+## Roadmap
+
+### v0.3.0 — client-go integration
+
+Replace kubectl shell-outs with direct API calls via `client-go`.
+
+- [ ] Add `internal/kubeclient` package using `client-go` for:
+      - Context/namespace/label queries (faster than kubectl JSON parsing)
+      - Deployment list and rollout restart/status
+      - Secret fetch (AWS Secrets Manager via SDK, K8s secrets via API)
+      - ExternalSecret annotation update
+- [ ] Keep `internal/kubeexec` as fallback for operations not yet
+      covered by `client-go`
+- [ ] Remove `kind`/`k3d` integration test plan (client-go has its own
+      test coverage)
+- [ ] Add unit tests with `fake.Clientset` for the new package
+
+### v1.0 — Stable release
+
+Production-ready with package manager support and documentation.
+
+- [ ] Homebrew tap (`skoelle/homebrew-tap`) with `kctl-tui` formula
+- [ ] Scoop manifest (`skoelle/scoop-bucket`) for Windows
+- [ ] Full test coverage for `internal/kubeclient`
+- [ ] Documentation: architecture diagram, config reference, troubleshooting
+- [ ] Semantic versioning policy documented
+- [ ] Deprecation policy for config schema changes
