Admit a conflict resolution result: A merge result violates the application value constraint · case 05

The conflict resolution operation is admitted even though a merge result violates the application value constraint.

Case contract

Return a Boolean admission decision for admit a conflict resolution result. The record r must satisfy all of: set(r['parent_coverage'][0]) <= set(r['parent_coverage'][1]); all(a >= b for a,b in zip(r['clock_dominance'][0],r['clock_dominance'][1])); len(set(r['resolver_version'])) == 1; tuple(r['new_dot'][0]) not in [tuple(x) for x in r['new_dot'][1]]; r['result_domain'] >= 0. 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 merge result violates the application value constraint	`true`	`false`	Failed
