Failed rows are recorded `failed` and rejoined by the next day's run — no manual cleanup needed. **Send safety (V59/V61)**: if a transfer broadcasts but Hyperion can't confirm it, the payment is held for real — marked `failed` at the first attempt and never re-signed (a resend would carry a fresh tapos/expiration → new txid → possible double-send). `verify_txid → None` (Hyperion unreachable) and `executed: false` (index lag, V50/B14) BOTH hold now — the send-loop exception path runs `_verify_settled` (retries the verify 3× with 2s delay to let Hyperion catch up; None → False immediately, pool fully dead) and only `True` marks `sent` + breaks, anything else holds (V61/B21). Chain rejections that come back as HTTP-500 bodies (pyntelope does NOT raise on them — duplicate/insufficient-balance, pattern V46/B11) are detected by `_send_rejected` (V61: WHITELIST — success is only a dict with `transaction_id` + receipt `executed`/no status; any other 500 body or soft_fail → rejected) and routed through the verify/retry path, never recorded `sent` for a tx that didn't land. All `/v2/*` reads guard `isinstance(data, dict)` so a non-dict 200 (proxy misconfig) is skipped, never a crash (V61/B23). **Node resilience (V58)**: all chain RPC calls fail over across the `API_NODES` pool (`VEX_API_NODES` CSV, default `v2.vexascan.com:2096` + `https://api.databisnis.id`) — balance fetch, ABI+TAPOS, and broadcast; the real-run balance fetch retries with backoff ~10 min before aborting to the next schedule, `--dry-run` fails fast. **Hyperion resilience (V60)**: every `/v2/*` read (`verify_txid`, `claim.reward_from_tx`, dashboard SALDO LIQUID) fails over across the `HYPERION_NODES` pool (`VEX_HYPERION_NODES` CSV, default = `HYPERION_API` + `API_NODES` dedup — both hosts verified to serve Hyperion) via `distribute._get_json` (GET mirror of the V58 `_post_json`, 3 rounds, 2s), so a single Hyperion blip no longer force-holds payments or fails reward measurement.
 - Daily reward claim (production): `./venv/bin/python claim_loop.py` — the `claim` service scheduler. `claim.py` computes the claim window as `last_claim_time + 24h` (from the `vexcore` `producers` table) in **UTC-naive time** (`_utcnow()`, matching the chain's UTC `last_claim_time`; the container's local TZ must not shift the window — V49/B13), sleeps until near it, then polls `vexcore::claimrewards` every `CLAIM_RETRY_SECONDS` (default 60) until the chain accepts; if 24h have already elapsed since the last claim the window clamps to now (missed-window recovery, no permanent spin-timeout). A claim is only treated as "landed" if Hyperion says `executed` OR `last_claim_time` actually advanced past its pre-send value (`_claim_time_advanced`) — on **both** the send-success and send-exception paths (`_confirm_landed`), because pyntelope's `send()` does NOT raise on a chain rejection (HTTP 500 comes back as a JSON body, V46/B11), and Hyperion returning `executed: false` for a just-landed-but-not-yet-indexed tx must NOT count as "didn't land" (V50/B14). Unconfirmed ⇒ silent `retry` (no `claim_runs` row, no success notify) — self-heals when Hyperion indexes the tx on the next poll. The landing baseline (`last_claim_time` before send) is captured **once per poll window** in `poll_claim` and passed to every `_try_claim_once` — it must NOT be re-read per attempt, or a landed-but-stale-first-read claim falls into a permanent retry loop (V54/B16); `_confirm_landed` also retries the post-send `last_claim_time` read so a lagging RPC node doesn't cause a false negative. The **pre-claim liquid balance** is likewise captured **once per poll window** (`before_balance`) and passed to every `_try_claim_once` (V56/B18) — if a claim lands on attempt 1, the next (rejected "already claimed") attempt must still measure the reward via the window-start balance, not a re-read `before` that already includes the credit (which reads delta 0 → false `KLAIM MENDARAT · REWARD TAK TERUKUR`, e.g. the 2026-08-10 claim `bfa9ab02…` reward 1679.3365 recorded against rejected tx `b0a8b2f9…`). `next_window` raises if all producer reads fail (never clamps to now prematurely). Reward is measured **from the claim tx itself** (sum of `vex.bpay`+`vex.vpay` → BP transfers via Hyperion, `reward_from_tx`), **retried up to 4× at `SETTLE_SECONDS` (30s)** so a just-landed tx not yet indexed by Hyperion doesn't read as `None` (V55/B17); if Hyperion is down it falls back to the liquid-balance delta, but **only a positive delta (`after > before`) counts as measured** — a 0 delta is ambiguous (stale node balance) and is treated as unmeasured, never as a genuine zero; if neither can be read the claim is recorded with fee `pending` and an internal `KLAIM MENDARAT · REWARD TAK TERUKUR` alert is sent (never a misleading 0-reward success — a real 0-reward claim must be evidenced by `reward_from_tx` returning `Decimal('0')` from an executed tx). 10% (`VEX_BP_FEE_PERCENT`) is transferred to `VEX_BP_FEE_WALLET` (default `bpdbsjasprod`) with memo `BP FEE YYYY-MM-DD`, reusing `distribute.build_signed_transfer`. A claim cycle is complete only when the claim is recorded in `claim_runs` AND the fee is sent; an unsent fee (`pending`/`failed`) is retried each cycle and resumed on restart (crash-safe). No mutex with `distribute.py` — distribution freezes the balance at run start, so a mid-run claim is deferred to the next run.
 - Storage backend: `db.py` abstracts it. Default `sqlite` (`VEX_DB_PATH`, stdlib `sqlite3`, WAL). Optional `mysql` (`VEX_DB_BACKEND=mysql` + `VEX_DB_HOST/PORT/USER/PASS/NAME`, PyMySQL). Oracle tests stay on sqlite; `test_mariadb.py` is opt-in (skips unless `VEX_DB_BACKEND=mysql`). Query SQL is written once with `%s` placeholders (translated to `?` for sqlite); `db.query` always returns a list.
 - Test MariaDB/MySQL via docker: `docker compose -f docker-compose.dev.yml up -d` (mariadb:11 container `databisnisid-mariadb`, localhost-only `127.0.0.1:3306`, db/user/pass `databisnisid`/`databisnis`/`databisnis`, named volume, healthcheck). Stop/remove with `docker compose -f docker-compose.dev.yml down`; wipe data with `docker compose -f docker-compose.dev.yml down -v`. Verify with `docker compose -f docker-compose.dev.yml exec mariadb mariadb -u databisnis -pdatabisnis databisnisid -e 'SELECT 1'`. Smoke against the container:
   `VEX_DB_BACKEND=mysql VEX_DB_HOST=127.0.0.1 VEX_DB_PORT=3306 VEX_DB_USER=databisnis VEX_DB_PASS=databisnis VEX_DB_NAME=databisnisid ./venv/bin/python test_mariadb.py`
