Addresses all critical findings from review:
- KOL identity via prompt_share_profiles, not platform_role
- Prompts stored as sealed article_templates, not parallel system
- Platform-level packages with proper API path separation
- Generation pipeline integrated with existing tx/quota/idempotency
- Variable model with immutable IDs and version snapshots
- Independent kol_assist_tasks table (decoupled from template_assist_tasks)
- Complete resource lifecycle and auth chain
- Consistent tenant-level subscription entity
