## What
Makes `yarn twenty docker:start` version-selectable. Same core feature
as #21686 — but here scaffolded apps default to `latest` (pinning is
**opt-in**) rather than being pinned to the scaffolder's version.
> Alternative to #21686. Pick one; the difference is only the scaffolded
default.
Two layers of resolution:
1. **Explicit flag** — `yarn twenty docker:start [version]`, mirroring
the existing `docker:upgrade [version]`.
2. **App-pinned default** — when no version is passed, `docker:start`
reads `twenty.serverVersion` from the app's `package.json`, falling back
to `latest`.
Generated apps ship `twenty.serverVersion: "latest"`, so default
behavior is unchanged. To make the local server reproducible as code,
set a version:
```json filename="package.json"
{
"twenty": {
"serverVersion": "2.2.0"
}
}
```
## Changes
- `twenty-sdk`: new `getAppServerVersion()` util reads
`twenty.serverVersion` from the cwd's `package.json`; `serverStart`
gains a `version` option and resolves `option → app pin → latest`,
building the image via `getImageForVersion()`; `docker:start [version]`
(and the deprecated `server start [version]` alias) wired up.
- `create-twenty-app`: template `package.json` ships
`twenty.serverVersion: "latest"`. (`create-app` and the scaffolder are
otherwise untouched.)
- Docs: `local-server.mdx` documents version selection and the opt-in
pin.
## Behavior notes
- Default with no pin and no flag is `latest` — same as today.
- Version only matters when **creating** a fresh container — an existing
container keeps its image until `docker:upgrade` / `docker:reset`.
## Testing
- New unit tests for `getAppServerVersion` (5 cases).
- Extended the `app-template` scaffolding test to assert the `latest`
default.
- `twenty-sdk` cli vitest suite (273) and `create-twenty-app` jest suite
(9) pass; oxlint + oxfmt clean on changed files.
