release v4.1.0 -- platform release The standardization spec for the nomograph estate. Pipeline graduates from CI catalog to platform. - Default platform policy applied uniformly via default block: retry, 30m timeout, interruptible. - Six universal gate components: hygiene, license-policy, readme-shape, release-discipline, registry-coherence, deps-scan. - Ten language meta-components composing the universal gates with language-specific lint/test/publish: tool-rust, lib-rust, tree-sitter, grammar-rust, python-bench, python-lib, worker-ts, latex-template, data-only, go-tool. - New container images: python, go-tool, worker-ts. - Container builds and release tagging are decoupled. Container builds run only on Containerfile change / schedule / on-demand. Tag pipelines run a fast retag stage that re-tags :latest as :vN.M.P per container in ~30s each, ~5 min total. - Pre-v4 components remain available for one release window. v4.0.0 tag exists in history but never released cleanly. v4.1.0 ships as the platform release; consumers should never pin to v4.0.0. See CHANGELOG.md for the per-language migration recipe.