 - Docker Swarm (production stack): images are registry-pushed `git.proit.id/proitlab/databisnisid-web` + `databisnisid-scan` + `databisnisid-dist` + `databisnisid-claim` — build & push them first (`docker build -t git.proit.id/proitlab/databisnisid-web . && docker push git.proit.id/proitlab/databisnisid-web`, same for the scan, dist and claim images), then from a swarm manager run `docker stack deploy -c docker-compose.yml databisnisid`. Stack = mariadb (internal) + web (gunicorn dashboard, published `:5001`; also receives `TZ` + `DISTRIBUTE_HOUR`/`DISTRIBUTE_WEEKDAY`/`DISTRIBUTE_FIRST_RUN` from `.env` for the BERITA banner, V38) + scan (`scan_loop.py`, runs `get_voters.py` at `SCAN_HOURS` default `0,8,16`, local timezone `TZ` default `Asia/Jakarta`, plus one scan at container start via `SCAN_RUN_ON_START`) + distribute (`distribute_loop.py`, runs `distribute.py` twice-weekly at `DISTRIBUTE_WEEKDAY` default `wed,sat` (CSV, multi-day V44) + hour `DISTRIBUTE_HOUR` default `10`, one-off `DISTRIBUTE_FIRST_RUN` default baked `2026-08-17`; schedule read via `config`, konsisten dgn dashboard); key `VEX_BP_PRIVATE_KEY` read from the bind-mounted `/app/.env` → host `/mnt/nfs/server5.saltis.id/data/databisnisid/app/config.env` via `config.py` `load_dotenv`, `:ro`) + claim (`claim_loop.py`, poll `claimrewards` at the 24h window, key + Telegram also from the same NFS bind). `mariadb` is pinned by `placement.constraints: node.hostname == server5.saltis.id` because its data lives in the host bind mount `/data/db/mariadb/databisnisid/data` on that node; `web`/`scan`/`distribute`/`claim` exclude node `server2U` (`node.hostname != server2U`) but otherwise can run on any node and reach it over the overlay network `appnet`. Inspect: `docker stack services databisnisid`, `docker service logs databisnisid_scan`, `docker stack rm databisnisid`. `docker stack deploy` ignores `build:` (images must already be in the registry) and ignores `env_file` (env is inlined with `${VAR}` interpolation from `.env`). The local dev box has no swarm anymore (torn down) — if you re-init one there, the mariadb constraint leaves that task **Pending** since no node is named `server5.saltis.id`.
 - Web dashboard (read-only, reads the store via `db.py`): production `./venv/bin/gunicorn -c gunicorn.conf.py dashboard:app` → http://127.0.0.1:5000/ (run from repo dir). Easier: `./run.sh` (same command, works from any cwd, `$@` passed through). `gunicorn.conf.py` imports `config` → `.env` honored; `DASH_WORKERS` (default 2) controls workers, `DASH_HOST`/`DASH_PORT` the bind. Dev server (single-process) still works via `./venv/bin/python dashboard.py`. Vote bands (V40/V42/V52): BARU (new first-time voters, `first_seen_at` within 3 days, own table on top, never paid — maturity is measured from `first_seen_at`, NOT `last_vote` which is week-quantized) → main list: KADALUARSA (28–31 days, pinned amber rows at the top with `VOTE ULANG` badge + legend) then VALID (the paged 50/page list, `staked DESC`, live owner search via `/api/search`); voters older than 31 days are stored by the scan but hidden. Since V42, **REVOTE** (returning voters, `voter_first_seen.first_seen_at ≤ now−3d`) are VALID immediately — they join the main list tagged with a mint `REVOTE` tag (legend `TAG MINT = REVOTE KURANG DARI 1 HARI · VALID LANGSUNG`), no separate band, no maturity wait; since V43 the mint tag shows only while `last_vote > now−VEX_REVOTE_TAG_DAYS` (default 1 day) — after that they're plain VALID (still paid); VALID rows within `VEX_WARN_DAYS` (default 3) of the KADALUARSA cutoff get an amber dashed `VOTE ULANG SEGERA` badge (legend `TAG AMBER = KADALUARSA DALAM 3 HARI · N PEMILIH`); only genuinely new voters pass the 3-day maturity in BARU. Data freshness comes from the daily scan run — the dashboard never scans.

They mock the network / use a temp DB — the live node is too flaky/slow for a full-scan test. Run after touching the relevant file.
