/**
 * log10x_retriever_probe — end-to-end retriever chain verifier.
 *
 * Fires a synthetic query and asserts every stage of the chain (offload-bucket
 * freshness → indexer pipeline running → SQS queues drained → pod ready →
 * query submission → CloudWatch scan match → CloudWatch stream fetch → S3
 * qr/*.jsonl write → MCP-side events returned). Each stage is a named assert
 * with a one-line `observed` summary and a stored remedy keyed on the assert
 * name.
 *
 * Use as a deep doctor diagnostic OR as the post-install verify step.
