Dependencies
| Library | Version | Measured there | Projects |
|---|---|---|---|
| prelude-ls | 1.2.1 | contract passed | 6 project-days |
| type-check | 0.4.0 | contract passed | 6 project-days |
The measured column is about each dependency's own release, not about the pair. A resolver placing two releases side by side is not evidence that they work together.
