Pages projects historically configured bindings in the dashboard alone. A Wrangler configuration file is now supported, but Pages treats the file as a Pages configuration only when it contains pages_build_output_dir. Without that key the file is assumed to belong to a Worker and the Pages build ignores it entirely, which looks like the bindings being dropped.

Once the key is present, the dashboard binding editor is disabled for that project and the file becomes the source of truth, including for preview, which is configured as a preview environment block rather than as a separate project. Migrating means transcribing every existing dashboard binding into the file before the next deploy, because anything omitted is removed rather than preserved.
