Latest change 7aca7a5d40dbb0a5761570d32fa9e38d2396e162 - feat: automate managed workspace provisioning with health checks, version snapshots, backup verification, and domain assignment (AKURAI-PLATFORM-9) by Ólafur Búi Ólafsson

/**
 * payment/provisioning.ts — Managed workspace provisioning executor
 *
 * Drives a provisioning request from "entitled" to "ready" by:
 * 1. Assigning a workspace domain
 * 2. Advancing to installing state
 * 3. Verifying each app's health and recording deployed release versions
 * 4. Recording backup verification
 * 5. Marking domain, workspace, and installations as active/installed
 *
 * A failure at any step marks the provisioning as "failed".
 * The request remains safely retryable.
