name: Infra CD

# Path-filtered CDK deploy for /infra, per env, OIDC-only (no static keys).
#
#   push to dev  → CI (tsc+jest+synth) → deploy OpenSweDevStack   (AUTO, CI-green-gated)
#   push to main → CI                  → deploy OpenSweProdStack  (manual approval: env "prod")
#
# Why this is NOT the reusable cd-cdk.yaml: that workflow runs `cdk deploy --all`,
# which would deploy ALL THREE stacks (incl. the OTHER env + the shared IAM stack)
# from a single-env push — breaking the per-env dev/prod boundary. So we target one
# stack explicitly per env. (Infra CI still uses the reusable ci-typescript-cdk.)
#
# The shared IAM stack (open-swe-iam — owns BOTH envs' OIDC deploy roles) is
# intentionally NOT deployed here: it is a privileged, human-gated apply (T6), so a
# routine dev push can never alter prod's deploy role.
#
# OIDC subject alignment (must match the per-env trust in infra/lib/config.ts):
#   - deploy-dev declares NO `environment:` → token sub = repo:…:ref:refs/heads/dev,
#     which is exactly what githubdeploy-open-swe-infra-dev trusts.
#   - deploy-prod declares `environment: prod` → token sub = repo:…:environment:prod,
#     which githubdeploy-open-swe-infra-prod trusts AND which triggers the GitHub
#     Environment's required-reviewer (manual approval) gate.
#
# Prerequisites (post-T6, when the roles exist):
#   - repo variables AWS_DEPLOY_ROLE_INFRA_DEV / AWS_DEPLOY_ROLE_INFRA_PROD = the
#     githubdeploy-open-swe-infra-<env> role ARNs (open-swe-iam CfnOutputs).
#   - a GitHub Environment named "prod" with Adam as a required reviewer.
