Your build starts here
Replace bracketed details with your own goal, context, and checks. Keep the first build small enough to inspect.
Add a diagnostic replay probe for [gameplay system] in [specified build and target environment]. Record the initial state, ordered gameplay inputs, simulation-step identity, required random state, and relevant content/configuration versions. State which behavior the replay is intended to reproduce and which presentation effects are excluded.
Replay the recording without live input. Compare a small normalized set of meaningful state values at agreed checkpoints and report the first mismatch with its preceding inputs. Keep wall-clock reads, unrelated randomness, and iteration order visible as possible divergence sources. Do not claim that one seed establishes reproducibility across engine releases or hardware.
Verify two runs under the same supported conditions, then deliberately change one input and one recorded version to check that the probe detects an appropriate difference. Deliver the recording format, comparison evidence, and unresolved determinism assumptions.Make this prompt yours
Start with a small isolated mechanic. A diagnostic replay is useful even when the whole game is not deterministic.

Qualified: Original diagnostic template. Recorded random state and bounded build conditions are appropriate; Godot does not guarantee deterministic physics. The existing text asks for unresolved assumptions and does not promise cross-version/hardware replay.
