+### Reports — Overview & Trends: "Avg Score by Facility" Contract filter
+
+The **Avg Score by Facility** card (chart) and the **Facility Score Comparison** table on `reports/index.html` share a **Contract** `<select>` (`#scoreContractFilter`) in the chart card header. It is **client-side only**: `reports.index()` attaches `project_id` + `contract` name to each `facility_scores` row and passes `score_contracts` (distinct `(project_id, name)` present, `0`/"No Contract" for unassigned). Selecting a contract filters both the Chart.js bars (`renderFacilityChart(pid)` mutates the existing chart) and the table rows (`.facility-score-row[data-project-id]`); default "All Contracts" shows everything. It does **not** reload the page or affect the top KPIs — only this section. Contracts shown are already role-scoped (customers/inspectors see only theirs).
+
 ### Reports — Phase R1: Issues Aging (`/reports/issues-aging`)
 
 Loads all non-resolved issues scoped by role, groups into five age buckets (`<24h`, `1–3 days`, `3–7 days`, `1–4 weeks`, `>4 weeks`). SLA status computed per-issue via `sla_status()`. Filters: severity, facility (both applied in Python after the main query to avoid double-outerjoin conflicts with customer scope).
