Expose fix, verify, test, and help through consistent Make targets, with locked uv tools, EditorConfig, versioned hooks, shared binary checks, and generated agent file indexes. Apply safe lint fixes and formatting quietly while preserving diagnostics and failure exit codes. Require Go 1.26 and read CI toolchains from go.mod. Track lint and license tools in the root module; run pinned actionlint separately because of YAML dependency conflicts. Run vet through golangci-lint and retain distinct compile/link and module-tidiness checks. Refresh Actions and share setup where applicable. Ignore Codecov and coverage artifacts on Unix and Windows while keeping plain Git status checks for tracked changes and unexpected output. Run portable runtime and static checks together on Ubuntu while retaining downstream host, devices, and cmd consumer gates. Validation: make fix and make verify pass. Applicable test, generation, race, cross-build, and consumer checks passed during implementation. Formatter diagnostic fixtures, ignore-rule fixtures, index checks, and staged hooks pass. Native hosted OS and physical hardware execution remain outside local validation. Squashing preserves the validated file tree exactly.
