Dev-Branch Deploy — Hermes & Maia

Test a Hermes or Maia stack change in a live lab region before merging to master, using the pipeline's parallel dev lane. One workflow, two stacks — parametrized by stack.

The problem this solves

Concourse pins a git branch: per resource at pipeline-definition time; you can't override it at trigger time. So normally you must merge to master to see a chart/secrets change run in a lab. The dev lane adds a second set of jobs pointed at <stack>-dev-branch, so you deploy and validate in a real lab region with no risk to master or production.

Stack parameters

Everything below is identical between stacks except these values.
