 Coordinator question recommendation: ask explicitly about independent versus ordinary force/leader allowance, waived leader prerequisites, and whether the leader portion is optional. The related [Ambassador accounting questions](TLEILAXU_AMBASSADOR_RULES.md) are already pending; do not duplicate those or assume an answer covers differently worded Nexus text. No user question was sent by this audit.
 
 Future revival quote inputs should retain source `nexusTleilaxuSecretAlly`, chosen leader/Kwisatz identity, exact normal/starred force counts, payment and existing usage histories. Require a resolved accounting policy before mutating ordinary counters. A receipt must preserve original revival, subsequent Homeworld deployment and phase continuation once; no card/force/spice effect should be inferred afresh from a restored hand or current Tanks.

+The requested web search found no publisher/designer answer to the three questions above. The [publisher-authored expansion rulebook, pp. 11, 14–16](https://gamers-hq.de/media/pdf/0f/7a/86/Dune_EcazMoritani_Rulebook_EN.pdf) explains Nexus cards and answers other faction interactions, but does not specify whether this grant is additional to ordinary revival, consumes the ordinary leader slot, or permits using only one part. The printed card wording quoted above establishes quantities and prices, not these accounting or partial-use rules. Search-result summaries that conflate Secret Ally with native Tleilaxu revival or Ghola are not rulings. All three questions remain pending; do not implement an inferred answer.
