Emily Boudreaux e7e53ce682 Consolidate numerical research and preserve a reproducible handoff 
Document the baseline, hypotheses, measured results, failed approaches,
current policy defaults, and remaining rotating n=3 and virial limitations.
Include the authoritative LaTeX report, Pandoc-generated Markdown, compiled
PDF, source provenance, branch decisions, and consolidation validation.

Organize raw results and miscellaneous artifacts under working/ without
deleting them; version the directory guide, relocation hashes, archive
verifier, and report build/conversion checks. Keep build caches at their
original paths and clearly distinguish retained binaries from the validated
research build. Preserve experimental policies without promoting failed
trials to defaults.

Raw Blame History

Early-history fragment evidence index

Authored fragment: early.tex. Scope: original 16 September audit through the bounded reduced-surface study on 18 September. The 19 September native-harmonic, negative-density, density-order, and coupled-convergence material belongs to the companion later fragment.

The fragment cites the report files below; those reports identify exact producer commits, immutable commands, manifests, states, binaries, raw vectors/CSVs, timing exclusions, and audit results. No new FEM solve or numerical result was generated for this section. Archived initial audits are referenced at their proposed final repository paths. Raw campaigns are referenced at the consolidation archive path.

Numerical interpretation controls

  • Original audit HEAD alone was not the source under test; incoming optimized changes were preserved at baseline 80cc3d8.
  • All time-to-convergence comparisons require both frozen endpoints to pass the same independently measured full-J true gate. Failed controls have no finite measured time-to-convergence.
  • Nonlinear matched pairs follow evolving trajectories; fixed-update endpoint improvements are not speedups to the same solution.
  • Sampled and certified positivity are distinguished; enthalpy certification never certifies independent density.
  • All early J and Omega values are reference-unit inputs/results, never fractions of critical rotation.
  • Q4-only displacement enrichment is a retained negative experiment, not a recommended main-branch order change.
  • The L2/L4/L8 frozen reduced-surface study changes test/approximation space; reduced gates do not imply original full gates.
  • Original coarse shape residuals/excluded-force results remain visible even when the reduced norm and virial improve.
  • Original 40/160-restart controls, n=3 central border, initial beta/alpha grids, timer exclusions and unavailable timeout endpoint are described explicitly.

Source limitations

This history is synthesized from the saved primary project reports and their recorded artifact measurements. It does not independently rerun every FEM measurement. Later corrections and clarifications within those reports take precedence over earlier provisional summaries. The consolidated report should retain the reports and raw campaign directories so future investigators can reproduce individual measurements.

Consolidation precision checks

The normalization summary was checked directly against the separate value/residual registrations in physical_riesz.cppm (lines 408–463). The seed description was checked directly against its two ProjectCoefficient calls in stellar_equilibrium_projection.cpp; it now distinguishes coefficient initialization from solving the weak closure weighted L2 projection. Mathematical Jacobians are denoted A, while J continues to denote angular momentum.
