+Stage 13's ownership-transfer implementation, tests, runner documentation, and
+decision evidence are committed at `80aecb6` (`Reuse prepared execution
+snapshot ownership`). The completed local scope maps to the accepted roadmap as
+follows:
+
+- Item 1's ConfigKit performance request remains recorded at `d53021e`; no
+  upstream implementation or dependency update was included.
+- Items 2–5 are implemented in validation, rendering, request encoding, and
+  artifact reading. Their before/after fixtures, measurements, and focused
+  verification appear in the corresponding execution-evidence sections.
+- Item 6's ownership review selected the simpler private-payload transfer in
+  Stage 13. It retains nested-extra and details copies; source isolation,
+  invalid-copy classification, allocation savings, and fixed-batch heap
+  observations are recorded above.
+- Item 7's lightweight prompt/profile selection and requirement inspection are
+  implemented and measured in the inspection evidence sections. Production
+  compiled rendering and assembled offline preparation/execution benchmarks
+  are also maintained and recorded.
+
+The canonical runner document describes the new snapshot ownership mechanics.
+The source/validation and model-client documents remain consistent with their
+implemented flows; no package responsibility, public API, or format semantics
+changed. This plan remains the implementation record, and the performance
+roadmap's status now reflects completion rather than proposed work.
+
+Final verification passed on the Stage 13 code: `go test -race -vet=off
+-mod=readonly ./...`, `go vet -mod=readonly ./...`, and
+`python3 scripts/check-examples.py` (prepare, run, observe). The changed Go
+files were `gofmt`-clean, and changed-file Markdown local targets were checked
+separately. These checks are local correctness and documentation validation;
+they do not add a release gate or imply provider-latency improvement.
