+## What this is
+
+A corporate, multi-user **sales-training simulator**. Admins upload/describe a product → app
+analyzes it + generates 15 realistic customer personas (5 per intent tier A/B/C) with varied,
+partially product-aligned pains, negotiation levers, initiation modes (customer/seller),
+channels (Facebook/LINE), and latent-vs-revealable data. Trainees chat 1:1 (one-shot) to close
+a sale; customers resist/negotiate/refuse; a separate judge-LLM scores + coaches the result.
+
+Informed by MiroFish (CrowdSight engine) + the hermes-brain-and-tools CrowdSight plugin.

+- One persona = one chat per user (one-shot). Enforced in SessionStore + chat start.
+- Latent persona fields never leak to trainees pre-result.
+- LLM credentials live in `.env` only; never logged.
