+# Scaleway BYOC Integration Notes
+
+This package is still a preview provider path. When adding or changing
+Scaleway behavior, check the surfaces below so provider support does not stop
+at the deploy path.
+
+## Cross-Surface Checklist
+
+- Provider ID parsing, display names, protobuf mapping, and default regions.
+- Stack wizard provider choices and stack-name defaults.
+- Agent tool JSON schemas and tests that enumerate provider choices.
+- Compose fixups for managed services, models, ports, and config references.
+- CD setup, run, status, subscribe, logs, teardown, and state readback.
+- Docs pages, provider tables, managed LLM tables, and sample prerequisites.
+
+## Current Preview Constraints
+
+- CD runs on Scaleway Serverless Jobs and uses Object Storage for Pulumi state
+  and `project.pb` readback.
+- CD job definitions must be scoped per stack to avoid concurrent deployments
+  deleting or replacing each other's job definition.
+- Scaleway managed LLM support bypasses LiteLLM and injects OpenAI-compatible
+  environment variables that point at `https://api.scaleway.ai/v1/`.
+- Serverless Containers do not support host-mode ports; public HTTP services
+  must use ingress ports.
+- Portless workers use a temporary health shim in the Pulumi provider because
+  Serverless Containers require an HTTP listener.
+- Managed Redis currently requires `REDIS_PASSWORD` Defang config.
+- Managed PostgreSQL passwords must satisfy Scaleway's password policy.
