#166) libdatadog's automatic entity detection (libdd-common's entity_id module) is gated #[cfg(unix)] and therefore inert on the wasm32 target, and DD_EXTERNAL_ENV is unreachable from wasm, so the native exporter never sent Datadog-Container-ID / Datadog-Entity-ID / Datadog-External-Env. Node can read /proc and process.env, so detect them in the HTTP transport and rewrite the Rust-rendered request head to carry them — the headers native libdatadog adds via set_standard_headers. Detection mirrors dd-trace-js's exporters/common/docker.js (the proven legacy exporter path) and libdd-common's compute_entity_id (ci-<container_id> else in-<cgroup_inode>). The empty datadog-container-id libdatadog emits on wasm is replaced rather than duplicated, and external-env is rejected if it carries CR/LF or non-ASCII to avoid header injection.
