"""Field references and leaf constructors shared by the unit-level tests.

These are pure whoosh-compat AST values with no state and no database
behind them, so they stay plain module-level functions rather than
fixtures. ``NOTES`` is the reason this module exists at all: notes is a
JSON field, so addressing its text means naming a subpath, and spelling
``wc.FieldRef("notes", "note")`` out once per test file invites two of
them to disagree.
