📋 Decision Context

Question:

How to implement multi-session support in Command Center for parallel task execution?

Task: Phase 3 of MCP Command Center enhancement - Multi-session support

🎯 Decision Made

Chosen:

Add activeSessions flash-persisted signal to track multiple concurrent sessions. Create currentSessionFilter signal with 'all' default. Add computed signals (filteredTasks, filteredAgents, filteredDecisions) for session-specific filtering. Add session selector dropdown in header with FormsModule ngModel binding. Update TaskState, AgentState, DecisionEvent interfaces to include sessionNumber field. Add CSS for session selector with hover/focus states.

Options Considered:

• No alternatives documented

💭 Reasoning

Multi-session support is critical for power users running multiple AI assistants simultaneously (e.g., one for frontend, one for backend, one for docs). The key insight: use computed signals for filtering rather than mutating arrays - this keeps reactivity intact and performance optimal. Flash-persistence for activeSessions ensures session history survives page refresh. The 'all' default shows everything by default, but users can drill down to specific sessions. SessionInfo interface tracks metadata (tasksCount, decisionsCount) for the dropdown. CSS uses --cc-accent for hover/focus to maintain visual consistency. Zero linter errors, ~80 lines added.
