Prototype Leader Skills setup, battle disciplines and capture

Connect all fourteen physical skills and private setup to five card-role battle
modifiers, public posture, Harkonnen skilled capture, death return and optional
own-leader revival through controls, legal AI and persisted room actions.
Nine skill effects and combined-mode/publication acceptance remain unfinished.
Captured replacement entitlement and foreign ghola integration stay guarded.

Fresh publisher/designer research supports skilled-capture publicity through
its unique known physical card; this is recorded as a component inference.
Independent review found and fixed Voice/must-use-leader and invalid saved
assignment/offer cases. A pre-existing Discovery privacy assertion confused
card ID prefixes; the corrected deterministic physical-pair scenario was
independently reviewed. The first broad run was 4410/4411; corrected final
verification passes types/lint, all 4411 offline tests, build and 43 HTTP tests.
Final durations: check 149741ms, build 6659ms, integration 28274ms.
Source fingerprint: aef655ac1ebc0eb2f64294e13d3d27337167312cf8ab17568a166ee9c39f6a85.
Private final report: 20260913-leader-skills/checks-final/report.json.

Three seeded prototype games completed with no rejected bot candidates. Browser
setup/card inspection/refresh passed. Another user-reported power outage stopped
the server; backup and necessary restart restored the same private seat. All
292 games at restart and their original application records remain unchanged;
33 isolated HTTP-test rooms bring the current total to 325. No database reset.

Efficiency: one shared setup/lifecycle implementation supports five connected
role effects; selective existing agents handled catalog/UI/tests/research and
independent reviews. One repeated broad check was required by the reproduced
ID-prefix assertion failure. Aggregate goal counter rose from 65529766 to
67313673 through this checkpoint (1783907), including inherited context and
coordination; this is not a billing or savings estimate. Full goal remains active.
