Do not use this directory as a source of truth.

Everything below docs-dev/ is retained historical planning and implementation material. It may describe abandoned approaches, old dependency versions, temporary constraints, or behavior that has since changed.

• Do not consult, index, publish, or summarize this tree when documenting or implementing current component behavior.
• Do not infer current APIs or architecture from files in this tree.
• Use package source code as the implementation source of truth.
• Use the repository-level docs/ tree for current public documentation.

The implementation phase recorded here is complete. This directory remains only as historical context when a maintainer explicitly requests a particular file.
