## Filter: license

<!-- Result: MIT -->

`npm view @sentry/opentelemetry license` returns `MIT`. MIT is on the allowlist.

## Filter: types

<!-- Result: native -->

`@sentry/opentelemetry` is authored in TypeScript and ships its own `.d.ts` declaration files. No separate `@types/` package is needed.

## Filter: maintenance

<!-- Result: active -->

Actively maintained by Sentry Inc. as the official bridge between the Sentry SDK and the OpenTelemetry SDK. Versions track the `@sentry/*` SDK family; the 10.x line is current.

## Filter: boundary-fit

<!-- Result: pass -->

ADR-014 designates Sentry as the error-capture backend, and ADR-017 mandates OpenTelemetry as the instrumentation substrate. `@sentry/opentelemetry` is the bridge that wires Sentry as an OTel exporter — it belongs exclusively in `core-shared/instrumentation/sentry/` alongside the adapter pair. Feature packages MUST NOT import it directly (ESLint `no-restricted-imports`, ADR-014 §6).

## Filter: shadow-check

<!-- Result: pass -->

`@sentry/opentelemetry` is the only OTel-to-Sentry bridge in the workspace. No competing exporter bridge (e.g., manual `@opentelemetry/exporter-*` wired to Sentry) is present.

## Filter: eu-residency

<!-- Result: ok -->

`@sentry/opentelemetry` is a pure instrumentation adapter with no independent data transmission. All spans and log records it emits are forwarded through the Sentry SDK, which routes to the DSN host (EU-hosted if configured). EU residency is governed by the DSN setting, not this package.

## Filter: cve-scan

<!-- Result: clean -->

`pnpm audit --audit-level=moderate` reports no advisories against `@sentry/opentelemetry` at the time of this trace.

## Filter: named-consumer

<!-- Result: pass -->

`packages/core-shared/src/instrumentation/sentry/` is the sole consumer. It registers `@sentry/opentelemetry`'s `SentrySpanProcessor` and `SentryPropagator` during OTel SDK initialization so that all OTel spans are also captured as Sentry transactions.

## Prompt: replaces

Prior to ADR-017, the workspace had no OTel substrate. `@sentry/opentelemetry` replaces the need to configure two independent pipelines (a direct Sentry SDK pipeline and a raw OTel SDK pipeline) by letting a single OTel pipeline export to Sentry via the bridge.

## Prompt: migration-cost-out

Low. `@sentry/opentelemetry` is used in one file in `core-shared/instrumentation/sentry/`. Replacing Sentry as the exporter means swapping this bridge for a different `SpanExporter` in that single file. The OTel substrate (ADR-017) remains untouched.

## Prompt: alternatives-considered

1. **Direct Sentry SDK without OTel bridge** — Rejected in ADR-017: coupling feature packages to `@sentry/*` APIs directly would violate vendor isolation. The OTel-first approach keeps instrumentation portable.
2. **`@opentelemetry/exporter-zipkin` / Jaeger** — Open-source trace backends considered but lack Sentry's session replay, error deduplication, and release tracking. Sentry via bridge offers a superset.

See ADR-014 and ADR-017 for the full decision rationale.
