SPECTRAX-GK v1.6.5

SPECTRAX-GK v1.6.5

Release focused on tightening the quasilinear validation guardrails and shipping the current manuscript/release evidence cleanly.

Changes

• Updated quasilinear diagnostic artifacts for the current 11-case validation ledger.
• Locked the current fail-closed absolute-flux result in tests and documentation: the best regularized spectral-envelope candidate remains above the transport-error gate, so no runtime/TOML absolute-flux predictor is promoted.
• Regenerated and compressed the quasilinear residual-anatomy and regularization preview figures.
• Fixed wide package coverage shards that still expected the obsolete ten-case quasilinear snapshot.
• Kept release-scope documentation explicit about deferred W7-X zonal/TEM lanes and scoped nonlinear optimization claims.

Validation

• GitHub CI passed on main for commit 5e845f1.
• Wide package coverage matrix passed.
• Release readiness, repository-size, artifact-manifest, docs build, package build, and twine check passed before tagging.
• PyPI publish succeeded for spectraxgk==1.6.5.

Scope

• Production-closed claims remain limited to the validated release surface: independent-work parallelization, scoped nonlinear optimization evidence, and guarded quasilinear model-development diagnostics.
• Universal absolute quasilinear flux prediction, broad nonlinear domain-decomposition speedup, W7-X zonal long-window closure, and W7-X TEM/multi-flux extension remain outside this release scope.
