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.

 # Dune implementation status
 
+## 13 September 2026 — Leader Skills setup, five disciplines and skilled capture
+
+The [first connected prototype](LEADER_SKILLS_RUNTIME.md) adds all fourteen
+physical cards and readable faces, source-ordered private setup, public battle
+posture, five card-role strength modifiers, death return and own-leader revival
+through controls, all four AI profiles and saved actions. The other nine effects
+remain missing; combined modules and public starts remain gated.
+
+The user's requested [capture research](LEADER_SKILLS_CAPTURE.md) resolved
+publicity through the known card's required movement with the leader. Harkonnen
+gets only its lower battle effect; surviving return and death retain physical
+custody. This is a component-based source inference. Captured replacement
+entitlement stays separately unresolved and explicitly guarded.
+
+Independent review found and fixed a Voice/mandatory-leader deadlock and invalid
+simultaneous assignment/offer custody. Focused capture review found no remaining
+blocker. The focused union passed **66 tests**, including genuine setup, scoring,
+capture and SQLite restart/concurrent setup and revival selections. Three sample
+games finished; their exact scope and source fingerprints are recorded separately.
+Browser setup, card inspection, AI assignment and refresh were exercised in new
+room `REF6YHN7`; narrow sidebar cards were made readable. All 291 opening rooms
+were backed up before QA. Final preservation and broad check results are recorded
+in the checkpoint commit and private report.
+
+The first broad run passed types/lint and 4,410 of 4,411 offline tests. Its one
+failure was an existing Discovery privacy test treating `treachery-32` as a
+substring match for hidden `treachery-3`. The exact physical pair now forms a
+deterministic scenario and assertions compare complete JSON string identities;
+the opponent's own card remains visible. Independent review and all six
+Discovery runtime tests pass. The broad run was repeated after this correction.
+During the follow-up, another user-reported outage stopped the server. All 292
+games survived; a fresh backup and necessary server start restored the same
+private prototype seat and pending Storm choice.
+
+The first broad run also exposed a pre-existing random Discovery test failure:
+the hidden identifier `treachery-3` matched the viewer's distinct `treachery-32`
+through a substring assertion. The regression now stages both physical cards
+and checks their complete identifiers; no production privacy behavior changed.
