Allow Ecaz Ambassador Duke acquisition for an existing ally

 - **No-Field, Face Dancer, worm and moving mobile stronghold:** the p.14 explicit No-Field/Face Dancer FAQ is about Terror. It is not an Ambassador FAQ. Ordinary committed force movement is supported by the broad entry trigger; a zero-force No-Field placement and a moving stronghold carrying forces need cause-specific classification. Record the actual arrival type rather than globally equating all `place()` calls with entry.
 - **Tleilaxu Ambassador revival accounting:** the effect supplies its own free amount/leader alternative, but does not expressly say whether prior normal revivals reduce it, whether it consumes subsequent ordinary quota/free allowance, whether dead-twice cycle prerequisites are waived, or whether the leader must satisfy normal revival eligibility. A Ghola card handler hardcodes a different force quantity and income classification and cannot settle those questions. Recruits doubles the current normal free rate; do not automatically double the Ambassador's printed four. Duke's Ecaz-only restriction is explicit; an ally benefit is not an exception.
 - **Independent free revival versus blocked faction advantages:** E1's Tleilaxu payment sentence and technology token rules need their own event classification. `collectRevivalIncome(..., free=true)` currently awards at most once per faction/turn; `ghola=true` awards per use. An Ambassador is not a Ghola card, so choosing that boolean solely to obtain a payout invents a rule. `techIncome` is phase-scoped and once-per-turn; an Ambassador revival during Shipment and Movement must not manufacture Axlotl income outside its printed phase. La La La/free-revival prevention and the Tleilaxu special prevention must be checked by their own wording, not inherited from normal quote plumbing. No specific E3 combination answer was found.

-- **Ecaz effect assigned to an existing ally:** the general benefit-sharing sentence and the specific new-alliance Duke loan can be read differently for direct acquisition by an already allied faction. The existing same-turn-loan state must not be reused silently for every shared effect. New-alliance rejection/no-eligible-Duke, and an impossible effect invoked only to recycle a token, also require an explicit no-op consumption policy.
+- **Ecaz effect assigned to an existing ally:** the [26 October selected direct-acquisition composition](ECAZ_DUKE_ACQUISITION.md#existing-ally-direct-acquisition--26-october-2026) now connects printed sharing. Ordinary source `ecaz` lasts until battle use; the distinct new-alliance `ally` loan remains turn-long. This is an explicit provisional tenure choice under the recommended-policy authority. Same-recipient no-op remains rejected before token consumption; wider no-op/alliance edge policies stay separate.
 - **Post-trigger cancellation:** the p.16 entry is placement-specific. Do not add a compulsory generic `ecazAmbassadorEffect` Karama response for all eleven effects. A separately invoked native advantage, such as Harkonnen's additional card or BG's advisor, can still have its own existing cancellation window. Such child windows must return to the Ambassador continuation.
