Agent Trajectory Observability Format (ATOF) JSONL exporter support for NeMo Flow.

The [`AtofExporter`](/reference/api/rust-library-reference/nemo-relay/observability/atof/struct-atofexporter) registers as an event subscriber and writes each canonical NeMo Relay Agent Trajectory Observability Format (ATOF) event as one JSON object per JSONL line.

## Structs

* [AtofExporter](/reference/api/rust-library-reference/nemo-relay/observability/atof/struct-atofexporter): Filesystem-backed Agent Trajectory Observability Format (ATOF) JSONL event exporter.
* [AtofExporterConfig](/reference/api/rust-library-reference/nemo-relay/observability/atof/struct-atofexporterconfig): Configuration for [`AtofExporter`](/reference/api/rust-library-reference/nemo-relay/observability/atof/struct-atofexporter).
* [AtofFileSinkConfig](/reference/api/rust-library-reference/nemo-relay/observability/atof/struct-atoffilesinkconfig): Filesystem sink for raw ATOF JSONL events.
* [AtofStreamSinkConfig](/reference/api/rust-library-reference/nemo-relay/observability/atof/struct-atofstreamsinkconfig): Streaming sink for raw ATOF events.

## Enums

* [AtofEndpointFieldNamePolicy](/reference/api/rust-library-reference/nemo-relay/observability/atof/enum-atofendpointfieldnamepolicy): Field name transformation policy used before sending events to an endpoint.
* [AtofEndpointTransport](/reference/api/rust-library-reference/nemo-relay/observability/atof/enum-atofendpointtransport): Streaming transport used by an ATOF endpoint.
* [AtofExporterError](/reference/api/rust-library-reference/nemo-relay/observability/atof/enum-atofexportererror): Errors produced while configuring or operating the ATOF JSONL exporter.
* [AtofExporterMode](/reference/api/rust-library-reference/nemo-relay/observability/atof/enum-atofexportermode): File write behavior for [`AtofExporter`](/reference/api/rust-library-reference/nemo-relay/observability/atof/struct-atofexporter).
* [AtofSinkConfig](/reference/api/rust-library-reference/nemo-relay/observability/atof/enum-atofsinkconfig): One destination for raw ATOF events.

## Type Aliases

* [AtofEndpointConfig](/reference/api/rust-library-reference/nemo-relay/observability/atof/type-atofendpointconfig): Backward-compatible name for an ATOF stream sink.
* [Result](/reference/api/rust-library-reference/nemo-relay/observability/atof/type-result): Result type for the ATOF JSONL exporter.
