# qol-arch-cicd: Cross-Platform CI/CD Infrastructure Contract
## Why this skill exists
The two sibling skills (`qol-arch-code`, `qol-arch-cross-platform`) try to prevent cross-platform breakage at edit time.
Static analysis can only see so much.
The **deterministic, can't-be-bypassed** catch is **building on every supported OS in CI, with warnings denied**.
The pre-monorepo history shows the cost when this slips: a qol-tray release once failed on its tag with green CI behind it because the release workflow had drifted from `ci.yml`, and sixteen `dead_code` errors reached `main` (`d797294`) because plugins declaring `platforms = ["linux", "macos"]` were only ever built on Linux.
The monorepo removed the multi-workflow drift class (one checkout, workspace deps), but platform coverage and warning parity still have to be enforced deliberately.
## Hard rules
### 1. Platform coverage derives from `plugin.toml` `platforms`
Release builds resolve their matrix from the plugin's declared `platforms` (`.github/scripts/plugin_matrix.py`), and CI's affected-crate planning reads the same field.
| Plugin platform | Runner |
|---|---|
| `linux` | `ubuntu-latest` |
| `macos` | `macos-latest` |
| `windows` | `windows-latest` |
No matrix-padding for OSes the plugin doesn't claim - macOS runners cost ~10x Linux, and red builds on platforms a plugin never meant to support train the reader to ignore red.
Never hardcode a runner list for plugin builds; if a plugin's platform set changes, `p