 
@@ -29,10 +29,10 @@ Two tools scan the Vexanium blockchain voters table for accounts whose only vote
 - Freshness filter (spec §V13/V40): `last_vote` (estimated last re-vote date) is derived at scan time from the Vexanium weight formula `last_vote_weight = staked_raw × 2^(weeks since 2000 / 52)` → `last_vote = 2000-01-01 + round(52 × log2(weight / (staked×10000))) weeks` — the chain (`stake2vote`) quantizes the exponent to whole weeks (`int64((now−2000-01-01)/(86400×7))/52.0`), so derived dates land on 7-day boundaries (B12; earlier 365.25-day divisor drifted ~33 days forward for 2026 votes). Since V40 `normalize()` stores **every** BP voter with a derivable `last_vote` — any age; only unverifiable votes (zero/empty weight) are dropped. Banding (BARU/VALID/KADALUARSA), display and payout are computed at query time (dashboard cuts 28/31 days on `last_vote` age; distribution pays `last_vote > now−28d`). **Maturity (3 days) is measured from `first_seen_at`, not `last_vote`** — `last_vote` is week-quantized so a new voter voting Mon–Thu would look 4–6 days old and bypass the wait (B15); V52 uses `voter_first_seen.first_seen_at` (scan-precise to the second) for the new-voter wait. The heuristic over-reads when a voter unstaked without re-voting (weight ÷ smaller stake ⇒ future date), so `normalize()` clamps any `last_vote` past scan time down to `now`. Since V41, `voter_first_seen.first_seen_at` separates PEMILIH BARU (new, first-seen within the 3-day maturity) from REVOTE (returning re-voters); since V42 REVOTE are VALID immediately (paid + shown in the main list, mint tag), only new voters wait out maturity; since V43 the mint tag lasts only `VEX_REVOTE_TAG_DAYS` (1) and VALID rows nearing the KADALUARSA cutoff (within `VEX_WARN_DAYS`, 3) get a `VOTE ULANG SEGERA` badge — display-only.
 - The web list shows RANK / AKUN / STAKE (VEX) / TOTAL REWARD (VEX) / VOTE TERAKHIR columns (3 stats cells). TOTAL REWARD = all-time sum of `distribute_payments.amount` where `status='sent'` (0,0000 for never-paid), joined per page via a LEFT JOIN subquery. Vote weight stays in the DB and `/api/search` JSON but is not rendered as a column.
 - Token contract is `vex.token` (NOT `eosio.token` — that name doesn't exist on Vexanium), 4-decimal VEX, chain_id `f9f432b1851b5c179d2091a96f593aaed50ec7466b74f89301f957a83e56ce1f`. Distribution signs `vex.token::transfer` with the BP `active` key.

 - Claim (spec §V32–V34): the BP reward is claimed once per 24h window via `vexcore::claimrewards` (`owner` = BP). The `claim` service polls every `CLAIM_RETRY_SECONDS` only near the window (`last_claim_time` from the `vexcore` `producers` table + 24h) — no all-day tx spam; a window already ≥24h past clamps to now so a missed claim is caught up, never spin-timeout (B8). `get_table_rows` responses are always `{"rows":[...]}` — parse `data.get('rows')`, never `data[0]` (B7, V39). Landed detection = Hyperion `executed` OR `last_claim_time` advanced past pre-send value, checked on BOTH the send-success and send-exception paths (`_confirm_landed`) because pyntelope's `send()` returns HTTP 500 as a body instead of raising on a chain rejection (V46, B11); Hyperion `executed: false` on a not-yet-indexed tx still falls back to the `last_claim_time` advance check (V50, B14). `next_window` raises if all producer reads fail so a flaky node never triggers a premature claim. Reward = sum of `vex.bpay`+`vex.vpay` → BP transfers read from the claim tx via Hyperion (`reward_from_tx`), balance-delta as fallback (V33); if neither can be read → fee `pending` + internal `KLAIM MENDARAT · REWARD TAK TERUKUR` alert, never a misleading 0-reward success (B10). 10% fee floored at 4-dec goes to `bpdbsjasprod` (`VEX_BP_FEE_WALLET`), memo `BP FEE YYYY-MM-DD`, txid verified via Hyperion before any resend. A cycle completes only when the claim row (`claim_runs`) is recorded AND the fee is `sent`; an unsent fee is retried each cycle and resumed on restart. No mutex with distribution — the daily payout freezes the balance at run start, so a claim landing mid-run is simply paid out the next run.

The dashboard still never writes to the DB.
