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.

+## 13 October 2026 — captured Leader Skill replacement ruling
+
+The user resolved the previously gated captured-card replacement question: the
+original faction keeps its existing Skill assignment while its trained leader
+is captured, so reviving a different eligible own leader is legal and simply
+draws no replacement card while that assignment exists. This is the selected
+reading of the authorized supplied Advanced physical p21 condition "if you have
+no Leader Skill Card"; it is not a new publisher ruling. The captor's
+lower-band-only use, the captive's card movement and death-return are unchanged.
+
+The engine's earlier guard vetoed the whole ordinary/Ghola revival instead of
+only the replacement offer. `leaderSkillRevivalBlocked`/`requireLeaderSkillRevival`,
+the `gholaLeaders` early return, the view `revival.leaders: []` filter and the
+beginRevival/Ghola/Emperor-special-Karama call sites are removed.
+`offerRevivedLeaderSkill` is unchanged: one assignment per owner still suppresses
+a second offer or draw.
+
+Program-level BEFORE: on the pre-cutover revision the rejected-action assertions
+at `tests/advanced-native-skills.test.ts:258` and
+`tests/leader-skills-capture.test.ts:322` required ordinary revival to throw
+`/replacement-skill ruling/`, and both passed then. The ordinary case was also
+re-confirmed from a throwaway pre-cutover `git worktree` at HEAD: the projected
+ordinary and Ghola targets were empty and both `reviveLeader` and the held Ghola
+card rejected with the replacement-skill ruling, state unchanged.
+
+AFTER (bounded changed-path smoke, no fabricated state):
+
+- `tests/leader-skills-capture.test.ts` (6/6): a captured skilled leader keeps
+  its public assignment while another own dead leader revives for its exact
+  printed cost, with no draw/offer and a conserved all14 deck; the Collection
+  Medium bot plays the held Ghola to revive a dead disc, no replacement offer.
+- `tests/advanced-native-skills.test.ts`: a captured native trainer keeps its
+  physical skill while another own leader revives with no replacement offer.
+- `tests/captured-skill-revival.test.ts` (`fixture-captured-skill-revival.ts`):
+  native classic Atreides/Harkonnen setup; four real battles genuinely kill
+  `atreides-2/3/4` and `atreides-0`; the fourth is a real Capture + Keep of the
+  trained `atreides-1`; next-turn Revival offers `atreides-0`. Ordinary paid
+  revival (spice 10→5) and the held Ghola free revival both succeed, no draw or
+  offer, intact assignment `{owner a, leader atreides-1, skill sandmaster,
+  controller h, captured true}`. Living captive, wrong actor, cross-phase,
+  second-leader and consumed-Ghola attempts reject without mutation; one exact
+  Easy bot ordinary target is proposed.
+- `tests/captured-skill-special-revival.test.ts`
+  (`fixture-captured-skill-special-revival.ts`): native classic Emperor/
+  Harkonnen/Guild setup; paid Carthag deployment and a sealed projectile battle
+  genuinely kill untrained `emperor-1` while a real Capture + Keep retains
+  trained `emperor-0`; next-turn Revival's free Emperor special Karama revives
+  `emperor-1` (wallet 8→8, `specialKaramaUsed` true, Karama discarded once, no
+  replacement offer, unchanged captive/assignment/deck) and reaches the native
+  phase5 suffix. Wrong captive/foreign target, wrong phase/actor, mixed
+  forces-plus-leader, replay and once-use reject immutably with one exact Easy
+  bot Special action.
+- Related 16-file union 145/145; the two new files 4/4; `tsc --noEmit` and
+  `oxlint` clean.
+
+Docs updated: `RULE_DECISIONS.md` (new user decision),
+`LEADER_SKILLS_CAPTURE.md`, `LEADER_SKILLS_RULES.md` (boundary resolved),
+`NEXUS_CARD_RULES.md` and `CURRENT_STATUS.md`. The Ambassador free-revival
+route was unavailable in the genuine classic three-seat position and remains
+unexercised. No expanded-slice, complete-mode, save/deployed or assurance claim
+follows.
