+# backup-verify — weekly "a backup is not trusted until restored" (CONTRACT_004
+# §4.6, T14 state-dependent half). Produces a fresh bundle and asserts it restores
+# from the OFFSITE copy into scratch resources (NON-DESTRUCTIVE — restore.sh never
+# touches the live platform). Runs on the foundation's own runner in foundation-ci.
+#
+# It reuses the operator scripts UNCHANGED (backup/backup.sh + restore.sh), which
+# read everything from `pulumi config get` (vm coords, vault root token, offsite +
+# age creds — all in the committed, passphrase-encrypted Pulumi.foundation.yaml) and
+# orchestrate the heavy lifting on the VM over SSH (ADR-007). Two CI-specific needs:
+#   1. the operator SSH key (SSH_PRIVATE_KEY secret → /tmp/op_key) to reach the VM;
+#   2. real Pulumi STATE imported into a file backend, because backup.sh embeds a
+#      `pulumi stack export` (pulumi-state.json, CONTRACT_004 §4.2) in the bundle —
+#      a bare `stack init` would ship an EMPTY deployment. State is pulled from the
+#      object run.sh publishes (state-publish.sh), same as pulumi-preview.
+#
+# Schedule only (+ manual dispatch): never on push — it creates real backup bundles.

+# pulumi-preview — read-only infra drift / PR check (T14, state-dependent half).
+#
+# Runs on the foundation's OWN runner in the baked foundation-ci image. Unlike
+# ci.yml (self-contained), this needs Pulumi STATE, which bootstrap/state/ is
+# gitignored from. It pulls the latest `pulumi stack export` that run.sh publishes
+# to rfs/foundation-ci-state/foundation-stack.json on every `up` (state-publish.sh),
+# imports it into a throwaway file backend, and previews. CONFIG + encrypted
+# secrets come from the committed Pulumi.foundation.yaml (the passphrase decrypts).
+#
+# READ-ONLY: `pulumi preview` only — NEVER `up`. It dials the VM docker over SSH
+# the same way the operator does (ADR-007), so the operator key is materialized
+# from the SSH_PRIVATE_KEY secret. A diff is informational (expected on infra PRs),
+# so the job does NOT fail on changes — it fails only if the program/preview errors.
+#
+# Secrets (repo-scoped, set via the admin API): PULUMI_CONFIG_PASSPHRASE,
+# SSH_PRIVATE_KEY (operator ed25519), RUSTFS_ACCESS_KEY/RUSTFS_SECRET_KEY (scoped
