The bundle includes a top-level SHA256SUMS. Pre-registration frozen at repository tag v2-prereg-freeze.
