yoi/.yoi/tickets/closed/20260607-031439-ticket-role-launch-config-strict-validation/resolution.md

Implemented, reviewed, merged, and validated.

Summary:

• Added strict Ticket role launch readiness validation while preserving backend config loading/list/show behavior.
• Role launch planning now rejects missing role table, missing role profile, explicit top-level profile = "inherit", and unresolvable concrete selectors before spawn.
• plan_ticket_role_launch(_with_config) uses launch-specific validation instead of implicit role defaults.
• No implicit builtin/default/inherit fallback was added.
• TicketRoleLaunchPlan::spawn_config still defensively rejects inherit.
• Diagnostics are bounded/actionable for Panel/launcher surfaces.
• Init/scaffold generation was intentionally not implemented here; ticket-init-role-profile-scaffold remains the next task.
