product_selection_deferred: true
functional_requirements:
  - Accept authenticated HTTPS requests containing an event payload.
  - Validate, durably enqueue, and asynchronously process accepted events.
  - Persist raw event records for replay and audit.
  - Expose an operational health endpoint and structured application logs.
  - Support separate development and production environments through variables.
non_functional_requirements:
  - Target at-least-once delivery with idempotent consumers.
  - Provide regional high availability for managed serving and messaging components.
  - Encrypt data in transit and at rest using managed encryption by default.
  - Scale ingestion and processing independently based on request and backlog load.
  - Retain audit data for 30 days by default and make retention configurable.
  - Apply least-privilege service identities and observable failure handling.
constraints:
  - Deploy only into an existing Google Cloud project supplied by the operator.
  - Terraform must be planable without provisioning resources.
  - No application container image is built or deployed by this repository.
  - Product selection is explicitly deferred during discovery and recorded afterward.
assumptions:
  - The workload is regional and an initial single-region deployment is acceptable.
  - A container image is supplied by an external CI/CD pipeline.
  - The runtime can use OIDC/IAM authentication and publish to messaging.
  - Event consumers are idempotent and tolerate duplicate delivery.
open_questions:
  - What are the peak requests per second and payload size limits?
  - Which region, compliance boundary, and customer-managed key policy apply?
  - What downstream systems receive processed events?
  - What SLO, alert thresholds, and on-call escalation policy are required?
