  8. Platform API Deprecation advanced

    The platform is removing v1 of its config API. Telemetry showed 412 calling services at announcement; after six months of a funded migration 9 remain - 4 have no owner in the catalogue, 3 are monthly batch jobs that touch the API only on the first of the month, and 2 belong to a team that says it will not move this quarter. Removal was promised for the end of the quarter. Sequence the removal so you keep the date and stay reversible at every step.

  12. Platform APIs intermediate Multiple choice
