Capabilities Introduced

Architectural Decisions

Three-tier sample rate engine (1-2s hot, 5-10s warm, cold) — balances live feel with CPU efficiency; active sessions poll fast, idle dashboards poll slowly
CSS-only visualizations — no JavaScript charting libraries required; pure CSS bar charts and sparklines keep the dashboard dependency-free
460 dashboard tests milestone — test coverage as quality gate for dashboard reliability; establishes continuous verification discipline for UI components
Planning quality scores — quantified metrics on plan-to-summary alignment, task completion rates, and decision capture completeness

Breaking Changes

None.
