+## Interpretation citation policy v2
+
+New resolution input artifacts additionally freeze
+`interpretation_protocol_version = 2`. Their context uses `linked_capture_v2`
+citation markers and `case_interpretation_resolved_v2`. Existing artifacts keep
+the original marker-free context, prompt, validation and feedback behavior.
+
+The selected `entity_id` must still be present in `relevant_entities`. Its
+`source_ids` must include an original mention and either the entity alias or an
+inline `entity_name_lookup` fact backed by the **same capture** as that selected
+entity. A matching DB fact is sufficient identity evidence; a redundant N alias
+is not required. An unrelated fact cannot satisfy this requirement. Missing
+entities and missing provenance receive distinct error codes.
+
+Correction feedback for the new prompt lists missing entities, the exact field,
+and permitted original-mention/capture aliases. It reports these even alongside
+source-kind errors, rather than waiting for multiple correction rounds to expose
+each issue. Tester observations and technical facts remain strictly separated.
+The prompt also distinguishes a scoped broad/localized lookup ambiguity from
+an independently selected, specifically named subject; the former does not by
+itself invalidate the latter.
+
+The second real Gemini reply from the schema trial is an offline regression
+fixture. It is accepted with its original response and citations under the new
+policy; the old rule continues to reproduce the recorded historical rejection.
+This does not overwrite or accept artifacts in the exhausted REVIEW case.
