+# 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`) |
+| `modules-lifecycle.yml` | `pull_request: [main]` + `workflow_dispatch` | `lifecycle_mode` (string, default `plan` — `plan` or `full`) | `NOVA_AWS_ACCESS_KEY_ID`, `NOVA_AWS_SECRET_ACCESS_KEY`, `NOVA_AWS_DEFAULT_REGION`, `NOVA_AWS_ACCOUNT_ID` | L1 + L2 module lifecycle pipeline (plan-only default; full apply/modify/destroy on override) |
+
+## 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 |
+|----------|---------|--------|------------------|---------|
+| `platform-test.yml` | `pull_request: [main]` | — | — | Lint + unit + integration + schema-validation (replaces `ci.yml` for PRs) |
+| `primitives-plan.yml` | `pull_request: [main]` | — | `NOVA_AWS_*` | Plan-only for all L1 primitives (matrix) |
+| `patterns-plan.yml` | `pull_request: [main]` | — | `NOVA_AWS_*` | Plan-only for all L2 modules (matrix) |
+| `release.yml` | `push: [main]` | — | `NOVA_GITEA_TOKEN` (for Gitea release API) | Semver tag + MAJOR.MINOR/MAJOR floating-tag maintenance + release creation on merge to main |
+
+## Reusable deploy workflow (`deploy.yml`)
+
+Consumer repos invoke the deploy workflow via a versioned tag:
+
+```yaml
+jobs:
+  deploy:
+    uses: acdl/.github/workflows/deploy.yml@v1.15
+    with:
+      contract: .nova/contract.yml
+      environment: dev
+    secrets: inherit
+```
+
+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.

+
+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

+This is the "request path" half of the no-humans onboarding flow (D-113).

+generating the binding file + emitting a git patch / PR-branch instruction.
