docs/tutorials/sbi_nre_integration.ipynb using the deterministic configuration:
update Part 4b at lines 1477-1478, include the NRE sampler-health result at
lines 2142-2166, update Part 5b fidelity-check output at lines 2267-2276, and
include the analytical health result, comparison table, and posterior-fidelity
result at lines 2485-2507.
- Around line 2156-2157: Remove or revise the min_ess_bulk >= 400 assertion in
validate_sampling_health so the saved NRE result with z ess_bulk=359 does not
fail notebook execution; if retaining an ESS check, use a passing threshold or
regenerate the result to satisfy it.

2350-2355: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick winUse “analytical reference” consistently.
The section heading still calls this a “ground-truth posterior”, while this changed text correctly describes it as an analytical reference. Rename the heading so the tutorial does not imply that this single analytical fit establishes scientific ground truth.

Addressed the outside-diff terminology finding in a618c76: Part 6 now says “Analytical reference posterior” instead of “Ground-truth posterior.” This is a one-line Markdown-only change; every code-cell source, output, ID/type, execution count, and metadata field remains unchanged from the validated run 33147092231 artifact. |
