- Focus on CLI usage in CI environments.
- Show GitLab CI, GitHub CI and Gitea CI examples.

## Architecture

szci is a thin orchestrator that delegates heavy lifting to specialized tools:
- **Docker**: Delegates all operations to `@git.zone/tsdocker` via `npx`
- **NPM**: Thin wrapper around `pnpm` with .npmrc generation from `SZCI_TOKEN_NPM*` env vars
- **Node.js**: NVM-based version management (stable=22, lts=20, legacy=18)
- **SSH**: Deploys SSH keys from `SZCI_SSHKEY_*` env vars
- **Git**: GitHub mirroring via `SZCI_GIT_GITHUBTOKEN`
- **Cloudly**: Integration with serve.zone infrastructure

## Docker Env Var Bridging

szci bridges its own env var format to tsdocker's format before delegation:
- `SZCI_LOGIN_DOCKER*` -> `DOCKER_REGISTRY_N` (pipe-delimited: `url|user|pass`)
- GitLab CI: `CI_JOB_TOKEN` -> `DOCKER_REGISTRY_0` for `registry.gitlab.com`

## Deno Migration Status

The project has been fully migrated from Node.js to Deno runtime.

### Environment Variables

All environment variables have been rebranded from NPMCI_* to SZCI_*:

| Old Name | New Name |
|----------|----------|
| `NPMCI_COMPUTED_REPOURL` | `SZCI_COMPUTED_REPOURL` |
| `NPMCI_URL_CLOUDLY` | `SZCI_URL_CLOUDLY` |
| `NPMCI_GIT_GITHUBTOKEN` | `SZCI_GIT_GITHUBTOKEN` |
| `NPMCI_GIT_GITHUBGROUP` | `SZCI_GIT_GITHUBGROUP` |
| `NPMCI_GIT_GITHUB` | `SZCI_GIT_GITHUB` |
| `NPMCI_SSHKEY_*` | `SZCI_SSHKEY_*` |
| `NPMCI_LOGIN_DOCKER*` | `SZCI_LOGIN_DOCKER*` |
| `NPMCI_TOKEN_NPM*` | `SZCI_TOKEN_NPM*` |
| `NPMTS_TEST` | `SZCI_TEST` |
| `DEBUG_NPMCI` | `DEBUG_SZCI` |

### Runtime

- Uses Deno APIs (`Deno.env`, `Deno.cwd`, `Deno.exit`)
- Logger runtime set to 'deno'
- Dynamic imports use `.ts` extensions

## Removed Modules (v7+)

The following were removed as dead/obsolete code:
- `mod_trigger` - Deprecated GitLab API v3
- `mod_precheck` - GitLab-specific runner tag validation
- `manager.cloudron` - Niche Cloudron deployment
- `mod_command` - Trivial bash wrapper
- `mod_clean` - Trivial config cleanup
- Docker manager internals (Dockerfile, DockerRegistry, RegistryStorage classes) - replaced by tsdocker delegation
