Observers
Observers concepts mapped to actual Forge source packages.
Observers let applications receive execution events without replacing the model or tool executor. Keep handlers bounded and avoid silently turning observer failures into successful business operations. Use the actual Rust observer/event types and compare the language-specific exported surface before porting an implementation.
Implementation references
The references below are the Rust implementation. They include manifest versions, features, source hashes, and declarations.
Other languages
Use the language-specific package catalog for TypeScript, Python, Go, Swift and Kotlin. Similar responsibilities do not imply the same types, defaults, targets or deployed capabilities.
Validation
Read the exact package boundary and selected feature conditions. Run the relevant library tests and the applicable conformance fixtures before making a release claim. Source documentation and generated inventories do not replace runtime verification.
