 Tier 1 runs on every `bun run test`. Tiers 2+3 are gated behind `EVALS=1`. The idea: catch 95% of issues for free, use LLMs only for judgment calls and integration testing.

-Anything that needs Aside itself — `test/skill-e2e-aside.test.ts`, the Aside cases in the qa and design-review E2E files, the live round-trip in `test/aside-render.test.ts` — runs only on a Mac with the Aside app open and self-skips elsewhere (`asideAvailable()` in `test/helpers/aside-available.ts`; `GSTACK_SKIP_ASIDE=1` forces the skip). The render gates are engine-agnostic: make-pdf's `*-gate.test.ts` and `test/skill-e2e-diagram.test.ts` run through whichever engine resolves (`browserAvailable()` in `make-pdf/test/e2e/browser-available.ts` = `asideAvailable() || resolveBrowseBin() !== null`) and skip only when neither exists, so Linux CI builds the browse binary with `bun run build:gates` and runs them live. The fallback engine's own tests (`browse/test/`, the `$B`-driven E2E cases) run on every platform as before: Linux CI proves the fallback path live and the Aside contract statically.
