* chore(ai-workflow): track repo-managed review tooling * fix(ai-workflow): remove repo-specific path assumptions Make shared workflow hooks and APK testing guidance resolve paths from the repo and contributor environment so the tooling works for all contributors, not just one machine.

Initialize App Once, Not Per Mount
Do not put app-wide initialization that must run once per app load inside useEffect([]) of a component. Components can remount and effects will re-run. Use a module-level guard or top-level init in the entry module instead.
Incorrect (runs twice in dev, re-runs on remount):
function Comp() {
useEffect(() => {
loadFromStorage()
checkAuthToken()
}, [])
// ...
}
Correct (once per app load):
let didInit = false
function Comp() {
useEffect(() => {
if (didInit) return
didInit = true
loadFromStorage()
checkAuthToken()
}, [])
// ...
}
