isDirty is not really a database functionality. Most of the time isDirty() is there to inform you that a child or parent object did not any data.
So isDirty can tell you if a join was successful or not.

Thanks Teddy - definitely a useful introduction.
One bit was particularly relevant:
"When Record objects are validated the validation cascades to dirty
children. So if you have a user who hasMany addresses, when you call
user.validate() it will validate any addresses that are dirty."
That makes complete sense and has given me a big hint in how to tackle
a problem that I was thinking of using a class table inheritance
pattern on, but hadn't worked out how.
But that also makes me think that what I am seeing now is a bug - the
Agency Record is NOT dirty.
