Tenant Health Score: - CoverageSnapshot table stores daily health metrics (parser %, MITRE %, firing %) - _compute_health() weighted formula: 40% parser coverage + 35% MITRE + 25% firing (reweighted 55/45 when firing cache empty) - GET /api/coverage/health returns score + delta vs previous snapshot - GET /api/coverage/snapshots returns chronological history for sparklines - POST /api/coverage/snapshot for manual recording - Auto-snapshot recorded at end of every sync-sources call - Overview dashboard: prominent health score card with color coding, component breakdown, delta indicator, and inline SVG sparkline (last 30 points) Rule Dependency Map: - GET /api/coverage/dependency-map flips the coverage map — rule → required sources - Each source flagged healthy/inactive/no_parser; at_risk = any source missing - New section on Threat Coverage tab with at-risk filter toggle PowerQuery Playground: - New query.py router: GET /presets (7 curated queries) + POST /run - New Query nav tab with time-range pills, preset buttons, localStorage history, monospace textarea, auto-column results table, client-side CSV export Onboarding Tracker: - GET /api/coverage/onboarding-status returns per-source pipeline progress across 6 stages: Data Received → Parser File → Parser Active → Source Labeled → Detection Rules → Rules Firing - New section on Onboarding tab with emoji stage dots, progress bars, collapsed completed sources with show/hide toggle Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
