PR 58061 from Hartley McGuire fixes frozen errors that surface when local cache and the error reporter get lazily initialized after the app is…

Second theme: a string of precise, narrow correctness fixes from contributor 55728. PR 58058 stops a wasted database query when a grouped calculation is run against a relation that can never match any rows — same logic Rails already applied to simple counts and sums, now extended to grouped ones. PR 58057 closes a…

Worth a quick mention: PR 58054 removes duplicated fallback-value logic between text field and color field, and PR 58062 fixes a subtle eager-loading gap in Action View's template sources.
