Looks good!

All adaptations are checked at connection time to ensure type safety, but applied at runtime during pipeline execution.

When multiple connections are possible, strict type matching is prioritized over implicit conversion.
This preserves backward compatibility with earlier versions of Haystack, where flexible type connections were not supported.

[Google.Contractions] Feel free to use 'weren't' instead of 'were not'.

- Type conversions not covered by implicit adaptation
- Explicit control over formatting or ordering

Smart connections reduce the need for glue components, but they do not remove them entirely.
