hscontrol/debug.go — pre-size nodes []nodeStatus to len(debugInfo)
so the loop does not grow under append.
hscontrol/mapper/batcher_test.go — testing.TB parameter on
setupBatcherWithTestData renamed t → tb so thelper sees the
expected name.
hscontrol/db/text_serialiser.go — reflect.Ptr → reflect.Pointer
(deprecated alias).
Errors should not start capitalised and they should not contain the word error
or state that they "failed" as we already know it is an error
