+// The CWallet::AbandonTransaction API was added to Triangles to recover
+// from stuck or conflicted transactions without needing the heavy
+// `-zapwallettxes=1` hammer that wipes ALL unconfirmed wallet txs.
+//
+// These tests cover the validation paths (tx not in wallet, tx not
+// from this wallet, etc.). The success path requires a file-backed
+// wallet with a real on-disk DB, which is covered by the integration
+// regtest dry-run in scripts/ — boost unit tests use a non-file-backed
+// wallet (fFileBacked = false), so we only assert the rejection paths
+// here.
