Danijel Martinek f77e6ea881 chore(template): clean-slate template snapshot from bb4a0c7
Curated, product-agnostic snapshot of the post-story-04 tree: demo
content deleted, auth-only reference feature, web-next shell, all gates
green. Product-specific docs, ADRs 027-029, PRDs/epics/archive, editor
library traces, and product naming are curated out; generic template
repairs (coverage provider devDeps, root test:coverage script, live
lint fixes, root-only release-please) are kept. See TEMPLATE.md for
provenance, curation list, and usage.

## 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.
