Developer documentation

The public developer documentation describes the supported library:

Private specifications, implementation plans, investigation logs, review transcripts, release checklists, and design prototypes belong in the ignored .private-dev/ directory at the repository root. Its README.md indexes current work and dated archives. It is intentionally absent from the published documentation and source distribution. Do not force-add private notes.

The 2026-09-05 archive preserves original relative paths and contents, including the historical phase roadmaps, merge evidence, namespace and dashboard proposals, and finetuning plans. These records explain past decisions; released source, public contracts, and passing release gates define current behavior.

Some historical files remain public because active tools consume them as contracts: proposals/namespace/_rename_map.tsv supports generation and ABI doc-lint; the three docs/architecture/aom_robust_hpo_*.csv manifests and roadmap/phase-7f-aom-robust-hpo-portfolio.md are inputs to the AOM integration contract tests. Their contents remain unchanged from the published baseline. They are executable acceptance evidence, not disposable planning notes; archival copies are retained privately as well.
