 //! OpenTelemetry provider initialisation — ported from `pkg/trace/agent.go`.
 //!
-//! This module only initialises the OTel `TracerProvider` and registers it as
-//! the global OTel provider.  It does NOT touch the `tracing` subscriber — the
-//! bridge layer (`tracing-opentelemetry`) is added in `main.rs` when building
-//! the subscriber stack.
+//! Currently only the stdout exporter is wired up.  OTLP gRPC / HTTP support
+//! can be added once the opentelemetry-otlp 0.27 builder API is confirmed.
 //!
-//! Supported batchers (mirrors Go `kindJaeger` / `kindOtlpGrpc` / etc.):
-//! - `"jaeger"`   → OTLP gRPC (Jaeger v2 speaks native OTLP)
-//! - `"otlpgrpc"` → OTLP gRPC
-//! - `"otlphttp"` → OTLP HTTP
-//! - `"stdout"`   → pretty-print to stdout
-//! - disabled / empty endpoint → no-op
+//! To enable: set `Trace.Batcher = "stdout"` in config (any non-empty batcher
+//! with a non-empty endpoint also works; set `Trace.Disabled = true` to opt out).
