Genericize forge-detection code: gitea→forge/generic_forge, GITEA_ACTOR→FORGE_ACTOR. Drop .gitea byte-identity test assertions (keep GitHub-side + contract conformance). Add test_no_forge_mentions.py guard test (REQ-230). Delete completed migration docs (NOVA_MIGRATION.md, NOVA_AWS_MIGRATION.md). Move NO_HUMANS_THESIS.md to .ciagent/ (internal artifact). Strip ciagent-internal provenance from synced docs (REQ-/D-/P-/CAP- IDs, milestone headers, .ciagent/PROJECT.md citations). Trim README.md (reusable deploy section, local key rotation paragraph). Fix version-tag drift (@v1.13→@v1.19, acdl/→nova/). ---ci--- project: acdl phase: 1 milestone: v1.20 status: execute requirements: [REQ-230, REQ-231, REQ-232] ---/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: nova/.github/workflows/deploy.yml@v1.19
|
|
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
|
|
`nova/.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. |
