@copilot - According to this document, the OnExit fires before the transition commands. I would expect the OnExit to only fire when the Transition to the new state has occurred. In this example, it is after the TransitionCommand1 and TransitionCommand2. In the case of the OnExit yielding a command, then the change would only be in the order of the commands returned (which may still be important). However, OnExit is a data manipulation, then order is important.
If there was a ModifyData after the TransitionTo, I would also expect this to occur before the OnExit.
If the code does not behave this way, please add tests describing the behaviour I've described, and check for other tests that are currently describing different behaviour and amend them. Then implement the change.

The code already behaves correctly! The issue was only in the ARCHITECTURE.md documentation, which incorrectly stated that OnExit fires before transition commands.
Actual behavior (verified by tests):
- Transition commands (Execute)
- OnExit commands
- OnEntry commands
Fixed the documentation in commit 48d535f. The existing tests in StateMachineHierarchyTests.cs already verify this correct order:
Fire_UsesParentTransitionsverifies: Transition → Exit → Exit(parent) → EntryFire_DoesNotRunParentExitEntryBetweenChildrenverifies: Transition → Exit → Entry
- Correct execution order to match actual implementation - Guards and transition commands execute before OnExit - OnExit fires after transition commands (not before) - Actual order: Guards → Conditionals → Data → Transition → Exit → Entry - Example updated: [TransitionCmd1, TransitionCmd2, Exit, Entry] - Tests already verify correct behavior in StateMachineHierarchyTests Co-authored-by: leeoades <2321091+leeoades@users.noreply.github.com>

@copilot - I'm not sure how useful this code snippet is because it isn't something that the consumer of the library will encounter, right? If this is internal code then I'm not sure it's clear that it is.

Good point! Fixed in commit b23382c. Replaced internal code snippets with user-facing descriptions that explain what validation errors/warnings they'll see. The section now focuses on the experience of using the library rather than showing internal implementation details.

@copilot - How can such a Guard Evaluator be used? Please provide an example of usage.
There was a problem hiding this comment.
The IGuardEvaluator interface doesn't actually exist in the library - it was a misleading example. Removed in commit e8d454c. Guards are implemented as lambda functions passed to the .Guard() method (e.g., .Guard((state, data) => data.IsAuthorized)). The Extension Points section now only shows actual extensibility options.
