QA Gate (P0/P1) / Test affected app (pull_request) Has been cancelled
__root identify effect called posthog.reset() whenever `user` was falsy — which includes the brief window while the session resolves on every page load. After the signup hard-redirect this rotated the anonymous distinct_id, orphaning the pre-signup anonymous person that carries `user_signed_up` and first-touch `$initial_utm_*`. The later identify() then merged a fresh, empty anon id, so signups never linked to trial/payment (only ~16% stitched) and channel attribution read "(none)" for 100% of signups. - __root.tsx: gate the effect on isLoading and only reset() on a real identified -> anonymous transition (logout), tracked via a ref. Logout still resets via dashboard handleSignOut. - register.tsx: identify() within the still-active anonymous session before firing user_signed_up, so the anon->identified merge carries $initial_utm_* and attributes the signup (email flow; Google is handled on OAuth return).
