Scheduling & Delivery

Cron-driven export scheduling with IANA timezone support, file or webhook delivery, retry with exponential backoff, and retention policies.

ExportJobSpec

Destinations

• File: Write to local path. RetentionPolicy enforces max_age_days, max_count, max_size_bytes.
• Webhook: HTTP POST with configurable auth_header, content_type, and timeout (default 30s).

Retry & Retention

• RetryPolicy: Exponential backoff via nerve-core::retry. Configurable max attempts and base delay.
• RetentionPolicy: Enforces max_age_days, max_count, and max_size_bytes. Old files auto-purged.
