Memory Mechanism

1. Why memory is needed

Industrial conversations are rarely one-shot.

Users often continue asking inside the same context:

• the same line
• the same anomaly
• the same time period
• the same review thread

Without memory, the system forces users to restate context repeatedly.

2. Typical memory layers

Memory type	Purpose
Conversation memory	keep the immediate thread coherent across turns
Task memory	keep focus on the current investigation topic
Preference memory	remember presentation or role preference where appropriate
Operational memory	connect repeated cases or follow-up sessions when allowed

3. What memory improves

• fewer repeated clarifications
• better follow-up continuity
• smoother diagnosis flow
• stronger connection between current question and previous context

4. Boundary

Memory should improve continuity, not weaken governance.

It still has to respect authorization, data boundary, and review requirements.
