PostHog loads after the page is idle through a same-origin /ingest proxy and follows the signed-in Convex user. Plausible uses the per-site script through a /pa proxy. Sentry keeps errors and traces only. Pages load only the @gib/ui modules they import, and client code reads public env from publicEnv.ts so zod stays out of the browser.
Every package moves to its newest in-major version, plus React 19.3, @convex-dev/auth 0.0.96 and next-plausible 4. The backend declares @auth/core and generates sign-in codes without oslo, which @convex-dev/auth no longer pulls in. The UseSend patch now actually removes the crypto import Convex refuses to bundle. The stricter react-hooks and typescript-eslint rules flagged the carousel, chart, image crop and mobile hook, which now pass.
