+### Tanks Cunning composition — 8 October 2026
+
+The printed Ecaz Cunning supplies the Tanks allowance. Only its native,
+unallied Ecaz holder may spend the actual Ecaz Nexus card to perform this
+acquisition at the existing quiet Battle boundary. The pure custody transition
+permits a dead disc only for `ecazNexus`, with controller, acquisition turn and
+source all null before acquisition. It revives the existing disc and assigns
+Ecaz's current-turn Nexus custody. Moritani, ordinary Ecaz Ambassador and ally
+acquisitions still reject a dead Duke; capture/Ghola and Advanced Harkonnen
+gates are unchanged.
+
+Clearing the old battle-use stamp on this independent resurrection permits
+one new use under the normal shared-Duke lifecycle. That allowance/use
+composition is **provisional**, not an inspected GF9 FAQ ruling. A living,
+already-used Duke remains unavailable; taking a living disc does not clear
+its stamp. There is no separate paid revival charge or native revival slot
+for this Nexus action. This does not broaden the exact user ruling that only
+Ecaz revives Duke, including when using the Ghola Treachery Card, into support
+for Cunning's exceptional Ghola custody or return destinations.
+
+Focused cases are authored in [the quote/source tests](../tests/nexus-ecaz-duke-quote.test.ts):
+source-specific dead-disc rejection, same-disc revival with preserved death
+history and cleared prior use, real Basic/Advanced setup and physical Nexus
+spending by all four bot profiles, living-used rejection, set-aside custody,
+and the unchanged historical receipt shape. These additions are not a claim
+of executed checks or live-control proof.
+
+Parent native Basic/Advanced smokes now spend one original Nexus, acquire
+the same Tanked Duke with deaths2 retained and old use cleared, then seal
+him in a real new battle and release once after survival. No spice is
+charged for the Nexus action. The live owned control in Chromium reaches
+the same acquisition, death history and card disposal against the native
+engine. This is isolated rule/control proof, not HTTP, recovery or deployed
+acceptance; no broad suite was run.
