Changelog

Unreleased

Cluster orchestration and sweeps:
- added cluster.yml Slurm contract support to pic.flow run (--cluster, --scheduler, --no-submit).
- added scheduler artifact generation and submission metadata (solver.sbatch, post.sbatch, submission.json, manifest.json).
- added pic.flow sweep for parameter studies using Slurm job arrays with post-stage dependency chaining.
- added study aggregation outputs (metrics_table.csv, results/plots, summary.json).
- added templates: master_cluster.yml, master_study.yml.
- added docs pages: cluster run guide and sweep/study guide.
Initial Doxygen docs scaffold, architecture, and developer guide pages.
Main docs refresh:
- updated tutorials/references for current YAML -> pic.flow -> C contract.
- added method overview pages (CurvIB, fractional-step, dual-time RK4, pressure Poisson/multigrid, walking search, interpolation/projection, IEM/averaging).
- added non-dimensionalization page and linked it into nav/reference flow.
- updated landing page visuals (docs/assets/curv.gif, docs/assets/paraview_flat_channel.png).
- added maintenance backlog page for low-priority warning/refactor tracking.
Repository organization updates:
- moved build configs to config/build/ with Makefile legacy fallback support.
- moved shared grid.gen profile to config/grids/coarse_square_tube_curved.cfg.
- converted sandbox/ into explicit developer-sandbox documentation.
- standardized internal directory guides to guide.md (non-root).
- moved documentation media into docs/assets/.
- removed non-root README.md files (single top-level README.md retained).
- routed Doxygen warning output to logs/doxygen.warnings.
Hardened YAML -> C config contract across case/solver/monitor/post:
- scalar-only da_processors_* contract with validation.
- structured mappings for analytical type and monitor subdirectories.
- post input extension keys and statistics pipeline wiring.
Added config contract documentation set:
Added ingress drift guard:
- scripts/audit_ingress.py
- scripts/audit_ingress_manifest.json
Added documentation note on data-driven particle-closure expansion:
- offline workflows supported now via solver/post artifacts.
- tightly coupled inference requires runtime-selectable closure interface extension.
Removed obsolete stubs/ archive from repository after extracting useful documentation content.
