/**
 * Integration tests for pipeline-autonomous.ts — requires Postgres.
 *
 * Tests focused on:
 * 1. AUTONOMOUS_SIGE_PIPELINE_ID constant value
 * 2. Resume dispatcher routing: a run with pipeline_id='autonomous-sige'
 *    routes to runAutonomousSige (not runIdeasPipeline) in resumeRunById
 *    and resumeAllInterrupted.
 * 3. The pipeline_run row gets the correct pipeline_id when a run is created
 *    via acquirePipelineLock with AUTONOMOUS_SIGE_PIPELINE_ID.
 *
 * NOTE: We do NOT call runAutonomousSige end-to-end here because it
 * requires a live Mem0 + LLM stack. Instead we test the observable
 * integration contracts: store shape and dispatcher routing.
