- * Promotes the {@code auth_token} cookie to an {@code Authorization} header
- * so that browser-side requests to {@code /api/*} authenticate the same way
- * SSR fetches do.
- *
- * <p>The SvelteKit login action stores the full HTTP Basic header value
- * ({@code "Basic <base64>"}) in an HttpOnly cookie. SSR fetches from
- * {@code hooks.server.ts} read the cookie and pass it explicitly as the
- * {@code Authorization} header. In the dev environment, Vite's proxy does
- * the same on every {@code /api/*} request (see {@code vite.config.ts}).
- * In production, Caddy proxies {@code /api/*} straight to the backend and
- * does NOT translate the cookie — so client-side {@code fetch} and
- * {@code EventSource} calls reach the backend without auth, get
- * {@code 401 WWW-Authenticate: Basic}, and the browser pops a native dialog.
- *
- * <p>This filter closes that gap: if a request has an {@code auth_token}
- * cookie but no explicit {@code Authorization} header, promote the cookie
- * value (URL-decoded) into the header before Spring Security inspects it.
- * Explicit {@code Authorization} headers are preserved unchanged.
- *
- * <p>See #520. Filter runs at {@code Ordered.HIGHEST_PRECEDENCE} so it
- * mutates the request before any Spring Security filter sees it.
- *
- * <p><b>Scope:</b> only {@code /api/*} requests are touched. The
- * {@code /actuator/*} block in Caddy plus the open auth/reset paths in
- * {@link SecurityConfig} must NOT receive a promoted Authorization.
- *
- * <p><b>⚠ Log-leakage warning:</b> the wrapped request exposes the
- * Authorization header via {@code getHeaderNames}/{@code getHeaders}. Any
- * filter or interceptor that iterates request headers will see the live
- * Basic credential. Do NOT add a request-header logger downstream of this
- * filter without explicitly scrubbing the {@code Authorization} field.
