+Completion: Narratio now uses released ConfigKit v0.3.0. The implementation
+adds invocation-local pipeline discovery for isolated command tests and adjusts
+the integer party-version expectation to Narratio's unsupported-version
+diagnostic; it requires no operator configuration migration. The internal
+command-dependency inventory documents the new seam. No unreleased Narratio
+release note exists, and the immutable v2.0.0 note was not changed.

+- `git diff --check` — pass.
+- `gofmt -l` on the changed Go files — no output.
+- `scripts/build-release-assets.sh v0.0.0-test OUTPUT_DIR` — pass with
+  Linux amd64, Linux arm64, and macOS arm64 assets. The macOS result is
+  cross-build evidence only, not native runtime validation.
 
 Purpose: Establish a clean, reproducible handoff for later release preparation.
