- Server no longer mirrors app.Runtime services (gov/svc/pwSvc/...): 574 call sites now use accessors in runtime_accessors.go - backgroundLoop (mutex+sync.Once) stops sweeper/publisher/reminder/wsGC goroutines race-free (baseline44161d2areproduced DATA RACE; now green under -race) - goose 00071 duplicate (dialogue merge1da17a28brought two 00071): context-conflict-adjudications renumbered to 00072; dev DB applied only through 00070 so zero data migration - task_finalize tests build minimal app.Runtime; test injection via serverTestOverrides + setOverride* (explicit-nil markers for fail-closed cases)
