Read-only SDK support fixture

Run node --test --test-concurrency=1 app.test.mjs without packages or credentials. These tests exercise the application and handler with a fake SDK client; they do not evaluate a model.

Optional live execution uses the pinned dependency in package.json:

npm install
node live.mjs "What is the status of ORD-1?"

Inspect the tool allowlist and denial policy first. The runtime data directory is .copilot-runtime under this copy. Authentication may differ from the editor. Do not grant extra permissions automatically when a live operation is denied.

Source, reproducibility and contributions

Commands, source code, sample prompts, identifiers and exact data remain in their original form so the exercises stay reproducible.
