        # Excludes the suites that need chromium, per-machine PNG baselines or a
        # quiet machine — see config/test-suites.ts for the list and the reason
        # behind each entry. Identical to what `npm test` runs locally.
        # Safe in CI: TmuxManager no-ops all shell commands under VITEST (test/setup.ts).
        run: npm run test:ci

      - name: Run xterm-zerolag-input package tests
        # Layers 1-3 of the predictive-echo suites (unit laws, fixture replay,
        # seeded fuzz): deterministic, no browser, no live server. Depends on
        # the ROOT `npm ci` above — workspaces hoist the package's vitest into
        # the root node_modules; do not add a separate install here.
        run: npx vitest run
        working-directory: packages/xterm-zerolag-input

# Note: three suites are excluded from CI, each with its own local runner:
#   npm run test:browser  Playwright + chromium (+ a live server, and a real
#                         codex binary for codex-predictive-echo)
#   npm run test:mobile   the above plus environment-specific PNG baselines
#   npm run test:perf     wall-clock benchmarks; need an otherwise idle machine
# config/test-suites.ts holds the globs; the configs derive from it so the
# exclusions here and those runners cannot drift apart. Everything else runs in
# the `test` job above, which is the same thing `npm test` runs.
