Author: Platform Security, Legal & AI Engineering Squad

1. Context & Problem Statement

Interactive voice and text trading assistants risk unbounded LLM inference costs, abuse by unauthenticated users, and regulatory classification as investment advisors.

2. Decision

We implemented an enterprise bulkhead proxy with authenticated tier gating (Enterprise/Pro only), strict token buckets, Web Speech API integration, graceful telemetry excuses during degraded data freshness, and mandatory non-advisory legal disclaimers.

3. Consequences & Trade-Offs

Positive Outcomes

Protected API costs and infrastructure resilience under high conversational loads

Monetization protection: premium conversational telemetry reserved for paying tiers

Statutory immunity confirming Copilot outputs are purely descriptive econometric observations

Negative / Trade-Offs

Free-tier users cannot access conversational AI features

Mitigation Strategies

Clear upgrade prompt cards on the frontend guiding free users to subscription plans
