  "summary": "Strengthens the `private_broadcast` fuzz target to verify that `PrivateBroadcast::GetStale()` returns the exact set of expected stale transactions. The harness now records transaction addition timestamps and peer confirmation times to compute expected staleness and asserts that the returned transactions match.",
  "problem": "The existing fuzz harness verifies that returned transactions are valid candidates, but does not check for completeness. A bug or mutation in `GetStale()` that silently omits stale transactions (such as prematurely breaking out of iteration) would leave them unretried by `ReattemptPrivateBroadcast()` while still passing fuzz tests.",
  "card": "Strengthens the private broadcast fuzz target by tracking transaction addition and peer confirmation times to assert that GetStale() returns the exact expected set of stale transactions. The fuzz harness previously only checked that returned transactions were valid candidates, allowing mutations like changing continue to break to go undetected. Because ReattemptPrivateBroadcast() only retries transactions returned by GetStale(), any omitted transactions are silently abandoned.",
  "evidence": [
   "PR description notes that in mutant testing (mutanthub.space/mutants/3752), changing `continue` to `break` in `GetStale()` passed all current tests.",
