AWS SQS

Async queues between the API and Lambda workers.

Used for

• Interview completed/failed — credit settlement after terminal interview states
• Report generate — trigger LLM report after successful settlement

API publishes; Lambdas consume with partial batch failure reporting and DLQs after retries.

Auth (env vars)

• INTERVIEW_COMPLETED_QUEUE_URL
• REPORT_GENERATE_QUEUE_URL
• AWS_REGION
• AWS_ACCESS_KEY_ID + AWS_SECRET_ACCESS_KEY — optional for local publish

Notes

• If queue URLs are unset, publish logs a warning and no-ops (no async settlement locally).
• Messages carry requestId as an attribute for log correlation.
• Invalid message schema is logged and dropped (not retried forever).
