A CLI that treats Figma files like source: semantic diffs between versions, component and style inventories with usage counts, version-pinned cached fetches, and verified webhook watch events — all over the public REST API.

Describe env vars, domains, and crons in a versioned state file, then pull, validate, plan, drift-check, and apply with policy enforcement, restore-point snapshots, and a double-safe write posture.

Correlates deployments, environment drift, error rates, and traces into ranked root-cause findings — then prints a dry-run remediation plan of exact vercel commands. It diagnoses and recommends; it never executes writes.
