~x-ai/grok-latest → A (2:1)

A replaces hand-maintained ns allowlists with a single ^test\..+ auto-discovery rule, a lasting design fix so new suites (e.g. test.ranking) run without edits to tests.edn or CI. B only deletes a redundant zero-ratio early-return already enforced at the DSL/handler boundary and retunes one unit test—correct hygiene, but smaller lasting impact than the discovery simplification.
