klaim baseline saldo stabil (V56/B18) + endpoint cek akun payout-eligible /api/voter (V57)

V56/B18: pre-claim liquid balance dibaca SEKALI per window (poll_claim) dan dibawa ke tiap _try_claim_once — klaim yang mendarat di attempt 1 membuat before attempt 2 (ditolak already-claimed) sudah termasuk reward → delta 0 → alert palsu KLAIM MENDARAT · REWARD TAK TERUKUR (kasus 10 Agt: bfa9ab02 reward 1679.3365 vs tx ditolak b0a8b2f9) ; oracle B18 attempt-1-mendarat → claimed + reward asli terukur

V57: db.py single source eligible_voters(owner=None) — SQL jendela payout V40/V52 (last_vote > now−STALE AND first_seen_at IS NOT NULL AND first_seen_at ≤ now−MATURITY, cutoff UTC-naive) dipakai BAIK distribute.py run_distribution (refactor, hapus _eligible_cutoffs) MAUPUN endpoint baru GET /api/voter/<owner> → 200 {owner, is_valid_voter} (DB-snapshot, selalu 200, ⊖ format-validation); BARU/kadaluarsa/hidden/asing → false ; docs §I/§V/V57 + T50 + AGENTS ; oracle test_dashboard (V57 true/false + drift endpoint==db pool + pool distribusi==db) + test_distribute (mock eligible_voters utk no-op, distribusi luas)
