distribusi hardened vs node mati + send ⊖ pernah menyesatkan (V58/V59)

V58 failover node pool: config += API_NODES (CSV VEX_API_NODES, default
v2.vexascan.com:2096 + https://api.databisnis.id, mainnet terverifikasi) ;
distribute _post_json coba SEMUA node per putaran (semua mati → RuntimeError),
build_signed_transfer coba tiap node utk link+sign (net ter-bind → send ikut
node sama), fetch_balance_with_retry backoff [30..180]s ~10 mnt real-run /
dry-run satu attempt ; scan/claim tetap API_NODE tunggal, fee klaim mewarisi
failover gratis ; oracle failover saldo + semua-mati raise + backoff + mock Net

V59 send aman per pemilih (B19): (1) verify_txid → None (Hyperion down) =
TAHAN sungguhan — break + failed di attempt 1, ⊖ resend dgn tapos/expiration
baru → txid baru → double-send (kode lama cuma print ditahan lalu fallthrough
ke retry, oracle lolos karena set MAX_ATTEMPTS=1) ; (2) _send_rejected(resp)
deteksi body HTTP-500 pyntelope ⊖ raise (pola V46/B11, duplicate/
insufficient-balance) → raise → jalur verify/retry, ⊖ pernah sent utk tx yang
⊥ mendarat ; oracle hold-attempt-1 (3 attempt default, build sekali per pemilih)
+ rejection-500 → failed ; docs §V58/V59 + §B/B19 + T51/T52 + AGENTS
