model: branch-based deployments
description: >-
  Chalk has no test-card/magic-value sandbox (it is a data platform, not a payments API).
  Its testing surface is isolated branch deployments: changes to features and resolvers can
  be deployed to a named branch and queried in isolation before promotion to the main
  environment, so pipelines can be validated against real data sources without affecting
  production.
mechanisms:
- name: branches
  detail: "Create an isolated deployment with `chalk apply --branch <name>` / `chalk branch`; route queries with the branch / branch_id parameter."
- name: environments
  detail: "Requests carry an `environment` parameter selecting the deployment context (e.g. staging vs production)."
- name: preview_deploys
  detail: "Branch deployments act as previews for feature-pipeline changes prior to promotion."
note: No published static test credentials or fixture values; never fabricated.
