---ci--- project: acdl phase: 21 milestone: v1.6 status: execute ---/ci--- Introduce platform-managed environments: a consumer does not provide an AWS account, VPC, subnet, S3 state bucket, or runner key. A named environment is a platform-owned bundle of account + network + state backend + IAM role (surfaced via ABAC), selected by name in the contract. Scaffold: - core/environments/dev.json (sample dev env definition) - core/environments/README.md (how envs are used + how to add one) - core/environment_check.py (reads a contract's environment field, looks up core/environments/<name>.json, prints a friendly onboarding prompt when none exists, exits non-zero) - scripts/run_platform.sh: Step 0 calls environment_check.py before contract validation; a missing env halts the pipeline with the onboarding prompt - tests/test_environment_check.py: 12 tests (dev bound, missing env -> onboarding prompt, onboarding message lists provisions, contract paths, wire-in, check-only still passes) Tests: 166 pass (154 + 12 new).

"""Environment onboarding check.
|
|
|
|
Reads a contract's `environment` field and looks up the matching
|
|
`core/environments/<name>.json`. If no matching file exists, prints a
|
|
friendly onboarding prompt and exits non-zero, halting the pipeline before
|
|
any work is done.

Usage:

python3 core/environment_check.py <contract.yaml>
