chore: migrate binary cache from garnix to cachix - #88
Merged
Conversation
garnix is down, so move the flake's substituter config and the NixOS system substituter config to the chadac-dotfiles Cachix cache. Add a GitHub Actions workflow that builds the odin/thor NixOS and home configurations and pushes them to Cachix (replacing garnix's automatic server-side builds).

Drop garnix.yaml so garnix no longer runs builds/checks on this repo. Builds are now handled by the Cachix GitHub Actions workflow. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Full NixOS/home closures exhausted the GitHub runner's disk
("No space left on device"). Reclaim ~25GB of preinstalled tooling
before building.

Bump nixpkgs (2026-05-23 -> 2026-07-20) and all other flake inputs (home-manager, emacs-overlay, nix-darwin, mise, flake-parts, determinate nixpkgs-weekly). Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>

Regenerate lockfile after merging origin/nix-config so all inputs (nixpkgs, home-manager, emacs-overlay, nix-darwin, mise) are current. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The nixpkgs bump broke two flake checks: - waylandDisplayTests: pkgs.nixt is no longer the test-framework function. The test file already uses lib.runTests, so invoke it directly and fail the build on any test failure. - fullSystemTest: nixpkgs.hostPlatform/overlays are now read-only per test node. Supply node.pkgs with the emacs-overlay + allowUnfree and drop hardware-configuration.nix (the driver provides VM hardware), avoiding the read-only collisions. Also remove renovate.json (unused).

Summary
garnix is down, so this migrates the binary cache from garnix to the
chadac-dotfilesCachix cache.flake.nix— replace the garnix substituter/public-key innixConfigwithhttps://chadac-dotfiles.cachix.org(FlakeHub & Determinate entries kept).apps/default.nix— same swap in the NixOS systemnix.settings.substituters..github/workflows/cachix.yml(new) — build theodin/thorNixOS toplevel and home activation packages in a matrix and push results to Cachix viacachix/cachix-action. This replaces garnix's automatic server-side builds.The public signing key (
chadac-dotfiles.cachix.org-1:X6SN8xFOL7yHXvmFHDfYLAQy0U4E6qgq+2wlOLwTc1c=) was pulled from the live Cachix API.Follow-ups
