SPECTRAX-GK v1.6.4

SPECTRAX-GK v1.6.4

Release-scoped tightening for validation, release guardrails, and publication artifacts.

Highlights

• Refreshed the RBC(1,1) transport landscape panel with 16 strict long-window nonlinear overlay points: the negative-side scan plus the zero-offset baseline now use replicated post-transient ensembles.
• Added tracked runtime/memory provenance sidecars for the shipped performance panel.
• Hardened the release workflow so PyPI publication is gated by release-readiness, artifact, repository-size, performance, parallelization, and quasilinear-promotion checks.
• Tightened README/docs language around parallelization: production claims cover independent k_y scans, quasilinear batches, and UQ ensembles; nonlinear domain decomposition remains diagnostic until production numerical-identity gates are complete.
• Clarified quasilinear and nonlinear optimization scope: current figures support validated diagnostic/model-development claims, with absolute-flux promotion and broader long-window nonlinear optimization evidence continuing under the manuscript validation plan.

Validation Notes

• The RBC(1,1) positive-side long-window nonlinear overlays remain explicitly scoped as pending rather than silently inferred from reduced or startup-window estimators.
• Runtime and memory summaries now have versioned CSV/JSON sidecars under docs/_static/.
• Release readiness and scope tests cover the new guardrails.
