adk_trace_event (erlang_adk v0.10.0)

View Source

Metadata-only projection for developer trace retention.

The trace store accepts the already-versioned observability and workflow lifecycle schemas, but deliberately applies a narrower persistence policy: prompt, response, media, tool argument, and result fields are never retained. The default policy rejects a content-bearing event. A trusted local owner may instead configure prune, which removes those fields and marks the retained wrapper without weakening either source schema validation.
