• npx eslint src/pages/Processes.jsx src/pages/Processes.test.jsx src/api/resources/process_instance.js src/api/resources/process_instance.test.js src/state.js src/state.test.js
• npx vitest run src/api/resources/process_instance.test.js src/state.test.js src/pages/Processes.test.jsx
• npx vitest run --maxWorkers=4
• npm run build
• Browser smoke: http://127.0.0.1:5176/processes/proc:1/instances reached the login boundary with no console errors

Local note

• npx vitest run without worker limiting reported Vitest fork-runner timeouts locally after all 447 tests had passed; the constrained full-suite run above passed cleanly.
