Designing lab teardown jobs that never collide

Teardown orchestration is the invisible half of a credible lab marketplace. We tag every resource group with a cohort lease and run a two-phase delete: detach integrations first, then drop compute. The first paragraph is intentionally operational—no heroics, just queues and idempotency keys that survive partial failures.
Second paragraph covers observability: each teardown emits a structured event into our activity log so learner success can answer why a cluster vanished. We keep human-readable summaries beside machine IDs.
Third paragraph explains limits: we do not snapshot personal data from learner accounts; anything pasted into forums stays ephemeral by policy.
Fourth paragraph outlines what is next—faster dry-run previews before destructive steps ship to production sandboxes.
