Runnable harness compositions. **Examples are not workspaces:** private package stubs are not built. App bins load each `cordis.yml` through `tsx`; package names resolve through root `tsconfig.json` paths, not `node_modules`.
Keep wiring, demo fixtures, and e2e/snapshot scenarios here. Move reusable logic into `packages/`, with coverage and a README. App bins own bootstrapping; examples have no `start.ts`.
- **Keyless:** boot the real `cordis.yml` through the Loader, drive it, and assert output and clean exit. Catches Loader/export-shape failures hand-mounted tests miss ([postmortem](../docs/postmortem/0001-acp-default-export-drops-inject.md)).
- **With-key:** send a live-model prompt and verify external state, not the model's claim. Self-skip without `DEEPSEEK_API_KEY`; see [testing.md](../docs/testing.md).
In `cordis.yml`, comment only non-obvious wiring, load-order consequences, replay, security boundaries, and configuration scope. Do not narrate visible entries; use [dsh-prose-standard](../.agents/skills/dsh-prose-standard/SKILL.md) for required coverage and editorial judgment.
