chore: remove Nix and the std deployment framework#1699
Merged
Conversation
Remove all Nix tooling and the std (divnix/standard) framework, which are no longer used: - flake.nix / flake.lock and the entire nix/ tree (cardano-services k8s deployments, OCI images, operables, terraform outputs, kubeconfigs) - std workflows (std.yml, std-release.yaml, std-unexploded.yml) and the Nix-based cardano-services deploy workflow - the yarn-plugin-nixify plugin and the generated yarn-project.nix - treefmt.toml (Nix-only formatter config), .envrc / direnv, and the prj-spec .gitignore entries Drop the now-obsolete yarn-project.nix references from the unit-test workflow's "Generated files" step, the Dockerfile COPY layer, the npm version script, and the README config-update instructions. yarn install --immutable remains clean without the nixify plugin.

Summary
Removes all Nix tooling and the std (divnix/standard) framework from the repo — no longer needed. 40 files deleted, 6 surgically edited;
yarn.lockis untouched.Deleted
flake.nix,flake.lock, and the entirenix/directory — including the cardano-services Kubernetes deployment infrastructure (deployments/*.nix,oci-images.nix,operables.nix,packages.nix, terraform outputs, kubeconfigs,local/*)..github/workflows/std.yml(jobscheck-yarn-project-nix,discover,images,diff,deploy),std-release.yaml,.github/std-unexploded.yml..github/workflows/cardano-services.yaml(wasnix run .#cardano-services...)..yarn/plugins/yarn-plugin-nixify.cjsand the generatedyarn-project.nix.treefmt.toml(Nix-only formatter config;treefmtwas invoked only via the flake),.envrc/.envrc.local.example(direnv).Edited (surgical)
.yarnrc.yml— drop theyarn-plugin-nixifyplugin entry..github/workflows/continuous-integration-unit-tests.yaml— remove the "🔨 Generated files" step (it only restored/verifiedyarn-project.nix).build_and_testitself is unchanged.Dockerfile— dropyarn-project.nixfrom theCOPYlayer.package.json—versionscript no longergit addsyarn-project.nix..gitignore— remove the# created by nix(result,source),# direnv(/.direnv,.envrc.local), and numtideprj-specblocks.README.md— remove the "Withnix" config-update instructions (theyarnvariant remains).Notes for reviewers
masterareblock-fixupandbuild_and_test (ubuntu-22.04)— neither is removed. The now-deletedcheck-yarn-project-nix/discoverchecks are not required, so merges aren't affected.yarn install --immutableverified clean without the nixify plugin (yarn.lockunchanged).🤖 Generated with Claude Code
