"""Requirement 2.4 of the removal spec: the removed agentic plane is named only in its retirement notes.
A case-insensitive search of ``src/``, ``tests/``, ``pyproject.toml`` and the README may match only lines tagged
``retired 2026-..``: the retired-key table and the one warning in ``config.py``, the retirement tests, and the README's
plane section. The spec's own slug (its directory name, the equality instrument's file name) is a citation of the
removal, not a use of the plane, and is not counted. The pattern is built at runtime so this file does not match it.
