Context is not fully globally accessed? [ probably newbie question ]

const trpc = initTRPC.context<{
    userSession: { id: string, authenticated: boolean }
}>().create();

const baseProcedure = trpc.procedure.use((opts) => {
    opts.ctx = {
        userSession: {
            id: 'dummy',
            authenticated: false
        }
    };

    return opts.next()
});
const protectedProcedure = baseProcedure.use((opts) => {
    // ctx is undefined
    if (!opts.ctx.userSession.authenticated) {
        throw new TRPCError(
            { code: 'UNAUTHORIZED', cause: 'because!' }
        );
    }
    return opts.next();
});
