- ppg/packer-hetzner: packer-plugin-hcloud refresh + seed templates, 12-combo design (7 active x86 rows until OL8/10 seeds and CAX stock), label-selector lineage chaining requiring source=factory + smoke=passed - fresh-boot smoke via shared smoke-run.sh: sentinel pair gates candidate deletion to genuine provisioner failures, smoke=passed labeled pre-promote - promote.sh with fail-closed role/env guard, prune.sh keep-4 retention with a two-tier stale sweep, janitor with namespaced selectors and honest failure semantics - GHA workflows: tokenless PR check, bake matrix, weekly cron + self-prune, 6h-apply janitor cron with Slack alerts, environment-scoped token jobs, setup-hcloud composite action, prod-serialized concurrency - OL base bootstrap (rescue-mode qcow2 upload, auto raw+xz conversion, EL10-safe cloud-init check) - molecule consumer vars (delegated driver, fail-closed selector) and the ppg-hetzner-poc pilot job (param validation, scoped credentials, per-workspace pinned collections with the hcloud datacenter guard)

Compare
- smoke-run.sh: fail-closed identity guard (promote.sh pattern) before the boot and again before the candidate delete, so a wrong or relabeled snapshot ID is never booted or deleted - refresh/smoke templates: ssh_keys_labels on the packer temp keys; janitor sweeps the two new roles so keys from killed runs cannot leak forever - tests/: stubbed hcloud+packer suites for both behaviors, run by check.sh
- Bake, prune, and janitor jobs assume a master-pinned GitHub-OIDC AWS role and read the Hetzner token from the /ppg/hcloud-factory-token SSM parameter, so no Hetzner credential lives in GitHub and a branch-ref dispatch fails at AssumeRole - Role + parameter are Terraform in percona-cd-platform (iam-gha-ppg-hcloud-factory.tf) - README token section updated; comment trims
- Tool-setup actions run before authentication; AWS credentials and the Hetzner token never enter the job env (step outputs, wired explicitly into each consuming step) - Janitor Slack alert moves to a credential-free job fed by sweep outputs - Fetch step rejects the SSM placeholder, role sessions capped at 900s, checkouts set persist-credentials: false - Bake gate is an explicit event allowlist, mutable role-ARN override dropped
