 ## How to run
 
-### Prerequisites
+### Quick start (offline, no AWS required)
 
-> These prerequisites are for running the **platform repo** locally. A
-> consumer does not need any of these — see the
-> [Consumer guide](docs/consumer-guide.md) for the consumer happy path.
+The fastest way to verify the platform works — no AWS credentials, no
+bootstrap, no cost. See the [Consumer guide](docs/consumer-guide.md)
+for the consumer happy path (a consumer owns only a contract + app code).
 
-- A platform-managed environment (see [docs/environments/](docs/environments/)).
-  For local testing, `core/environments/dev.json` is provided as the sample.
-- AWS credentials for the dev environment (in `.env.secrets`, gitignored;
-  see [Credentials & zero-trust](#credentials--zero-trust)).
-- `terraform` (pin `1.9.*`), `checkov` (pin `>=3.2,<4`), `python3` + `boto3`
-  + `jsonschema`.

-### Run the platform pipeline end-to-end
+# 1. Run the test suite (all offline — uses moto for DynamoDB mocking)
+python3 -m pytest tests/ -v
+
+# 2. Run the platform in check-only mode (offline — contract -> resolver ->
+#    adapter -> structure validation). Uses the default sample contract
+#    (contracts/static-assets.yaml) + sample dev environment.
