Run a saga compensation action: Compensation reverses a forward action that never committed · case 04
The saga compensation operation is admitted even though compensation reverses a forward action that never committed.
Case contract
Return a Boolean admission decision for run a saga compensation action. The record r must satisfy all of: r['forward_committed'] is True; all(r['reverse_dependency']); r['compensation_identity'][0] not in r['compensation_identity'][1]; r['resource_version'][0] == r['resource_version'][1]; r['compensation_registered'] is not None. Extra tracing fields are ignored; validation does not mutate the record.
Why this case matters
A deterministic local contract for workflow orchestration. Each negative fixture violates exactly one invariant. No transport timing, persistence, cryptographic verification, or full protocol implementation is claimed.
One recorded failure
Sample boundary fixtureThis sample comes from the broken implementation of a controlled reproducer.
| Boundary fixture | Actual | Expected | Outcome |
|---|---|---|---|
| Compensation reverses a forward action that never committed | true | false | Failed |
