      # A deploy that leaves the function empty (#424) or broken must fail this
      # run, not wait for a user report. The script reads SMOKE-TEST-KEY from
      # Key Vault with the OIDC login above — the CI principal has Key Vault
      # Secrets User scoped to that one secret (infra/README.md §7) — submits a
      # keyed report, and waits for it to become a closed `smoke-test` issue.

      # SMOKE_SETTLE_SECONDS: right after a deploy the previous host instance can
      # still hold the ProcessSubmissions singleton lease, so the first tick may
      # run the build we just replaced (#431). Wait for the handover so the test
      # exercises the code this run deployed.
