 Both `@airiscode/core` and `@airiscode/cli` use plain `tsc` for build (not tsup) — if a
 type error shows up, `pnpm --filter <pkg> typecheck` reproduces it fastest.

+### Runtime — host-native by default
+
+Per the org runtime policy (SSoT: `~/.claude/rules/runtime-workflow.md`), development on
+the dev machine (Mac) is **host-native**: run build / test / lint / typecheck directly
+with the native toolchain (`pnpm` + Turbo + Vitest) — no container required. The old
+"docker-first" mandate is retired.
+
+A Docker dev shell (`Dockerfile` at root + `compose.yaml`, generated by `airis workspace
+gen`) is **optional** — use it only for (1) local stateful infra or (2) parity checks
+against the deploy target. `airis workspace gen` is opt-in config generation, not a
+required step.
+
+Note: this repo is a **fork of upstream Qwen Code** (`origin` = `agiletec-inc/airiscode`).
+Keep the generated surface minimal and don't push `airis`-generated artifacts
+(`compose.yaml`, etc.) upstream where they'd pollute a future re-sync.
