What

Make orchestrion diagnostics-channel instrumentation the default in @sentry/node and remove the experimentalUseDiagnosticsChannelInjection() opt-in.

Why

The channel-based instrumentations shipped opt-in in v10. Making them the default in v11 unlocks instrumentation at run and build time.

Removal of the vendored OTel/IITM code is intentionally out of scope; it is tracked separately as follow-up.

Closes: #22345

Make orchestrion diagnostics-channel injection the default in `@sentry/node`
and remove the `experimentalUseDiagnosticsChannelInjection()` opt-in.

`Sentry.init()` now installs the channel-injection module hooks unconditionally
when span recording is enabled, so the opt-in function, its loader indirection,
and the name-based OTel->channel integration swap are gone. The self-selecting
`dataloader` and `knex` integrations pick the channel path automatically now
that `isOrchestrionInjected()` is true by default.

Redis stays a composite integration: the native diagnostics-channel subscribers
(node-redis >=5.12, ioredis >=5.11, batches) plus the orchestrion subscribers
for the older ranges, all sharing the node cache `responseHook`. The vendored
OTel patchers only run on runtimes without `tracingChannel` (Node <18.19).

BREAKING CHANGE: `experimentalUseDiagnosticsChannelInjection()`,
`diagnosticsChannelInjectionIntegrations()`, `isDiagnosticsChannelInjectionEnabled()`
and `applyDiagnosticsChannelInjectionIntegrations()` are removed from
`@sentry/node`. Channel-based instrumentation is now always on; no opt-in call
is needed.

// No-op otherwise.
return applyDiagnosticsChannelInjectionIntegrations(integrations, options);
export function getDefaultIntegrations(_options: Options): Integration[] {
return [...getDefaultIntegrationsWithoutPerformance(), awsIntegration(), awsLambdaIntegration()];

AWS serverless drops performance integrations

High Severity

Removing applyDiagnosticsChannelInjectionIntegrations from getDefaultIntegrations leaves @sentry/aws-serverless defaults without any auto-performance integrations when tracing is on. Sentry.init() still registers orchestrion hooks, but the slim default list never includes channel subscribers such as postgresIntegration() or expressIntegration(), so Lambda apps lose DB and framework spans that the opt-in path used to append.

Forward build-resolved tracingHooksDir in @sentry/nextjs server init so bundled
pnpm apps load the channel-injection hook.
Update span origins to orchestrion values (koa, hapi, nestjs, firebase functions)
and add error.type to errored express request_handler spans.
Skip preload and bring-your-own-OTel apps (node-express-cjs/esm-preload,
node-otel-sdk-node, node-otel-custom-sampler); fixme AI (ai@v3), trpc, and
firebase functions tests pending follow-ups.

The channel-based Express integration only resolved the route for
request_handler layers, so routes served through mounted middleware
(app.use('/trpc', handler)) never set http.route on the root span and their
transactions kept the raw URL name. Compute the matched route for every layer
type, mirroring the OTel Express integration's per-layer route resolution.

Re-enables the previously fixme'd trpc tests in node-express, tsx-express and
node-express-v5.

Next env tracing skips hooks dir

Medium Severity

The early registerDiagnosticsChannelInjection({ tracingHooksDir }) call is gated on hasSpansEnabled(opts), but opts does not resolve SENTRY_TRACES_SAMPLE_RATE the way @sentry/node init does via getTracesSampleRate. When tracing is enabled only through that env var, Next skips registration with tracingHooksDir, while nodeInit still enables channel injection using the bare specifier—often failing for bundled Next server builds that need the build-time hooks path.
