Marissa Interface Spec

Designing the primary user experience for Kai Hamil's first and most important client.

Core Principle: Marissa is client #1. The entire system exists to reduce her cognitive load and create space for the crowded table. If it doesn't serve her, it doesn't ship.

Three Access Tiers

1. Served User (Default)

Single questions, contextual answers. No system knowledge required. She asks naturally, gets what she needs.

2. Decision Partner

Multi-turn dialogue for logistics and priorities. Input on what matters, not how it works.

3. Systems Administrator

Ideally invisible to her. Kyle handles infrastructure, configuration, and maintenance. She never sees the wiring.

Input Priority

  1. Voice-first - Lowest friction. Natural speech, hands-free.
  2. Text secondary - Quick messages when voice isn't appropriate.
  3. Passive/contextual third - Proactive notifications based on calendar, location, patterns.
