# Glue programs

Forty small, deterministic workflows with behavioral tests. Run them with:

```sh
vibes test --profile low corpus/glue
```

The CLI integration suite runs the same command during `./scripts/cargo test
--offline --workspace`. Each directory is an independent module root. Tests
require the program inside their test function, since test files contain only
declarations. Capability operations are supplied as typed blocks or script
doubles; no network access or host credentials are needed.

[The evaluation report](../../docs/authoring-evaluation.md) explains the first
attempts, repairs, limitations and language proposals. `evaluation.jsonl` stores
all 40 original drafts and subsequent attempts, plus separately seeded spelling
exercises. Those drafts are data, so the normal test runner never discovers and
executes the intentionally failing versions. The replay script verifies their
source hashes before writing them to a fresh output directory.
