Project Evolution

Real protocols rarely remain in one file or one version. This example combines two workflows:

• vexilc build resolves imports and emits a Rust module tree;
• vexilc compat distinguishes a compatible declaration addition from a breaking field-type change.

Run the complete path from the repository root:

python scripts/examples.py check project-evolution

The command expects the compatible comparison to succeed and the breaking comparison to exit with status 1. A failure path is part of the example rather than something the guide asks you to imagine.

Read the guided example README for the schema layout and expected reports.
