Hands-on fixtures

Each fixture supports one numbered exercise in the catalog. Use scripts/prepare-hands-on.js from the repository root to copy only the selected fixture to an unused directory outside the curriculum.

Behavior categories

• Runnable baselines: interface, library, cart, inventory and SDK offline tests.
• Intentionally incomplete: the issue equality boundary, greenfield store, brownfield metadata and modernization storage adapter.
• Instructor references: reference/ directories; the preparation script omits them so the learner must implement the exercise.
• Historical console illustrations: example output and architecture notes are not executed evidence or coverage reports.

Verification

The root npm test checks source links, metadata, diagrams and selected deterministic Node fixtures. Python and .NET tests are executed separately using the commands in the audit/reference guidance. No live model, provider or cloud operation is triggered by the root test.

Use the resource-limited setup before commands. Retain the license when redistributing a copy.
