Equivalence Reasoning

stylistic

The agent patch implements the core behavior: adds a distinct `base64url` string check kind, validates with a URL-safe regex, emits `invalid_string` with `validation: "base64url"`, exposes `.base64url()` and `.isBase64url`, and updates both `src` and `deno/lib` surfaces. It also adds tests confirming base64 vs base64url distinction. Differences from gold are non-functional (docs/tests/formatting choices).

Code Review

correctness: 4/4introduced bug risk: 4/4edge case handling: 3/4maintainability idioms: 4/4

The agent patch likely satisfies the intended base64url feature: it introduces distinct validation semantics, API surface (`base64url()` and `isBase64url`), metadata/error tagging, and matching tests with no material correctness gaps apparent.
