Spectre.Determinism.Source behaviour (Spectre v0.3.2)

Copy Markdown View Source

Host port for decision-relevant clock and randomness samples.

The default implementation delegates to the Erlang runtime. Replay and audit integrations may provide a source through :determinism_source; the source is resolved at the boundary and is never persisted inside a Run.
