Settings that fail validation are labelled

Rejected settings are tagged as invalid-setting so warnings can name where the bad value came from.

What

A setting rejected by validation is now attributed to an invalid-setting source instead of landing in the default bucket, so warnings can say where the bad value came from. Parent managed settings are also run through a validator that records their source.

Evidence

invalid-setting

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
