rewriter-syntaxProxied JavaScript is reaching the engine malformed — typically modern syntax (optional chaining, nullish coalescing, top-level await) surviving into a rewriter path that parses with an older grammar.
SyntaxError: Unexpected token '?'
rewriter-urlThe rewriter called the URL constructor on something that is not an absolute URL — commonly a data:, blob: or inline `javascript,` module specifier. Guard these and pass them through untouched.
TypeError: Failed to construct 'URL': Invalid URL
sandbox-storage-accessFramed third-party code asked for storage access and was refused. reCAPTCHA, SSO and any login flow will fail until the sandbox grants allow-storage-access-by-user-activation — and may still fail because the framed origin is validated server-side.
requestStorageAccess: Refused to execute request. The document is sandboxed, and the 'allow-storage-access-by-user-activation' keyword is not set.
console-error-deltaNot matched by a specific rule. Review for new failure classes worth encoding as rules.
