# Specification: Session Context Snapshots & Visibility

## 1. Overview
This track focuses on transitioning from global context management to explicit session-scoped context. It introduces transparent visibility into the exact context (system prompts, aggregated markdown, files, and screenshots) used in a session, allows saving context selections as reusable presets, and adds MMA dashboard integration for filtering session hubs by specific agents.

## 2. Functional Requirements

### 2.1 Context Presets & Assignment
- **Context Snapshots:** Users can save the current selection of files and screenshots as a named "Context Preset".
- **Preset Swapping:** Users can easily load a Context Preset into an active session.
- **MMA Assignment:** Allow assigning specific Context Presets to individual MMA agent personas, preventing all agents from having access to all files by default.

### 2.2 Transparent Context Visibility
- **No Hidden Context:** The Session Hub must expose the exact context provided to the model.
- **Initial Payload Visibility:** The aggregated markdown content generated at the start of the discussion must be viewable in the UI.
- **System Prompt State:** Display the fully resolved system prompt that was active for the session.
- **Injection Timeline:** The UI must display *when* specific files or screenshots were injected or included during the progression of the discussion.

### 2.3 Agent-Focused Session Filtering
- **Dashboard Integration:** Move the "Focus Agent" feature from the Operations Hub to the MMA Dashboard.
- **Agent Context Filtering:** Add a button on any live agent's panel in the MMA Dashboard that automatically filters the other hubs (Session/Discussion) to show only information related to that specific agent's session.

## 3. Acceptance Criteria
- [ ] Context selections (files/screenshots) can be saved and loaded as Presets.
- [ ] MMA Agent Personas can be configured to use specific Context Presets.
- [ ] The Session Hub displays the generated aggregate markdown and resolved system prompt.
- [ ] The discussion timeline clearly shows when files/screenshots were injected.
- [ ] The MMA Dashboard allows focusing the UI on a specific agent's session data.
