Replay Divergence

Replay divergence occurs when reconstructed behavior does not satisfy the expected comparison rule.

  • input artifact
  • state snapshot
  • configuration
  • dependency assumptions
  • canonicalization rules
  • comparison contract
  • expected result

A replay boundary that is not referentially closed may depend on external state that was not preserved.

Identify the missing or varying dependency and make the replay boundary explicit.

Do not redefine equivalence after observing the result merely to force a match.
