 - Node reference script: `node get_voters.js` (no deps, Node 18+).
 - Python tool (production): `./venv/bin/python get_voters.py`. venv is Python 3.12, deps `requests` + `flask` + `python-dotenv` (`requirements.txt`). Install with `./venv/bin/pip install -r requirements.txt`.
 - Web dashboard (read-only, reads `voters.db`): production `./venv/bin/gunicorn -c gunicorn.conf.py dashboard:app` → http://127.0.0.1:5000/ (run from repo dir). `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`. Paged 50/page, sorted `staked DESC`, live owner search (`/api/search`). Data freshness comes from the daily scan run — the dashboard never scans.

@@ -22,6 +22,7 @@ Two tools scan the Vexanium blockchain voters table for accounts whose only vote
 - Authoritative vote weight is `last_vote_weight` (high-precision decimal string) — stored verbatim as TEXT, never float-converted (spec §V6).
 - Freshness filter (spec §V13): `last_vote` (estimated last re-vote date) is derived at scan time from the Vexanium weight formula `last_vote_weight = staked_raw × 2^(years since 2000)` → `log2(weight / (staked×10000))`. Voters whose `last_vote` is older than `VEX_STALE_DAYS` (default 28) — or can't be derived (zero/empty weight) — are dropped in `normalize()` and never stored; the dashboard therefore shows only fresh voters (no stale UI). 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`.
 - The web list shows RANK / AKUN / STAKE (VEX) / VOTE TERAKHIR columns (3 stats cells). Vote weight stays in the DB and `/api/search` JSON but is not rendered as a column.
+- Liquid balance (spec §V16): a 4th stat cell "SALDO LIQUID" shows the BP account's liquid VEX (`account.core_liquid_balance`) fetched from `GET {DATABISNIS_API}/v2/state/get_account?account=<BP>`. The dashboard fetches it live but caches per-worker in memory for `DASH_LIQUID_TTL` (default 60s); a failed fetch keeps the last value (or renders `—` if none ever succeeded) and the failure is also cooled-down so the API isn't hammered. The dashboard still never writes to the DB.
