v1.4.0 — RFN epic (batch-refine / cluster-HITL)
Cluster grilling up front, run execution unattended, review once (RFN-001..009). Everything is opt-in and default-off; attended /capiva:sprint is unchanged. The batch-refine workflow (/capiva:refine + REFINING + context-answerer) ships EXPERIMENTAL — validated by the RFN-002 eval gate + a tabletop dry-run, not yet live-run. Full details in CHANGELOG [1.4.0].
