# telemetry/ English | [δΈ­ζ–‡](README.zh.md) Outbound session reporting: the telemetry seam plus its OpenTelemetry backend. The design β€” the boundary axiom (the harness's aspect ends at `emit()`; delivery is the reporting SDK's), the `telemetry/record` waterfall (deployment-mounted redaction rules; the seam ships none), the fixed chunk projection, the handoff cursor, and the operational-record channel β€” is pinned in [the revival Agent Note](../../.agents/notes/implemented/feature/2026-07-23-session-telemetry-otel-revival.md). | Package | Role | |---|---| | [`@deepseek-ai/dsh-session-telemetry`](session-telemetry/) | The seam: capture points, projection, redaction, handoff cursor, ops signals, and the minimal backend contract (`emit`/`flush?`/`shutdown`). | | [`@deepseek-ai/dsh-session-telemetry-otel`](session-telemetry-otel/) | The backend a deployment loads: the OTel JS SDK's log pipeline (`LoggerProvider` + `BatchLogRecordProcessor` + OTLP/HTTP exporter), configured verbatim through passthroughs. |
