Support cohort-eligible Ambassador leader and KH repeats

Replace lifetime first-death caps with the selected provisional composition: first returns remain immediate, while later native leaders and KH must satisfy their existing ordinary death/cohort conditions. Extract one phase/slot/price-independent cohort quote for ordinary Revival and the independent Ambassador. Preserve ordinary timing, payment, prevention, native early service and one-leader controls.

Snapshot an opened cohort before a free return makes a leader alive, preserving remaining ordinary returns. Keep Ecaz identity tracking and the shared Duke permission separate. KH retains activation/loss history and five native discs; update its marker above the actual opened owner cycle and old marker. Independent grants retain ordinary allowance and income policies. Explain eligibility in persistent controls and source-labelled reference.

Verify related rules/controls, types/lint/build, controlled native/copied free-return-to-next-ordinary-Revival programmes layered on original public Basic paid-entry sources, controlled Advanced KH actual entry/return, income allow/cancel and twelve minimal legal policy continuations. Assigned repeat/cohort facts are explicitly controlled, not claimed original battle histories. Full modes, wider custody/module combinations, comprehensive assurance and deployed acceptance remain unfinished. No strategic calibration, saved-room operation, reset, restart or deployment.
