+# GitHub Workflows — Nova Platform CI/CD Catalog
+
+This directory contains the 7 GitHub Actions workflows for the Nova
+platform. 3 are byte-identical Gitea mirrors (generated from
+`workflows-src/` by `scripts/sync_workflows.py`, P8/REQ-172); 4 are
+GitHub-only (Gitea act_runner feature gaps).
+
+## Shared workflows (byte-identical Gitea + GitHub)
+
+These 3 are generated from `workflows-src/<name>` by
+`scripts/sync_workflows.py`; the `.gitea/workflows/<name>` mirror is kept
+byte-identical. Run `python3 scripts/sync_workflows.py --check` to verify
+no drift.
+
+| Workflow | Trigger | Inputs | Required Secrets | Purpose |
+|----------|---------|--------|------------------|---------|
+| `ci.yml` | `pull_request: [main]` | — | — | Lint + test + check-only (runs on every PR) |
+| `deploy.yml` | `workflow_call` (reusable) + `push: [main]` | `contract` (string, required), `mode` (string, default `deploy`), `changeRequestId` (string), `environment` (string) | `NOVA_AWS_ACCESS_KEY_ID`, `NOVA_AWS_SECRET_ACCESS_KEY`, `NOVA_AWS_DEFAULT_REGION`, `NOVA_KMS_KEY_ID`, `NOVA_LAMBDA_URL` | Reusable deploy workflow (invoked by consumer repos via `uses: acdl/.github/workflows/deploy.yml@v1.15`) |

+
+## GitHub-only workflows (no Gitea mirror)
+
+These 4 have no Gitea counterpart (Gitea act_runner lacks the features
+they require — reusable workflows, matrix `needs`, release API). See
+`.gitea/workflows/README.md` for the limitation rationale.
+
+| Workflow | Trigger | Inputs | Required Secrets | Purpose |

+## Reusable deploy workflow (`deploy.yml`)
+
+Consumer repos invoke the deploy workflow via a versioned tag:

+```yaml

+    with:

+
+The workflow checks out the consumer repo + the Nova platform repo, runs
+`scripts/run_platform.sh`, and posts deploy outputs as a PR comment +
+to SSM Parameter Store.

+# Nova Onboarding — No-Humans Request Path (v1.16, REQ-182..184)
+
+The v1.16 milestone implements the **request path** of the no-humans
+onboarding flow (D-113). A consumer can submit an onboarding request
+without contacting the platform team; the platform generates an
+environment binding + (in a future milestone) provisions the AWS resources.
+
+## The 3-step request path
+
+### Step 1 — Submit an onboarding request (P18, REQ-182)
+
+A consumer submits an onboarding request to the Nova platform Lambda:
+
+```bash
+# Via the Lambda Function URL (IAM auth):
+curl -X POST "$NOVA_LAMBDA_URL" \
+  -H "Content-Type: application/json" \
+  -d '{
+    "action": "onboard_consumer",
+    "consumerRepo": "acdl/my-app",
+    "requestedEnvironment": "dev",
+    "ownerId": "team-x",
+    "billingTag": "cost-center-x"
+  }'
+```
+
+The Lambda validates the payload against
+[`schemas/onboarding.schema.json`](../schemas/onboarding.schema.json),
+then writes a `pending` row to the `nova-contracts` DynamoDB table
+(D-119). No AWS resources are created by this action (D-113).
+
+### Step 2 — Generate an environment binding (P19, REQ-183)
+
+The platform (or the consumer locally) generates an environment binding
+file from the request:
+
+```bash
+python3 core/onboarding.py --request '{
+  "consumerRepo": "acdl/my-app",
+  "requestedEnvironment": "qa",
+  "ownerId": "team-x",
+  "billingTag": "cost-center-x"
+}' --out core/environments/qa.json
+```
+
+This produces a `<env>.json` from the `dev.json` template, filling in
+the `ownerId` + `billingTag` + a description. The `account_id` is a
+placeholder (`000000000000`) for the platform team to fill with the real
+account. The generated file validates against
+[`schemas/environment.schema.json`](../schemas/environment.schema.json).
+
+### Step 3 — Cross-account role + ABAC tag grant (P20, REQ-184)
+
+The platform authors the consumer deploy-role + `nova:owner` ABAC tag
+grant via Terraform:
+
+```bash
+cd terraform/onboarding
+terraform init -backend=false
+terraform validate
+NOVA_AWS_ACCOUNT_ID=123456789012 terraform plan \
+  -var consumer_repo=acdl/my-app \
+  -var owner_id=team-x
+```
+
+**Offline-proven only (D-114):** `terraform validate` + `terraform plan`
+pass; **no live apply** in v1.16. The live apply (creating the real
+cross-account role + OIDC trust) is deferred to a future feature
+milestone (D-113).
+
+## What is NOT automated (deferred)
+
+- **Real AWS account/network/state provisioning** — the request path
+  generates a binding file with a placeholder `account_id`; the actual
+  AWS account creation + VPC + state backend is a future feature (D-113).
+- **Live cross-account role apply** — the Terraform is offline-proven
+  only (D-114); live apply is deferred.
+- **OIDC trust policy** — the onboarding Terraform uses a placeholder
+  OIDC provider; real OIDC federation is blocked on
+  go-gitea/gitea#36988 (carries forward from v1.1).

+# terraform/onboarding/ — Consumer deploy-role + ABAC tag grant (P20, REQ-184)
+
+Offline-proven Terraform for the cross-account consumer deploy-role +
+`nova:owner` ABAC tag grant. This is the "role grant" half of the
+no-humans onboarding flow (D-113); the "request" half is P18 (Lambda
+action) + P19 (env-file autogen).
+
+## Scope (D-114)
+
+This Terraform is **offline-proven only** in v1.16:
+- `terraform validate` passes.
+- `terraform plan` (with `NOVA_AWS_ACCOUNT_ID` set) produces the expected
+  role + policy.
+- **No live apply** — `NOVA_LIFECYCLE_MODE=plan` default. Live apply is
+  deferred to a future feature milestone (D-113/D-114).
+
+## Variables
+
+| Variable | Description | Default |
+|----------|-------------|---------|
+| `consumer_repo` | The consumer repository (org/repo) | `acdl/consumer-a` |
+| `owner_id` | The owning team (for `nova:owner` tag) | `team-a` |
+| `account_id` | The consumer's AWS account ID | `000000000000` |
+| `region` | AWS region | `us-east-1` |
+
+## Resources
+
+- `aws_iam_role.consumer_deploy` — the consumer's deploy role with a
+  trust policy (assumed by the consumer's CI runner).
+- `aws_iam_role_policy.consumer_invoke` — inline policy granting
+  `lambda:InvokeFunctionUrl` on the platform Lambda, scoped via
+  `aws:PrincipalTag/nova:owner == var.owner_id` (ABAC).
+- `aws_iam_tag.owner` — tags the role with `nova:owner` + `nova:contract`.
+
+## Usage (offline)
+
+```bash
+cd terraform/onboarding
+terraform init -backend=false
+terraform validate
+NOVA_AWS_ACCOUNT_ID=123456789012 terraform plan -var consumer_repo=acdl/my-app -var owner_id=team-x
