"""bluesky-pds — recipe-specific functional test (Phase 2 P3).

GETs the atproto session endpoint `/xrpc/com.atproto.server.getSession` WITHOUT an auth header.
Asserts the PDS responds with 401 Unauthorized — proves the auth subsystem is wired correctly:
- 200 = anonymous access leaked (would be a security bug).
- 401 = correctly enforced.
- 404 = route missing (PDS misconfigured).
- 5xx = backend broken.

Distinguishes "the atproto XRPC server is alive AND its auth contract is enforced" from generic
HTTP 200 health. Non-vacuous: each non-401 status indicates a different class of defect.
