- Externalize inline images in messages and run events before persistence
- Keep snapshots, transcripts, and metadata free of inline payloads
- Serialize messages after externalization to reduce peak memory usage
- Preserve live messages, URL-only images, and SDK image retrieval behavior
- Add regression tests for deduplication, redaction, storage failures, and serialization order
Every host step now opens a stage scope, so observations recorded inside it (including cross-task plugin/RPC calls resolved through the execution registry) carry the owning step as parent; the pipeline lane records its own pipeline/run node so acks and replies issued outside the runner still hang off a node.
