+The stage result contract has one analyze-specific projection boundary. On
+success, the runner validates and deep-copies the complete reconciled session
+collection and the invocation subset. Aggregate session outputs are rebuilt in

+limited to current records produced by that invocation's run ID. Ordinary
+stage outputs cannot accompany this projection, so there is one source of

+Analyze may return a projection together with an error. That restricted result
+cannot carry ordinary outputs, skip state, aggregate logs, generated configs,
+or metadata. The runner persists only the validated per-artifact collections,
+then marks the aggregate analyze and run state failed and invalidates delivery
+dependents conservatively. Unrelated current records survive because the
+session projection is complete. A malformed projection is not applied, and a
+failed session projection save restores the prior per-artifact authority before
