# CI Pipeline

The CI runs on every push to `main` and every pull request. It uses smart scoping to skip expensive jobs when only unrelated areas changed.

## Job Overview

| Job                      | Purpose                                                                                  | When it runs                        |
| ------------------------ | ---------------------------------------------------------------------------------------- | ----------------------------------- |
| `preflight`              | Detect docs-only changes, changed scopes, changed extensions, and build the CI manifest  | Always on non-draft pushes and PRs  |
| `security-fast`          | Private key detection, workflow audit via `zizmor`, production dependency audit          | Always on non-draft pushes and PRs  |
| `build-artifacts`        | Build `dist/` and the Control UI once, upload reusable artifacts for downstream jobs     | Node-relevant changes               |
| `checks-fast-core`       | Fast Linux correctness lanes such as bundled/plugin-contract/protocol checks             | Node-relevant changes               |
| `checks-fast-extensions` | Aggregate the extension shard lanes after `checks-fast-extensions-shard` completes       | Node-relevant changes               |
| `extension-fast`         | Focused tests for only the changed bundled plugins                                       | When extension changes are detected |
| `check`                  | Main local gate in CI: `pnpm check` plus `pnpm build:strict-smoke`                       | Node-relevant changes               |
| `check-additional`       | Architecture, boundary, import-cycle guards plus the gateway watch regression harness    | Node-relevant changes               |
| `build-smoke`            | Built-CLI smoke tests and startup-memory smoke                                           | Node-relevant changes               |
| `checks`                 | Heavier Linux Node lanes: full tests, channel tests, and push-only Node 22 compatibility | Node-relevant changes               |
| `check-docs`             | Docs formatting, lint, and broken-link checks                                            | Docs changed                        |
| `skills-python`          | Ruff + pytest for Python-backed skills                                                   | Python-skill-relevant changes       |
| `checks-windows`         | Windows-specific test lanes                                                              | Windows-relevant changes            |
| `macos-node`             | macOS TypeScript test lane using the shared built artifacts                              | macOS-relevant changes              |
| `macos-swift`            | Swift lint, build, and tests for the macOS app                                           | macOS-relevant changes              |
| `android`                | Android build and test matrix                                                            | Android-relevant changes            |

## Fail-Fast Order

Jobs are ordered so cheap checks fail before expensive ones run:

1. `preflight` decides which lanes exist at all. The `docs-scope` and `changed-scope` logic are steps inside this job, not standalone jobs.
2. `security-fast`, `check`, `check-additional`, `check-docs`, and `skills-python` fail quickly without waiting on the heavier artifact and platform matrix jobs.
3. `build-artifacts` overlaps with the fast Linux lanes so downstream consumers can start as soon as the shared build is ready.
4. Heavier platform and runtime lanes fan out after that: `checks-fast-core`, `checks-fast-extensions`, `extension-fast`, `checks`, `checks-windows`, `macos-node`, `macos-swift`, and `android`.

Scope logic lives in `scripts/ci-changed-scope.mjs` and is covered by unit tests in `src/scripts/ci-changed-scope.test.ts`.
The separate `install-smoke` workflow reuses the same scope script through its own `preflight` job. It computes `run_install_smoke` from the narrower changed-smoke signal, so Docker/install smoke only runs for install, packaging, and container-relevant changes.

On pushes, the `checks` matrix adds the push-only `compat-node22` lane. On pull requests, that lane is skipped and the matrix stays focused on the normal test/channel lanes.
