Danijel Martinek 9ff861667a chore(deps): backfill library traces for ADR-017 cluster
Adds approved trace files dated 2026-05-14 for all 13 OpenTelemetry
packages in packages/core-shared and packages/core-audit:

  @opentelemetry/api, api-logs, context-async-hooks,
  instrumentation, instrumentation-http, instrumentation-pg,
  instrumentation-undici, resources, sdk-logs, sdk-metrics,
  sdk-node, sdk-trace-base, semantic-conventions

All files pass validateTrace() from schema.mjs. The @sentry/opentelemetry
bridge was already covered in the ADR-014 cluster commit.

## Filter: license
<!-- Result: Apache-2.0 -->
`npm view @opentelemetry/instrumentation-pg license` returns `Apache-2.0`. Apache-2.0 is on the allowlist.
## Filter: types
<!-- Result: native -->
`@opentelemetry/instrumentation-pg` 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 the OpenTelemetry community as the first-party PostgreSQL (`pg`) instrumentation plugin. The 0.50.x line is current and tracks the OTel SDK release cycle.
## Filter: boundary-fit
<!-- Result: pass -->
ADR-017 §11 explicitly enables pg auto-instrumentation in `initOtelServerNode` with `enhancedDatabaseReporting: false` to prevent SQL statement capture (PII protection for WHERE clauses). Restricted to `core-shared/instrumentation/otel/` init paths.
## Filter: shadow-check
<!-- Result: pass -->
`@opentelemetry/instrumentation-pg` is the standard OTel PostgreSQL auto-instrumentation. No competing database span emitter is present in the workspace.
## Filter: eu-residency
<!-- Result: n/a -->
`@opentelemetry/instrumentation-pg` is a pure instrumentation plugin with no independent data transmission. Spans are routed through the configured OTel exporter. EU residency is governed by the exporter configuration.
## Filter: cve-scan
<!-- Result: clean -->
`pnpm audit --audit-level=moderate` reports no advisories against `@opentelemetry/instrumentation-pg` at the time of this trace.
## Filter: named-consumer
<!-- Result: pass -->
`packages/core-shared/src/instrumentation/otel/init-otel-server-node.ts` registers `PgInstrumentation` with `enhancedDatabaseReporting: false` (ADR-017 §11, R32). This emits database spans for every Payload CMS PostgreSQL query without capturing full SQL text that may contain PII.
## Prompt: replaces
Manual database span wrapping around every `pg` query call site. The auto-instrumentation patches the `pg` module to emit spans automatically, including connection pooling and query timing data.
## Prompt: migration-cost-out
Low. `PgInstrumentation` is registered in one init file. Removing it means disabling the plugin and optionally adding manual spans at `pg` query call sites — localized to the SDK init.
## Prompt: alternatives-considered
1. **Manual pg spans** — No plugin needed, but requires wrapping every Payload CMS / pg query explicitly. Rejected: Payload's query layer abstracts away direct `pg` calls, making manual wrapping impractical without forking Payload internals.
2. **`pg-monitor` or query logging middleware** — Log-based approach with no OTel integration. Rejected: produces log entries outside the trace pipeline, losing span correlation.
See ADR-017 for the full decision rationale.
