+### Added

+- Add `docs/internals/` developer reference: three notebooks covering all nine pipeline stages (Stage 1 data build, Stage 2 calibration matrix assembly, Stages 3–4 L0 optimization and H5 assembly) plus a README with pipeline orchestration reference, run ID format, Modal volume layout, and HuggingFace artifact paths.
+
+### Changed
+
+- Update public-facing methodology and data documentation to reflect the current pipeline implementation; pipeline now uploads validation diagnostics to HuggingFace after H5 builds complete.
