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.

+## 24 October 2026 — Cohort-eligible Ambassador leader and KH repeats
+
+Use one phase/slot/price-independent death-cohort quote for normal Revival and
+the independent Tleilaxu Ambassador. First returns stay immediate; repeats retain
+their ordinary condition, including Ecaz identity bookkeeping and Advanced
+Auditor permission. Preserve an opening before clearing death so the free return
+does not close remaining ordinary choices. KH keeps its own token/loss history
+and advances above both the actual owner cycle and its old marker. Ordinary
+phase/payment/prevention/one-leader controls and native early service stay in
+normal Revival. Persistent controls explain the provisional repeat composition.
+
+A disjoint helper lane, bounded review and owner integration pass13-file114/114,
+types/lint/build, two controlled Basic return-to-next-Revival programmes and one
+controlled Advanced KH actual-entry programme. Original public Basic sources
+use72/73 actions before assigned native repeat/cohort histories; real free return,
+entrant completion and paid4 ordinary revival use27 actions each. Advanced actual
+entry3 followed by return/end2 yields cohort3/old2 → marker4. Twelve existing legal
+profiles finish original entry; controlled income allow/cancel preserves deaths2.
+Focused feedback exposed the lost all-first-dead opening and corrected a missing
+Advanced transport-allowance fixture step. [Source, policy, exact proof and limits](TLEILAXU_AMBASSADOR_RULES.md#ordinary-repeated-leaders--24-october-2026).
+This is provisional composition and controlled runtime evidence, not earned
+repeat-battle histories or complete mode acceptance. Wider custody/modules,
+comprehensive assurance and deployed acceptance remain open. No strategic tuning
+or saved-room/reset/restart/deployment operation.
