🇪🇸 Espejo legible del banco de preguntas; la fuente canónica es data/quizzes/phase-38-mlops.yaml.

q-38-01 — Non-negotiable property of a deploy flow

  • A canary deployment is configured
  • A rollback path exists (previous artifact preserved + traffic flip ready) ← correct
  • A feature flag has been created
  • A blue/green pair is up in both regions

q-38-02 — Blocking checks on a PR touching src/minitutor/

  • just lint ← correct
  • just typecheck ← correct
  • just test ← correct
  • just bench --quick

q-38-03 — What does the eval-gate threshold defend against?

Free response. Acceptable answers contain regression.

A quality regression — a release whose aggregate eval score drops more than the threshold.

q-38-04 — Rollback latency

  • ~1 second
  • ~30 seconds (bake-period verification dominates) ← correct
  • ~10 minutes (rebuild)
  • ~1 hour

See theory/06-build-deploy-rollback-and-ci-matrix.md and the /break for the cost of missing rollback.
