#45 — Harden the scenario-generation journey: persistent state, guided setup, and resilient progress

What to build

The Assistant's empty state offers direct actions to start a threat-group, custom, or AI-insider scenario instead of only reporting that none exists. When a result exists, the Assistant shows the scenario identity and originating page, and a Back to this scenario action returns the user to the originating page's re-rendered result and downloads.

Acceptance criteria

• With no scenario, the Assistant shows direct links to all three generation entry points
• With a scenario, the Assistant shows the scenario identity and originating page
• A Back to this scenario action returns to the originating page with its result and downloads re-rendered
• Tests assert the empty-state links, that the captured scenario + user message reach the Assistant model seam, and that the streamed response is retained (no assertions on model wording)

• Durable per-page results and Assistant round-trip #51 — Durable per-page results and Assistant round-trip
