linting Shipped
What this lens looks for
Linting configured from day one on every project; linter config committed to repo; linting runs as part of build or pre-commit; formatting must be auto-fixable via a single command (SwiftLint/swift-format, ktlint, ESLint/Prettier, Roslyn+dotnet format)
What its verifier checks
Linter config file present and committed; lint runs in CI; no lint errors suppressed inline without justification; formatter command documented in README or Makefile
