+# Seal of Reliability on Feed Detail Page (#141)
+
+## Overview
+In accordance with [Issue #141](https://github.com/MobilityData/mobilitydatabase-web/issues/141), this feature integrates the Seal of Reliability badging and evaluation summary into the GTFS Feed Detail page.
+
+## Key Capabilities
+- **Feed Detail Header Badge**: Displays `SealOfReliabilityChip` when `config.enableSealOfReliability` is enabled.
+- **Direct Navigation**: Clicking the badge navigates users directly to the comprehensive reliability analysis view (`/feeds/{feedDataType}/{feedId}/seal-of-reliability`).
+- **Loading & Error States**: Graceful fallback with tooltips and warning banners when reliability reports are unavailable or evaluating.
+- **Criteria Evaluated**:
+  - Availability (historical dataset snapshot uptime)
+  - Compliance (canonical GTFS validator notice severity)
+  - Freshness (feed update recency)
+  - Continuity (long-term data availability)
