Two conflated issues: (1) the raw-URL 303 redirect is already followed
correctly by establish.py's urllib-based probe -- re-running
publish-check now passes; the stale roster fail was from the 2026-06-16
sweep, not a live issue. (2) config-atlas was never actually registered
with the production hub (absent from the 60 sources at
reuse.coulomb.social/v1/federated despite hub_registered: true in the
roster) -- corrected to false. Local publish pass is now 61/61; hub
registration itself is blocked on REUSE_SURFACE_TOKEN, which has no
routing catalog entry -- needs Bernd to provide or route it.
