Let captured Leader Skill owners revive other leaders

User ruling 13 October 2026: the original faction keeps its existing Skill
assignment while its trained leader is captured. Reviving a different eligible
own leader is legal and simply draws no replacement card while that assignment
exists (selected reading of authorized supplied Advanced physical p21 "if you
have no Leader Skill Card"). Not a new publisher ruling; captor lower-band use,
card movement and death-return unchanged.

Remove the replacement-question veto that suppressed the entire ordinary/Ghola
revival: leaderSkillRevivalBlocked/requireLeaderSkillRevival, the gholaLeaders
early return, the view revival.leaders: [] filter and the beginRevival/Ghola/
Emperor-special-Karama call sites are gone. offerRevivedLeaderSkill is
unchanged and still suppresses a second assignment or draw.

Rewrote the two committed rejection assertions
(tests/advanced-native-skills.test.ts, tests/leader-skills-capture.test.ts) and
added native regressions covering ordinary paid, held-Ghola and Emperor special
Karama revival from a genuinely captured skilled state: exact cost, no draw or
offer, retained captive/card/controller and a conserved all14 deck.

-## Remaining separate ruling
+## User ruling — 13 October 2026
+
+The original faction retains its existing Skill assignment while its trained
+leader is captured. Reviving a different eligible own leader is legal, but
+does not offer or draw a replacement Skill while that original assignment exists.
+This is the user's selected interpretation of the authorized supplied Advanced
+physical p21 condition "if you have no Leader Skill Card"; it is not a new
+publisher ruling. The physical card still accompanies its captive, and the
+normal band remains unavailable to both factions until the captive returns.
+The existing lower battle-band and death-return mechanics remain unchanged.
+
+The engine's earlier replacement-question guard wrongly suppressed the whole
+ordinary/Ghola revival, not merely a replacement offer. The ruled implementation
+removes that revival veto while retaining the existing one-assignment-per-owner
+offer check. No second assignment, forced draw or replacement card is introduced.
 
-Capture does not settle whether the original faction counts as having no skill
-card while its only card is attached to a captive, and therefore whether a
-later own-leader revival may create a replacement assignment. That entitlement
-should remain gated until separately ruled. It does not affect the custody and
-visibility conclusion above.
