PR #5 rebuilt upstream requests with the default redirect mode (`follow`), causing the Worker to follow OAuth callback redirects itself. The browser received the final response instead of the redirect and its authentication cookies, breaking SSO through Linkup. Set the upstream redirect mode to `Manual` while preserving streamed bodies. Add a Worker integration test that verifies the 303 status, Location header, and both Set-Cookie headers reach the client. Update Wrangler entry points and CI placeholder artifacts to the worker-build 0.8 output paths so CI runs the current Worker. Validation: - The new regression test failed before the fix (200 instead of 303) and passed afterward. - All 11 server integration tests passed with the local Worker running (`cargo test -p linkup-server-tests -- --include-ignored`). - `worker-build --release`, `cargo fmt --all --check`, and `git diff --check` passed. The Worker needs redeploying for the fix to take effect; live Google SSO has not been retested.
