Access to and manipulation of core WordPress entities.

/**
 * Returns a copy of `query` filtered to only the keys that affect resolution
 * identity (`context` and `_fields`), or `undefined` when none are present.
 * This mirrors the normalisation that the data store applies when keying
 * resolved records, so that `finishResolutions` receives args that match the
 * keys used by callers who omit pagination params.
 *
 * @param {Object} query The raw query object.
 * @return {Object|undefined} Normalised query or undefined.
