- boardwalk.BuildID hashes the dist tree plus the binary's build info once
per handler; X-Summer-Build on every response, {prefix}/build.json and the
summer-admin-build meta carry it
- the SPA reads the booted build, re-checks on focus, visibility and every
5 minutes, and shows UpdateBanner on a different build
- backend.uri prefix (default /backend) mounts the admin API at {prefix}/api/v1
and the embedded SPA shell at {prefix} with an api/ JSON 404 fallback
- cookie transport: an X-Requested-With login sets the HttpOnly summer_admin
cookie and returns no token; the backend guard reads the cookie after Bearer
- CSRF wrapper refuses cookie-only POST/PUT/DELETE without X-Requested-With
- boardwalk package embeds boardwalk/dist, rewrites index.html once per prefix
and sets cache and security headers
- framework admin OpenAPI pipeline (swag, swagger2openapi, openapi-typescript)
with prefix-relative paths and typed envelopes for the tracer routes
- admin/ Vite SPA: login, plugin rail, section panel and read-only list
through the openapi-fetch client typed by the generated schema
