📋 Decision Context

Question:

Anonymous users see 'No sessions found' because VittoChatEngineService.effect() never calls setScope() for anonymous userId. Guest sessions are also silently abandoned when user logs in.

Task: Not specified

🎯 Decision Made

Chosen:

Fix engine to always call setScope + add migrateAnonymousSessions()

Options Considered:

1. Fix engine to always call setScope + add migrateAnonymousSessions()
2. Backend-sync sessions like ai-panel does
3. Ignore anonymous sessions entirely

💭 Reasoning

Root cause: the effect() guarded setScope() behind contextUserId !== 'anonymous', so anonymous users got no session created. Fix: (1) Always call setScope() with effectiveUserId = contextUserId || 'anonymous', so anonymous users get sessions immediately. (2) Add migrateAnonymousSessions(newUserId, newSpaceId) to VittoChatPersistenceService — re-scopes non-empty anonymous sessions to the real user. (3) Call migration before setContext() in the engine effect when AuthService resolves a real user. This is the minimal fix — backend-sync would be ideal long-term but is over-engineering for now.
