  1. Capture the exact failure state

    Reversible

    Record whether the feature is absent, disabled, powered but unresponsive, or showing a message. Expected behavior: authorize the correct account and install a compatible app with enough space.

  2. Isolate the component boundary

    Reversible

    Try a free known-compatible app and inspect the exact download message. Test the simplest supported configuration with unrelated accessories and optional services removed. Boundary to separate: one app versus account billing, storage, region, network and OS compatibility.

  3. Correct only the proven cause

    Reversible

    Correct account terms/payment, free space or update iOS before retrying. Restore only the failed prerequisite or path; do not change working layers.

  4. Verify and stop safely

    Reversible

    Repeat from a cold start and complete one normal use. Do not remove the only authenticator or banking app without recovery access.
