- CallerContextService: fetches lead profile, appointments, call history,
activities in parallel. Caches in Redis (5 min TTL). Renders as
human-readable KB section — no UUIDs exposed to the LLM.
- Caller resolution controller: prewarms context cache on resolve
(fire-and-forget) so the AI stream has a cache hit.
- AI chat stream: injects caller context into system prompt KB instead
of raw Lead ID. LLM answers patient questions from context, no tool
calls needed for current caller data.
- Eliminates UUID hallucination: LLM never sees leadId or patientId,
can't pass wrong ID to wrong tool parameter.

- POST /api/caller/invalidate — clears Redis cache for a phone number
- WorklistController: resolves agent name from login cache (avoids currentUser query)
- AuthController: caches agent name in Redis during login (keyed by token suffix)
- WorklistModule: imports AuthModule (forwardRef for circular dep)
