core/env.py dual-read helper (D-108); 21 ACDL_*→NOVA_* env vars migrated across core/scripts/adapters/tests/workflows + .env/.env.secrets (key rename, values stay). G-106 binding: run_platform.sh:288-289 + regression_verify.py:309-312 dual-read (NOVA first, ACDL fallback). G-108 binding: Gitea NOVA_* secrets created via API + workflow secrets: refs updated (deploy.yml + modules-lifecycle.yml, .gitea + .github). acdl_tagging.py→nova_tagging.py (D-109 warn mode, nova:* enforced). .acdl/→.nova/ consumer path (resolver + deploy workflow + schema + tests + docs). Test fixtures updated; pytest + run_ci.sh PASS. ---ci--- project: acdl phase: 2 milestone: v1.15 status: execute ---/ci---

# Versioning
|
|
|
|
Nova uses two versioning schemes: one for modules, one for the deploy
|
|
pipeline. Both matter to a consumer.
|
|
|
|
## Module versioning
|
|
|
|
Primitives and modules use **semver** with three triggers:
|
|
|
|
- **interface → MAJOR** — a breaking change to the module's inputs/outputs.
|
|
- **behavior → MINOR** — a backward-compatible behavior change.
|
|
- **lifecycle → PATCH** — a fix or internal change.
|
|
|
|
A MAJOR bump requires a **new registry entry** (immutable publication); the
|
|
old entry enters a **12-month deprecation window**. A module pins its
|
|
primitives by `name@semver`; the resolver picks the highest compatible.
|
|
|
|
Module versions are tracked in
|
|
[`registry.json`](https://github.com/nova/nova/blob/main/modules/registry.json).
|
|
|
|
## Deploy-pipeline versioning (the CI workflow `uses:` tag)
|
|
|
|
The central deploy pipeline is referenced by a **floating MAJOR + MINOR
|
|
tag** in a consumer's CI workflow definition:
|
|
|
|
```yaml
|
|
jobs:
|
|
deploy:
|
|
uses: acdl/.github/workflows/deploy.yml@v1.13
|
|
with:
|
|
contract: .nova/contract.yml
|
|
```
|
|
|
|
The version pin lives in the CI workflow reference (not in the contract
|
|
itself — the contract no longer carries a `uses:` field). The CI workflow
|
|
`uses:` tag is the only immutability lever a consumer has.
|
|
|
|
**Unversioned references are discouraged.** Do not use `@main` or a bare
|
|
`acdl/.github/workflows/deploy.yml` — `main` is constantly updated and can
|
|
cause unexpected failures. Pinning to a MAJOR+MINOR tag means:
|
|
|
|
- **Immutability** — the pipeline behavior you tested is the behavior you
|
|
get. Patch fixes flow within the tag; breaking changes land under the
|
|
next MINOR tag (`@v1.5`), which you opt into explicitly.
|
|
- **Resilience** — your deployment does not break because an unrelated
|
|
change landed on `main`.
|
|
- **Reproducibility** — your setup is stable. You upgrade on your schedule
|
|
by bumping the tag.
|
|
|
|
## When a new tag is released
|
|
|
|
When a new MINOR tag is released (e.g. `@v1.5`), review its changelog and
|
|
bump your `uses:` reference when ready. The old tag continues to receive
|
|
patch fixes until the next MINOR tag.
|
|
|
|
## Production-bound references
|
|
|
|
For production-bound workflows, the platform resolves the current tag to its
|
|
SHA (tag for dev/qa, SHA for prod). This prevents a silent patch from
|
|
changing a production deployment. The platform provides a CLI command for
|
|
the tag → SHA resolution. |
