The non-blocking Full Suite tier on main was red on shards 2 and 4:
- roadmap-store schema assertion lagged core's SCHEMA_VERSION bump to 117
(landed in FN-6277), so it still expected 116.
- useCeSessions "cancel surfaces a transport error" failed deterministically:
a session with an in-flight status keeps the poll fallback running, and a
successful background list refresh called setError(undefined), wiping the
cancel error before it could be observed. Background refreshes (poll + push)
now leave action errors intact; only user-initiated/initial refreshes clear.
