+## Go Minimum And Release Toolchain
+
+ReleaseKit provides reasonable support for routine build and release needs,
+following [ADR 0002](../adr/0002-routine-releases.md). Its Go support policy relies
+on upstream compatibility commitments and verification proportionate to those
+needs.
+
+Select the Go series during release preparation. When advancing the consumer
+minimum, use the latest locally available stable series and record its initial
+stable version in `go.mod`, such as `go 1.26.0`. Use a higher patch minimum when
+a dependency requirement or identified correctness fix requires it. Minimum
+increases follow the versioning and compatibility rules above and are explained
+in the release note.
+
+Build the maintainer release executable and validate the candidate with the
+same latest locally available patch of the selected series. Keep that toolchain
+active throughout preparation, tool bootstrap, and validation, using local
+toolchain selection. Maintained CI images follow the chosen build toolchain.
+The patch used for these operations is separate from the consumer minimum.
+
+Successful build and release validation on that patch serve as sufficient
+evidence of support from the series' initial stable release through subsequent
+patch releases, subject to known dependency requirements or correctness issues.
+This relies on Go's [release policy](https://go.dev/doc/devel/release#policy) and
+[compatibility commitments](https://go.dev/doc/go1compat). Additional
+patch-specific validation is warranted by concrete evidence; routine releases
+require no patch-version matrix. Record the actual validation toolchain in the
+release evidence.

+Choose an unused stable `vMAJOR.MINOR.PATCH` version, and add

 the exact version. Summarize the change and any compatibility or upgrade impact.
