      # Why: pnpm's bundled node-gyp ships gyp_main.py without execute
      # permission, which breaks native module builds (e.g. node-pty's
      # postinstall) with "/bin/sh: gyp_main.py: Permission denied".
      # Pin the fallback to the lockfile's node-gyp version so CI stays
      # reproducible while forcing pnpm to bypass its broken bundled copy.
      # Gate on runner.os == 'Linux' to match release.yml — the
      # npm-global path layout this step assumes is POSIX-shaped, and the
      # failure has only been observed on Linux runners. Today this job
      # pins runs-on: ubuntu-latest so the guard is a no-op, but it
      # prevents a silent break if a Windows/macOS matrix is added later.

        # Why: pnpm 10.24's frozen headless fast path can fail on fresh Ubuntu
        # runners while creating the root node_modules. Use the normal resolver

      # Why: oxlint fails any file over max-lines that is NOT suppressed, so this
      # ratchet forbids ADDING a new suppression (inline disable or mobile max
      # bump). Existing oversized files are grandfathered in
      # config/max-lines-baseline.txt, which may only shrink — new bypasses fail
      # here with a clear message instead of silently growing the debt.

      # Why: project-owned type declarations must live in .ts so tsc
      # actually checks them. TypeScript's skipLibCheck: true (inherited
      # from @electron-toolkit/tsconfig) silently widens unresolved names
      # in .d.ts to `any`, which is how #1186 shipped a broken IPC signature
      # past typecheck. See docs/preload-typecheck-hole.md.

      # Why: real old Git diagnostics differ from mocked errors. Keep the
