Field notes
The system is split into an open recording layer and a hosted diagnosis layer. Temper writes ExUnit outcomes and commit identifiers to JSONL, then a CI step pushes the history; Sinter compares outcomes across retries and partitions without running tests or reading source code. The page illustrates the method with an ImportTest marked 23% flaky and a ParserTest marked 8% flaky, and lists Elixir-specific causes such as sandbox ownership and order dependency.
