What this target establishes
Scope metadata is the contributor’s assessment; independent reviews and the exact proposition provide the evidence.
- Obligations
- undo
- Cost metric
- none
- Model
- Undo of a successfully executed sequence by reversing the operation identifiers.
- Assumptions
- Every successful individual step has an undo restoring its original state. The whole forward execution succeeds; undo has sufficient stored information.
- Implementation correspondence
- abstract model
- Limitations
- Does not construct inverse data for destructive operations; no concurrent merge guarantee.
