+"""Nova Onboarding — auto-generate an environment binding file (P19, REQ-183).
+
+Given a consumer onboarding request (validated against
+schemas/onboarding.schema.json), generate a ``<env>.json`` environment
+binding file from the dev template, filling in the consumer's ownerId +
+billingTag. The generated file is a starting point for the platform team
+(or a future automation) to bind to a real AWS account.
+
+This is the "request path" half of the no-humans onboarding flow (D-113).
+Real AWS account/network/state provisioning is a future feature milestone;
+this module removes the human handoff from the *request* step by
+generating the binding file + emitting a git patch / PR-branch instruction.
+
+Usage:
+    python3 core/onboarding.py <request.json> [--out <env.json>]
+    python3 core/onboarding.py --request '{"consumerRepo":"acdl/c","requestedEnvironment":"qa","ownerId":"team-a","billingTag":"cc-a"}'
