-# PHPStan baseline for the `parameter.phpDocType` errors in WordPress core.

-# https://phpstan.org/error-identifiers/parameter.phpDocType
-#
-# Each entry is scoped to a single file and carries an exact occurrence count,
-# so that a new instance is reported as a new error rather than being absorbed
-# silently. Fixing an occurrence therefore means decrementing or removing its
-# entry here as part of the same change.
-#
-# The goal is to empty this file and delete it, along with the `includes` entry
-# for it in phpstan.neon.dist.
-#
-# Generated by `composer phpstan:baselines`. Do not edit by hand; regenerate with
-#
-#     composer phpstan:baselines -- --identifier=parameter.phpDocType
-#
-# which reruns the analysis with this file suppressed so the errors surface again.
