- It was found through static analysis that in some cases, TLVWriters did not have all fields initialized and this led to no errors, but possibly could lead to bad states. - None of the code making use of uninitialized TLVWriters was found in the SDK, but there may be usages. - In adding the checks, marked several areas that could be improved in TLVWriter data access/management. Issue project-chip#30825 Testing done: - All tests still pass. - There is never uninitialized used of a TLVWriter.
