What’s New

v2.4.0 is an internal architecture and dependency-hygiene release. It introduces a new low-level package, cognesy/instructor-contracts, and uses it to break a circular dependency between cognesy/instructor-struct and cognesy/instructor-dynamic. It also repairs a set of cross-package dependency declarations across the monorepo so that each package now declares exactly what it uses — which makes standalone (split-package) installs resolve correctly. There are no breaking changes to public APIs. Class names and namespaces are unchanged; the moved contracts keep their existing Cognesy\Instructor\… namespaces.

​
New package: cognesy/instructor-contracts

A new foundation package holds the small, dependency-light abstractions that several Instructor packages share — validation, transformation, and deserialization contracts plus their value objects. It depends only on cognesy/instructor-utils. Moved into the package (namespaces preserved, so no consumer code changes):
  • Cognesy\Instructor\Validation\ValidationResult, ValidationError
  • Cognesy\Instructor\Validation\Contracts\CanValidateSelf, CanValidateObject, CanValidateValue
  • Cognesy\Instructor\Transformation\Contracts\CanTransformSelf, CanTransformData
  • Cognesy\Instructor\Deserialization\Contracts\CanDeserializeClass, CanDeserializeSelf
The response-level orchestration classes (ResponseValidator, ResponseTransformer, and the *Response contracts) remain in cognesy/instructor-struct.

​
Broken dependency cycle: instructor-struct ↔ dynamic

Previously instructor-struct and dynamic depended on each other in code (each imported the other’s classes), which only worked because the monorepo autoloads every namespace. Both now depend on cognesy/instructor-contracts instead, removing the cycle:
  • dynamic no longer depends on instructor-struct.
  • dynamic deserializes nested concrete-class fields through the CanDeserializeClass contract, with a self-contained Symfony-based default implementation (SymfonyStructureDeserializer). instructor-struct’s SymfonyDeserializer is unchanged.

​
Cross-package dependency repairs

  • cognesy/logging naming. Six packages required a non-existent cognesy/instructor-logging; they now correctly require cognesy/logging. The Laravel package’s stale ^1.22 constraint on it is aligned to the current line.
  • Undeclared dependencies. Packages that used a sibling’s classes without declaring a Composer dependency on it now declare it, across 14 packages. This is invisible inside the monorepo but is required for correct standalone installs.
  • utils ↔ pipeline cycle. Cognesy\Utils\Str no longer depends on the pipeline package; its case-normalization is now dependency-free. The Pipeline-based variant is available as Cognesy\Pipeline\Extras\StringNormalizer.

​
Upgrade notes

No action required. All changes preserve existing class names, namespaces, and public behavior. Standalone consumers of individual cognesy/* packages benefit from the corrected dependency metadata automatically.
