+                on the cue itself.
+            merge_strategy: How ``payload_override`` combines with the
+                cue's stored payload. ``"merge"`` (server default) shallow-
+                merges with override wins on key collisions. ``"replace"``
+                uses override as the final payload, ignoring ``cue.payload``.
+            send_at: Optional ISO 8601 timestamp (or ``datetime``) to
+                delay this fire. If omitted, the execution is scheduled
+                immediately. Per-fire scheduling landed in cueapi #618.
+            exit_criteria: Optional list of required-assertion keys for
+                §14 work-verification-light (cueapi #632). When non-null,
+                the receiver MUST report values for every key under

+            idempotency_key: Optional opaque caller-supplied dedup key
+                (cueapi #683, ≤256 chars). Same key on the same cue
+                within 24h returns the cached execution without firing
+                again (matched by SHA-256 fingerprint of the canonicalized
+                body). Same key + DIFFERENT body in the window returns
