ad-hoc smoke testing of licensed endpoint metadata saves identified that the removed endpoints list was being overwritten to empty on subsequent saves after endpoints were removed.
As part of fixing this, AI was employed to write tests and identify any further issues. It found:

• the EFCore data store was not correctly removing the licensedendpointmetadata record when required (this was not originally tested due to the EFCore functionality not being complete yet, and later had only a minimal smoke test that didn't include removal)
• the inmemory data store (only used for testing) was mutating what should be the readonly backing store version of the licensedendpointdetails object

Additional tests were added to cover all the above cases.
None of this functionality was yet available for general use, so no customers will have been affected
