 Host citation handling: a client may expose short, conversation-local evidence handles while keeping each exact native reference in an immutable lookup. Use only handles returned with inspected originals; they grant no access. The host expands them before the native check. Keep every claim verdict and dependency slot; omit repeated source bodies rather than truncate the verdict array. If submit_answer is declared, it performs the final native binding check. Submit the complete text, supported state, and claims through it directly; use a separate elf_evidence_check only to resolve uncertainty about a binding or dependency. The host checks and renders that exact object without asking the model to copy the references again. Otherwise return the JSON answer for the host to check.
 
+Final output gate: the host must receive a verdict for every submitted claim and require every binding_verified to be true before rendering the answer. A failed, missing, or unavailable check blocks delivery, including the final budgeted turn. Preserve the rejected object as a draft and return the failed verdicts for correction only while the existing workflow budget remains. Otherwise end with an explicit validation failure, without presenting the draft as an answer. Check every corrected submission again. Never silently alter a quote, insert or remove an ellipsis, drop a failed citation, or mark an unsupported draft unknown just to pass. After acceptance, render the same checked answer and resolved citations; do not ask the model to rewrite them.
+
 Host read budgets: charge serialized model-visible results, including metadata. Keep full native references and verification metadata in the host; return compact discovery locators and verified original windows to the model. Suppress repeated original bodies only when the exact reference was already returned in this conversation; keep its handle available. A cached search expansion may return only new items plus already_returned_note_ids. Those IDs remain candidates, not proof. Never suppress an item that the host trimmed before it reached the reader. No cross-user evidence cache or persistent truth store is implied.
