Private/Exceptions/AvmExceptions.ps1

#Requires -Version 7.4

# Typed exception classes per spec section 14. Loaded by Avm.Authoring.psm1
# alongside every other Private/ file via dot-sourcing. PowerShell parses
# 'class' blocks at dot-source time so the type is visible to subsequent
# Private/ and Public/ files via the type accelerator and via
# '[Avm.Errors.AvmToolException]::new(...)'.
#
# The base class derives from System.Exception so that our own throws look the
# same as framework exceptions to PowerShell's exception machinery and to
# Pester's -ExceptionType assertions.
