Apply an anti-entropy repair range: A partial range response is marked fully repaired · case 02

The anti entropy repair operation is admitted even though a partial range response is marked fully repaired.

Case contract

Return a Boolean admission decision for apply an anti-entropy repair range. The record r must satisfy all of: all(r['range_ownership'][0] <= x < r['range_ownership'][1] for x in r['range_ownership'][2]); r['version_monotonic'][0] >= r['version_monotonic'][1]; r['tombstone_horizon'][0] >= r['tombstone_horizon'][1]; r['merkle_generation'][0] == r['merkle_generation'][1]; r['range_complete'][0] == r['range_complete'][1]. Extra tracing fields are ignored; validation does not mutate the record.

Why this case matters

A deterministic local contract for replication. Each negative fixture violates exactly one invariant. No transport timing, persistence, cryptographic verification, or full protocol implementation is claimed.

One recorded failure

Sample boundary fixture

This sample comes from the broken implementation of a controlled reproducer.

Boundary fixture	Actual	Expected	Outcome
A partial range response is marked fully repaired	`true`	`false`	Failed
