+## ADDED Requirements
+
+### Requirement: Heartbeat carries observed gateway telemetry
+Every authenticated `GatewayHeartbeat` SHALL carry the bounded process-level counters, delay totals and samples, control RTT/loss/jitter, pending reliable work, reconnect count, and provider state defined by `GatewayTelemetry`.
+
+#### Scenario: Valid telemetry heartbeat
+- **WHEN** a gateway reports its current observed snapshot
+- **THEN** Go, Rust, and Swift bindings accept the same bounded low-cardinality values and units
+
+### Requirement: Heartbeat telemetry excludes sensitive dimensions
+Heartbeat telemetry MUST reject unknown fields and MUST NOT include session, route, endpoint, credential, label, or payload values.
+
+#### Scenario: Secret or high-cardinality field is attempted
+- **WHEN** a heartbeat contains an unregistered session, route, endpoint, credential, or payload field
+- **THEN** strict contract validation rejects it before authenticated transport
