Engagement disposition: evolving. Main partially answers the data-scientist concern: docs/distribution-instrumentation.md names analytics-engine outputs and data/engagement-metrics.json exists, while docs/data-contract-surfaced-items.md documents surfaced-item input fields. I did not find a dedicated analytics-engine data schema reference on main; PR #27 adds docs/analytics-engine-data-contract.md but is red on data drift.
